Effects of Dexmedetomidine hydrochloride combined with Butorphanol tartrate on stress state in elderly patients with severe illness / 中华老年医学杂志

ABSTRACT

Objective To investigate the effect of Dexmedetomidine hydrochloride combined with Butorphanol tartrate on stress state in elderly patients with severe illness.Methods A total of 120 elderly patients with severe illness admitted into our hospital from March 2016 to March 2018 were randomized into group A,B and C(n=40,each).Group A was given intravenous Midazolam for analgesia,group B was treated with intravenous Medetomidine for analgesia,and group C received Dexmedetomidine combined with Butorphanol tartrate for analgesia.The differences in mean artery pressure(MAP),heart rate(HR),C-reaction protein(CRP),interleukin-6 (IL-6),visual analogue scale (VAS)score and Ramsay score were compared among the three groups.Results The levels of MAP,HR,CRP,IL-6 and VAS score after 24,48 and 72 hours of combined treatment of dexmedetomidine and butorphanol tartrate were lower in group C than in group B(P ＜0.05).There was no significant difference in the levels of MAP,HR,CRP,IL-6 and VAS score between group A and B after 24,48 and 72 hours of administration(P＞0.05).Ramsay score was higher in group C (intravenous both Dexmedetomidine and Butorphanol tartrate) than in group B (intravenous Dexmedetomidine alone)at 24,48 and 72 hours after administration (P ＜ 0.05).There was no significant difference in Ramsay score after 24,48 and 72 hours of administration between group A and B(P＞0.05).The incidence of adverse reactions was lower in group C than in group A and B(10.0％ vs.35.0％ and 32.5％,x2 =7.168 and 6.050,P =0.007 and 0.014).There was no significant difference in the incidence of adverse reactions between group A and BCx2=0.056,P =0.813).Conclusions Dexmedetomidine hydrochloride combined with Butorphanol tartrate can effectively improve hemodynamics,and alleviate inflammatory reaction and pain in elderly patients with severe illness,with a good security.And it is worthy of clinical generalization.
