Objective To research the value of bed fiber bronchial microscope technology ha neurosurgical ICU. Methods 28 cases in neurosuxgical ICU who had received bed fiber bronchial microscope operations,including blood and vomit aspiration, bronchoalveolar lavage, sputum bolt clearance were retrospectively analyzed. Results 4 cases of blood and vomit aspiration was cleaned ha time,improvement of respiratory function,31 cases was sputum as- piration by bed fiber bronchial microscope and bronchoalveolax lavage, 31 cases was sputum collected by fiber bronchial microscope and positive rate is 100% ,4 cases of atelectasis was lung recruitment by fiber bronchial micro- scope sputum aspiration. Conclusion Bed fiber bronchial microscope technology can eliminate waste effectivdy, clean dust,there axe great value in treatment of neurosurgical ICU patients with respiratory diseases.
