Background: Postoperative sore throat after minor pediatric surgery although uncommon and the symptoms are mild, the incidence may be affected by several factors. This study was designed to compare the frequency and severity of post operative sore throat in children undergoing elective surgery following the use of proseal LMA (PLMA) compared to classic LMA (cLMA).
Methods: Two hundred children, 6 to 12 years old undergoing general anesthesia were selected and randomly divided into two groups which involved the use of the PLMA and the cLMA respectively. Induction of anesthesia was done with fentanyl 1 mcg/kg and propofol 2-3 mg/kg or sevoflurane 8% depending on the preference of the clinicians. Postoperatively, airway devices were removed when patients were fully awake and given supplemental oxygen via face mask.
Results: At 6 hours postoperatively, the incidence of sore throat was lower in the Proseal LMA group (p<0.001).
Conclusion: The incidence of sorethroat was lower in the Proseal LMA group compared to Classic LMA at 6 hours postoperatively.
