The aim of the survey was to understand the contemporary thoracic anesthesia practice in India. ⋯ Despite the challenges offered by limited resources, the practice of thoracic anesthesia in India is at par with the standards followed across the world.

Accuracy and Trending Ability of Cardiac Index Measured by the CNAP System in Patients Undergoing Abdominal Aortic Aneurysm Surgery.
The CNAP system is a noninvasive monitor that provides a continuous arterial pressure waveform using an inflatable finger cuff. The authors hypothesized that dramatic changes in systemic vascular resistance index during abdominal aortic aneurysm (AAA) surgery might affect the accuracy of noninvasive pulse contour monitors. The aim of this study was to evaluate the accuracy and trending ability of cardiac index derived by the CNAP system (CICN) in patients undergoing AAA surgery. ⋯ CICN is not interchangeable with CI3D in patients undergoing AAA surgery. The trending ability for CICN at aortic clamping and unclamping was below the acceptable limit. These inaccuracies might be secondary to the high systemic vascular resistance index during AAA surgery.

Cardiac Output Measurement With Echocardiography and Pressure Recording Analytical Method in Pediatric Patients Admitted to the Cardiac Intensive Care Unit: A Retrospective Assessment of Bias Between the Two Methods.
This study aimed to compare, in a cohort of critically ill children with biventricular anatomy and no cardiovascular shunt, cardiac output (CO) and cardiac index (CI) assessed by echocardiography and a continuous pulse-contour method, MostCareUP, to measure the differences between these techniques (biasCO and biasCI), and their association with clinical variables. ⋯ Children with extreme low or high weights, those who are extubated, and those with a femoral cannula carry the highest bias. When younger patients are considered, CI should be evaluated instead of CO, because biases are better highlighted by indexing data on body surface area. In children, both echocardiography and MostCareUP may be responsible of inaccurate CO/CI assessment.

Case ReportsPeripheral Cardiopulmonary Bypass in Two Patients With Symptomatic Tracheal Masses: Perioperative Challenges.
Tracheal tumors or masses causing critical airway obstruction require resection for symptom relief. However, the location and extent of these tumors or masses often preclude conventional general anesthesia and tracheal intubation. Peripheral cardiopulmonary bypass often is required before anesthetizing these patients. ⋯ Instead, femoral vein-axillary artery venoarterial bypass was established to avoid Harlequin syndrome. Some of the challenges encountered were the development of Harlequin syndrome with risk of myocardial and cerebral ischemia, type and conduct of extracorporeal bypass, choice of monitoring sites, and provision of regional anesthesia for peripheral extracorporeal cannulations. Management of such patients needs frequent troubleshooting and multidisciplinary coordination for a successful surgical outcome.
