Sir,—Intermittent jets of oxygen may be used to ventilate patients undergoing microlaryngoscopy with a Venturi injector or by flushing oxygen directly through a small-bore endotracheal tube as we have used in 10 adult patients (table I). The patients were premedicated with pethidine 75 mg and atropine 0.6 mg and anaesthesia was induced with propanidid 250-500 mg followed by suxamethonium 100 mg...

Hypoxemia is a frequent event during difficult airway management. We propose to use transtracheal jet ventilation (TTJV) early during the management of complex difficult airway scenarios. The objective of this porcine study is to highlight the benefit of oxygenation via prophylactic TTJV. Eighteen pigs (Sus scrofa) were divided into two equal groups. In Group A, pigs were anesthetized and no lu...

ASPIRIN poisoning is responsible for over 200 deaths per annum in England and Wales. Forced alkaline diuresis is advocated to hasten renal elimination of the drug when plasma salicylate levels exceed 500 mg/l, whilst charcoal haemoperfusion is the treatment of choice when plasma salicylate levels exceed 900 mg/kg.' This severity of poisoning causes gross respiratory, metabolic and coagulation d...

Needle cricothyrotomy is a safe, relatively easy procedure and has been described to enable pulmonary ventilation for patients in both elective and emergency situations. Conventional IV cannulae are short, thin-walled, and easily kinked and, therefore, do not provide a secure system to jet oxygen into the trachea. The vessel dilators of most 7-9 French introducer kits are firm, pliable, resist ...

Anesthesia for microlaryngeal surgery creates many obstacles for the anesthesiologist and otolaryngologist. Anesthetic techniques developed to improve surgical exposure have been met with significant limitations and are difficult for the anesthesiologist to monitor. A new subglottic jet ventilation anesthesia system is introduced that meets the needs of the otolaryngologist and the anesthesiolo...

This study aims to acquire an understanding of the fundamental feature IJV and DV under heating operation. Full-scale experiments were conducted these two different systems supply air conditions along with temperature distribution ventilation effectiveness. A wall surface test room was cooled as a load, elements simulating occupants located internal heat load contaminant emission source. Three ...
