A Study Comparing the Use of Deep or Standard Neuromuscular Blockade in Combination With Low or Standard Insufflation Pressures in Participants Undergoing Laparoscopic Cholecystectomy (P07982)

Gallbladder Disease Clinical Trial

Official title:
Randomized, Controlled, Parallel-Group, Double-Blind Trial to Compare the Use of Deep or Standard Neuromuscular Blockade in Combination With Low or Standard Insufflation Pressures Using a 2x2 Factorial Design in Patients Undergoing Laparoscopic Cholecystectomy (Protocol No. MK-8616-076-03 Also Known as SCH 900616, P07982)

Status Completed

Clinical Trial Summary

The purpose of this pilot study is to compare the use of deep or standard neuromuscular blockade (NMB) in combination with low or standard insufflation pressure in participants undergoing a surgical procedure, laparoscopic cholecystectomy. Insufflation refers to the injection of carbon dioxide into the abdomen during the laparoscopic surgery, to allow visualization of and access to the surgical field. The primary hypothesis of the study is that the use of sustained deep NMB improves the surgeon's overall satisfaction with surgical conditions as compared to standard NMB. The in-patient surgery is performed on Day 1 and the participant remains hospitalized for at least 48 hours following the surgery (or at least 24 hours following the surgery, if local practice does not allow 48 hours of hospitalization post surgery). On Day 8, a follow-up visit/contact including all participants occurs.

Clinical Trial Description

During procedure, surgeon (who was blinded to random assignment) could request that unblinded anesthetist change the randomized treatment conditions (called a "rescue intervention"), if surgeon considered surgical conditions to be unacceptable. This was to be done systematically as follows: If the participant is on standard NMB, the preferred rescue intervention should be to increase the NMB to a depth of 1-2 PTCs; for such a participant the second option (if participant is also on low insufflation pressure) should be the increase of insufflation pressure by 4 mmHg. If the participant is already on deep NMB, the preferred option should be (if participant is also on low insufflation pressure) the increase of insufflation pressure by 4 mmHg. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
