No results posted yet for this study

Summary

The study aims to compare the efficacy of the external oblique plane block and the subcostal plane block in providing pain relief during perioperative anaesthetic management. As intraoperative haemodynamic stability is an important factor for surgeons to achieve better outcomes due to its effect on the quality of laparoscopic intervention, the investigator will observe its impact on this matter.

Ninety patients scheduled for elective surgery will be randomly assigned by a closed-envelope method into three groups (n = 30) receiving either a subcostal plan block, an external oblique plane block, or a control block preoperatively. Each group receive standardised general anaesthesia and perioperative pain management protocol. The data to be recorded include a numeric rating scale, intraoperative and postoperative analgesic use, intraoperative haemodynamic parameters, and VAS score. Moreover, block performance time, motor block and side effects or complications will be noted.

Conditions

  • Peripheral Nerve Block
  • Cholecystectomy, Laparoscopic
  • Pain After Surgery

Interventions

PROCEDURE

External Oblique Intercostal Plane Block

Right after general anaesthesia induction and patient intubation, the patient will be placed in a supine position. Following sterile skin preparation, an external oblique plane block will be performed by the same anesthesiologist under ultrasound guidance, using an external oblique muscle approach. A 22-gauge, 50-mm insulated stimulating needle will be used to administer 20 mL of anaesthetic solution (0.25% bupivacaine, 20 mL). Finally, 20 mL of local anaesthetic solution (0.25% bupivacaine anaesthetic solution) will be administered to disperse within the external oblique space.

PROCEDURE

Subcostal TAP block and spinal anesthesia group (STAP)

Right after general anaesthesia induction and patient intubation, the patient will be placed in a supine position. Following sterile skin preparation, a subcostal block will be performed by the same anaesthesiologist under ultrasound guidance with a subcostal approach. A 22-gauge, 50-mm insulated stimulating needle will be used to administer 20 mL of anaesthetic solution (0.25% bupivacaine, 20 mL). Finally, 20 mL of local anaesthetic solution (0.25% bupivacaine anaesthetic solution) will be administered to disperse within the subcostal space.
