Risk factors analysis for postoperative hypotension during the transition from recovery to transfer ward in patients undergoing general anesthesia
Objective To analyze the risk factors of post-surgery hypotension(PSH)in patients undergoing gen-eral anesthesia after surgery and to explore its predictive value for patients.Methods A total of 231 patients un-dergoing general anesthesia were recruited,and the following time points were observed for possible PSH occur-rence:at the end of surgery,1,3,5,10 min after crossing the bed,at the time of entering the resuscitation room,at the time of exiting the resuscitation room,and at the time of returning to the ward.Whether gender,age,body weight,BMI,underlying disease,anesthesia mode,operation method,intraoperative access quantity,BP,HR,RR,and SpO2 were the risk factors for the occurrence of PSH were also analyzed.Results The inci-dence of patients with PSH at each time point from the end of surgery to return to the ward was 29.44％,25.54％,20.35％,17.75％,16.45％,20.35％,and 22.94％,respectively.Compared with the time of ad-missionto the operating theatre,body weight,BMI,SBP,and DBP of the patients in the PSH group was statisti-cally different from the non-PSH group at the time of admission to the resuscitation room.Compared with the time of admissionto the operating theatre,bleeding volume,SBP,DBP and SpO2 of the patients in the PSH group was statistically different from the non-PSH groupat the time of admission to the ward.Multiple linear regression analy-sis showed that SBP were risk factors for PSH at the time of admission to the resuscitation room.Bleeding volume and SBP were risk factors for the occurrence of PSH when entering the ward;ROC curve analysis showed that SBP had good predictive value for the occurrence of PSH in patientsat the time of admission to the resuscitation room,the predicted value is 89.5 mmHg.Bleeding volume,and SBP had good predictive value for the occur-rence of PSH in patients after entering the ward.Conclusion SBP before operation and blood loss during opera-tion wererisk factors for PSH after general anesthesia,which have a good predictive value for the development of PSH in patients returning to the ward at the end of surgery,with a predictive value at 150 mmHg and 126.5 mm-Hg,respectively.
