Combination of a negative pressure suction device and endoscope can accurately locate the bleeding site of refractory epistaxis

Selective endoscopic coagulation of a nasal bleeding vessel is an effective means of treating epistaxis. Precisely locating the bleeding site(s) is critical.To investigate the utility of combining a negative pressure suction device and endoscope in locating bleeding sites of refractory epistaxis.A total of 116 patients with refractory epistaxis, who underwent systematic endoscopic exploration under local anesthesia in the absence of identifiable sites of bleeding were randomizely divided into two groupsCompared with the CG, there were statistically significant differences in length of hospital stay, rebleeding, and postoperative pain and complications (allCombining a negative pressure suction device and endoscope was a safe and effective technique for accurately locating bleeding sites in patients with refractory epistaxis.
