title: [Determination of postoperative hemoglobin levels and their correlation with the weight of the transoperative textiles].
abstract: OBJECTIVE
  To determine postsurgical hemoglobin levels and the correlation with trans-surgical textile weight.
  
  
  METHODS
  A cross-sectional study, including 120 patients who underwent gynecological surgery, was performed in the HGR 1 in Cd. Obregon Sonora, from June to July 2015; the account of textile weight blood loss estimation was carried out and subsequently became an association of hemoglobin levels in the postoperative period, performing the conversion of a gram to one milliliter. There was expected to be an association between blood loss with low levels of hemoglobin; for each lost 500 ml, the hemoglobin decreased by 1 g.
  
  
  RESULTS
  120 patients were evaluated; the average age was 48.65 years. The surgical events were divided in abdominal in 76.67%, breast surgery 19.17%, and vaginal 9.17%. There was a decrease in hemoglobin of 0.74 mg/dl and hematocrit of 1.93%. We found significant association between blood loss and the decrease in hemoglobin with relative risk of 3.01 (95% CI: 1.69-5.36).
  
  
  CONCLUSIONS
  The main conclusion of this study is to establish that a loss > 500 ml has a direct association with > 1.1 g postoperative hemoglobin decrease and hematocrit reduction > 6%.
