| Objective To investigate the blood loss after total knee arthroplasty (TKA) in elderly patients at high altitude and the corresponding intervention timing, intervention measures and effects. Methods The overall blood loss of 62 patients aged over 60 years old who underwent the initial unilateral total knee replacement in our department from May 2017 to May 2018 were retrospectively analyzed, assessing their intervention timing, intervention measures and effects Results The total blood loss in patients after total knee arthroplasty was (1 184.2±192.3) mL, (1 392.0±155.7) mL, (1 364.3±173.4) mL, respectively at 1 day, 3 days and 7 days postoperatively. In subgroup analysis, the total blood loss in patients aged below 70 after total knee arthroplasty was (1 181.8±192.3) mL、(1 398.4±148.1) mL、(1 437.4±173.6) mL, respectively at 1 day, 3 days and 7 days postoperatively,the total blood loss in patients aged above 70 after total knee arthroplasty was (1 174.2±167.4) mL、(1 277.5±172.6) mL、(1 298.0±141.9) mL, respectively at 1 day, 3 days and 7 days postoperatively, no significant difference was found between them(P>0.05). Eighteen patients complained postoperative poor mental state and obvious fatigue,their hemoglobin level was higher than 80 g/L, but the total blood loss was (1 397.1±168.4) mL, some Qixue traditional Chinese medicine were used and these symptoms was relieved. Conclusion There is no significant difference of the total blood loss after total knee arthroplasty in patients at high altitude when compared with those in the plain region. A postoperative routine use of Qixue traditional Chinese medicine(TCM) in patients at high altitude after TKA may be of significant clinical value to improve the postoperative blood loss and those clinical symptoms associated with blood loss. |
