After written informed consent is received in pre-op, a sealed and coded envelope with either the zinc lozenge or the placebo lozenge will be given to the patient to be administered orally, with the instruction to dissolve the lozenge by sucking on it 30 minutes prior to surgery. Upon completion of surgery and emergence from general anesthesia, the patient will be extubated and transferred to the post-anesthesia care unit (PACU). Once in the PACU, the patient will be assessed regarding the incidence and severity of POST by the study investigator using a standardized scale. The severity of POST will be graded on a 4-point scale ranging from 0 to 3; 0 being no sore throat, 1 being mild discomfort (complains only upon questioning), 2 being moderate sore throat (complains on his/her own), and 3 being severe sore throat (change in voice, hoarseness, and throat pain). This evaluation will be performed at 30 minutes, 2 hours, 4 hours, and 24 hours post-surgery, with the assessment at 4 hours being the primary outcome of the study.
