Hypoxemia Event and Related Factor on Diagnostic Bronchoscopy for Lung Tumor Case

Backgrounds: Bronchoscopy is a commonly medical procedure perfomed for diagnose lung tumor cases. Hypoxemia often appear as complication related diagnostic bronchoscopy. Therefore, there is a need of research data to knowing related factors and clinical consequences may occur ahead. Methods: Design of this study is cross sectional with suspicion lung malignancy population who undergoing diagnostic bronchoscopy from January until april 2019 at National Respiratory Center Persahabatan General Hospital Jakarta. Total 195 consecutive patients participated dan observed for oxygen saturation in premedication, during and post-bronchoscopy. Hypoxemia was defined as a desaturation <90% and reviewed several related factor and clinical consequences may appear Results: Total hypoxemia events on diagnostic bronchoscopy was 40 cases (20.5%). The most frequent occurrence hypoxemia time is during bronchoscopy (20%) with median duration of hypoxemia is 15 seconds. The proportion of time appears hypoxemia is commonly in first 10 minutes’ bronchoscopy (11.3%). Demographic factors like gender (P=0.04) and smoking history (P=0.005) are statistically significant with hypoxemia events. Other factors may have relation dan statiscally significant are duration of procedure and procedure with complication (<0.05). Total 5 cases observed in intensive care unit after procedure and no death event have reported in this study Conclusions: This study suggested gender, smoking history, duration of procedure and procedure with complication were related factors with hypoxemic events in lung tumor cases undergoing diagnostic bronchoscopy. Hypoxemia related diagnostic bronchoscopy in this study was not rise into fatal event.
