The importance of pre-operative assessment and post-operative care in surgical procedures

  • Senior Scientist, Program Director of the Phenotyping Cores, University of Minnesota
      Pilar Ariza Guzman received her DVM from the University of La Salle, Bogota, Colombia and an M.S. from the University of Minnesota. In 2013 she became the Director of the Phenotyping core in Jackson Hall  and in the Cardiovascular and Cancer Research Building  (CCRB) for the University of Minnesota. The Cores are designed to integrate disciplines by offering the opportunity for investigators to use highly specialized equipment to conduct their research and have access to highly skilled services and surgeries. Guzman has extensive experience in lab management, rodent care and surgical techniques. From 1998 to 2013, Guzman had the opportunity to work with John Osborn to understand the role of the central nervous system in the long-term regulation of arterial pressure and the pathogenesis of hypertension. During this time she had the opportunity to develop and perfect a series of surgical techniques, which include abdominal interventions, open chest mostly in rats, nerve ablations, implantation of telemeters, Sub cutaneous implantations of minipumps and pellet. During this period of time she was also very involved in the collaboration of grants for the lab and her work included the following grants; 2000 - 2010    NIH Neural Mechanisms of Long-Term Cardiovascular Control, 2004 - 2009    NIH Long-term Neural Determinants of Cardiovascular Diseases. She was awarded in August, 2001 Outstanding Laboratory Personnel as a Scientist, Dept. of Animal Science, University of Minnesota.  One of her other important duties has been the involvement with the Research Animal Resources (RAR) and Institutional Animal Care and Use Committee (IACUC) inspections in different labs. This gave her the opportunity to learn more about the correct way to care for the animals in experimental studies.   From 1990 - 1996 she worked in the Research Institute of Colombia South America CORPOICA as a research scientist in animal nutrition.

    The pre-operative assessment and post-operative is critical for successful surgical procedures which will in turn lead to high quality outcomes in research studies. The care of the animals going through surgical procedures for any study starts at the moment you order them. Order the animals from the same vendor may avoid variations in the study outcomes. First, I want to point out that it is important to give the animal enough time to recover from the stress induced during the transportation and environment changes, which will reflect negatively later in the studies. Second, I will discuss the best methods to prepare the animal for the surgical procedures in order to avoid pain and reduce chances of infections. Third, I will present surgical techniques and discuss post-operative care.

    My objective for this presentation is to facilitate a better understanding of the importance of pre-operative assessment, post-operative care, and surgical techniques. Having a healthy and happy animal will give you the best results for any research study.
