About this study

Official title: Pulmonary Function, Muscle Strength, Time to Extubation and Quality of Recovery in the Post Anesthesia Care Unit After Reversal of Neuromuscular Blockade With Neostigmine or Sugammadex.

Read the detailed description

Sugammadex has been shown to have a faster onset and more reliable reversal of neuromuscular blockade when compared to neostigmine as measured by return of Train-of-four (TOF) ratio to >0.9. (Breuckmann, 2015) The investigator's hypothesis is that sugammadex will be associated with improved deep breathing as measured by incentive spirometry in the PACU. The investigators also hypothesize that patients reversed with sugammadex will have shorter times to extubation and better recovery profiles in the PACU as measured by strength, PACU discharge readiness and quality of recovery scores.

Residual neuromuscular blockade after surgery can result in airway compromise, pulmonary complications, and possible need for reintubation and can be a negative experience for patients. Reintubation after surgery is currently a quality measure in NSQIP (National Surgery Quality Improvement Program) A TOF ratio of <0.9 has been identified as a marker of residual neuromuscular blockade in the PACU. (Farhan 2013) Several clinical trials have shown that reversal of neuromuscular blockade with sugammadex results in a faster and more reliable return to TOF ratio of >0.9 when compared to neostigmine. However most of these studies primarily report on TOF ratios. There are scant data on clinical outcomes after reversal with neostigmine versus sugammadex. Incentive spirometry is a clinically meaningful measurement of postoperative pulmonary function, i.e the ability to breath deeply, which minimizes atelectasis and risk of postoperative pneumonia.

The investigators will compare recovery profiles of patients who have received sugammadex or neostigmine for reversal of neuromuscular blockade after surgery. The primary outcome will be incentive spirometry volumes after surgery as a measure of pulmonary function. The secondary measures include hand grip measured using a dynamometer, time to extubation, time to PACU discharge, time to sit independently, and quality of recovery 15 survey scores.

This will be a single-center, prospective, randomized, assessor blinded, controlled trial. Patients will be randomized to either receive sugammadex or neostigmine for the reversal of neuromuscular blockade. The anesthesiologist will be unblinded to the study drug however the assessor in the PACU will be blinded.

What is being measured

The primary outcome is the main question the study is designed to answer.

Incentive Spirometry, Change From Baseline and Recovery Profile - 30 Minutes
Incentive spirometry measurements will be done at 30, 60 and 120 minutes after surgery. The change from baseline and recovery profile will be measured.
Measured: 30 Minutes
Incentive Spirometry, Change From Baseline and Recovery Profile - 60 Minutes
Incentive spirometry measurements will be done at 30, 60 and 120 minutes after surgery. The change from baseline and recovery profile will be measured.
Measured: 60 Minutes after reversal
Incentive Spirometry, Change From Baseline and Recovery Profile - 120 Minutes
Incentive spirometry measurements will be done at 30, 60 and 120 minutes after surgery. The change from baseline and recovery profile will be measured.
Measured: 120 minutes after reversal

Secondary outcomes (7)

Grip Strength, Change From Baseline and Recovery Profile 30 Min
Grip strength will be measured with a hand dynamometer
Measured: 30 minutes
Grip Strength, Change From Baseline and Recovery Profile 60 Min
Grip strength will be measured with a hand dynamometer
Measured: 60 minutes after reversal
Grip Strength, Change From Baseline and Recovery Profile 120 Min
Grip strength will be measured with a hand dynamometer
Measured: 120 minutes after surgery
Time to Extubation
Measured time between surgery end and time of extubation (removal of breathing tube)
Measured: Immediately after surgery, up to 30 minutes
Train of Four Ratio > 90% During PACU Admission
Train of four ratio (TOFR) is the ration of the twitch height of the 4th twitch compared to the 1st twitch during train of four neuromuscular stimulation. This measurement was performed using a TOF Watch, which in an accelemyographer. Electric current is applied to the ulnar nevre and the twitches are measured in the thumb. Adequate reversal of neuromuscular blockade is defined as a TOFR >90%.
Measured: At PACU admission, approximately within one hour of reversal of neuromuscular blockade reversal.
Quality of Recovery 15 Survey
15 question survey to assess patient's overall quality of recovery after anesthesia/surgery.
Quality of Recovery 15 Survey. Minimum: 0 Maximum: 150 Higher Scores mean a better outcome and better quality of recovery.
Part A: How have you been feeling in the last 24 hours? 0 = none of the time (poor), 10 = all of the time (excellent). Examples: able to breath easily, able to enjoy food, feeling rested. etc.
Part B: Have you had any of the following in the last 24 hours? 10 to 0, where 10 = none of the time (Excellent) and 0 = all of the time (poor). Examples: moderate pain, nausea or vomiting, feeling worried or anxious, etc.
Measured: Postoperative day number one
Time to Readiness for Post Anesthesia Care Unit (PACU) Discharge (Aldrete Score >9)
Measured time between PACU admission and meeting PACU discharge readiness. PACU discharge was defined as when the patient had an Aldrete score of 9 or higher as determined by the PACU nurse. The Aldrete score is a measure of post anesthesia recovery. 0 is poor condition and 10 is excellent condition. There are 5 assessment items (able to move voluntary, breathing, consciousness, circulation (BP) and spO2) which are graded on a 0-2 point scale with 0 being poor and 2 being excellent.
Measured: Within 4 hours from the end of surgery

Where is the study taking place?

The record lists 1 site in United States. 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?

Yes. Results are posted in the registry (first posted 22 May 2020). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Incentive Spirometry, Change From Baseline and Recovery Profile - 30 Minutes (time frame: 30 Minutes). The study lists 3 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 NCT02909439, which also lists 3 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 22 May 2020; AzTrials last refreshed its copy on 8 Nov 2026.
