Impact of Sugammadex Versus Neostigmine on Early Postoperative Pulmonary Function

China240 participantsStarted 2025-12-30

Plain-language summary

Residual neuromuscular blockade (NMB) after general anesthesia increases the risk of postoperative respiratory complications (atelectasis, pneumonia, re-intubation) and delays pulmonary function recovery. Sugammadex, a γ-cyclodextrin that directly encapsulates rocuronium, reverses NMB rapidly and completely without cholinergic side effects, whereas neostigmine requires co-administration of an antimuscarinic and may leave residual blockade. In this multicenter, randomized, double-blind, controlled trial, 240 adult patients (ASA I-III) undergoing elective thoracoscopic lung resection (≤ 1 segment) will be randomized 1:1 to receive sugammadex (2 mg/kg) or neostigmine (0.03 mg/kg) + atropine (0.015 mg/kg) at the end of surgery. The primary endpoint is the percent decline in forced expiratory volume in 1 second (FEV₁) at 1 hour post-extubation compared to preoperative baseline; a ≥ 5% improvement with sugammadex is hypothesized. Secondary endpoints include FEV₁ at days 1-3, pain scores, opioid consumption, gastrointestinal recovery, quality of recovery (QoR-15), neuromuscular monitoring (TOF ratio), and incidence of postoperative pulmonary and surgical complications.

Inclusion Criteria: * Scheduled for elective unilateral thoracoscopic partial lung resection, with expected resection not exceeding one lung segment. * Age between 18 and 80 years. * American Society of Anesthesiologists (ASA) Physical Status classification I-III. Exclusion Criteria: * Contraindications to drug use, such as history of allergy, epilepsy, angina, ventricular tachycardia; contraindicated in patients with mechanical intestinal obstruction or urinary tract obstruction; contraindicated in cases of arrhythmia, bradycardia (\<50 beats per minute), hypotension, or increased vagal tone; contraindicated in patients currently using depolarizing muscle relaxants (e.g., succinylcholine). * Inability to correctly cooperate with portable lung function testing. * Hepatic or renal insufficiency. * Pregnancy, lactation, potential for pregnancy, or planning pregnancy. * Preoperative history of drug abuse or addiction. * Second surgery during postoperative hospitalization. * Patients who refuse to participate. * Other situations deemed inappropriate by the investigators shall be accompanied by a statement of the reasons.

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.

What they're measuring

Change in Forced Expiratory Volume in 1 Second (FEV1) from Baseline to 1 Hour Postoperatively

Timeframe: Preoperative (baseline, within 7 days before surgery) and 1 hour postoperative.
