Background:
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 150mg of pregabalin orally 1h prior to induction of anesthesia with sips of water and patients in Group C (control group) received placebo. Anesthesia was induced with fentanyl 1.5mcg/kg, propofol 1.5-2.0mg/kg followed by succinylcholine 1.5mg/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 24h 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 150mg prevents succinylcholine-induced fasciculations and myalgia and also decreases the fentanyl consumption in elective sine surgery.
