Insights

Administering an oral isosmolar solution of electrolytes (ISE) can safely interrupt prolonged fasting in pediatric surgical patients. This method reduces gastric volume and maintains safe pH levels without causing hypoglycemia.

Area of Science:

  • Pediatric Anesthesiology
  • Gastroenterology
  • Surgical Patient Management

Background:

  • Prolonged fasting in pediatric surgical patients is necessary but can lead to complications.
  • Optimizing fasting protocols is crucial for patient safety and comfort.
  • Oral isosmolar solutions of electrolytes (ISE) offer a potential method to mitigate fasting-related risks.

Purpose of the Study:

  • To evaluate the safety and efficacy of using an oral isosmolar solution of electrolytes (ISE) to interrupt prolonged fasting in children undergoing elective surgery.
  • To assess the impact of ISE on gastric volume, pH, and blood glucose levels.

Main Methods:

  • A randomized controlled trial involving 40 pediatric patients (3-12 years) undergoing general anesthesia.
  • Patients were assigned to either an overnight fasting group or a group receiving oral ISE 3 hours before fasting completion.
  • Gastric residual volume (RGV), pH, and blood glucose levels (BGL) were measured post-anesthetic induction.

Main Results:

  • Patients receiving oral ISE had significantly lower residual gastric volumes (RGV) compared to the control group.
  • Gastric pH levels were significantly higher in the group that received oral ISE.
  • Blood glucose levels (BGL) remained comparable between both groups, indicating no hypoglycemia.

Conclusions:

  • Interrupting prolonged fasting with oral ISE in pediatric surgical patients is safe and effective.
  • Oral ISE administration leads to a low-risk residual gastric volume and safe pH levels.
  • This intervention does not increase the risk of fasting-induced hypoglycemia in pediatric surgical patients.

Parenteral Anesthetics: Overview01:24

Parenteral Anesthetics: Overview

Intravenous anesthetics are drugs administered parenterally to induce anesthesia or sedation. Propofol is a widely used agent formulated as a 1% emulsion in soybean oil, glycerol, and egg phosphatide. It induces rapid anesthesia primarily due to its rapid distribution from the bloodstream to target tissues and is metabolized in the liver. However, it can cause significant pain on injection and hypertriglyceridemia. Fospropofol, a water-based prodrug of propofol, lacks these adverse effects.
Enteral Nutrition I: Orogastric and Nasogastric Feeding01:26

Enteral Nutrition I: Orogastric and Nasogastric Feeding

Enteral nutrition delivers nutrients directly to the stomach or small intestine through a tube. This method is appropriate for patients who cannot eat but still have a functioning digestive system. It is also beneficial for individuals with swallowing difficulties, anorexia, malabsorption, or those who have undergone gastrointestinal (GI) surgery.
Orogastric (OG) and nasogastric (NG) feeding are two standard methods used for enteral nutrition. Enteral nutrition is often preferred over...

Enteral Nutrition II: Nasointestinal and Gastrostomy Feeding

Enteral nutrition encompasses various methods of delivering nutrition directly to the gastrointestinal (GI) tract, bypassing traditional oral intake. It is particularly beneficial for patients who cannot eat by mouth but have a functioning digestive system. Key methods include nasointestinal feeding, gastrostomy, and jejunostomy, each suited to different clinical scenarios based on the patient's needs and condition.

Parentral Nutrition: Centeral and Peripheral Parental Nutrition

Parenteral Nutrition (PN) delivers essential nutrients directly into the bloodstream, bypassing the digestive system. It is commonly used for individuals with severe digestive disorders or conditions that prevent normal nutrient absorption.
PN can be administered through two primary routes:
1. Central Parenteral Nutrition (CPN):
CPN involves delivering a high concentration of nutrients through a large vein. This is typically achieved using a Peripherally Inserted Central Catheter (PICC) or,...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

Understanding the physiological differences in the pediatric population is crucial for effective pharmacotherapy. Neonates, infants, and children exhibit significant variations in gastric pH, gastric emptying time, intestinal transit time, and biliary function. These variations profoundly affect oral drug absorption, necessitating a nuanced approach to pediatric dosing.Neonates present with a unique physiological profile, having a gastric pH greater than 4 and faster and more irregular gastric...

Peritoneal Dialysis I: Introduction and Procedure

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...
