目的观察全麻诱导前肌肉注射不同剂量右美托咪定(dexmedetomidine,DEX)对芬太尼诱发咳嗽反射的影响。方法200例美国麻醉医师协会(ASA)分级Ⅰ-Ⅱ级择期手术患者,完全随机分为对照组(c组)和DEX组(D1组、D2组、D3组)4组,每组50例。诱导前D1组、D2组、D3组分别肌肉注射DEX1、1.5、2IAg/kg,C组肌肉注射等容量的生理盐水。15min后静脉注射芬太尼3μg/kg,过1min后静脉注射异丙酚2mg/kg、罗库溴铵0.6mg/kg行快速诱导气管插管。记录注射DEX前(R)、注射芬太尼前(T1)、插管前即刻(T2)、插管后即刻(T3)、插管后1min(T4)、插管后3min(T5)、插管后5min(T6)的收缩压(systolic blood pressure,SBP)、舒张压(diastolic blood pressure,DBP)、平均动脉压mean artery pressure,MAP)、心率(heart rate,HR)以及咳嗽反射情况。结果D1组、D2组、D3组咳嗽反射的发生率(分别为8%、6%、4%)明显低于c组(32%)(P〈0.01);D。组、D:组、D3组之间咳嗽反射的发生率比较差异无统计学意义(P〉0.05);各组T1时点MAP、HR[(89±10)、(91±11)、(94±9)、(90±9)mmHg(1mmHg=0.133kPa),(68±9)、(70±10)、(68±8)、(70±12)次/min]与T0时点MAP、HR[(9±8)、(89±10)、(92±8)、(88±9)mmHg,(73±11)、(74±9)、(71±7)、(72±8)次/min]比较差异无统计学意义(P〉o.05);与Tn时点MAP、HR[(91±8)、(89±10)、(92±8)、(88±9)mmHg,(73±11)、(74±9)、(71±7)、(72±8)次/rain]比较,各组T2时点MAP、HR[(80±8)、(78±10)、(71±9)、(69±9)mmHg,(64±9)、(65±10)、(58±7)、(56±8)次/min]明显降低(P〈0.05);T2时点D2组、D3组MAP、HR[(71±9)、(69±9)mmHg,(58±7)、(56±8)次/min]低于C组、D1组[(80±8)、(78±10)mmHg,(64±9)、(65±10
Objective To investigate the effect of pretreatment of intramuscular dexmedetomidine(DEX) on the incidence of fentanyl-induced cough on general anesthesia patients. Methods 200 patients, ASA I -H ,were randomly allocated into four groups (group C, Dl, D2 and D3, n=50). Patients in group DI, D2 and D3 were administered intramuscularly DEX 1,1.5,2 μg/kg, respectively, and the patients in group C were injected with an isovolumic saline. 15 rain later, all patients of the 4 groups received intravenous fentanyl 3 μg/kg, and 1 min subsequently, propofol 2 mg/kg and rocuronium 0.6 mg/kg were injected intravenously for anesthetic induction. Noninvasive blood pressure and heart rate were recorded at the following time points: before DEX administration (T0), before fentanyl administration(T1), instantly before intubation(T2), instantly after intubation(T3), 1 min after intubation(T4), 3 rain after intubation (Ts), and 5 min after intubation (T6). The incidence and severity of cough within 1 rain after fentanyl administration were also recorded. Results The incidences of cough in group D1, D2 and D3 were 8%, 6% and 4% respectively, which were significantly lower than that in group C(32%)(P〈0.01 ), while there were no remarkable differences among group D1, D2 and D3(P〉0.05 ). Among the four groups, there were no significant differences in mean artery pressure(MAP) and heart rate(HR) at T1 compared with those at T0[ (89±10), (91±11), (94±9), (90±9) mm Hg( 1 mm Hg=0.133 kPa). (68±9), (70±10), (68±8), (70±12) bpm vs (91±8), (89±10), (92±8), (88±9) mm Hg. (73±11), (74±9), (71±7), (72±8) bpm ](P〉0.05). MAP and HR at T2 were lower than those at To among the four groups[(80±8 ), (78±10), (71±9), (69±9) mm Hg. (64±9), (65±10), (58±7), (56±8) bpm vs (91±8), (89±10), (92±8), (88±9) mm Hg. (73±11), (74±9), (71±7�
