The researchers of the group 'Diagnosis by image and veterinary anesthesia' of the University of Murcia, Eliseo Belda Mellado and Marta Soler Laguía, analyze the injuries that are produced by the administration of local anesthetics, whose results would be applicable in animal and human medicine.
His research has been echoed in journals such as Veterinary Journal, Veterinary Radiology and Ultrasound, or in the Veterinary Anaesthesia and Analgesia, exclusive magazine of veterinary anesthesia with more diffusion worldwide.
Currently, they are working on the intraneural administration of a predetermined dose of a local anesthetic in the sciatic nerve, using the rabbit as a model.
The objective is to observe the alterations at the ultrasound and functional level during the immediate postoperative period.
This project aims to elucidate the evolution of an injury produced during the administration of local anesthetics.
That is, to study the intraneural lesion caused by the deposit of these anesthetics.
Although not too often, this event results in the afunctionality of the nerve, the inability to move a limb or the inability to perceive a sensitive stimulus.
Previously, a similar study has been carried out in pigs, which has allowed them to be published in the Veterinary Journal.
The examination was based on the surgical approach of the sciatic nerve in pigs, specifically administering lidocaine to assess, at different times, the evolution by means of ultrasound.
In the same way, it was evaluated if it had motor or sensitive deficits.
The result of the article showed that the injuries were transient and did not leave a sequel.
With this in mind, researchers warn that there is a danger, in a minimum percentage, of an injury that lasts over time.
The expert specifies that they chose this line because of the growing interest in locoregional anesthesia techniques in animals and humans, which allows not to undergo general anesthesia and reduce risks.
But there are difficulties in selectively blocking specific nerves.
Although traditionally it has been done blindly, introducing a needle without being able to see, in recent years has been established electrostimulation, stimulating the nerve and producing a muscle contraction.
The problem with this method is to puncture the nerve by mistake and administer the anesthetic inside, which could lead to a transient or permanent sequelae.
To avoid this, during the last 10 years, visual localization procedures have been developed.
From this context, his research team examines what happens by deliberately puncturing the nerve, hence the research in rabbits and pigs.
Although it is experimented on animals, the results are applicable in both animal and human medicine.
On the other hand, animal medicine has evolved in recent years.
From the perspective of the ecologist, imaging techniques have developed exponentially.
The teams have gone from having to imagine what you saw to a photographic definition.
For the anesthesiologist, the technique, knowledge and veterinary training have advanced dramatically in the clinical field.
The question is to equate this capacity with resources that are often difficult to acquire.
Far from the image of theoretical teachers, its function, from the care work in the Veterinary Clinical Hospital, is to transmit the experience in the resolution of cases to the students.
In particular, specific Belda who enjoys "imparting the subject of" Veterinary Anesthesia "in the degree of Veterinary, and 'Anesthesiology' in a master's degree of postgraduate";
and Soler works "teaching in the subject of 'Diagnostic Imaging' and 'Diagnostic Imaging Techniques' in a postgraduate master's degree, being eminently practical subjects in the Veterinary Hospital.
In the same way, they depend on the cases to teach correctly.
As the professor defends: "We can not be room matadors".
In other words, what is theoretically explained must be supported by daily practice.
For them, teaching has to be based on clinical cases, many of them referred by other colleagues, thus providing support to veterinarians with lack of means to resolve certain incidents.
With the importance of education in mind, both agree that they entered with a clinical vocation, but teaching has been equated with the years.
The combination of both is the greatest satisfaction: to show and educate the students what they do in the clinical field.
Combining education, research and care work becomes the most profitable: the animal of care work, specifically serves to teach and can be included in a study.
