Comparison of Transcutaneous Electrical Nerve Stimulation and Lidocaine on Episiotomy Complication in Primiparous Women: A Randomized Clinical Trial

The Effects Of Transcutaneous Electrical Nerve Stimulation Applied in the Early Postpartum Period After Cesarean Birth on Healing, Pain, and Comfort

INTRODUCTION

This study was conducted to determine the effects of transcutaneous electrical nerve stimulation (TENS) applied in the early postpartum period after cesarean birth on incision site healing, postoperative recovery, pain, and comfort.

METHODS

This randomized, single-blind, placebo-controlled study was conducted with 138 women (TENS group n = 46, placebo group n = 46, control group n = 46) who gave birth by cesarean between January and September 2023. TENS was applied twice at a frequency of 100 Hz with a pulse width of 100 microseconds, at 10 to 12 and 14 to 16 hours after birth, for 30 minutes each. Outcomes were measured with the Postoperative Recovery Index; Redness, Edema, Ecchymosis, Discharge, and Approximation Scale; Visual Analogue Scale; and Postpartum Comfort Questionnaire. Outcomes between groups were compared postintervention, correcting for baseline using analysis of covariance. The study was registered at www.

CLINICALTRIALS

gov (NCT05991921).

RESULTS

Mean scores for postoperative recovery were significantly lower (improved) in the TENS group (113.58) compared with the placebo and control groups (134.67, 136.61; P < .001). The postoperative recovery subscales (psychological symptoms, physical activities, appetite symptoms, bowel symptoms, general symptoms) were also significantly decreased in the TENS group compared with the placebo and control groups. Similarly, mean scores for postpartum comfort, and the corresponding physical comfort, psychospiritual comfort, and sociocultural comfort subscales, were significantly improved in the TENS group (110.26) compared with the placebo and control group (83.80, 81.19; P < .05).

DISCUSSION

TENS application can be preferred as an alternative method to increase pain control, recovery, and patient comfort after cesarean birth.

Effectiveness of Olea Herbal Ointment on Episiotomy Wound Healing Among Primiparous Women: A Randomized Clinical Trial

Background: Episiotomy is a surgical incision in the perineal region to increase the vaginal diameter during delivery. Since the perineal region is not well visible to the mothers and there is a possibility of infection for the episiotomy wound by vaginal and rectal bacteria, such a cut is associated with infection and delay in wound healing. Objectives: This study aimed to detect the effect of Olea ointment on episiotomy wound healing among primiparous women. Methods: This randomized controlled clinical trial included 73 women referring to the Al-Zahra Education, Research, and Remedial Center in Rasht, Iran, during 2017 - 18. Women were randomly assigned into two groups: Intervention group (n = 39) and control group (n = 34). Episiotomy wound healing was assessed using the REEDA scale prior to the intervention, 2 and 24 hours following the first intervention, and 5 and 10 days after delivery. Statistical analysis was performed using Fisher’s exact test, Mann-Whitney U test, independent t-test, repeated-measure test, Friedman test, and chi-square. Results: The mean baseline scores of REEDA was 2.72 ± 0.46 in the Olea ointment group and 2.71 ± 0.46 in the control group; however, there was no statistically significant difference between the two groups. On the other hand, the episiotomy healing scores in the Olea ointment group were significantly lower than those of the control group at four intervals in the follow-up assessments: -0.34 (95% CI: -0.56 to -0.12) two hours after intervention, -0.63(95% CI: -0.89 to -0.37) 24 hours after intervention, -0.30 (95% CI: -0.48 to -0.12) on Day 5 postpartum, and -0.29 (95% CI: -0.46 to -0.13) on Day 10 postpartum. Conclusions: The present findings suggested that the Olea ointment facilitated wound healing of episiotomy; however, further studies are suggested to support these data.

The Effect of Olea Ointment on Post-Episiotomy Pain Severity in Primiparous Women: A Paralleled Randomized Controlled Clinical Trial

Background:

Episiotomy is the most commonly performed surgical procedure during delivery, and its associated pain is a major problem in obstetrics. This study aimed to determine the effect of Olea ointment on the severity of post-episiotomy pain in primiparous women.

Materials and Methods:

This paralleled randomized controlled clinical trial was performed on 73 primiparous women in Al-Zahra hospital in Rasht, Iran in 2017-2018. Women were randomly allocated into intervention (n = 39) and control (n = 34) groups. The first intervention was performed 4 h after the episiotomy. This continued every 8 h for 10 days. The pain intensity of episiotomy was assessed by the Visual Analogue Scale (VAS) before intervention, 2 and 24 h after the beginning of intervention, and 5 and 10 days after childbirth. Descriptive and inferential statistics (Mann-Whitney, Fisher exact test, Independent t-test, Friedman test, and Chi-square) were performed for statistical analysis.

Results:

There were no significant differences among two groups in terms of demographic and obstetrics characteristics. The severity of pain in intervention and control group before the intervention was not statistically significant, but the variable depicted a meaningful difference between the groups 2 h after the intervention (U = 483.50, p = 0.021), 24 h after the intervention (U = 489.50, p = 0.019), as well as the 5^th day (U = 112.50, p < 0.001) and 10^th day postpartum (U = 136.50, p < 0.001).

Conclusions:

Based on the findings, Olea ointment could be used effectively for reducing of episiotomy pain. Similar studies are recommended.

The Effects of Transcutaneous Electrical Nerve Stimulation on Post-Episiotomy Pain Severity in Primiparous Women: A Randomized, Controlled, Placebo Clinical Trial

Background:

Episiotomy or cutting the perineum is the most common operation in obstetrics. Perineal pain is the main complication of episiotomy that affects the quality of life and mental health of the mother. Reducing the pain and side effects of the chemical drugs prescribed for pain relief has attracted the attention of both physicians and scientists. This study was conducted to determine the effects of transcutaneous electrical nerve stimulation (TENS), as an alternative method, on post-episiotomy pain severity.

Materials and Methods:

This randomized clinical trial was performed on 120 primiparous women who had referred to Sanandaj Besat Hospital in 2018. The patients were divided randomly into three groups, including the intervention group (TENS-On), the placebo group (TENS-Off), and the control group. TENS electrodes were placed near the episiotomy site in genitofemoral and pudendal nerves. The pain was measured after episiotomy in lying, sitting, and activity positions. The pain severity was measured using a pain measurement instrument (numeral rating score) at four-time points, i.e., before the intervention as well as 30, 60, and 120 minutes after the TENS intervention. For data analysis, Pearson correlation, student’s t-test, Kruskal-Wallis test, ANOVA test, and Mann-Whitney U tests were used.

Results:

Intragroup evaluation results for placebo and control groups demonstrated no significant difference in the pain score (P>0.05). A significant difference was observed between the mean pain severity of the intervention group and that of the group with walking activities (P=0.04). In terms of the intergroup evaluation, there was a significant difference observed between the mean pain severity of the lying position and that of the control group (P=0.008). Regarding the sitting position, no significant difference was observed between its mean pain severity and that of the other two groups (P=0.04).

Conclusion:

TENS is an effective and safe method for post-episiotomy pain relief and a routine method used in the obstetrics and gynecology ward.
