摘要
目的
     观察三种不同全麻方法复合硝普钠控制性降压时患者血流动力学的变化差异;研究三种不同全麻方法复合硝普钠控制性降压对机体肾功能的影响。
     方法
     选择择期口腔颌面部整形患者30例,ASAⅠ~Ⅱ级,随机分为三组:芬太尼复合异氟烷吸入麻醉组(Ⅰ组)、芬太尼和丙泊酚复合异氟烷吸入麻醉组(Ⅱ组)、瑞芬太尼复合丙泊酚全凭静脉麻醉组(Ⅲ组),每组各10例患者。三组均用硝普钠行控制性降压,将平均动脉压(mean arterial pressure,MAP)降低30%左右,维持40分钟以上。分别记录麻醉前(T_0)、麻醉后降压前(基础值,T_1)、降压后10分(T_2)、20分(T_3)、40分(T_4)、停止降压后2分(T_5)、5分(T_6)、10分(T_7)、15分(T_8)、20分(T_9)的收缩压(systolic blood pressure,SBP)、舒张压(diastolic blood pressure,DBP)、MAP、心率(heart rate,HR)、率压积(rate pressure product,RPP,即SBP×HR)、脉搏血氧饱和度(pulse oxygen saturation,SpO_2)、呼气末二氧化碳分压(end-tidal carbondioxide partial pressure,P_(ET)CO_2)。于T_1、T_4及T_7三个时间点,分别抽取病人动脉血标本5ml,采用放射免疫法检测血β_2-微球蛋白(β_2-MG)的水平。
     结果
     1、MAP:在停止降压后的T_5、T_7时,Ⅲ组明显低于Ⅰ组(P<0.05);T_6时,Ⅲ组明显低于Ⅰ组、Ⅱ组(P<0.05);与T_1相比,Ⅰ组患者的MAP在T_5、T_6、T_7、T_8时,均显著升高(P<0.05);Ⅱ组患者的MAP从T_6时开始升高,在T_7、T_8时均高于基础水平(P<0.05)。
     2、HR:控制性降压开始后T_2、T_3、T_4时,与T_1相比,三组的HR均升高(P<0.05);但Ⅲ组明显低于Ⅰ组、Ⅱ组(P<0.05)。
     3、RPP:在控制性降压开始后T_2、T_3、T_4时,直至停止降压后T_5、T_6、T_7时,与T_1相比,Ⅰ组、Ⅱ组患者的RPP均明显高于基础水平(P<0.05)。在控制性降压过程中,即T_2、T_3、T_4时,Ⅲ组患者的RPP明显低于Ⅰ组、Ⅱ组(P<0.05);在停止降压后T_5、T_6、T_7时,Ⅲ组患者的RPP仍明显低于Ⅰ组(P<0.05)。
     4、β_2-MG:与T_1相比,在T_4时三组患者的β_2-MG均有所升高,而在T_7时各组的β_2-MG均有所下降是但是各组的具体数值的变化没有显著性差异,为排除患者控制性降压之前血液内基础水平彼此各不相同的干扰以及保证科研统计数据时的同质化原则,将每个病人T_1、T_4、T_7彼此间的差值计算得出后再与其各自的T_1相比得出的比值记为变化率;即得到相应两时间点间的变化率(Rate ofChange,RC):RC01=(T_4-T_1)/T_1;以及相应两时间点间的变化率:RCO2=(T_1-T_7)/T_1分别表示排除患者自身控制性降压前的血液内基础水平彼此各不相同的干扰单纯比较各种麻醉方法的不同导致其控制性降压前后血液β_2-MG变化程度的大小。与T_1相比,在T_4时Ⅲ组患者的RC01均明显低于于Ⅰ组、Ⅱ组(P<0.05);在T_7时,Ⅲ组患者RCO2明显低于Ⅰ组、Ⅱ组(P<0.05)。
     结论
     全凭静脉麻醉下,即用丙泊酚-瑞芬太尼麻醉维持,使用硝普钠进行控制性降压能提供稳定的血流动力学状态;其控制性降压前后β_2-MG升高和降低的变化程度都比较缓和,从而减少控制性降压对围手术期机体的肾功能的影响,降低控制性降压对机体肾脏功能的干扰,提高患者肾脏对手术和应激刺激的耐受能力,降低术后肾脏可能发生肾功能损伤并发症风险的可能性,从而促进术后恢复。
Objective
     To study the effect of hemodynamics and the renal function made by combination of three different methods of general anesthesia with controlled hypotension with Sodium Nitroprusside(SNP).
     Methods
     Thirty patients,ASAⅠ~Ⅱ,scheduled for oral and maxillofacial plastic surgery, were randomly divided into three groups.All of them were under the condition of controlled hypotension induced by SNP.GroupⅠ:isoflurane-fentanyl group(n =10); groupⅡ:isoflurane-propofol-fentanyl group(n =10);groupⅢ:propofol-remifentanil group(n =10).The objectives of anesthesia were to reduce MAP by 30%and to maintain more than 40 minutes.Before anesthesia(T_0);before controlled hypotension (basic values,T_1);10 minutes(T_2),20 minutes(T_3),40 minutes(T_4)after controlled hypotension;2 minutes(T_5),5 minutes(T_6),10 minutes(T_7),15 minutes(T_8),20 minutes(T_9)after stopping controlled hypotension,to record the date of these parameters:systolic blood pressure(SBP),diastolic blood pressure(DBP),mean arterial pressure(MAP)and heart rate(HR),RPP(SBP×HR)value,pulse oxygen saturation(SpO_2),end-tidal carbon dioxide partial pressure(P_(ET)CO_2),rebound hypertension.Collected the arterial blood samples to assay the levels ofβ_2-MG by radioimmunoassay at T_1,T_4,T_7.
     Results
     1.MAP:In groupⅢ,MAP was significantly lower than groupⅠ(P<0.05)at T_5,T_7. In groupⅢ,MAP was significantly lower than that in groupⅠand groupⅡ(P<0.05)at T6.In group,MAP were significantly increased(P<0.05)than groupⅡat the T_5,T_6,T_7, T_8.In groupⅡ,MAP began to increase at T_6,and still higher than basic level(P<0.05) at T_7,T_8.
     2.HR:At T2,T3,T4,HR increased(P<0.05)in all three groups compared with T_1. But HR of groupⅢwas significantly lower than that of groupⅠand groupⅡ(P<0.05).
     3.RPP:In groupⅠandⅡ,RPP were significantly higher than the basic level (P<0.05)at T_2,T_3,T_4,T_5,T_6,T_7.In groupⅢ,RPP was significantly lower than that of groupⅠandⅡ(P<0.05)at T_2,T_3,T_4.In groupⅢ,RPP was still significantly lower than that of groupⅠ(P<0.05)at T_5,T_6,T_7.
     4.β_2-MG:At T_4,the level ofβ_2-MG was significantly higher than the basic level (P<0.05)at T_1 and at T_7 the level ofβ_2-MG was still significantly lower than the basic level at T_1 in all the three groups(P<0.05).There were no significantly differences of theβ_2-MG levels in each group at T_1,T_4,T_7.But in groupⅢ,the rate of change inβ_2-MG level was significantly lower than that of groupⅠ(P<0.01)and groupⅡ(P<0.05) at T_4;the rate of change inβ_2-MG level was significantly higher than that of groupⅠ(P<0.01)and groupⅡ(P<0.05)at T_7 In groupⅡ,the rate of change inβ_2-MG level was significantly lower than that of groupⅠ(P<0.05)at T_4 and higher than that of groupⅠ(P<0.05)at T_7 significantly.
     Conclusion
     Total intravenous anesthesia,which maintained by propofol and remifentanil and controlled hypotension induced by Sodium Nitroprusside,can provide the stable status of hemodynamics and reduce the influence on the renal function raise the tolerance of kidney on the stress of stimulations under the conditions of controlled hypotension in surgical operations.
