Valproic Acid for Hyperactive Delirium and Agitation in Critically Ill Patients.

Background: Delirium and agitation are common syndromes in critically ill patients. Valproic acid (VPA) has shown benefit in intensive care unit (ICU)-associated delirium and agitation, but further evaluation is needed.

Objective: The purpose of this study was to evaluate the effectiveness and safety of VPA for hyperactive delirium and agitation in critically ill adult patients.

Evaluating the Use of Unfractionated Heparin with Intra-Aortic Balloon Counterpulsation.

Background: Evidence supporting anticoagulation with unfractionated heparin (UFH) in patients with an intra-aortic balloon pump (IABP) to prevent limb ischaemia remains limited, while bleeding risks remain high. Monitoring heparin in this setting with anti-factor Xa (anti-Xa) is not previously described.

Objectives: The study objective is to describe the incidence of thromboembolic and bleeding events with the use of UFH in patients with an IABP utilising monitoring with both anti-Xa and activated partial thromboplastin time (aPTT).

To PLEX or Not to PLEX for Amiodarone-Induced Thyrotoxicosis.

Amiodarone-induced thyrotoxicosis (AIT) carries significant cardiovascular morbidity. There are two types of AIT with treatment including antithyroid medications and corticosteroids and treatment of ventricular arrhythmias. Therapeutic plasma exchange (TPE) also known as "PLEX" may help remove thyroid hormones and amiodarone.
