Abstract

PURPOSE: To analyze hemodynamic parameters of electrical bioimpedance on increased blood pressure induced by pneumoperitoneum and compare hemodynamic effects of propofol and isoflurane during laparoscopic cholecystectomy.
METHODS
Systemic vascular resistance index(SVRI), index of contractility(IC), end diastolic index(EDI), mean arterial pressure(MAP) and heart rate(HR) were measured after anesthetic induction, 5, 10, 15 and 30 minutes after CO2 insufflation and after CO2 removal.
RESULTS
In isoflurane group, MAP, IC, SVRI were increased but EDI was decreased after induction of pneumoperitoneum. In propofol group, MAP, SVRI were increased but IC was decreased after induction of pneumoperitoneum. HR was not changed during operartion.
CONCLUSION
After induction of pneumoperitoneum, MAP is increased by increased IC and SVRI in isoflurane. In case of propofol, the MAP is increased by increased SVRI. It seems that increased transmural pressure of lymphatics and splanchnic vasculatures rather than sympathetic stimulation increases SVRI after pneumoperitoneum.
