Aggressive warming better maintained core temperature (36.5 degrees vs 36.1 degrees C) and slightly decreased intraoperative blood pressure. Aggressive warming also decreased blood loss by approximately 200 mL. Aggressive warming may thus, be beneficial in patients undergoing hip arthroplasty.

It was concluded that auricular acupressure is an effective treatment for anxiety in prehospital emergency settings.

We tested, in a double-blinded manner, the hypothesis that acupressure could be an effective pain therapy in minor-trauma patients. Our results show that acupressure is an effective and simple-to-learn treatment of pain in emergency medical care and can improve the quality of care.

Local active warming is an effective and easy to learn pain treatment for patients with acute renal colic in emergency care.
