Directional-tip endotracheal tubes for blind nasotracheal intubation.

OBJECTIVES: To compare initial success rates of blind nasotracheal intubation using directional-tip endotracheal tubes vs standard endotracheal tubes. METHODS: A prospective trial comparing directional-tip and standard endotracheal tubes during initial attempts at blind nasotracheal intubation (BNTI) at a university hospital ED. Using an alternating schedule, the directional-tip or standard tube was used for the first attempt at BNT1. An attempt was defined as beginning when the tube was placed through the nose into the posterior pharynx and ending when the patient was intubated or the tube was removed from the nares. After the intubation, the physician graded the difficulty of the technique (i.e., easy/routine, intermediate, difficult, or unable to intubate nasally). RESULTS: There were 49 patients entered over 5 months. Patient presentations for the intubations were trauma (45.8%), overdose (33.3%), respiratory/cardiac event (12.5%), seizure (2.1%), and other (6.3%). Intubation was successful on the first attempt in 18 of 21 patients (86%; 95% CI, 64% to 97%) for the directional-tip tube vs 16 of 28 patients (57%; 95% CI, 37% to 76%) for the standard tube (p = 0.03). The groups did not differ in age, sex, clinical presentation, or perceived difficulty of intubation. Only 1 patient could not be intubated nasally and was subsequently intubated orally. CONCLUSION: The use of directional-tip tubes may improve the success rate of the first attempt at BNTI.

Initial experience of emergency physicians using the intubating laryngeal mask airway: a case series.

OBJECTIVE: Although the intubating laryngeal mask airway (ILMA) is widely available, its use by emergency physicians (EPs) has not been reported. The authors report the initial experience of EPs using the ILMA. A review of their experience and the relevant anesthesia literature provides a basis for EPs to use the ILMA more confidently and effectively. METHODS: Between January 2000 and January 2001, the ILMA was used on a convenience sample of emergency department (ED) patients undergoing "routine" intubations, and "rescue" situations, after failed rapid-sequence intubation (RSI). Patients were identified from the ED resuscitation case database. Chart review and intubating physician interviews focused on success of the device, complications encountered, and "pearls" of the device's use as perceived by the intubating physician. RESULTS: Ventilation with the appropriate-size ILMA occurred in less than 15 seconds in all "routine" intubations; tracheal intubation was subsequently accomplished in less than 1 minute. Eight of nine "routine" patients had blind tracheal intubation through the ILMA. One patient required fiberoptic bronchoscopy to guide the endotracheal tube into the trachea. Of the "rescue" intubations, all patients (n = 7) were successfully ventilated and five were successfully intubated using the ILMA. CONCLUSIONS: In this case series, the ILMA was easy to use in acute resuscitations, and proved to be invaluable in cases of failed RSI.

Paramedic intubation of patients with severe head injury: a review of current Australian practice and recommendations for change.

Secondary brain injury may occur early after severe traumatic brain injury due to hypoxia and/or hypotension. Prehospital care by ambulance paramedics has the goal of preventing and treating these complications and, thus, improving outcomes. In Australia, most ambulance services recommend paramedics attempt endotracheal intubation in patients with severe head injury. Even though most patients with severe head injury retain airway reflexes, most states do not allow the use of appropriate drugs to facilitate intubation. In contrast, recent evidence from trauma registries suggests that this approach may be associated with significantly worse outcomes compared with no intubation. Two states allow intubation facilitated by sedative (but not relaxant) drugs, but this has a low success rate and could worsen brain injury because of a decrease in cerebral perfusion pressure. For road-based paramedics, the role of rapid sequence intubation is uncertain. Given the risks of this procedure and the lack of proven benefit, this procedure should not be introduced without supportive evidence from randomised, controlled trials. In contrast, for safety reasons, comatose patients transported by helicopter should undergo rapid sequence intubation prior to flight. However, this is not authorised in most states, despite good supportive evidence that this can be safely and effectively undertaken by paramedics. Finally, there is evidence that inadvertent hyperventilation is associated with adverse outcome, yet only two ambulance services use waveform capnography in head injury patients who are intubated. Overall, current paramedic airway practice in most states of Australia is not supported by the evidence and is probably associated with worse patient outcomes after severe head injury. For road-based paramedics, rapid transport to hospital without intubation should be regarded as the current standard of care. Rapid sequence intubation should be limited to use within appropriate clinical trials, or patients transported by helicopter. For patients who are intubated, waveform capnography is essential to confirm tracheal placement and to prevent inadvertent hyperventilation.

Emergency intubation of infants: does laryngoscope blade design make any difference?

OBJECTIVE: To compare intubation times and ease of use for a range of infant laryngoscope blades in the hands of accident and emergency (A&E) personnel. METHODS: Seven different blades were compared in terms of intubation times and ease of use scores in the hands of 30 A&E senior house officers (SHOs) and nurses using a standard infant manikin. RESULTS: There was a significant difference in intubation times between the seven blades (p < 0.001). Intubation with two blade designs (Seward and Soper) took almost twice as long as for the other blades (p < 0.05). Subjective ease of use scoring also identified the Seward and Soper blades as being the most difficult to use (p < 0.05). There were no significant differences between SHO and nurse intubation times or ease of use scoring. Successful intubation was achieved within 30 seconds in 90% of attempts. All but two of the subjects used an incorrect levering technique for intubation despite all having previously received training in infant intubation. CONCLUSIONS: No current standard exists regarding the utilisation of infant laryngoscope blades in the A&E department. The first line blade available should be a C shaped blade (Miller, Oxford, Robert-shaw, or Wisconsin). Other blade designs should be kept for use only by more experienced personnel or in difficult intubation situations. Intubation training must focus on correct technique and regular assessment is essential.

Randomised controlled trial of thiopental for intubation in neonates.

AIMS: To determine the effects of premedication with thiopental on heart rate, blood pressure, and oxygen saturation during semi-elective nasotracheal intubation in neonates. METHODS: A randomised, placebo controlled, non-blinded study design was used to study 30 neonates (mean birthweight 3.27 kg) requiring semi-elective nasotracheal intubation. The babies were randomly allocated to receive either 6 mg/kg of thiopental (study group) or an equivalent volume of physiological saline (control group) one minute before the start of the procedure. Six infants were intubated primarily and 24 were changed from orotracheal to a nasotracheal tube. The electrocardiogram, arterial pressure wave, and transcutaneous oxygen saturation were recorded continuously 10 minutes before, during, and 20 minutes after intubation. Minute by minute measurements of heart rate, heart rate variability, mean blood pressure (MBP) and transcutaneous oxygen saturation (SpO(2)) were computed. The differences for all of these between the baseline measurements and those made during and after intubation were determined. Differences in the measurements made in the study and the control groups were compared using Student's t test. RESULTS: During intubation, heart rate increased to a greater degree (12.0 vs -0.5 beats per minute, p < 0.03) and MBP increased to a lesser degree (-2.9 vs 4.4 mm Hg; p < 0.002) in the infants who were premedicated with thiopental. After intubation only the changes in MBP differed significantly between the two groups (-3.8 vs 4.6 mm Hg; p < 0.001). There were no significant changes in the oxygen saturation between the two groups during or after intubation. The time taken for intubation was significantly shorter in the study group (p < 0.04). CONCLUSIONS: The heart rate and blood pressure of infants who are premedicated with thiopental are maintained nearer to baseline values than those of similar infants who receive no premedication. Whether this lessening of the acute drop in the heart rate and increase in blood pressure typically seen during intubation of unmedicated infants is associated with long term advantages to the infants remains to be determined.

Histopathologic changes in laryngeal mucosa of extremely low-birth weight infants after endotracheal intubation.

OBJECTIVES: Advances in medicine have improved the survival of infants with increasingly lower birth weights. The histopathologic changes of intubation-related laryngeal injury in extremely low-birth weight infants (less than 1,000 g) have not been well known. We examined histopathologic changes in infant larynges, including extremely low-birth weight infants, after endotracheal intubation. METHODS: Forty-four infants, including 21 extremely low-birth weight infants, who had been intubated for periods ranging from 10 minutes to 138 days, were examined in a whole organ serial section study. RESULTS: As the duration of intubation increased, the ulceration was found to be larger and deeper. The injury at the subglottis and posterior glottis was greater than that at other portions. The perichondrium of the cartilage was exposed in many cases intubated longer than 8 days. Repaired epithelium that was composed of squamous epithelium was present in 6 of 7 larynges that had been intubated more than 20 days, indicating that not only injury but also the healing process occurred during long intubation. There were no obvious relationships between the degree of intubation injury and the birth weight of the infants. CONCLUSIONS: Prolonged intubation is better tolerated by infants than adults. The intubation-related laryngeal injuries of extremely low-birth weight infants were histopathologically the same as those of infants of other birth weights.

Intubating laryngeal mask airway.

The Intubating Laryngeal Mask Airway (ILMA) was introduced into clinical practice in 1997 following numerous clinical trials involving 1110 patients. The success rate of blind intubation via the device after two attempts is 88% in "routine" cases. Successful intubation in a variety of difficult airway scenarios, including awake intubation, has been described, with the overall success rate in the 377 patients reported being approximately 98%. The use of the ILMA by the novice operator has also been investigated with conflicting reports as to its suitability for emergency intubation in this setting. Blind versus visualized intubation techniques have also been investigated. These techniques may provide some benefits in improved safety and success rates, although the evidence is not definitive. The use of a visualizing technique is recommended, especially whilst experience with intubation via the ILMA is being gained. The risk of oesophageal intubation is reported as 5% and one death has been described secondary to the complications of oesophageal perforation during blind intubation. Morbidity described with the use of the ILMA includes sore throat, hoarse voice and epiglottic oedema. Haemodynamic changes associated with intubation via the ILMA are of minimal clinical consequence. The ILMA is a valuable adjunct to the airway management armamentarium, especially in cases of difficult airway management. Success with the device is more likely if the head of the patient is maintained in the neutral position, when the operator has practised at least 20 previous insertions and when the accompanying lubricated armoured tube is used.

Remifentanil with thiopental for tracheal intubation without muscle relaxants.

UNLABELLED: Tracheal intubation may be accomplished with remifentanil and a non-opioid IV anesthetic without a muscle relaxant. In this study, we evaluated in double-blinded, prospective, randomized manner the dose requirements for remifentanil with thiopental without muscle relaxant administration to obtain clinically acceptable intubation conditions and cardiovascular responses. After premedication with midazolam 0.03 mg/kg IV, 105 patients were randomized equally to one of three study groups, each receiving the following: remifentanil 2 micro g/kg (Group I), 3 micro g/kg (Group II), and 4 micro g/kg (Group III). Remifentanil was administered over 30 s, and anesthesia was induced with thiopental 5 mg/kg. Tracheal intubation conditions were assessed by the anesthesiologist performing the intubation as: (a) excellent, (b) satisfactory, (c) fair, and (d) unsatisfactory. There were no statistically significant differences among groups regarding to demographic data. Blood pressure and heart rate did not increase in any group after accomplishing intubation. There was a significant improvement in intubation conditions between Groups I and II, I and III, and II and III (P < 0.001). We conclude that remifentanil 4 micro g/kg administered before thiopental 5 mg/kg provided excellent or satisfactory intubation conditions in 94% of patients and prevented cardiovascular responses to intubation. IMPLICATIONS: We evaluated in a double-blinded manner the dose requirements for remifentanil with thiopental without muscle relaxants for obtaining acceptable intubation condition. Our results show that remifentanil 4 micro g/kg administered before thiopental provided excellent or satisfactory intubation condition in 94% of patients.

Training and evaluation of respiratory therapists in emergency intubation.

Endotracheal intubation in emergency situations is a recognized function of respiratory therapists, as defined by the American Association for Respiratory Therapy in 1973. A training program based in the operating room, using one-on-one instruction, was the basis for a training program designed to meet JCAH standards for endotracheal intubation. To evaluate the success of our training and our system for attempting intubations, we recorded the results of 50 consecutive intubation attempts by our therapists. All 50 patients were eventually intubated, with 35 patients intubated on the first attempt. The average number of attempts per patient was 1.48. While 39 patients were intubated within one minute, 11 required more than one minute. In five patients, physicians had attempted intubation prior to a therapist's arrival; those intubations took eleven times longer than those that were attempted by therapists only. The average time for intubations attempted solely by therapists was 54 seconds.

Recertification of respiratory therapists' intubation skills one year after initial training: an analysis of skill retention and retraining.

Allied health personnel and nonanesthesiologist physicians often undergo training in tracheal intubation but then may actually use the skill relatively infrequently. This study assessed retention of skills one year after initial training and identified specific areas of knowledge critical to successful performance of intubation. Eleven respiratory therapists on the staff of a 253-bed hospital, each of whom had been trained one year previously in airway management, were evaluated. Prior to returning to the operating room for skills assessment and recertification, each respiratory therapist took a 21-question written exam. Therapists then went to the operating room and a trained observer (anesthesiologist) monitored the intubations performed to see whether critical steps were followed, while a second observer monitored a checklist of skills performed. The attending anesthesiologist recertified the therapist only when all steps were correctly performed and the intubation was successful. There was a poor correlation (r = -0.25, p > 0.1) between the number of intubations performed by the therapists for emergencies in the previous year and the number of intubations needed to be recertified. There was a negative correlation (r = -0.8, p < 0.05) between the score on the written test and the number of intubations required for recertification-a higher score meant fewer intubations were needed to achieve recertification. First-pass success occurred significantly more frequently if all skills tested were performed correctly (50/75 first-pass successes had all skills performed correctly vs 10/28 for failed first-pass, p < 0.01). The most common errors were levering the blade on the upper teeth (12/91) and tube not inserted from the right side of the mouth (28/104). When the blade was levered, 8 of 10 intubations failed. When the tube was not inserted from the right side of the face, 6 of 12 failed. The useful findings of this study are: (1) occasional performance of intubation did not ensure skill maintenance; (2) cognitive and procedural abilities correlated, suggesting benefits to study as well as to practical training; and (3) two specific mistakes were associated with a high incidence of failure.

Protocol for rapid sequence intubation in pediatric patients -- a four-year study.

BACKGROUND: To evaluate a protocol for rapid sequence intubation (RSI) for pediatric patients in a Level 1 trauma center. MATERIAL/METHODS: Retrospective review of prospectively gathered Continuing Quality Improvement (CQI) data at an inner city Level 1 trauma center with an emergency medicine residency program. Protocols for RSI were established prior to initiating the study. All pediatric intubations at the center from February 1996 to February 2000 were included. Statistical analysis included descriptive statistics for categorical data and Chi-square for comparisons between groups. RESULTS: Over the 4-year study period there were 83 pediatric intubations ranging in age from 18 months to 17 years; mean age 8.6. All had data collected at the time of intubation. There were 20 (24%) females and 62 (76%) males (p<0.001). Reasons for intubation were related to trauma in 71 (86%) and medical reasons in 12 (14%) (p<0.001). Of the trauma intubations 7 (10%) were for gunshot wounds, 39 (55%) were secondary to MVCs, and the remainder (25; 35%) were from assaults, falls, and closed head injuries. The non-trauma intubations were for smoke inhalation, overdose, seizure, HIV related complications, eclampsia, and near drowning. Intubations were successful with one attempt in 65 (78%) cases. No surgical airways were necessary. Rocuronium was used in 4 cases. Protocol deviations did not lead to complications. CONCLUSIONS: This protocol based pediatric rapid sequence intubation method worked well in an EM residency program. More intubations were in males and more were necessary due to trauma in this group.

[Seriously injured patients intubated at the accident site. A three-year survey from the mobile emergency care unit in Aarhus].

BACKGROUND: The success rate of out-of-hospital endotracheal intubations performed by paramedics has been questioned. It seems to be difficult to achieve and keep a routine. The aim was to describe the severity of injuries and the number of such intubations in trauma patients treated by the Mobile Emergency Care Unit (MECU) staffed with an anaesthetist. MATERIALS AND METHODS: The case records of all trauma patients on whom the MECU, Arhus, performed endotracheal intubation at the accident site from 1 May 1997 to 30 April 2000 were studied. Lesions were classified according to the abbreviated injury scale (AIS), and the injury severity scores (ISS) were calculated. Severe injury was defined as an ISS > 15. RESULTS: Over the three-year period the MECU attended 2546 trauma patients, 95 (3.7%) of whom were intubated at the site. In one case, endotracheal intubation was not possible and cricothyrotomy had to be performed. Of the patients intubated at the site 65 had an ISS > 15. This, according to previous studies, corresponded to about 20% of all severely injured patients arriving at our hospital. Sixty patients had severe lesions in the head region. In sixty-eight cases (72%) endotracheal intubation was preceded by anaesthesia. DISCUSSION: Out-of-hospital endotracheal intubation of trauma patients was not a frequent intervention, as compared to all emergency calls, but it was relatively frequent in the severely injured brought to our hospital. If endotracheal intubation is to be one of the available interventions in the prehospital setting, this study confirms that it should preferably be done by physicians experienced in intubation and anaesthesia.

Effectiveness of lightwand (Trachlight) intubation by 1st year anesthesia residents.

Transillumination of the soft tissue of the neck using a lighted stylet (lightwand) is an effective and safe intubating technique in experienced hands. The goal of this study was to determine the effectiveness and safety of this device in intubating the trachea of elective surgical patients by non-experienced hands. One hundred and fifty, paralysed, anesthetized, adult patients (ASA I-II, no known or potential problems with intubation) were studied. Failure to intubate was defined as lack of successful intubation after three attempts. The duration of each attempt was recorded as the time from insertion of the device into the oropharynx to the time of its removal. The total time to intubation (TTI) was defined as the sum of the durations of all (as many as three) intubation attempts. Complications, such as mucosal bleeding, lacerations, dental injury and sore throat were recorded. The mean TTI was 42.0 +/- 34.3 seconds. The overall intubation success rate was 92 per cent. Of all the successful intubations, 87.68 per cent were successful after one attempt. There were significantly fewer traumatic events (5.33%). Most of the trauma consisted of minor mucosal bleeding or mucosal laceration. We conclude that lightwand intubation is an effective and safe technique in non-experienced hands.

Fibre-optic awake intubation for caesarean section in a parturient with predicted difficult airway.

Anaesthetic management of a parturient with predicted difficult airway presenting for caesarean section (CS) is not a straightforward decision: general anaesthesia should be avoided because intubation can be impossible and a "cannot intubate, cannot ventilate" scenario might ensue, on the other hand regional techniques can be unsuccessful or, though rarely, have complications that require emergency intubation. The case is presented of a primigravida admitted to hospital at 37 weeks' gestation with hypertension, intrauterine growth retardation and oligohydramnios. After a few days' observation, it was decided to proceed with an elective CS. The preoperative airway examination revealed a poor mouth opening with an interdental distance of 20 mm and a Mallampati class IV. The patient was classified as a case of difficult intubation and the following anaesthetic options were considered: epidural anaesthesia, spinal anaesthesia and awake fibreoptic intubation followed by general anaesthesia. The pros and the cons of these techniques were explained to the patient and it was suggested that awake fibreoptic intubation was the safest option. The patient gave her consent, so an uneventful nasal awake fibreoptic intubation was carried out under local anaesthesia. This case report offers the opportunity to underline the risk to perform a central blockade in a parturient with predicted difficult intubation, arguing that the safest course of action is an awake fibrescopic intubation, besides some controversial points to safely perform awake fibreoptic intubation in obstetric patients are discussed.

Effects of alfentanil and esmolol on hemodynamic and catecholamine response to tracheal intubation.

OBJECTIVE: To compare the effects of alfentanil and esmolol on hemodynamic and catecholamine response to tracheal intubation. METHODS: Thirty-five adult patients were randomly allocated to one of three groups, Group A (control group). Group B (esmolol group) and Group C (alfentanil group). The patients received either 2 mg/kg esmolol (in Group B) or 30 microg/kg alfentanil (in Group C) before intubation. Tracheal intubation was performed with 4 mg/kg thiopental and 0.1 mg/kg vecuronium and 3% isoflurane. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean blood pressure (MBP), heart rate (HR), norepinephrine (NE), epinephrine (E) and dopamine (DA) were measured before and after intubation. RESULTS: The control group had a baseline SBP of 149 +/- 23 mmHg while Groups B, C had a baseline SBP of 148 +/- 23, and 150 +/- 21 mmHg, respectively (P>0.05). Three min after tracheal intubation, the control group SBP increased to 160 +/- 30 mmHg and Group B remained at the baseline level, 147 +/- 5 mmHg, and Group C significantly decreased to 91 +/- 22 mmHg (P<0.01). Two min after intubation HR in Group B increased significantly but 3 min after intubation HR in Groups B and C were significantly lower than that of control group (P<0.05). NE in Groups A and B increased significantly to 5.75 +/- 3.51 and 6.75 +/- 3.30 nmol/L 3 min after intubation (P<0.01). In Group C, 3 min after intubation NE was not significantly different from the baseline but E decreased significantly (P<0.01). CONCLUSION: 2 mg/kg esmolol can moderate the hemodynamic response to tracheal intubation to a certain extent and 30 microg/kg alfentanil can completely attenuate the hemodynamic and catecholamine responses.

[Comparison of emergency tracheal intubation performed on a table and on the ground].

BACKGROUND: Emergency tracheal intubation in the pre-hospital environment is generally more difficult than when performed at a hospital. Among the reasons making it more challenging, is the rescuer's position. We compared tracheal intubation between 2 settings, on a table and on the ground. METHODS: Ten staff anesthesiologists were asked to intubate mannequins placed on a table and on the ground. Measured variables included intubation time, Cormack grade, incidence of esophageal intubation, "crick" sound from the teeth of the mannequin, and degree of head tilt during intubation attempts. RESULTS: Mean intubation times on the table and ground were 12.6 +/- 3.9 and 14.7 +/- 6.5 seconds, respectively. No esophageal intubation occurred. Cormack grades and incidence of teeth click were significantly higher on the floor, whereas there was no difference regarding degree of head tilt between the 2 settings. CONCLUSIONS: Our results indicate that intubation on the ground is more difficult and may require a longer time to accomplish, even for experienced anesthesiologists. Therefore, those involved in airway management training for emergency personnel should acquire appropriate skills to teach tracheal intubation in such a difficult situation.

The role of anesthetic induction agents and neuromuscular blockade in the endotracheal intubation of trauma victims.

Management of extensive trauma often requires immediate tracheal intubation and mechanical ventilation. The role of anesthetic induction agents and neuromuscular blockade in the airway management of the trauma victim is disputed. To better define the role of these agents in the acute management of trauma, the adult trauma registry of The Johns Hopkins Hospital was reviewed to determine the frequency of use of these agents in acute airway management and to assess the effect of these agents on the incidence of complications. Ninety-seven patients were reviewed. Thirty-one patients were intubated because of cardiopulmonary arrest. Of the remaining 66 patients, oral intubation was initially attempted in 54. When drugs were used to facilitate intubation (n = 36), the success rate was 92 per cent on the first attempt, and 100 per cent on the second attempt. When drugs were not used (n = 18), 39 per cent could not be intubated (n = 7). Subsequent drug administration resulted in successful intubation of five of seven of these patients. Nasal intubation (no drugs) was only successful in 60 per cent of the patients (50 per cent on first attempt). Four patients required a cricothyrotomy. Two other patients vomited, and one patient aspirated. None of these patients received drugs prior to the first attempt at intubation. No hemodynamic or neurologic complications, related to relaxant or induction agent use, were observed. These findings suggest that oral intubation with drugs to facilitate airway management is most likely to result in successful intubation on the first attempt and that drug use in the trauma setting is safe.

Airway intubation in injured patients at the scene of an accident.

Trauma patients requiring intubation at the scene of the accident were entered into a study from June 1985 to June 1987 to determine: 1) the success rate of intubation by flight crews and 2) factors important in managing the difficult airway at the scene. One hundred thirty-six patients were reviewed. The success rate of trauma patients intubated in the field was 92.6%. The success rate of each procedure was, orotracheal 87%, and nasotracheal 77.6%. Six out of the 10 patients unsuccessfully intubated had vomiting or blood in the oropharynx which was cited as the reason for failure of intubation. All 24 patients requiring medications (paralytics and sedatives) for intubation were successfully intubated. Trismus and combativeness were the indications for medication usage. An aeromedical crew (MD, RN, RT) can successfully intubate trauma patients at the scene of the accident. Severe facial injuries with vomiting and blood in the oropharynx are factors in intubation failure. The use of muscle relaxants and sedatives facilitates difficult intubations.
