Effect of Weighted Blanket Versus Traditional Practices on Anxiety and Pain in Patients Undergoing Elective Surgery: A Multicenter Randomized Controlled Trial.

Perioperative anxiety is common in surgical patients and linked to poor outcomes. This multicenter randomized controlled trial assessed the effect of the use of a warm weighted blanket on presurgical anxiety and pain, as well as postsurgical restlessness, nausea, and vomiting. Levels of anxiety and pain were measured in adult patients using a 100-point visual analog scale before elective surgery.
