Surgical glove powder and intraperitoneal adhesion formation. An appeal for the use of powder-free surgical gloves.

Intraperitoneal adhesion formation is a major cause of infertility and/or intestinal obstruction. Among the many well-known aetiological factors responsible for peritoneal inflammatory reaction is surgical glove powder; for example, cornstarch powder. A study was undertaken on 30 rats to determine whether cornstarch powder caused intraperitoneal adhesions. The rats were randomised into two groups under laboratory conditions. Laparotomies were performed on all the rats and trauma inflicted to the right uterine horn. The study group received cornstarch powder suspended in normal physiological salt solution intraperitoneally, and the control group received only normal physiological salt solution. Peritoneal adhesions were evaluated after 2 weeks and statistically analysed with a t-test and 95% confidence intervals. The study group showed a statistically significantly higher incidence of intraperitoneal adhesions (P = 0.0003). It is concluded that cornstarch, as used on surgical gloves, caused peritoneal adhesions and should therefore be removed before surgery. Powder-free gloves are more suitable for preventing adhesion formation.
