STUDY DESIGN Prospective case series. ANIMALS 157 dogs undergoing cervical or thoracolumbar spinal surgery. METHODS Data were collected sequentially on canine cases presented from the Neurology Section of the North Carolina State University Veterinary Teaching Hospital for anesthesia and surgery for cervical spinal cord disease. Simultaneously, data were collected on all thoracolumbar spinal surgery cases during the same time period. Data included signalment, drugs administered, surgical approach, disease process, cardiac arrhythmias during anesthesia, and outcome. RESULTS Data were collected from 164 surgical events in 157 dogs. There were 52 cervical approaches; four dorsal and 48 ventral. All thoracolumbar surgeries were approached dorsolaterally. Four dogs 4/52 (7.6%) undergoing a cervical approach did not survive to discharge. Two dogs (2/8; 25%) underwent atlanto-axial (AA) stabilization and suffered cardiovascular arrest and two dogs (2/38; 5.2%) undergoing cervical ventral slot procedures were euthanized following anesthesia and surgery due to signs of aspiration pneumonia. All dogs undergoing thoracolumbar surgery survived until discharge (112/112). Mortality in dogs undergoing cervical spinal surgery was greater compared with dogs undergoing thoracolumbar spinal surgery (p = 0.009), however, in dogs undergoing decompressive disc surgery, intraoperative death rates were not different between dogs undergoing a cervical compared with thoracolumbar approaches (p = 0.32) nor was there a significant difference in overall mortality (p = 0.07). CONCLUSION AND CLINICAL RELEVANCE Overall, dogs undergoing cervical spinal surgery were less likely to survive until discharge compared with dogs undergoing thoracolumbar spinal surgery. Mortality in dogs undergoing cervical intervertebral disc decompression surgery was no different than for dogs undergoing thoracolumbar intervertebral disc decompression surgery. However, dogs undergoing cervical intervertebral disc decompression surgery should be considered at risk for aspiration pneumonia.}, number={2}, journal={VETERINARY ANAESTHESIA AND ANALGESIA}, author={Posner, Lysa P. and Mariani, Christopher L. and Swanson, Cliff and Asakawa, Makoto and Campbell, Nigel and King, Adam S.}, year={2014}, month={Mar}, pages={137–144} } @article{conner_hanel_hansen_motsinger-reif_asakawa_swanson_2012, title={Effects of acepromazine maleate on platelet function assessed by use of adenosine diphosphate activated- and arachidonic acid-activated modified thromboelastography in healthy dogs}, volume={73}, ISSN={["1943-5681"]}, DOI={10.2460/ajvr.73.5.595}, abstractNote={Abstract}, number={5}, journal={AMERICAN JOURNAL OF VETERINARY RESEARCH}, author={Conner, Bobbi J. and Hanel, Rita M. and Hansen, Bernard D. and Motsinger-Reif, Alison A. and Asakawa, Makoto and Swanson, Clifford R.}, year={2012}, month={May}, pages={595–601} } @article{posner_asakawa_erb_2008, title={Use of propofol for anesthesia in cats with primary hepatic lipidosis: 44 cases (1995-2004)}, volume={232}, ISSN={["1943-569X"]}, DOI={10.2460/javma.232.12.1841}, abstractNote={Abstract}, number={12}, journal={JAVMA-JOURNAL OF THE AMERICAN VETERINARY MEDICAL ASSOCIATION}, author={Posner, Lysa P. and Asakawa, Makoto and Erb, Hollis N.}, year={2008}, month={Jun}, pages={1841–1843} } @article{asakawa_ludders_badgley_erb_gleed_posner_2007, title={Effects of adenosine infusion on the minimum alveolar concentration of isoflurane in dogs}, volume={34}, ISSN={["1467-2995"]}, DOI={10.1111/j.1467-2995.2006.00286.x}, abstractNote={OBJECTIVE To determine the effects of adenosine infusion on the minimum alveolar concentration (MAC) of isoflurane in dogs. STUDY DESIGN Prospective, randomized crossover study. ANIMALS Seven adult male and female Beagles weighing 10.9 (7.5, 13.6) kg [median (minimum, maximum)]. METHODS Each dog was anesthetized with isoflurane in oxygen and randomly assigned to receive either an intravenous (IV) adenosine (0.3 mg kg(-1) minute(-1)) or saline (6 mL kg(-1) hour(-1) IV) infusion. After an interval of 7 days or more, each dog was re-anesthetized and treated with the alternative infusion. Using a tail-clamp technique, MAC was determined before (pre-infusion), during (infusion), and 2 hours after the infusions (post-infusion). RESULTS The pre-infusion MAC of isoflurane was 1.25 (1.15, 1.35) [median (minimum, maximum)] vol.% for the saline treatment group and 1.25 (1.05, 1.45) vol.% for the adenosine treatment group, and did not differ significantly between the two treatments. The infusion MAC values were not significantly different (p = 0.16) and were 1.25 (0.95, 1.35) vol.% and 1.05 (1.00, 1.25) vol.%, respectively. The post-infusion MAC values differed significantly (p = 0.016); MAC was 1.15 (1.15, 1.35) vol.% and 1.05 (1.05, 1.25) vol.% for the saline and adenosine treatment groups, respectively. During infusion, mean arterial blood pressure decreased significantly (p = 0.008) during adenosine treatment compared with the saline 66 mmHg (52, 72) and 91 mmHg (68, 110), respectively. End-tidal CO2 (Pe'CO2), urine production, hematocrit, and plasma total solids did not differ significantly between the two treatments at any time (all p > 0.05). CONCLUSION Although the MAC of isoflurane in dogs was not decreased significantly during infusion with adenosine (0.3 mg kg(-1) minute(-1)), it was significantly decreased post-infusion, but only by 0.1 vol.%, an amount not considered clinically important. Adenosine infusion decreased mean arterial pressure by 27% and did not adversely affect renal function.}, number={1}, journal={VETERINARY ANAESTHESIA AND ANALGESIA}, author={Asakawa, Makoto and Ludders, John W. and Badgley, Britton L. and Erb, Hollis N. and Gleed, Robin D. and Posner, Lysa P.}, year={2007}, month={Jan}, pages={9–14} }
