[The importance of timely and safe care. Report of one case].

We report a 32-year-old woman with chronic kidney disease on hemodialysis undergoing a nephrectomy for left xanthogranulomatous pyelonephritis with a coralliform calculus and septic shock. Her clinical evolution was torpid, subfebrile, with persistent elevation of inflammatory parameters and with the finding of intra-abdominal collections interpreted as post-surgical. Finally faced with microbiological evidence of infection of the collections, the patient was operated and tended to improve. Subsequently, she underwent a difficult mechanical ventilation weaning, identifying the abrupt discontinuation of benzodiazepines as a contributing factor to agitation. We report this patient for educational purposes and to reinforce some quality-of-care concepts such as safety and opportunity of healthcare.
