摘 要:目的观察腰丛-坐骨神经阻滞与蛛网膜下腔阻滞用于膝关节结核手术的效果。方法选择我院2014年4月至2015年2月择期行膝关节结核手术的患者40例,按随机数字表法分为腰丛一坐骨神经阻滞组(A组)与蛛网膜下腔阻滞组(B组),每组20例。记录两组术中不同时间点,即阻滞前(To)、阻滞后5min(T1)、15min(T2)、30min(T3)血压变化、心率情况,感觉神经和运动神经阻滞起效和持续时间。采用SPSS11.0统计学软件进行分析,计量资料以“x±s”表示,组内各时点参数比较采用单因素方差分析,组间参数采用两独立样本t检验,计数资料采用y。检验。P〈0.05为差异有统计学意义。结果阻滞后,B组患者收缩压(SBP)、舒张压(DBP)均下降[SBP:T0为(133±14)mmHg(1mmHg=0.133kPa),Tl为(108±9)mmHg,T2为(113±15)ramHg,T3为(116±15)1TimHg(F=13.442,P=0.000);DBP:T1为(77±8)mmHg,T1为(68±5)mmHg,T2为(67±9)mmHg,L为(66±8)mmHg(F=8.264,P-0.000)]。阻滞后,A组患者各时间点SBP、DBP均高于B组,两组比较差异有统计学意义[A组T1时SBP为(134±20)mmHg(与B组比较,t=5.519,P=0.000),DBP为(78±10)mmHg(与B组比较,t=3.848,P=0.000);T2时SBP为(133±19)mmHg(与B组比较,t=3.701,P=0.001),DBP为(79±lO)mmHg(与B组比较,t=3.101,P=0.004);L时SBP为(130±23)mmHg(与B组比较,t=2.398,P=0.022),DBP为(80±10)mmHg(与B组比较,t=4.898,P=0.000)]。阻滞前后,两组心率(HR)比较差异均无统计学意义[A组:T。为(74±9)次/min,T1为(73±10)次/min,T2为(74±6)次/min,T3为(74±14)次/min(F=0.015,P=0.998);B组:T0为(73±9)次/min,T1为(73±9)次/min,T2为(72±5)次/rain,T3为(74±13)次/min(F=0.093,P=0.964)]。A组感觉神经阻滞起效时�Objective To compare lumbar plexus combined with sciatic nerve block anesthesia to subarach- noid block anesthesia in knee joint tuberculosis surgery. Methods Forty patients admitted in our hospital and un- derwent knee joint tuberculosis operation were randomly diveded into the umbar plexus combined with sciatic nerve block anesthesia group (group A, n= 20) and the subarachnoid block anesthesia group (group t3, n= 20) during Apr. 2014 to Feb. 2015. Blood pressure, heart rate, the time for Sensory nerve and motor nerve anesthesia taking effect onset and duration were recorded at the pre-block (%) and 5 rain (T1), 15 min (T2) and 30 min (Ta) after block in two groups. Using SPSS 11.0 statistical software for analysis, Measurement data recorded as mean + standard deviation (x±s). The parameters of each group at each time point were analyzed with one-way anova and parameters of groups were analyzed with independent t-test by SPSS 11.0 statistical software. Enumeration data were analyzed with Chi square test. P〈0.05 was considered statistically significant. Results After block anes- thesia, the BP including systolic blood pressure (SBP) and diastolic blood pressure (DBP) of patients in group B got decreased BP (SBP:T0 : (133±14) mm Hg,T1 : (108±9) mm Hg,T2 : (113±15) rnm Hg,T3 : (116±15) mm Hg, F=13. 442,P=0. 000;DBP: To : (77±8) mm Hg,T1 : (68±5) mm Hg,T2 : (67±9) mm Hg,T1: (66+_8) mm Hg, F=8. 264,P=0. 000)) ,SBP and DBP in group A were higher than those in group B (T1 :SBP: (134+-20) mm Hg, t=5. 519,P=0. 000,DBP: (78±10) mm Hg,t=3. 848,P=0. 000;T2 :SBP: (133+19) mm Hg, t=3. 701,P= 0.001,DBP: (79±10) mm Hg, t=3.10,P=0.004;Ta:SBP: (130±23) mm Hg, t=2.398,P=0. 022, DBP: (80±10) mm Hg, t = 4. 898, P= 0. 000). HR (times/min) in both groups were stable (group A: To : (74 ± 9) times/min,T1: (73±10) times/min, T1 : (74±6) times/min, T3
