The patient, a 60-year-old male, who had history of bronchial asthma was admitted for gastrectomy with a diagnosis of gastric perforation. Atropine sulphate (0.25 mg) was administered intravenously for premedication.
Anesthesia was induced with thiopental 300 mg and maintained with nitrous oxide, oxygen and fluothane (0.5 per cent) in a semiclosed system. Forty miligram of succinylcholine was administered prior to tracheal intubation. Twenty miligram of succinylcholine and 28 mg of mylaxen was used for muscle relaxation.
The patient's lungs became slight difficult to ventilate 45 minutes after starting of the operation. Wheezing appeared in both lung fields, but neither secretions nor any anatomicall abnormalities were seen.
It was diagnosed as bronchospam. Anesthesia was persisted in this manner until the end of the operation. Immediatly after the surgery 250 mg of neophylline was administered intravenously, the wheezings disappeared and the patient's lungs became clear.
