For perioperative mechanical ventilation under general anesthesia, modern respirators aim at combining the benefits of pressure-controlled ventilation (PCV) and volume-controlled ventilation (VCV) in modes typically named “volume-guaranteed” or “volume-targeted” pressure-controlled ventilation (PCV-VG). This systematic review and meta-analysis tested the hypothesis that PCV-VG modes of ventilation could be beneficial in terms of improved airway pressures (Ppeak, Pplateau, Pmean), dynamic compliance (Cdyn), or arterial blood gases (PaO2, PaCO2) in adults undergoing elective surgery under general anesthesia. Three major medical electronic databases were searched with predefined search strategies and publications were systematically evaluated according to the Cochrane Review Methods. Continuous variables were tested for mean differences using the inverse variance method and 95% confidence intervals (CI) were calculated. Based on the assumption that intervention effects across studies were not identical, a random effects model was chosen. Assessment for heterogeneity was performed with the χ2 test and the I2 statistic. As primary endpoints, Ppeak, Pplateau, Pmean, Cdyn, PaO2, and PaCO2 were evaluated. Of the 725 publications identified, 17 finally met eligibility criteria, with a total of 929 patients recruited. Under supine two-lung ventilation, PCV-VG resulted in significantly reduced Ppeak (15 studies) and Pplateau (9 studies) as well as higher Cdyn (9 studies), compared with VCV [random effects models; Ppeak: CI −3.26 to −1.47; p < 0.001; I2 = 82%; Pplateau: −3.12 to −0.12; p = 0.03; I2 = 90%; Cdyn: CI 3.42 to 8.65; p < 0.001; I2 = 90%]. For one-lung ventilation (8 studies), PCV-VG allowed for significantly lower Ppeak and higher PaO2 compared with VCV. In Trendelenburg position (5 studies), this effect was significant for Ppeak only. This systematic review and meta-analysis demonstrates that volume-targeting, pressure-controlled ventilation modes may provide benefits with respect to the improved airway dynamics in two- and one-lung ventilation, and improved oxygenation in one-lung ventilation in adults undergoing elective surgery.

Video Assisted Thoracoscopic Surgery

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.
