In this analysis 536 caesarean sections with a single layer uterine suture were compared to 256 sections with two layer closure. Their relations with regard to indications of operative delivery, complications during the puerperium and their courses in subsequent vaginal deliveries were taken into consideration. - The significant lower rate of pyrexia and shorter hospital stay of the patients may be a result of quicker and better healing of the single layer suture. The increased rate of complications in the puerperium is partially due to changes in the registry of dates. Absent disturbances during the placental period and the occurrence of only one uterine rupture, in the course of vaginal delivery in a patient with a previous single layer caesarean section suture, demonstrates the functional sufficiency of this technic.
