Abstract:
Objective To explore the risk factors of shivering after intraspinal anesthesia.Methods 640 anesthesia recovery patients after intraspinal anesthesia from February 2011 to May 2015 were selected as the research subjects.According to whether patients appeared shivering,they were divided into research group and control group.The research group had 328 cases of appearing shivering,the control group had 312 cases without shivering. Basic clinical data of patients,operation time and blood loss,tympanic membrane temperature,anesthesia,anesthesia blocks plane indicators were compared to explore the risk factors of shivering after intraspinal anesthesia.Results This study included 640 cases,including 328 cases with chills reaction,the incidence rate was 51.25%.Single factor results showed that the low age,male,central cooler,surgery for a long time,the bleeding of more lumbar hemp,choice of anesthetic methods and anesthetic plane above T8 indicators, there were close relationship with shivering after intraspinal anesthesia,the differences between the two groups were statistically significant (χ2 =40.661,17.208, 32.369,32.931,36.624,14.844,26.84,all P<0.05).Multivariable logistic regression analysis results showed that age,gender,core body temperature,operation time,blood loss,spinal canal anesthesia methods and indexes of anes-thetic plane were important risk factors of chills reaction after anesthesia in patients with spinal canal anesthesia (OR=1.843,1.925,2.183,0.548,0.497,0.529,0.743,all P<0.05).Conclusion Male,younger age,operation for a long time,big intraoperative blood loss,tympanic membrane temperature low mode selection subarachnoid block anesthesia,and the anesthesia plane factor are the main risk factors of spinal canal anesthesia patients to appear chills response,the above factors are needed for close monitoring of patients with intraspinal anesthesia in the preoperative period.
