Anaesthesia for Intra-Laryngeal Laser Surgery

HALAPPA N. KONCHIGERI M.B.B.S.1 and MOHAMED H. SHAKER M.D.1

1 University of Illinois Hospital, Department of Anesthesiology, 840 South Wood Street, Chicago, Illinois, 60612

Thirty patients received general anaesthesia for forty intralaryngeal operations using a laser beam. The essential requirements for the anaesthetic management are:

(1) Anaesthetic agents should be non-flammable.

(2) Small diameter red rubber cuffed tracheal tubes provide maximum working space for the surgeon, facilitate controlled ventilation and minimize the explosion hazard of anaesthetic gases in the vicinity of the laser beam.

(3) Continuous muscle relaxation of head and neck and of laryngeal muscles facilitates the instrumentation and lasing of lesions of vocal cords which are thus rendered fixed and immobile.

Preventive measures must be taken against accidental exposure to the laser beam of normal tissues of the patient and of personnel in the operating room.
