Introduction. Thoracic epidural analgesia, combined with general anesthesia, is an established anesthetic choice for abdominal aortic surgery. However, there are controversies about the level of anesthesia as well as the dose and concentration of the local anesthetic used. The aim of the study was to compare the effects of two different concentrations of epidural bupivacaine on sevoflurane requirements and hemodynamic parameters during aortic surgery under combined epidural/general anesthesia. Methods and Material. Sixty patients scheduled for abdominal aortic surgery were randomly divided into two groups according to the concentration of local anesthetic used for epidural anesthesia: - Group 1- low concentration - where 0.125% bupivacaine was used, and - Group 2 - high concentration - where 0.5% bupivacaine was used at the beginning and then the concentration was reduced to 0.25%. Anesthesia was maintained with sevoflurane, the dose was adjusted to achieve the target entropy of 40-60. The measurements included the inspired sevoflurane concentrations, blood pressure, and heart rate at the beginning and every 5 min during the surgery. Results. Both groups had similar heart rate and blood pressure, but the inspired sevoflurane concentration was significantly higher and more variable in patients where bupivacaine 0.125% was used. Vasopressors were used more often and in higher doses in the 0.5% bupivacaine group, and in the same group the blood loss and fluid requirements were reduced. Conclusion. When 0.5% bupivacaine is used in combined thoracic epidural/ general anesthesia for aortic surgery, the sevoflurane concentrations are lower and less variable. In addition, the blood loss and fluid requirements are reduced.

Background: In the last years thoracic surgery developed in greater extent with equipments and techniques in one lung ventilation. Still general anesthesia in one lung ventilation approved as gold standard. In thoracic surgery most performed surgeries are plerural decortication and lung biopsy. Avoidance of intubation in Video Assisted Thoracoscopic Surgery (VATS) procedures gains us some advantages in postoperative period; a better respiratory parameters, survival and morbidity mortality rates, reduced hospitalization time and costs, reduced early stress hormone and immune response.  Methods: In this study, we reported our experience of 24 consecutive patients undergoing VATS with Thoracic Epidural Anesthesia (TEA) between December 2015 through July 2016 to evaluate the feasibility, safety and indication of this innovative technique whether it will be a gold standart in thoracic surgeries or not in the future.Results: Operation procedures included wedge resection in 11 (46%) patients (eight of them for pneumothorax, three of them for diagnosis), in 10 (42%) patients pleural biopsy (eight of them used talc pleurodesis), in two (8%) patients air leak control with fibrin glue and in one (4%) patient bilateral thoracal sympathectomy for hyperhidrosis.  We used T4-5 TEA space for 17 (72%) of patients, while we used T4-6 TEA space for 7 (28%) of patients. TEA block reached the desired level after the mean 26.4±4.3 minutes (range 21-34 min). There was no occurrence of hypotension and bradycardia during and after TEA. One (4%) patient required conversion to general anesthesia and tracheal intubation because of significant diaphragmatic contractions and hyperpne. Conversion to thoracotomy was not needed in any patient.Conclusions: We conclude that nVATS procedure with aid of TEA is feasibile and safety with minimal adverse events. The procedure can have such advantages as early mobilization, opening of early oral intake, early discharge, patient satisfaction, low pain level. Nevertheless, there is a need for randomized controlled trials involving wider case series on the subject.
