Comparison of 2 techniques for regional antibiotic delivery to the equine forelimb: intraosseous perfusion vs. intravenous perfusion.

Abstract: The purpose of this study was to compare the synovial fluid concentrations and pharmacokinetics of amikacin in the equine limb distal to the carpus following intraosseous and intravenous regional perfusion. The front limbs of 6 horses were randomly assigned to either intraosseous or intravenous perfusion. A tourniquet was placed distal to each carpus and the limb perfused with 500 mg of amikacin. Systemic blood samples and synovial fluid samples were collected over 70 min from the distal interphalangeal (DIP) joint, metacarpophalangeal joint, and digital flexor sheath. The tourniquet was removed following the 30 min sample collection. The mean peak amikacin concentration for the DIP joint was significantly higher with intravenous perfusion. There were no significant differences in time to peak concentration or elimination half-life between methods at each synovial structure. Each technique produced mean peak concentrations ranging from 5 to 50 times that of recommended peak serum concentrations for therapeutic efficacy.

Summary

This research study investigates two techniques for delivering antibiotics to a horse’s lower front leg: through the bone (intraosseous) and through the vein (intravenous). The study particularly talks about the distribution and action over time of the antibiotic amikacin. The results show that the technique used did not significantly affect the time for the drug to reach its peak concentration or the time it took for half of the drug to be eliminated. However, the antibiotic concentration was significantly higher in the lowermost joint when delivered through the veins.

Assessment of Antibiotic Delivery Methods

  • The study sets out to compare the concentration and pharmacokinetics of an antibiotic called amikacin in the lower leg (distal to the carpus) of horses.
  • The research uses six horses’ front limbs, randomly assigning them to either intraosseous (into the bone) or intravenous (into the vein) perfusion for antibiotic delivery.
  • By using a tourniquet (a compression device) placed below the carpus, the researchers control the dispersal of antibiotic which is introduced in a dose of 500 mg.

Data Collection and Results

  • Systemic blood samples and synovial fluid samples (fluid in the joint spaces) were gathered over a 70-minute interval from the lowermost joint (distal interphalangeal or DIP joint), the metacarpophalangeal joint, and the digital flexor sheath, a fibrous tissue helping in the flexing of the digits.
  • The tourniquet was detached after the sample collection at 30 minutes.
  • The study concluded that the intravenous method resulted in a notably higher mean peak concentration of amikacin in the DIP joint.

Analyzing Time to Peak and Elimination Half-Life

  • Moreover, both methods did not show significant differences in ‘time to peak concentration’ – the time taken for the drug to reach its highest level in the concerned tissues.
  • Neither was there any substantial difference in ‘elimination half-life’, the time required for the concentration of the drug to decrease by half.
  • Both techniques yielded mean peak concentrations that were 5 to 50 times the suggested highest serum concentrations considered effective for therapy, suggesting both methods could potentially deliver therapeutic levels of the drug.
