INTRODUCTION: Humanized care is the first aspect to consider to satisfy the surgical patient who will be or has undergone a surgical intervention. OBJETIVE: Determine the relationship that exists between perceived satisfaction and humanized nursing care in surgical patients in a public hospital in Peru. METHOD: Descriptive, observational, correlational study, with a quantitative approach, with probabilistic sampling of 241 surgical patients. A validated questionnaire adapted to our reality was used, reporting a Cronbach Alpha coefficient of 0.890 (satisfaction) and 0.904 (humanized nursing care), presenting 36 multiple choice questions. RESULTS: The age group of 18-29 years predominated in 26.6% (n = 64), with the average age X = 42.6 years with a DS of 14.47, female sex with 55.2% (n = 133), single marital status 48.5% (n = 117) and secondary education level was 60.2% (n = 145). The majority of patients were satisfied with the care received, reporting 84.6% (n = 204), also found in the dimensions: Humane 81.8% (n = 197), timely 78.8% (n = 190) and safe 80.1% (n = 193). The perceived humanized nursing care was good 81.3% (n = 196), it was also evident in the dimensions: Phenomenological 78.4% (n = 189), interaction 75.9% (n = 183), scientific 61, 8% (n = 149) and human needs (82.2%) (n = 198). CONCLUSIONS: A moderate correlation was found between the variables, behaving in a moderately positive manner, that is, the higher the level of satisfaction, the higher the level of humanized nursing care in the surgical patient, and vice versa.
