Abstract
PURPOSE: Hypoxemia appear as main complication related diagnostic bronchoscopy. Several factors like a technique of bronchoscopy, anesthesia and body position during procedure may increase risk of hypoxemia event. Therefore, there is a need of data to evaluate the related factors.
METHODS: This study is cross sectional with total 195 consecutive patients of suspicion lung malignancy who undergoing bronchoscopy from January until april 2019. All participants have a normal blood gas analysis before procedure then observed for oxygen saturation in 3 phase of premedication, during and post-bronchoscopy. Hypoxemia was defined as an desaturation <90%
with measured by pulse oxymeter.
RESULTS: Total hypoxemia events was 40 cases (20,5%). The most frequent occurrence hypoxemia phase is during
bronchoscopy (20%) with median duration of hypoxemia is 15 seconds. Mostly, hypoxemia appears in early 10 minutes (11,3%) during phase of procedure. The factors like female gender and duration of procedure more than 26 minutes are statiscally
significant with rise of hypoxemia event (p<0,05). Other several factors like transbronchial lung biopsy technique (28,1%), concious sedation (21,4%) and sitting position (36,4%) have higher proportion of hypoxemia although the difference wasn’t
significant (p>0,05).
CONCLUSIONS: This study suggested the factors like gender and time of duration of procedure were related with hypoxemia event in lung tumor cases undergoing diagnostic bronchoscopy. Operator also should pay more attention to rise of hypoxemia especially in early 10 minutes procedure with transbronchial lung biopsy technique, concious sedation and sitting position.
CLINICAL IMPLICATIONS: with these results, we can predict several factors may contribute hypoxemia related bronchoscopy to prevent fatal complication ahead.
DISCLOSURE: No significant relationships
