About this study

Official title: Pharmacokinetics and Pharmacodynamics of Sugammadex in Reversal of Vecuronium-induced Neuromuscular Blockade in Anesthesia Obese Patients Undergoing Bariatric Surgery

The purpose of this study is to illustrate pharmacokinetics and pharmacodynamics of sugammadex in reversal of vecuronium-induced neuromuscular blockade in anesthesia obese patients undergoing bariatric surgery.

Read the detailed description

16 obese patients undergoing bariatric surgery were divided into 2 groups according to body mass index (BMI), including obese group (O group, n=8, 25≤BMI≤39.9kg/m²) and morbidly obese group (M group, n=8, BMI≥40kg/m²).

Vecuronium was continuous infusing to maintain moderate neuromuscular blockade during the laparoscopic surgery and stopped infusing after the laparoscopic procedure. A single dose administration of sugammadex (Sug) 2.0mg/kg according to ideal body weight (IBW) was given at the reappearance of the second twitch of the train-of-four (TOF) response.

On one hand, venous blood samples were obtained before administration of Sug and at 2, 3, 5, 10, 15, 20, 30, 60 minutes and 2, 4, 6, 8 hours after administration of Sug to determine plasma concentration of Sug using HPLC-MS. On the other hand, time from start of administration of Sug to recovery of TOF ratio to 0.9 and other clinical indicators were also recorded.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sugammadex in people with Pharmacokinetics and Pharmacodynamics, run by Guangzhou General Hospital of Guangzhou Military Command at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 31 Mar 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Plasma Concentration of Sugammadex (time frame: 0, 2, 3, 5, 10, 15, 20, 30, 60 minutes and 2, 4, 6, 8 hours). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT04131218, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 31 Mar 2020; AzTrials last refreshed its copy on 8 Nov 2026.
