ABSTRACT
Objective The study discusses the clinical efficacy, surgical technique and new technology application of "⊥" incision in tracheotomy. Methods From March 2014 to December 2015, a total of 300 patients treated in the First Affiliated Hospital of Kunming Medical University with tracheotomy prospective were studied.The statistics of success rate of incision, balloon cuff rupture and complications of "⊥" form incision (groupA) and"I"form incision (group B) during tracheotomy.Result In group A, 144 out of 150 cases (96%) were inserted successfully for the first try,while the first incision was successful in 90/150 cases of group B (60%) (P＜0.01) . Balloon cuff rupture was found in 3/150 cases (2%) in groupA and 15/150 cases (10%) in group B (P＜0.05) . The postoperative complications (postoperative bleeding, subcutaneous emphysema, pneumothorax,laryngotracheal stenosis) were observed in 10/150 cases (6.7%) in groupA and 25/150 cases (16.7%) in group B (P＜0.05).Conclusion The"⊥" tracheal incision is simple, safe and causes fewer complications. It is worthy of generalization and application.
