OBJECTIVE: To assess whether the different fiberoptic bronchoscopy (FOB) grades of laryngeal mask airway (LMA) Supreme™ affects pharyngolaryngeal morbidity (PLM, including sore throat, dysphonia, pharyngoxerosis, and dysphagia) after general anesthesia.
METHODS: A total of 235 adult patients scheduled for elective laser lithotripsy undergoing general anesthesia with the placement of LMA Supreme™ were enrolled. The position of LMA Supreme™ was assessed by FOB and categorized into five grades. Meanwhile, patients were divided into four groups (grades A-D); none was assessed as grade E. We collected blinded data on PLM at 2 (H+2), 6 (H+6), and 24 hours (H+24) postoperatively. The incidence and severity of PLM as the primary outcome and incidence of PLM at three time points as a secondary outcome were compared.
RESULTS: The incidence of PLM was higher at 2 and 6 hours than at 24 hours; however, no significant difference was found between the incidence of PLM in the FOB groups. Furthermore, the severity of sore throat and dysphonia between groups were obviously differed at H+6 and H+24, but similar at H+2. The severity of postoperative pharyngoxerosis and dysphagia were similar between groups at three time points.
CONCLUSIONS: A positive association was found between the severity of postoperative sore throat and dysphonia and FOB grade after LMA Supreme™ placement. PLM secondary to placement of the LMA Supreme™ was short lasting.
