Zhao F, et al. - In elderly patients with intertrochanteric fracture, experts gauged the risk factors for perioperative death. In elderly patients with intertrochanteric fracture and chronic diseases of major organs, BNP and APACHE II score could be used as important reference indexes for predicting possible perioperative mortality. They noted a probability of the complications following fracture to be also the risk factors. Findings suggested a statistically significant difference in the chronic diseases of major organs (heart, brain, and lung), postoperative complications, and various indicators within 24 h after admission (albumin, hemoglobin, brain natriuretic peptide [BNP], glucose, creatinine, arterial blood pH, PaO2, and APACHE II).
