Transversus Abdominis Plane Block Versus Wound Infiltration for Pulmonary Function Preservation Following Laparoscopic Living Donor Nephrectomy

Israel80 participantsStarted 2026-01-01

Plain-language summary

This study compares two pain control techniques in patients undergoing laparoscopic kidney donation surgery: transversus abdominis plane (TAP) block versus wound infiltration with local anesthetic. Postoperative pain can impair breathing by causing patients to take shallow breaths to avoid discomfort. This study will evaluate which technique better preserves lung function, specifically peak expiratory flow (PEF), after surgery. Eighty patients will be randomly assigned to receive either a TAP block (injection of local anesthetic into the abdominal wall muscles before surgery) or wound infiltration (injection of local anesthetic at the incision sites at the end of surgery). Both patients and the staff measuring outcomes will be blinded to group assignment. The primary outcome is the percentage change in PEF from before surgery to discharge from the recovery room. Secondary outcomes include pain scores, opioid use, breathing complications, and length of hospital stay.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.

Inclusion Criteria: * Patients who are scheduled to undergo elective LLDN. * Age above 18 years. * Body Mass Index (BMI) above 20 and below 40 kg m-2. * Eligible to sign informed consent. Exclusion Criteria: * Open or hand-assisted surgery. * Known cardiac or pulmonary disease. * Preoperative chronic pain (i.e., fibromyalgia, chronic neuropathic pain). * Contraindication for regional analgesia (i.e., known allergy to LA, skin lesions in the injection site). * Known allergy to one or more of the components of multimodal analgesia (i.e., opioids, paracetamol, tramadol, dipyrone). * Preexisting severe pulmonary disease (i.e., an obstructive lung disease with a forced expiratory volume in the first second \[FEV1\] below 49%, restrictive lung disease with a forced vital capacity \[FVC\] below 49%, pulmonary hypertension). Discontinuing criteria: Participants will be excluded from the analysis if they: * Experience intraoperative bleeding requiring transfusion of more than three units of blood products. * Experience hemodynamic instability requiring postoperative vasopressor or inotropic support. * Require conversion to open surgery. * Require mechanical ventilation after being transferred from the OR to the PACU.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
