RESUMO
An i.v. solution of 5% dextrose with doxapram 2 mg ml-1 or 5% dextrose alone was administered to 53 patients following lateral thoracotomy. Estimations of arterial PO2, PCO2 and pH were made before operation, during infusion and 7 days after after operation. Respiratory function tests were carried out before and 7 days after operation. There were no significant differences in arterial PO2, PCO2 and pH or in respiratory function tests between those who received doxapram and those who did not. In this study doxapram did not affect the frequency of postoperative pulmonary complications.

The Department of Health and Social Security has recently recommended that waste anaesthetic scavenging systems should be installed to reduce pollution in operating theatres. Three passive and two active systems were compared to see how effectively they reduced concentrations of halothane in the atmosphere. All five systems reduced halothane levels significantly, the combination of an active system and semiclosed circuitry being the most effective. All obvious leaks from equipment were controlled in this study, but normally such leaks contribute significantly to atmospheric pollution. Some of the benefits of a scavenging system may be lost if gases can still escape through leaks.
