Upper airway bronchoscopic interpretation

When evaluating the posterior oral cavity and oropharynx, the endoscopist should take care to identify the palatine tonsils and their size and contribution to oropharyngeal collapse (Figure 4.3). Glossoptosis and lingual tonsillar hypertrophy (Figure 4.4) are also important in the evaluation of obstructive sleep apnea. With the flexible endoscope in place just inferior to the soft palate, a jaw thrust maneuver should be performed to assist in differentiation between these two conditions, as jaw thrust should improve an obstruction caused by glossoptosis (Figure 4.5). Symmetry of the vallecula should also be assessed. Masses located at the base of the tongue can include a lingual thyroglossal duct cyst (Figure 4.6) or a lingual thyroid, either of which can cause potential airway displacement and subsequent respiratory distress.9
Anesthesia for pediatric trauma
Published in David E. Wesson, Bindi Naik-Mathuria, Pediatric Trauma, 2017
The goals of airway management in the pediatric trauma patient include achieving adequate oxygenation and ventilation along with protection of the patient’s airway reflexes. The first priority within the Primary Survey is to evaluate and maintain the integrity of the airway. If the patient’s condition permits, a comprehensive airway evaluation should be performed. In the conscious child, the ability to vocalize is reassuring and may suggest a patent airway. In the unconscious child, the airway must be assessed quickly to confirm if breathing is present. If the patient has an obstructed airway, performing a jaw-thrust maneuver may reduce or eliminate the airway obstruction [14]. An oropharyngeal airway may also be considered to temporarily maintain upper airway patency until a definitive airway has been established. A nasopharyngeal airway should be used with caution particularly if midfacial injuries are suspected. Suctioning should also be considered if secretions are present. Verifying that airway obstruction is not related to inappropriate placement of the cervical collar is also indicated.
Comparison of the supraglottic airway device BlockBusterTM and laryngeal mask airway Supreme in anaesthetised, paralyzed adult patients: a multicenter randomized controlled trial

The positioning of the device in the upper airway was considered satisfactory when ventilation test was positive (peak inspiratory pressure <20 cmH2O, normal chest movements, and PETCO2 waveforms), OLP was greater than 20 cmH2O, and fiberscopic view was optimal (grades 1 and 2). If the positioning of the device was considered unsatisfactory, airway manipulations including neck flexion or extension, jaw thrust plus up-down maneuver, increase or decrease cuff volume and reinsertion would be performed to adjust device positioning. The ‘up-down maneuver’ was carried out by rotating the inflated device out of the oropharynx approximately 6 cm and then reinserting the device to free the epiglottis [16]. Jaw thrust plus ‘up-down maneuver’ in this study was a modified ‘up-down maneuver’ proposed by us based on the structural features of the SAD BlockBusterTM, in which the two thumbs performed the ‘up-down maneuver,’ while the other fingers made the jaw thrust maneuver. After airway manipulations were completed, the above tests were repeatedly performed to determine if the positioning of the device was satisfactory.

None of the patients had anesthesia related severe adverse events in both groups. However, we were not able to retrieve mild desaturation episodes that were managed with jaw-thrust maneuver, without the need for mechanical respiratory support. Similarly, the mortality rate was zero in our cohort. Notably, the length of hospitalization was significantly lower in group A as compared to group B (7.4 ± 2.9 vs. 9.7 ± 3.9 days, p = .0003) (Figure 1). The mean time interval between performing EUS and ERCP in group B was 3.7 ± 1.6 days. Of note, 2 out of the 45 patients (4.4%) in group B developed complication while awaiting ERCP performance, the first patient had exacerbation of heart failure manifested as pulmonary edema and atrial fibrillation and the second patient developed new onset heart failure. The mean cost of same day EUS and ERCP as been calculated by the length of hospitalization was significantly lower in group A as compared to group B (7680.9$ ± 3071.4$vs. 10089.4$ ± 4053.4$, p = .0003) (Figure 2).

in terms of the occurrence of side effects, both groups had comparable rates of bradycardia, tachycardia, hypotension, laryngeal spasm, nausea, vomiting, and postoperative cognitive dysfunction. The incidence of bradycardia in both groups was comparable (six patients in group (KD) versus four patients in group (KP), which was managed by stopping the procedure and administering 0.01 mg/kg atropine once). Only two patients in group KP experienced tachycardia, which was treated with an extra bolus dose of ketamine to increase the depth of sedation and analgesia. The incidence of hypotension was higher in group KP than in group KD, but the difference was not statistically significant (three patients in group (KD) versus five patients in group (KP), which was managed with a 250 mL ringer solution and a 6 mg ephedrine increment once). The prevalence of oxygen desaturation was statistically higher in group KP than in group KD (9 patients, and 3 patients respectively). All patients were managed by chin-lift or jaw-thrust maneuver and increasing oxygen flow to 6–10 L/min without the need for a nasal airway or manual ventilation. Unwanted movements were statistically more common in group KD than in group KP (6 patients, and two patients respectively). Three patients in group KD and two patients in group KP experienced nausea/vomiting in the recovery room and were given 4 mg ondansetron once. There were no patients who experienced laryngeal spasms or post-procedural psychotic symptoms (Table 10).
