Clinical observation of the treatment of argon knife combined with electric trap in painless anesthesia in senile advanced lung cancer

Objective Effect of electric trap combined with argon plasma coagulation in the treatment of elderly patients with central advanced lung cancer. Methods From July 2014 to August 2017, 68 elderly patients with advanced lung cancer admitted to the Second Hospital of Lianyungang were selected. Under painless anesthesia, all patients were treated by bronchoscopy combined with electric snare and argon knife coagulation. When the argon knife was applied, the airflow velocity was adjusted to be 0.3~2.0 L/min, the output power was 20~40 W, and the catheter was about 1 cm above the lesion. During the application of high-frequency electrotome, the electrocoagulation probe should directly contact the lesion for burning. The treatment time is generally 0.5~2.0 h each time, and the treatment interval is 3~5 d each time. Results 68 patients were treated for 135 times with electric entrap and argon knife, generally 1~4 times for each patient, and one patient was treated 8 times at most. The immediate clinical effect at the end of treatment: 38 cases (55.9%) were completely effective, 23 cases (33.8%) were partially effective, 7 cases (10.3%) were mildly effective, and the immediate effective rate was 100%. There were no serious complications such as hemorrhage and perforation in patients during and after operation. Conclusion The treatment of argon knife combined with electric trap in painless anesthesia is effective in the senile advanced lung cancer, the patients have good tolerance, strong maneuverability, excellent curative effect, can obviously alleviate symptoms, worthy of reference and clinical promotion.
