Beside others, neuroinhibitory and sedative effects of CBD were documented. The aim of the study was to assess the dose-related effects of CBD premedication on the course of isoflurane anesthesia. Wistar rats were pretreated with different doses of CBD 1 h before isoflurane anesthesia. In the pretreatment, animals were given CBD at doses of 100, 20, 10, or 2 mg kg. Before the fifth (control) anesthesia, the animals were given only mid-chain triglyceride oil, which served as a solvent in the CBD formulation. The induction time was determined, and on awakening, the time to appearance of the flexion reflex and the recovery from anesthesia were determined. Statistical analysis showed a significantly shorter induction time if animals were pretreated with 20 mg kg CBD. In addition, pretreatment with 100 mg kg CBD resulted in a prolonged induction time, while on awakening, delayed appearance of reflexes and prolonged recovery from anesthesia compared to pretreatment with 20 mg kg CBD were observed. The results indicate that the influence of CBD on the course of isoflurane anesthesia depends on the dose and can reduce the induction time. Although this study was performed in laboratory rats, in clinical practice, these data should be considered when CBD-treated patients undergo isoflurane anesthesia.

Pain management requires the identification of certain indicators to recognize pain. Various tools have been suggested to achieve an objective evaluation, including infrared thermography (IRT). The objective of this study was to assess the facial thermal nociceptive response produced by the use of cannabidiol (CBD) alone and in combination with meloxicam in female dogs undergoing elective ovariohysterectomy anesthetized with isoflurane.

Background: The purpose of this study is to evaluate differences in transdiaphragmatic pressure (Pdi) in dogs suffering from cervical myelopathy (CM) and thoracolumbar myelopathy (TLM) anaesthetised with isoflurane (ISO).
Methods: This prospective cohort study included ASA II-status dogs diagnosed with either CM or TLM, anaesthetised for diagnostic or surgical purposes between September 2021 and July 2023. Patients followed the same anaesthetic protocol, and maximum Pdi was recorded at 10 (Pdimax10), 20 (Pdimax20), and 30 (Pdimax30) minutes using balloon catheters placed in the stomach (Pgast) and in the mid-third of the oesophagus (Poes).

Background: Anesthesia can significantly impact positron emission tomography (PET) neuroimaging in preclinical studies. Therefore, understanding these effects is crucial for accurate interpretation of the results. In this experiment, we investigate the effect of [F]-labeled glucose analog fluorodeoxyglucose ([F]FDG) uptake in the brains of rats anesthetized with two commonly used anesthetics for rodents: isoflurane, an inhalation anesthetic, and Hypnorm-Dormicum, a combination injection anesthetic.

Background: Microcirculation is the essential link between macrocirculation and cellular metabolism.
Objectives: To test our hypotheses that microcirculation variables will show a heterogeneous flow pattern during experimental endotoxaemia, and that fluid therapy and noradrenaline (NA) infusion will normalise altered microcirculation variables.
Study Design: In vivo experiments.
