    Importance of Transesophageal Echocardiography for Stroke Prevention in Patients Undergoing Coronary Artery Bypass Graft Surgery - Case Report
    (2022-09-17) Moseman, Anthony; Raniwsky, Alec; Carmony, Megan
    Background: Transesophageal echocardiography (TEE) has become routine during cardiovascular and thoracic anesthesia. It plays a key role in surgical planning and provides vital hemodynamic information intraoperatively. Case Presentation: A 61-year-old female undergoing coronary artery bypass graft surgery, in which an intraoperative TEE was performed. Subsequently, a left atrial appendage thrombus was discovered. The case was postponed allowing for adequate anticoagulation. Successful CABG was performed after outpatient TEE determined the resolution of the left atrial appendage thrombus. Conclusions: The use of TEE intraoperatively stresses the importance of stroke prevention in patients undergoing high-risk surgeries.

    Risk of acquired methemoglobinemia with different topical anesthetics during endoscopic procedures
    (Dove Press, 2011) Vallurupalli, Srikanth; Manchanda, Shalini; Medicine, School of Medicine
    Introduction: Methemoglobinemia is a recognized complication of the use of topical anesthetic sprays. The true scope of the problem or the risk with different topical anesthetic sprays and endoscopic procedures is unknown. Methods: We retrospectively identified all cases of methemoglobinemia that occurred in a university affiliated community hospital from 2001 to 2007. Results: Eleven cases of methemoglobinemia were identified over the 6-year period. Nine (82%) occurred with use of benzocaine spray during transesophageal echocardiography (TEE). Patients who developed methemoglobinemia secondary to the topical anesthetic spray compared to other causes were more likely to be older, have lower mean hemoglobin levels (10.5 ± 0.5 g/dL vs 11.3 ± 0.0 g/dL), and a higher mean methemoglobin concentration at diagnosis (40.8% ± 5.2% vs 24% ± 10%). However, only age reached statistical significance (P = 0.004). Conclusion: In a university-affiliated community hospital, topical anesthetic sprays account for most of the burden of methemoglobinemia. Benzocaine use in the context of TEE caused more methemoglobinemia compared to lidocaine and other endoscopic procedures. This observation supports previous data and findings deserve further study.
