随着儿童外科的发展和围术期管理水平的提高,儿童围术期的液体治疗日益得到重视。儿童由于本身的生理特点,对容量治疗的要求更高,液体管理不当不仅无法改善儿童围术期水电解质、酸碱平衡紊乱,反而会导致儿童围术期并发症的发生。合理的容量治疗策略包括输注适当的液体量及选择合适的液体,从而达到维持有效的循环容量、保障组织代谢及氧供的目的。 With the development of pediatric surgery and perioperative management, perioperative liquid therapy is gaining more and more attention. Children due to their physiological characteristics, the capacity of the higher treatment requirements, improper liquid management not only failed to improve perioperative water and electrolyte, acid-base balance disorders, but will lead to perinatal complications in children. Reasonable volume treatment strategies include infusion of the appropriate amount of fluid and selection of suitable fluids to maintain the effective circulation capacity and to protect the tissue metabolism and oxygen supply.
