Preprocedural Paracetamol Reduces Pain Scores in Patients Undergoing in-Office Laryngeal Procedures.

Abstract

To investigate the utility of preprocedural paracetamol on reducing pain scores post office-based laryngeal procedures. Prospective, controlled before-after comparative study. Controlled prospective before-after study. A retrospective analysis was performed of 100 patients who underwent office-based laryngeal procedures without preprocedural analgesia at our center to establish a control group. Age, sex, procedure type, and amount of substance used were documented as well as postprocedural pain score. Pain scores were recorded every 5 minutes for 30 minutes following office-based laryngeal procedures. A prospective arm of this study was then performed in which every patient undergoing office-based laryngeal procedures at our center between September 2019 and December 2020 was administered 1000 mg of paracetamol prior to their procedure. The postprocedure pain scores of the 2 groups were then compared. A hundred patients were included in the retrospective arm and 75 patients were included in the prospective arm, receiving 1000 mg of paracetamol a median of 45 (interquartile range: 30-53) minutes prior to their procedure. The 2 groups were matched for age, sex, and type of laryngeal procedure. Both nonanalgesia and analgesia groups demonstrated a similar proportion of patients who experienced any pain (47% and 48%, respectively) postprocedurally. The prospective arm of this study however reported a statistically significant reduction in the magnitude of their pain scores at all points postprocedurally (P = .005). Paracetamol preprocedurally reduces the severity of pain in office-based laryngeal procedures and would be a useful consideration for patients who are likely to experience significant postprocedural pain. Level 3.
