Introduction: Radiofrecuency thermocoagulation is a minimal invasion procedure for irresectable lung tumors, anesthesic technique for this procedures is still not well described. Treated lung must be colapsed for better surgical view and manipulation, and decrease procedure complications. Objective: Report our experience with one lung ventilation for patients subject to radiofrecuency edigraphic.org.mx thermocoagulation for irresectable lung tumors. Material: We include four patients subject to thermocoagulation of lung tumors, tomographic control and general anesthesia with one lung ventilation. Method: Not invasive monitoring, general anesthesia with intravenous induction, left Broncho-Cath placement, O2 ventilation, treated lung clamping for colapse an at the end reexpantion. Result: Four patients were incluided in this study. During the procedure only one patient present minimal bleeding, without functional lung damage, recidivant bleeding and in posterior control there were no patients with pneumothorax or bleeding. Conclusions: One lung ventilation on lung tumors radiofrecuency is a viable and safe procedure and can reduce complications and facilitates maneouverability. [ABSTRACT FROM AUTHOR]

We conducted a retrospective and prospective study to compare the effects of Dexmedetomidine (Dx) on the use of intravenous anesthetics, sedation level, hemodynamic changes, postoperative pain, nausea and vomiting. Methods: Seventy-eight ASA I-III patients scheduled for radiofrecuency ablations of saphenous vein with local anesthetics were included, 38 received Dx 1 µg/kg for 10 minutes. Maintenance was with midazolam, fentanyl and propofol for control of pain and level ≤ 2 sedation (OOA). Results: Demographic data were similar in both groups. The Dx group resulted in a significant reduction in use of midazolam and propofol, without changes in use of fentanyl. In 2007, 85% received propofol and in 2008 only 33% needed this. Dx resulted in a significant decrease in heart rate. Conclusions: Dx used during radiofrecuency ablations of saphenous veins reduced the use of midazolam and propofol, in some case propofol was not used. Hemodynamic changes were minimal.
