Anesthetic Considerations for Minimally Invasive, Off-Pump, HeartMate III Implantation.

OBJECTIVE: The authors developed and utilized an anesthetic protocol for the management of an off-pump approach for minimally invasive Heartmate III (HM3) implantation. Their goal was to determine if this method was safe and feasible for patients with in-situ mechanical support. DESIGN: The authors performed a retrospective study of consecutive patients undergoing off-pump HM3 implantation via bilateral minithoracotomies. SETTING: This was a single-institution study at the University of Rochester Medical Center, using the same cardiac anesthesiologist and cardiac surgeon pair. PARTICIPANTS: The authors studied 8 consecutive patients undergoing off-pump HM3 implantation from June 2019 to July 2020. INTERVENTIONS: The authors developed an anesthetic management protocol for off-pump HM3 implantation via bilateral minithoracotomies. MEASUREMENTS AND MAIN RESULTS: As a result, the authors evaluated 88% of men with a mean age of 55.0 ±13.0 years. The median time to extubation was 19.7 hours, with a median intensive care unit length of stay of 6.5 days. Fifty percent of patients required blood transfusions during the first 24 hours after surgery (postoperative), and 63% of patients were free from all postoperative complications. No patients required a right ventricular assist device. The mean hospital stay was 26.3 ± 11.3 days, with an 88% survival to discharge. CONCLUSION: In this single-center study, the authors have described the anesthetic consideration for the implantation of the HM3 left ventricular assist device using a complete sternal-sparing technique without the use of cardiopulmonary bypass. Their results have shown, in a case series of 8 patients, that this is a safe and feasible alternative to traditional techniques in patients with existing mechanical support.

Women Physicians: Gender and the Medical Workplace.

Background: Understanding the work habits, attitudes, and experiences of women physicians is critical for optimal patient care. In a gendered work environment, obstacles faced hinder women physicians from contributing to their full ability. This study investigated how women physicians' work habits are viewed, in the context of women's attitudes and experiences. Methods: An analysis of the medical literature (1990-2017) was undertaken. Published studies were located using search engines, article references, consultation with experts, and relevant Mesh terms. Of 1185 listings, 354 studies were evaluated and 44 articles, selected by three reviewers, were analyzed in detail. Results: Four themes emerged-practice styles, productivity, prevailing attitudes, and the workplace environment. Comparing women physicians to male colleagues as a standard for evaluating performance, for example, undervalues distinctive characteristics women bring to medical practice. Productivity models that focus on work hours, procedures, and publications do not encompass the full scope of patient care. Conclusions: Solutions offered mainly have been designed to help women physicians fit into existing workplace environments, but traditionally available "adapt or exit" options in response to challenges faced appear insufficient. A gender equity perspective helps to explain findings and suggests ways to reshape the health care workplace to better understand, utilize, and retain women physicians.

Aversion for Avulsion: A Case of Delayed Diagnosis of Traumatic Tricuspid Rupture.

Tricuspid rupture secondary to blunt force trauma is a rare diagnosis. However, the incidence of this injury is rising due to the improved initial treatment of complex trauma patients as well as enhanced early detection methods through the use of cardiac ultrasound. We report the case of an otherwise healthy 42 year old male who sustained significant blunt force trauma after a single motor vehicle accident. The diagnosis of traumatic papillary rupture and disruption of the valve apparatus was made on the day of admission after perioperative hemodynamic compromise and the use of intraoperative transesophageal echocardiography. However, treatment was delayed due to concerns of systemic anticoagulation leading to his eventual demise.

Modules for the Technical Skills Section of the OSCE Component of the American Board of Anesthesiology APPLIED Examination.

Introduction: To assess communication and professionalism, as well as technical skills related to patient care, the American Board of Anesthesiology (ABA) has begun administering an Objective Structured Clinical Examination (OSCE) portion of the APPLIED Examination in addition to the Standard Oral Examination component. Methods: We created video modules and a curriculum for anesthesiology resident OSCE preparation for the Interpretation of Monitors and Interpretation of Echocardiography components. The modules can be used individually by trainees or included as part of an OSCE workshop led by faculty educators with seven individual stations matching the content of the actual ABA examination. These modules are recommended for all levels of anesthesiology trainees so that they can gain exposure to the format and the fast pace of the examination. Results: Sixty-six junior and senior anesthesiology residents, fellows, and junior faculty successfully participated in these modules. Seventy-three percent of the participants agreed that after completing these modules, they now had a good understanding of the Interpretation of Monitors and Interpretation of Echocardiography technical skills stations. More than 90% of participants reported that the modules were useful, and more than 70% reported that they now felt prepared for these stations of the OSCE. Discussion: Developing technical skills stations for deliberate practice and preparation for the ABA OSCE is resource intensive. Finding time and faculty to facilitate OSCE preparation is also challenging. With the video modules and scripts included in this publication, residents can practice independently or as part of larger preparation course.

Calm Before the Storm: An Uncomplicated Epicardial Lead Extraction Resulting in DIC and Patient Demise.

A previously stable 77-year-old man with significant cardiac history underwent an uneventful extraction of a Citrobacter-infected and eroded pacemaker lead. His postoperative course was acutely complicated by respiratory failure and quickly progressed into disseminated intravascular coagulation, acute renal failure, shock liver, and ventricular tachycardic arrest. I believe that this is the first case report of such a drastic turn of events after a routine pacemaker lead extraction.

Anesthetic issues for robotic cardiac surgery.

As innovative technology continues to be developed and is implemented into the realm of cardiac surgery, surgical teams, cardiothoracic anesthesiologists, and health centers are constantly looking for methods to improve patient outcomes and satisfaction. One of the more recent developments in cardiac surgical practice is minimally invasive robotic surgery. Its use has been documented in numerous publications, and its use has proliferated significantly over the past 15 years. The anesthesiology team must continue to develop and perfect special techniques to manage these patients perioperatively including lung isolation techniques and transesophageal echocardiography (TEE). This review article of recent scientific data and personal experience serves to explain some of the challenges, which the anesthetic team must manage, including patient and procedural factors, complications from one-lung ventilation (OLV) including hypoxia and hypercapnia, capnothorax, percutaneous cannulation for cardiopulmonary bypass, TEE guidance, as well as methods of intraoperative monitoring and analgesia. As existing minimally invasive techniques are perfected, and newer innovations are demonstrated, it is imperative that the cardiothoracic anesthesiologist must improve and maintain skills to guide these patients safely through the robotic procedure.

Pulmonary function testing.

PURPOSE OF REVIEW: To review the recent literature related to pulmonary function testing and how it relates to the preoperative evaluation. RECENT FINDINGS: There is increased interest in the field of pulmonary arterial hypertension. It is important to determine the clinical implications of this disease and determine whether preoperative therapy is indeed effective. Also, there is a need for the development of new noninvasive diagnostic techniques to identify patients at risk of pulmonary arterial hypertension. SUMMARY: Pulmonary function testing can be used to quantify lung function, confirm an individual's functional status, evaluate regimen effectiveness, and determine disability. They may be essential in all candidates for lung resection. However, there are limits in the current testing of pulmonary function. There is new evidence that exercise testing may provide better diagnostic and prognostic information about patients with cardiovascular and pulmonary disease.

Preoperative evaluation for thoracic surgery.

The goal of the preoperative evaluation for thoracic surgery is to assess and implement measures to decrease perioperative complications and prepare high-risk patients for surgery. Major respiratory complications, such as atelectasis, pneumonia, and respiratory failure, occur in 15% to 20% of patients and account for most of the 3% to 4% mortality rate. Development of pulmonary complications has been associated with higher postoperative mortality rates. Strategies aimed at preventing postoperative difficulties have the potential to reduce morbidity and mortality, decrease hospital stay, and improve resource use. One lung ventilation leads to a significant derangement of gas exchange, and hypoxemia can develop due to increased intrapulmonary shunting. Recent advances in anesthetic management, monitoring devices, improved lung isolation techniques, and improved critical care management have increased the number of patients who were previously considered inoperable. In addition, there is a growing tendency to offer surgery to patients with significant lung function impairment; hence a higher incidence of intraoperative gas-exchange abnormalities can be expected. The anesthesiologist must also consider the risks of denying or postponing a potentially curative operation in patients with lung cancer. Detailed consideration of the information provided by preoperative testing is essential to successful outcomes following thoracic surgery.
