Abstract:
Objective To analyze effects of different anesthesia procedures on heart rate variability(HRV) as an index of autonomic nervous activity and hemodynamics during CO2 pneumoperitoneum pressure in laparoscopic cholecystectomy(LC).Methods 45 patients of ASA I or II phage scheduled for LC were divided into general anesthesia group(Group I,Control Group),general anesthesia combined with esmolol group(Group II) and general anesthesia combined with epidural block group(Group III) according to operation date.HRV,HR and MAP were measured before anesthesia(T1),before pneumoperitoneum(T2) and at 5 min(T3),10 min(T4),20 min(T5),30 min(T6) after pneumoperitoneum.Results As compared with pre-pneumoperitoneum(T2),low frequency(LF),low frequency/high frequency(LF/HF) in the Group I increased significantly(P0.05).Comparisons among the three groups,LF,LF/HF in the Group I at all time points after pneumoperitoneum were significantly higher than those in the II and III Group(P0.05).Conclusions Esmolol can relieve stress reaction induced by pneumoperitoneum,but it can't completely block increasing of sympathetic nerve activity;using general anesthesia combined with epidural block in LC can inhibit sympathetic nerve excitation,sustain automatic never stability.
