Lung Recruitment Maneuvers for Postoperative Atelectasis Prevention After

Status Completed

Clinical Trial Summary

The investigators hypothesized that an ultrasound-guided lung recruitment maneuvers would be more effective in preventing postoperative atelectasis than conventional alveolar recruitment after surgical correction of idiopathic adolescent scoliosis.

Clinical Trial Description

In anesthetized children, the incidence of lung collapse with episodes of hypoxemia is high. Diaphragm dysfunction induced by general anesthesia is one of the most important factors in the genesis of regional losses of lung aeration; the mass of the abdominal organs pushes the diaphragm cranially compressing the lungs in the most dependent areas. Such regional lung collapse may range from slight loss of aeration to complete atelectasis. Scoliosis correction surgery for adolescent idiopathic scoliosis (AIS) is effective in preventing deterioration of lung function caused by disease progression, and improving lung volume over the long term. However, complications of the respiratory system and pulmonary dysfunction may occur in the immediate postoperative period. General anesthesia (GA) and positive pressure ventilation can cause decreased lung volumes, expiratory flow rates, and oxygenation after surgery as a result of positive pressure ventilation, partial recovery of respiratory muscle, pain, and immobilization. Lung ultrasound has been gaining consensus as a noninvasive, radiation-free tool for diagnosing various pulmonary diseases in adult and pediatric patients. Evidence supporting lung ultrasound use is expanding beyond emergency and critical care settings to perioperative care. It has been reported that lung ultrasound (LUS) at a patient's bedside immediately following surgery can be useful for diagnosing respiratory complications. LUS has proven to be a valuable bedside diagnostic tool for pneumothorax, with high sensitivity and specificity (78.6% and 98.4%, respectively), and a higher rate of detecting abnormalities such as lung alveolar consolidation and pleural effusion than bedside chest X-ray or physical examination. LUS has also been used to diagnose anesthesia-induced atelectasis in pediatric patients. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
