ObjectiveTo evaluate the effect of intraoperative use of soluble hemostasis gauze on postoperative pelvic infection in parturients undergoing cesarean section.MethodsData about cesarean section parturients in obstetric group（n=322）and gynaecology group (n=92) were surveyed by clinical followup and retrospective analysis method, obstetric group adopted bulk packing of gauze，gynaecology group adopted flat lay packing  , incidence of postoperative pelvic infection between  parturients who used soluble hemostasis gauze with different packing methods, as well as  with different pieces were compared and analyzed. ResultsPelvic infection rate in  obstetric group and gynaecology group was 4.04%（13/322） and 0.00%（0/92） respectively，there was no significant difference between  two groups（P=0.082 ).  In obstetric group, pelvic infection rate in parturients who used ≤3 pieces of soluble hemostasis gauze was 0, used >3 pieces was 11.82%,  there was significant difference between the two (P<0.001).ConclusionRational use of soluble hemostasis gauze in caesarean operation can effectively avoid postoperative pelvic infection.
