Purpose of reviewRecent literature has described the emerging role of anesthesiologists as key members of the lung transplantation team and the impact of anesthetic management on outcomes. This review examines the impact of presenting cause of end-stage lung disease (ESLD) on anesthetic management.Recent findingsThe four primary causes of ESLD are suppurative, obstructive, or restrictive processes, and pulmonary hypertension. Our recent review of perioperative literature revealed new data regarding preoperative risk stratification, intraoperative management, and postoperative use of extracorporeal membrane oxygenation (ECMO) support. Major studies specifically about anesthetic management are lacking; however, the principles studied are readily applicable to the design of a perioperative care plan. The most compelling data have resulted in a revolutionary change in terms of intraoperative support and postoperative planning for pulmonary hypertension patients. Historically treated with cardiopulmonary bypass, significant data have been reported describing the successful use of ECMO both as an intraoperative support with superior outcomes, as well as postoperative support for improved stability during biventricular remodeling post graft implantation.SummaryThe application of these updated findings should assist anesthesiologists as they develop internal protocols and external guidelines to integrate within multidisciplinary teams caring for the lung transplant patient.

Objectives: Awareness of the impact of bedside ultrasound to reduce iatrogenic pneumothoraces while performing bedside pleural procedures has increased but with little understanding in how ultrasound is used for these procedures. Design and Setting: We conducted a retrospective chart review at a tertiary referral center in the United States from January 1, 2014, to March 31, 2017. Our study assessed adverse effect rates between real-time ultrasound-guided and ultrasound-marked thoracenteses and thoracostomy tube placements. Patients: Three-hundred ninety-four ICU patients were included in this study. Measurements and Main Results: There was a significant difference in the rate of adverse effects between real-time ultrasound-guided (0.63% [95% CI, 0.11–3.4%]) and ultrasound-marked (6.89% [95% CI, 4.15–11.24%]; p ≤ 0.01) procedures. More specifically, the rate of pneumothoraces was different between the two procedures (0.63% [95% CI, 0.11–3.4%] vs 4.43% [95% CI, 2.35–8.21%]; p = 0.02). In patients mechanically ventilated, there was a significant difference in overall adverse effect rates between groups of ultrasound use ( p = 0.01). Conclusions: The use of real-time ultrasound guidance was associated with a lower rate of iatrogenic pneumothoraces.

We present the case of a 37 year old male who presented with new onset dyspnea, tachycardia, palpitations, and chest tightness. His initial work up demonstrated a dilated pulmonary artery with reflux of contrast dye in to the IVC. Transthoracic echocardiogram identified a “windsock” appearance indicating Sinus of Valsalva aneurysm (SVA) and severe aortic regurgitation. As a result, the patient was taken for emergent surgery where the windsock tissue was surgically repaired with bovine pericardial patch. This case illuminates the uncommon occurrence of SVA and the ability to recognize these findings on multiple imaging modalities including transthoracic, transesophageal two and three dimensional echocardiography as well as direct surgical field visualization.

Infections caused by the Bartonella species are responsible for the human diseases collectively called ‘bartonellosis’. The clinically important human infections are mostly caused by the three species (eg, B. bacilliformis, B. quintana and B. henselae) of Bartonella out of the many progressively increasing identified species. Bartonella henselae transmitted by the arthropod vector, fleas, after cat bite is responsible for the rare multisystem cat scratch disease in humans. We present an extremely rare case of B. henselae contracted presumably through a red ant bite. The patient had a prolonged hospital stay for persistent encephalopathy due to delay in diagnosis and initiation of antimicrobial therapy. His hospital course was complicated by two episodes of pulseless electrical activity cardiac arrest related to pulmonary embolism. However, he recovered to his baseline status in the hospital with timely administration of systemic anticoagulation and antimicrobials. He was discharged home with no neurological deficits.
