Arthroscopic surgery using radio-frequency electrocautery

Cost-benefit comparison: holmium laser versus electrocautery in arthroscopic acromioplasty.

This prospective study was designed to measure the costs and benefits of using a laser rather than electrocautery for soft tissue resection during arthroscopic shoulder decompression. Forty-nine shoulders with refractory Neer stage II impingement (persistent fibrosis and tendinitis) were divided into 2 groups. The composition of the 2 groups was similar with regard to sex, worker's compensation...

Endobronchial Electrocautery Using Snare

Between May 1987 and March 1994, upper airway and tracheobronchial electrosurgery with snare was performed in 13 patients (10 men and 3 women), ranging in age from 18 to 87 years. Four patients had benign lesions, and nine had malignant tumors. Total eradication has been achieved in the two patients with benign lesions. Electroexcision of the endobronchial portion of the tumor helped to clear t...

Electrocautery-induced pacemaker malfunction during surgery.

We report a case of electrocautery-induced pacemaker failure that resulted in asystole in a 15-year-old girl scheduled for cardiac surgery. Her pacemaker was converted to the asynchronous mode the night before surgery. Electromagnetic interference from the unipolar electrocautery caused a reduction in the battery voltage, which allowed the digital circuitry, but not the voltage control oscillat...

Radio-frequency ablation of arrhythmias following congenital heart surgery.

BACKGROUND Cardiac arrhythmias as a late complication following congenital heart surgery are encountered more and more frequently in clinical practice. The use of new electrophysiological methods of visualisation and mapping improves the efficacy of radio-frequency (RF) ablation of these arrhythmias. AIM To assess patterns of atrial arrhythmias following congenital heart surgery and to examin...
