Abstract

Background: The postoperative neutrophil-to-lymphocyte ratio (NLR) and change in NLR (ΔNLR) are known as independent prognostic factors of postoperative survival in patients who underwent lung resection. Unlike conventional thoracic surgery performed under general anesthesia with tracheal intubation, non-intubated thoracic surgery with sedation and regional anesthesia has been performed recently. Aims and objectives: The aim of this study was to compare postoperative NLR and ΔNLR between intubated and non-intubated patients who underwent lung resection. Methods: This retrospective study included preoperative and postopera­tive data of 60 patients who underwent surgical resection for stage I non-small cell lung cancer. Preoperative and postoperative NLR and ΔNLR were compared between intubated and non-intubated patients during surgery. Results: There was no significant difference in preoperative NLR between two groups. Postoperative NLR (8.5[0.3-10.0] vs 5.3[0.2-8.0], P Conclusions: Postoperative NLR and ΔNLR were significantly lower in non-intubated patients compared with intubated patients during lung resection surgery.
