Optimal perioperative fluid management is an important component of Enhanced Recovery After Surgery (ERAS) pathways. Fluid management within ERAS should be viewed as a continuum through the preoperative, intraoperative, and postoperative phases. Each phase is important for improving patient outcomes, and suboptimal care in one phase can undermine best practice within the rest of the ERAS pathway. The goal of preoperative fluid management is for the patient to arrive in the operating room in a hydrated and euvolemic state. To achieve this, prolonged fasting is not recommended, and routine mechanical bowel preparation should be avoided. Patients should be encouraged to ingest a clear carbohydrate drink two to three hours before surgery. The goals of intraoperative fluid management are to maintain central euvolemia and to avoid excess salt and water. To achieve this, patients undergoing surgery within an enhanced recovery protocol should have an individualized fluid management plan. As part of this plan, excess crystalloid should be avoided in all patients. For low-risk patients undergoing low-risk surgery, a ''zero-balance'' approach might be sufficient. In addition, for most patients undergoing major surgery, individualized goal-directed fluid therapy (GDFT) is recommended. Ultimately, however, the additional benefit of GDFT should be determined based on surgical and patient risk factors. Postoperatively, once fluid intake is established, intravenous fluid administration can be discontinued and restarted only if clinically indicated. In the absence of other concerns, detrimental postoperative fluid overload is not justified and ''permissive oliguria'' could be tolerated.RĂ©sumĂ© La gestion pĂ©riopĂ©ratoire optimale des liquides est un Ă©lĂ©ment important des programmes de rĂ©cupĂ©ration rapide aprĂšs la chirurgie (RRAC). La gestion des liquides dans le cadre de la RRAC doit ĂȘtre vue comme un continuum au travers des phases prĂ©-, per-et postopĂ©ratoires. Chaque phase est importante pour amĂ©liorer la condition du patient et des soins sous-optimaux au cours d'une de ces phases peuvent miner les meilleures pratiques dĂ©ployĂ©es tout au long de la RRAC. L'objectif de la gestion prĂ©opĂ©ratoire des liquides est de faire en sorte que le patient entre en salle d'opĂ©ration correctement hydratĂ© et dans un Ă©tat euvolĂ©mique. Pour y parvenir, un jeĂ»ne prolongĂ© n'est pas recommandĂ© et le nettoyage mĂ©canique de l'intestin est Ă Ă©viter. Les patients doivent ĂȘtre encouragĂ©s Ă absorber une boisson claire riche en hydrates de carbone, deux Ă trois heures avant la chirurgie. Les buts de la gestion peropĂ©ratoire des liquides sont de maintenir une euvolĂ©mie centrale et d'Ă©viter un excĂšs de sel et d'eau. Pour y parvenir, les patients subissant une intervention chirurgicale dans le cadre d'un protocole de rĂ©cupĂ©ration rapide devraient avoir un programme personnalisĂ© de gestion des liquides. Dans le cadre de ce plan, l'excĂšs de cristalloĂŻdes doit ĂȘtre Ă©vitĂ© chez tous les patients. Pour des patients Ă faible risque subissant une intervention c...
