Insights

Warming intravenous fluids under a mattress, compared to a fluid warming system, more effectively increased core body temperature in pediatric patients during abdominal surgery. Both methods successfully maintained normothermia.

Area of Science:

  • Pediatric Anesthesiology
  • Surgical Patient Safety
  • Thermoregulation in Children

Background:

  • Maintaining normothermia is critical during pediatric surgery.
  • Intravenous (i.v.) fluid warming is a key strategy for temperature control.
  • Effectiveness of different i.v. fluid warming methods requires evaluation.

Purpose of the Study:

  • To compare two methods of warming i.v. fluids for preserving normothermia in pediatric patients undergoing abdominal surgery.
  • To assess the impact of fluid warming techniques on intraoperative core temperature.

Main Methods:

  • 59 children (≤8 years) undergoing abdominal surgery were randomized into two groups.
  • Group M: i.v. tubing placed under a warming mattress.
  • Group T: active i.v. fluid tube warming system.
  • Core temperature (CT) and infusion fluid temperature (IFT) measured at 30-min intervals.

Main Results:

  • Baseline characteristics (age, weight, procedure length) were similar between groups.
  • IFT increased by 1.2°C in Group M vs. 0.2°C in Group T.
  • Core temperature increased by 1.0°C in Group M vs. 0.2°C in Group T, achieving similar final CTs.
  • Higher CT increase in Group M correlated with higher IFT.

Conclusions:

  • Warming i.v. fluids under a mattress led to a more pronounced increase in core temperature compared to an active warming system.
  • Both warming methods effectively preserved normothermia during pediatric abdominal surgery.
  • The method of warming i.v. fluids can influence intraoperative patient temperature.

Methods of reducing fever

The signs and symptoms of fever include hot and dry skin, flushed face, thirst, muscle aches, anorexia, headache, tachycardia, tachypnea, and fatigue. Elevated body temperature is reduced using two methods: pharmacological and nonpharmacological. Proper identification and treatment of the root cause of a fever is of utmost importance.
Pharmacological Methods of Reducing Fever:
Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia01:16

Local Anesthetics: Clinical Application as Intravenous Regional Anesthesia

Intravenous regional anesthesia or the Bier block technique is used to anesthetize a specific limb or extremity. It uses exsanguinated or blood-drained vessels to transport local anesthetics or LAs to the peripheral nerve trunks. Lidocaine without vasoconstrictors like epinephrine is most commonly used for this technique. Other drugs used are prilocaine, ropivacaine, and chloroprocaine. Bupivacaine is not recommended for this technique due to its high cardiac toxicity.

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,...
