AI Article Synopsis

  • The study aimed to evaluate the sedative and physiological effects of trazodone and gabapentin in cats, using a randomized, placebo-controlled design.
  • The research included 8 healthy adult cats receiving single doses of either drug separately or in combination.
  • Results showed that combining trazodone and gabapentin enhanced sedation and affected heart and respiratory rates, with mild side effects like short-duration excitatory reactions in some cats.

Article Abstract

Despite the increasing use of drugs to facilitate feline management in veterinary care, there is still a lack of information on the anxiolytic and sedative effects and their specific physiological impacts. We aimed to compare the sedative, hematological, biochemical and cardiovascular effects of oral single-dose trazodone and gabapentin, alone or in combination, in 8 healthy adult mixed-breed domestic cats on a prospective, randomized, cross-over, and placebo-controlled study. Cats were assigned to receive an oral single dose of trazodone (50 mg) (TG), gabapentin (100 mg) (GG), trazodone (50 mg) and gabapentin (100 mg) (GTG), or placebo (PG). Sedation score, physiological, hematological, biochemical, and cardiovascular variables were assessed at baseline and 120 minutes after drug administration. The mean dose of trazodone was 12.1± 1.1 mg/kg and gabapentin 24.2± 2.3 mg/kg. All data were normally distributed. Blood tests remained within the reference range, but plasma protein increased by 3.78% in TG. Trazodone alone and associated with gabapentin significantly reduced respiratory rate and systolic blood pressure compared to baseline and placebo. GTG showed a reduction in heart rate and the highest sedation scores. Short-duration excitatory reactions were observed in 37.5% of the cats in GTG and 12.5% in TG. Isovolumetric relaxation time (IVRT) increased in GTG and differed statistically from GG. On ECG, no clinically relevant changes were observed. The association of trazodone (50 mg/cat) and gabapentin (100 mg/cat) increases sedation scores compared to gabapentin alone, with a mild impact on HR, RR, BP, and IVRT in cats.

Background: Postoperative pain usually occur in patients who have undergone functional endoscopic sinus surgery (FESS). Remimazolam and dexmedetomidine could enhance the quality of recovery (QoR) after surgery. The aim of this study was to compare the effects of remimazolam and dexmedetomidine with respect to the QoR-40 score of patients who have undergone FESS.

Background: Unmet caries treatment needs are prevalent among people with disability, partly due to difficulties of cooperation during conventional dental treatment. This cohort study compared atraumatic restorative treatment (ART), silver modified atraumatic restorative treatment (SMART), and conventional restorative treatment (CRT), in terms of feasibility and acceptability in patients referred for special care dentistry in a specialized university clinic.

Methods: Patients referred for dental restorative care were treated using either ART, SMART, or CRT approach.
