Maintenance fluid therapy is challenging in horses that cannot drink or are denied feed and water because of concerns about gastrointestinal tract function and patency. Intravenous fluid delivery to meet water needs based on current recommendations for maintenance requirements were obtained in fed horses and therefore might not apply to horses that are not being fed. This is a critical flaw because of the interdependence between intestinal tract water and extracellular water to support digestion while preserving water balance, a concept explained by the enterosystemic cycle. Because horses drink less when they are not eating and hence have lower water needs than fed horses, maintenance water requirements need to be adjusted accordingly. This article reviews this topic and identifies benefits of adjusting maintenance fluid therapy to meet lower demands from gastrointestinal function, such as reduced volumes, lower cost, avoidance of overhydration.

Abstract Background Infants and neonates are at particular risk of hypoglycemia when suffering from sepsis, asphyxia and hypothermia. A prospective study showed that up to 20% of preterm infants who were ready for discharge were still at risk of hypoglycemia when a feed was delayed. In contrast, surgery and critical illness may cause hyperglycemia. Objectives The aim of this study is to Assessment of glucose containing solutions 2.5 % as a maintenance fluid management intra operative in infants undergoing hernia repair as regard hyperglycemia and hypoglycemia. Patients and Methods The study was conducted on 100 randomly chosen patients aged from 28 days to 1 year, American Society of Anesthesiologists (ASA) class I scheduled for elective open inguinal hernia repair in Ain Shams University Hospitals after approval of the medical ethical committee. They were allocated in two groups of 50 patients each: Ringer lactate Group: patients received ringer lactate as maintenance fluid therapy according to body weight, glucose containing solution: patients received glucose containing solution 2.5% as maintenance fluid therapy according to body weight. Results The results of the study revealed that 12% of patients receiving glucose containing solution 2.5 % had simple hyperglycemia with no hypoglycemic patients recorded while the other group with ringer lactate 2% of patients had simple hyperglycemia and 4% of patients had hypoglycemia . Conclusion The usage of glucose containing solution 2.5% remained controversial, in this study we compared glucose 2.5 % in normal saline 0,9 % to ringer lactate and the results didn’t put a final decision to the usage of glucose containing solutions as The results of the study revealed that 12% of patients receiving glucose containing solution 2.5 % had simple hyperglycemia with no hypoglycemic patients recorded while the other group with ringer lactate 2% of patients had simple hyperglycemia and 4% of patients had hypoglycemia.

ObjectiveTo examine the prevalence of dysnatraemias among children admitted for paediatric surgery before and after a change from hypotonic to isotonic intravenous maintenance fluid therapy.DesignRetrospective consecutive time series intervention study.SettingPaediatric surgery ward at the Children’s Hospital in Lund, during a 7-year period, 2010–2017.PatientsAll children with a blood sodium concentration measurement during the study period were included. Hypotonic maintenance fluid (40 mmol/L NaCl and 20 mmol/L KCl) was used during the first 3 years of the study (646 patients), and isotonic solution (140 mmol/L NaCl and 20 mmol/L KCl) was used during the following period (807 patients).Main outcome measuresPrimary outcomes were sodium concentration and occurrence of hyponatraemia (<135 mmol/L) or hypernatraemia (>145 mmol/L).ResultsOverall, the change from hypotonic to isotonic intravenous maintenance fluid therapy was associated with a decreased prevalence of hyponatraemia from 29% to 22% (adjusted OR 0.65 (0.51–0.82)) without a significantly increased odds for hypernatraemia (from 3.4% to 4.3%, adjusted OR 1.2 (0.71–2.1)). Hyponatraemia <130 mmol/L decreased from 6.2% to 2.6%, and hyponatraemia <125 mmol/L decreased from 2.0% to 0.5%.ConclusionsRoutine use of intravenous isotonic maintenance fluids was associated with lower prevalence of hyponatraemia, although hyponatraemia still occurred in over 20% of patients. We propose that the composition and the volume of administered fluid need to be addressed.

AbstractRecent observations have revealed that otherwise healthy children with acute illnesses are prone to hyponatremia due to increased arginine vasopressin production by non-osmotic stimuli. Concern has recently been raised about the potential for iatrogenic hyponatremia as a result of maintenance fluid therapy for those children. To minimize the risk of development of hospital-acquired hyponatremia in sick children receiving maintenance fluid therapy, the routine practice of administration of hypotonic fluids (e.g., 0.18% NaCl with 4% glucose: Na 31 mEq/L, Cl 31 mEq/L) should be abandoned. Instead, isotonic solution, such as 0.9% NaCl (Na 154 mEq/L, K 0 mEq/L, Cl 154 mEq/L) or Hartmann's solution (Na 130 mEq/L, K 4 mEq/L, Cl 110 mEq/L) should be administered. In addition, it must be noted that close monitoring of the children with daily weights, frequent vitals, strict intake and output measurement, and daily chemistries, especially during the first 72 h of parenteral fluid therapy is essential.
