Utilization of Critical Care U/S Imaging Tools for Assessment of Cardio-pulmonary Complications in Extracorporeal Circulatory Support in Patients Post Cardiac Surgery and ECMO.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Extracorporeal life support (ECLS), including extracorporeal membrane oxygenation (ECMO), is increasingly used in patients post-cardiac surgery. However, cardiopulmonary complications and delayed weaning remain common. Objectives: This study aims to investigate the clinical course of post-cardiac surgery and extracorporeal membrane oxygenation patients using lung ultrasound and echocardiography. Patient and methods: This prospective multicenter observational study was conducted in the intensive care units of King Fahd Military Medical Complex, Saudi Arabia, and Cairo University, Egypt. A total of 103 adult patients requiring ECMO or post-cardiac surgery with cardiopulmonary bypass were enrolled. Result: Postoperative echocardiographic assessment showed significant reductions in EF, TAPSE, and VTI, with increased VTI variability. Extubation time correlated significantly with EF, LVESD, LA diameter, and postoperative VTI variability. Diaphragmatic ultrasound revealed reduced excursion and thickness fraction postoperatively, both strongly associated with prolonged ventilation. LUS detected atelectasis, pleural effusions, and diaphragmatic dysfunction earlier than conventional imaging. Conclusion: CCUS is a valuable bedside tool in post-cardiac surgery and ECMO patients. Echocardiographic parameters (EF, LVESD, and VTI variability) and diaphragmatic function indices are strong predictors of weaning success, while LUS facilitates early pulmonary complication detection. Incorporating CCUS into routine monitoring may enhance patient outcomes and optimize weaning strategies.
