The goal of this prospective, blinded, cross-over design trial including 15 client-owned horses was to evaluate 3 methods of sensory function testing for confirming a successful MNB. Testing was performed bilaterally before sedation, 5 min after sedation, and 15 and 30 min after MNB with 0.5% bupivacaine and involved a needle prick dorsal to each naris, hemostat clamping of each nostril, and gingival algometry (measuring sensitivity to pain). Responses to stimulation were numerically scored and scores were summed up to a total score. Total score increases on the blocked side by\u2009\u2265\u20092 between baseline and 30 min Post MNB recordings signified a successful MNB. Sedation in the preceding 6 h, presence of sino-nasal disease, side of dental pathology, age, butorphanol administration, and detomidine dosing (\u00b5g\/kg\/min) throughout the tooth extraction procedure were recorded. In 73% of horses, MNB was successful. Sedation in the preceding 6 h ( P\u2009=\u2009.732), age ( P\u2009=\u2009.936), side of pathology ( P\u2009=\u2009.516), and sino-nasal disease ( P\u2009=\u2009.769) were not associated with total scores. Detomidine dosage and butorphanol use did not differ between horses in which the MNB was considered successful and for those in which it was not ( P\u2009=\u2009.967 and P\u2009=\u2009.538, respectively). Scores obtained with gingival algometry were less closely associated with total scores (rho\u2009=\u2009.649) than those obtained with needle prick and nostril clamping (rho\u2009=\u2009.819 and .892, respectively). Therefore, needle prick and nostril clamping are considered the more reliable methods for use in clinical practice to determine the success of an MNB.<\/jats:p>","DOI":"10.1177\/08987564231164769","type":"journal-article","created":{"date-parts":[[2023,4,4]],"date-time":"2023-04-04T02:31:03Z","timestamp":1680575463000},"page":"48-54","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["Evaluation
