Abstract:

BACKGROUND: The swelling of limbs after total joint arthroplasty is associated with the hidden blood loss. The main component of horse chestnut seed extract is Aescine, which can protect blood vessels, increase vascular tension, reduce capillary permeability, and exert anti-edema, anti-inflammation, and anti-exudation effect. This extract can prevent and treat post-traumatic swelling of the limbs.
OBJECTIVE: To investigate the pathological mechanisms and effects of horse chestnut seed extract on early hidden blood loss and limb circumference changes after total knee arthroplasty.
METHODS: A total of 150 patients undergoing total knee arthroplasty from January 2013 to September 2013 were retrospectively analyzed. The involved cases were divided into two groups. The test group of 85 cases received oral administration of 0.3 g horse chestnut seed extract, three administrations per day, from the first day after total knee arthroplasty. The administration was given for 14 days. Control group of 65 patients received no 
detumescence drugs. There were no significant differences in patient’s age, body height and body mass index between two groups (P > 0.05). Blood routine examination was performed at 1-3 days after total knee arthroplasty. The amounts of intraoperative blood loss, postoperative blood loss, and postoperative blood transfusion were recorded. The hidden blood loss was calculated according to the Gross formula. Perioperative limb circumference above the knees was observed and measured. Two-independent-sample t-test was used to compare the difference between the two groups.
RESULTS AND CONCLUSION: Hidden blood loss between the test group and control group was (590.6±214.2) and (821.2±457.30) mL, respectively, the difference was significant (t=3.238, P=0.021). The postoperative total blood loss and the thigh circumference changes above knee in test group were less significantly than that in control group within 2 and 3 days after surgery (P < 0.05). And there was no statistically significant difference in thigh circumference changes on postoperative 1 day and drainage between the two groups (P > 0.05). Experimental findings indicate that, early application of horse chestnut seed extract can significantly reduce hidden blood loss, significantly relieve postoperative limb swelling, and promote the recovery of limb function after primary total knee arthroplasty. The mechanism of detumescence might be due to the decrease of hidden blood loss and the promotion of venous return.
