The Effects of Anesthesia Type on the Prognosis of Hip Fracture Surgery on Elderly Patients

Study Overview
=================
Brief Summary
-----------------
The aim of this study is to figure out whether anesthesia type have an influence on the prognosis of hip fracture surgery.30-day mortality and morbidity after the surgery are our main observational index,and according to literature and our experience,regional anesthesia may have a better prognosis after hip fracture surgery compared with general anesthesia.

Detailed Description
-----------------
Hip fracture is a common disease among elderly people,and has a high mortality and morbidity.But,seldom practice can be done to improve this condition.For a long time,whether anesthesia type could influence the prognosis after surgery is controversial.Several studies have confirmed regional anesthesia may be better for patients for its fewer complications.But most studies are retrospective,and information may be less convincing .Besides,as a matter of fact,patients of different anesthesia type may have different status,so,a scoring system may be need for comparing the status of patients of different groups. Our study is a prospective observational trial.Patients needing hip fracture surgery are divided into two groups according to the anesthesia type during surgery:Regional Anesthesia group(RA),General Anesthesia group(GA).To evaluate the status of patients before surgery,we use Orthopedic POSSUM scoring system.It consists of 12 physiological factors and 6 operative severity factors.Then,we will observe outcome of the two groups and record every complication after surgery.Finally,the initial and adjusted morbidity and mortality according to Orthopedic POSSUM scoring system of the two groups are compared.
