Objective: This study through the drainage tube compare primary total hip arthroplasty effect observed drainage whether will bring significant benefits , or will lead to the increase in the amount of bleeding and blood transfusion rate or cause a wound -related complications surgical treatment generated. To provide a scientific basis for the need for drainage pipe applications in total hip arthroplasty . Methods: The study was a prospective , randomized, parallel-group trial design methods , and screening to meet the standard first - line patients with total hip arthroplasty 80 cases from September 2007 to February 2009 , were randomly divided into the drainage group and non drainage group. By observing the preoperative and postoperative hematocrit hematocrit decline in value , thigh circumference change in caseload , hospital stay and postoperative Harris hip score of 3, 6, and 12 - month follow - up indicators , which is an objective evaluation of the drainage tube in total hip arthroplasty . RESULTS: Comparison of postoperative drainage group hematocrit values ??than non - drainage group , the decline in hematocrit value and blood transfusion in drainage group number of cases is higher than the non- drainage group were statistically significant (P <0.05). Drainage postoperative complications such as hematoma , infection , drainage port exudate than the number of cases occurred slightly more non - drainage group , but no significant difference . The postoperative thigh circumference values ??and no significant difference in the duration of hospitalization . The two groups after Harris score gradually improved in both groups after 12 months , there was a significant difference ( P <0.01 ) compared with before surgery . But Harris score similar postoperative group of 3 , 6 , and 12 months , no significant difference. Conclusion : In primary total hip arthroplasty , the drainage did not give surgical treatment brought about significant benefits , but it will also lead to the increase in the amount of bleeding and blood transfusion rate , and also lead to the generation of wound -related complications ; drainage pipe does not hold will affect a total hip replacement surgery patients rehabilitation exercises and functional recovery . Therefore , we recommend that for the first time to accept patients with total hip arthroplasty postoperative drainage tube can hold .
