091Fertility&Health临床用药不同剂量右美托咪定预防痔切除术患者单次腰麻后寒战的效果分析王娜高攀赵燕殷萌保定市第一中医院麻醉科，河北保定071000【摘要】目的：分析不同剂量右美托咪定预防痔切除术患者单次腰麻后寒战的效果。方法：选取于2021年6月—2022年8月期间到本院行痔疮切除术的患者作为样本来开展本次研究，样本例数64例，在单双号分发法的指导下将这64例患者进行分组，其中32例单号患者为常规组，另外32例双号的患者为研究组，两组患者均采用0.75%的布比卡因进行单次腰麻，之后常规组患者采用0.4μg·kg-1的右美托咪定进行微量泵注射，研究组患者采用0.6μg·kg-1的右美托咪定进行微量泵注射，并分析其临床疗效。结果：研究组患者的寒战发生率明显低于常规组（P<0.05）；研究组和常规组的生命体征指标都较为稳定（P>0.05）。结论：对于痔切除术患者来说，在为其进行单次腰麻后应采用0.6μg·kg-1的右美托咪定进行微量泵注射，这有助于改善患者的生命体征指标，降低患者发生寒战的风险，应用效果十分显著。【关键词】不同剂量；右美托咪定；痔切除术；单次腰麻；寒战；效果；分析EffectofdifferentdosesofdexmedetomidineonpreventingshiveringaftersinglespinalanesthesiainpatientsundergoinghemorrhoidectomyWANGNa,GAOPan,ZHAOYan,YINMengDepartmentofAnesthesiology,BaodingFirstHospitalofTraditionalChineseMedicine,Baoding,Hebei071000,China【Abstract】Objective:Toanalyzetheeffectofdifferentdosesofdexmedetomidineonpreventingshiveringaftersinglespinalanesthesiainpatientsundergoinghemorrhoidectomy.Methods:PatientswhounderwenthemorrhoidectomyinourhospitalfromJune2021toAugust2022wereselectedassamplestocarryoutthisstudy,thenumberofsampleswas64.Undertheguidanceofthesingleanddoublenumberdistributionmethod,these64patientsweredividedintogroups,ofwhich32patientswithsinglenumberwereintheroutinegroupand32patientswithdoublenumberwereinthestudygroup.Patientsinbothgroupsweregivenasinglespinalanesthesiawith0.75%bupivacaine,andthenpatientsintheroutinegroupwereinjectedwithasinglespinalanesthesiaof0.4μg·kg-1dexmedetomidinebymicropump,andpatientsinthestudygroupwereinjectedwith0.6μg·kg-1dexmedetomidinebymicropumpanditsclinicalefficacywasanalyzed.Results:Theinciden...
