ABSTRACT
Objective:
To evaluate the effects of lotensin on sympathetic responses following cervical plexus block and to explore the mechanism of cardiovascular responses and sympathetic nervous system activity according to plasma catecholamine concentration.Method:
Sixty adult patients were randomly divided into two groups (n = 30)Group A and group B. In group B lotensin 0.15mg/kg was taken orally at night before surgery and 2h before anesthesia separately. Hemodynamics was determined before anesthesia(T_1), 5min(T_2), 10min(T_3), 15-20min(T_4)and 30min (T_5) after cervical plexus block. For measurement of plasma catecholamine concentration, blood was collected at T_1,T_3,T_4 and T_5. The study was finished before beginning of surgery and infusion.Result:
In group A after anesthesia SP,DP, MAP,HR,RPP and plasma noradrenalinc level rose markedly(P0.05). All parameters were lower in group B compared with group A(P
