Background: Tracheal tube (TT), ProsealTM laryngeal mask airway (LMA) and laryngeal tube (LT) were used for general anesthesia. We compared the degree of postoperative sore throat after use of TT, LMA and LT in anesthesized patients.
Methods: Sixty-five patients undergoing surgery were randomized into 3 groups; Group A, B, C. TT, LMA and LT were inserted in group A, B and C, respectively. Fibroptic score was checked by use bronchoscope in group B and C. Using visual analog sclale and 3-point score, degrees of postoperative sore throat were examined.
Results: The degree of postoperative sore throat of LMA was less than TT and LT. LMA showed a better view of the larynx with a fiberoptic laryngoscope. After use of LT and TT, there was not statistically different about postoperative sore throat.
Conclusions: The degree and frequency of postoperative sore throat in ProsealTM LMA were statistically significant less than TT and LT group.
