Plain-English summary
A review of studies found that dexmedetomidine, a sedative used in dog anesthesia, likely provides better sedation and pain relief compared to other medications like acepromazine and ketamine. While it can lower heart rate and raise blood pressure shortly after administration, the overall safety profile is similar to other premedications. This means that while it has some effects on the heart, it is still considered safe for use in dogs undergoing anesthesia. Many veterinarians may choose dexmedetomidine for its effectiveness in keeping dogs calm and comfortable during procedures.

Abstract
Dexmedetomidine is commonly used in small animal anesthesia for its potent sedative and analgesic properties; however, concerns regarding its cardiovascular effects prevent its full adoption into veterinary clinical practice. This meta-analysis was to determine the effects of dexmedetomidine on sedation, analgesia, cardiovascular and adverse reactions in dogs compared to other premedications. Following the study protocol based on the Cochrane Review Methods, thirteen studies were included in this meta-analysis ultimately, involving a total of 576 dogs. Dexmedetomidine administration probably improved in sedation and analgesia in comparison to acepromazine, ketamine and lidocaine (MD: 1.96, 95% CI: [-0.08, 4.00], <i>p</i> = 0.06; MD: -0.95, 95% CI: [-1.52, -0.37] <i>p</i> = 0.001; respectively). Hemodynamic outcomes showed that dogs probably experienced lower heart rate and higher systolic arterial blood pressure and mean arterial blood pressure with dexmedetomidine at 30 min after premedication (MD: -13.25, 95% CI: [-19.67, -6.81], <i>p</i> < 0.0001; MD: 7.78, 95% CI: [1.83, 13.74], <i>p</i> = 0.01; MD: 8.32, 95% CI: [3.95, 12.70], <i>p</i> = 0.0002; respectively). The incidence of adverse effects was comparable between dexmedetomidine and other premedications (RR = 0.86, 95% CI [0.58, 1.29], <i>p</i> = 0.47). In summary, dexmedetomidine provides satisfactory sedative and analgesic effects, and its safety is proved despite its significant hemodynamic effects as part of balanced anesthesia of dogs.
