  • Title: Effectiveness of atracurium in preventing succinylcholine myalgia.
    Author: Marr AT, Sosis M.
    Journal: AANA J; 1989 Apr; 57(2):128-30. PubMed ID: 2735177.
    Abstract:
    A comparison was made of the incidence of postoperative myalgia (POM) and fasciculations when atracurium (ATR) or d-Tubocurarine (DTC) was given prior to succinylcholine (SDC) for facilitation of tracheal intubation. The subjects were 44 ASA physical status I or II outpatient females undergoing laparoscopy. They were assigned to one of three groups: Group 1 received 0.025 mg/kg ATR; Group 2 received 0.05 mg/kg DTC, and Group 3 received saline (NS). Thiopental was administered one minute and 45 seconds after pretreatment. Three minutes after pretreatment, SDC 1.5 mg/kg was given, and fasciculations were recorded on a scale of 0-3. The patients were questioned one and three days postoperatively about POM and their responses recorded using a scale of 0-3. Fasciculations occurred in 79% of patients given saline, in 46% of those receiving ATR and in 12% of those given DTC. Eighty-five percent of ATR patients were free of POM on postoperative day one. The corresponding figures for DTC and NS were 59% and 43%, respectively. The difference between ATR and NS achieved statistical significance, leading to the conclusion that DTC is a better defasciculant than ATR. DTC was, however, not significantly better than NS in the prevention of POM. Findings suggest that ATR may be the drug of choice for the prevention of POM.
