[Tracheotomy: discussion of various surgical procedures using argon plasma coagulation].

BACKGROUND: At present there is a discernible lack of consensus among different medical specialties regarding methods of tracheotomy in an intensive care setting. There is an obvious preference for percutaneous dilatational tracheotomy methods. Comparison of different methods are necessary to determine whether this trend is justified. METHOD: ENT and intensive care departments together performed 270 tracheotomies using different techniques in longtime-intubated adults over a period of 4 years. Severe complications were compared. Twenty conventional surgical tracheotomies were performed by using argon-plasma coagulation (APC). RESULTS: Comparison of 2175 percutaneous and 3263 conventional surgical tracheotomies reveals a nearly identical rate of severe perioperative complications. Percutaneous methods are most frequently used in patients with initially uncomplicated conditions. CONCLUSIONS: On the basis of our experience with 270 tracheotomies we have found there are clear indications for the various methods of tracheotomy. They depend on both the history of the disorder and its course and on the known contraindications to percutaneous tracheotomy methods. For safety reasons, we do not perform percutaneous tracheotomies on patients with severe brain damage who tend to aspirate and require prolonged neurological rehabilitation. Preoperative bleeding in percutaneous tracheostomies is the most important complication. It led to a life-threatening situation in 2.4% of our cases. Preoperative neck ultrasound may decrease the risks due to unusual anatomical conditions. Comparison of significant perioperative complications does not appear to favor any one method at present. In light of our effective cooperation with other specialties in planning and performing tracheotomies we do not feel that the current general preference for percutaneous methods in intensive care medicine is justified. Initial experience with APC shows promising results concerning its use in conventional tracheotomies. However, we noticed a shorter operation time, reduction of bleeding complications, and use of less suture material. The effectiveness of surgical intervention is improved by a number of factors.

Tracheotomy complications: a retrospective study of 1130 cases.

BACKGROUND: Tracheotomy is one of the most frequently performed surgical procedures in the critically ill patient. It is frequently performed as an elective therapeutic procedure and only rarely as an emergency procedure. Complications occur in 5% to 40% of tracheotomies depending on study design, patient follow-up, and the definition of the different complications. The mortality rate of tracheotomy is less than 2%. Numerous studies demonstrate a greater complication and mortality rate in emergency situations, in severely ill patients, and in small children. METHODS: A retrospective study of 1130 consecutive tracheotomies performed during 1 decade (January 1987 through December 1996) is presented. We studied the indications for surgery, the major complications of tracheotomy, and their treatment and outcome. We also noted the overall mortality rate and the specific complications that led to these deaths. RESULTS: In total, 1130 tracheotomies were performed. Major complications occurred in 49 of the cases, and 8 deaths were directly attributed to the tracheotomy. The most common complication was tracheal stenosis, which occurred in 21 cases. Hemorrhage was the second most common complication, which occurred in 9 cases. CONCLUSION: This is one of the largest series of consecutive tracheotomies compiled. We found a relatively low overall complication and mortality rate compared with other large series. Tracheal stenosis was the most common complication in contrast to other series. Our opinion is that this may reflect tracheal damage originally caused by prolonged intubation before the tracheotomy. We believe that all other complications of tracheotomy may be prevented or minimized by careful surgical technique and postoperative tracheotomy care.

Pediatric tracheotomies: changing indications and outcomes.

OBJECTIVE/HYPOTHESIS: To study the outcomes and complications associated with pediatric tracheotomy, as well as the changing trend in indications and outcomes since 1970. STUDY DESIGN: Retrospective chart review at a major tertiary care children's hospital. METHODS: On children who underwent tracheotomy at Children's Hospital of the King's Daughters (Norfolk, VA) between 1988 and 1998, inpatient and outpatient records were reviewed. Of 218 tracheotomies, sufficient data were available on 204. Indications for tracheotomy were placed into the following six groups: craniofacial abnormalities (13%), upper airway obstruction (19%), prolonged intubation (26%), neurological impairment (27%), trauma (7%), and vocal fold paralysis (7%). RESULTS: The average age at tracheotomy was 3.2 +/- 0.6 years. Although the prolonged intubation group was significantly younger than all others, the neurological impairment and trauma groups were significantly older. Decannulation was accomplished in 41%. Time to decannulation was significantly higher in the neurological impairment and prolonged intubation groups, but was significantly shorter in the craniofacial group. Complications occurred in 44%. Overall mortality was 19%, with a 3.6% tracheotomy-related death rate. Comparison of our series to other published series of pediatric tracheotomies since 1970 shows fewer being performed for airway infections and more for chronic diseases, with a corresponding increase in duration of tracheotomy and decreased decannulation rates. CONCLUSIONS: Tracheotomy is a procedure performed with relative frequency at tertiary care children's hospitals. While children receiving a tracheotomy have a high overall mortality, deaths are usually related to the underlying disease, not the tracheotomy itself.

Tracheotomy does not affect reducing sedation requirements of patients in intensive care--a retrospective study.

INTRODUCTION: Translaryngeal intubated and ventilated patients often need sedation to treat anxiety, agitation and/or pain. Current opinion is that tracheotomy reduces sedation requirements. We determined sedation needs before and after tracheotomy of intubated and mechanically ventilated patients. METHODS: We performed a retrospective analysis of the use of morphine, midazolam and propofol in patients before and after tracheotomy. RESULTS: Of 1,788 patients admitted to our intensive care unit during the study period, 129 (7%) were tracheotomized. After the exclusion of patients who received a tracheotomy before or at the day of admittance, 117 patients were left for analysis. The daily dose (DD; the amount of sedatives for each day) divided by the mean daily dose (MDD; the mean amount of sedatives per day for the study period) in the week before and the week after tracheotomy was 1.07 +/- 0.93 DD/MDD versus 0.30 +/- 0.65 for morphine, 0.84 +/- 1.03 versus 0.11 +/- 0.46 for midazolam, and 0.62 +/- 1.05 versus 0.15 +/- 0.45 for propofol (p < 0.01). However, when we focused on a shorter time interval (two days before and after tracheotomy), there were no differences in prescribed doses of morphine and midazolam. Studying the course in DD/MDD from seven days before the placement of tracheotomy, we found a significant decline in dosage. From day -7 to day -1, morphine dosage (DD/MDD) declined by 3.34 (95% confidence interval -1.61 to -6.24), midazolam dosage by 2.95 (-1.49 to -5.29) and propofol dosage by 1.05 (-0.41 to -2.01). After tracheotomy, no further decrease in DD/MDD was observed and the dosage remained stable for all sedatives. Patients in the non-surgical and acute surgical groups received higher dosages of midazolam than patients in the elective surgical group. Time until tracheotomy did not influence sedation requirements. In addition, there was no significant difference in sedation between different patient groups. CONCLUSION: In our intensive care unit, sedation requirements were not further reduced after tracheotomy. Sedation requirements were already sharply declining before tracheotomy was performed.

Time to wean after tracheotomy differs among subgroups of critically ill patients: retrospective analysis in a mixed medical/surgical intensive care unit.

OBJECTIVE: To determine the time to wean from mechanical ventilation and time spent off the ventilator per day after tracheotomy in critically ill patients in a 28-bed mixed medical and surgical intensive care unit (ICU) in Amsterdam, Netherlands. METHODS: We conducted a retrospective analysis of consecutive patients during the 14-month period from November 1, 2003, through January 1, 2005. Included were translaryngeally intubated mechanically ventilated patients who received a tracheotomy during their ICU stay. RESULTS: Of all the patients admitted to the ICU, 129 (7%) received a tracheotomy. Significantly more tracheotomies were performed in neurosurgery/neurology patients and in those admitted for acute conditions (16% and 12%, respectively). Tracheotomy was performed a median 8 days (interquartile range 4-13 d) after ICU admission. For all the patients, the median time to wean after tracheotomy was 5 days (interquartile range 2-11 d). Neurosurgery/neurology patients and patients in the cardiology subgroup needed significantly less time to wean from mechanical ventilation than did patients in other subgroups (3 d, interquartile range 2-7 d, and 3 d, interquartile range 2-5 d, respectively, p < 0.05). There was a significant association between admission group and neurological status at the time of tracheotomy. A low Glasgow coma scale score was associated with shorter time to wean. Within 1 week after tracheotomy, the probability of the patient having breathed spontaneously, without ventilator assistance, for > 4 h/d was 89%, 78% for > 8 h/d, and 72% for > 12 h/d. By day 28, the probability of the patient having breathed spontaneously for > 4 h/d was 98%, 97% for > 8 h/d, and 94% for > 12 h/d. CONCLUSION: Time to wean from after tracheotomy differed among the subgroups in our ICU. After tracheotomy, the majority of patients were quickly able to breathe spontaneously without assistance of the mechanical ventilator for several hours per day. Patients who require tracheotomy only for airway protection wean sooner than other patients.

Bronchoscopy and laryngoscopy findings as indications for tracheotomy in the burned child.

OBJECTIVE: To determine possible indications for tracheotomy in the burned child based on bronchoscopic and laryngoscopic findings. DESIGN AND SETTING: A retrospective case study of all patients admitted to a tertiary children's burn center. PARTICIPANTS: All children admitted with burn inhalation injury between 1990 and 1995 (n = 211). INTERVENTION: All patients underwent laryngoscopy and bronchoscopy and 19 underwent tracheotomy, with 5 tracheotomy tubes placed emergently. MAIN OUTCOME MEASURES: Observations during laryngoscopy and bronchoscopy included erythema, edema, carbonaceous material, ulcerations, and bronchial mucous casts. The supraglottis, glottis, and subglottis were analyzed separately, when possible. Any sepsis resulting from tracheotomy was determined. Complications, such as glottic webs, subglottic stenosis, and tracheomalacia, were noted. RESULTS: Indications for tracheotomy included 6 for airway obstruction, 6 for prolonged intubation, 6 for pulmonary cleansing, and 1 for endotracheal tube complications (subglottic stenosis). When examined by bronchoscopy and laryngoscopy, 17 of 19 children had significant airway edema, 10 had carbonaceous material in the airway, and 3 had ulcerations in the airway. CONCLUSIONS: Tracheotomy is indicated in the burned child when significant airway edema is present. Failure to place a tracheotomy tube in these cases leads to a high incidence of immediate tracheotomies (26%). There was no evidence of clinically significant infection attributable to tracheotomy. The number of airway complications due to tracheotomy was no higher than from endotracheal intubation.

Tracheotomy in pediatric patients: a national perspective.

BACKGROUND: During the past 50 years, changes in the epidemiology of infectious diseases and the capabilities of medical technology have altered the indications for, and implications of, tracheotomy in children. Given the complexity of health care that these patients subsequently require, monitoring the performance of this procedure and patient outcomes across the diverse US health care system is warranted. OBJECTIVES: To characterize children who received tracheotomies in 1997 and to determine whether disposition and mortality vary by region or health care system attributes. DESIGN: A nationally representative retrospective cohort drawn from an 80% sample of administrative hospital discharge records from all pediatric admissions in 22 states during 1997. PARTICIPANTS: Patients aged 0 to 18 years who underwent tracheotomy. METHODS: The sampling scheme of the discharge records enabled the calculation of regional and national estimates and of age-stratified population-based rates of tracheotomies. Weighted descriptive statistical and Poisson analyses were performed. RESULTS: The 2065 tracheotomy procedures recorded in the Kids' Inpatient Database yielded a national estimate of 4861 tracheotomies performed in 1997. The mean length of hospital stay was 50 days, with a mean total facilities charge exceeding $200,000. The rate of tracheotomy was highest among infants and varied significantly across regions of the United States. Adjusting for other patient and health care system attributes, patients who received their tracheotomy in a children's hospital had half the risk of dying during the admission compared with patients who were cared for in a non-children's hospital. Hospitals that performed more pediatric tracheotomies had significantly lower mortality rates than hospitals with lesser case volume. Among patients who survived to discharge, those cared for in the Northeast were discharged to long-term care facilities at twice the rate of patients in the West. Children cared for in children's hospitals or in teaching hospitals were significantly less likely to be discharged to a long-term care facility. CONCLUSIONS: Pediatric tracheotomy is associated with significant variation in rates and outcomes across the United States and across different hospital types. Further research to clarify the reasons for these associations is warranted.

Effects of the removal of the tracheotomy tube on swallowing during the fiberoptic endoscopic exam of the swallow (FEES).

This study investigated the effects, if any, that the presence of a tracheotomy tube has on the incidence of laryngeal penetration and aspiration in patients with a known or suspected dysphagia. This was a prospective, repeated-measure design study. A total of 37 consecutive patients with a tracheotomy tube underwent a fiberoptic endoscopic evaluation of swallowing (FEES). Patients were first provided with pureed food boluses with the tracheotomy tube in place. The tracheotomy tube was then removed and the tracheostoma site was covered with gauze and gentle hand pressure was applied. The patients were then evaluated without the tracheotomy tube in place with additional puree. Aspiration status was in agreement with and without the tracheotomy tube in place in 95% (35/37) of the patients. The two patients who demonstrated a different swallowing pattern with regard to aspiration demonstrated aspiration only when the tracheotomy tube was removed. Laryngeal penetration status was in agreement with and without the tracheotomy tube in place in 78% (29/37) of the patients. For the majority of the patients, the removal of the tracheotomy tube made no difference in the incidence of aspiration and/or laryngeal penetration. Results of this study do not support the clinical notion that the patient's swallowing function will improve once the tracheotomy tube has been removed.

Tracheotomy in children with juvenile-onset recurrent respiratory papillomatosis: the Children's Hospital of Pittsburgh experience.

Despite the risk of airway obstruction, tracheotomy has been viewed with trepidation in the management of recurrent respiratory papillomatosis (RRP). The literature suggests that the injury associated with the tracheotomy site may initiate the progression of disease to the distal airway. Alternatively, patients who require tracheotomy for RRP may be predisposed to distal spread because of more aggressive disease. In an effort to clarify this issue, we reviewed the Children's Hospital of Pittsburgh experience with 35 patients with RRP between 1984 and 1994; 13 patients received tracheotomies. Tracheotomy patients presented at a younger age with more widespread disease, often involving the distal airway prior to tracheotomy. Although distal spread occurred in 50% of patients, it was generally limited to the tracheotomy site. Overall, outcome in the tracheotomy group was satisfactory. Complications related to the tracheotomy were rare. We conclude that tracheotomy is an appropriate option for significantly airway compromise in patients with RRP.

Indications for tracheotomy in the pediatric intensive care unit population: a pilot study.

OBJECTIVE: To define the indications for tracheotomy in patients requiring prolonged intubation (>1 week) in the pediatric intensive care unit (PICU). DESIGN: Retrospective chart review and follow-up telephone survey. SETTING: A tertiary care center PICU. OUTCOME MEASURE: Tracheotomy or extubation. PATIENTS: All patients older than 30 days in the PICU intubated for longer than 1 week between 1997 and 1999. RESULTS: During the study, 63 total admissions required intubation for longer than 1 week. A tracheotomy was necessary in 14% of admissions (n = 9). The mean length of intubation before the tracheotomy was 424 hours, whereas the mean length of intubation without the need for tracheotomy was 386 hours. Length of intubation, age, and number of intubations did not increase the probability of having a tracheotomy. Of those requiring a tracheotomy, 2 had tracheomalacia, 1 had subglottic edema, 1 had plastic bronchitis, 1 had Down syndrome with apnea resulting in right heart failure, 3 required long-term ventilation after cardiopulmonary collapse, and 1 had mitochondrial cytopathy. Of these 9 children, 7 were successfully decannulated, 1 patient died of underlying disease, and 1 patient remained cannulated secondary to the mitochondrial cytopathy. Twenty families of the patients who did not undergo a tracheotomy were reached by telephone after discharge. Most of the families reported that their children were free of stridor and hoarseness after extubation. CONCLUSIONS: Children tolerate prolonged intubation without laryngeal complications. The consideration for tracheotomy in the PICU setting must be highly individualized for each child.

Presence of a tracheotomy tube and aspiration status in early, postsurgical head and neck cancer patients.

BACKGROUND: We sought to investigate the effects, if any, that the presence of a tracheotomy tube has on aspiration status in early, postsurgical head and neck cancer patients. METHODS: Twenty-two consecutive adult, postoperative head and neck cancer patients were prospectively evaluated with fiberoptic endoscopic evaluation of swallowing (FEES) under three conditions: (1) tracheotomy tube present, (2) tracheotomy tube removed and tracheostoma covered with gauze sponge; and (3) tracheotomy tube removed and tracheostoma left open and uncovered. For each condition, the endoscope was first inserted transnasally to determine aspiration status during FEES and then inserted through the tracheostoma to corroborate aspiration status by examining the distal trachea inferiorly to the carina. Three experienced examiners determined aspiration status under each condition and endoscope placement. RESULTS: There was 100% agreement on aspiration status between FEES results and endoscopic examination through the tracheostoma. Specifically, 13 of 22 patients (59%) swallowed successfully and nine of 22 (41%) aspirated. There was also 100% agreement on aspiration status for tracheotomy tube present, decannulation and tracheostoma covered by gauze sponge, and decannulation and tracheostoma left open and uncovered. CONCLUSIONS: Neither presence of a tracheotomy tube nor decannulation affected aspiration status in early, postsurgical head and neck cancer patients. The clinical impressions that a tracheotomy or tracheotomy tube increases aspiration risk or that decannulation results in improved swallowing function are not supported. Rather, need for a tracheotomy indicates comorbidities (eg, respiratory failure, trauma, stroke, advanced age, reduced functional reserve, and medications used to treat the critically ill) that by themselves predispose patients for dysphagia and aspiration.

Pediatric tracheotomies in an Asian population: the Singapore experience.

OBJECTIVE: Over the past 2 decades, tracheotomy in children and infants has evolved from a primarily emergent procedure for upper airway obstruction into a semielective procedure for airway access in assisted ventilation. We present a 12-year retrospective review of tracheotomies performed in the pediatric population in Singapore. STUDY DESIGN AND SETTING: We reviewed all tracheotomies performed in children below the age of 16 years in 2 tertiary pediatric medical centers in Singapore from January 1991 to December 2003. Indications for surgery are reviewed, and outcomes in terms of morbidity rate, mortality rate, postoperative rehabilitation, and duration of decannulation process were analyzed. RESULTS: Tracheotomies were performed in 48 children during the study period. The mean age of patients was 3.24 years, with ages ranging from 16 days to 14 years. Sixty-three percent of tracheotomies were done within the 1st year of life. The chief indication was airway access for assisted ventilation. The overall complication rate was 31%. There were 13 attempts at decannulation, with 9 successes. No tracheotomy-related deaths occurred. CONCLUSION: Tracheotomy is a relatively safe procedure in children and infants. Lower decannulation rates and the evolving role of tracheotomy for early access in assisted ventilation permits earlier discharge with tracheotomy in situ.

Tracheotomy and the intensive care unit patient.

Transportation of the intensive care unit (ICU) patient to the operating room for tracheotomy has been implicated as an unnecessary source of complications and has been cited as a relative indication for percutaneous tracheotomy. However, there is very little evidence in the literature to support this claim. We evaluated 100 consecutive patients who were transported from the ICU to the operating room for tracheotomy. There were no complications related to patient transportation. A total of five complications occurred, all unrelated to patient transportation. Two patients receiving pressure control ventilation developed a pneumothorax on postoperative days 7 and 8, respectively. There were three minor complications directly related to the tracheotomy: peristomal cellulitis, tracheitis, and hemorrhage of less than 25 cc on postoperative day 1. The minor complications were treated appropriately and resolved without any adverse sequelae. We provide a detailed review of 100 consecutive ICU patient tracheotomy cases and compare this with 109 tracheotomies in non-ICU patients. Transportation of the ICU patient does not appear to increase the risk of complications during tracheotomy and should not be cited as a cause of complications in the percutaneous tracheotomy literature. The results with standard surgical tracheotomy in the controlled setting of the operating room should serve as the standard by which other procedures are judged.

Open bedside tracheotomy in the intensive care unit.

OBJECTIVE: To demonstrate that open bedside tracheotomy is an efficient, safe, and cost-effective procedure. STUDY DESIGN: Retrospective review of more than 200 open bedside tracheotomies performed at UCLA Medical Center, Harbor-UCLA Medical Center, and West Los Angeles VA Medical Center from 1995 to 1998. METHODS: The only personnel required for the procedure were an attending or senior resident and a junior resident or intern, as well as the respiratory therapist to withdraw the endotracheal tube. No anesthetist or scrub nurse was present for any of the procedures. The procedure took an average of 15 to 25 minutes. Patients were followed for 30 days after surgery to determine the incidence of complications. RESULTS: The incidence of major complications related to the procedure, including hemorrhage and myocardial infarction, was less than 1%. The incidence of minor complications, including moderate bleeding at the tracheotomy site, was 4%. Overall mortality within 30 days was 8%, but was not related to the tracheotomy for any patients in this series. The charge for the procedure was $233 for the tracheotomy tube supplies and instruments. This cost compares favorably with an average charge of more than $3000 for the procedure in the operating room and about $1000 for a percutaneous tracheotomy kit. CONCLUSION: Review of our experience demonstrates that open bedside tracheotomies can be performed more efficiently and economically than operating room tracheotomies. The safety of this procedure is comparable to percutaneous tracheotomy but at a decreased cost.

Tracheotomy in very low birth weight neonates: indications and outcomes.

OBJECTIVE/HYPOTHESIS: To review incidence of, indications for, and outcomes of tracheotomy in very low birth weight (VLBW) infants. STUDY DESIGN: Retrospective review in tertiary care hospital. METHODS: Eighteen VLBW (<1,500 g) infants with bronchopulmonary dysplasia undergoing tracheotomy in the neonatal intensive care unit between October 1997 and June 2002 were studied. Controls consisted of 36 VLBW infants undergoing intubation without tracheotomy, two per study infant, matched by gestational age and weight. Outcome measures included duration and number of intubation events, time to decannulation, complications, comorbidities, length of stay, and speech, language, and swallowing measures. RESULTS: Infants undergoing tracheotomy had an average duration of intubation of 128.8 days with a median number of 11.5 intubation events, both significantly greater than those of controls. Percentage of those with laryngotracheal stenosis was 44% of study infants had laryngotracheal stenosis compared to 1.6% in all intubated VLBW infants. The tracheotomy group had a significantly higher incidence of gastroesophageal reflux, pulmonary hypertension, and gastrostomy tube placement. The overall tracheotomy-related complication rate was 38.9%. Three were lost to follow-up, and five deaths occurred, two possibly tracheotomy-related. Six of ten were decannulated by an average time of 3.8 years, two of six after laryngotracheal reconstruction. Four of ten remained cannulated for a variety of reasons. Disorders of speech, language, and swallowing were common. CONCLUSIONS: When considering tracheotomy in VLBW infants, the total number of intubation events should be monitored as well as the total duration of intubation. The relatively high incidence of laryngotracheal stenosis argues for earlier endoscopy and possibly earlier tracheotomy in infants with developing stenoses.

Prolonged intubation vs. tracheotomy: complications, practical and psychological considerations.

The charts of 52 adult patients who underwent tracheotomy (49 after intubation) were reviewed to identify early complications of both endotracheal intubation and tracheotomy. The complication rate of endotracheal intubation was 57%, and of tracheotomy, 14%. None of the complications of tracheotomy was serious. Sixty critical-care nurses were surveyed about their attitudes regarding prolonged endotracheal intubation and tracheotomy. A large majority preferred tracheotomy for patients who require airway support, for several reasons. First, they felt that tracheotomy patients were more comfortable and, therefore, required less sedation and restraint. Second, the patients could communicate more effectively. Third, airway care was simplified. Ninety-two percent of nurses stated that they would prefer a tracheotomy for themselves or a loved one if more than 10 days of ventilatory support were required. We conclude that tracheotomy can be performed safely in this group of patients, and that it offers significant practical and psychological benefits compared to prolonged endotracheal intubation.

Impact of tracheotomy on colonization and infection of lower airways in children requiring long-term ventilation: a prospective observational cohort study.

STUDY OBJECTIVES: Determination of the following: (1) colonization and infection rates in children requiring long-term ventilation initially via a transtracheal tube and subsequently via a tracheotomy; (2) the number of infection episodes per 1,000 ventilation days, during both types of artificial airways; and (3) routes of colonization/infection of the lower airways, ie, whether the pathogenesis was endogenous (via the oropharynx) or exogenous (via the transtracheal tube or tracheotomy). DESIGN: Observational, cohort, prospective study over 2 1/2 years. SETTING: Pediatric ICU (PICU), Royal Liverpool Children's National Health Service Trust of Alder Hey, a tertiary referral center. PATIENTS: Twenty-two children requiring long-term mechanical ventilation initially transtracheally and subsequently via a tracheotomy. INTERVENTION: Nil. RESULTS: The lower airways were colonized in 71% of children during transtracheal ventilation; posttracheotomy, this was 95% (p=0.03). Children developed significantly fewer infections following colonization with a microorganism posttracheotomy (8/15 pretracheotomy vs 6/21 posttracheotomy; p=0.013). Throughout the study, there were a total of 17 episodes of infection, all of which were preceded by colonization. Haemophilus influenzae, Staphylococcus aureus, Acinetobacter baumannii, and Pseudomonas aeruginosa were the same four causative pathogens during mechanical ventilation both transtracheally and via tracheotomy. Forty-nine episodes of colonization were observed, 15 pretracheotomy and 34 posttracheotomy; of these, 12 (80%) and 19 episodes (56%), respectively, were primary endogenous, ie, present in the oropharynx on hospital admission and subsequently at tracheotomy. Only one colonization episode (7%) of exogenous pathogenesis was observed during transtracheal intubation, while 12 (35%) (p=0.02) occurred after tracheotomy. An equal number of secondary endogenous colonization episodes (two and three, ie, acquired in the oropharynx after PICU admission and after tracheotomy, respectively, were recorded. CONCLUSIONS: (1) Despite a high level of hygiene, exogenous colonization without subsequent infection was common. (2) Although all patients were colonized, the infection rate was lower after tracheotomy. This may be due to enhanced immunity (medically stable) and improved tracheobronchial toilet. (3) Microorganisms in children with tracheotomy differ from those in adults.

Temporary tracheotomy in the surgical treatment of obstructive sleep apnea syndrome: personal experience.

Aim of the study is a retrospective analysis on the use of temporary tracheotomy in our snoring surgery experience. From September 1996 to April 2002, 1103 snoring surgery procedures have been carried out on various sites of the upper airways in 530 patients (mean age 50 years, 81% males) prevalently related to severe Obstructive Sleep Apnea Syndromes (33%). Of these patients, 472 (89%) were operated upon under general anaesthesia, whereas 58 (11%) received local anaesthesia. Of the 472 patients operated upon under general anaesthesia, 17 (3.6%) underwent temporary tracheotomy, which in 10 (2.1%) were programmed and only in 7 (1.5%) were non-programmed, having been performed in 2 cases in an emergency setting, in 3 cases in an urgency setting due to respiratory obstruction immediately after removal of intubation and in 2 cases in conditions of urgency, due to respiratory obstruction occurring during post-operative hospitalisation (both performed within 6 hours of regaining consciousness). The only complication observed was a brief laryngeal diplegia, a complication, moreover, not reported in the literature. No criteria exist concerning indications for temporary tracheotomy programmed according to the type of surgery on the hypopharynx; personal experience reveals that: a) temporary tracheotomy is frequently necessary after genioglossus advancement (3/10 operated upon for genioglossus advancement not associated with a programmed temporary tracheotomy); b) temporary tracheotomy is rarely necessary after hyoid suspension (1/98 patients being submitted to hyoid suspension not associated with programmed temporary tracheotomy). Temporary tracheotomy should, in our opinion, be taken into consideration in snoring surgery techniques, particularly in the presence of the not infrequent urgency or emergency situations occurring in patients with Obstructive Sleep Apnea Syndromes. With the use of temporary tracheotomy, no deaths occurred in the present study population.
