NCT06941259

Brief Summary

The goal of this double-blind randomized control clinical trial is to investigate the effectiveness of regional anaesthesia blocks (rectus sheath block and ilioinguinal nerve block) on pain management in patients undergoing hand assisted laparoscopic donor nephrectomy surgery. The main question it aims to answer is: Does combined rectus sheath block and ilioinguinal nerve block lower the amount of postoperative opioid consumption? Does reduced postoperative opioid consumption reduce the incidence of potential opioid related side effects? Does the application of nerve block affect length of hospital stay? Researchers will compare patients who had nerve blocks with regional anaesthesia to a placebo group to see if total postoperative opioid consumption. Participants will be randomly divided in two. Regional anaesthesia with local anaesthesia or a placebo will be performed. Patients will be followed 24 hours postoperatively to measure total opioid consumption. Possible side effects, complications and length of hospital stay will be noted.

Study Arms (2)

Group Sham

SHAM COMPARATOR

After the induction of general anaesthesia, the rectus sheath block and ilioinguinal nerve block will be performed to patients with a solution containing only physiological saline.

Procedure: Rectus sheath and ilioinguinal nerve block with physiological saline

ACTIVE COMPARATOR

After the induction of general anaesthesia, the rectus sheath block and ilioinguinal nerve block will be performed to patients with a solution containing 0.25% bupivacaine.

Procedure: Rectus sheath and ilioinguinal nerve block with local anaesthesia

The patient will be blind whether they receive local anaesthesia or physiological saline as the nerve block ingredient. The care providers will be blind to the solution when they are performing the regional anaesthesia. The care providers will be blind when they are monitoring the patient after surgery.
