Management of complications Gastric reflux into the airways: drain the patient's head low, tilt the head to the side, or lie on the side Hemodynamic disorders: Lower or increase blood pressure, arrhythmia, then treat symptomatically Symptoms and causes of Vocal - Gas - Bronchospasm: Provide oxygen, ensure ventilation Vinmec International General Hospital with a system of modern medical facilities, equipment and a team of experts and doctors With many years of experience in medical examination and treatment, patients can rest assured that they will be examined and treated at the Hospital.
