Brief Summary:
To investigate the safety and effectiveness of preoperative aerosol inhalation ICG solution for thoracoscopic accurate resection of congenital lung malformations in children
Detailed Description:
Preoperative preparation Preoperative evaluation of pulmonary ventilation function and enhanced CT examination of the lungs were performed Respiratory symptoms should be improved first in case of complicated respiratory infection ICG solution dissolved in 5ml of normal saline dose 05mgkg was inhaled 30 minutes before surgery
Operation method Intraoperative fluorescence thoracoscopic imaging was used and focal resection was performed All patients were placed in lateral decubitus position under general anesthesia and single lung ventilation was selected A low flow rate 1-2 Lmin and low CO2 pressure 4-5 mmHg were maintained in the thorax to establish an artificial pneumothorax The observation hole is in the 7th or 8th intercostal space of the midaxillary line and the two operating holes are in the 4th or 5th intercostal space of the anterior axillary line and the 8th or 9th intercostal space of the posterior axillary line respectively 30 degrees 10 mm fluorescence thoracoscope After entering the chest cavity the fluorescence endoscope was switched to the fluorescence display mode and the fluorescence-stained normal lung tissue and non-stained lesion tissue could be clearly displayed through the display screen and the external boundary of the lesion was marked with an electric hook The mediastinal pleura and pulmonary pleura were opened along the boundary of the lesion and the lung tissue was split along the gap between the lesion and the lung tissue with an electric coagulation hook and an ultrasonic knife and the lesion arteries and bronchi were freed Smaller blood vessels could be cut by Ligasure or ultrasonic knife directly and thicker blood vessels and bronchi should be cut by Hemolock until the lesion resection was completed After the lesion was removed the chest was rinsed with warm normal saline and the lung tissue section was carefully examined to confirm that there was no active bleeding and air leakage and the lung was well dilated The intercostal nerve was blocked under thoracoscopic vision Finally the thoracic closed drainage tube was placed in the midaxillary line puncture hole and the incision was closed
Post-operation follow-up All patients undergo outpatient follow-up 3-6 months after surgery including pulmonary CT and pulmonary ventilation function measurements and comparison of VT tidal volume TiTe suctionexhalation time ratio TPTEFTE peak time ratio and VPEFVE peak volume ratio before and after surgery
