Ultrasound-guided lung recruitment maneuver in pediatric acute respiratory distress syndrome
Abstract
1. To investigate the application of bedside ultrasound in guiding lung recruitment maneuvers (RM) in pediatric acute respiratory distress syndrome (PARDS). 2. To compare the efficacy of bedside ultrasound-guided lung RM (US) with that of maximal oxygen-guided lung RM (OXY) in the management of PARDS. Prospective interventional trial, Single arm test.This study involved a cohort of 24 pediatric patients in the Pediatric Intensive Care Unit (PICU) at Shiyan Taihe Hospital from January 2018 to December 2024, The participants, with an average age of 36.79 ± 38.72 months, comprised 14 males and 10 females, all of whom met the diagnostic criteria for pediatric acute respiratory distress syndrome and underwent invasive mechanical ventilation. Lung recruitment therapy was implemented following the protocol established by Wolf GK, which is structured into two distinct phases: the baseline segment, and the recruitment segment. Lung ultrasonography and arterial blood gas analyses were conducted at three intervals—prior to, during, and following the recruitment process for each child. An ultrasound reaeration score (URS) was calculated, and each child was required to satisfy two consecutive recruitment criteria. Key parameters, including opening pressure, ultrasound reaeration score, partial pressure of oxygen (PaO2), partial pressure of carbon dioxide(PaCO2),and dynamic compliance (Cdyn) were recorded for both lung ultrasound-guided recruitment and maximal oxygenation-guided…
How strong is the evidence?
Evidence Hub reads this as a clinical trial, done in people. Its evidence level is 3 of 5 (Moderate · trial / cohort / secondary analysis). Trials without a large randomized design, cohorts and secondary analyses give moderate evidence. Reported size: 24 participants or records.
