Deep versus Moderate Neuromuscular Blockade in Gynecologic Laparoscopic Operations: Randomized Controlled Trial

Area of Science:

• Anesthesiology
• Surgical Oncology

Background:

• Neuromuscular blockade (NMB) is crucial in laparoscopic surgery.
• Optimizing NMB depth is essential for patient outcomes.

Purpose of the Study:

• To compare deep versus moderate NMB during gynecologic laparoscopic surgery.
• To evaluate the impact on surgical conditions and postoperative pain.

Main Methods:

• Single-blind, randomized controlled trial.
• 144 patients assigned to deep (PTC 0-1) or moderate (TOF 0-1) NMB.
• Surgical conditions, pain scores, and analgesic consumption were primary outcomes.

Main Results:

• Surgical field scores were similar between deep and moderate NMB groups (2.68 vs. 2.44).
• Deep NMB significantly reduced postoperative pain (0.79 vs. 1.58) and analgesic consumption (4.1% vs. 18.3%).
• Fewer incidents of subcutaneous emphysema were observed in the deep NMB group.

Conclusions:

• Deep NMB does not enhance surgical conditions in gynecologic laparoscopy compared to moderate NMB.
• Deep NMB may reduce postoperative pain and opioid requirements.
• Deep NMB might decrease the incidence of subcutaneous emphysema.
