Introduction
Dogs suffering from compressive myelopathies show differences in the intensity of pain, depending on the location. The aim of the study is to compare the dose of propofol needed for intubation of dogs with cervical syndrome to those needed for dogs with thoracolumbar syndrome.
Materials and methods
In this clinical study that consisted of 41 dogs, ASA 2, 21 with thoracolumbar syndrome and 20 with cervical syndrome, dexmedetomidine 180 μgm- 2 was administered intramuscular for sedation followed by intravenous injection of propofol for anesthesia induction. Anesthesia was maintained with isoflurane in 100% oxygen. Pain scoring was conducted in every dog preanaesthetically using the Glasgow pain scale.
Results
Dogs suffering from cervical syndrome needed a statistically significant higher (p<0.001) dose of propofol for induction (3.1±1.071 mgkg-1 [mean ± standard deviation]) than those suffering from thoracolumbar syndrome (1.7±0.463mgkg-1). Dogs with cervical syndrome had also statistically higher Glasgow Pain Scale score (GPS) (13.2/24) than those with thoracolumbar syndrome (8.4/24) (p<0.001). In addition, there was a positive linear correlation between the intensity of pain (Glasgow pain scale score) and the propofol dose (p<0.001).
Conclusions
Results suggest a positive correlation of pain with the amount of propofol required for intubation. Further studies with larger sample size are warrant.
