Filter by:A total of eight quadrants of standard lung US examination was performed to all pregnant women with preeclampsia within the scope of the study by the same anesthesiologist, dividing each hemithorax into four regions through the parasternal, anterior axillary, posterior axillary vertical lines, and the horizontal line assumed to pass under the nipple. The resulting images were stored in digital media. A Lung US examination was performed once for an average of 5-10 minutes. The presence of B lines was investigated in the examination. The case was defined as interstitial edema when the B lines, which are defined as vertical linear hyperechoic reverberation artifacts representing the edematous interlobular septa/alveoli, extend posteriorly from below the pleural line and moving in sync with lung movements, are found in two or more lung areas. B-lines were determined for each case and reported in standard form in terms of number and morphology. The diagnostic accuracy of B lines was determined with the artificial intelligence supported SmartAlpha Rievi 1300 software program. B-lines validated by artificial intelligence assisted algorithm in all stored digital images were reported blindly by another anesthesiologist experienced in lung US. The clinical features, laboratory parameters, and intraoperative hemodynamic data of the cases were recorded to be evaluated in terms of relationship with lung US data. We predict that the application of lung US with artificial intelligence software will provide an opportunity to quickly evaluate the clinic of preeclamptic pregnant women who are frequently operated on in emergency conditions.
Sepsis is one of the most challenging conditions with an exceptionally high mortality rate. Diastolic Dysfunction is common in septic patients and has been found to be associated with mortality. However, the reasons for this remain unclear. Therefore, the goal of this study is to investigate diastolic dysfunction in septic patients on the intensive care unit. Special attention is paid to the presence of lung edema and general edema as a potential link between diastolic dysfunction and elevated mortality in septic patients. During the septic phase daily ultrasound examinations of heart and lung will be performed as to monitor diastolic function and lung edema.
Patients submitted to general anesthesia and artificial ventilation almost always develop pulmonary atelectasis, which can determine adverse consequences both intraoperatively and postoperatively. It is recommended to use physiological tidal volume (6 - 8 mL / kg of ideal body weight) during the intraoperative period in order to minimize the risk of lung injury. To prevent the formation of atelectasis, minimizing the risk of complications, the use of PEEP has been recommended. At present, there is no way to make an optimal adjustment of PEEP to the needs of each patient, seeking a value that keeps the alveoli open without forming atelectasis and also without areas of hyperdistension. The aim of this study was to evaluate the agreement between the ultrasound and the electrical impedance tomography - Timpel® (TIE) to detect the beginning of the formation of areas of atelectasis after pulmonary recruitment, with decreasing PEEP values. In addition, the lung ultrasound will be validated for intraoperative use for both adequacy of PEEP, as well as quantitative analyzes of ultrasound images to assess atelectasis. 18 patients (> 18 years) of both sexes, submitted to general anesthesia, will be prospectively studied. All patients will receive, in addition to the usual monitoring, the monitoring with the electrical impedance tomography and chest ultrasonography, after being anesthetized and under neuromuscular block, being ventilated with an inspired fraction of 50% oxygen (or greater to maintain oxygen saturation > 96% ), Tidal volume of 6 mL / kg and respiratory rate to maintain expiratory tidal CO2 between 35-45 cmH2O.
