Background: For elective cesarean birth, the anesthetic technique of preference is neuraxial anesthesia (primarily spinal anaesthesia). Adequate postsurgical analgesia is a key component of ERAS protocols; it's much more important for women who are having a cesarean birth, and it's quickly acquiring popularity.
Aim of the Work: The purpose of this study is to assess the effectiveness of quadrates lumborum plane block versus Erector Spinae Plane Block as a post-operative analgesic following cesarean section.
Patients and Methods: A prospective randomized controlled single-blinded clinical research study on 50 patients aged 22 to 35 years old was conducted at Al-Azhar University hospitals in Cairo. After receiving institutional ethics committee approval, she was scheduled for an elective cesarean birth under spinal anesthesia without any other surgical intervention like tubal ligation or ovarian cyst removal.
Results: the results of this study showed that QLB and ESB provide a good analgesic effect in patients undergoing caesarean section. In terms of duration of analgesia and total analgesic consumption, the Erector spinae block performed better than the QLB, but there was no statistically significant difference with P= 0.158, P= 0.179, respectively.
Conclusion: Ultrasound guided quadratus lumborum and erector spinae blocks provide effective modality for control of postoperative pain associated with caesarean section. Ultrasound guided erector spinae block is superior to ultrasound guided quadratus lumborum block in respect of pain ratings, duration of analgesia, and overall analgesic consumption but without a statistically significant difference.
