Observational StudyPleth Variability Index Predicts Fluid Responsiveness in Mechanically Ventilated Adults During General Anesthesia for Noncardiac Surgery.
To investigate whether the pleth variability index (PVI), derived noninvasively from a pulse oximeter probe, would predict fluid responsiveness in patients undergoing noncardiac surgeries. ⋯ Pleth variability index is predictive of fluid responsiveness in adult patients undergoing noncardiac surgery.

Persistent Kidney Injury at Hospital Discharge After Cardiac Surgery with Cardiopulmonary Bypass in Patients with Normal Preoperative Serum Creatinine and Normal Estimated Glomerular Filtration Rate.
Acute kidney injury is a serious complication after cardiac surgery. Although it resolves in most cases, a significant portion of patients persistently have raised creatinine values at hospital discharge. These patients are at greater risk for developing chronic kidney disease and mortality. Therefore, the present study aimed to ascertain risk factors of persistent acute kidney injury after cardiac surgery in patients with normal preoperative renal function. ⋯ Age ≥ 70 years, higher peak postoperative creatinine within 48 hours, and lower hemoglobin on intensive care unit arrival are associated with persistent acute kidney injury. Strategies to improve hemoglobin on intensive care unit arrival potentially can reduce persistent acute kidney injury. The authors recommend that patients aged ≥ 70 years undergo further renal evaluation for better risk stratification.
