Project description:Background Airway management for thoracic surgery represents a high risk setting for SARS-CoV-2 infection diffusion due to complex and invasive airway instrumentation and techniques. Results An 18-item questionnaire was submitted to the 56 members of the Thoracic subcommittee of the SIAARTI Cardio-Thoraco-Vascular Research Group to provide a snapshot of current situation and national variability of devices and procedures for airway management during the COVID-19 pandemic. The response rate was 64%. Eighty-three percent of anesthetists declared that they modified their airway management strategies. The Hospital Management considered necessary to provide a complete level 3 personal protective equipment for thoracic anesthetists only in 47% of cases. Double-lumen tube and bronchial blocker were preferred by 53% and 22% of responders to achieve one-lung ventilation respectively. Over 90% of responders considered the videolaryngoscope with separate screen and rapid sequence induction/intubation useful to minimize the infection risk. Thirty-nine percent of participants considered mandatory the bronchoscopic check of airway devices. Vivasight-DL was considered comfortable by more than 50% of responders while protective box and plastic drape were judged as uncomfortable by most of anesthetists. Conclusions The survey reveals many changes in the clinical practice due to SARS-CoV-2 outbreak. A certain diffusion of new devices such as the VivaSight-DL and barrier enclosure systems emerged too. Finally, we found that most of Italian hospitals did not recognize thoracic anesthesia as a high-risk specialty for risk of virus diffusion.

Project description:The COVID-19 pandemic led to rapid changes in care delivery for critically ill patients, due to factors including increased numbers of ICU patients, shifting staff roles, and changed care locations. As these changes may have impacted the care of patients without COVID-19, we assessed changes in common ICU practices for mechanically ventilated patients with non-COVID acute respiratory failure at the onset of and during the COVID-19 pandemic.DesignInterrupted time series analysis, adjusted for seasonality and autocorrelation where present, evaluating trends in common ICU practices prior to the pandemic (March 2016 to February 2020), at the onset of the pandemic (April 2020) and intra-pandemic (April 2020 to December 2020).SettingPremier Healthcare Database, containing data from 25% of U.S. discharges from January 1, 2016, to December 31, 2020.PatientsPatients without COVID-19 receiving mechanical ventilation for acute respiratory failure.InterventionsWe assessed monthly rates of chest radiograph (CXR), chest CT scans, lower extremity noninvasive vascular testing (LENI), bronchoscopy, arterial catheters, and central venous catheters.Measurements and main resultsWe identified 742,096 mechanically ventilated patients without COVID-19 at 545 hospitals. At the onset of the pandemic, CXR (-0.5% [-0.9% to -0.2%; p = 0.001]), LENI (LENI: -2.1% [-3.3% to -0.9%; p = 0.001]), and bronchoscopy rates (-1.0% [-1.5% to -0.6%; p < 0.001]) decreased; use of chest CT increased (1.5% [0.5-2.5%; p = 0.006]). Use of arterial lines and central venous catheters did not change significantly. Intra-pandemic, LENI (0.5% [0.3-0.7%; p < 0.001]/mo) and bronchoscopy (0.1% [0.05-0.2%; p < 0.001]/mo) trends increased relative to pre-pandemic trends, while the remainder of practices did not change significantly.ConclusionsWe observed several statistically significant changes to practice patterns among patients without COVID-19 early during the pandemic. However, most of the changes were small or temporary, suggesting that routine practices in the care of mechanically ventilated patients in the ICU was not drastically affected by the pandemic.

Project description:BackgroundOne lung ventilation (OLV) is the technique used during lung resection surgery in order to facilitate optimal surgical conditions. OLV may result in hypoxemia due to the shunt created. Several techniques are used to overcome the hypoxemia, one of which is continuous positive airway pressure (CPAP) to the non-dependent lung. Another technique is ventilating the non-dependent lung with a minimal volume, thus creating differential lung ventilation (DLV). In this study we compared the efficacy of CPAP to DLV during video assisted thoracoscopic lung resection.Patients and methodThis is a prospective study of 30 adult patients undergoing elective video assisted thoracoscopic lung lobectomy. Each patient was ventilated in four modes: two lung ventilation, OLV, OLV + CPAP and OLV + DLV. Fifteen patients were ventilated with CPAP first and DLV next, and the other 15 were ventilated with DLV first and then CPAP. Five minutes separated each mode, during which the non-dependent lung was open to room air. We measured the patient's arterial blood gas during each mode of ventilation. The surgeons, who were blinded to the ventilation technique, were asked to assess the surgical conditions at each stage.ResultsOxygenation during OLV+ CPAP was significantly lower that OLV + DLV (p = 0.018). There were insignificant alterations of pH, PCO2 and HCO3 during the different ventilating modes. The surgeons' assessments of interference in the field exposure between OLV + CPAP or OLV + DLV was found to be insignificant (p = 0.073).ConclusionsDuring OLV, DLV is superior to CPAP in improving patient's oxygenation, and may be used where CPAP failed.Trial registrationClinicalTrials.gov NCT03563612 .

Project description:BackgroundDuring thoracoscopic surgery with one-lung ventilation (OLV), achieving lung collapse is critical for providing surgeons with a good visibility of the surgical field and to minimise tissue compression. The aim of this study was to evaluate the efficacy of both the disconnection technique and preemptive one-lung ventilation in facilitating lung collapse during thoracoscopic surgery using a double-lumen tube (DLT).MethodsNinety-seven eligible patients were included and randomly divided into three groups.Control groupOLV was initiated when the surgeon started the skin incision and exposed the operative side. Disconnection group: OLV was started two minutes after the DLT was disconnected, this procedure started when the surgeon performed the skin incision. Preemptive group: OLV was initiated promptly after the patient was turned to the lateral position, and the bronchial tube port was clamped on the operative side at the lateral position for no less than 6 min until the pleura was opened. The primary outcome was the time to achieve satisfactory lung collapse, defined as the time required to reach a lung collapse score of eight points. The secondary outcomes included the lung collapse scores at different time points, Pleural opening times, OLV times, blood gas analysis results and the incidence of hypoxemia and pulmonary complications. The hypothesis formulated before data collection was that both the disconnection technique and preemptive OLV decrease the time to satisfactory lung collapse.ResultsCompared to the control group, both the disconnection and the preemptive group had a shorter time to satisfactory lung collapse (P < 0.001), lung collapse in the preemptive group was superior to that in the disconnection group at one minute (P = 0.045), no significant differences were found among the three groups in terms of other outcomes.ConclusionBoth the disconnection technique and preemptive OLV decrease the time to satisfactory lung collapse. However, preemptive OLV results in superior early lung collapse and is therefore may more suitable for clinical application than the disconnection technique.Trial registrationThe protocol of this study was registered at www. chictr. org. cn (29/07/2022, ChiCTR2200062199).

Project description:In this study, single-lung ventilation was used to detect differences in the volatile organic compound (VOCs) profiles between lung tissues in healthy and affected lungs. In addition, changes that occurred after lung cancer resection in both the VOCs profiles of exhaled breath from ipsilateral and contralateral lungs and the VOCs profiles of exhaled breath and blood sample headspaces were also determined. Eighteen patients with non-small cell carcinoma were enrolled. Alveolar breath samples were taken separately from healthy and diseased lungs before and after the tumor resection. Solid phase microextraction-gas chromatography/mass spectrometry was used to assess the exhaled VOCs of the study participants. The VOCs exhibited significant differences between the contralateral and ipsilateral lungs before surgery, the contralateral and ipsilateral lungs after surgery, the ipsilateral lungs before and after surgery, and the blood samples from before and after surgery; 12, 19, 12 and 5 characteristic metabolites played decisive roles in sample classification, respectively. 2,2-Dimethyldecane, tetradecane, 2,2,4,6,6-pentamethylheptane, 2,3,4-trimethyldecane, nonane, 3,4,5,6-tetramethyloctane, and hexadecane may be generated from lipid peroxidation during surgery. Caprolactam and propanoic acid may be more promising exhaled breath biomarkers for lung cancer.
