慢性鼻窦炎鼻息肉围手术前期处理对术中出血影响的观察

Study of bleeding during surgery of chronic sinusitis and nasal polyp influenced by preoperative treatment]

OBJECTIVE: To explore the method of reducing bleeding during endoscopic sinus surgery for chronic sinusitis and nasal polyp. METHODS: Bleeding during surgery and the effective rate of two groups patients with chronic sinusitis and nasal polyp were compared (68 cases in group A with preoperative treatment, 30 cases in group B without preoperative treatment). RESULTS: The effective rate between group A(91.2%) and group B (80%) is of significant difference (F = 8.617, P = 0.026); The volume of bleeding during surgery between group A that is (53.2 +/- 41.8) ml and group B that is (97.2 +/- 59.0) ml is of significant difference (F = 27.946, P = 0.002). CONCLUSIONS: Controlling the inflammatory reaction of chronic sinusitis and nasal polyp by preoperative treatment is the most important factor to reduce bleeding while undergoing endoscopic sinus surgery. However, the followings are also important factors to reduce bleeding in endoscopic sinus surgery, such as adequate use of vasoconstrictor in the middle nasal meatus during surgery, the use of deliberate hypotension during surgery, controlling the high risk factors by preoperative treatment and reducing trauma during surgery, etc.
