The prevalence and significance of low preoperative hemoglobin in ASA 1 or 2 outpatient surgery candidates.

Asymptomatic anemia in healthy patients undergoing low risk surgery is rare. In this retrospective study, we examined the records of 9584 ASA class I-II patients scheduled for elective low risk surgery who had a preoperative hemoglobin (hgb) test for the presence of anemia. Hgb <9 g/dL was detected in 75 patients (0.8%). Perioperative management of anemia occurred in no cases of elective surgery in this group. Transfusion of red cells occurred in four other patients, all of whom had hgb >9 g/dL. In all cases, management decisions were based on clinical factors rather than the preoperative hemoglobin test. In healthy patients undergoing low risk elective surgery, routine preoperative hgb testing is not indicated.

Microbicides: a new approach to preventing HIV and other sexually transmitted infections.

Many chemical agents can block human immunodeficiency virus (HIV) infection in the laboratory. Scientists are investigating which of these, used intravaginally by women, will safely prevent the sexual transmission of HIV in humans. Several such products - microbicides - will soon be tested in populations at high risk for HIV, and others are waiting in the wings. Microbicides will provide a low-cost method, controlled by women, for protection against HIV, other sexually transmitted pathogens and unwanted pregnancy, and will therefore have global public-health benefits.
