In this study, we investigated the effect of reverse Trendelenburg position (RTP), with five, ten, and twenty degrees, on intraoperative bleeding and postoperative edema and ecchymosis around the eye in open rhinoplasty operations.
Ninety patients undergoing open rhinoplasty were divided into three groups, 5° angle RTP (Group 5; n = 30), 10° angle RTP (Group 10; n = 30), and 20° angle RTP (Group 20; n = 30). After 3 min of preoxygenation, anesthesia was induced with 3 mg.kg propofol, 1 μg.kg fentanyl, and 0.6 mg/kg rocuronium for muscle relaxation. Maintenance of anesthesia was provided with a minimum alveolar concentration of 1-1.5 with sevoflurane, 1:1 O2/N2O. Hemodynamic variables, intraoperational bleeding, postoperative 1st, 3rd and 7th days ecchymosis and edema around the eyes of the patients were compared between the groups.
Edema changes on postoperative 1st, 3rd and 7th days and ecchymosis changes around the eyes on postoperative 1st and 3rd days in Group 20 were found significantly lower than Group 5 (p < 0.017). Besides, the change of ecchymosis on the postoperative 1st day was found significantly lower in Group 20 compared to Group 10 (p < 0.017). The amount of intraoperative bleeding and surgical field evaluation score were found to be significantly lower in Group 10 and Group 20 compared to Group 5 (p < 0.017).
We concluded that in open rhinoplasty surgeries, 20° degree RTP reduces intraoperative blood loss and provides a more bloodless surgical field, as well as reducing edema and ecchymoses around the eyes in the postoperative period.
本研究旨在探讨反特伦德伦堡体位(RTP),5°、10°和 20°,对开放式鼻整形手术术中出血以及术后眼部周围水肿和瘀斑的影响。
90 例行开放式鼻整形术的患者分为三组:5°角 RTP(组 5,n=30)、10°角 RTP(组 10,n=30)和 20°角 RTP(组 20,n=30)。预充氧 3 分钟后,使用 3mg/kg 丙泊酚、1μg/kg 芬太尼和 0.6mg/kg 罗库溴铵诱导麻醉。维持麻醉采用 1-1.5 浓度的七氟醚和 1:1 的 O2/N2O。比较各组患者的血流动力学变量、术中出血量、术后第 1、3 和 7 天眼部周围的瘀斑和水肿。
组 20 患者术后第 1、3 和 7 天的水肿变化以及术后第 1 和 3 天眼部周围的瘀斑变化明显低于组 5(p<0.017)。此外,与组 10 相比,组 20 患者术后第 1 天的瘀斑变化明显较低(p<0.017)。与组 5 相比,组 10 和组 20 患者的术中出血量和手术视野评估评分明显较低(p<0.017)。
我们的结论是,在开放式鼻整形手术中,20°RTP 可减少术中出血量,并提供更无血的手术视野,同时减少术后眼部周围的水肿和瘀斑。
