The effects of dexmedetomidine and urapidil on postoperative extubation stress response,postoperative shivering,and cerebral oxygen metabolism in patients with hypertensive intracerebral hemorrhage
Objective To investigate the effects of dexmedetomidine and urapidil on postoperative extubation stress response,postoperative shivering,and cerebral oxygen metabolism in patients with hypertensive intracerebral hemorrhage.Methods A total of 120 patients with hypertensive intracerebral hemorrhage admitted to the Seventh People's Hospital of Hebei Province from January 2021 to December 2022 were selected as the research subjects.They were randomly divided into an observation group(60 cases)and a control group(60 cases)according to the random number table method.All patients underwent intracranial hematoma removal surgery under general anesthesia combined with bone flap decompression surgery for treatment.The observation group patients received sedation and analgesia with dexmedetomidine and urapidil after surgery,while the control group patients received sedation and analgesia with dexmedetomidine after surgery.The differences in vital signs,stress indicators,cerebral oxygen and cerebral glucose metabolism,and adverse reactions between two groups of patients were compared.Results There was no statistically significant difference in heart rate(HR),systolic blood pressure(SBP),diastolic blood pressure(DBP),and bispectral index(BIS)between the two groups after entering the room(T0)and before anesthesia medication(T1)(all P＞0.05).The HR,SBP,DBP,and BIS of the observation group were significantly lower than those of the control group at extubation(T2),immediately after extubation(T3),1 minute after extubation(T4),and 3 minutes after extubation(T5),and the differences were statistically significant(all P＜0.05).There was no statistically significant difference in various stress indicators between the two groups of patients at T0(all P＞0.05),while the stress indicators of the observation group were significantly lower than those of the control group at T5(all P＜0.05).There was no statistically significant difference in the cerebral oxygen uptake rate(CERO2)and cerebral arteriovenous blood glucose difference(AVDG)between the two groups of patients at T0(all P＞0.05),while the CERO2 and AVDG in the observation group at T5 were significantly higher than those in the control group(all P＜0.05).There was no statistically significant difference in the incidence of hypoxemia,hypotension,and bradycardia between the two groups of patients after surgery(all P＞0.05).The incidence of postoperative shivering in the observation group was lower than that in the control group(P＜0.05).The Glasgow Coma Index of both groups of patients after surgery was higher than that before surgery(all P＜0.05),and there was no statistically significant difference in Glasgow Coma Index between the two groups before and after surgery(all P＞0.05).Conclusions Dexmedetomidine and Urapidil have significant improvement effects on postoperative extubation stress response,postoperative shivering,and cerebral oxygen metabolism in patients with hypertensive intracerebral hemorrhage.It is recommended to promote them clinically.
