Anesthesia for thoracic surgery requires specialist intervention to provide adequate operating conditions and one-lung ventilation. The pandemic caused by severe acute respiratory syndromeÀassociated coronavirus 2 (SARS-CoV-2) is transmitted by aerosol and droplet spread. Because of its virulence, there is a risk of transmission to healthcare workers if appropriate preventive measures are not taken. Coronavirus disease 2019 (COVID-19) patients may show no clinical signs at the early stages of the disease or even remain asymptomatic for the whole course of the disease. Despite the lack of symptoms, they may be able to transfer the virus. Unfortunately, during current COVID-19 testing procedures, about 30% of tests are associated with a false-negative result. For these reasons, standard practice is to assume all patients are COVID-19 positive regardless of swab results. Here, the authors present the recommendations produced by the Israeli Society of Anesthesiologists for use in thoracic anesthesia for elective surgery during the COVID-19 pandemic for both the general population and COVID-19Àconfirmed patients. The objective of these recommendations is to make changes to some routine techniques in thoracic anesthesia to augment patients' and the medical staff's safety.

Background: The highly contagious COVID-19 has created unprecedented challenges in providing care to patients with resectable non-small cell lung carcinoma (NSCLC). Surgical management now needs to consider the risks of malignant disease progression by delaying surgery, and those of COVID-19 transmission to patients and operating room staff. The goal of our study was to describe our experience in providing both emergent and elective surgical procedures for patients with NSCLC during the COVID-19 pandemic in Israel, and to present our point of view regarding the safety of performing lung cancer surgery. Methods: This observational cross-sectional study included all consecutive patients with NSCLC who operated at Tel Aviv Medical Center, a large university-affiliated hospital, from February 2020 through December 2020, during the COVID-19 pandemic in Israel. The patients’ demographics, COVID-19 preoperative screening results, type and side of surgery, pathology results, morbidity and mortality rates, postoperative complications, including pulmonary complications management, and hospital stay were evaluated. Results: Included in the study were 113 patients, 68 males (60.2%) and 45 females (39.8%), with a median age of 68.2 years (range, 41–89). Of these 113 patients, 83 (73.5%) underwent video-assisted thoracic surgeries (VATS), and 30 (26.5%) underwent thoracotomies. Fifty-five patients (48.7%) were preoperatively screened for COVID-19 and received negative results. Fifty-six postoperative complications were reported in 35 patients (30.9%). A prolonged air leak was detected in 11 patients (9.7%), atrial fibrillation in 11 patients (9.7%), empyema in 5 patients (4.4%), pneumonia in 9 patients (7.9%) and lobar atelectasis in 7 patients (6.2%). Three patients (2.7%) with postoperative pulmonary complications required mechanical ventilation, and two of them (1.6%) underwent tracheostomy. Two patients (1.6%) were postoperatively diagnosed as positive for COVID-19. Conclusions: Our data demonstrate the feasibility and efficacy of implementing precautionary strategies to ensure the safety of lung cancer patients undergoing pulmonary resection during the COVID-19 pandemic. The strategy was equally effective in protecting the surgical staff and healthcare providers, and we recommend performing lung cancer surgery during the pandemic era.

Introduction: Simulation is an essential component of medical education. Commercially available intubation simulators often lack anatomical fidelity of the lower airway and are therefore not suitable for teaching bronchoscopy or lung isolation. By using a desktop 3-dimensional (3D) printer, we aimed to create and validate a hybrid simulator from an existing mannequin with a 3D-printed lower airway that has anatomical fidelity and is financially affordable compared with commercially available models. Methods: Using an anonymized computed tomography scan of an adult male patient, we developed a 3D model of the airway from below the larynx to the 3rd generation bronchi, which was then printed on a desktop 3D printer. The printed airway was attached to an existing mannequin below the larynx via a universal adaptor. Ten anesthesiology attendings performed a blinded comparison of the hybrid mannequin with a commercially available mannequin for tactile and visual fidelity when performing intubation, bronchoscopy, and lung isolation. They were also asked to assess the models for educational suitability. Results: The 3D printed model was judged more suitable for teaching double-lumen tube insertion to novice physicians compared with the commercial model, with median (interquartile range) scores of 5 (4-5) versus 3 (2-4), P = 0.017. Similar results were found for bronchial blocker insertion and bronchoscopy. The visual fidelity of the bronchial anatomy was scored as 5 (4-5) and 2 (1-3) for the 3D-printed and the commercial models, respectively ( P = 0.007). Conclusion: By creating a hybrid model combining an existing commercially available mannequin with a 3D-printed trachea and bronchial tree, we have created an affordable training simulator suitable for teaching lung isolation and bronchoscopy. Enhancing existing mannequins with 3D-printed parts may be of particular interest to institutions that do not have the funds to buy models with anatomical fidelity but do have access to a 3D printer.
