Introduction: Humanized nursing care refers to a comprehensive, patient-centered approach that seeks to address not only the physical, but also the emotional and psychological needs of the individual during their experience in the health care system. Objective: to describe the relationship between humanized nursing care and immediate postoperative patient satisfaction in Post-Anesthesia Recovery Units. Methods: A bibliographic review was carried out using the articles retrieved from the PubMed, MEDLINE, and Scielo databases, in the period between July and August 2024. Filters were used to select articles in Spanish and English. A total of 32 references were selected, which specifically fit the topic in question, excluding those with possible biases in their methods. Development: Humanized nursing care and patient satisfaction are topics of increasing relevance in the health field, especially in hospital settings such as the Post-Anesthesia Recovery Unit (URPA). Patient satisfaction, on the other hand, is a key indicator of the quality of care and is closely related to the patient's perception of the care received. Conclusions: The satisfaction and comfort of patients admitted to surgical and post-anesthesia units depends largely on the preparation provided by the nursing staff, which contributes to their prompt recovery. Better preparation is a pillar for optimal care for all those patients seeking relief after a medical intervention that affects their quality of life
