Tips and Tricks in Experimental Nerve Defect Surgery

Microsurgery in itself might be considered a challenge for some plastic surgeons, as it requires patience and perseverance. Furthermore, when it comes to nerve surgery, the challenge is even greater as it implies a longer time necessary to observe results. In clinical practice, a good technique is associated with a good outcome. However, the problem of the recovery time remains an issue to be addressed by future generations. Nerve defects represent an even greater challenge in traumatology. Crush injuries, lacerations and avulsions may all lead to irreversible damage of the nerves. In such cases, special surgery techniques are required to restore function1-4. In order to prepare for these special techniques, a surgeon must begin with experimental in vivo nerve surgery and one that has the highest similarity with humans is the sciatic nerve of the Wistar rat5.

Main Concerns in the Romanian Medical System – a Doctors Perspective Over the Last 3 Years

All medical societies struggle with different problems. While in developed countries, the main complaint of the doctors is related to overwork due to insufficient personnel, the Romania doctors have many other reasons for being dissatisfied with the activities they perform. The aim of this article is to compare how the doctors’ problems have evolved over the last 3 years, which problems have been solved and which still need to be confronted. In order to do this, an analysis of 2 set of surveys will be performed, one conducted in 2016 by the Multidisciplinary Society of Medical Residents (SMMR) and one conducted in 2019 by the Romanian Federation of Medical Students’ Associations. Both societies – one of the medical residents, the other representing the medical students, have shown a great interest in revealing the problems of the Romanian medical health care system, which has a great impact both on patients as well as medical personnel dynamics.

Timing, Logistics and Bureaucratic Process in Planning an Experimental In Vivo Nerve Regeneration Project from A to Z

Every research project begins with an idea and a theory. After a thorough examination of previous publications related to the idea (in order not to re-invent the wheel), the idea must be put in practice to test the hypothesis. When it comes to in vivo experiments, there are several bureaucratic demands which need to be fulfi lled before commencing any project. Furthermore, the experiments require similar clinical conditions for surgery and postoperative care in order to obtain irrefutable results. Apart from the logistics necessary for the surgical intervention and the postoperative care, logistics referring to proper accommodation and food supplies for the animals to be experimented on is also to be considered from the beginning. Last but not least, the human resource is most valuable in such projects, as the surgical interventions are time consuming and require for sterile conditions at least 2 people (the surgeon and the assistant). The personnel involved in the project needs to allocate time for the postoperative care, the following clinical tests as well as the daily time spent for cleaning, feeding and providing water for the animals in the study. In nerve regeneration studies, this can take up to months, therefore all the resources should be well planned before the beginning of the project.
