Drug Dosing: Infants and Children

1.0K
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

Temperature Measurement Sites

A thermometer measures body temperature. The common sites for measuring body temperature are the oral cavity, axillary region, temporal artery, and skin surface, such as the forehead, abdomen, and axilla. True core body temperature is assessed in the rectum, tympanic membrane, pulmonary artery, esophagus, and urinary bladder.
Oral: When assessing oral temperature, the thermometer tip should be placed under the tongue in the posterior sublingual pocket. It offers accurate readings and can be...

Measuring blood pressure is a fundamental skill in healthcare that aids in diagnosing and monitoring hypertension and other cardiovascular conditions. An aneroid sphygmomanometer, commonly used in clinical settings, offers a manual and precise method for blood pressure measurement. The technique for using this instrument involves specific steps that must be carefully executed to ensure accuracy. The following detailed description outlines a two-step technique for assessing blood pressure using...

Counting is the type of measurement that is free from uncertainty, provided the number of objects being counted does not change during the process. Such measurements result in exact numbers. By counting the eggs in a carton, for instance, one can determine exactly how many eggs are there in the carton. Similarly, the numbers of defined quantities are also exact. For example, 1 foot is exactly 12 inches, 1 inch is exactly 2.54 centimeters, and 1 gram is exactly 0.001 kilograms. Quantities...

Microbial Growth Measurement: Indirect Methods

Estimating microbial growth is essential for understanding population dynamics and environmental adaptations. Indirect methods provide valuable insights by measuring parameters such as turbidity, metabolic activity, and biomass, enabling efficient and reproducible assessments.During exponential growth, microbial cells scatter light proportionally to their biomass, a principle used in turbidity measurements. About one million cells per milliliter produce detectable scattering, which a...

Area of Science:

  • Pediatric Emergency Medicine
  • Clinical Assessment Techniques
  • Patient Safety

Background:

  • Accurate pediatric weight estimation is critical for appropriate medication dosing and resuscitation.
  • Existing methods like the Broselow tape and Advanced Pediatric Life Support (APLS) formula have limitations.
  • A simple, reliable weight estimation technique is needed for emergency settings.

Purpose of the Study:

  • To compare the accuracy of the finger counting method for pediatric weight estimation against other common methods.
  • To evaluate the finger counting method's performance in children aged 1 to 9 years.

Main Methods:

  • Prospective collection of data from 207 children (aged 1-9) in a pediatric emergency department.
  • Comparison of the finger counting method with the Broselow tape, parental estimate, Luscombe formula, and APLS formula using Bland-Altman plots.
  • Analysis of proportions of estimated weights within 10% and 20% of measured weight.

Main Results:

  • The finger counting method demonstrated a mean difference of -1.8 kg and estimated weights within 20% in 87% of children.
  • All methods, except APLS, showed similar proportions of weight estimates within 10%.
  • The finger counting method's accuracy was comparable to the Broselow tape and parental estimates.

Conclusions:

  • The finger counting method is an acceptable and simple alternative for pediatric weight estimation in children aged 1 to 9 years.
  • It is more accurate than the APLS method but may underestimate weight compared to parental estimates and the Luscombe formula.
