RESUMEN
PURPOSE: This paper proposes a practical model of microneurosurgical training using a nonliving swine head. METHODS: Fresh porcine heads were obtained from butchery and dissected at our Laboratory of Microsurgery. Brain and skull base surgery were trained under microscopic magnification. RESULTS: Several neurosurgical procedures could be simulated in the nonliving pig model, including transcallosal approach to the lateral ventricle, lateral sulcus and middle fossa dissection, and posterior fossa surgery. CONCLUSION: The swine model perfectly simulates standard microneurosurgical procedures, and is a useful tool for developing and refining surgical skills. .

JUSTIFICATIVA E OBJETIVOS: Devido à finalidade do ambulatório e os fármacos utilizados rotineiramente, o objetivo deste estudo foi rever e atualizar os conhecimentos sobre os receptores opioides e como complemento de estudo após palestra apresentada aos integrantes da equipe. CONTEÚDO: Foram revisados desde os aspectos históricos até os conhecimentos mais recentes sobre receptores opioides, descritos seus subtipos e mecanismos de ação. Para tal, foram consultadas referências indexadas pelo Pubmed. CONCLUSÃO: Com os dados presentes na literatura atual, concluiu-se que ainda existe muito a ser pesquisado sobre o tópico, visando medicações mais seguras e novas técnicas biomoleculares ainda são necessárias.
BACKGROUND AND OBJECTIVES: Due to the objective of the outpatient setting and to routinely used drugs, this study aimed at reviewing and updating the knowledge about opioid receptors and worked as a study complement after a lecture presented to team members. CONTENTS: We have reviewed from historical aspects to most recent developments about opioid receptors, in addition to describing subtypes and action mechanisms. For such, Pubmed-indexed references were queried. CONCLUSION: After reviewing current literature data, we have concluded that there is still a lot to be researched about the topic, aiming at safer drugs, and new biomolecular techniques are still needed.
