Respiratory evaluation of the risk for postoperative pulmonary complications in patients who preoperatively consulted pulmonologists: Studying both patients who underwent and who precluded planned surgery.
Respiratory Investigation 2018 November
BACKGROUND: Due to advances in medicine, patients with pulmonary diseases have become candidates for surgery under general anesthesia. They often consult pulmonologists to assess their tolerability for surgery. The purpose of this study was to evaluate the significant characteristics responsible for postoperative pulmonary complications (PPCs) and the preclusion of the planned surgery.
METHODS: The clinical data of 462 consecutive patients who consulted at the Department of Respiratory Medicine before surgery under general anesthesia were used in this study. The relationship between the patient׳s characteristics and their outcomes were analyzed. The patients who were scheduled for lung resection were excluded.
RESULTS: Of the 386 patients who underwent planned surgery, 353 had no PPCs (Group A) and 33 developed PPCs (Group B). Planned surgery under general anesthesia was precluded in 31 patients due to respiratory problems (Group C). The significant predictors for PPCs consisted of a higher age, male gender, asthma, gastrointestinal surgery, cardiovascular surgery and a lower percentage of the predicted forced expiratory volume in 1 second (% predicted FEV1 ). The significant factors associated with the preclusion of planned surgery included interstitial pneumonia (IP), dermatologic surgery and a lower % predicted FEV1 . The predicted probability of PPCs in Group C was significantly higher than that in Group A and lower than that in Group B (all p-values < 0.05).
CONCLUSION: The common clinical finding for predicting PPCs and encouraging the preclusion of the planned surgery under general anesthesia was a lower % predicted FEV1 .
