A simple method for preventing obstruction of the endotracheal tube during palatal surgery.
In this paper we describe a simple method for avoiding the obstruction of the Mallinckrodt R. A. E. (Ring, Adair and Elwin) preformed endotracheal tube which we use during cleft palate surgery, palatal lengthening and pharyngoplasty in patients who have well developed lower incisor teeth.

Randomized Controlled TrialInfluence of beta-blockers on vecuronium/sufentanil or pancuronium/sufentanil combinations for rapid induction and intubation of cardiac surgical patients.
Use of pancuronium or vecuronium with the priming principle was evaluated in regards to hemodynamic changes and adequacy of relaxation for a rapid induction-endotracheal intubation sequence with sufentanil in 24 ASA Class III-IV patients undergoing cardiac surgery. Twelve patients taking beta-blockers (groups B-P and B-V) were compared with 12 patients not receiving beta-blockers (groups NB-P and NB-V). Patients randomly received vecuronium or pancuronium (15 microg/kg), followed in 4 minutes by sufentanil 5 microg/kg and another 85 microg/kg of the appropriate relaxant through a central vein. ⋯ Chronic beta-blocker therapy was able to attenuate the tachycardia from pancuronium and was not associated with bradycardia when used with vecuronium. In patients with cardiac disease not on beta-blockers, pancuronium was associated with tachycardia. Therefore, vecuronium appears to be more suitable for these patients.

Randomized Controlled Trial Clinical TrialThe use of labetalol for attenuation of the hypertensive response to endotracheal intubation in preeclampsia.
Twenty-five women with preeclampsia who were scheduled to undergo cesarean section under general anesthesia were randomly assigned to either a labetalol pretreatment group (n = 15) or a control group (n = 10) who did not receive any antihypertensive therapy before the induction of anesthesia. Patients in the labetalol group received 20 mg of labetalol intravenously followed by 10 mg increments up to a total dose of 1 mg/kg, which resulted in moderate reductions in the maternal mean arterial pressure and heart rate with attenuation of the hypertensive and tachycardiac responses to laryngoscopy and endotracheal intubation. ⋯ The neonatal Apgar scores and umbilical arterial and venous pH and blood gas values were similar in the two groups. Side effects such as hypotension, bradycardia, and hypoglycemia were not seen in the neonates in the labetalol treatment group.

Comparative StudyUse of flexible fiberoptic endoscopy for determination of endotracheal tube position in the pediatric patient.
Flexible fiberoptic endoscopy (FFE) was utilized in a series of 24 critically ill pediatric patients to determine the position of the endotracheal tube (ETT) tip relative to the carina. Training on a model system revealed no significant differences in predicting ETT-to-carina distance (ETT-C) with respect to operator, ETT size, or absolute ETT-C as measured directly. No significant differences in ETT-C could be determined between traditional bedside chest x-ray (CXR) or FFE when FFE was performed on intubated pediatric ICU patients. ⋯ No clinically significant changes in patient pulse oximetry, heart rate, or physical exam were observed during FFE. Only copious secretions impaired the utility of FFE. We concluded that FFE is a safe, fast, easily learned method to determine relative ETT position or precise ETT-C in the mechanically ventilated pediatric patient.

Stenosis of the larynx and trachea is an unfortunate sequel to many thermal injuries. Numerous surgical techniques have been developed for correction of such problems, many involving use of a tracheal T-tube. We report a serious complication attributed to the use of such a tube. Factors contributing to this complication are analyzed and methods for avoiding similar near-catastrophes discussed.
