Abstract

A prospective study was performed to detect oxygen saturation (SaO2) during and following fiberoptic bronchoscopy (FOB) in 50 patients. Twenty-five patients (group 1) underwent the procedure without and 25 (group 2) with supplemental oxygen. The SaO2 declined from the baseline value of 96.4% to 92.08% in group 1 and to 94.88% in group 2 after bronchoscopy alone. The decline was also noted when biopsy and broncho-alveolar lavage (BAL) were performed, the lowest values being recorded during BAL. The result showed that the fall in SaO2 in group 2 was significantly less than that in group 1 (P < 0.05). SaO2 returned to baseline values after a mean time of 4.9 minutes in group 1 and 2.4 minutes in group 2, demonstrating the benefit of supplemental oxygen.

摘要

对50例患者进行了一项前瞻性研究，以检测纤维支气管镜检查（FOB）期间及之后的血氧饱和度（SaO2）。25例患者（第1组）在未吸氧的情况下接受该检查，另外25例患者（第2组）在吸氧的情况下接受该检查。仅支气管镜检查后，第1组的SaO2从基线值96.4%降至92.08%，第2组降至94.88%。在进行活检和支气管肺泡灌洗（BAL）时也观察到了下降，BAL期间记录到最低值。结果显示，第2组的SaO2下降明显少于第1组（P < 0.05）。第1组平均在4.9分钟后、第2组平均在2.4分钟后SaO2恢复到基线值，表明吸氧的益处。
