RESUMO
The Women In Cardiothoracic Anesthesiology (WICTA), a special interest group of the Society of Cardiovascular Anesthesiologists, has been highly successful in mobilizing WICTA, a historically underrepresented and marginalized group in the subspecialty, and in supporting real and meaningful change in the professional community. The experience of WICTA as a professional affinity group in impacting a professional organization to diversify, evolve, and become more responsive to a wider professional audience has important lessons for other professional organizations. This article discusses the recent history of affinity organizations in anesthesiology, the benefits they offer professional organizations, and the strategies that have been used to effectively motivate change in professional communities. These strategies include engaging a strong advisory board, identifying the need of constituents, creating additional opportunities for networking and membership, addressing gaps in professional development, and aligning goals with those of the larger national organization. WICTA is just one example of the potential opportunities that affinity groups offer to professional societies and organizations for expanding their reach, enhancing their impact on physicians in their target audience, and achieving organizational missions.

BACKGROUND: Fibrinogen thromboelastometry (FIBTEM) test is clinically used for rotational thromboelastometry as a surrogate measure of fibrinogen. Elevated fibrinogen might confer protection against bleeding after major surgery. This single-center study was conducted to assess any relationship between baseline FIBTEM value and exposure to allogeneic transfusion in patients undergoing coronary artery bypass grafting (CABG). STUDY DESIGN AND METHODS: Data were obtained retrospectively from local FIBTEM data and the Society of Thoracic Surgeons (STS) Adult Cardiac Surgery Database between 2016 and 2019. Preoperative FIBTEM 10-min amplitude (A10) was categorized as low (≤ 18 mm), intermediate (19-23 mm), or high (≥24 mm). The primary outcome was any transfusion during the hospitalization, including red blood cells (RBCs), platelets, plasma, and cryoprecipitate. A multivariable regression model was used to adjust for confounders and calculate an odds ratio (OR) for any transfusion. RESULTS: The high FIBTEM group included more female and African-American patients, as well as urgent surgery. The STS predicted risks of morbidity and mortality were greater, and anemia was most prevalent with high FIBTEM. Unadjusted blood transfusion rates were increased with high FIBTEM due to RBC transfusion, but non-RBC transfusion was highest with low FIBTEM. After adjustments, a lower OR for transfusion was associated with high FIBTEM (0.426; 95% confidence interval, 0.199-0.914) compared to low FIBTEM. CONCLUSION: The high FIBTEM group frequently presented with anemia and comorbidities, and received more RBCs but not non-RBC products. Postoperative blood loss was less with high FIBTEM, and after adjustments, it conferred protection against any transfusion.

Since the first endovascular aortic repair in 1990, endovascular devices and the indications for their use have significantly grown. Considerable progress has been made in endovascular devices and techniques, such that endovascular repair is now considered first-line treatment for patients with descending aortic disease. However, for patients with ascending aortic disease, open surgical repair with cardiopulmonary bypass and hypothermic cardiac arrest was the only option until recently. Although the outcomes for open surgical repair of the ascending aorta have improved over the years, approximately 30% of patients with an emergent surgical indication, such as type A aortic dissection, are considered to be too high risk for open repair. For these patients, endovascular repair of the ascending aorta offers a life-saving procedure. The ascending aorta is regarded as the final frontier for endovascular therapy. Endovascular repair of it has posed a formidable challenge thus far, due to its unique anatomy, hemodynamic forces, and lack of an appropriate stent-graft designed specifically for the ascending aorta. Although currently there are no comprehensive data from randomized clinical trials, there are several case series and case reports that have shown favorable outcomes. Improvements in available devices soon will drive an exponential increase in the number of patients undergoing endovascular ascending aortic repair. In this review, the authors discuss multiple aspects of endovascular ascending aortic repair including the unique surgical and anesthetic considerations, the devices used, and the available outcomes data, and future directions are also explored.

OBJECTIVE: To explore how cytochalasin D (CyD) affects clot initiation and to compare clotting times (CTs) of EXTEM and FIBTEM on rotational thromboelastometry in cardiac surgical patients undergoing cardiopulmonary bypass (CPB). DESIGN: Retrospective cohort study with translational in vitro coagulation experiments. SETTING: Single-center, tertiary, academic medical center. PARTICIPANTS: Patients who underwent cardiac surgery with CPB between November 2015 and August 2017. INTERVENTION: None. MEASUREMENTS AND MAIN RESULTS: The study's primary measurements were CTEXTEM and CTFIBTEM before and after CPB. Additionally, the authors performed translational in vitro coagulation experiments using commercial plasma. In these experiments, the impact of CyD on in vitro thrombin generation (TG) was assessed using 10 platelet-rich plasma (PRP) samples and calibrated automated thrombogram. The impact of CyD on ROTEM-CT also was evaluated in vitro using the same 10 PRP samples. One hundred fifty-three patients had clinical CTEXTEM and CTFIBTEM measurements. CTFIBTEM was shorter than CTEXTEM before and after CPB by 6.8% (95% confidence interval [CI], 5.5-8.1) and 8.9% (95% CI, 4.7-13.0), respectively. These results correlated with in vitro experiments, where TG lag time was shortened by CyD and CTFIBTEM was shorter than CTEXTEM. CONCLUSION: CyD shortens the onset of TG and clot formation, resulting in shorter CTFIBTEM than CTEXTEM. The authors' data suggest that CTEXTEM and CTFIBTEM are not interchangeable. Additional clinical studies are warranted to assess if CTFIBTEM can be used to optimize the indication for plasma transfusion.

OBJECTIVE: To determine the incidence of intra-abdominal hypertension (IAH) in adult cardiac surgery patients and its association with postoperative kidney dysfunction. DESIGN: Prospective cohort study. SETTING: Single tertiary-care university hospital. PARTICIPANTS: Forty-two adult patients having cardiac surgery with cardiopulmonary bypass. INTERVENTIONS: Intra-abdominal pressure (IAP) was measured preoperatively, immediately after surgery, and at the following time points after surgery: 3 hours, 6 hours, 12 hours, and 24 hours. Urine neutrophil gelatinase-associated lipocalin (NGAL) levels were measured as a marker of kidney dysfunction at the following time points: prior to surgery, immediately after surgery, 4 to 6 hours after surgery, and 16-to-18 hours after surgery. MEASUREMENTS AND MAIN RESULTS: Two hundred fifty-two IAPs were measured, and 90 (35.7%) showed IAH. Thirty-five of 42 patients (83.3%) had IAH at 1 time point or more. Peak urine NGAL levels were lower in patients with normal IAP (mean difference = -130.6 ng/mL [95% CI = -211.2 to -50.1], p = 0.002). There was no difference in postoperative kidney dysfunction by risk, injury, failure, loss of kidney function, and end-stage kidney disease (RIFLE) criteria in patients with normal IAP (mean difference = -31.4% [95% CI = -48.0 to 6.3], p = 0.09). IAH was 100% sensitive for predicting postoperative kidney dysfunction by RIFLE criteria, but had poor specificity (54.8%). CONCLUSIONS: IAH occurs frequently during the perioperative period in cardiac surgery patients and may be associated with postoperative kidney dysfunction.

OBJECTIVES: Diffuse isolated liver metastases are the dominant mode of tumor progression in a number of cancers and present a major treatment challenge for oncologists. An experimental treatment, percutaneous hepatic perfusion (PHP), utilizes partial venovenous cardiopulmonary bypass to allow administration of high-dose chemotherapy directly and solely to the liver with filtration of chemotherapeutic agents from the blood prior to its return to the systemic circulation, thereby minimizing toxic systemic effects. The following case series describes the management of 5 patients with metastatic melanoma undergoing serial PHPs. DESIGN: A single-center experience from a national multi-center random-assignment trial comparing PHP to best alternative care (BAC) in patients with diffuse melanoma liver metastases. SETTING: A tertiary care hospital. PARTICIPANTS: Five patients with metastatic melanoma to the liver. INTERVENTION: Five patients underwent a total of fifteen PHPs using a venovenous bypass circuit with hemofiltration, receiving hepatic intra-arterial melphalan, 3 mg/kg of ideal body weight, for 30 minutes with a total of 60 minutes of hemofiltration. MEASUREMENTS AND MAIN RESULTS: Five patients tolerated the procedure well with transient hemodynamic and metabolic changes. CONCLUSIONS: In patients with diffuse isolated liver metastases, PHP is a safe and well-tolerated procedure that can be performed more than once and is associated with marked anti-tumor activity in some patients.

PURPOSE OF REVIEW: To assess the current status and methods of robotic totally endoscopic coronary artery bypass (TECAB) surgery and discuss important anesthetic considerations. RECENT FINDINGS: Technological and surgical advances in robotics have led to the evolution of TECAB surgery from a single-vessel procedure to quadruple-vessel bypass. TECAB is now a reproducible technique, with a low incidence of mortality and morbidity and superior quality of life. Although early cohorts of patients are still being observed for long-term outcomes, initial and midterm outcomes are comparable to those of conventional coronary artery bypass. TECAB is also associated with specific challenges for the anesthesiologist. SUMMARY: TECAB surgery is a feasible alternative to open coronary artery bypass surgery in selected patient populations. Appropriate patient selection, team training, and stepwise application of the procedure are crucial. TECAB is associated with a unique set of challenges, requiring a skilled operative team. As robotic technology and surgical expertise evolve, this technology will find wider application in an increasing high-risk patient population that will require the support of a skilled anesthesiology team.

Over the last decade, TECAB has matured into a reproducible technique associated with low incidence of both mortality and morbidity, as well as superior quality of life, when compared with open CABG surgery. However, TECAB also is associated with important and specific challenges for the anesthesiology team, particularly with regard to the physiologic stresses of OLV, placement of special catheters, and induced capnothorax. As the technology supporting robotic surgery evolves and familiarity with, and confidence in, TECAB increases, the authors anticipate increasingly widespread use of these procedures in an increasingly fragile and problematic patient population who will require the support of a skilled and vigilant anesthesiology team.

We describe a case of a 58-year-old man presenting to the interventional radiology (IR) suite for inferior vena cava (IVC) filter retrieval and potential intravascular iliocaval stent reconstruction in the setting of anticoagulation and uncontrolled hypertension. This patient had recently undergone iliocaval thrombectomy with IVC venoplasty four weeks prior to presentation. Induction of anesthesia and endotracheal intubation occurred without complication. The patient received two large-bore intravenous (IV) catheters and a radial artery catheter for hemodynamic monitoring. Blood was cross-matched and kept in the IR suite, anticipating bleeding from a potential injury to the IVC during filter retrieval. Fortunately, the thrombosed filter was removed without complication. This case illustrates the importance of in-depth anesthetic planning for so-called "benign" surgical procedures and highlights the challenges faced in non-operating room locations for anesthesiologists.
RESUMO
Pain continues to be a well-known complication of cardiac surgery in the postoperative period and intravenous opioid analgesia has traditionally been employed to manage cardiac surgical pain. However, both components have contributed to a multitude of undesirable adverse effects which can further exacerbate delays in recovery. Often overlooked in the analgesic plan, chest tube pain contributes significantly to the overall postoperative pain from cardiac surgery. Novel regional anesthetic blocks have shown great promise as analgesic adjuncts for cardiothoracic anesthesia but preliminary investigations focus primarily on management of sternotomy pain. Reduction of chest tube pain should be considered while implementing regional blocks to control surgical pain. This study presents a case where the rectus sheath block minimized chest tube pain after aortic valve replacement in conjunction with intercostal nerve blocks and a multimodal analgesic plan.
RESUMO
Robotic technology enables "port only" totally endoscopic coronary artery bypass grafting (TECAB). During early procedure development only single bypass grafts were feasible. Because current referral practice for coronary bypass surgery mostly includes multivessel disease, performance of multiple endoscopic bypass grafts is desirable. We report a case in which a patient received a right internal mammary artery bypass graft to the left anterior descending artery and a left internal mammary artery jump graft to 2 obtuse marginal branches. The procedure was performed through 5 ports on the arrested heart using the daVinci S robotic surgical system. This is the first reported triple bypass grafting procedure using an arrested heart approach.

Postpneumonectomy syndrome can have a significant clinical impact on a patient. It presents as progressive dyspnoea due to compression of the contralateral bronchus and/or pulmonary veins. Herein, we present a patient who over a 2-year period developed progressive dyspnoea on exertion and eventually also at rest, due to compression of her left mainstem bronchus and her left inferior pulmonary vein. Surgical correction with implantable adjustable saline implants was undertaken to ameliorate her symptoms. Concurrent use of intraoperative transoesophageal echocardiography permitted real-time adjustment of the implants. This allowed objective measurement and demonstration of normalization of pulmonary vein velocity, which resulted in complete symptom resolution.

Development of robotic technology has enabled totally endoscopic coronary artery bypass grafting (TECAB) procedures. With complete preservation of sternal and thoracic stability, this operation would be an interesting option for obese patients, who are known to be at higher risk for deep sternal wound infection. We describe a case of successful totally endoscopic left internal mammary artery to left anterior descending artery bypass grafting using the da Vinci telemanipulation system in a patient who was morbidly obese. The patient underwent a so called staged hybrid coronary intervention with percutaneous angioplasty and placement of a stent to the right coronary artery.
