NCT Number: NCT01191476
This study is being performed to compare the cost of anesthetic techniques with sevoflurane (low fresh gas flow balanced anesthesia) versus propofol (target controlled infusion [TCI]) versus propofol induction and sevoflurane maintenance anesthesia in subjects undergoing elective laparoscopic surgery with predicted anesthesic use between 1 and 3 hour duration.

Three hundred thirty-six subjects were enrolled in this study. Two subjects, one treated with propofol for induction and maintenance and one treated with propofol for induction and sevoflurane for maintenance are not included in the study participation since no information was available for these two subjects.
Healthy volunteers accepted: No
Only the study team can determine whether someone qualifies for participation.
Inclusion criteria
Exclusion criteria
Sevoflurane was administered at a concentration of 8% via vital capacity induction and sevoflurane 0.8-1.5 minimum alveolar concentration (MAC) with a rate of 1 L/min fresh gas flow for maintenance.
Other names: ABT-941, sevoflurane, Ultane, Sevorane, Sevofrane
Propofol IV 4 ug/mL was administered with target controlled infusion (TCI) for induction and propofol 3 to 6 ug/mL was administered with TCI for maintenance.
Other names: Propofol
Propofol was administered as a bolus IV dose of 1.5 mg/kg for induction at a rate of 40 mg/10 seconds. During maintenance, a sevoflurane concentration of 0.8-1.5 minimal alveolar concentration (MAC) was administered at a rate of 1 L/min fresh gas flow.
Other names: ABT-941, sevoflurane, Ultane, Sevorane, Sevofrane
Time frame: Anesthetic Duration between 1 to 3 Hours
[Cost of VIMA = unit price of sevoflurane X used volume of sevoflurane];
[Cost of TIVA = unit price of propofol X total volume of propofol in the syringe];
[Cost of Propofol Induction and Sevoflurane Maintenance = unit price of propofol X total volume of propofol in the syringe + unit price of sevoflurane X volume of sevoflurane in the syringe].
The total volume of propofol in the syringe was calculated, even if all the anesthetic was not used, because it could not be reused.
Time frame: Up to 10 minutes
Loss of consciousness was measured from the time the anesthetic was administered until loss of consciousness (no response to command) occurred. Inhalational induction was induced with sevoflurane via vital capacity induction at 8%. Intravenous induction was induced with propofol at 4 µg/mL via target controlled infusion (TCI). In subjects who received both anesthetic agents, a bolus dose of propofol 1.5 mg/kg was used for induction.
Time frame: Every minute after anesthesia was stopped until the subjects' eyes opened
Measured from the time sevoflurane or propofol administration was stopped until the subject's eyes were opened. The investigator tapped the subject on the forehead or shoulder after anesthesia was stopped and asked them to open their eyes. This process was repeated approximately every minute until eye opening occurred.
Time frame: Every minute after anesthesia was stopped until extubation occurred
Time to extubation was measured from the time sevoflurane or propofol administration was stopped until tracheal extubation occurred. Criteria to determine extubation included a train of four stimulus > 0.9 (a method to measure the magnitude and type of neuromuscular block, a ratio of the fourth response to the first one), a tidal volume > 5 mL/kg, minute ventilation > 3 L, a respiratory rate of > 10 breaths/minute, an end tidal carbon dioxide < 45 mmHg, and eye opening has occurred.
Time frame: Every minute after anesthesia was stopped until orientation occurred
Time to orientation was measured from the time sevoflurane or propofol administration was stopped until orientation (able to state their name and date of birth).
