Brief Summary
In laparoscopic cholecystectomy, overall pain is a conglomerate of three different and clinically separate components: incisional pain (somatic pain) due to trocar insertion sites, visceral pain (deep intra abdominal pain), and shoulder pain due to peritoneal stretching and diaphragmatic irritation associated with carbon dioxide insufflation. Moreover, it has been hypothesized that intense acute pain after laparoscopic cholecystectomy may predict development of chronic pain (e.g., postlaparoscopic cholecystectomy syndrome). Without effective treatment, this ongoing pain may delay recovery, mandate inpatient admission, and thereby increase the cost of such care. Recently, the uses of peripheral axial blocks that deliver local anesthetic into the transversus abdominis fascial plane have become popular for operations that involve incision(s) of the abdominal wall. Thus, the Transversus Abdominis plane (TAP) block has been shown to reduce perioperative opioid use in elective abdominal surgery, including open appendicectomy, laparotomy, and laparoscopic cholecystectomy. However, the efficacy of the TAP block is reportedly only reliable in providing analgesia below the umbilicus. The ultrasound-guided subcostal transversus abdominis (STA) block is a recently described variation on the TAP block which produces reliable supraumbilical analgesia. Deposition of local anesthetic in this plane has shown to block dermatomes T6 to T10 with an occasional spread to T12. This variant will be discussed in our study. Currently, the Quadratus Lumborum block (QL block) is performed as one of the perioperative pain management procedures for all generations (pediatrics, pregnant, and adult) undergoing abdominal surgery. The local anesthetic injected via the approach of the posterior QL block ( QL 2 block ) can more easily extend beyond the TAP to the thoracic paravertebral space or the thoracolumbar plane, the posterior QL block entails a broader sensory-level analgesic and may generate analgesia from T7 to L1. Use of posterior QL block in laparoscopic cholecystectomy has not been investigated before and it is the variant that will be discussed in our study.

Study Arms (3)
Quadratus lumborum block Group (QL)
EXPERIMENTALQuadratus lumborum block will be performed
Transversus abdominis plane Group (TAP)
EXPERIMENTALSubcostal transversus abdominis plane will be performed
Control group (C)
EXPERIMENTALPostoperative analgesia will be accomplished with conjunction of paracetamol and ketorolac
Interventions
20 mL of 0.375% isobaric bupivacaine for each side deposited at the posterior aspect of the quadratus lumborum muscle (QLB type 2) using ultrasound after induction of general anesthesia and 15 minutes before start of surgery
20 mL of 0.375% isobaric bupivacaine for each side using ultrasound after induction of general anesthesia and 15 minutes before start of surgery
Paracetamol infusion (15 mg.kg) will be given by intravenous infusion after induction of general anesthesia.
In PACU Ketorolac 30 mg ampoule will be given by intravenous infusion to all cases and then every 8 hours.
With induction of general anaesthesia, fentanyl (1 microgram.kg) will be given. Intraoperatively, Fentanyl boluses (0.5 microgram.kg) will be given in case of increase in intraoperative mean arterial blood pressure or heart rate of more than 20% of baseline for longer than 5 minutes. Postoperatively, Fentanyl boluses (20 micrograms) will be given if VAS is more than 3 and it might be repeated after 30 minutes until VAS is ≤ 3.
