Placement of Bupivacaine-soaked Spongostan in Episiotomy Bed Is Effective Treatment Modality for Episiotomy-associated Pain

Acute pain management after vaginal delivery with perineal tears or episiotomy

BACKGROUND

A vaginal delivery may be associated with acute postpartum pain, particularly after perineal trauma. However, pain management in this setting remains poorly explored.

OBJECTIVE

The aim of this systematic review was to evaluate the literature and to develop recommendations for pain management after a vaginal delivery with perineal trauma.

EVIDENCE REVIEW

MEDLINE, Embase, and Cochrane databases were searched for randomized controlled trials (RCTs) and systematic reviews assessing pain after a vaginal delivery with perineal tears or episiotomy until March 2023. Cochrane Covidence quality assessment generic tool and the RoB Vis 2 tool were used to grade the quality of evidence.

FINDINGS

Overall, 79 studies (69 RCTs and 10 systematic reviews and meta-analyses) of good quality of evidence were included. Acetaminophen and non-steroidal anti-inflammatory drugs (NSAIDs) are recommended as first-line treatment. Epidural morphine (≤2 mg) is recommended among women with labor epidural analgesia and severe perineal tears, with adequate respiratory monitoring. Local anesthetic infiltration, topical local anesthetic, ointment application, and pudendal nerve block are not recommended due to insufficient or lack of evidence. Ice or chemical cold packs are recommended for postpartum pain first-line treatment due to their simplicity of use. Transcutaneous nerve stimulation and acupuncture are recommended as adjuvants. When a perineal suture is indicated, a continuous suture compared with an interrupted suture for the repair of episiotomy or second-degree perineal tears is recommended for the outcome of pain. For women with first-degree or second-degree perineal tears, no suturing or glue compared with suturing is recommended for the outcome of pain.

CONCLUSIONS

Postpartum pain management after a vaginal delivery with perineal trauma should include acetaminophen, NSAIDs, and ice or chemical cold packs. Epidural morphine should be reserved for severe perineal tears. A surgical repair technique should depend on perineal tear severity.

The effect of Achillea millefolium and Hypericum perforatum ointments on episiotomy wound healing in primiparous women

BACKGROUND

The purpose of this study was to assess the efficacy of Achillea millefolium and Hypericum perforatum ointments on episiotomy wound healing in primiparous women.

MATERIALS AND METHODS

This is a double-blind clinical trial study performed on 140 primiparous women. They were randomly divided into four groups, each group containing 35 women: 2control groups including nonintervention and placebo ointment; and 2 case groups including Hypericum perforatum ointment and Achillea millefolium ointment. Healing process was assessed by five specifications: redness, ecchymosis, edema, discharge and wound dehiscence on 7th, 10th, and 14th days after delivery; pain level was assessed by means of visual analog scale.

RESULTS

There was significant difference between groups in perineal pain level at 7th, 10th and 14th days postpartum, redness and edema at 7th and 10th days postpartum and ecchymosis at 7th day postpartum; the pain level, redness, edema and ecchymosis in groups who consume Hypericum perforatum and Achillea millefolium ointments were less than the control groups (p < 0.05). But, discharge and dehiscence incidence showed no significant difference between groups (p > 0.05).

CONCLUSIONS

Achillea millefolium and Hypericum perforatum ointments reduce perineal pain level, redness, edema and ecchymosis of episiotomy wound, so it seems that consuming them was useful for episiotomy treatment.

A comparative study on relieving post-episiotomy pain with diclofenac and indomethacin suppositories or placebo

In this study, we compare the prophylactic efficacy of a diclofenac suppository and an indomethacin suppository on decreasing post-episiotomy pain. A total of 90 women with 2nd-degree episiotomy were assigned to receive a single dose of diclofenac suppository (30), indomethacin suppository (30) or placebo (30), according to randomised blocks. The pain was assessed at 1, 2, 4, 6 and 12 hours after receiving analgesia, using the two methods of pain score and visual analogue. This study showed that in the group given diclofenac or indomethacin, at all the assessed hours, the pain measured was considerably less than in the suppository-free group (p < 0.05). Comparing the diclofenac and indomethacin groups, there were only significant differences in the 4 and 12 hour measurements: the diclofenac was more effective than the indomethacin (4th hour), but due to a shorter half-life, the diclofenac group in the 12th hour had more pain (p < 0.05). Diclofenac suppository is recommended at 4-hour intervals for all patients, without internal disorders, to decrease episiotomy pain.
