新生儿液体疗法是一门比较精细、要求十分严格的临床应用学科。由于新生儿体液代谢、酸硷平衡方面具有显著的特点,故其液体疗法不同于其他年令时期。本文就新生儿体液生理特点(包括水电解质代谢、酸硷平衡特点),体液紊乱、酸硷失衡临床特点及液体疗法总的原则与要求,进行重点阐述,务求简明扼要。 Neonatal fluid therapy is a more sophisticated and demanding clinical application discipline. Because of neonatal fluid metabolism, acid-base balance has a significant feature, so the liquid therapy is different from other years. This article focuses on physiological characteristics of neonates with body fluids (including water and electrolyte metabolism, pH balance characteristics), body fluid disorders, clinical features of acid-base imbalance and the general principles and requirements of liquid therapy, in order to concisely and concisely.
