Multimodal Anesthesia in Robotic Laparoscopic Nephrectomy (MANTRA)

23 aprile 2026 aggiornato da: Fundacio Puigvert

Efficacy of Multimodal Anesthesia in Robotic Laparoscopic Nephrectomy: Impact on Recovery and Early Hospital Discharge.

It is a prospective, randomized, controlled and superiority clinical trial, with the objective of comparing the effectiveness of multimodal anesthesia versus conventional anesthesia in patients undergoing oncological robotic nephrectomy within a short-stay surgery program (SSA). The effect of no specific drug will be evaluated, but rather the anesthetic approach ologies of surgical patients. The clinical trial will be carried out in a third-level university hospital, between the first half of 2026 and the second half of 2027 and, after approval by the corresponding Clinical Research Ethics Committee.

Panoramica dello studio

Descrizione dettagliata

Prospective, randomized, controlled clinical trial to evaluate whether multimodal anesthesia allows for early hospital discharge (reduce 24-hour admission) compared to conventional anesthesia in oncological robotic nephrectomies; both according to usual practice. The effect of no specific drug will be evaluated, but rather the anesthetic approach pologies of surgical patients. It will be enrolled 80 patients. Patients will be randomized 1:1 using a computer-generated sequence into: Group A: multimodal anesthesia vs Group B: conventional anesthesia.

Main objective is to demonstrate the superiority of multimodal anesthesia over conventional anesthesia in patients undergoing robotic laparoscopic nephrectomy within a short-stay surgical program, in terms of reducing hospital admission time and earlier discharge. To demonstrate that multimodal anesthesia allows a reduction in hospital admission time allowing for early discharge.

Estimated duration of the study is 18 months. This involves collecting data from preoperative to 30 days post-surgery from patients undergoing oncological robotic nephrectomy.
