Clinical Trial Summary

The present study aims to compare the effects of lidocaine-prilocaine cream and lidocaine injection on the reduction of pain while doing and repairing episiotomy, controlling the pain in the post-partum period, and reduction the risk of infection and dyspareunia in 6 weeks post-partum.


Description:

Population of study & disease condition: The study will be conducted on 60 patients that will be admitted to the labor ward in the Department of Obstetrics & Gynecology of a tertiary care center of Cairo University from Jan/2023 to Jan/2024 on. Primigravida women with singleton live pregnancy with cephalic presentation in the first stage of labor will be included in the study after approval by the Institutional Ethical Committee and obtaining an informed consent. Those with known allergy to lignocaine, altered mental status, request for epidural analgesia and hepatic disorders will be excluded from the study. The enrolled women will be divided into two groups by simple randomization with a 1:1 allocation ratio. The following will be done to all participants: - Informed written consent: after discussing the nature of the study as well as the expected value, outcome, and possible adverse effects. - Full medical history: including full obstetric history and current pregnancy history (entailing the 1st day of LMP). - Thorough Clinical Examination: general (vital signs) and full obstetric examination. - Obstetric ultrasonography: to confirm gestational age and the eligibility of the current pregnancy to participate in the study. This will be a double blinded study, blindness will be achieved by the following: the allocation treatment will be written on cards that will be sealed in sequentially numbered envelopes. The envelopes will be opened at the time of allocation after the enrolled participants will complete all baseline assessments. Group I comprised 30 women who will receive 10 ml of lidocaine 2% for perineal infiltration at the time of crowning while 30 women of Group II will have lidocaine prilocaine cream 15gm application on the perineum at 8 cm of cervical dilatation and then additional dose every 1 hour until delivery is achieved, then another dose of the cream will be applied before repairing the episiotomy and finally daily 3 doses every 8 hours at the site of episiotomy for the first week post-partum. Lidocaine prilocaine cream, an eutectic mixture, is composed of Lidocaine-25 mg, Prilocaine-25 mg, Arlactone 289 -19 mg, Carbopol-10 mg, Sodium hydroxide to make a pH of 9.6 mg and purified water to produce l gram. Fifteen grams of this cream will be applied as a thick layer (about 2 g/ 10 cm2 area) to the intact surface of the perineum and will be covered with an occlusive dressing (Kumar et al., 2015). In previous study done by Nirmala et al., 2013 The mean pain scores in the study were comparable for both groups, in our study we will increase the dose and the intervals of the applied cream and we will write down the results regarding pain score and side effects. At the time of crowning, the occlusive dressing and any residue of the cream will be removed and episiotomy will be done. The request for additional anesthetic agent (10 ml of 2% lidocaine solution for both groups) will be honored and recorded for both groups. And if the patient require additional analgesia during episiotomy (VAS more than 3) we will give additional anesthetic agent (10 ml of 2% lidocaine solution. After repair of episiotomy, each patient will be asked to grade the severity of pain during perineal repair on a Visual Analog Scale (VAS). The far left will be labelled 'No pain' and the far right will be labelled as 'worst pain possible'. The subject will be asked to make a vertical mark on this line reflecting the severity of pain. The patients are followed 6-week post-partum at the OPC or by telephone call to check the pain score by using (Very satisfied - satisfied - not satisfied - dissatisfied). Post-operative analgesics will include Paracetamol mainly and adjuvant NSAIDs as mentioned in the step ladder pain management by the WHO. If any further analgesia needed we will use Pethidine as a rescue analgesics as it is safe after delivery but we will prescribe anti emetic with pethidine as it will induce nausea and vomiting. Pain score during episiotomy repair will be the primary outcome of the study. Secondary outcome measures will include pain score in the first six weeks post-partum, dyspareunia and reduction of the rate of wound infection.

Outcome

Type Measure Description Time frame Safety issue
Primary Effect of the Intervention on pain score during the repair of episiotomy Efficacy of lidocaine-pridocaine cream in pain control for episiotomy incision and repair assessed by Visual Analogue Score VAS during episiotomy incision and repair where the minimum value is equal to zero which means no pain at all and the maximum value is equal to 10 and this means the worst pain ever. 1 year
Secondary Effect of the Intervention on pain score and dyspareunia during 6 weeks postpartum Pain score and dyspareunia in the first week post-partum and 6 weeks post-partum will be assessed by Customer Satisfaction Score or CSAT score, where the minimum value is very unsatisfied and associated with the highest degree of pain and the maximum value is very satisfied and this associated with the lowest degree of pain in the period of 1 week and 6 weeks. 1 year
Secondary Effect of the Intervention on perineal infection during 6 weeks postpartum Detection of the infection rates 6 weeks post-partum as this is the period of perpurium when puerperal sepsis may develops. 1 year
