Anesthetic efficacy of lidocaine in patients undergoing painless ultrasonic gastroscopy
Objective To observe the anesthetic efficacy of intravenous injection of lidocaine in the patients undergoing painless ultrasonic gastroscopy.Methods Ninety patients undergoing painless ultrasonic gastroscopy were divided into two groups.Group L(49 cases)was intravenously injected with lidocaine 1.0 mg/kg,which was followed by lidocaine 1.0 mg·kg-1·h-1 intravenous infusion.Equal volume of normal saline was used in group C(46 cases)as the control.Then sufentanil 0.1 μg/kg and ciprofol 0.3～0.4 mg/kg were intravenously given in both groups,respectively.The consumption of ciprofol,awakening time,leaving operation room time and the adverse reactions were recorded.HR,MAP and SpO2 were recorded before anesthesia induction(T0),at the time of gastroscope probe passing through throat(T1),15 minutes after the beginning of gastroscopy(T2),at the end of gastroscopy(T3)and awakening(T4).Results The consumption of ciprofol and awakening time in group L were less than those in group C(P＜0.05).Compared with group C,MAP at T1 and SpO2 at T1 and T2 were increased in group L(P＜0.05).There was no statistical difference in HR at T0-T4 between groups of L and C(P＞0.05).The incidences of hypotension,hypoxemia and total adverse reactions in group L were lower than those in group C(P＜0.05).Conclusion Intravenous injection of lidocaine can reduce the consumption of ciprofol in painless ultrasonic gastroscopy,increase the stability of perioperative circulation and respiration,and reduce the incidence of adverse reactions.
