Recommendations for Operation, Measurement, Reporting and Application of Pediatric Lung Ultrasound: Chinese Experts Consensus

Purpose We described the accuracy of ultrasound in determining the position of bronchial blockers (BBs) in children underwent thoracoscopic surgery. Methods We enrolled 52 children with ASA grade I‐III who received thoracoscopic surgery with placement of BBs. Point‐of‐care ultrasound was performed according to the BLUE protocol. The ultrasound‐guided lung sliding sign and curtain sign were used to assess the position of BBs. The accuracy of ultrasound in evaluating the position of BBs, as well as the accuracy and operating time of sliding sign and curtain sign at each examination point were recorded and compared. Results The accuracy of ultrasound in evaluating the position of BBs was 88% (46/52, 95% CI 0.69–0.97). When using the curtain sign to assess the position of BBs, the accuracy was 90% (94/104, 95% CI 0.78–0.96), which was significantly higher than when using the sliding sign (65% (136/208), 95% CI 0.55–0.74) (p = 0.002). The accuracy of curtain sign at the left mid‐axillary line‐diaphragm and the right mid‐axillary line‐diaphragm was respectively 96% (50/52, 95% CI 0.80–0.99) and 84% (44/52, 95% CI 0.65–0.95), which were higher than that of sliding sign at upper blue points and lower blue points. There was no significant difference in the operating time between two ultrasound signs (the curtain sign, 13.4 ± 8.2 s vs. the lung sliding sign, 16.2 ± 10.0 s, p = 0.065). Conclusion Point‐of‐care ultrasound can effectively assess the position of BBs. The accuracy of using the curtain sign at the mid‐axillary line‐diaphragm is higher than that of using the lung sliding sign at the anterior chest wall.
