Summary

One-lung ventilation (OLV) is essential during mediastinal mass excision. However, OLV induces a drastic increase of intrapulmonary shunt due to maintained pulmonary perfusion through the nonventilated lung. In addition, it is reported that supine positioning of patient during OLV, which is required during mediastinal mass excision, results in worse oxygenation than lateral decubitus positioning.

Iloprost is a prostaglandin analogue and when inhaled during OLV, it acts selectively on the pulmonary vasculature, reducing pulmonary vascular resistance of well-ventilated lung and thereby alleviating ventilation-perfusion mismatch. The purpose of this study is to evaluate the effects of inhaled iloprost on oxygenation during one-lung ventilation in patients undergoing mediastinal mass excision.

Conditions

  • Mediastinal Mass

Interventions

DRUG

5ml of inhaled normal saline

After the initiation of OLV, 5ml of normal saline is inhaled for 20 minutes using ultrasonic nebulizer, which is connected to the inspiratory limb of the ventilator system. Arterial blood gas analysis is performed 20 minutes after the completion of drug inhalation.

DRUG

20μg (2ml) of inhaled iloprost (Ventavis®) and 3ml of inhaled normal saline

After the initiation of OLV, mixture of iloprost 2ml and normal saline 3ml is inhaled for 20 minutes using ultrasonic nebulizer, which is connected to the inspiratory limb of the ventilator system. Arterial blood gas analysis is performed 20 minutes after the completion of drug inhalation.
