An evaluation of the Universal PAC and Oxford Miniature Vaporizers for paediatric field anaesthesia.
A laboratory study has demonstrated that the Universal PAC and Oxford Miniature Vaporizers can be used for paediatric anaesthesia in drawover mode at varying ambient temperatures. Changes in tidal volume have minimal effect on the delivered concentration of halothane from either vaporizer but varying ambient temperature significantly affects the output of the Oxford Miniature Vaporizer. The Oxford performs well in continuous flow mode, which is of particular use for T-piece anaesthesia, whereas the Universal PAC does not perform adequately in this way.

Randomized Controlled Trial Clinical Trial
Effect of intrathecal sufentanil on isoflurane requirements during lower abdominal surgery.
To determine the effect of intrathecal sufentanil on volatile anesthetic requirements during lower abdominal surgery. ⋯ Prior administration of intrathecal sufentanil significantly decreases the isoflurane requirement in surgical patients, in addition to its previously demonstrated rapid onset and receptor efficacy.

A wartime embargo on casualty figures and an imprecise contemporary editorial contributed to the persisting belief that a grossly excessive mortality rate from barbiturate anaesthesia for surgery of the injured occurred after the Japanese attack on the American bases in Hawaii in December 1941. From accounts by surgical staff and official hospital records which have become available through US Freedom of Information legislation, it is clear that the rumoured death rate from this cause has been greatly exaggerated.

Pulmonary Edema associated with negative airway pressure caused by upper airway obstruction is a most serious complications in anaesthetic practice (Tami et al, 1986). Laryngospasm associated with intubation and general anaesthesia is the most common cause of upper airway obstruction leading to negative pressure pulmonary edema (NPPE) in the anaesthetic adult (Tami et al, 1986). ⋯ NPPE appears to be related to markedly negative intrathoracic pressure due to forced inspiration against a closed upper airway resulting in transudation of fluid from pulmonary capillaries to the interstitium. The following is a presentation of a case of a healthy young male who developed NPPE secondary to airway obstruction caused by biting down on the endotracheal tube while awakening from general anaesthesia.
