description This study aims to evaluate blood pressure measurements in immobilized free-ranging gray wolves (Canis lupus) in Sweden. Eight immobilized wolves (five adults and three juveniles) were included in this study. All wolves were darted from a helicopter with darts containing 250 milligrams of tiletamine and 250 milligrams of zolazepam. Immobilized wolves that showed signs of arousal, recieved a supplemental intramuscular injection of medetomidine. Systolic and diastolic blood pressure was measured non-invasively with an oscillometric device (Memoprint®, MediVet, Babenhausen, Germany) designed for dogs and cats. Rectal temperature, heart rate and respiratory rate were also measured. The hypothesis is that the wolves develop hypertension as a result of helicopter pursuit and the drug used. Three wolves were normotensive, four wolves had a moderate diastolic hypertenstion at one or more measuring point, and one wolf had a severe diastolic hypertension together with a mild systolic hypertension. None of the wolves had a moderate or a severe systolic hypertension. In conclusion, the effect on blood pressure was not as severe as previously thought. It was also noted that wolves who recieved an injection of medetomidine had a better anesthesia. In addition to this, other reference values for blood pressure and heart rates for free-ranging gray wolves should be used in future studies.

Studien avsåg att utvärdera blodtrycket hos immobiliserade frilevande vargar (Canis lupus) i Sverige. Hypotesen är att de sövda vargarna får hypertension av helikopterjakten och tiletamin. Åtta vargar (fem vuxna och tre valpar) ingick i studien. Vargarna sövdes från helikopter med bedövningspilar innehållande 250 mg tiletamin och 250 mg zolazepam, motsvarande 10,6 – 21,3 mg/kg. De vargar som under sövningen uppvisade tecken på att vakna, fick en intramuskulär injektion medetomidin motsvarande doser på 0,016 – 0,0625 mg/kg. Systoliskt och diastoliskt blodtryck mättes icke-invasivt med en oscillometrisk apparat (Memoprint, MedVet, Babenhausen, Tyskland). Rektaltemperatur, hjärtfrekvens och andningsfrekvens mättes var femtonde minut, i direkt anslutning till blodtrycksmätningen. Tre vargar var normotensiva, fyra hade måttlig diastolisk hypertension vid ett eller flera mätningstillfällen, och en varg hade kraftig diastolisk hypertension tillsammans med lindrig systolisk hypertension. Ingen av vargarna hade måttlig eller kraftig systolisk hypertension vid mättillfällena. De vargar som fick medetomidin under anestesin fick en blodtryckssänkning och en lägre andningsfrekvens. Eftersom tidpunkt för första mätning varierade mellan individerna, samt att den aldrig utfördes tidigare än 15 minuter efter pilskott, kan en möjlig initial hypertension ha inträffat. En etablering av referensvärden för blodtryck och hjärtfrekvens hos sövd frilevande varg är nödvändig i framtida studier. 2007-10-30 Other NonPeerReviewed application/pdf sv https://stud.epsilon.slu.se/11718/1/malmsten_j_171123.pdf Malmsten, Jonas, 2007.
