Animal research and experimental surgery

Developed by: Instituto de Investigación Sanitaria Fundación Jiménez Díaz


The main tasks of the service are to house, raise, and maintain different experimental animals, providing researchers with the specimens necessary to carry out their projects. 

These animals must be housed in conditions that adhere to Spanish legislation for each species. Cages and housing modules must be kept in conditions that are environmentally sound and conducive to optimal hygiene and health. 

An experimental animal is a biological reagent, and as such must be provided with appropriate housing conditions so as to avoid unfavorable responses and anomalous experimental results. 

Experimental operating room 

The experimental operating room works mainly with researchers to develop and implement experimental models required for different lines of research as well as follow-up and collection of different biological samples for such models. 

Surgeons use the room when training in: 

  • New surgical techniques (digestive surgery, thoracic surgery, urology, orthopedic surgery); and 
  • Testing new devices and surgical materials done by medical staff. 


According to the provisions of Royal Decree 53/2013 of February 1, 2013, the Board of Environmental and Territorial Management—under the General Directorate for the Environment of the Madrid regional government—, being the body with authorization in these matters, designated the IIS-FJD and, in particular, its authorized committee, to evaluate research projects as well as perform retrospective analyses provided that all analyses comply with the requisites appearing in articles 39 and 43 of the aforementioned Royal Decree. 

Care-related work 

The animal research facility assists in taking biological samples from different animals when such samples are required for clinical activity (sporadic needs, such as allergy, microbiology, etc.). 

The facilities of the experimental operating room and animal housing area are properly equipped to house, raise, and maintain animals in accordance with legal requirements. The facilities also have the equipment necessary to prevent pain and suffering in the animals used. 

The number and species of animals used depends on the different lines of research to be carried out.
