The aim of this study is to evaluate the effect of Positive End Expiratory Pressure (PEEP) on surgical field bleeding and its respiratory and hemodynamic consequences in rhinoplasty surgeries.
This single-blind clinical trial performed in Amir Al-Momenin university Hospital in 2018. Seventy cases of rhinoplasty surgery patients Enrolled and were randomized into two groups; intervention (PEEP = 5) and comparison group (PEEP = 0). Surgical field bleeding and arterial oxygen saturation pulmonary dynamics and hemodynamic parameters were evaluated during operation and in post anesthesia care unit. Data were analyzed by SPSS software using descriptive and analytical statistics.
PEEP applying had no negative effect on surgical bleeding as well as surgeon satisfaction, heart rate and blood pressure were similar in two groups. Pulmonary dynamics and oxygenation were stable and within normal values in all cases. The mean peak airway pressure was 17.87 ± 2.24 in the PEEP group and 16.08 ± 3.37 in the ZEEP group (P = 0.029).
applying low level PEEP during anesthesia improved recovery oxygen saturation but had no negative effects on the patient`s hemodynamics, and did not aggravate bleeding and visual clarity.

本研究旨在评估呼气末正压通气（PEEP）对隆鼻手术术野出血及其呼吸和血流动力学影响。
本单盲临床试验于2018年在阿米尔·穆民大学医院进行。纳入70例隆鼻手术患者并随机分为两组；干预组（PEEP = 5）和对照组（PEEP = 0）。在手术期间及麻醉后护理单元评估术野出血、动脉血氧饱和度、肺动力学和血流动力学参数。数据采用SPSS软件进行描述性和分析性统计分析。
应用PEEP对手术出血无负面影响，两组患者的心率和血压相似。所有病例的肺动力学和氧合均稳定且在正常范围内。PEEP组平均气道峰压为17.87±2.24，零PEEP组为16.08±3.37（P = 0.029）。
麻醉期间应用低水平PEEP可改善氧饱和度恢复，但对患者血流动力学无负面影响，且不加重出血和视野清晰度。
