Research output: Contribution to journalArticlepeer-review


The objective of this research was to examine differences in outcome between primiparous women who do and who do not have suturing to first or second degree perineal lacerations sustained during spontaneous vaginal births after 37 weeks of gestation. One thousand and three hundred fourteen women were recruited to the trial antenatally from whom 74 were randomised either to be sutured or not sutured immediately after giving birth. Randomisation was stratified by degree of tear. Findings indicated that there were no significant differences between the groups with regard to pain or depression but there were differences with regard to healing. At six weeks, there remained a significant difference in wound closure between the groups, with women who had not been sutured having poorer wound approximation.
