A controlled trial on wound drainage in caesarean section.

A randomized controlled trial was carried out to investigate the influence of drainage on wound infection following Caesarean section. The incidence of clinical wound infection was significantly reduced if a Redivac suction drain was placed beneath the rectus sheath. Subcutaneous corrugated drains were found to offer no advantage. Three different degrees of postoperative pyrexia are examined for their predictive value for the development of wound sepsis. The influence of duration of amnion rupture and the number of vaginal examinations in labour on the postoperative incidence of wound infection and pyrexia are examined.
