Abstract
BACKGROUND
Perineal trauma pain is associated with perineal repair and its subsequent healing. New evidence is required concerning perineal repair techniques that cause less pain and favour healing.
OBJECTIVE
To compare three perineal repair suturing techniques after episiotomy or second degree tearing during a normal birth with respect to reducing pain and improving the perineal healing process.
DESIGN
A randomised controlled trial.
SETTING
A large public university hospital in Madrid, Spain.
PARTICIPANTS
Full term pregnant women older than 18 years-of-age, who required perineal repair after episiotomy or second degree tearing and were attended for normal birth by midwives.
METHODS
One hundred and eighty-three women were randomly assigned to three groups: the Continuous Suture Group (n = 58), Interrupted Cutaneous Suture Group (n = 53), or the Interrupted Subcutaneous Suture Group (n = 57). The study participants and data collectors were blinded to group allocations. Principal outcome: perineal pain 10 days after birth. Other outcomes: short (2 and 48 h) and long term (3 and 6 months) perineal pain after birth; short term healing; suture time.
RESULTS
At 10 days postpartum, the presence of spontaneous pain, pain when walking or moving in bed, was almost nonexistent in the 3 suture groups. The median (P25-P75) perineal pain on palpation was similar in the 3 groups, with values of 2 (1-4) in the Continuous Suture Group, 3 (2-5) in the Interrupted Cutaneous Suture Group and 2 (1-4) in the Interrupted Subcutaneous Suture Group; also were similar the perineal pain on sitting: 1 (0-3) in the Continuous Suture Group, 1 (0-2) in the Interrupted Cutaneous Suture Group and 1 (0-3) in the Interrupted Subcutaneous Suture Group. There were no statistically significant differences between the groups. Pain measurements throughout the follow-up period only showed statistically significant differences in 2 out of 22 evaluations: pain when sitting 48 h after birth and spontaneous pain at 3 months. The mean times (standard deviation) to carry out suturing were 12.86 (4.9) minutes in the Continuous Suture Group, 13.54 (5.6) in the Interrupted Cutaneous Suture Group, and 15.59 (6.9) minutes in the Interrupted Subcutaneous Suture Group (p < 0.05).
CONCLUSIONS
The three suturing methods described for perineal repair after episiotomy or second degree tearing after normal birth are comparable with respect to short, medium and long term perineal pain and the healing process. Use of the continuous suturing technique involved less time than interrupted suture methods. Tweetable abstract: proper the suturing methods for perineal repair after episiotomy or second degree tearing prevent postpartum perineal pain.
