Prospective Randomized Trial of Moderate vs Deep Neuromuscular Blockade During Laparoscopic Ventral Hernia Repair
The proposed study aims to assess the effect of different levels of muscle relaxation on the success of low-pressure insufflation, surgical conditions and patient recovery following laparoscopic repair of a ventral hernia (VHR) between 2 and 10cm in diameter. Patients will be randomized to moderate (TOF 1-2) or deep (post tetanic count 1-2) relaxation.
Specific Aim 1. Compare two different modes of neuromuscular blockade (moderate and deep) on the ability to maintain low insufflation pressure during laparoscopic VHR. All procedures will start with low-pressure insufflation (8 mm Hg). Surgeon assessment of the conditions will be serially performed during surgery on an established visual scale. If conditions are deemed less than adequate (score 1-2), insufflation pressure will incrementally increase up to 15 mm Hg. Outcome for this specific aim will be the mean insufflation pressure during each procedure, and the ability to perform low-pressure laparoscopic VHR.
Specific Aim 2. Evaluate the success of moderate neuromuscular blockade on the ability to maintain good conditions (visual scale grade 4 or 5) for each. Surgical conditions will be considered successful when scores are maintained at 4 or 5 throughout the duration of the procedure. Outcome for this aim will be the mean score for surgical condition assessment for each procedure, using a previously published surgeon-driven scoring system (score 4-5 will be used as a surrogate of good visualization).
Specific Aim 3. Assess patient recovery with low and high insufflation pressures during laparoscopic VHR. Patient overall satisfaction with recovery, pain level, pain medication requirement, PONV incidence and severity will be assessed in multiple time points following surgery. Outcomes for this aim will be mean pain (visual scale), PONV severity (analogue score) and incidence (binary outcome), and patient satisfaction using the QoR-15 survey. Assessments will be performed at 30 minutes, 1, 12 and 24 hours following surgery.

---|---|
Kokeellinen: Moderate Neuromuscular Block
Train of four count of 1-2.
All procedures will start with low-pressure insufflation (8 mm Hg).
Surgeon assessment of the conditions will be serially performed during surgery on an established visual scale.
If conditions are deemed less than adequate (score 1-2), insufflation pressure will incrementally increase up to 15 mm Hg.
Reversal of muscle relaxation will be performed at the end of the procedure using established medications used in clinical practice.
In theory, deep relaxation may require a more prolonged reversal process, but using contemporary medical agents (sugammadex), reversal from deep relaxation is prompt (2-3 minutes) without any additional delays.
|
All procedures will start with low insufflation pressure (8 mmHg).
Surgical field assessment (scale 1-5) will be performed every 5 minutes (Martini Br J Anaesth 2014).
If conditions are poor (rating 1-2), intraperitoneal insufflation will be incrementally increased (10 mmHg, 12 mmHg, 15 mmHg) every 5 minutes as needed.Reversal of muscle relaxation will be performed at the end of the procedure using established medications used in clinical practice.
In theory, deep relaxation may require a more prolonged reversal process, but using contemporary medical agents (sugammadex), reversal from deep relaxation is prompt (2-3 minutes) without any additional delays.
