[Changes in arterial blood oxygen saturation during fiberoptic bronchoscopy in patients of bronchoscopy department of Emam Khomini hospital using pulse oximetry 2001-2002]

ABSTRACT

Fiberoptic bronchoscopy has profusely been used in many hospitals recently. Generally, hypoxemia is very common with fiberotic bronchoscopy. We studied 188 patients under going bronchoscopy of which 106 were male and 82 were female. Their average age was 52.2 + 17.8 years. Before bronchoscopy, all patients have %Sao2 more than 92% and they were under oxygenation with nasal cannula. %Sao2 was recorded in any segment of airways, BAL and Biopsy. Arterial O2 saturation shortage was significant in Carina- during BAL and Biopsy. Reduction of %Sao2 in female was less than male. In old age patient, reduction of %Sao2 was increased. Hypoxemia is a very common complication during bronchoscopy. Hypoxemia in carina and during BAL and Biopsy is significant. BAL is associated with greater levels of oxygen desaturation than when lavage is not done. Thus we recommend all flexible bronchoscopy patients should have pulse oximetry monitoring
