Abstract Objective To compare the difference and clinical effect between drainage tube and non-drainage tube after total hip arthroplasty with direct anterior approach(DAA).Methods From January 2018 to December 2018,a total of 50 cases that had total hip arthroplasty were enrolled.There were 27 left and 23 right hip joints,including 28 males and 22 females.Among them,25 cases had drainage tube and 25 caseshad no drainage tube.Bioprosthesis was used in all cases.All patients accepted articular cavity injectionwith 20 mL saline plus 1.0 g tranexamic acid.The drainage tube group clamped the drainage tube and opened it in the next morning.The drainage tube was removed 24~48 hours later.We compared the levels of hemoglobin and hematocrit at 24 hours and 3 days after operation,pain degree,wound healing and Harris hip score at half a year after operation.Results There were no significant differences in hemoglobin and hematocrit at 24 hours and 3 days after operation,pain degree and Harris score at one year after operation between the two groups(P<0.05).Conclusion For direct anteriorapproach total hip arthroplasty,no drainage tube will not affect the clinical effect,not increase the incidence of complications,reduce the nursing process.It is recommended that drainage tube should not to be placed routinely.
