Abstract:
Objective:To analyze the sedative effect of dexmedetomidine in the elderly patients with intraspinal anesthesia .Meth-ods:Totally 52 elderly patients with intraspinal anesthesia were randomly divided into the observation group (26 cases) and the control group (26 cases).After anesthetized successfully , the patients in the control group were given normal saline with intravenous pum-ping,while those in the observation group were given dexmedetomidine with intravenous pumping .The levels of blood pressure , RR, SpO2and HR, the Ramsay sedation score and the adverse reactions of the two groups before anesthesia (T0),10 min after anesthesia (T1),30 min after anesthesia (T2),60 min after anesthesia (T3) and at the end of operation (T4) were compared.Results:The lev-els of RR, SpO2 and HR in the two groups were maintained within the normal range , while the levels of SBP ,HR at T2 and T3 were sig-nificantly lower than those at T 0 in the observation group , and also lower than those at the same time point in the control group ( P<0.05).The Ramsay sedation score from T2 toT4 were significantly lower than that at T0 in the observation group, and also lower than that at the same time point in the control group (P<0.05).The incidence of adverse reactions in the observation group was obviously lower than that in the control group .Conclusion: Dexmedetomidine used in the elderly patients with intraspinal anesthesia can keep hemodynamic stability and exhibits adequate sedation with significantly reduced adverse reactions , which is worthy of clinical promo-tion.
