Patient received succinylcholine as a muscle relaxant(0.5 mg /kg)for induction of anaesthesia for rigid bronchoscopy.

Patient received rocuronium (0.25 mg/ kg) as muscle relaxant for induction of anaesthesia for rigid bronchoscopy, at the end of procedure rocuronium was reversed with sugammadex (0.5mg/kg.)

Patients received rocuronium (0.25 mg /kg)as muscle relaxant for induction of anaesthesia for rigid bronchoscopy.

Anaesthesia was induced and maintained with propofol (1-2 mg/kg) and remifentanil (0.5 µg/kg). The study arm was immobilized and a dual electrode for peripheral nerve stimulation was placed over the ulnar nerve near the wrist. Neuromuscular monitoring was performed with accelerometry.The patients received succinycholine according to the study group.

scoring system proposed for Good Clinical Research Practice using the following variables: conditions of inserting rigid bronchoscope, vocal cord position, and coughing

Fasciculations were graded by the investigator on the following four-point scale

0 = no fasciculations

1. = mild, fine fasciculations of the eyes, neck, face or fingers, without limb movement
2. = moderate fasciculations occurring at more than two sites, or obvious limb movement
3. = vigorous or severe, sustained and widespread fasciculations in the trunk and limbs

Measurement on an numeric ten point scale, the patients receive a questionaire
