ABSTRACT
AIM: Ventilator-associated pneumonia (VAP) is the most common intensive care unit (ICU)-acquired infection. The current study aimed to assess the efficacy of mechanical insufflation-exsufflation (MI-E) in preventing VAP in critically ill patients. MATERIALS AND METHODS: This retrospective cohort study was conducted at the ICU of Chiba University Hospital between January 2014 and September 2017. The inclusion criteria were patients who required invasive mechanical ventilation ≥48 hours and those who underwent rehabilitation, including chest physical therapy (CPT). In 2015, the study institution started the use of MI-E in patients with impaired cough reflex. From January to December 2014, patients undergoing CPT were classified under the historical control group, and those who received treatment using MI-E from January 2015 to September 2017 were included in the intervention group. The patients received treatment using MI-E via the endotracheal or tracheostomy tube, with insufflation-exsufflation pressure of 15-40 cm H2O. The treatment frequency was one to three sessions daily, and a physical therapist who is experienced in using MI-E facilitated the treatment. RESULTS: From January 2015 to September 2017, 11 patients received treatment using MI-E. Of the 169 patients screened in 2014, 19 underwent CPT. The incidence of VAP was significantly different between the CPT and MI-E groups (84.2% [16/19] vs 26.4% [3/11], p = 0.011). After adjusting for covariates, a multivariate logistic regression analysis was performed, and results showed that the covariates were not associated with the incidence of VAP. CONCLUSION: This retrospective cohort study suggests that the use of MI-E in critically ill patients is independently associated with a reduced incidence of VAP. CLINICAL SIGNIFICANCE: Assessing the efficacy of MI-E to prevent VAP. HOW TO CITE THIS ARTICLE: Kuroiwa R, Tateishi Y, Oshima T, Inagaki T, Furukawa S, Takemura R, et al.

ABSTRACT
OBJECTIVE: The purpose of this study was to investigate the impact of pulmonary rehabilitation on surgical morbidity and lung function in lung cancer patients with chronic obstructive pulmonary disease (COPD). METHODS: Prospectively, 22 lung cancer patients with COPD who underwent lobectomy between 2000 and 2003 were enrolled for this study as a rehabilitation group (Rehab. Group). The criteria of COPD were preoperative forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC) < or =70% and more than 50% of low attenuation area in a computed tomography. Preoperatively patients performed aggressive pulmonary exercise for two weeks and received chest physiotherapy postoperatively. As a historical control, 60 patients with lung cancer who fulfilled the same criteria but did not receive rehabilitation between 1995 and 1999 (control group) were entered in this study. RESULTS: Patient backgrounds were all equivalent between the two groups. However, FEV1 and FEV1/FVC were significantly lower in the Rehab. Group (p < 0.05). Prolonged oxygen supplement and tracheostomy tended to be more frequent in the control group. The ratio of actual postoperative to predicted postoperative FEV1 was significantly better in the Rehab. Group (p = 0.047). Furthermore, postoperative hospital stay was significantly longer in the control group (p = 0.0003). CONCLUSION: Despite lower FEV1 and FEV1/FVC in the Rehab. Group, postoperative pulmonary complications and long hospital stay could be effectively prevented and FEV1 was well preserved by rehabilitation and physiotherapy.
