Abstract:
Objective To observe the effect of propofol target-controlled infusion on stress response during nasoscopic procedures.Methods Totally 40 patients with ASA gradesⅠ-Ⅱ scheduled for the nasoscopic operation ware randomly divided into two groups:Group A(propofol continuously injection,2.5 mg?kg-1,n=20)and Group B(propofol target-controlled infusion,4 ?g?ml-1,n=20).The operations were all performed under general anesthesia.Venous blood samples were taken to measure cortisol and blood glucose at three time points:before operation,at 30 min after the operation started,and 60 min after the endotracheal catheter was withdrawn.Meanwhile,HR and MAP of the patients were recorded.Results At both 30 min after the operation started and and 60 min after the endotracheal catheter was withdrawn,Group A showed significantly higher MAP and serum levels of glucose and cortisol than Group B.At 30 min after the operation started:HR:(73?8)/min vs(65?13)/min,t=2.344,P=0.024;MAP:(74?7)mm Hg vs(68?7)mm Hg,t=2.711,P=0.010;blood glucose:(6.28?0.11)mmol/ml vs(5.31?0.15)mmol/ml,t=23.321,P=0.000;cortisol:(125.3?11.5)ng/ml vs(89.6?9.9)ng/ml,t=10.521,P=0.000.At 60 min after the endotracheal catheter was withdrawn:MAP:(79?6)mm Hg vs(73?8)mm Hg,t=2.683,P=0.011;blood glucose:(6.18?0.09)mmol/ml vs(5.62?0.16)mmol/ml,t=10.082,P=0.000;cortisol:(169.1?16.3)ng/ml vs(149.5?15.3)ng/ml,t=3.921,P=0.000.Conclusion Propofol target-controlled infusion can inhibit the stress response caused by nasoscopic operation.
