ABSTRACT

Objective To investigate the effects of muscle relaxant antagonism on patients with residual paralysis in postanesthesia care unit (PACU).Methods The similar patients who were daily accepted into PACU were chosen to make pairs,and were randomly divided into experimental (J; n =26) and control (F; n =26) groups.On arrival to the PACU,the train-of-four ratio (TO-Fr) was assessed using electromyography.When TOFr reached 4,Grour J was given with neostigmine 40 μg/kg and atropine 20 μg/kg; Group F was given with 5ml saline.Extubation was determined with standard clinical criteria.We recorded TOFr,PaO2,PaCO2at the time point of extubation,SpO2 at the time point of left the PACU,the stay time in PACU,the incidence of respiratory dysfunction,and the side effect.Results The TOFr at the time point of extubation in group J (0.96 ± 0.04) was significantly higher than group F (0.92 ±0.06) (P ＜0.05).The stay time in PACU in group J [(26 ±5)min] was significantly less than group F [(33 ±7) min] (P ＜ 0.01).PaO2,PaCO2,extubation time,and SpO2 were no significant difference between two groups (P ＞ 0.05).Two patients in group F had respiratory dysfunction.There was no incidence of postoperative nausea,vomiting,and other side effects in two groups.Conclusions Regular muscle relaxant antagonism lowered the risk of postoperative residual muscle relaxant effect,shortened the PACU residence time,and had no postoperative nausea and vomiting(PONV) and other side effects.
