RISK OF EYE SPLASH IN OBSTETRIC PROCEDURES

A prospective cross-sectional study was designed to determine the rates of upper facial splash during obstetric deliveries. Macroscopic splashes on the attached eye shields of surgical masks, worn for obstetric deliveries were enumerated for a sample of parturients during a 3-month period. Masks were collected for 68 vaginal and 44 cesarean deliveries, 31% of all deliveries during the study period. For cesarean deliveries, 68% (30) of all masks worn by primary surgeons had at least one splash; 57% (17) of which were heavily contaminated (more than five splashes). For the first assistant, 68% (30) of all masks had at least one splash; 23% (7) of which were heavily contaminated. During vaginal deliveries 44% (30) of masks worn by the delivering physician had at least one splash; 20% (6) of which were heavily contaminated. The primary surgeon in a cesarean section was 1.6 times as likely to be splashed (P <0.04) when compared with vaginal deliveries and 4.6 time as likely to be heavily contaminated (P <0.003). Estimated blood loss and the rate of eye splash were linearly related. Method of delivery was not independently associated with eye splash. These findings suggest that the risk of contamination by splash during obstetric procedures is high, particularly for cesarean deliveries because these deliveries tend to have greater blood losses.
