OBJECTIVE
To examine whether BMI impacts the outcomes of mechanically ventilated patients.
METHODS
Data was collected retrospectively among patients involved in motor vehicle accidents in intensive care at a major trauma center in Atlanta, GA. Patients were categorized into five BMI groups: underweight (BMI < 18.5), normal weight (BMI of 18.5-24.9), overweight (BMI of 25-29.9), obese (BMI of 30-39.9), and morbidly obese (BMI of >40).
RESULTS
Among all patients (n=2,802), 3% of patients were underweight, 34% were of normal weight, 30% were overweight, 27% were obese, and 6% were morbidly obese. The mean number of ventilator days for normal weight patients was 4.6, whereas the mean number of ventilator days for underweight and morbidly obese patients were higher (10.3 and 7.4, respectively).
CONCLUSIONS
Underweight and morbidly obese populations may require additional interventions during their ICU stays to address the challenges presented by having an unhealthy BMI.
目的
研究 BMI 是否会影响机械通气患者的预后。
方法
数据从佐治亚州亚特兰大一家大型创伤中心的重症监护室中涉及车祸的患者中进行回顾性收集。患者分为五个 BMI 组：体重过轻（BMI<18.5）、正常体重（BMI 为 18.5-24.9）、超重（BMI 为 25-29.9）、肥胖（BMI 为 30-39.9）和病态肥胖（BMI>40）。
结果
在所有患者（n=2802）中，3%的患者体重过轻，34%的患者为正常体重，30%的患者超重，27%的患者肥胖，6%的患者病态肥胖。正常体重患者的平均呼吸机使用天数为 4.6 天，而体重过轻和病态肥胖患者的平均呼吸机使用天数更高（分别为 10.3 和 7.4 天）。
结论
在 ICU 期间，体重过轻和病态肥胖人群可能需要额外的干预措施来应对 BMI 不健康带来的挑战。
