All rights reserved.In our study, the purpose was to investigate the preoperative evaluations and indications of hospitalization of patients projected to be followed-up in postoperative Intensive Care Unit (ICU).A total of 77 patients who were projected to need ICU in the postoperative period and referred to postoperative ICU peroperatively as a result of preoperative evaluations for one year, were included in the study. The age, gender, ASA, type of surgery (elective/emergency), anesthesia method, postoperative stay in postoperative Intensive Care Unit and results (discharge/exitus) of the patients were recorded.In preoperative evaluation, it was determined that a total of 12.5% of patients projected to be hospitalized in postoperative ICU were referred to postoperative services. It was determined that 89.6% of patients were ASA III-V, 24.7% had malignancy, and 49.4% were operated urgently. As the indication of hospitalization at ICU, follow-up with monitoring was detected at 57.1%, hemodynamic instability at 27.3%, respiratory failure at 11.7%, and peroperative complications at 3.9%. While 92.5% of our patients were discharged with cure, 4.5% were exitus, and 3% were referred to another center. It was determined that our patients with postoperative ICU indications were elderly, male, and ASA III and above. The need for postoperative monitoring and hemodynamic instability were observed to be the most common indications for hospitalization. It was revealed that our hospital needed intermediary intensive care for the effective use of ICU capacities and optimum postoperative patient care.
