Effect of magnesium sulfate on muscle relaxation during surgery

Effect of Magnesium Sulphate Pretreatment on Cis-Atracurium Induced Neuromuscular Block and Recovery Characteristics: A Randomized Controlled Trial.

Phase2; Phase3 Interventional Assiut University · NCT05757999

What this trial studies

This study evaluates how magnesium sulfate affects the onset and duration of muscle relaxation induced by cis-atracurium in patients undergoing elective otorhinolaryngological surgery. Participants will be divided into two groups: one receiving magnesium sulfate and the other receiving saline as a comparator. The study aims to assess the impact of magnesium sulfate on neuromuscular blockade and the period of no response to nerve stimulation. By exploring this approach, the study seeks to enhance the efficacy of anesthesia while minimizing the required doses of other anesthetic agents.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18-60 scheduled for elective otorhinolaryngological surgery with a BMI between 18.5 and 24.9.

Not a fit: Patients with neuro-muscular diseases, renal or hepatic impairment, or those outside the specified age range may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved muscle relaxation during surgery, potentially enhancing patient safety and comfort.

How similar studies have performed: Previous studies have shown that magnesium sulfate can enhance the effects of neuromuscular blocking agents, indicating potential success for this approach.
