Rocuronium Consumption in Etomidate-based and Propofol-based General Anesthesia Under Sevoflurane

March 16, 2016 updated by: Guolin Wang, Tianjin Medical University General Hospital

Consumption of Rocuronium Under Etomidate-based Versus Propofol-based Maintenance of General Anesthesia Under Different Concentration of Sevoflurane- BIS Guided Clinical Trial in a Closed Loop Infusion System

Different concentration of sevoflurane was given to maintain anesthesia. The dose of propofol to maintain BIS between 40-60 and the consumption of rocuronium was recorded and evaluated.

Study Overview

Detailed Description

2 age group of patients was selected, 40-60 years and above 60 years. Maintenance of anesthesia was carried out using different concentration of Sevoflurane, ie MAC 0.5, 0.75 and 1.0. Bis value was kept between 40-60 and the dose of propofol required was recorded. Rocuronium infusion given in a close loop infusion system for different group was tabulated. The results was then analysed.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: SP1- sevoflurane MAC 0.5
In this group, patient of age 40-60 years of age, ASA I/II, undergoing elective abdominal or gynecological surgery are chosen. Neuromuscular function prior to induction is assessed by acceleromyography by stimulation of ulnar nerve and noting the response of adductor pollicis. After induction and intubation, Sevoflurane is started to achieve the desired MAC of 0.5. Propofol infusion is started to keep BIS between 40-60.
0.5 MAC Sevoflurane
Propofol consumption
Consumption of Rocuronium
Experimental: SP2- Sevoflurane MAC 0.75
In this group, patient of age 40-60 years, ASA I/II, undergoing elective abdominal or gynecological surgery are chosen.Neuromuscular function prior to induction is assessed by acceleromyography by stimulation of ulnar nerve and noting the response of adductor pollicis. After induction and intubation, Sevoflurane is started to achieve the desired MAC of 0.75. Propofol infusion is started to keep BIS between 40-60.
