Clinical application of fiberoptic bronchoscope combined with visual laryngeal mask awake tracheal intubation technique: a case report.

ABSTRACT: We presented a case of successful awake endotracheal intubation in a patient with a giant goiter and severe tracheal stenosis. The patient had difficulty in airway management during the perioperative anesthesia due to tracheal deviation and stenosis caused by tumor compression. We applied a visual laryngeal mask combined with fiberoptic bronchoscope to visualize the whole procedure of endotracheal intubation, from visually assessing the glottic, subglottic, and the tracheal conditions, to evaluating the pressure of the tumor on the trachea and the maximum tracheal tube diameter that could be passed. During the entire process, the patient remained awake, maintained spontaneous breathing, and actively cooperated with the clinical staff. Hence, we demonstrated that this method is safe, effective, operable, and could be generalized as a form of endotracheal intubation for patients with known difficult airways.

Project description:BackgroundThere are many factors affecting the success rate of awake orotracheal intubation via fiberoptic bronchoscope. We performed this study was to investigate the effects of head positions on awake Fiberoptic bronchoscope oral intubation.MethodsSeventy-five adult patients, received general anaesthesia were included in this study. After written informed consent, these patients were undergoing awake orotracheal intubation via fiberoptic-bronchoscope and according to the head position, the patients were randomized allocated to neutral position group (NP group), sniffing position group (SP group) or extension position group (EP group). After sedation the patients were intubated by an experienced anesthesiologist. The time to view the vocal cords, the percentage of glottic opening scores (POGO), the time to insert the tracheal tube into trachea and the visual analog scale (VAS) scores for ease experienced of passing the tracheal tube through glottis, the hemodynamic changes and the adverse events after surgery were recorded.ResultsThe time to view the vocal cords was significantly shorter and the POGO scores was significantly higher in the EP group compared with the other two groups (P < 0.05); The SpO2 in the EP group was higher than NP group at before intubation and higher than SP group and NP group at immediate after intubation (P < 0.05); The time to insert the tracheal tube into trachea, the VAS scores for passing the tracheal tube through glottis, the coughing scores had no significant differences among groups (P > 0.05). There were also no significant differences regard to the incidence of postoperative complications, mean arterial pressure and heart rate among the groups (P > 0.05).ConclusionsThe head at extension position had a best view of glottic opening than neutral position or sniffing position during awake Fiberoptic bronchoscope oral intubation, so extension position was recommended as the starting head position for awake Fiberoptic bronchoscope oral intubation.Trial registrationClinical Trials.gov. no.

Project description:BackgroundHypoxemia is the most common complication during tracheal intubation of critically ill adults and may increase the risk of cardiac arrest and death. Whether positive-pressure ventilation with a bag-mask device (bag-mask ventilation) during tracheal intubation of critically ill adults prevents hypoxemia without increasing the risk of aspiration remains controversial.MethodsIn a multicenter, randomized trial conducted in seven intensive care units in the United States, we randomly assigned adults undergoing tracheal intubation to receive either ventilation with a bag-mask device or no ventilation between induction and laryngoscopy. The primary outcome was the lowest oxygen saturation observed during the interval between induction and 2 minutes after tracheal intubation. The secondary outcome was the incidence of severe hypoxemia, defined as an oxygen saturation of less than 80%.ResultsAmong the 401 patients enrolled, the median lowest oxygen saturation was 96% (interquartile range, 87 to 99) in the bag-mask ventilation group and 93% (interquartile range, 81 to 99) in the no-ventilation group (P = 0.01). A total of 21 patients (10.9%) in the bag-mask ventilation group had severe hypoxemia, as compared with 45 patients (22.8%) in the no-ventilation group (relative risk, 0.48; 95% confidence interval [CI], 0.30 to 0.77). Operator-reported aspiration occurred during 2.5% of intubations in the bag-mask ventilation group and during 4.0% in the no-ventilation group (P = 0.41). The incidence of new opacity on chest radiography in the 48 hours after tracheal intubation was 16.4% and 14.8%, respectively (P = 0.73).ConclusionsAmong critically ill adults undergoing tracheal intubation, patients receiving bag-mask ventilation had higher oxygen saturations and a lower incidence of severe hypoxemia than those receiving no ventilation.

Project description:ObjectivesThis study sought to evaluate the impact of peer coaching as a continuing medical education (CME) modality to improve faculty performance and teaching of a low-frequency, high-complexity procedure, awake fiberoptic intubation (AFOI).MethodsAcademic emergency medicine faculty at a single tertiary care, Level I trauma center participated in a prospective pre-/postinterventional assessment of a peer coaching educational intervention. Participants completed a preintervention online survey to identify comfort and previous experience with performing and teaching AFOI. The participants reviewed presession materials and then completed a 25-min didactic session with a peer coach. Participants were then broken into dyads where they initially each practiced the procedure and then attempted to teach the procedure to their colleague. An institutional standardized checklist for AFOI was utilized to assess participants procedural competency. Postintervention online surveys were compared to the preintervention surveys.ResultsA total of 15 faculty members were recruited for the study and completed pre- and postintervention surveys. All participants showed ability to perform AFOI as proven by successful completion of the procedural checklist. There was a statistically significant increase for self-perceived efficacy in performing (p < 0.001, 95% confidence interval [CI] = 1.34 to 3.06) and teaching AFOI (p < 0.001, 95% CI = 1.56 to 3.05). All participants felt more likely to attempt AFOI after a single peer coaching session and most (14/15, 93.3%) were more likely to teach AFOI. Participants identified peer coaching as more effective at instilling confidence to perform and teach the skill than other CME activities that they have experienced.ConclusionThis study demonstrates that peer coaching increases practicing faculty's ability to perform and teach a low-frequency, high-complexity procedure, AFOI. Peer coaching may offer an opportunity to improve the utility of learning compared to more traditional didactic-based CME initiatives.
