Deep versus moderate muscle relaxation during hysterectomy

The Effect of Deep Versus Moderate Neuromuscular Blocking on Patients Undergoing Open Hysterectomy

Not applicable Interventional Menoufia University · NCT07485517

This study will test whether using deep versus moderate muscle relaxation during elective hysterectomy changes surgical conditions, opioid requirements, and blood inflammation markers for women having the operation.

What this trial studies

Women scheduled for elective hysterectomy at a single center will receive either deep or moderate neuromuscular blockade during their operation, and perioperative management will follow standard protocols. Investigators will compare changes in serum inflammatory cytokines from preoperative baseline and measure total intraoperative fentanyl and postoperative morphine use. Secondary outcomes include postoperative pain scores and surgeons' subjective ratings of the surgical field. Eligibility is limited to ASA I–II patients with BMI under 35, excluding those with neuromuscular disorders, severe anemia, autoimmune disease, or on immunosuppressants.

Who should consider this trial

Good fit: Women scheduled for elective hysterectomy who are ASA I–II with BMI <35 and without neuromuscular, autoimmune, or uncontrolled medical conditions are the intended participants.

Not a fit: Patients with neuromuscular disorders, severe anemia, autoimmune disease, or on immunosuppressant therapy are excluded and would not be expected to benefit from this protocol.

Why it matters

Potential benefit: If successful, using deeper neuromuscular blockade could improve surgical conditions, reduce opioid consumption, and lower postoperative inflammatory markers after hysterectomy.

How similar studies have performed: Prior work in laparoscopic surgery has shown that deep neuromuscular blockade can improve operating conditions and sometimes reduce opioid needs, but its specific effects on inflammatory cytokines in hysterectomy are less well established.
