Highlights-Thoracic anesthesiologists might be involved in the perioperative care of patients suspected to have or diagnosed COVID-19 who might undergo thoracic surgery during the acute or convalescence phases of the disease.-Caution should be exercised when securing the airway and performing lung separation (if required), through vigilant donning/doffing of personal protection equipment (PPE), planning ahead, team briefing, proper preparations, systematic approach, and debriefing.-Lung separation / isolation should be individualized using either bronchial blockers or double lumen tubes according to the patient"s status and postoperative care plan.-Optimum PPE donning should be maintained during surgery and anesthesia. One lung ventilation could be challenging in this group of patients.-The anesthesiologists should discuss the feasibility of extubating the patient following thoracic surgery, and procedures for postoperative care andtransferring the patient to the isolation wards or intensive care unit.Abstract 110 words, Manuscript 4935 words Running

BackgroundDespite the substantial progress in the quality of critical care, the incidence and mortality of acute kidney injury (AKI) continues to rise during hospital admissions. We conducted a national, multicenter, prospective, epidemiological survey to evaluate the importance of AKI in intensive care units (ICUs) in Hungary. The objectives of this study were to determine the incidence of AKI in ICU patients; to characterize the differences in aetiology, illness severity and clinical practice; and to determine the influencing factors of the development of AKI and the patients' outcomes.MethodsWe analysed the demographic, morbidity, treatment modality and outcome data of patients (n = 459) admitted to ICUs between October 1st, 2009 and November 30th, 2009 using a prospectively filled in electronic survey form in 7 representative ICUs.ResultsThe major reason for ICU admission was surgical in 64.3% of patients and medical in the remaining 35.7%. One-hundred-twelve patients (24.4%) had AKI. By AKIN criteria 11.5% had Stage 1, 5.4% had Stage 2 and 7.4% had Stage 3. In 44.0% of patients, AKI was associated with septic shock. Vasopressor treatment, SAPS II score, serum creatinine on ICU admission and sepsis were the independent risk factors for development of any stage of AKI. Among the Stage 3 patients (34) 50% received renal replacement therapy. The overall utilization of intermittent renal replacement therapy was high (64.8%). The overall in-hospital mortality rate of AKI was 49% (55/112). The ICU mortality rate was 39.3% (44/112). The independent risk factors for ICU mortality were age, mechanical ventilation, SOFA score and AKI Stage 3.ConclusionsFor the first time we have established the incidence of AKI using the AKIN criteria in Hungarian ICUs. Results of the present study confirm that AKI has a high incidence and is associated with high ICU and in-hospital mortality.

Enormous airway secretion after lung resection is common and can lead to dyspnea and radiological anomalies. Depending on the patient’s medical history, it can lead to heart failure, which appears in arrythmia or pulmonary edema. An inflammatory event with high level of proinflammatory cytokines can also lead to arrythmia. The stretch of the wall of vessels can also cause a cytokine release, and the thromboembolic event is a possible common cause of this stretch in the perioperative period.
