Pharmacokinetics in Pediatric Patients: Drug Excretion01:26

Pharmacokinetics in Pediatric Patients: Drug Excretion

59
In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

Pharmacokinetics in Pediatric Patients: Overview and Drug Absorption

53
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...

Pharmacokinetics in Pediatric Patients: Drug Distribution

75
Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

Pharmacokinetics in Pediatric Patients: Drug Metabolism

51
In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...

Gastrointestinal (GI) diagnostic studies are pivotal in confirming, ruling out, diagnosing, or staging various diseases, including cancers. Following diagnosis, allocating time for discussions with the patient and providing informational resources is crucial. Diagnostic assessments of the GI tract often occur in outpatient settings like endoscopy suites or GI labs. Preparation for these tests may include dietary restrictions, fasting, liquid bowel preparations, laxatives, enemas, and the...

Drug Dosing: Infants and Children

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...

Summary

Naturopathic doctors (NDs) order more laboratory tests than general practitioners (GPs), including more specialized tests. NDs also had fewer abnormal test results compared to GPs.

Area of Science:

  • Integrative medicine
  • Laboratory diagnostics
  • Clinical pathology

Background:

  • Naturopathic medicine focuses on prevention and self-healing using natural therapies.
  • Naturopathic doctors (NDs) utilize clinical laboratory services comparably to traditionally trained physicians.
  • Understanding variations in test ordering between different medical specialities is crucial for effective laboratory stewardship.

Purpose of the Study:

  • To compare the test ordering patterns of Naturopathic Doctors (NDs) with those of General Practitioners (GPs).
  • To identify differences in the types and frequency of laboratory tests ordered by NDs and GPs.
  • To analyze the rates of abnormal test results associated with each provider type.

Main Methods:

  • Retrospective analysis of laboratory test orders from a tertiary pediatric hospital.
  • Comparison of test ordering patterns between NDs and GPs from various pediatric and family medicine clinics.
  • Categorization of test requests into 10 groups to determine ordering frequencies and abnormal result rates.

Main Results:

  • NDs ordered a higher volume of tests per patient compared to GPs.
  • The most frequent tests ordered by NDs included trace elements, toxic metals, and allergens.
  • Tests ordered by NDs showed a significantly lower percentage of abnormal results than those ordered by GPs.

Conclusions:

  • Distinct differences exist in laboratory test ordering patterns between NDs and GPs.
  • NDs tend to order more specialized or 'esoteric' tests.
  • Lower abnormal test result rates in NDs' orders may indicate different diagnostic approaches or patient populations.
