Prophylactic use of pregabalin for prevention of succinylcholine-induced fasciculation and myalgia: a randomized, double-blinded, placebo-controlled study
Brazilian Journal of Anesthesiology
Succinylcholine is commonly used to achieve profound neuromuscular blockade of rapid onset and short duration. Objective: The present study compared the efficacy of pregabalin for prevention of succinylcholine-induced fasciculation and myalgia. Design: Prospective, randomized, placebo controlled, double blinded study. Materials and methods: Patients of both genders undergoing elective spine surgery were randomly assigned to two groups. Patients in Group P (pregabalin group) received 150 mg of
... egabalin orally 1 h prior to induction of anesthesia with sips of water and patients in Group C (control group) received placebo. Anesthesia was induced with fentanyl 1.5 mcg/kg, propofol 1.5---2.0 mg/kg followed by succinylcholine 1.5 mg/kg. The intensity of fasciculations was assessed by an observer blinded to the group allotment of the patient on a 4-point scale. A blinded observer recorded postoperative myalgia grade after 24 h of surgery. Patients were provided patient-controlled analgesia with fentanyl for postoperative pain relief. Results: Demographic data of both groups were comparable (p > 0.05). The incidence of muscle fasciculation's was not significant between two groups (p = 0.707), while more patients in group C had moderate to severe fasciculation's compared to group P (p = 0.028). The incidence and severity of myalgia were significantly lower in group P (p < 0.05). Conclusion: Pregabalin 150 mg prevents succinylcholine-induced fasciculations and myalgia and also decreases the fentanyl consumption in elective sine surgery.
