Early prone positioning associations with gas-exchange indices in children after TOF repair

This retrospective cohort study investigated the associations between early prone positioning and gas-exchange indices at prespecified postoperative time points. The population included children who underwent complete tetralogy of Fallot (TOF) repair and did not have evidence of hemodynamic instability. Specific sample size data were not reported in the available information. No comparator group was explicitly defined in the provided details.

Regarding primary outcomes, the main results regarding specific gas-exchange indices were not reported in the input data. Secondary outcomes related to short-term outcomes and hemodynamic instability were listed but specific numerical findings were not provided. Safety and tolerability data, including adverse events, serious adverse events, discontinuations, and general tolerability, were not reported. Consequently, no specific safety profile can be summarized from the available evidence.

Key limitations include the lack of reported sample size, the absence of a defined comparator, and the lack of reported main results and safety data. The study setting was single-center, and funding or conflicts of interest were not reported. Given the observational nature of the study and the incomplete reporting of critical data points, the evidence is insufficient to determine clinical efficacy or safety. Practice relevance remains unclear due to the lack of reported outcomes and limitations.
