Changes of End-tidal Carbon Dioxide Tension during Laparoscopic Cholecystectomy

Abstract
|
|
|
Laparoscopy with peritoneal carbon dioxide(CO2) insufflation is frequently used in cholecystectomy instead of traditional open cholecystectomy and extended to hemicolectomy, because laparoscopic cholcystectomy has the advantages of shorter
hospital
stay, more rapid return to normal activities, and less pain associated with the small, limited incisions. But it also disadvantages buy pneumoperitonium such as its related hemodynamic and blood gas changes.
To investigate these hemodynamic changes of laparoscopic surgery, the authors observed the changes in blood pressure(systole, diastole, mean), heart rate, end tidal CO2 tension(PETCO2), PaCO2 and PaO2 just before CO2 insufflation and at 5, 10,
20,
30,
40, 50 and 60 minutes, after CO2 insufflation during general anesthesia with controlled ventilation (tidal volume: 10ml/kg, ventilatory rate: 10 breaths/min).
@ES The results were following:
@EN 1) mean arterial pressures were increased until 30 minutes after CO2 insufflation (P<0.05). Heart rate was not cheanged significantly throughout the operation.
2) PETCO2 was increased until 60 minutes after CO2 insufflation(P<0.01) but PaO2, was not decreased significantly throughtout the operation.
In conclusion, laparoscopy with CO2 insufflation has some effects on hemodynamic changes of cardiopulmonary and neuroendocrinologic system and it is recommended to hyperventilation under the careful mornitoring of PETCO2, PaCO2 and blood pressure
for
preventing hypercarbia.
