T Jovaisa, V Vicka, G Linkaitė, J Guseinovaitė, D Ringaitienė, I Norkienė
There is a growing interest in the effects of plasma sodium levels on postoperative outcomes. A trend of using balanced crystalloid solutions is based on the extensive data on chloride and the strong ion difference-related acidosis. However, effects of sodium are often overlooked in this context. The aim of the study was to establish the effects of the routine use of Lactated Ringer’s Solution (RL) on postoperative changes in sodium concentrations and whether these changes result in metabolic acidosis. We performed database analysis of 358 consecutive elective on-pump cardiac surgery cases in a tertiary referral university hospital...

BACKGROUND: Lactate, acetate, and gluconate are anions used in balanced resuscitation fluids, of which lactate and acetate are considered bicarbonate precursors. This study investigated the role of the liver in the ability of balanced and unbalanced solutions to correct acid-base alterations and renal haemodynamics and microvascular oxygenation in a rat model of resuscitated haemorrhagic shock. METHODS: Ringer's lactate, Ringer's acetate, PlasmaLyte, or normal saline were administered following haemorrhagic shock in the presence or absence of a 70% partial liver resection...

OBJECTIVE: Intravenous fluids are broadly categorized into colloids and crystalloids. The aim of this review is to present under a clinical point of view the characteristics of intravenous fluids that make them more or less appropriate either for maintaining hydration when enteral intake is contraindicated or for treating hypovolemia. METHODS: We considered randomized trials and meta-analyses as well as narrative reviews evaluating the effects of colloids or crystalloids in patients with hypovolemia or as maintenance fluids published in the PubMed and Cochrane databases...

BACKGROUND: Glucose requirement in neonates during surgery and the impact of glucose supplementation on neonatal metabolism remain unclear. AIM: This study was designed to identify an appropriate perioperative fluid regimen in neonates which maintains carbohydrate and lipid homeostasis. METHODS: Forty-five neonates undergoing primary repair of a trachea-esophageal fistula were randomly allocated into three groups. During surgery, the neonates received either 1% dextrose in Ringer lactate (RL) (group D1) at 10 ml·kg(-1) ·h(-1) , or 2% dextrose in RL (group D2) at 10 ml·kg(-1) ·h(-1) , or 10% dextrose in N/5 saline at 4 ml·kg(-1) ·h(-1) and replacement fluid with 6 ml·kg(-1) ·h(-1) of RL (group D4)...

BACKGROUND: Renal ischemia-reperfusion injury (IRI) is a common cause of acute kidney injury and a frequent occurrence in critically ill patients. Renal IRI releases proinflammatory cytokines within the kidney that induce crosstalk between the kidney and other organ systems. Atrial natriuretic peptide (ANP) has anti-inflammatory as well as natriuretic effects and serves important functions as a regulator of blood pressure, fluid homeostasis, and inflammation. The objective of the present study was to elucidate whether ANP post-treatment attenuates kidney-lung-heart crosstalk in a rat model of renal IRI...

BACKGROUND: Intravenous fluids are commonly prescribed in childhood. 0.9 % saline is the most-used fluid in pediatrics as resuscitation or maintenance solution. Experimental studies and observations in adults suggest that 0.9 % saline is a poor candidate for fluid resuscitation. Although anesthesiologists, intensive care specialists, perioperative physicians and nephrologists have been the most active in this debate, this issue deserves some physiopathological considerations also among pediatricians...

In preclinical treatment of polytraumatized patients crystalloids are preferentially used. To avoid metabolic acidosis, metabolizable anions like lactate or acetate are used to replace chloride in these solutions. We here studied the effects of malated Ringer's in resuscitation of both shock severities in comparison to lactated and acetated Ringer's. Male Wistar rats underwent severe (mean arterial blood pressure (MAP) of 25-30 mmHg) or moderate (MAP 40-45 mmHg) hemorrhagic shock. Adjacent to the shock period animals were resuscitated with acetated (AR), lactated (LR), or malated Ringer's (MR) and observed for 150 min...

Perioperative fluid therapy is an important component of many medical procedures with animals. Buffered crystalloid solutions avoid inducing metabolic acidosis, but lactated solutions can elevate blood lactate concentrations and acetated solutions have not been thoroughly investigated using large animals. Here, the authors compare blood biochemical parameters in 20 juvenile pigs after perioperative fluid administration of an acetate-buffered solution (Elo-Mel isoton, EMI) or a lactate-buffered solution (lactated Ringer's solution, LRS)...

This study examined the effects of polyethylene oxide (PEO) on the survival rate, hemodynamics, blood gas indexes, lactic acid levels, microcirculation, and inflammatory cytokine levels in rats subjected to severe hemorrhagic shock. The shocked rats were resuscitated with either Ringer's lactate solution or 20 ppm of PEO in Ringer's lactate solution for 1 h. It was found that infusion of PEO effectively improved the survival, metabolic acidosis, oxygen delivery, hyperlactacidemia, tissue perfusion, and inflammatory responses of rats subjected to hemorrhagic shock...

BACKGROUND: Organic acidurias (OAs) are rare inborn errors of metabolism that can present with various neurologic manifestations, propensity for acute metabolic decompensation with anion-gap metabolic acidosis, developmental delay, poor feeding, and failure to thrive. OBJECTIVE: In this case series, we outline the anesthetic management and perioperative outcomes of OA patients. METHODS: We reviewed demographic characteristics, comorbidities, and perioperative course of patients with four different OAs who underwent anesthetic care at our institution between January 1, 2000, and December 31, 2013...

Many situations in clinical practice involving patients with hypovolemia or acutely ill patients usually require the administration of intravenous fluids. Current evidence shows that the use of crystalloids should be considered, since most colloids and human albumin are usually associated with increased adverse effects and high cost, respectively. Among crystalloids, the use of normal saline is implicated with the development of hyperchloremic metabolic acidosis and renal vasoconstriction. These observations have led many authors to propose balanced solutions, mainly Lactated Ringer's, as the infusate of choice...

BACKGROUND: Controlled limb reperfusion has been shown to prevent the deleterious effects of ischemia-reperfusion (IR) syndrome following revascularization of acute limb ischemia (ALI). To reduce the production of cell-toxic oxygen-free radicals, we have established a new initially oxygen-free, hypothermic, heparin-coated perfusion and hemofiltration system and report on our first results. METHODS: In a retrospective single-center study, controlled limb reperfusion was applied in 36 patients (64...

BACKGROUND: Several different crystalloid solutions are available for i.v. fluid administration but there is little information about their specific advantages and disadvantages. METHODS: We performed a systematic search of MEDLINE, EMBASE, and CENTRAL up until May 17, 2012, selecting all prospective human studies that directly compared any near-isotonic crystalloids and reported any outcome. RESULTS: From the 5060 articles retrieved in the search, only 28 met the selection criteria...

BACKGROUND: Metabolic acid-base disorders in critically ill patients may not be identified by base excess (BE) approach. Anion gap method can detect approximately 1/3 hidden "gap acidosis". In such conditions, when adjusted for hypoalbuminemia, Fencl-Stewart's approach can reliably detect the hidden abnormal anions. AIM: Evaluate the efficacy of simplified Fencl-Stewart equation in identifying the changes in acid-base status of sepsis patients following resuscitation with two different fluids...

BACKGROUND: Ongoing improvements in trauma care now recommend earlier use of blood products as part of damage control resuscitation, but generally these products are not available at far forward battlefield locations. For the military, questions continue to arise regarding efficacy of normal saline (NS) vs. lactated Ringer's (LR). Thus, this study compared the effects of LR and NS after severe hemorrhage in pigs. METHODS: 20 anesthetized pigs were randomized into control (n = 6), LR (n = 7), and NS (n = 7) groups...

BACKGROUND: Recently, we have shown that the use of lactated Ringer's (LR) solution is inferior to pure Ringer's solution (RS) in treatment of severe hemorrhagic shock in rats. The present study was performed to evaluate whether this is a specific effect of lactate or also applies to another metabolizable anion, namely acetate. MATERIAL AND METHODS: We subjected male Wistar rats to hemorrhagic shock by dropping the mean arterial blood pressure to 25-30 mm Hg for 60 min, resuscitated with acetated Ringer's (AR) solution, LR solution, RS, or normal saline (NS) within 30 min, and further observed the animals for 180 min...

INTRODUCTION: Although experience within Peru suggests clinical and physiological benefits of treating dehydration caused by diarrhoea with Lactated Ringer's solution (LR) over sodium chloride 0.9%, (NaCl) there is little documented scientific evidence supporting this view. It is important to clarify this issue and determine the best solution for use during epidemics. METHODOLOGY: Forty patients suffering from dehydration due to choleriform diarrhoea were enrolled in the study...

BACKGROUND: In an incidental finding, during a study of plasma chemistry after crystalloid infusion, participants reported subjective cognitive changes, particularly slower thinking, after saline but not Hartmann's (Ringer's lactate) solution. The authors tested the hypothesis that saline infusion would produce greater adverse cognitive changes than Plasmalyte infusion. METHODS: The authors conducted a randomized, cross-over, multiple blinded study of healthy adult volunteers...
