A comparison of midazolam co-induction with propofol predosing for induction of anaesthesia.

In a double-blind, placebo-controlled study of 90 ASA 1 and 2 patients scheduled for elective surgery we compared the effect of pre-administering midazolam 2 mg or propofol 30 mg on the dose of propofol subsequently required to induce anaesthesia. Using loss of response to verbal command and tolerance to placement of a facemask as end-points, the dose of propofol required to induce anaesthesia was significantly smaller in the patients given propofol (1.87 mg.kg-1) or midazolam (1.71 mg.kg-1) when compared to the control group (2.38 mg.kg-1). Although the decrease in blood pressure following induction was no difference between the two study groups and the decrease was felt not to be of clinical significance in this group of patients. As propofol is presented ' ... for use in a single patient only' and the technique of predosing with propofol allowed induction of all patients with less than 200 mg (a single ampoule), we question on a cost basis whether midazolam co-induction is necessary to reduce propofol induction doses.

Side effects from influenza vaccination: differences between returned and random surveys.

Annually vaccinated Air National Guard members were surveyed by return of questionnaire in 1991 (20.5%) and in 1992 by random phone survey (23.5%). By returned questionnaire the sample reported any side effects at the rate of 48.1%; by randomly telephoned sample a significantly lower rate, 37.7% (p < 0.02), was reported. An inverse relationship existed between age and return of the questionnaire, present only in males, despite an increased rate of reporting of side effects in the younger ages. Females reported a significantly higher rate of side effects than males by return of questionnaire in all age groups and for the sample as a whole (p < 0.03). In the randomized survey the age effect disappeared, except for the tendency for the oldest group to report fewer side effects than the other age groups in their aggregate (p < 0.07). The higher reporting rate for females was less apparent by random survey but remained as a trend (p = 0.08; odds ratio 1.398; 95% confidence interval = 0.776-4.049).

Sociodemographic factors associated with AIDS knowledge in a random sample of university students.

A telephone survey was used to assess knowledge of the transmission, prevalence, and infectivity of acquired immunodeficiency syndrome (AIDS), and the safety of casual contact among 214 randomly selected university students. Males were more knowledgeable than females overall (odds ratio [OR], men/women = 4.8). Although most students understood the dangers of unprotected sex and intravenous needle sharing, up to 30% believed some kinds of casual contact (e.g., shared eating utensils) can transmit AIDS. Older students (greater than or equal to 23 yrs) were more knowledgeable than those 17 to 19 years old about the safety of casual contact (OR = 3.8). Students are in need of education programs that stress the ways AIDS is not transmitted. Since most students identified newspapers and television as their main sources of information, these may be effective vehicles for education efforts.
