Left Main Stem Bronchus Compression Occurred in Primary Pulmonary Hypertension Patient: A case report / 대한마취과학회지

Eleven year-old boy was scheduled for right encephalo-duro arterial synangiosis (EDAS). He received left EDAS 4 months ago, and there was no problem during the perioperative period. Mild cardiomegaly was suspected in his preoperative chest PA. After intubaton, we couldn't hear the breathing sound of left chest, and the saturation went down to 95%. There was large opaque hemithorax on emergency chest AP, and on the fiberoptic bronchoscopic examination, left main stem bronchus (LMSB) was observed slit-like appearance. Echocardiography revealed severely dilated right atrium and ventricle. In his chest CT, the LMSB was nearly obliterated. The patient was diagnosed as primary pulmonary hypertension, and received full sedation, controlled ventilation, and NO gas. However, the blood pressure of this patient was not maintained in spite of using high-dose inotropics. He expired two days later and this case warns that suspected mild cardiomegaly might hide more ominous sign of primary pulmonary hypertension.

Administration of Atracurium in a Patient Recovering from Organophosphate Poisoning / 대한마취과학회지

A 67-year-old woman accidentally ingested insecticide 3 months ago and received ventilator care for 1 month. Thereafter, she developed tracheal stenosis combined with a tracheal-esophageal fistula, and she was scheduled to receive a tracheal resection anastomosis. We anesthetized her with atracurium under the monitoring of an accelerograph and she did not represent any prolonged respiratory paralysis postoperatively. We administered atracurium 10 mg twice initially and then gave additional 5 mg boluses when the TOF ratio became greater than 0.5. The total dose of administered atracurium was 40 mg and total duration of anesthesia was 360 minutes. We did not extubate her in the operating room in spite of complete recovery from atracurium to preoperative status because her lung condition was not very good preoperatively and severe necK flexion was done for the anastomosis. In the intensive care unit, the patient's condition progressively deteriorated with the development of adult respiratory distress syndrome and acute renal failure. Despite vigorous organ specific support, she discharged hopelessly 24 days after the operation.
