  1. Fisher’s exact test was used to calculate the incidence and severity
  2. *MF Midazolam with Fentanyl, M Midazolam
  3. The occurrence and severity of myoclonus were graded in none, mild, moderate, and severe. A short movement of a body segment like finger or shoulder (mild myoclonus), movement of two different muscles or muscle groups of the body, e.g., face and leg (moderate myoclonus) and intense clonic movement in two or more muscle groups like fast abduction of a limb (severe myoclonus)
