Summary

This study evaluates the effects of three different anesthetics on high dose rocuronium in laparoscopic cholecystectomy cases. Patients were randomly assigned to one of the propofol, desflurane, or sevoflurane groups. Train of four (TOF) and bispectral index (BIS) monitoring were used during surgery in all groups.Patients were followed until TOF and post tetanic count (PTC) values reached 1 and the time was recorded.The effect of three anesthetic drugs used on the duration of the muscle relaxant drug was investigated.

Detailed description

In recent years, studies have been published showing that by applying deep neuromuscular block during laparoscopic cholecystectomy, intraabdominal pressure can be reduced without compromising the surgical conditions, thus complications such as postoperative nausea and vomiting (PONV) and pain can be reduced. The results we obtained in our previous study showed that deep neuromuscular block achieved with a high dose of 1.2 mg/kg rocuronium allowed the operation to be performed with lower intra-abdominal pressure values, shortened the operation time, reduced PONV and pain in laparoscopic cholecystectomy cases. The most important factor affecting the depth of neuromuscular block is the dose of the neuromuscular agent. However, anesthetic agents can also affect the depth of neuromuscular blockade. The effects of muscle relaxants are enhanced when administered together with inhalation anesthetics.Propofol and sevoflurane are widely used in the maintenance of anesthesia. Unlike propofol, sevoflurane enhances the effects of some neuromuscular blocking drugs, including rocuronium. Our primary aim in this study is to evaluate the effects of sevoflurane, desflurane, or propofol, which are commonly used in anesthesia maintenance, on the duration of neuromuscular block caused by 1.2 mg/kg rocuronium, which is the dose we routinely use in anesthesia induction, in laparoscopic cholecystectomy cases. Secondary aims are to investigate its effects on intraabdominal pressures and surgical conditions, and to determine whether it reduces postoperative pain and PONV, as well as extubation and recovery times.
