Summary

To explore the effects of bupivacaine liposomes in preemptive analgesia for iliofascial block on postoperative pain and postoperative delirium in elderly patients with hip fractures, to optimize perioperative analgesia strategies, to reduce the incidence of postoperative delirium, and to improve patient prognosis.

Conditions

  • Postoperative Delirium

Interventions

DRUG

Tramadol

The control group routinely injected tramadol 100mg(Tramal) intramuscularly

DRUG

bupivacaine liposome (ultrasound-guided high iliofascial space block)

the experimental group was given ultrasound-guided high iliofascial space block: High-frequency linear probe (5-13 MHZ, Sonosite, USA) was used to identify the iliac bone, iliac muscle and deep circumiliac artery. Then a short oblique puncture needle was used, with the intraplanar technique, and the needle was inserted from the outside. When the needle tip reached the surface of the iliac muscle (iliac fascia space), 20ml of bupivacaine liposome was injected. After the operation, electrocardiogram monitoring(Mindray) was performed for 1 hour to observe adverse reactions.
