Myoclonus is a major side-effect following etomidate injection requiring use of medical intervention.
In this double-blinded clinical trial, 50 consecutive patients, randomly received sufentanil 0.2 μg/kg or midazolam 0.015 mg/kg, 90 s before induction of anesthesia with etomidate (0.3 mg/kg). Then, the patients were monitored for any myoclonic movements during anesthesia.
The incidence of myoclonus was 28% in the sufentanil group and 84% in the midazolam group. The frequency and intensity of myoclonus were significantly higher in the midazolam group, compared to the sufentanil group (P < 0.001). Myoclonus duration in the sufentanil and midazolam groups were 5.8 ± 13.2 and 69 ± 47.8 s, respectively (P < 0.0010).
The frequency, intensity and duration of myoclonus in the midazolam group, were significantly more prevalent than the sufentanil group.
肌阵挛是依托咪酯注射后的主要副作用,需要进行医学干预。
在这项双盲临床试验中,50例连续患者在依托咪酯(0.3mg/kg)麻醉诱导前90秒随机接受舒芬太尼0.2μg/kg或咪达唑仑0.015mg/kg。然后,在麻醉期间对患者进行任何肌阵挛运动的监测。
舒芬太尼组肌阵挛发生率为28%,咪达唑仑组为84%。与舒芬太尼组相比,咪达唑仑组肌阵挛的频率和强度显著更高(P<0.001)。舒芬太尼组和咪达唑仑组的肌阵挛持续时间分别为5.8±13.2秒和69±47.8秒(P<0.0010)。
咪达唑仑组肌阵挛的频率、强度和持续时间明显比舒芬太尼组更普遍。
