Howard H. Erickson, DVM, PhD, et al. “Review of Alternative Therapies for EIPH”, Proceedings of the 53rd Annual Convention of the American Association of Equine Practi- Kansas State University, College of Veterinary Medicine Almost 400 Thoroughbred horses that wore nasal strips were evaluated at the Calder Race Course in Florida in 1999-2000. The horses with the strip had a win percentage 3.4% higher than horses that did not wear a strip. Horses wearing a nasal strip also had a 15% decrease in the interval to the next race (23 days) compared with the race-to-race interval before wearing a nasal strip (29 days).

Kansas State University, College of Veterinary Medicine Six thoroughbred horses were exercised on a treadmill at near-maximal running to fatigue under the following conditions: control (C); wearing nasal strips (NS); medicated with furosemide (NS + F); and wearing nasal strips and medicated with furosemide (NS+F). “A very interesting , and novel, finding of the current investigation is that while both FUR and the NS reduced EIPH severity, the NS was equally as effective as FUR during maximal running to fatigue.” Both FUR and NS caused an increased time-to-fatigue. As in previous studies of the nasal strip, VO2 was reduced, probably due to reduction of the O2 cost of breathing. In theory, this additional O2 should be available for distribution within the contracting locomotory muscles, if needed, thereby increasing the time to fatigue.

University of California, Davis, College of Veterinary Medicine 23 thoroughbred racehorses in active training at Golden Gate Fields Racetrack in California were raced with and without FLAIR Equine Nasal Strips. All horses were administe- red furosemide 4 hours before each race. Mean red blood cell count in BAL fluid in horses with severe bleeding was significantly reduced when wearing nasal strips. The mean lymphocyte count was also significantly reduced in BAL fluid of horses when wearing nasal strips.

Michigan State University, College of Veterinary Medicine Six horses were exercised on a treadmill at speeds corresponding to 100 and 120% maximal heart rate with and without application of Flair Strips. Tracheal pressures, airflow, and heart rate were measured. Main effects of the nasal strip were a significant decrease in inspiratory airway resistance and a significantly lower negative peak tracheal inspi- ratory pressure. The researchers stated that nasal strips probably decrease the amount of work required for respiratory muscles in horses during intense exercise and may reduce Geor, Ray J.

Eight thoroughbred horses were exercised at 120% maximal oxygen consumption (VO2max) by sprinting on a high speed treadmill under the following conditions: control (c); wearing FLAIR Equine Nasal Strips (ns); medicated with furosemide (f); wearing FLAIR Equine Nasal Strips and medicated with furosemide (NS+F). Horses treated with furo- semide carried weight equal to that caused by fluid loss after furosemide administration. Horses wearing FLAIR Strips showed a significant reduction of EIPH based on analysis of BAL fluid. Horses injected with furosemide showed a greater reduction in EIPH. Both VO2 and CO2 were significantly lowered in the NS and NS + FR trials over control. The researchers concluded that “the external nasal strip appears to lower the metabolic cost of supramaximal exertion in horses.” “A decrease in the work of breathing during maximal exercise might also be expected to result in a redistribution of blood flow from the respiratory muscles to the muscles of locomotion with a concomitant increase in locomotory muscle VO2.” Kindig, Casey A. PhD et al. “Efficacy of Nasal Strip and Furosemide in Mitigating EIPH in Thoroughbred Horses.” Journal of Applied Physiology. Volume 91: 1396-1400, Kansas State University, College of Veterinary Medicine Five thoroughbred horses were exercised on a high speed treadmill at near maximal efforts four times under the following conditions: control; wearing FLAIR Equine Nasal Strips; medicated with Furosemide; wearing FLAIR Equine Nasal Strips and medicated with Furosemide. Horses wearing FLAIR Strips showed a significant reduction of EIPH based on analysis of BAL fluid. And, although horses injected with furosemide showed a greater reduction in EIPH, there was no further reduction in EIPH when wearing FLAIR and medicated with furosemide.

Volume 20: Number Kansas State University College of Veterinary Medicine Seven horses were exercised on a high speed treadmill with and without FLAIR¨ Equine Nasal Strips. When wearing Nasal Strips V02 was significantly reduced indicating a reduction in the work of breathing. Broncho-alveolar lavage (BAL) fluid analysis also showed a significant reduction in the number of red blood cells recovered from the lungs of horses when wearing the FLAIR Strips as compared to the control run.
