Summary

To observe the effectiveness of ultrasound-guided alveolar recruitment in thoracic surgery with one-lung ventilation(OLV).

Detailed description

One-lung ventilation(OLV) is essential in thoracic surgery for patient safety and better surgical view. However, pulmonary complications such as hypoxemia may be caused by OLV which might be preventable with adequate alveolar recruitment and positive end-expiratory pressure(PEEP). Alveolar recruitment has been performed with conventional methods without diagnostic tools in clinical setting. Ultrasound is a non-invasive, radiation-free device with high accuracy for the diagnosis of lung atelectasis. There are a few reports regarding the usefulness of lung ultrasound in other surgeries, but not in thoracic surgeries with OLV. Thus, investigators designed a study to observe the effectiveness of ultrasound-guided alveolar recruitment in thoracic surgery with OLV.

Conditions

• One Lung Ventilation

Interventions

Type	Name	Description
PROCEDURE	Lung-sono guided	The patient undergoing thoracic surgery is intubated with double lumen tube after induction of general anesthesia with propofol and remifentanil. In the intervention group, alveolar recruitment is performed to the non-surgical side of lung under examination with ultrasound just after anesthesia induction. During the gradual increment in the pressure of recruitment, the anesthesiologist can find the opening pressure that means the minimal pressure at which observed atelectasis starts to disappear. Then, alveolar recruitment is performed with the opening pressure until the atelectasis is not visible.
