AGRADECIMENTOSAgradeço aos que me acompanharam nesta trajetória e com seu conhecimento, compreensão, amizade, competência, para que esta tese fosse possível e se tornasse realidade, ao Professor Dr. Miguel Srougi, Professor Dr. Homero Bruschini e Professor Dr. Alberto Azoubel Antunes.Ao meu orientador Professor Dr. Carlo Camargo Passerotti, pela orientação, ensinamento, confiança e competência.A Sabrina Reis, pela amizade, paciência e ajuda. ,25% e 15,4% had more than 5mg of morphine on postoperative care unit), patients that received DEX intraoperatively, required higher doses of morphine on postoperative care unit.The DEX group presented more patients with severe pain (84,6%) and fewer without pain(15,4%).The use of DEX intraoperatively lead to a reduction of non-opioid use in postanesthesia care unit and neither patients had non opioid analgesia , when morphine is associated to DEX 2,8% received, and with the other two groups 12,5% (p=0,083). The DEX and morphine received less morphine than the other groups on postanesthesia care unit (59% received any morphine)(p=0,135).On immediate postoperative period and first postoperative period , 100% received any morphine(p=0,555), this group had more patients with lesser pain, 48,7% had no pain on postanesthesia care unit e 51,3% on immediate postoperative period. The combination of DEX and morphine lead to an impressive reduction of pain on immediate postoperative period(10,3%),patients had about 8 times less severe pain than the group that did not receive neither morphine or DEX(81,3%)(p=0,000).Conclusion: The use of DEX infusion was not suitable regarding morphine spare and reduction of pain of the patients undergoing robotic-assisted radical prostatectomy. An association between DEX and Morphine seems to be the best option to relieve post-op pain and decrease morphine usage.
