A Thesis submitted to The University of Arizona College of Medicine - Phoenix in partial fulfillment of the requirements for the Degree of Doctor of Medicine. / Objective: To compare findings of emergency echocardiography (rescue echo) in the intra‐
operative period to findings of rescue echo in the ICU setting.
Design: We queried a database of perioperative echo for all rescue echo studies done over a two year period. We compared the frequency of left ventricular (LV) and right ventricular (RV) systolic dysfunction, LV diastolic dysfunction, LV segmental wall motion abnormalities, and hypovolemia of the intraoperative and ICU studies.
Results: LV and RV systolic dysfunction were more prevalent in ICU rescue echo studies compared to intra‐op rescue studies (22% vs. 10%, and 34% vs. 13%, respectively, p<0.05 for each). LV diastolic dysfunction was more prevalent in ICU rescue echo studies compared to intra‐op rescue studies (60% vs. 48%, p<0.05). Segmental wall motion abnormalities (SWMA) were more prevalent in the ICU compared to intra‐op setting (38% vs. 19%, p<0.05).
Conclusion: In an observational study of real‐world rescue echo, the incidence of LV and RV systolic dysfunction, LV diastolic dysfunction, and LV SWMA were all more common in the ICU compared to the intra‐op studies. This could reflect the differences in patient population, differences in reasons clinicians perform rescue echo in the OR and in the ICU, or the hemodynamic effects of anesthesia.
