Serial Sonographic Assessment of Pulmonary Edema in Patients With Hypertensive Acute Heart Failure.

Objectives: Objective measures of clinical improvement in patients with acute heart failure (AHF) are lacking. The aim of this study was to determine whether repeated lung sonography could semiquantitatively capture changes in pulmonary edema (B-lines) in patients with hypertensive AHF early in the course of treatment.

Methods: We conducted a feasibility study in a cohort of adults with acute onset of dyspnea, severe hypertension in the field or at triage (systolic blood pressure ≥ 180 mm Hg), and a presumptive diagnosis of AHF.

Sudden cardiac death in a dialysis patient: hyperkalemia reconsidered.

Background: To many physicians, hyperkalemia is the first diagnosis ascribed to any patient with end-stage renal disease and abnormal electrocardiographic morphologies or dysrhythmias.

Case Report: A 52-year-old man with end-stage renal disease presented in cardiac arrest. The patient was initially presumed to have hyperkalemia, based on the appearance of wide QRS complexes on the monitor.

Successful intraoperative spinal cord monitoring during scoliosis surgery using a total intravenous anesthetic regimen including dexmedetomidine.

Intraoperative neurophysiological monitoring (IONM) during corrective spinal surgery is widely used. Because of the possible interference with the recording of evoked potentials by inhalational anesthetics, total intravenous anesthetic (TIVA) regimens have been advocated. TIVA regimens may be difficult to use in pediatric populations due to metabolic factors.
