Abstract:

BACKGROUND: The hidden blood loss, accounted for a fairly large proportion of perioperative blood loss in total hip replacement, can seriously affect the recovery of postoperative joint function, but the specific influential factors and mechanisms remain unknown at present.
OBJECTIVE: To evaluate the relative influential factors for hidden blood loss after primary total hip arthroplasty by the blood loss condition, and to analyze the association between hidden blood loss and prognosis.
METHODS: Clinical data of 110 patients who underwent primary total hip arthroplasty in the Liuzhou Worker’s Hospital between April 2011 and April 2013 were retrospectively analyzed. The hidden blood loss was calculated according to Ward and Gross formula. The effects of patient’s gender, age, body mass index, type of prosthesis, presence of internal diseases, and different causes of a disease on hidden blood loss after arthroplasty were analyzed. The patients were divided into the high blood loss group (≥ 480 mL) and the low blood loss group (< 480 mL) according to the hidden blood loss. All the patients were followed up for 1 year. The Harris hip score system was used to assess the recovery of hip joint function between the two groups. The correlation between hidden blood loss and the recovery of joint function was analyzed using Pearson’s correlation analysis
RESULTS AND CONCLUSION: The total blood loss of primary total hip arthroplasty was (1 340±367) mL, and the hidden blood loss was (748±324) mL, and the percentage of hidden blood loss was 53.7%. The type of prosthesis, presence of internal diseases, and different causes of a disease were significantly associated with 
hidden blood loss after total hip arthroplasty (P < 0.05). Gender, age, body mass index, and operation time were not significantly associated with hidden blood loss after total hip arthroplasty (P > 0.05). The hidden blood loss was correlated with postoperative functional recovery (P=0.046). Results indicated that type of prosthesis, presence of internal diseases, and different causes of a disease are main influential factors for hidden blood loss after total hip arthroplasty. The hidden blood loss has some influence on the recovery of postoperative joint function.
