Head: o.Univ.Prof.Dr. Paula Larenza-Menzies, PhD, Dip ECVAA


The international recognized veterinary anaesthetist ressumed the professorship as well as the leadership of the department of Anaesthesiology and Perioperative Intensive Care at the University of Veterinary Medicine in Vienna end of 2015. The native Argentinian specialised the field of animal anaesthesia and pain treatment. She worked among other things on developing a novel anaesthetic for horses, cats and dogs, which has better anaesthesia quality and can be brocken down by the body faster.

Research and scientific activity

Dr. Larenza Menzies’ research is oriented towards improving the safety of anesthetic techniques in veterinary patients, either by developing newer anesthetic agents, loco-regional techniques that decrease the need for general anesthetics, or by investigating complications related with de delivery of anesthesia. In this context Dr. Larenza Menzies has developed her research in the following areas:

  1. S-ketamine pharmacology in horses, cats and dogs: The pharmacokinetics and pharmacodynamics of this enantiomer was extensively studied by Dr. Larenza Menzies. In brief, her results show that S-ketamine is eliminated faster and provides better anesthetic qualities than the racemate.
  2. Aspiration pneumonia in dogs: The results of a multicenter study in showed that some analgesic agents like opioids might increase the risk for aspiration pneumonia. Alternative analgesic techniques (e.g. local blocks) should be investigated.
  3. Locoregional techniques in dogs and rabbits: The results of two studies performed by Dr. Larenza Menzies and collaborators in dogs and rabbits showed that desensitization of the sciatic and femoral nerves in dogs and rabbits may provide suitable anti-nociception and postoperative analgesia for stifle joint surgery. Thus, this technique may reduce the complications associated with the administration of epidural agents, or systemic analgesics and high concentrations of general anesthetics. Additionally, research was also performed with ultrasound-guided techniques to desensitize the brachial plexus in dogs aiming for similar results.
  4. Minimizing Alpha-2 cardiovascular side effects: current research is being performed to identify the advantages of using an agent that minimizes the side effects of alpha-2 agonists without interfering with their main sedative and analgesic effects. In this context, peripheral receptor antagonists or alpha-1 blockers are investigated.
  5. Ventilation and oxygenation: research was conducted by Dr. Larenza Menzies in collaboration with the University of Bari to test beside formulas use to assess oxygenation in anesthetized patients. Similarly, special mechanical ventilation techniques (i.e. one-lung ventilation, positive-end expiratory ventilation, recruitment maneuvers, etc.) were studied/reported in dogs, alpacas, goats and sheep.
  6. Cancer recurrence and anesthesia: Dr. Larenza Menzies is currently investigating the effects of opioid analgesic vs. local anesthetic agents with the aid of a PhD student.
