Is there any correlation between integrated pulmonary index and thoracic surgery patients’ follow-up data? a prospective, observational study

Abstract

Purpose: In this study, we investigated the relationship between integrated pulmonary index and patients’ demographic data, surgical characteristics, postoperative complications, blood gas analysis, and hemodynamic values after thoracic surgery.
 Materials and Methods: A total of 97 patients scheduled for elective thoracic surgery were included in this study. After surgery, integrated pulmonary index monitoring was performed for all patients in the post-anesthetic care unit. Patients’ characteristics, postoperative hemodynamic values, arterial blood gas analysis, length of hospital stay, postoperative complications, duration of anesthesia, and duration of surgery were recorded. Their correlations with postoperative integrated pulmonary index scores at 30 minutes, 1 hour, and 2 hours were investigated. 
 Results: Patients’ demographic data and surgical characteristics did not affect integrated pulmonary index scores. No significant correlation was found between integrated pulmonary index scores and duration of anesthesia, duration of surgery, postoperative complications, or length of hospital stay. However, there was a correlation between postoperative hemodynamic values, arterial blood gas analysis and integrated pulmonary index score. 
 Conclusion: Integrated pulmonary index monitoring is a bedside and non-invasive method that displays multiple parameters on a single screen, corraletes with arterial blood gas analysis and hemodynamic values. Therefore, it may provide advantages in early follow-up of thoracic surgery patients. However, multicenter, randomized controlled studies with a larger number of patients are needed to investigate the efficacy of integrated pulmonary index in patients undergoing thoracic surgery.
