Clinical Approach to Massive Hemoptysis: Perioperative Focus on Causes and Management.

Massive hemoptysis is a time critical airway emergency in the perioperative setting, with an associated mortality exceeding 50%. Causes of hemoptysis in the perioperative setting include procedural complication, coagulopathy, malignancy, chronic lung disease, infection, left-sided cardiac disease, pulmonary vascular disease and autoimmune disease. A rapid and coordinated multidisciplinary response is required to secure the airway, isolate the lung, ensure adequate oxygenation and ventilation, identify the underlying cause and initiate specific systemic, bronchoscopic, endovascular, or surgical treatment.

Adverse Clinical Effects Associated With Non-catecholamine Pharmacologic Agents for Treatment of Vasoplegic Syndrome in Adult Cardiac Surgery.

Vasoplegic syndrome is a relatively common complication that can happen during and after major adult cardiac surgery. It is associated with a higher rate of complications, including postoperative renal failure, longer duration of mechanical ventilation, and intensive care unit stay, as well as increased mortality. The underlying pathophysiology of vasoplegic syndrome is that of profound vascular hyporesponsiveness, and involves a complex interplay among inflammatory cytokines, cellular surface receptors, and nitric oxide (NO) production.

Beyond the self: a novel framework to enhance non-technical team skills for anesthesiologists.

Human factors and non-technical skills (NTS) have been identified as essential contributors to both the propagation and prevention of medical errors in the operating room. Despite extensive study and interventions to nurture and enhance NTS in anesthesiologists, gaps to effective team practice and patient safety remain. Furthermore, the link between added NTS training and clinically significant improved outcomes has not yet been demonstrated.

Perioperative Glycemic Management in Cardiac Surgery: A Narrative Review.

Diabetes and hyperglycemic events in cardiac surgical patients are associated with postoperative morbidity and mortality. The causes of dysglycemia, the abnormal fluctuations in blood glucose concentrations, in the perioperative period include surgical stress, surgical techniques, medications administered perioperatively, and patient factors. Both hyperglycemia and hypoglycemia lead to poor outcomes after cardiac surgery.

Anesthesia for Nonintubated Video-Assisted Thoracoscopic Surgery.

With the growing adoption of Enhanced Recovery After Surgery protocols across all surgical groups, including thoracic surgery, coupled with improved video-assisted thoracoscopic surgery (VATS) equipment and techniques, nonintubated thoracoscopic surgery has gained significant popularity in recent years. Avoiding tracheal intubation with an endotracheal or double-lumen tube and general anesthesia may reduce or eliminate the risks associated with traditional mechanical ventilation, one-lung ventilation, and general anesthesia. Studies have shown a trend toward better preservation of postoperative respiratory function and improved postoperative lengths of hospital stay, morbidity, and mortality; however, these have not been conclusively proven.

Review of Postoperative Care for Heart Transplant Recipients.

The early postoperative management strategies after heart transplantation include optimizing the function of the denervated heart, correcting the causes of hemodynamic instability, and initiating and maintaining immunosuppressive therapy, allograft rejection surveillance, and prophylaxis against infections caused by immunosuppression. The course of postoperative support is influenced by the quality of allograft myocardial protection prior to implantation and reperfusion, donor-recipient heart size matching, surgical technique of orthotopic heart transplantation, and patient factors (eg, preoperative condition, immunologic compatibility, postoperative vasomotor tone, severity and reversibility of pulmonary vascular hypertension, pulmonary function, mediastinal blood loss, and end-organ perfusion). This review provides an overview of the early postoperative care of recipients and includes a brief description of the surgical techniques for orthotopic heart transplantation.

Total intravenous anesthesia for liver resections: anesthetic implications and safety.

Inhalational anesthetics have been the default agents for general anesthesia maintenance for several decades. However, with advances in total intravenous anesthesia (TIVA) and a growing body of evidence on the potential benefits of TIVA, anesthesiologists need to question this paradigm. Some of the benefits of propofol-based TIVA, such as its antiemetic properties and patients' smooth emergence, are widely acknowledged.

Infection Control for Perioperative Ultrasonography and Echocardiography.

Ultrasound technology has revolutionized point-of-care diagnostics, decision-making, and the guidance of interventional procedures in Anesthesiology and Perioperative Medicine. Recent literature has highlighted important infection control considerations when performing transesophageal or transthoracic echocardiography, point-of-care ultrasound, and ultrasound-guided procedures. This narrative review focuses on operator precautions and disinfection methods and summarizes key recommendations from the international Echocardiography and Radiology Societies.

Preoperative Evaluation and Care of Heart Transplant Candidates.

Heart transplantation is recommended for patients with advanced heart failure refractory to medical and device therapy, and who do not have absolute contraindications. When patients become eligible for heart transplantation, they undergo comprehensive evaluation and preparation to optimize their posttransplantation outcomes. This review provides an overview of the processes that are employed to enable the candidates to be transplant-ready when donor hearts are available.

Heparin Resistance During Cardiopulmonary Bypass in Adult Cardiac Surgery.

The use of heparin for anticoagulation has changed the face of cardiac surgery by allowing a bloodless and motionless surgical field throughout the introduction of cardiopulmonary bypass (CPB). However, heparin is a drug with complex pharmacologic properties that can cause significant interpatient differences in terms of responsiveness. Heparin resistance during CPB is a weighty issue due to the catastrophic consequences stemming from inadequate anticoagulation, and the treatment of it necessitates a rationalized stepwise approach due to the multifactorial contributions toward this entity.

Pulmonary thromboendarterectomy and pulmonary haemorrhage.

Pulmonary thromboendarterectomy surgery is the recommended treatment for patients with chronic thromboembolic pulmonary hypertension. Massive intraoperative pulmonary haemorrhage with bleeding into the airway is a rare complication, and it typically presents as cardiopulmonary bypass flow is reduced and blood begins to flow through the pulmonary circulation. Immediate management includes maintaining extracorporeal circulation to reduce blood flow through the pulmonary circulation, isolation of the affected lung, while the surgeon identifies and repairs the site of haemorrhage.

Diagnosis of bone cement implantation syndrome using point of care ultrasound examination.

Once regarded as a rare complication, the potentially fatal bone cement implantation syndrome (BCIS) has been increasingly reported. BCIS can present as transient desaturation, hypotension, cardiac dysrhythmias, and cardiovascular collapse. Diagnosis of BCIS is often clinical and confirmed with computed tomography (CT) imaging postoperatively.

Red-Colored Urine in the Cardiac Surgical Patient-Diagnosis, Causes, and Management.

Red-colored urine occurring in the intraoperative and early postoperative periods after cardiac surgery is often a cause for concern. This observation may be a result of hematuria from pathology within the urinary tract, anticoagulant-related nephropathy, drug-induced acute interstitial nephropathy, excretion of heme pigment-containing proteins, such as myoglobin and hemoglobin, and hemolysis occurring during extracorporeal circulation. Within the kidneys, heme-containing compounds result in pigment nephropathy, which is a significant contributory factor to cardiac surgery-associated acute kidney injury.
