Transversalis fascia plane block to reduce opioid use after hand-assisted laparoscopic kidney donation

The Effects of Transversalis Fascia Plane Block on Opioid Consumption in Patients Undergoing Hand-Assisted Laparoscopic Donor Nephrectomy: A Randomized Controlled Prospective Study

Not applicable Interventional Koç University · NCT07396753

This will try an ultrasound-guided transversalis fascia plane block to see if living kidney donors have less pain and need fewer opioid pain medicines after hand-assisted laparoscopic donor nephrectomy.

What this trial studies

In this single-center, prospective randomized controlled trial at Koç University Hospital, adults approved for living kidney donation and scheduled for hand-assisted laparoscopic donor nephrectomy will be randomized to receive an ultrasound-guided transversalis fascia plane block with local anesthetic or standard care. The primary outcome is total opioid consumption in the first 24 hours after surgery, with secondary outcomes including numeric rating scale pain scores and opioid-related side effects. The block is performed preoperatively under ultrasound guidance to inject local anesthetic into the transversalis fascia plane of the lower abdominal wall. Key exclusions include chronic opioid use, allergy to local anesthetics, major organ dysfunction, ASA physical status III or greater, and inability to provide informed consent.

Who should consider this trial

Good fit: Adults approved for living kidney donation who are scheduled for hand-assisted laparoscopic donor nephrectomy, can give informed consent, and do not have chronic opioid use or contraindications to local anesthetics are ideal candidates.

Not a fit: Patients with chronic opioid use, allergy to the study medications, major organ dysfunction, ASA III or higher, or those unable to consent are unlikely to receive benefit from this intervention in the trial.

Why it matters

Potential benefit: If successful, the block could lower postoperative pain and opioid use, speeding recovery and reducing opioid-related side effects for living kidney donors.

How similar studies have performed: Regional abdominal nerve blocks have reduced pain and opioid use in other lower abdominal surgeries and some reports support TFPB for similar procedures, but high-quality evidence specifically for hand-assisted laparoscopic donor nephrectomy is limited.
