ABSTRACT

Objective: Of showing that one obtains bigger degree and duration analgesic and smaller adverse effects when the hydrochlorate is used from Ropivacaine to 2% more midazolam, compared with the administration of ropivacaine hydrochlorate but and fentanyl or ropivacaine hydrochlorate with buprenorfine in postoperative analgesia in continuous infusion in abdominal surgery in the North Central Hospital of PEMEX. Material and Methods: We were carried out a clinical, observational study, prospective in 62 patients with physical state of theASAI and II. It was divided in 3 groups with 21 patients´ average for group: To the Group I was administered ropivacaine Hydrochlorate and midazolam; to the Group II were administered Hydrochlorate of ropivacaine more buprenorfine and to the Group III were administered hydrochlorate of ropivacaine more buprenorfine, using infusor elastomérico for continuous infusion in the three groups. FC, FR was evaluated TA, adverse effects and similar visual scale (EVA). Results: When applying the test OR of Mann Whitney was significancia in relation to theEVAit was of88%in the Group IIIa p‹0.019 and the percentage of analgesic effectiveness for the Group II82% and Group I 76%. In the duration analgesic measure during 36 hrs were not significant differences in the three groups.The predominant adverse effect was sickness (23.8%) and sedation 14.3%. In the Group II the adverse effectwasit nauseates 35%, followed by pruritus 20%. In the Group III the adverse effect that presents was pruritus in 38% followed by it nauseates 14.3%. Conclusions: The three groups completed the objective wanted for postoperative analgesia, being sure and effective. However the group of Ropivacaine and fentanyl in continuous infusion offer a more lingering analgesic duration.
