Oxygen Requirements and Growth Patterns

1.5K
Microorganisms exhibit diverse oxygen requirements and growth patterns driven by their metabolic strategies and environmental adaptations. Oxygen, while essential for many organisms, can also be toxic under certain conditions, shaping how microorganisms grow and survive.Oxygen Requirements of MicroorganismsMicroorganisms are classified based on their ability to use or tolerate oxygen:● Obligate aerobes like Mycobacterium tuberculosis need oxygen for energy production, as it serves as the...

Extracorporeal Removal of Drugs: Hemoperfusion and Hemofiltration

244
Hemoperfusion and hemofiltration are critical techniques in medical treatments to eliminate accumulated drugs, metabolites, and electrolytes from the bloodstream. These methods are particularly vital in cases of accidental poisoning and drug overdose.Hemoperfusion involves passing blood through an adsorbent material to remove unwanted substances. The main adsorbents used in hemoperfusion include activated charcoal and Amberlite resins. Activated charcoal can adsorb both polar and nonpolar...

Extracorporeal Removal of Drugs: Peritoneal Dialysis and Hemodialysis

551
Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...

Additional Routes of Drug Administration01:18

Additional Routes of Drug Administration

5.0K
Choosing the appropriate route of drug administration is significantly influenced by two key factors: the therapeutic objectives and the inherent properties of the drug being used.
Administering drugs via inhalation allows for the direct delivery of gaseous, volatile substances or droplets to different parts of the respiratory tract. One of the advantages of the inhalation route is the rapid absorption of drugs into the circulatory system, which is possible because of the large surface area of...

Routes of Drug Administration: Enteral01:18

Routes of Drug Administration: Enteral

6.7K
Medications can be administered through the enteral route using liquids, capsules, or tablets.
Enteral administration involves drug administration via the mouth in two ways: orally or sublingually.
Unlike sublingually drugs, drugs that are taken orally pass through the gastrointestinal (GI) tract and get metabolized by the liver. Once metabolized, the drug is absorbed into the systemic circulation, reaching different body parts via the bloodstream. However, while passing through the stomach,...

Routes of Drug Administration: Parenteral01:25

Routes of Drug Administration: Parenteral

3.0K
The administration of drugs via parenteral routes allows for direct drug introduction into the systemic circulation, resulting in high bioavailability because the medication bypasses the harsh conditions of the gastrointestinal tract and hepatic metabolism.
The intravenous route (IV) of drug administration can be further categorized into two types. The bolus injection administers the entire dose rapidly, while an intravenous infusion slowly delivers smaller doses steadily.
The IV route is often...

Summary

This study analyzed drug use in patients on extracorporeal membrane oxygenation (ECMO), finding that most common medications lack specific dosing guidance. Evidence-based guidelines are urgently needed for these critical care patients.

Area of Science:

  • Critical Care Medicine
  • Pharmacology
  • Pediatric Research

Background:

  • Extracorporeal membrane oxygenation (ECMO) is a life-support technology used in critically ill patients.
  • Drug administration and dosing in ECMO patients are complex due to altered physiology.
  • Lack of standardized dosing guidelines can lead to suboptimal patient outcomes.

Purpose of the Study:

  • To identify drug administration patterns in all age groups receiving ECMO.
  • To determine which commonly used drugs lack published dosing guidance for ECMO patients.
  • To highlight the need for evidence-based dosing strategies in this population.

Main Methods:

  • Retrospective multicenter database study using TriNetX and Pediatric Health Information Systems.
  • Analysis of drug exposure and days of use across age categories: infants, children, and adults.
  • Literature review of pharmacokinetic and ex vivo studies for the top 50 drugs administered to ECMO patients.

Main Results:

  • 17,909 patients were analyzed (58% infants, 18% children, 24% adults).
  • Top drugs included heparin, furosemide, midazolam, morphine, fentanyl, vancomycin, milrinone, hydrocortisone, epinephrine, and lorazepam.
  • Only 28% of the top 50 drugs had ECMO-specific dosing guidance; sedatives, antimicrobials, and cardiovascular agents were frequently used.

Conclusions:

  • A significant gap exists in evidence-based dosing guidance for commonly administered drugs in ECMO patients.
  • Urgent need for research to establish pharmacokinetic data and dosing recommendations for this vulnerable population.
  • Improved drug dosing strategies are crucial for optimizing treatment and outcomes in ECMO patients.
