ABSTRACT

Objective: To evaluate the correction of the oxygenation index in critical patients at level of the City of Mexico.
Methods: They were analyzed a total of 143 patients that admitted to the Unit of Intensive Therapy, and they were included to the study 46 patients, 21patients of the male sex: 45.65% (53.57 ± 21.18 years old) and 25 female sex 54.34% (40.24 ± 20.36 years). Which were divided in 3 groups: Group with ALI or ARDS 16 patients: Age: Female (50%) 46.5 ± 24.85 years old, Male: (50%) 61 ± 11.74 years old. Diagnostic main: Abdominal Postoperative (abdominal sepsis) 5 (31.25%); Pancreatitis 2 (12.5%) NAC (Community acquired pneumonia) 2 (12.5%), Mortality 5 (31.25%). Patient with another pathology without ALI or ARDS: 15 patients: Age: Male: 59.12 ± 19.99 years old (53.33%), Female: 55.71 ± 11.96 years old (46.66%) diagnostic: Ischemic Cardiopathy 3 (20%), Abdominal Postoperative: 3 (20%), other cardiopathy: 2 (13.33%). Mortality: 3 (20%). Group of healthy: 13 patients, Age: Male: 18.33 ± 1.52 years (23.07%); female: 24.4 ± 5.50 years old (76.92%).
Statistical analysis: Will be carried out the determination of the stocking, standard deviation, sensibility, specificity, and was carried out an parametric analysis, through test of Student t test, to check the difference between two sample stockings and their distributions.
Results: The oxygenation index or index of Kirby corrected with regard to the scale of Murray: Sensibility 100% especificity: 66%. The oxygenation index corrected with regard to the oxygenation index or index of Kirby normal: Sensibility 100%/specificity 0%. The Murray Scale with regard to the oxygenation index or index of Kirby corrected : Sensibility 28%/Specificity 100%. The oxygenation index or index of Kirby normal with regard to The oxygenation index or index of Kirby corrected: Sensibility 37.5/Specificity 0%.

    The oxygenation index or index of Kirby normal (IK)   The oxygenation index or index of Kirby corrected (IKc)
Studies group   125.8 ± 47.76   214.90 ± 81.93
Control group   209.94 ± -67.57   360.08 ± 115.95
Group healthy   209.75 ± 193.23   700.75 ± 113.05.

The mortality: 5 patients: (31.25%) 3 patients (20%)
Conclutions: 1. The correction of the oxygenation index or in the critical patients at level of the city of Mexico, is of bigger sensibility and specificity, with regard to the scales settled down in the diagnosis of the Acute Lung Injury and the ARDS.
2. The adjustment or correction according to the height or barometric pressure, are necessary to avoid overestimation the diagnose of ALI and SIRA.
3. In the group Control and the health group, one observes that if the oxygenation index or Kirby index, is not corrected, they studied with values that they could be included in the Acute Lung Injury
4. The significance statistical of the oxygenation index or Kirby index corrected with regard scales established was p ‹ 0.001
