Clinical trial of cis-atracurium in the treatment of patients with hysteroscopic surgery
Objective To explore the influence of intravenous injection of cis-atracurium during anesthesia induction on QT interval(QTc),hemodynamics and oxidative stress level in patients undergoing hysteroscopic surgery.Methods Patients undergoing hysteroscopic surgery were classified into control group and treatment group.The treatment group was given intravenous injection of 2 mg·kg-1 of propofol emulsion injection+3 μg·kg-1 of fentanyl+0.15 mg·kg-1 of cis-atracurium besylate for injection,while the control group was given intravenous injection of 2 mg·kg-1 of propofol emulsion injection+3 μg·kg-1 of fentanyl+the same amount of 0.9％NaCl as treatment group.Laryngeal mask was placed in the two groups after 3 min,and laryngeal mask ventilation was given for general anesthesia.QTc value and hemodynamics[mean arterial pressure(MAP)]were detected before entering the room(T0),after 1 min of propofol+fentanyl intravenous injection(T1),after 1 min of cis-atracurium besylate for injection/0.9％NaCl(T2),immediately after laryngeal mask insertion(T3)and after 3 min of laryngeal mask insertion(T4).The anesthetic effect,postoperative dynamic pain visual analogue scale(VAS)score and sore throat were counted.The levels of serum oxidative stress indicators[superoxide dismutase(SOD),malondialdehyde(MDA)]at T0 and at the end of surgery(T5)were detected,and the safety was assessed.Results Fifty-two cases in treatment group and forty-four cases in control group were included.There was no statistical difference in QTc value between treatment group and control group at T0-T4(all P＞0.05).The MAP values in treatment group and control group at T3 were(84.22±5.96)and(86.78±6.11)mmHg,respectively,with a statistical difference(P＜0.05).The laryngeal mask insertion times in treatment group and control group were(17.02±2.47)and(19.52±2.34)s;the spontaneous breathing recovery times were(8.51±1.84)and(6.18±1.15)min;the eye opening time were(10.49±2.42)and(9.53±2.17)min;the laryngeal mask removal time were(11.16±2.16)and(10.21±2.34)min;the incidence rates of postoperative sore throat were 13.46％and 31.82％,and the differences were statistically significant(all P＜0.05).The levels of SOD in treatment group and control group at T5 were(36.63±4.17)and(33.26±4.86)nU·mL-1;the levels of MDA were(7.42±2.14)and(8.59±2.83)mmol·L-1(all P＜0.05).The adverse drug reactions in treatment group were mainly nausea and vomiting,respiratory depression and hypotension,and the adverse drug reactions in control group were mainly nausea and vomiting and respiratory depression.The incidence rates of adverse reactions in treatment group and control group were 13.46％and 11.36％,respectively(P＞0.05).Conclusion Cis-atracurium intravenous injection during anesthesia induction has no influence on QTc in patients undergoing hysteroscopic surgery,and has advantages in stabilizing intraoperative hemodynamics,reducing postoperative sore throat and improving serum oxidative stress indicators.
