Introduction
The worldwide mortality rate due to pediatric sepsis is approximately 25 million. The cases are children in more than half of the mortalities. This affects children, mostly under five years of age. In studies, it was found that the age of the children suffering from sepsis is 25 months. The mortality rate in children is also dependent on the region. Up to 8% of children in intensive care units of hospitals suffer from pediatric sepsis. As proven by microbiological studies, half of the cases were detected because of bacterial infection.
Pediatric sepsis can be defined as an infection present in response to a systemic inflammatory response. In adults, that definition is changed to a life-threatening organ dysfunction caused by dysregulation of the host response to an infection. This definition is not valid for pediatric patients. It includes early resuscitation of the fluid, obtention of vascular access, collecting blood for culture, initiating broad-spectrum antibiotic therapy, and administration of vasoactive agents in case the shock persists. This is included in sepsis bundles, the completion of which decreases the mortality rate.
What Are the Indications of Food Bolus Therapy in Pediatric Sepsis?
World Health Organization in 1990 recommended performing fluid bolus therapy aggressively, reducing the mortality rate to tenfold. The benefits of fluid bolus therapy include improving cardiac output, delivery of oxygen, and organ perfusion. The response shown by the patient can be variable depending on different individuals.
Fluid bolus therapy is also recommended for patients with abnormal perfusion or hypotension. Tissues with clinical signs of poor perfusion include tachycardia, altered mental status, low urine output, abnormal capillary filling time, flushed skin, and weak pulse. If not access to intensive care, the therapy is recommended only in patients with hypotension or all the above criteria. This therapy was associated with mortality in 48 hours and 1 month of exclusion of any malnutrition or pain in the abdomen. Approximately 0ne third of patients did not meet the 5g/dL change and were diagnosed with malaria. Fluid bolus therapy is not validated due to hemodilution. In case of detection of excess fluid, the theory should be discontinued. The cases include edema, pneumonia, and hepatomegaly.
In short, fluid bolus therapy in pediatric patients is indicated only in hypotension and abnormal perfusion cases. The choice of fluid for initiation of resuscitation is the main point that can affect treatment efficiency.
What Are the Guidelines for Food Bolus Therapy in Pediatrics?
The recent changes and updates of Sepsis survival guidelines have not changed the recommendations for Fluid Bolus Therapy in pediatrics. In cases where no excess fluid is present, the recommendation includes a 20 ml/kg bolus to be resuscitated in the first 15 minutes. In children who are critically ill, the recommendation is to inject 10-20ml crystalloid in 30-60 minutes, especially in treatment for nonacute shock. Studies show that patients receiving .40ml/kg Fluid Blolus therapy have more successful treatment outcomes than patients receiving 20ml/kg Fluid Bolus Therapy.
There are no significant changes or any difference in the efficiency of treatment of children with Food Bolus Therapy who are in depression, intensive care, or receive different fluid types. Fluid Bolus therapy is a concern in children with malaria, dengue fever, and meningitis. Studies do not prove or show reduced mortality in patients with Fluid bolus and Fluid Bolus therapy.
What Is Fluid Restrictive Therapy?
There were concerns regarding the harms caused by fluid Bolus Therapy, so fluid restrictive resuscitation emerged for feasibility and safety. The children who received illness and shock clinically after receiving an FBT of 20 ml/kg subsequently received 10 ml/kg. There was no significant difference observed between the two. The severity lowered in the cases. Studies also suggest that alcohol restriction may reduce FBT practice.
In studies with children on fluid restriction, it is considered feasible to use water restriction and separate The groups. Limiting FBT ensures more safety, but there is still the possibility of an alternative method that positively impacts the efficiency of treatment.
Which Fluid Is to Be Chosen for FBT?
The solution that is used for FBt is made from water and electrolytes. This can be divided into physiological and equal crystals. Physiological saline is chlorinated using Na and Cl. Na is the main cation, and Cl is an anion acting in the human body. The equilibrium crystals are Cl-free and are close to plasma composition in which Cl is replaced by buffer and excreated rapidly or otherwise metabolized. In the case of hyperchloremia, Cl ion is reduced from tubules, which causes vasoconstriction and reduces GFR and urine output.
The Surviving Sepsis Campaign has recommended using balanced crystalloids instead of saline for first-line liquid therapy for pediatric use. European Resuscitation Council has supported this and highly recommended it for all children with circulatory failure. Comparing the lactate ringer solution with equivalent crystalloid and physiological saline, the study showed no significant improvement in the pH and bicarbonate levels in the blood. Studies have shown the use of Plasma Lyte failed in reducing the incidence of kidney injury, any condition requiring kidney treatment, and hyperchloremia. Reduction in death rate was seen in patients with kidney damage and vasopressor requiring after 72 hours of ingesting of crystalloid equivalent.
How Long Should Fluid Bolus Therapy Be Given?
As per the Sepsis Survival Strategy recommendations, fluid intake from about 10-20 ml/kg to almost 40-60 ml/kg, depending on body weight, should be given during the first hour of treatment. There is no scientific evidence supporting that using 2 fluid therapies in children that continue for 10 minutes rather than 20 minutes is clear.
Conclusion
Fluid Bolus Therapy has been recommended as the first line of treatment for the management of children suffering from septic shock. Since there are side effects related to overprocessing liquids and are suggestive to be dangerous, newer fluid-restrictive therapies have emerged with efficient results. Fluid-restrictive resuscitation is at the forefront of the strategies currently being evaluated.
