Brief Summary:
Elderly patients with hip fracture are older and have a high incidence of perioperative complications. the postoperative recovery of elderly patients with hip fracture is affected by hemodynamic instability and pain caused by fracture. S-ketamine is the S-isomer of ketamine. Compared with traditional ketamine, S-ketamine has stronger analgesic effect and fewer adverse reactions of nervous system. The parasympathetic effect of S-ketamine can antagonize the circulatory inhibition of propofol and make the hemodynamics more stable in elderly patients with hip fracture.Iliac fascial space block (fasciailiacacompartmentblock,FICB) mainly depends on local anesthetics spreading to the femoral nerve, lateral femoral cutaneous nerve and obturator nerve in the iliofascial space to achieve analgesia in its dominant area. Ultrasound-guided iliac fascial space block can effectively reduce the amount of anesthetics and has shorter puncture time and fewer complications. It can more effectively reduce the perioperative pain of elderly patients with hip fracture.
Detailed Description:
With the advent of the aging society, the incidence of hip fracture in elderly patients is increasing year by year, and the incidence of perioperative neurological cognitive impairment (PND) is increasing year by year. PND refers to postoperative brain dysfunction in patients without mental disorders, including postoperative delirium POD and postoperative cognitive dysfunction POCD. PND is more common in clinic, especially in the elderly. The main feature of PND is the long-term decline and decline of cognitive function after operation. PND not only prolongs the length of stay of patients, interferes with postoperative treatment, but even increases mortality. The pathogenesis of PND is not clear, and it is affected by many factors. Studies have shown that keeping intraoperative blood pressure at baseline to 10% above baseline can significantly reduce the incidence of PND. In addition, pain is also an important factor leading to the occurrence of PND. S-ketamine is the S-isomer of ketamine. Compared with traditional ketamine, S-ketamine has stronger analgesic effect and fewer adverse reactions of nervous system. The parasympathetic effect of S-ketamine can antagonize the circulatory inhibition of propofol and make the hemodynamics more stable. Iliac fascial space block (fasciailiacacompartmentblock,FICB) mainly depends on local anesthetics spreading to the femoral nerve, lateral femoral cutaneous nerve and obturator nerve in the iliofascial space to achieve analgesia in its dominant area. Ultrasound-guided iliac fascial space block can effectively reduce the amount of anesthetics and has shorter puncture time and fewer complications. In this study, a randomized controlled trial was conducted to observe the clinical effects of S-ketamine and ultrasound-guided iliac fascia block combined with general anesthesia in elderly patients with hip fracture, and to evaluate their clinical value.
