Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study was to demonstrate in patients with myasthenia gravis (MG) undergoing thoracoscopic thymectomy faster recovery from a moderate neuromuscular block induced by rocuronium after reversal at reappearance of T2 by 2.0 mg/kg sugammadex compared to 50 ug/kg neostigmine.

Methods: A total of 64 patients with MG undergoing thoracoscopic thymectomy will be randomly divided into two groups: Sugammadex group (S group) and Neostigmine group (N group). The same anesthesia methods will be applied in both groups. Patients of S group will receive a dose of 2.0 mg/kg sugammadex after the last dose of rocuronium, at reappearance of T2. Patients of N group will receive a dose of 50 ug/kg neostigmine after the last dose of rocuronium, at reappearance of T2. The primary endpoint is time from start of administration of sugammadex or neostigmine to recovery of train-of-four stimulation ratio (TOFr) to 0.9. Secondary end points include time from start of administration of sugammadex or neostigmine to recovery of TOFr to 0.8 and 0.7, time to extubation, clinical signs of neuromuscular recovery, hemodynamic changes after muscle relaxation antagonism, adverse effects, time to operating room (OR) discharge, time to post-anesthesia care unit (PACU) discharge, and pulmonary complications within 7 days after the operation.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Due to neuromuscular transmission and functioning deficits, patients with myasthenia gravis (MG) are at increased risk of postoperative residual curarization (PORC), and may even develop into postoperative myasthenia crisis (PMC), which is a serious complication after thymectomy and increases the risk of death, with an incidence of up to 18.2%.

Effective reversal of neuromuscular blockade is crucial to ensure patient safety, reduce the incidence of PORC or PMC and prompt postoperative recovery. Traditionally, neostigmine, an acetylcholinesterase inhibitor, can be employed for neuromuscular blocking agent (NMBA) reversal. However, neostigmine is associated with potential drawbacks, such as delayed recovery and adverse muscarinic side effects.

Sugammadex, a selective relaxant binding agent, represents a relatively new alternative for NMBA reversal, specifically designed to encapsulate and inactivate aminosteroid NMBAs. The clinical benefits of sugammadex have been documented in several studies, demonstrating faster reversal of neuromuscular blockade and more predictable recovery profiles compared to neostigmine. However, the use of sugammadex in patients with MG remains an area of limited evidence. To date, to the best of our knowledge, there is a lack of prospective research to elucidate the application value of sugammadex in thymectomy in patients with MG.

This study is a prospective randomized controlled trial aimed at exploring the efficacy and safety of sugammadex compared to neostigmine for the reversal of neuromuscular blockade in patients with myasthenia gravis after thoracoscopic thymectomy.

Blinding Strategy

Participants Investigators Outcome Assessors
The doctors making the follow-up assessment were unaware of the treatment received, and none of the doctors who administered the injections carried out the follow- up evaluations. Thus, both the patients and the assessing doctors were remained unaware of the treatment received throughout the trial
