Abstract:
30 kg/m2 served as obesity group.Using Gross formula,the true total blood loss was calculated depending on the height,body mass and pre-and post-operative Hct,and hidden blood loss was gotten by subtracting the visible blood loss from total loss.③The correlation between visible and hidden blood loss was observed.RESULTS:All 41 patients undergoing THA and 37 TKA were involved in the result analysis.①Following THA,the mean total loss was 1 520 mL and the hidden blood loss 482 mL(32%).Following TKA,the mean total loss was 1 508 mL and the hidden blood loss was 776 mL(52%).The hidden blood loss between THA and TKA was significantly different(P 0.05).CONCLUSION:①The hidden blood loss in TKA is far higher than THA.It is very important to supplement the blood volume during TKA for the insufficiency to regain general circulation although using blood re-infusion.②It may improve clinical evaluation capabilities to estimate hidden blood loss and thus result in better patient care after joint arthroplasty.
