Overview
Brief Summary
In this study, it was aimed to evaluate the effects of intrathecal morphine and posterior quadratus lumborum block (QLB2) on postoperative acute pain scores and opioid consumption in the first 24 hours after cesarean section.
Detailed Description
Postoperative acute pain following a cesarean section is sharp, well-localized, and highly intense. An ideal pain management approach after a cesarean section should provide high-quality analgesia with minimal side effects and facilitate the mother's rapid return to daily activities. Different options for pain control include central blocks, peripheral blocks, and systemic medications. Intrathecal morphine (ITM) administration is a widely used approach for post-cesarean pain management both globally and in our clinic. However, it can reduce patient satisfaction due to side effects such as nausea, vomiting, and itching. On the other hand, the Quadratus Lumborum Block (QLB), a type of peripheral block, has proven analgesic efficacy in controlling acute postoperative pain following a cesarean section. The aim of this study is to examine and compare the analgesic efficacy of intrathecal morphine (ITM) and Posterior Quadratus Lumborum in the management of acute postoperative pain after a cesarean section. This study is a single-center, double-blind, prospective observational study. Patients will be divided into 2 groups. Group 1: The group receiving intrathecal morphine (ITM) Group 2: The group receiving Posterior Quadratus Lumborum Block In elective cesarean section cases under spinal anesthesia, the patient group receiving ITM and posterior QLB will be evaluated for obstetric general well-being during the first 24 hours and at discharge. Total morphine consumption in the first 24 hours, Pain scores (NRS) at rest and during movement, presence of nausea-vomiting and itching, patient satisfaction and any potential side effects will be recorded through follow-up.

Outcomes
Primary Outcomes
Morphine consumption in the first 24 hours after surgery
Time Frame: Postoperative day 1
Morphine consumption in the first 24 hours will be measured by IV PCA. Patients will be able to request opioids via a PCA device when their NRS score is above 4
Secondary Outcomes
- Postoperative nausea and vomiting (PONV) scores(Postoperative Day 1)
- Postoperative pain scores(Postoperative day 1)
- Postoperative pruritus score(Postoperative Day 1)
- The number of patient required rescue analgesic(Postoperative Day 1)
- Patients' satisfaction and quality of pain management(Postoperative Day 1)
