This study is going to research the hypothesis that to strengthen the comprehensive treatment of perioperative anesthesia is possible to improve the prognosis of patients with hip fracture and reduce mortality. This is a randomized controlled pilot study aimed to elderly patients with hip fracture on one side and needing surgical treatment.

To evaluate the efficacy of perioperative anesthesia care bundle on prognosis in elderly undergoing hip fracture surgery; to assess the levels of compliance that current anesthesia management strategy of our hospital against the new "guidelines"; and to analyze the defects in the current anesthesia management strategy and collect data for further multi-center research, this single-center randomized controlled trial was conducted. The central stochastic system was adopted to determined the stratification factors by age, POSSUM score, whether there was tracheal intubation or laryngeal mask auxiliary ventilation. Therefore, there are two groups including the new version of "guidelines" anesthesia strategy group and existing anesthesia strategy group at a ratio of 1:1. The mortality is the primary indicator will be collected in 1,6,12 months after surgery. And VAS score, MMSE, length of hospital stay and so forth, which would be collected as the secondary indicators.

Inclusion Criteria:

1. Patients ≥ 75 years old;
2. Patients with hip fracture purely and surgical treatment is scheduled.

Exclusion Criteria:

1. Surgical treatment has been performed after entering hospital;
2. Multiple trauma: multiple fractures; chest, abdomen, pelvis and sacral trauma; severe head injury, etc.
3. Refuse to sign informed consent;
4. Investigator thinks he/she is inappropriate to carry out this study.
