ICU patient's body mass index and the critical care outcome: morbidity and mortality
Intensive Care Medicine Experimental volume 3, Article number: A971 (2015)
The results of ENSANUT 2012 showed that in a sample of 38208 adults showed 32.4% obesity, besides the increase of 1.3% annually from 2000 through 2012; in the US is reported 66-75% of overweight and obesity in ICU patients; recent studies have shown that obesity, paradoxically, a protective factor in patients admitted to the ICU for surgical pathology.
To report the prevalence of overweight and obesity in the ICU of Hospital Juárez of Mexico (HJM), analyzing the correlation of BMI with AKI, ARDS, LOS
254 cases of ICU January 1 to December 31, 2013 were reviewed, demographic variables, height, weight ingress and egress, ingress and egress BMI, admission diagnosis, APACHE II, SOFA recorded , TISS, presence of acute kidney injury (AKI), acute respiratory failure (ARDS), mechanical ventilatory support days (MVS), length of stay in ICU and reason for ICU discharge. The correlation between baseline BMI and the prevalence of AKI, SIRA, AMV days, length of stay in ICU and mortality were analyzed using descriptive statistics.
The total of 254 records of patients admitted during 2013 were reviewed, data of 108 cases were obtained, were organized into 6 groups according to BMI < 20 (n = 5, 4.62%), 20 to 24.9 (n = 20, 18.51%), 25 to 29.9 (n = 43, 39.81%) 30 34.9 (n = 20, 18.51%) 35 39.9 (n = 14, 12.96%) and> 40 (n = 6, 5.55%) of which 60 were women and 48 men; according to the above groups MVS days were 16, 9.5, 7.48, 17.2, 17.7 and 21.5; the length of stay in ICU: 24.4, 12.1, 12.5, 19.15, 20.5, 23.1; survival in the 6 groups was 80%, 90%, 86%, 85%, 78%, 83%; APACHE II scores averaged joint was 19.8, 14.8, 16, 20.1, 22.1, 23.8, whereas SOFA: 7.8, 6.85, 7.9, 9.35, 10.7, 11.5; and TISS average was 35.6, 35.1, 32, 28.5, 34.9, 42.
Each BMI has few patients to compare the data in an appropriate way, however, can observe the similarity between BMI of 20 to 24.9 and 25 to 29.9 kg / m2, having duration of MVS, comparable ICU stay; survival was higher in the group of normal BMI over all other groups, with lower APACHE II and SOFA estimated income. The statistic UCIA the HJM is similar to that reported in the international literature, however, no subgroups of patients according to diagnosis were analyzed, so we can not corroborate the "paradox of obese surgical patient". Interesting correlation between BMI, AKI, ARDS and LOS.
