Airway and breathing management play critical role in trauma resuscitation. Early identification of esophageal intubation and detection of fatal events is critical. Authors studied the utility of integration of point-of-care ultrasound (POCUS) during different phases of rapid sequence intubation (RSI) in trauma resuscitation.
It was prospective, randomized single-centered study conducted at the Emergency Department of a level one trauma center. Patients were divided into ultrasonography (USG) and clinical examination (CE) arm. The objectives were to study the utility of POCUS in endotracheal tube placement and confirmations and identification of potentially fatal conditions as tracheal injury, midline vessels, paratracheal hematoma, vocal cord pathology, pneumothorax, and others during RSI. Patient >1 year of age were included. Time taken for procedure, number of incorrect intubations, and pathologies detected were noted. The data were collected in Microsoft Excel spread sheets and analyzed using Stata (version 11.2, Stata Corp, Texas, U. S. A) software.
One hundred and six patients were recruited. The mean time for primary survey USG versus CE arm was (20 ± 10.01 vs. 18 ± 11.03) seconds. USG detected four pneumothorax, one tracheal injury, and one paratracheal hematoma. The mean procedure time USG versus CE arm was (37.3 ± 21.92 vs. 58 ± 32.04) seconds. Eight esophageal intubations were identified in USG arm by POCUS and two in CE arm by EtCO2 values.
Integration of POCUS was useful in all three phases of RSI. It identified paratracheal hematoma, tracheal injury, and pneumothorax. It also identified esophageal intubation and confirmed main stem tracheal intubation in less time compared to five-point auscultation and capnography.
气道和呼吸管理在创伤复苏中起着关键作用。早期识别食管插管和检测致命事件至关重要。作者研究了在创伤复苏快速顺序插管(RSI)的不同阶段应用床旁超声(POCUS)的效用。
这是一项在一级创伤中心急诊科进行的前瞻性、随机单中心研究。患者被分为超声检查(USG)组和临床检查(CE)组。目的是研究POCUS在RSI期间气管内导管置入、确认以及识别潜在致命情况(如气管损伤、中线血管、气管旁血肿、声带病变、气胸等)方面的效用。纳入年龄大于1岁的患者。记录操作时间、插管错误数量以及检测到的病变情况。数据收集于Microsoft Excel电子表格中,并使用Stata(版本11.2,美国德克萨斯州Stata公司)软件进行分析。
招募了106名患者。初次检查时USG组与CE组的平均时间分别为(20±10.01秒对18±11.03秒)。USG检测到4例气胸、1例气管损伤和1例气管旁血肿。USG组与CE组的平均操作时间分别为(37.3±21.92秒对58±32.04秒)。USG组通过POCUS识别出8例食管插管,CE组通过呼气末二氧化碳(EtCO2)值识别出2例食管插管。
POCUS的应用在RSI的所有三个阶段均有用。它能识别气管旁血肿、气管损伤和气胸。与五点听诊和二氧化碳波形图相比,它还能在更短时间内识别食管插管并确认主气管插管。
