The incidence of central venous catheter-related thrombosis and the long-term effects of thrombosis on catheterized veins in neonates are unknown. The authors therefore determined the incidence of central venous thrombosis, identified associated risk factors, and evaluated outcomes at 6 months. ⋯ Covert central venous thrombosis is frequent in neonates who have central venous catheters, and complications are most common in patients who have large intravascular thrombi. Neonates with large intravascular thrombi should be followed and considered for anticoagulation.

The effect of intraoperative midazolam on postoperative delirium in older surgical patients: a prospective, multicentre cohort study.
Midazolam is a short-acting benzodiazepine frequently used in the perioperative setting. This study aimed to investigate the potential impact of intraoperative midazolam on postoperative delirium in older patients undergoing noncardiac surgery. ⋯ Intraoperative administration of midazolam may not be associated with an increased risk of postoperative delirium in older patients undergoing noncardiac surgery.

The clinical use of four-factor prothrombin complex concentrate in adult trauma patients at risk of bleeding is supported by evidence for urgent reversal of oral anticoagulants but is controversial in acquired traumatic coagulopathy.

Recent evidence indicates that general anesthesia and sleep-wake behavior share some overlapping neural substrates. γ-Aminobutyric acid-mediated (GABAergic) neurons in the central amygdala have a high firing rate during wakefulness and play a role in regulating arousal-related behaviors. The objective of this study was to investigate whether central amygdala GABAergic neurons participate in the regulation of isoflurane general anesthesia and uncover the underlying neural circuitry. ⋯ The results suggest that central amygdala GABAergic neurons play a role in general anesthesia regulation, which facilitates behavioral and cortical emergence from isoflurane anesthesia through the GABAergic central amygdala-basal forebrain pathway.
