The Practice of Antimicrobial Stewardship in Thoracic Surgery and its Effectiveness.

This study examines the effects of the bundle of antimicrobial stewardship measures for prophylactic antibiotics among thoracic surgery patients. A local protocol, based on current guidelines starting from December 2014, was developed by the Infection Control and Thoracic Surgery Teams. The effects of this protocol were assessed by monitoring a total of 1380 patients before and after its implementation from January 1, 2011, to December 31, 2022.

Immune profiling after minimally invasive lobectomy.

OBJECTIVES: Whether acute phase and immune responses are minimally affected following minimally invasive lung surgery needs further investigation. We performed a pilot study to evaluate the immune profile of patients who underwent video-assisted thoracoscopic surgery or robot-assisted thoracic surgery lobectomies for the treatment of suspicious or known stage I non-small-cell lung cancer. METHODS: Blood samples were taken preoperatively and 3 and 24 h postoperatively were analysed for C-reactive protein, glucose, cortisol, tumour necrosis factor alpha (TNF-α), interleukin 8 (IL-8) and interleukin 10 (IL-10) levels. TNF-α, IL-8 and IL-10 were also measured in lung tissues. T (CD4, CD8), B (CD19) and natural killer (CD56, CD16) cell counts and natural killer cell functions were analysed using a flow cytometry-based assay before and after surgery. RESULTS: Minimally invasive surgery (robot-assisted thoracic surgery + video-assisted thoracoscopic surgery) significantly decreased IL-10 (P = 0.016) levels after surgery. No significant differences were detected in TNF-α (P = 0.48) and IL-8 (P = 0.15) levels before and after surgery. C-reactive protein (P < 0.001), cortisol (P < 0.001) and glucose levels (P < 0.001) increased significantly after surgery. Lymphocyte, total T cell, CD3+CD4+ and CD3+CD8+ CD16+CD56+ cell counts were significantly lower on postoperative day 1. CONCLUSION: There seems to be a dynamic balance between pro- and anti-inflammatory cytokines and immune cells following minimally invasive lobectomy.

Factors affecting mortality in patients with traumatic diaphragmatic injury: An analysis of 92 cases.

BACKGROUND: This study aims to investigate the factors associated with mortality in patients with traumatic diaphragmatic rupture (TDR). METHODS: The records of patients who were operated on at a single hospital with the indication of blunt or penetrating thoracoabdominal injuries between January 2010 and June 2018 and who were perioperatively diagnosed with a diaphragmatic injury were evaluated retrospectively. The details of demographic characteristics, the type and localization of the trauma, presence and number of associated organ injuries, vital signs at admission, time from admission until surgery, type of operation, type of diaphragmatic repair, therapeutic approach, complications and Injury Severity Score (ISS) were analyzed. RESULTS: A total of 92 patients were included in this study. The mortality rate throughout the postoperative period was 15.2%. A penetrating injury was detected in 77.2% of the patients. Associated organ injury was most frequently in the liver, which was significant as a factor that increased mortality (p=0.020). The mortality rate was significantly lower among patients who underwent repair of diaphragmatic rupture when compared with untreated patients (p=0.003). Atelectasis was the most common complication. An ISS ≥24 points in patients with TDR was found to be an independent risk factor associated with mortality (p=0.003). CONCLUSION: Other organs are frequently involved in cases of TDR, and mortality increased significantly in cases with associated liver injury. An ISS of ≥24 was determined to be an independent risk factor associated with mortality. Since the main determinant of mortality was the presence or absence of additional organ injuries, it is important that this should be taken into consideration in these patients.
