[Meta-analysis of effectiveness evaluation of preventive measures for acute kidney injury in children].

ABSTRACT

Objective: To comprehensively evaluate the effectiveness of preventive measures for acute kidney injury (AKI) in children and identify the effective strategies. Methods: Databases were systematically searched including CNKI, Wanfang, VIP, China Biology Medicine National Knowledge Infrastructure, PubMed, Embase, Cochrane Library databases, and the reference lists of relevant papers for randomized controlled trials on preventing pediatric AKI up to December 2023. Literature screening was conducted based on the inclusion and exclusion criteria, followed by data extraction and quality assessment of included studies. Traditional and network meta-analyses were performed, along with trial sequential analysis (TSA). Results: A total of 21 studies involving 3 483 children were included. Traditional and network meta-analysis showed that dexmedetomidine was effective in preventing AKI in children undergoing cardiac surgery or cardiac angiography (OR=0.26, 0.27; 95%CI 0.11-0.64, 0.13-0.58). Remote ischemic preconditioning (RIPC) was effective in preventing AKI in children after cardiac surgery (OR=0.43, 0.44; 95%CI 0.24-0.79, 0.23-0.83). Traditional and network meta-analysis specific to children with sepsis or septic shock showed that balanced solution was effective in preventing pediatric AKI (OR=0.58, 0.52; 95%CI 0.42-0.79, 0.37-0.73). TSA indicated that the total sample sizes of dexmedetomidine (348 cases) and RIPC (666 cases) both reached the required information size (320 and 534 cases); additionally, the Z-curve for balanced solution (cumulative Z=3.38) crossed the TSA monitoring boundary (Z=3.29). Conclusion: Dexmedetomidine reduces the risk of AKI in children undergoing cardiac surgery or cardiac angiography, RIPC decreases the risk of AKI in children after cardiac surgery, and balanced solution lowers the risk of AKI in children with sepsis or septic shock.
