小儿体液学与小儿血液学在一个完整的机体内，是双方密切相关，维护机体生理性内环境的稳定性、生物活性潜能的正常发挥，以及代偿病生理状态侵裘等。小儿体液与小儿血液在各自量方面相互影响着，不同龄别有着年龄上的特点，年龄愈小相对的体液总量愈大，尤其新生儿更较为突出 Pediatric hematology and pediatric hematology in a complete body, are closely related to both to maintain the stability of the physiological environment of the body, the normal development of biological activity potential, as well as compensatory physical conditions such as Qiuqiu. Pediatric fluid and pediatric blood affect each other in their own quantities, different ages have the characteristics of age, the younger the relative volume of fluid, the greater the more prominent neonatal
