The effect of scavenging on nitrous oxide pollution in the delivery suite.

United States standards recommend limits to occupational exposure to nitrous oxide. This can be achieved by the scavenging of waste anaesthetic gases, a routine practice in the operating suite, but less common in the delivery suite. In this study, nitrous oxide levels in the delivery room were measured, and scavenged and unscavenged levels were compared. Unacceptable levels of nitrous oxide were found in unscavenged delivery rooms, and in the majority of cases, scavenging reduced nitrous oxide pollution to within recommended limits.

Attenuation of electroconvulsive therapy induced hypertension with sublingual nifedipine.

Five patients known to be previously hypertensive but not currently receiving anti-hypertensive medications were studied for a total of twenty-six administrations of electroconvulsive therapy. Patients randomly received sublingual nifedipine 10 mg, 20 minutes prior to half of their treatments, and for the remaining treatments acted as their own controls. The use of nifedipine resulted in significant attenuation of the blood pressure response to therapy. Systolic pressure increase was 24 mmHg (SD 14) versus 62 mmHg (SD 24) (P less than 0.01). There was no difference in heart rate between the two groups. It is concluded that nifedipine reduces the pressor response to electroconvulsive therapy in individuals with a history of hypertension.
