Tracheobronchial rupture due to blunt trauma in children: report of two cases.

Tracheobronchial tree injuries occur in a small number of patients after blunt chest trauma, and their occurrence is uncommon in the pediatric trauma population. The authors report two male children, one with a tracheal rupture, and the other with disruption of the main right bronchus. Mediastinal and subcutaneous emphysema resulting in airway obstruction were noted in Case 1 and soft-tissue emphysema, pneumomediastinum and tension pneumothorax were evident in Case 2 at the time of presentation. In the child with bronchial disruption, a major airway injury was suspected early on, because of a massive air leak despite two properly placed chest tubes. The definitive diagnosis was established bronchoscopically, and thoracotomy and primary repair were performed. The child with rupture of the posterior tracheal wall was diagnosed at an early stage by bronchoscopy and he was successfully managed without surgery.

[Complications of arthroscopy. A review of 3714 cases (author's transl)].

This review is drawn from a total of 3,714 knee arthroscopies carried out on patients from six clinics. The diagnostic value of arthroscopy at this site is established for it can improve prognostication, prevention and treatment of derangements of the knee. The complications of the procedure, both theoretical and in practice, have been considered by subdividing them into four groups. Firstly, the infection rate following arthroscopy alone was nil. Secondly, minor articular cartilage damage attributable to the instrument occurred in just over 2% of cases. This complication is more common when the technique is first being learned and is usually avoidable when experience has been gained. Thirdly, complications of a general nature included four cases of subcutaneous emphysema produced by the insufflation of gas, and 22 instances of an allergic skin reaction to the disinfectant preparation. Finally, failures in the technique itself resulted from the instrument bending or breaking when negotiating the condyles. This occurred on 26 occasions. In a further seven instances the fat pad was entered and distended in error, thus preventing examination of the joint. Overall, the complication rate was acceptable low and confirmed that arthroscopy can be safely applied clinically.

Rabies. A second Australian case, with a long incubation period.

OBJECTIVE: The description of a second case of rabies in Australia, stressing the clinical features and that long incubation periods are possible. CLINICAL FEATURES: A 10-year-old Vietnamese girl presented with fever, shoulder pain, subcutaneous emphysema, swallowing difficulty and agitation. After a period of maniacal behaviour all peripheral and central nervous system function was lost. INTERVENTION AND OUTCOME: Despite maximal intensive care, the patient died. The diagnosis of rabies was made at autopsy. CONCLUSIONS: Rabies occurs in Australia and needs to be considered in the differential diagnosis of acute encephalitis and/or the Guillain-Barré syndrome. Incubation periods of more than six years can occur.

Postoperative tracheal rupture in a patient with a difficult airway.

PURPOSE: Tracheal rupture is an uncommon and potentially life-threatening event. This report presents a case of postoperative tracheal rupture in a patient with a known difficult airway presenting to a rural hospital. CLINICAL FEATURES: A 29-yr-old man presented to a rural hospital with sudden onset neck pain and progressive dyspnea. Five days earlier the patient had undergone tracheal resection for tracheal stenosis related to prolonged intubation. The patient informed the emergency room staff that the attending anesthesiologist had made note of a "difficult airway". The community hospital had neither a portable storage unit for difficult airway management nor a bronchoscope available. In the presence of a general surgeon, an initial attempt at an awake intubation was unsuccessful. During this time the patient developed massive subcutaneous emphysema obliterating surgical landmarks and causing stridor. A modified rapid sequence intubation was performed. Intubation was successful using a Jackson-Wisconsin #3 straight blade and styletted endotracheal tube. The patient was transferred to a tertiary care centre where he underwent a primary repair of the trachea. CONCLUSION: Management of tracheal rupture in the patient with a difficult airway is a challenging problem, especially, in a rural hospital. This case highlights the need for skilled staff and resources to manage a difficult airway in the emergency room.

CT findings after uncomplicated percutaneous laparoscopic cholecystectomy.

To investigate the postoperative pulmonary and abdominal findings following uncomplicated percutaneous laparoscopic cholecystectomy, 27 patients were studied by upper abdominal CT within 24 h of the surgical procedure. Both pneumoperitoneum (70%) and subcutaneous emphysema (56%) were commonly observed. Postoperative atelectasis and pleural effusions were observed in 44 and 33% of the patients, respectively. Forty-eight percent of the patients had a postoperative ileus demonstrated by CT. Approximately 22% of the patients had fluid in the abdomen as either edema in the gallbladder fossa or small amounts of ascites. In our patients the amount of ascitic fluid was small and no clinical significance could be attributed to the intraabdominal fluid collections.

Fiberoptic bronchoscopy in the evaluation of acute chest and upper airway trauma.

To determine the utility of fiberoptic bronchoscopy (FFB) in the short-term evaluation of patients with trauma, we identified 53 consecutive patients (45 male patients; mean age, 36 years) seen over a ten-year period who had FFB performed within the first three days of trauma to the chest and upper airway. There were eight deaths. Fifty patients had blunt trauma to the chest. These were mostly due to motor vehicle accidents (38 patients), crushing injuries (three patients), and falls (three patients). In addition, there were three patients with trauma to the neck. Physical and radiographic findings included pneumothorax (37 patients), subcutaneous emphysema (31), pulmonary contusion (22), hemothorax (21), mediastinal emphysema (16), flail chest (ten), atelectasis (ten), and hemoptysis (five). The FFB was of diagnostic use in 28 patients (53 percent) by revealing complete tracheal transection (one patient), tracheal laceration (three), complete bronchial transection (one), bronchial laceration (two), bronchial contusion (two), ongoing distal hemorrhage/pulmonary contusion (seven), aspirated material (three), mucous plugging/thick secretions (eight), and supraglottic lesions (three). One of the cases of tracheal laceration was not fully appreciated as a complete transection. We conclude that FFB has value in the short-term evaluation of patients with trauma.

Minitracheotomy: complications and follow-up with fibreoptic tracheoscopy.

Complications and changes in tracheal mucosa after minitracheotomy were evaluated in 28 patients. Tracheal mucosa was inspected fibreoptically after the insertion of a minitracheotomy cannula, and then at 3-day intervals until the cannula was removed. Thereafter, assessments were made every third day until the mucosa was considered normal. Three significant complications occurred: mediastinal puncture, paratracheal entrance of the cannula and subcutaneous emphysema. Difficulties at insertion of the minitracheotomy cannula were encountered in 15 of 28 patients (54%). Air flow detected through the cannula in one patient, and lack of air flow in another patient, were misleading signs of the position of the cannula. Passing a suction catheter in three patients and a normal end-tidal carbon dioxide tracing in one patient, were also found to be misleading. The correct position and possible complications could be verified only by fibreoptic tracheoscopy. Changes in the tracheal mucosa were independent of the duration of minitracheotomy therapy.

Transtracheal high frequency jet ventilation for endoscopic airway surgery: a multicentre study.

Serious complications during high frequency jet ventilation (HFJV) are rare and have been documented in animals and in case reports or short series of patients with a difficult airway. We report complications of transtracheal HFFJV in a prospective multicentre study of 643 patients having laryngoscopy or laryngeal laser surgery. A transtracheal catheter could not be inserted in two patients (0.3%). Subcutaneous emphysema (8.4%) was more frequent after multiple tracheal punctures. There were seven pneumothoraces (1%), two after laser damage to the injector, one after difficult laryngoscopy, four with no clear cause. Arterial desaturation of oxygen was more frequent during laser surgery and in overweight patients. Transtracheal ventilation from a ventilator with an automatic cut-off device is a reliable method for experienced users. Control of airway pressure does not prevent a low frequency of pneumothorax.

[Working conditions and complications during laryngomicroscopies under endotracheal ventilation via intubation tubes or injection ventilation].

During a period of 7 years 693 laryngomicroscopies (LAR) were performed on 490 patients. General anaesthesia was given by 21 anaesthesists: 5 applied ventilation only through a conventional intubation tube. Of the remaining 16 anaesthesists, 8 constantly prefered, 4 used occasionally jet ventilation (JET), and 4 applied both methods alternatively. No rationale was found for this choice. Laryngomicroscopies were performed by 14 ENT surgeons. One case of subcutaneous emphysema and two of pneumothorax were obtained with JET, obviously because of inexperience and neglect of precautions. Two epidermoid carcinomas in the left posterior commissure escaped the primary LAR, most probably because of poor vision due to the intubation tube, and were found during subsequent procedures with JET. In spite of the risk of complications (mostly avoidable with care and increasing experience), the main advantage of JET is the better chance of revealing of carcinoma in an earlier phase, when it is more amenable to curative therapy. Therefore, we no longer recommend ventilation through an intubation tube for laryngomicroscopies, but prefer intratracheal jet-ventilation for this purpose.

[Mediastinal emphysema in children].

A review of 25 infants developing pneumediastinum and subcutaneous emphysema was done. These observations suggested that increasing airways presure creates excessive alveolar distention. Pulmonary interstitial emphysema results from movement of air out of alveoli into interstitial areas. From this point air could dissect along the perivascular or interstitial spaces to the mediastinum.

[Results of endoscopically controlled dacryocystorhinostomies].

The results of 104 endoscopically controlled dacryocystorhinostomies performed in 93 patients from June 1989 to June 1993 are presented. Postoperatively, 38 patients had a hematoma, 12 a subcutaneous emphysema and three patients an intraorbital emphysema. All complications were transitory. On 89 sides (85.57%) dacryorrhea was completely cured, on ten sides (9.61%) it was eased considerably, and it was not resolved in five cases, of whom, two had been operated through an external approach previously. A closed postoperative care is important in order to achieve good results. In 25.6% of the cases, the anterior ethmoid displayed patterns of a chronic inflammation. Its involvement in the pathogenesis of chronic dacrocystitis has to be discussed. In many cases, the localisation of the lacrimal gland is more posteriorly than described in anatomy leading to an impeded drainage and subsequently to dacryoadenitis. In our hands, the endoscopically controlled dacryocystorhinostomy presents as a save approach and a good alternative to the procedure described by Toti.

[Echography of pneumothorax].

Ultrasound of 28 radiologically confirmed cases of pneumothorax were compared to 100 controls. Specific ultrasonographic signs were shown in all cases and could be categorised into four groups: isolated pneumothorax (n = 16), hydro-pneumothorax (n = 9), subcutaneous emphysema (n = 1) and post aspiration pneumothorax (n = 2). The isolated pneumothorax was characterised by the disappearance of the lung deflection signal. The effusion of the hydropneumothorax allows in addition a curtain sign which depicts the movement of the air/fluid level, the detachment of the lung being calculated across the liquid window whose echo-structure is analysed. Pneumothoraces appearing during an echo guided thoracic puncture are confirmed by the disappearance of the pathological image. Thus echography appears to be a new method in the diagnosis of pneumothoraces and is complimentary to standard radiology. It should be confirmed as particularly useful during the process of thoracic puncture or juxta-diaphragmatic puncture when following the process of a pneumothorax, for emergency situations and/or those in which no radiological equipment is available.

Complications of laser surgery for laryngeal papillomatosis.

Carbon dioxide laser surgery has become the treatment of choice for laryngeal papillomatosis. The purpose of this study was to determine the type, incidence, and severity of complications that occur with laser microlaryngoscopy for a disease that often requires multiple operations. Forty patients with laryngeal papillomatosis underwent a total of 222 carbon dioxide laser laryngoscopies over the 6 1/2-year period from June 1977 through December 1983. The results showed that 13 patients sustained a total of 23 separate complications. Intraoperative complications consisted of one episode of bilateral pneumothorax and one episode of cervical subcutaneous emphysema, both associated with the use of jet ventilation anesthesia, and one episode of a loosened tooth in a child with carious teeth. The delayed complications consisted of 10 patients with anterior laryngeal webbing, 2 patients with posterior webbing, 6 patients with laryngeal edema or fibrosis, and one episode each of prolonged dysphagia and tracheal foreign body. No airway fires occurred. Only 2 of 28 patients who had 5 or fewer laser laryngoscopies developed complications, but 11 or 12 patients undergoing 6 or more laser operations had complications. In summary, although the incidence of life threatening complications was low, the occurrence of minor complications such as small anterior glottic webs and persistent edema was relatively high, especially in those patients who required multiple laser laryngoscopies.

[Deleterious effects of mechanical ventilation on the lower lung].

Mechanical ventilation may have adverse effects on the lung. The appearance of extra-alveolar air, either as a pneumothorax or as subcutaneous emphysema along with other manifestations, is a complication of barotrauma which has been known for a long time. Recent experimental studies have clearly shown that mechanical ventilation can also lead to alterations in the blood gas barrier. Mechanical ventilation with high inflation pressure and elevated tidal volumes induces pulmonary oedema; the genesis of which results principally from anomalies of alveolar capillary permeability. These anomalies are made as a result of pulmonary distension and not as a result of elevated pressures in the airways, thus justifying the term "volume traumatism". The existence of previous acute pulmonary injury considerably worsens the deleterious pulmonary effect of mechanical ventilation. Although the direct clinical implications of these experimental studies are difficult to confirm, these latter have nevertheless lead to profound changes in ventilatory strategy during the course of acute pulmonary disease such as the adult respiratory distress syndrome.

Post-traumatic bronchial stenosis and acute respiratory insufficiency.

A 31-year-old woman sustained multiple injuries, including severe contusion of the right lung with massive subcutaneous emphysema. Four weeks later she was transferred to our institution with post-traumatic adult respiratory distress syndrome and carbon dioxide retention, resulting from a postlaceration stenosis of the left main-stem bronchus. Bronchoplasty was contraindicated because of the serious condition of the patient. Repeated bronchial dilatations produced initial improvement in oxygenation and minute ventilation requirements. However, because of the nature of the stenosis and the lack of recovery of right lung function, the patient's encouraging clinical course reached a plateau and attempts at weaning from the respirator were unsuccessful. Bronchoplasty was performed on postadmission day 50 and resulted in gradual recovery of pulmonary function. Six months following discharge, the patient continues a steady improvement. Management of the patient's injuries represented a unique challenge previously unencountered.

Laryngotracheal disruption from blunt pediatric neck injuries: impact of early recognition and intervention on outcome.

Blunt and penetrating neck injuries are an infrequent cause of morbidity and mortality in the pediatric population. Although less common than penetrating injuries, blunt pediatric neck injuries are more often life-threatening because of associated laryngotracheal disruption. The authors reviewed their experience with pediatric neck injuries over the past 5 years. There were nine blunt and 14 penetrating injuries, representing 0.5% of the trauma admissions. There was no significant difference in age or gender distribution between the two groups. Blunt pediatric neck injuries were more often associated with frank respiratory distress at the time of presentation. Massive subcutaneous emphysema and hoarseness were the most common symptoms encountered. All patients with blunt injury underwent direct laryngoscopy and bronchoscopy (DL & B) and esophagoscopy. DL & B results were positive for eight patients; seven patients underwent neck exploration and successful repair of the laryngotracheal injuries. There were two deaths; one of these patients had laryngeal transection, which was not recognized at the time of DL & B. The other death resulted from associated tracheobronchial disruption secondary to massive blunt chest trauma. The patients with penetrating neck injuries were more likely to be treated nonoperatively, to have a shorter stay in the hospital and intensive care unit, and to have a lower injury severity score. There were no deaths in this group. The authors conclude that all patients with blunt neck trauma should undergo emergent and meticulous DL & B. Visualization of laryngotracheal disruption mandates immediate neck exploration and primary repair.

Role of Spiral and Multislice Computed Tomography in the evaluation of traumatic and spontaneous oesophageal perforation. Our experience.

PURPOSE: To assess the role CT in the evaluation of traumatic and spontaneous oesophageal perforation. MATERIALS AND METHODS: From March 2001 to May 2003, we studied 12 patients (7 males and 5 females; age range: 25-66 years, mean age: 43.5 years) with suspected oesophageal perforation due to motor-vehicle accidents (4 cases), stab wound (one case), post-intubation (2 cases), foreign body ingestion (2 cases) and spontaneous (3 cases). Five patients underwent standard chest and cervical radiography; two patients with suspected foreign body ingestion also underwent a gastrografin swallow study; all of the 12 patients underwent CT of the neck, chest and abdomen before and after intravenous, and in four cases oral, administration of contrast material. RESULTS: In 5 patients with cervical, thoracic and abdominal trauma, the CT examination showed the presence of pleuroparenchymal injury (pneumothorax, pleural effusion and subcutaneous emphysema) as well as findings suggestive of oesophageal perforation: peri-oesophageal air (5 cases), peri-oesophageal fluid (4 cases), oesophageal wall thickening (3 cases), oesophageal wall laceration (2 cases) with abnormal course of the nasogastric tube in one of them and extraluminal extravasation of oral contrast material (2 cases). In 2 patients with post-intubation complications, CT showed the presence of a small peri-oesophageal fluid collection containing small gas bubbles in one case, and a gross perioesophageal abscess-like collection in the second case. In the 2 patients with foreign body ingestion, the plain radiography associated with CT showed the presence of a thin metal object in the cervical region (fragment of a dental plate) and a small extraluminal extravasation of gastrografin in one case, whereas in the other case CT showed the presence of a foreign body (chicken bone) in the hypopharynx with oesophageal wall thickening and peri-oesophageal oedema. In the remaining three patients with suspected spontaneous oesophageal perforation, CT showed the presence of a intramural haematoma in one case, oesophageal fluid distension with gas and a small peri-oesophageal fluid effusion (Mallory-Weiss syndrome) in another, and oesophageal rupture (Boerhaave syndrome) in the last case. CONCLUSIONS: Our experience shows that in patients with suspected traumatic and spontaneous oesophageal perforation, standard cervical and chest radiography may suggest a suspected oesophageal perforation in only a small proportion of cases, whereas oral contrast oesophagography has a higher sensitivity. Through the careful analysis of suggestive and specific signs of oesophageal perforation, a correct CT examination enables an accurate and timely diagnosis which significantly affects prognosis and provides valuable indications for treatment.
