High-frequency jet ventilation is a useful new modality of ventilatory support that offers specific advantage in endoscopy, laryngeal surgery, or mechanically ventilating patients with airway leaks. The method produces lower airway pressures and less movement in the operative field and is well tolerated by the patients. It can be applied by transtracheal(More)
Aspiration is a potentially fatal complication of artificial ventilation. A cuffed tube is generally used now to prevent aspiration; however, it may lead to serious complications and has several disadvantages. High frequency jet ventilation (HFJV) is an innovative technique to prevent aspiration. The trachea of 6 anesthetized, paralyzed dogs was exposed and(More)
The efficacy of intravenously administered lidocaine 0.75 mg/kg and 1.5 mg/kg to protect against cardiovascular reactions associated with laryngoscopy and tracheal intubation was studied in two comparable groups of ten patients and compared with a similar control group of ten patients given only saline. Following laryngoscopy and tracheal intubation, the(More)
A technique of nebulizing lidocaine in the upper airways was developed and its effectiveness in preventing cardiovascular responses to laryngoscopy and intubation was documented. In ten pre-treated patients the average percentage-rise in systolic blood pressure was 10.3 per cent and there were no arrhythmias. The pulse rate increased by 16.8 per cent. In(More)
Two comparable groups of ten patients were studied. After nitrous oxide-oxygen fentanyl-pancuronium anesthesia, half the patients were reversed with a titrated dose of naloxone. Even in titrated doses naloxone rapidly abolished residual post-operative fentanyl analgesia in 80 p. 100 of the patients. In the control group none of the patients complained of(More)
