ABSTRACT

Objective. To evaluate the measurement of oxygen consumption (VO2), carbone dyoxide production (VCO2) and energy expenditure (EE), usign two different procedures.
Design. Clinical prospective comparative study.
Setting. An anesthesiology deparment and an inhalotherapy department of a teaching hospital of Mexico City.
Patients. Twenty two adult patients undergoing to laparoscopic surgery.
Interventions. Eleven patients (group 1) received sevoflorano plus fentanyl 2-5 mg/kg/h and balanced general anesthesia; other eleven patients (group 2) were treated with a single dose of sevoflorano and fentanyl, 2 mg/kg and inhalated general anesthesia.
Measurements and principal results. VO2 was increased in both groups, 199 ± 59 mL/min in group 1 and, 268 ± 56 mL/min; in group 2 p ‹ 0.01). VCO2 was 194 ± 54 mL/min (group 1) and 257 ± 71 mL/min (group 2); p ‹ 0.003. EE was 1421 ± 317 kcal/24 h (group 1) vs 1923 ± 495 kcal/24 h (group 2); p ‹ 0.01).
Conclusion. The use of fentanyl in continuos infusion probably avoids the increasing of VCO2 during the recovery period of adult patients undergoing to laparoscopic surgery.
