RESUMEN

Before and after the operation, benzidine test of the swabs taken from 128 and 123 pairs of the protective eyeglasses wared by the assistants were used to determine the presence of blood contamination. The incidence of blood splash to the protective eyeglasses of the operators and the assistants were 56.3% and 25.2% while 52.8% and 70.9% of the contaminated protective eyeglasses were undetected by the operators and the assistants. The factors influencing the incidences were the indications and the urgency of the operations. Because of the high rats of blood splash during cesarean section, obstetricians should were protective eyeglasses during the operation to minimize the risk of exposure to potentially infectious blood.
