Effect of indwelling drainage tube and extubation time on recessive hemorrhage and functional recovery after total hip arthroplasty / 中国骨伤

ABSTRACT

OBJECTIVE@#To study and compare the effect of indwelling drainage tube and extubation time on occult hemorrhage and functional recovery after total hip arthroplasty(THA).@*METHODS@#From July 2017 to June 2018, 123 patients who underwent THA in our hospital for the first time were selected as the subjects of study. According to whether the drainage tube was retained or not and the time of extubation, they were divided into three groupsin group A, 41 patients (24 males, 17 females, age 53 to 77 years) did not put drainage tube after THA;in group B, 41 patients were removed 24 hours after THA, 26 males and 15 females, aged 55 to 74 years;in group C, 41 patients were removed 48 hours after THA, 25 males and 16 females, aged 52 to 75 years. The VAS score of pain 72 hours after THA, the total and recessive blood loss, the time of starting functional exercise, and the incidence of postoperative limb swelling were recorded. All the patients were followed up for one year after discharge. Harris hip score was used to evaluate the degree of hip function recovery one year after operation.@*RESULTS@#The occult blood loss of group A, B and C were(513.6±25.3), (521.7±33.4), (519.3±29.8) ml, respectively, with no significant difference(>0.05). There was no significant difference in blood loss in operation among the three groups(>0.05). In group B and C, the postoperative apparent blood loss was more than that in group A (0.05). The time of getting out of bed in group A was shorter than that in group B and C (0.05). There was no significant difference in the incidence of complications among three groups (>0.05).@*CONCLUSION@#Whether the drainage tube is left or not and the time of extubation have no significant effect on the latent blood loss and functional recovery after THA, but without drainage tube after THA can reduce the apparent blood loss, patients can get out of bed at 6 hours after THA, which is more conducive to the recovery and nursing of patients.
