Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Sevoflurane
Subjects received sevoflurane, a inhalational (volatile) anesthetic, which was administered for induction and maintenance of general anesthesia.
Inhalational induction was induced via vital capacity induction at 8% and maintained at 0.8-1.5 minimum alveolar concentration (MAC).
|
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:
|
Active Comparator: Propofol
Subjects received propofol, an intravenous (IV) anesthetic, which was administered for induction and maintenance of general anesthesia.
|
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:
|
Active Comparator: Propofol Induction and Sevoflurane Maintenance
Subjects received a bolus dose of propofol of 1.5 mg/kg administered for IV induction followed by sevoflurane at 0.8-1.5 MAC for maintenance anesthesia.
|
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.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Cost of Volatile Induction and Maintenance Anesthesia (VIMA) With Sevoflurane, Total Intravenous Anesthesia (TIVA) With Propofol, or Intravenous Induction With Propofol and Inhalational Maintenance With Sevoflurane
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. |
Anesthetic Duration between 1 to 3 Hours
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Time to Loss of Consciousness
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.
|
Up to 10 minutes
|
Time to Eye Opening
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.
|
Every minute after anesthesia was stopped until the subjects' eyes opened
|
Time to Extubation
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.
|
Every minute after anesthesia was stopped until extubation occurred
|
Time to Orientation
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).
|
Every minute after anesthesia was stopped until orientation occurred
