Hemorrhage during rhinoplasty may impair the surgeon's visibility. Our objective was to examine the impact of subcutaneously administered Tranexamic acid (TXA) on bleeding during rhinoplasty.
A three-blind randomized clinical trial including 60 patients undergoing nose surgery was conducted to compare the effects of two different anesthetic solutions on surgery results. The control group received a solution consisting of 5 cc of 2% lidocaine and 0.5 cc of epinephrine 1/100000, and the TXA group received a solution containing 5 ml of 2 lidocaine, 0.25 cc of epinephrine 1/100000 and 4.75 cc of 10% TXA. To achieve a total injection volume of 10 ml in both groups, distilled water was added. Bleeding rate, hemodynamic parameters, surgeon satisfaction and overall quality of the surgical field were evaluated.
The hemodynamic parameters exhibited no notable differences between the two groups throughout the study period (P value > 0.05). The volume of bleeding observed in the TXA group was marginally greater than that in the control group (P value=0.061). Additionally, there were no significant variations in the quality of the surgical field or the satisfaction levels of the surgeon between the two groups.
In the TXA group, there was no increase in bleeding despite using a low concentration of epinephrine. Consequently, it is recommended that an injectable formulation of TXA containing a reduced concentration of epinephrine be used in surgical procedures where the use of high-concentration epinephrine is contraindicated, such as in patients with cardiovascular disease.
隆鼻手术中的出血可能会影响外科医生的视野。我们的目的是研究皮下注射氨甲环酸(TXA)对隆鼻手术中出血的影响。
进行了一项三盲随机临床试验,纳入60例接受鼻部手术的患者,比较两种不同麻醉溶液对手术效果的影响。对照组接受由5毫升2%利多卡因和0.5毫升1/100000肾上腺素组成的溶液,TXA组接受含有5毫升2%利多卡因、0.25毫升1/100000肾上腺素和4.75毫升10% TXA的溶液。为使两组的总注射量均达到10毫升,加入了蒸馏水。评估出血率、血流动力学参数、外科医生满意度和手术视野的整体质量。
在整个研究期间,两组的血流动力学参数无显著差异(P值>0.05)。TXA组观察到的出血量略高于对照组(P值=0.061)。此外,两组之间手术视野质量或外科医生满意度没有显著差异。
在TXA组中,尽管使用了低浓度的肾上腺素,但出血并未增加。因此,建议在禁忌使用高浓度肾上腺素的手术中,如心血管疾病患者,使用含较低浓度肾上腺素的TXA注射制剂。
