ReviewScreening Modalities for Coronary Artery Disease in Liver Transplant Candidates: A Review of the Literature.
Patients with cirrhosis undergoing liver transplant (LT) are at high risk of postoperative cardiopulmonary complications. It is known that patients with coronary artery disease (CAD) have greater rates of post-LT morbidity and mortality than patients without CAD. Thus, identifying significant CAD in LT candidates is of the utmost importance to optimize survival posttransplant. ⋯ Traditional exercise and many pharmacologic stress tests are impractical and inaccurate in patients with cirrhosis due to their unique physiology. The purpose of this review is to describe different screening modalities for CAD among LT candidates. The background, diagnostic accuracy, and limitations of each screening modality are described to achieve this goal.

Randomized Controlled TrialContinuous Noninvasive Blood Pressure Measurement With "ClearSight" Compared to Standard Intermittent Blood Pressure Measurement in Patients With Peripheral Arterial Disease. Are Potential Differences Influenced by Phenylephrine or Dobutamine?
To investigate the agreement between continuous noninvasive blood pressure measurement with the ClearSight system (cNIBP-CS) and standard intermittent noninvasive blood pressure measurement (iNIBP) in patients with peripheral arterial disease (PAD). Additionally, the influence of vasoactive medication on potential measurement differences was assessed. ⋯ In this study, in patients with PAD, cNIBP-CS showed an underestimation of blood pressure compared to iNIBP in phenylephrine- and dobutamine-treated patients. Compared to previous studies, a larger bias and wider 95% LOA were found.

Randomized Controlled TrialCognitive Deficits in Executive and Language Functions Predict Postoperative Delirium.
Postoperative delirium (POD) remains the most common complication in older adults, with cognitive impairment being the main risk factor. Patients with mild cognitive impairment, in particular, have much to lose from delirium; despite this, their cognitive impairment might be clinically overlooked. Understanding which cognitive domains are particularly predictive in this regard may improve the sensitivity of preoperative testing and allow for a more targeted application of resource-intensive measures to prevent delirium in the perioperative period. The authors conducted this study with the aim of identifying the most indicative cognitive domains. ⋯ Impairment in the cognitive domains of executive function and language skills associated with memory, inhibition, and access speed seem to be particularly associated with the development of delirium after surgery in adults ≥65 years of age without apparent preoperative neurocognitive impairment.

Role of Cardiac Anesthesiologists in Intraoperative Enhanced Recovery After Cardiac Surgery (ERACS) Protocol: A Retrospective Single-Center Study Analyzing Preliminary Results of a Yearlong ERACS Protocol Implementation.
Enhanced recovery after cardiac surgery (ERACS) has been gaining rapid acceptance after multiple studies have demonstrated promising results in improved outcomes of enhanced recovery after surgery in other surgical fields (eg, colorectal, orthopedic, thoracic, etc). Cardiac surgery has several unique challenges, including sternotomy, cardiopulmonary bypass and associated coagulopathy, blood transfusion, and postoperative intensive care requirement. Nonetheless, selective cardiac surgical patients can still benefit from ERACS. Guidelines for perioperative care in cardiac surgery, previously published by the ERACS Society, are weighted heavily in preoperative and postoperative management without much focus on intraoperative care provided by anesthesiologists. To address this gap and to explore anesthesiology's contribution in achieving ERACS, the study authors' cardiac anesthesiology division, in collaboration with cardiac surgery, introduced the ERACS protocol in their institution in February 2020. ⋯ The ERACS is achievable after the careful implementation of a series of measures. It does not signify only fast-track extubation and opioid-sparing analgesia, and must be implemented in the entire perioperative period beginning from preoperative clinic to postoperative rehabilitation. Cardiac anesthesiologists play a vital role in execution of intraoperative ERACS measures. Both providers and patients themselves are key stakeholders. A larger randomized prospective trial is warranted to solidify the inference.

A Modified 4Ts Score for Heparin-Induced Thrombocytopenia in the Mechanical Circulatory Support Population.
To identify risk factors and develop a pretest scoring system to differentiate patients with heparin-induced thrombocytopenia (HIT) in the mechanical circulatory support (MCS) population. The authors present a modified "4TMCS" scoring system, which considers the "type of mechanical circulatory support" that may help identify patients at risk for developing postoperative HIT. ⋯ Heparin-induced thrombocytopenia is associated with worse outcomes and increased morbidity and mortality in the MCS population. Awareness of patient risk factors and the application of a modified 4TMCS probability score may allow for more accurate screening and treatment of HIT in the MCS population.
