A prospective study on use of thrive (transnasal humidified rapid insufflation ventilatory exchange) versus conventional nasal oxygenation following extubation of adult cardiac surgical patients.

Background: Postoperative pulmonary complications in cardiac surgery increase mortality and morbidity. High flow nasal cannula oxygen therapy (HFNC) is one of the preventive measures to reduce the incidence of lung complications. HFNC can decrease dyspnea and improve physiologic parameters after extubation, including respiratory rate and heart rate, compared with conventional oxygen therapy.

Role of urinary PO analysis during conventional versus conventional and modified ultrafiltration techniques in adult cardiac surgery.

Background: Medullary hypoxia is the initial critical event for kidney injury during cardiopulmonary bypass, and therefore urinary PO with its potential of detecting medullary oxygenation for its management. Therefore, we tested the role of urinary PO in predicting kidney injury in those undergoing conventional versus combined (conventional and modified) ultrafiltration during cardiac surgery in adults.

Methodology: We prospectively evaluated 32 adults between 18 and 65 years of age undergoing elective on-pump cardiac surgery with ejection fraction >35% by conventional (group C) versus combined ultrafiltration (group CM).

Early prediction of acute kidney injury using serum phosphorus as a biomarker in pediatric cardiac surgical patients.

Background: Acute kidney injury (AKI) is a strong predictor of morbidity and mortality after cardiac surgery. Lack of valid early biomarkers for predicting AKI has hampered the ability to take therapeutic measures for preventive cause. Hyperphosphatemia that occurs in AKI due to renal excretion defect was not studied in this context and could be simple marker of AKI.
