ABSTRACT
La administración de fluidos intravenosos, es uno de los pilares de la reanimación del paciente en shock y su beneficio es mayor cuanto antes se inicie. Los fluidos más utilizados para tal objeto son las soluciones cristaloides (solución salina y Ringer Lactato) y los coloides (albumina, gel, dextrán y almidones). Estudios fisiológicos y clínicos han demostrado que los coloides y los cristaloides tienen diferentes efectos y perfiles de seguridad. Por otra parte, ambos tipos de fluidos administrados en exceso o a destiempo pueden tener efectos perjudiciales. Estudios clínicos recientes parecen coincidir que, en general, los coloides no ofrecen mayor beneficio clínico que los cristaloides y se asocian a mayor tasa de eventos adversos. Por tanto, el presente artículo pretende describir las ventajas y limitaciones de los tipos de soluciones que se utilizan para la reanimación de los pacientes críticos en base a literatura más reciente.
The administration of intravenous fluids, is a mainstay of patient resuscitation in shock and your benefit is greater the earlier it starts. The fluids commonly used for this purpose are crystalloid solutions (saline and Ringer Lactate) and colloids (albumin, gel, dextran and starch). Physiological and clinical studies have shown that colloids and crystalloids have different effects and safety profiles. Moreover, both ty-pes of fluids administered in excess or untimely can have detrimental effects. Recent clinical studies seem to agree that, in general, colloids offer no greater clinical benefit than crystalloids and are associated with increased rate of adverse events. Therefore, this article aims to describe the advantages and limitations of the types of solutions used for resuscitation of critically ill patients based on recent literature.

No presente estudo, foram comparados os efeitos de soluções eletrolíticas contendo diferentes fontes de energia administradas via enteral por sonda naso-esofágica de pequeno calibre em fluxo contínuo sobre o equilíbrio ácido base em equinos. Foram utilizadas seis fêmeas adultas em dois quadrados latinos 6x3 simultâneos em modelo misto. Os animais foram distribuídos em três grupos e submetidos a cada um dos seguintes tratamentos: SEDext - 5g de cloreto de sódio, 0,5g de cloreto de potássio, 0,2g de pidolato de magnésio, 1g de gluconato de cálcio e 10g de dextrose diluídos em 1.000mL de água. Osmolaridade mensurada 228mOsmol L-1; SEMalt - 5g de cloreto de sódio, 0,5g de cloreto de potássio, 0,2g de pidolato de magnésio, 1g de gluconato de cálcio e 10g de maltodextrina diluídos em 1.000mL de água. Osmolaridade mensurada: 181 mOsmol L-1 e SEProp - 5g de cloreto de sódio, 0,5g de cloreto de potássio, 0,2g de pidolato de magnésio e 10g de propionato de cálcio diluídos em 1.000mL de água. Osmolaridade mensurada: 282mOsm L-1. As soluções eletrolíticas foram administradas na dose de 15mL kg-1 h-1, durante 12 horas. Os tratamentos com soluções eletrolíticas enterais contendo dextrose, maltodextrina ou propionato de cálcio não alteraram os valores da hemogasometria.
The present study compared the effects of electrolyte solutions containing different sources of energy that were administrated through enteral route by naso-esophageal probe of small-caliber with continuous flow on the acid base balance in horses. Six adult females were used in two simultaneous 6x3 latin squares mixed model. The animals were divided into three groups and received the following treatments: SEDext - 5g of sodium chloride, 0.5g of potassium chloride, 0.2g of magnesium pidolate, 1g of calcium gluconate and 10g of dextrose diluted in 1.000mL of water. The osmolality measured was of 228mOsmol L-1; SEMalt - 5g of sodium chloride, 0.5g of potassium chloride, 0.2g of magnesium pidolate, 1g of calcium gluconate and 10g of maltodextrin diluted in 1.000mL of water. The osmolality measured was of 181mOsmol L-1 and SEProp - 5g of sodium chloride, 0.5g of potassium chloride, 0.2g of magnesium pidolate, 1g of calcium gluconate and 10g of calcium propionate diluted in 1.000mL of water. The osmolality measured was of 282mOsm L-1. The electrolyte solutions were administered in a dose of 15mL kg-1 h-1 for 12 hours. The treatments with enteral electrolyte solutions containing dextrose, maltodextrin and calcium propionate did not change blood gas analysis values in these animals.
ABSTRACT
ObjectiveTo investigate the current situation of postoperative fluid therapy in general surgery department of grade Ⅲ-A general hospitals in Beijing and Tianjin. Methods Postoperative patients in general surgery department who were fasting for 3 days were retrospectively investigated, and 600 cases were recruited without considering age, gender, denomination of disease and operation type.The general information of patients, laboratory examination before and after operation, postoperative fluid therapy for 3 days, postoperative complications and infusion reaction were collected.Results In total 588 valid cases, the volume of average fluids supplement was (3030±638)ml per day, With the prescribed glucose (142+67)g per day, potassium chloride (59.9±23.9) mmol per day and sodium chloride (179.5±66.7) mmol per day. 85.2 % of total patients received nutrition support and the ratio of parenteral nutrition/enteral nutrition (PN/EN) was 28/1.There were 549 patients with BMI>18.5 before operation, and among them, 470 cases (85.6%)received parenteral and enteral nutrition treatment. There were 39 patients with BMI < 18.5 and 27 cases (69.2%) received parenteral nutrition support without enteral nutrition treatment. During the 3 days after operation, there were 36 cases with fluid therapy without potassium chloride supplement.ConclusionsThe proportions of receiving nutrition support and parenteral nutrition treatment are relatively high in grade Ⅲ-A general hospitals in Beijing and Tianjin. Ready-to-use preparation canreduce mistake and will be benefit to patients.
