Postoperative ecchymoses or hematomas can prolong healing from surgery, and a search for locally administered agents that decrease bleeding is warranted. The objective of this study is to evaluate whether preoperative subcutaneous injection of tranexamic acid (TXA) reduces intra- and postoperative bleeding or ecchymoses in skin-only upper eyelid blepharoplasty surgery.
This is a prospective randomized, double-blind, controlled study.
We included 34 consecutive patients who were referred to an upper eyelid blepharoplasty surgery in our institution.
The patients were equally randomized to a preoperative local injection of lidocaine mixed with either TXA or normal saline. All patients stopped antiaggregates 1 week before surgery. All surgeries were performed by a single surgeon who was unaware of group assignment. Total surgical time, cumulative time of cautery use, blood loss, the surgeon's assessment of bleeding extent, pain level reported by the patient, periocular ecchymoses during the first postoperative week, and time for patient's return to normal daily activity were recorded.
There was a trend toward smaller ecchymoses in the TXA group compared with the placebo group on the seventh day (p = 0.072). There were no group differences in total surgery time, cumulative cautery time, net blood weight in surgical pads, patient-reported pain level, surgeon's assessment of hemostasis, or periocular ecchymosis size on the first postoperative day.
Subcutaneous TXA was associated with similar intra- and postoperative hemorrhage in upper eyelid blepharoplasty compared with placebo. The effect of TXA in patients who did not stop antiaggregate use before surgery warrants further study.
术后瘀斑或血肿可延长手术愈合时间,因此有必要寻找局部应用可减少出血的药物。本研究旨在评估术前局部注射氨甲环酸(TXA)是否可减少单纯上眼睑成形术手术中的术中及术后出血或瘀斑。
这是一项前瞻性随机、双盲、对照研究。
我们纳入了 34 例连续就诊于我院行上眼睑成形术的患者。
患者被随机分为两组,术前分别于眼睑皮下注射利多卡因混合 TXA 或生理盐水。所有患者均于术前 1 周停用抗血小板药物。所有手术均由同一位术者进行,术者不知道分组情况。记录总手术时间、电凝使用累计时间、失血量、术者评估的出血程度、患者报告的疼痛程度、术后第 1 周眶周瘀斑情况以及患者恢复正常日常活动的时间。
与安慰剂组相比,TXA 组在第 7 天的瘀斑程度较小,但差异无统计学意义(p = 0.072)。两组在总手术时间、电凝使用累计时间、手术垫上的净失血量、患者报告的疼痛程度、术者评估的止血效果或术后第 1 天眶周瘀斑大小方面均无差异。
与安慰剂相比,上眼睑成形术中皮下注射 TXA 并未导致术中及术后出血量的显著差异。对于未在术前停用抗血小板药物的患者,TXA 的作用仍有待进一步研究。
