Conditions studied: Rebound Pain Impact After Hip Surgery With Nerve Block

In brief

Postoperative delirium is a significant and commonly encountered complication in patients undergoing hip surgery, particularly among the elderly. Postoperative delirium is associated with serious consequences, including prolonged intensive care unit stay, increased complication rates, higher mortality risk, and rising healthcare costs. The incidence of Postoperative delirium after hip fracture surgery has been reported to range between 13% and 55.9%, indicating a substantial clinical burden. Effective postoperative pain control is critical not only for maintaining quality of life but also for preserving cognitive well-being. In this context, peripheral nerve blocks are frequently used for pain management following hip surgery.
