Two years ago the authors began to use Swan-Ganz catheters to generate more complex hemodynamic data as a better guide to resuscitation of burns. This study uses the information to identify differences between survivors and nonsurvivors.
Fifty-three consecutive patients with major burns were treated using Swan-Ganz-generated data. Additional information was collected, including demographics, intake and output, medications, and arterial blood gas (including calculated oxygen consumption). Statistical analysis incorporated adjustments for autocorrelation.
The patients included 38 men and 15 women, averaged 43.7 years of age, and had a mean burn size of 40%. Thirteen patients suffered severe inhalation injury. Data collected hourly over 3 days were collapsed across 6-hour observation periods. Mean values, when plotted across time, discriminated the 37 survivors from the 16 nonsurvivors. Poor response to resuscitation as evidenced by increased use of colloid fluid and cardiotonic drugs plus failure to maximize oxygen consumption were associated with nonsurvival.
Unsustained or inadequate response to hyperdynamic resuscitation of burns was associated with nonsurvival.
两年前,作者开始使用 Swan - Ganz 导管来生成更复杂的血流动力学数据,以便更好地指导烧伤复苏。本研究利用这些信息来确定幸存者与非幸存者之间的差异。
连续 53 例重度烧伤患者接受了基于 Swan - Ganz 导管生成数据的治疗。收集了其他信息,包括人口统计学数据、出入量、用药情况以及动脉血气(包括计算得出的氧耗量)。统计分析纳入了对自相关的校正。
患者包括 38 名男性和 15 名女性,平均年龄 43.7 岁,平均烧伤面积为 40%。13 例患者遭受了严重吸入性损伤。在 3 天内每小时收集的数据被汇总为 6 小时观察期的数据。随着时间绘制的平均值区分出了 37 名幸存者和 16 名非幸存者。胶体液和强心药物使用增加以及未能使氧耗量最大化所证明的对复苏反应不佳与非存活相关。
对烧伤高动力复苏的反应持续不佳或不充分与非存活相关。
