POSTOPERATIVE COMPLICATION
The results of this study showed that compared with the control group, the patients in the test group received FICB earlier, and their satisfaction with analgesia was improved. The maximum NRS of patients in the test group was lower, and the duration of the maximum NRS and duration of NRS > 3 was shorter.It has been widely recognized that the perioperative management of hip fractures, especially pain management, requires multidisciplinary cooperation. In this study, the results of the new mode of pain management were better than those of the control group. The primary reason for this is multidisciplinary cooperation. Multidisciplinary collaborative management for elderly hip fracture patients should involve the participation of emergency doctors, anaesthesiologists and orthopaedic doctors. Its contents include standardized first-aid procedures, comprehensive analgesic programmes, preoperative evaluation and treatment, early surgery and early discharge [Sufficient information exchange and feedback between different departments is the core of the new mode. With the progress of information science and technology, medical informatization has gradually become an important development trend. As a widely used information medium, instant messaging software provides users with more rapid, convenient and comprehensive cross-platform support. It has the characteristics of interactivity and immediacy. Using the universality of the network to promote the exchange and transmission of information, such software can meet the needs of users for instant information, provide a communication platform for team information communication, and make people's communication no longer limited by time, geographical location and space.With the help of instant messaging software, medical personnel participating in preoperative pain management can share information, communicate fully, give feedback in a timely manner and make common progress. The timeliness of information exchange makes the formulation and adjustment of analgesic programme more efficient and effective. The individualized analgesic programme can improve the level of pain management and patient satisfaction. Especially in FICB operation, the operator can live broadcast the real-time picture of puncture in software video, including the operator's specific actions and ultrasound images. In cases of a difficult procedure where the operator is not skilled enough, other doctors can remotely guide the operator to complete the block in real time to improve the success rate. In this study, the experimental group completed FICB earlier, which is precisely because of this approach.At the same time, under the new mode, medical staff are more familiar with patient information, especially when transferring them from the emergency department to the orthopaedics department. Medical staff have enough knowledge of the general situation and analgesia status of the patients, which will make patients feel more at ease and increase their overall satisfaction.The new mode in this study showed a better analgesic effect, which was directly due to the early implementation of FICB.A nerve block is an important part of the treatment plan for hip fracture patients and a key factor for success. Many previous studies have confirmed that single nerve block, especially FICB technology, has shown good analgesic effects in the preoperative analgesia of hip fracture in prehospital emergency settings and in emergency rooms [Adequate analgesia can reduce the incidence of POD in elderly patients. POD is an important factor affecting the prognosis of elderly patients. POD is an acute and reversible mental disorder characterized by changes in the level of consciousness and attention disorders after surgery and is a common postoperative complication of the central nervous system in elderly patients [This study attempted to determine the preventive effect of preoperative analgesia on POD. The MMSE scale was used to compare the cognitive function of the two groups of patients when they were admitted to the hospital because cognitive function change is an independent risk factor for delirium after orthopaedic surgery in the elderly [
