Abstract:
ObjectiveTo investigate the effects of different carbon dioxide pneumoperitoneum pressure on the arterial blood gas, hemodynamics and stress status of patients treated with laparoscopic gynecological surgery.
MethodsNinety patients scheduled by laparoscopic gynecological surgery were divided into the group A, group B and group C according to the random number table method(30 cases in each group).During laparoscopic gynecological surgery, the group A, group B and group C were inflated with 11 mmHg, 13 mmHg and 15 mmHg of carbon dioxide pneumoperitoneum pressure, respectively.The arterial blood gas index, heart rate(HR), mean arterial pressure(MAP), central venous pressure(CVP), peripheral vascular resistance(SVR), cardiac output(CO), and serum levels of orepinephrine(NE), cortisol(COR) and prostaglandin E2(PGE2) in three groups were recorded at 5 min after anesthesia, 5 min after aeration, 15 min after aeration and 5 min after pneumoperitoneum stop.
ResultsThe levels of PaCO2, HR, MAP, SVR, COR, NE and PGE2 in group C were significantly higher than those in group A and group B at 5 min and 15 min after inflation(P < 0.05 to P < 0.01), and the levels of CVP and CO were significantly lower than those in group A and group B(P < 0.01).The level of HCO3- in group C at 15 min after inflation was significantly lower than those in group A and group B(P < 0.01).
ConclusionsThe medium and low carbon dioxide pneumoperitoneum pressure has little effect on the arterial blood gas, hemodynamics and stress status of patients treated with gynecological laparoscopic surgery, which is suitable for gynecological laparoscopic surgery.
