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)
17. september 2018 opdateret af: Merck Sharp & Dohme LLC
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)
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.

Detaljeret beskrivelse
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.

Eksperimentel: Standard NMB and Standard Insufflation Pressure
Treatment condition for this arm is Standard NMB (depth of blockade at a targeted Train of Four [TOF] ratio of 10%)/Standard insufflation pressure (starting pressure of 12 mmHg).
|
NMB will be induced by intravenous (IV) administration of a bolus dose of 0.45 mg/kg rocuronium.
NMB will be maintained using rocuronium infusion or additional bolus doses as needed for the management of NMB to the targeted depth according to the assigned treatment condition.
- Standard NMB - administration of neuromuscular blocking agent (NMBA) titrated to a depth of blockade at a targeted TOF ratio of 10% (range: TOF count 2-3 to TOF ratio of 20%).
- Deep NMB - administration of NMBA titrated to a targeted depth of 1-2 Post Tetanic Counts (PTCs) (range: 1-5 PTC).
Andre navne:
Insufflation (injection) of carbon dioxide will be used to induce pneumoperitoneum, which is presence of air or gas in the abdominal (peritoneal) cavity.
NMB will be reversed with IV administration of 2 or 4 mg/kg sugammadex (depending on the depth of NMB) according to the approved label for sugammadex.
