Analgesia

An Anglocentric history of anaesthetics and analgesics in the refinement of animal experiments

Previous histories of animal experimentation, e.g., Franco (2013) have focused on ethics, the law and the personalities involved, but not on the involvement of anaesthetics or analgesics. Given that these were major subjects of (UK) Parliamentary debates on vivisection in...

Clinical management of pain in rodents

The use of effective regimens for mitigating pain remain underutilized in research rodents despite the general acceptance of both the ethical imperative and regulatory requirements intended to maximize animal welfare. Factors contributing to this gap between the need for and...

Combination of ketamine and xylazine with opioids and acepromazine in rats: Physiological changes and their analgesic effect analysed by ultrasonic vocalization

In this study, the effect of four anaesthetic protocols that included the combination of xylazine (X) and ketamine (K) with acepromazine (A) and opioids (methadone (Me), morphine (Mo) or tramadol (T)) was evaluated in laboratory rats of both sexes. Ultrasonic...

Preliminary findings on a novel behavioural approach for the assessment of pain and analgesia in lambs subject to routine husbandry procedures

The identification and assessment of pain in sheep under field conditions are important, but, due to their stoic nature, are fraught with many challenges. In Australia, various husbandry procedures that are documented to cause pain are routinely performed at lamb...

Improving pain management for murine orthotopic xenograft models of acute lymphoblastic leukemia

Despite ongoing research, realistic in vitro models for acute lymphoblastic leukemia (ALL) that can mimic the complex pathology are still not available, highlighting the need for continuous animal-based investigation. As part of the 3R principles, constant refinement of animal experiments...

Behavioral assessment of tramadol and meloxicam effects on postoperative pain in a rat craniotomy model

Stereotaxic surgery is a common procedure in neuroscience, yet effective analgesic protocols require further study and refinement to optimize the analgesia used in invasive procedures and to improve animal welfare. This study evaluated the effects of tramadol and meloxicam, alone...

Comparison of the anxiolytic and analgesic effects of gabapentin and pregabalin in cats: A systematic review

The present study aimed to systematically review the anxiolytic and analgesic effects of gabapentin and pregabalin in domestic cats to assess the quality of using these medications for stress, fear, and anxiety management, and the treatment of both acute and...

Comparison of different formulations of extended-release buprenorphine in perioperative pain management in common marmosets (Callithrix jacchus)

Common marmosets (Callithrix jacchus) are increasingly used in biomedical research and often undergo surgery as part of IACUC-approved protocols. Therefore, pain control is essential to their clinical management and welfare. Extended-release buprenorphine is a valuable opioid analgesic option, as it...
