The effects of 5-degree, 10-degree and 20-degree reverse Trendelenburg positions on intraoperative bleeding and postoperative Edemea and ecchymosis around the eye in open rhinoplasty

Purpose: 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. Materials and methods: Ninety patients undergoing open rhinoplasty were divided into three groups, 5 degrees angle RTP (Group 5; n = 30), 10 degrees angle RTP (Group 10; n = 30), and 20 degrees angle RTP (Group 20; n = 30). After 3 min of preoxygenation, anesthesia was induced with 3 mg.kg(-1) propofol, 1 mu g.kg(-1) fentanyl, and 0.6 mg/kg rocumnium 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. Results: 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). Conclusion: We concluded that in open rhinoplasty surgeries, 20 degrees 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.

Automated summary

The study showed that in open rhinoplasty surgeries, a 20-degree reverse Trendelenburg position can reduce intraoperative blood loss, provide a more bloodless surgical field, and decrease edema and ecchymoses around the eyes in the postoperative period.
