Temperature Management on Postoperative Delirium

Effect of Intraoperative Temperature Management on Postoperative Delirium in Elderly Patients Undergoing Hip Surgery

Presently, the effects of perioperative temperature management on postoperative delirium remain ambiguous. This study endeavors to explore the influence of intraoperative temperature variations in elderly hip fracture patients on postoperative delirium.

At present, the pathophysiological mechanisms contributing to postoperative delirium in elderly hip fracture patients remain elusive, with predominant research concentrating on neural inflammation, neurotransmitter dysregulation, and metabolic irregularities. The influence of perioperative temperature management on postoperative delirium remains uncertain and may correlate with surgical modality and intraoperative temperature modulation. Hence, this study endeavors to juxtapose intraoperative temperature variations among elderly hip fracture patients, probing their ramifications on postoperative delirium.
