Abstract:
Previous research has shown that office‐based laryngoscopic procedures can induce hemodynamic changes, including tachycardia and severe hypertension, calling into question the safety of these procedures. However, comparison between office and operating room (OR) procedures has not been carried out. Therefore, we prospectively measured hemodynamic variables in both settings to compare hemodynamic changes between office and OR procedures. Study Design Prospective cohort study. Setting Single academic center. Subjects and Methods Subjects undergoing office and OR laryngoscopic procedures were prospectively identified, and 92 OR and 70 office subjects were included. Heart rate and blood pressure were measured at established time points before, during, and after the procedures. Descriptive and comparative statistical analyses were conducted. Results Severe hemodynamic events, either tachycardia or severe hypertension (blood pressure 〉 180 mm Hg systolic or 〉 110 mm Hg diastolic), occurred significantly more frequently in OR than office procedures (41% vs 20%; P =. 006). OR severe hemodynamic events occurred more commonly than previously reported rates in the office (41% vs 28%; P =. 012). Regression analyses showed that the odds of having a severe hemodynamic event were 3.66 times higher in OR versus office procedures. Conclusion Severe hemodynamic events are more likely to occur in the OR than in the office during laryngologic procedures. While larger studies will be required to establish rates of dangerous cardiovascular events in laryngoscopic procedures, hemodynamic parameters indicate that office‐based procedures have a safety benefit for procedures that can be conducted in either setting.
