Case Reports
Fiber-optic bronchoscopic guidance for intubating a neonate with Pierre-Robin syndrome.
The Pierre-Robin anomalad features micrognathia, glossoptosis, and frequently a cleft palate. Tracheal intubation may be challenging and sometimes impossible. ⋯ The bronchoscope was then removed, and an endotracheal tube was threaded over the wire. The technique is safe and allows rapid endotracheal intubation in pediatric patients with difficult upper airways.

Randomized Controlled Trial Comparative Study Clinical Trial
A new system for location of endotracheal tube in preterm and term neonates.
A randomized, controlled trial was conducted to evaluate a new noninvasive system for placement of the endotracheal tube, based on a magnetic field interference-sensing technique. Seventy-two neonates treated by the standard technique were compared with 70 treated by the new system (TRACH MATE), with radiographic localization as the standard. As judged by the author(s) on the morning after the intubation, correct initial placement was achieved in 69 (78%) of 88 intubations using the new system, compared with 71 (66%) of 107 using the standard technique (Fisher's Test, one-tailed, P = .044). ⋯ Endotracheal tube position (high, low, or appropriate) was correctly determined by TRACH MATE in 77 (90%) of 85 intubations; the position was not recorded on three occasions. No differences in the number of complications (eg, unplanned extubations, distal displacement, subglottic stenosis) were found between the two groups. It is concluded that the TRACH MATE technique is superior to the standard clinical method in initial placement of the endotracheal tube.

Randomized Controlled Trial Comparative Study Clinical Trial Controlled Clinical Trial
Effects of diazoxide on the cardiovascular response to tracheal intubation.
The efficacy of 2 or 3 mg/kg diazoxide given 2.5 min before laryngoscopy in attenuating the cardiovascular responses to laryngoscopy and intubation was studied in 30 patients undergoing elective surgery. Data were compared with those from 10 control patients receiving saline. ⋯ The increases following tracheal intubation were significantly reduced (P less than 0.05) in diazoxide-treated patients compared with those in the control group, but there were no significant differences in heart rate following tracheal intubation among the three groups. Data suggest that diazoxide can be used as a supplement during induction of anaesthesia to attenuate the hypertensive response associated with laryngoscopy and tracheal intubation.

A prospective study of unexpected, difficult laryngoscopy was carried out. During a 7-month period, all general surgery patients in whom the trachea was intubated were assessed; only those with obvious neck pathology were excluded. Ease or difficulty of laryngoscopy was graded by a standard method. ⋯ There were significant differences in the results recorded by different individuals; this did not correlate with seniority or with the type of surgery. Four factors have been identified which help to explain these discrepancies. These findings are analysed in relation to the training of junior staff, with particular reference to obstetric anaesthesia.
