Objective This study aimed to explore the"special"review points and ethical strategies in the ethical review of medical research involving children,providing references for the medical research on this group.Methods Combining the physical and mental characteristics of children,and comparing clinical research ethics review points,this study discussed the key aspects to be concerned about in the ethical review of medical research involving children,and proposed"special protection"strategies to be implemented.Results Ethics committees should fully recognize the uniqueness of child development.The defi-nition of minimal risk in the child population needs to be fully understood at the risk-benefit assessment stage,to develop ethical responses to the risk-benefit ratios in different situations,and to avoid special risks.Informed consent procedures should adhere to basic principles while respecting dissenting voices by designing multiple versions of informed consent for research,and devel-oping informed consent countermeasures for vulnerable children groups.Conclusions Medical research involving children should follow more rigorous and scientific procedures to protect rights,standardize clinical research in pediatric healthcare,and promote the healthy development of pediatric health endeavors.
