Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Incidence of postoperative delirium

    Confusion Assessment Method (CAM) was recorded before surgery, 10 min after admission to PACU, before exiting the post-anesthesia care unit (PACU), and 1, 2, and 3 days after surgery. POD was diagnosed if the patient had at least one episode of delirium at these time points after surgery. The CAM diagnostic algorithm is based on four cardinal features of delirium: 1) acute onset and fluctuating course, 2) inattention, 3) disorganized thinking, and 4) altered level of consciousness. A diagnosis of delirium according to the CAM requires the presence of features 1, 2, and either 3 or 4.

    Within 3 days after surgery

Secondary Outcomes (2)

  • Incidence of intraoperative hypothermia

    During operation

  • Pleiotropic cytokine in the patient's serum

    Serum interleukin-6 (IL-6) levels before surgery and at 1, 2, and 3 days after surgery.

Study Arms (2)

Group C

NO INTERVENTION

Patients in Group C will be covered with a bedsheet intraoperatively without active warming methods employed.

Group W

EXPERIMENTAL

Patients in Group W will have a 37°C forced-air warming blanket initiated upon entering the operating room to maintain their body temperature between 36-37 degrees Celsius.

Device: 3M™ Bair Hugger™ Warming Unit

Interventions

Utilizing the 3M Temperature Management Unit to ensure intraoperative body temperature of elderly hip surgery patients remains consistent with their preoperative baseline, while patients in Group C receive no intervention.

Group W
