The Cardiothoracic Anesthesiologist as a Perioperative Consultant—Echocardiography and Beyond

Perioperative Transthoracic Echocardiography Practice By Cardiac Anesthesiologists-Report of a "Start-Up" Experience

OBJECTIVE

In this paper, the authors report their experience of perioperative transthoracic echocardiography (TTE) practice and its impact on perioperative patient management.

DESIGN

Retrospective case series.

SETTING

Single institution, tertiary university hospital.

PARTICIPANTS

A total of 101 adult ASA II-V male and female patients >18 years old who were scheduled for or having surgery were included in this retrospective case series.

INTERVENTIONS

All patients underwent a focused perioperative TTE exam performed by cardiac anesthesiologists with significant TTE experience, and further clinical management was based on echocardiography findings discussed with the anesthesia care team.

MEASUREMENTS

Significant echocardiographic findings and changes in patient management were reported. Step-up management was a new intervention that was executed based on echocardiographic findings (volume infusion, inotropic therapy, cardiology consultation, and other interventions), and step-down management was avoidance of an unnecessary intervention based on echocardiographic findings (proceeding to surgery without cancellation, delay, cardiology consultation, and additional investigations/interventions).

MAIN RESULTS

Fifty-three percent of TTEs were performed in the preoperative setting, 34% were intra-operative, and 13% were postoperative. No significant findings were detected in 38 patients, leading to step-down management in all of them. Among patients with positive findings, left ventricular dysfunction (12.8%), hypovolemia (10.8%), and right ventricular dysfunction (7.9%) were the most common. Step-up therapy included inotropic/vasopressor therapy (24.8%), intensive care admission after surgery for further management (13.8%), volume infusion (12.8%), and other interventions (additional monitoring, surgical delay, cardiology consultation, and modification of surgical technique).

CONCLUSION

Perioperative focused TTE examination is useful in the diagnosis of new cardiac conditions for anesthesia management (intraoperative monitoring and hemodynamic therapy) and postoperative care (intensive care unit admissions). Perioperative TTE performed by anesthesiologists can also help avoid procedural delays and unnecessary consults.

Fifteen Years of Transesophageal Echocardiography in Cardiac Anesthesia in Russia

Transesophageal echocardiography was first introduced in Russia as a component of anesthesiology monitoring in 2003 following its successful implementation in the practice of cardiac anesthesia in the United States and Western Europe. This novel opportunity for perioperative hemodynamic evaluation was enthusiastically adopted at several cardiac surgical clinics despite the presence of critical barriers. The most important of these were the lack of certification programs for anesthesiologists, limited equipment, and a lack of understanding of the responsibility of the anesthesiologist as the coordinator of perioperative therapeutic decisions. Although intraoperative transesophageal echocardiography as a part of the anesthesiology protocol has been introduced in less than 10% of Russian cardiac surgery clinics, a group of interested anesthesiologists has formed over the last 15 years. Both the technical conditions and professional mentality of anesthesiologists need to be changed substantially for successful further development of intraoperative echocardiography. This review aims to highlight the milestones, successes, and challenges in the implementation of intraoperative echocardiography in the practice of cardiac anesthesiology in Russia, which may be interesting to a wide range of cardiac anesthesiologists.
