Sepsis is a complication resulting from an unbalanced immune response to an infectious focus. Abdominal sepsis is an inflammatory process of the peritoneum caused by pathogenic germs, localized or diffuse. Objective: Describe nursing care in the care of pediatric patients diagnosed with sepsis. Methodology: Qualitative research, single case type of study, executed with the nursing care process method (PAE), applying Marjory Gordon's assessment instrument to a 12-year-old male patient; Diagnoses and care planning were formulated according to the NANDA-I, NOC and NIC taxonomy; The evaluation was carried out taking into account the results of the difference in baseline and final scores, obtaining scores of +1 and +1. Results: Nine altered nursing diagnoses were identified, the main nursing diagnosis (00007) Hyperthermia r/c high metabolic rate m/p temperature of 39°, hot skin and tachycardia and the main CR of septic shock were prioritized. The nursing interventions were effective, the patient improved his thermoregulation problem and, given the CR risk of septic shock, the results are in the process of improvement.Conclusions: the clinical characteristics of the pediatric patient with a diagnosis of sepsis were identified, as well as the risk factors that could complicate health, nursing interventions and preventive care were classified and prioritized to reduce the risk of complications, based on the PAE. An individual care plan was developed that allowed him to progressively improve his health condition.
