A Protocol on Comparative Evaluation of Epidural and Spinal Technique of Labour Analgesia in Rural Women of Central India and their Perceptions Regarding Pain Relief in Labour

Abstract

Background: Labour pain while giving birth is one of the most excruciatingly painful and emotionally stressful experience for a woman that has piqued the interest of several academicians. Labour pain is induced due to the uterine ischemia, expansion of vagina and birth canal, muscle contractions, and pressure on the bladder. To relieve the severe pain during labour, analgesia is required, which offers pain relief without the loss of consciousness. Regional analgesia (Epidural and spinal) are most commonly used for offering pain relief to women. Aim: To evaluate whether low dose spinal analgesia is a better alternative to lumbar epidural analgesia for pain relief in labour. Objectives - Primary objective is to evaluate efficacy of lumbar epidural and spinal analgesia for pain relief in labour. Secondary objective is to evaluate the perceptions of women towards the use of labour analgesia, to evaluate the maternal and fetal outcome and to evaluate the barriers affecting the use of lumbar epidural and spinal analgesia for women during labour. Methods: In this randomized control trial study, where 60 patients are present in each group. Patients in GROUP E, epidural analgesia will be given using 18-gauge Touhy epidural needle by a loss of  resistance  to air technique, and after confirmation of space, an epidural catheter will be inserted cranially in L3 - L4 or L4-L5 interspace, and a dose of 15ml of 0.125% bupivacaine with 25µg of fentanyl would be given slowly. Group S patients will receive subarachnoid block using 25-gauge needle inserted and directed to reach the intrathecal space between L3 - L4 or L4 - L5 intervertebral space. After a successful Dural puncture with acceptable CSF flow, 0.1% bupivacaine 2ml with 25µg fentanyl will be given via spinal needle. Throughout the duration of delivery, hemodynamic monitoring including SPO2, ECG, heart rate and blood pressure of mother and fetal heart rate would be monitored under the guidance of obstetrician and anesthesiologists. Patient will be assessed every 5min for the first 15 min, and then every 15 minutes until additional analgesia was requested. The severity of labour pain would be assessed using visual analogue scale. (0 = no pain; 10 = severe pain). Within the first 24 - 48 hours postpartum patient will fill the self-administered questionnaires. Results: The groups are expected to be similar. However, Low dose spinal analgesia may be a better alternative to lumbar epidural analgesia in providing effective pain relief for women in labour in terms of cost effectiveness. There are no results found as it is just a protocol. Results are yet to come. Conclusions: The study would offer new insights and knowledge into the use of epidural and spinal analgesia in India, particularly Wardha. The perceptions of women, towards labour analgesia, its consequences or side effects, and the myths associated with its use will be comprehended.
