Association Between Single-Injection Regional Analgesia and Postoperative Pain in Cardiac Surgery Patients: A Single-Center Retrospective Cohort Study.

Objectives: Effective pain control after cardiac surgery may facilitate recovery. This study aimed to assess the use and association of ultrasound-guided single-injection chest wall blocks with liposomal bupivacaine on postoperative pain scores and short-term opioid requirements after cardiothoracic surgery at a single institution.

Design: Retrospective cohort study.

Considerations for the use of porcine organ donation models in preclinical organ donor intervention research.

Use of animal models in preclinical transplant research is essential to the optimization of human allografts for clinical transplantation. Animal models of organ donation and preservation help to advance and improve technical elements of solid organ recovery and facilitate research of ischemia-reperfusion injury, organ preservation strategies, and future donor-based interventions. Important considerations include cost, public opinion regarding the conduct of animal research, translational value, and relevance of the animal model for clinical practice.

Cardiac function unchanged following reanimation with normothermic regional perfusion in donation after circulatory death.

Objectives: To determine whether hearts reanimated with normothermic regional perfusion (NRP) have clinically detectable changes in function using echocardiography comparing the prearrest and post-NRP imaging. As heart transplantation from donation after circulatory death (DCD) continues to increase, preliminary results suggest outcomes comparable with donation after brain death. It is unknown whether the obligatory period of warm ischemia experienced during DCD withdrawal process causes immediate changes in cardiac allograft function following in situ reanimation.

Creation of a High-Fidelity, Low-Cost, Intraosseous Line Placement Task Trainer via 3D Printing.

The description of procedural task trainers includes their use as a training tool to hone technical skills through repetition and rehearsal of procedures in a safe environment before ultimately performing the procedure on a patient. Many procedural task trainers available to date suffer from several drawbacks, including unrealistic anatomy and the tendency to develop user-created 'landmarks' after the trainer tissue undergoes repeated manipulations, potentially leading to inappropriate psychomotor skill development. To ameliorate these drawbacks, a process was created to produce a high-fidelity procedural task trainer, created from anatomy obtained from computed tomography (CT) scans, that utilize ubiquitous three-dimensional (3D) printing technology and off-the-shelf commodity supplies.

Infectious Aerosol Capture Mask as Environmental Control to Reduce Spread of Respiratory Viral Particles.

Negative pressure isolation of COVID-19 patients is critical to limiting the nosocomial transmission of SARS-CoV-2; however, airborne isolation rooms are limited. Alternatives to traditional isolation procedures are needed. The evaluation of an Infectious Aerosol Capture Mask (IACM) that is designed to augment the respiratory isolation of COVID-19 patients is described.

Comparison of 3D printed anatomical model qualities in acetabular fracture representation.

Background: Acetabular fractures account for 10% of pelvis injuries, which are especially difficult to treat in developing countries with less access to resources. 3D printing has previously been shown to be a beneficial method of surgical planning, however the steep initial costs associated with purchasing a 3D printer may prevent some facilities form utilizing this technique. The purpose of this study was to develop 3D printed models for acetabular surgery using methodologies of varying cost to determine differences in model accuracy and overall quality.

Thoracoabdominal Normothermic Perfusion in Donation After Circulatory Death.

Donation after circulatory death is emerging as an alternative pathway to donation after brain death to expand the cardiac organ donor pool. We describe the surgical technique and circuit configuration for in-situ organ reperfusion with thoracoabdominal normothermic regional perfusion using portable venoarterial extracorporeal membrane oxygenation.

Successful lung transplantation with graft recovered after thoracoabdominal normothermic perfusion from donor after circulatory death.

Lung transplantation with lungs procured from donors after circulatory death (DCD) has been established as an alternative technique to traditional donation after brain death (DBD) with comparable outcomes. Recently, in situ thoracoabdominal normothermic regional perfusion (TA-NRP) has emerged as a novel technique employed in the procurement of cardiac allografts after circulatory death. TA-NRP, in contrast to ex situ machine perfusion, has the advantage of allowing in situ assessment of donor organs prior to final acceptance.

2020 Clinical Update in Liver Transplantation.

The gold standard treatment of end-stage liver disease continues to be liver transplantation (LT). The challenges of LT require skilled anesthesiologists to anticipate physiologic changes associated with end-stage liver disease and surgical considerations that affect multiple organ systems. While on the waiting list, patients may be placed on new anticoagulation medications that can confound already complex coagulopathy in LT patients.

3D printing of face shields to meet the immediate need for PPE in an anesthesiology department during the COVID-19 pandemic.

Background: Anesthesia providers are at risk for contracting COVID-19 due to close patient contact, especially during shortages of personal protective equipment. We present an easy to follow and detailed protocol for producing 3D printed face shields and an effective decontamination protocol, allowing their reuse.

Methods: The University of Nebraska Medical Center (UNMC) produced face shields using a combination of 3D printing and assembly with commonly available products, and produced a simple decontamination protocol to allow their reuse.

Assessment of Resident Performance During the Cardiac Anesthesia Rotation: Application of the House Officer Clinical Assessment in Cardiac Anesthesiology.

Objective: The assessment of clinical skills was created that evaluates House Officer performance within 13 clinical domains during the Cardiac Anesthesiology rotation to provide an assessment and evaluation process for residents while performing a cardiac anesthetic.

Design: A retrospective evaluation of performance assessments over a 33-month period.

Setting: University hospital-based Accreditation Council for Graduate Medical Education accredited Residency Training program.

2019 Clinical Update in Liver Transplantation.

Liver transplantation continues be the standard for treatment of end-stage liver disease, and even with recent advances in organ preservation, the anesthetic management continues to require understanding of multiple organ systems beyond the liver. Multiple factors contribute to hemodynamic changes after reperfusion of the liver graft that anesthesiologists should be aware of before unclamping. Concomitant renal dysfunction in end-stage liver disease is not uncommon, and preparation for continuous renal replacement therapy may need to be considered in certain cases.

Perioperative Management of Recurrent Fungal Tricuspid Endocarditis in a Young Patient Abusing Intravenous Drugs.

• Symptoms of right-sided endocarditis include fever and respiratory symptoms. • Most cases of right-sided endocarditis resolve with conservative medical treatment. • The mortality of fungal endocarditis is high, and surgical treatment is indicated.

Zero balance ultrafiltration using dialysate during nationwide bicarbonate shortage: a retrospective analysis.

Background: Zero balance ultrafiltration (Z-BUF) utilizing injectable 8.4% sodium bicarbonate is utilized to treat hyperkalemia and metabolic acidosis associated with cardiopulmonary bypass (CPB). The nationwide shortage of injectable 8.

2018 Clinical Update in Liver Transplantation.

Liver transplantation (LT) continues to be the gold standard for treating end-stage liver disease, and challenges that are posed to the anesthesiologist during transplantation are well known. Successful liver transplantation requires knowledge, recognition, and treatment of hemodynamic and metabolic disturbances by the anesthesiologist. End-stage liver disease causes unique derangements to the clotting cascade, increasing risk both for hemorrhagic and thrombotic events.
