The Duration of Prophylactic Antibiotic Use for Esophageal Cancer Patients with Postoperative Infection and Nutritional Status

This study verified the hypothesis that "antibiotic use time ≤24 hours is associated with a lower infection rate trend and an increase in nutritional indicators", but the causal relationship could not be established due to the retrospective design. Age, pulmonary ventilation function, length of hospital stay, and preoperative malnutrition were independent risk factors for postoperative infection, supporting the clinical formulation of individualized antibiotic regimens based on the association between medication duration and infection/nutrition.
