Anatomic pulmonary resection via video-assisted thoracic surgery: analysis of 117 cases at a referral center in Brazil

Association of an expanded inflammatory mediators response with clinical and laboratory data in the postoperative period of pulmonary resection: a prospective clinical study

INTRODUCTION

patients undergoing pulmonary resection may experience local or remote complications in the postoperative period due to the inflammatory response, which increases the length of hospital stay and costs. This study objective was to establish an expanded interleukins profile, identifying the main actors in the postoperative inflammatory response, and to correlate them with clinical and laboratory data of patients submitted to pulmonary resection.

METHODS

this was a prospective, interventional, longitudinal study of 27 cases of pulmonary resection performed at HC-UNICAMP, in which we analyzed serum levels of IL 1 α, IL 1 β, IL 1 ra, IL 2, IL 13, IL 6, IL 8, IL 10, IL 12 (p40), IL 12 (p70), IL 17a, TNF α, TNF β, IFN γ, TGF β, MIP 1α, MIP 1β, MCP 1, MCP 3, VEGF, and clinical data before, during, and after surgery.

RESULTS

Individuals had a median age of 63 years, 16 (59%) being male and 11 (41%), female. The clinical factors that influenced inflammatory response were body mass index, smoking, and previous use of corticosteroids, while the influencing laboratory data were the numbers of leukocytes and platelets. Discussion: within this expanded interleukin profile in the inflammatory response of lung resections, our study showed that interleukins IL 6, IL 8, IL 10, IL 1 β, and TNF α should be considered for assessing humoral inflammation.

CONCLUSION

this study can aid in the identification of clinical or pharmacological interventions that modulate the inflammatory response in the perioperative period of pulmonary resections, mitigating local and systemic complications.

Effect of inspiratory muscle training associated or not to physical rehabilitation in preoperative anatomic pulmonary resection: a systematic review and meta-analysis

OBJECTIVE

The aim of this study is to systematically review the effect of inspiratory muscle training (IMT) associated or not with physical rehabilitation in the preoperative period of anatomical pulmonary resection.

METHODS

Search in the databases: MEDLINE, Cochrane CENTRAL, EMBASE, LILACS and PEDro up to November 2019. Randomized clinical trials (RCTs) were included in adults in the preoperative period of pulmonary resection. The selection of studies and data extraction was performed by two independent reviewers. The risk of bias assessed with RoB 2.0 and the quality of evidence with GRADE.

PROSPERO

CRD42018105859.

RESULTS

Six RCTs were included; patients who underwent IMT in the preoperative period showed a significant improvement in functional capacity assessed by the 6-min walk test (6WT) (MD 28,93 [IC 95% 0,28; 57,58], p = 0,04, I² = 0%) and significantly reduced the length of hospital stay (MD -3,63 [IC 95% -4,96; -2,29], p = 0,00, I² = 0%). There was no significant difference between groups regarding pulmonary function, in postoperative complications such as pneumonia (RR 0,56 [IC 95% 0,29; 1,10], p = 0,09, I² = 0%), atelectasis (RR 0,81 [IC 95% 0,24; 2,69], p = 0,72, I² = 0%), mechanical ventilation > 48 h (RR 0,43 [IC 95% 0,12; 1,58], p = 0,20, I² = 0%), in mortality (RR 0,33 [IC 95% 0,04; 3,12], p = 0,33, I² = 0%), and quality of life.

CONCLUSION

IMT associated with physical exercise in the preoperative period of pulmonary resection improves functional capacity and reduces the length of hospital stay in the postoperative period.
