Clinical Trial Summary

Postoperative delirium is one of the common complications in the older aldults after surgery, which can lead to longer hospita stay，memory loss and reduced quality of life. There is currently no specific treatment. Therefore, it is important to prevent the occurrence of postoperative delirium. This study investigated the effect of intranasal insulin administration on the prevention of postoperative delirium and compared different doses of insulin to find a safe and acceptable method for preventing delirium.

Description:

Hip fractures are a common trauma in older adults and occur mainly in older people with osteoporosis. Surgery is the preferred choice for the vast majority of patients with severe pain and limited mobility in older aldults with hip fractures, resulting in higher mortality and disability rates with conservative treatment. But postoperative delirium becomes a challenge. At present, the treatment of delirium includes pharmacological and non-pharmacological methods, but the effect is limited, and now the focus is on preventing delirium, so this study investigated the effect of intranasal insulin administration on the prevention of postoperative delirium.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	postoperative delirium	The CAM-ICU scale is used to evaluate whether postoperative delirium occurs in three groups of patients. The scale is divided into four parts: acute changes and fluctuations in consciousness state, attention disorders, changes in consciousness level, and cognitive confusion. If acute changes in consciousness and attention deficit occur simultaneously, combined with changes in consciousness level and cognitive confusion, either can be diagnosed as postoperative delirium.	From 18:00 to 19:00 on the 1st postoperative day, the 2nd postoperative day, and the 3rd postoperative day,
Secondary	visual analogue scale	Assess postoperative pain,0 represents painless, 10 represents severe pain, and the higher the score, the more severe the pain will be.	On the 1st postoperative day, the 2nd postoperative day, and the 3rd postoperative day,
Secondary	Lactate content in cerebrospinal fluid	The patient underwent neuraxial anesthesia to obtain 0.5ml of cerebrospinal fluid and measure the lactate content in the cerebrospinal fluid	During the anesthesia
Secondary	Blood glucose values	A blood glucose meter is used to measure the patient's fingerstick blood glucose	1 day before the operation, 40 minutes after nasal administration of insulin or normal saline, before surgery and immediately after surgery
Secondary	Glucose content in cerebrospinal fluid	The patient underwent neuraxial anesthesia to obtain 0.5ml of cerebrospinal fluid and measure the glucose content in the cerebrospinal fluid	During the anesthesia
