ABSTRACT
Background: COVID-19 continues to spread globally and results in additional challenges for perioperative management in parturients. The purpose of this study was to determine the incidence and identify associated factors for neuraxial anaesthesia-related hypotension in COVDI-19 parturients during caesarean delivery.Methods: We performed a multicenter case-control study at 3 medical institutions in Hubei province, China form 1th January to 30th May 2020. All ASA Physical Status II full termed pregnant women who received caesarean delivery under neuraxial anaesthesia were eligible for inclusion. The univariate analysis and binary logistic regression analysis were used to identified the independent predictors of neuraxial anaesthesia-related hypotension.Results: Present study included 102 COVID-19 parturients. The incidence of neuraxial anaesthesia-related hypotension was 58%. Maternal abnormal lymphocyte count (OR = 3.41, p = 0.03), full stomach (OR = 3.22, p = 0.04), baseline heart rate (OR = 1.04, p = 0.03), experience of anaesthetist (OR = 0.86, p = 0.02) and surgeon (OR = 0.76, p = 0.03), and combined spinal-epidural anaesthesia technique (OR = 3.27, p = 0.02) were associated with neuraxial anaesthesia-related hypotension. The area under the receiver operating characteristic curve achieved 0.83 which was significantly higher than 0.5 (p < 0.001). And the sensitivity, specificity and percentage correct were 75%, 79% and 75%, respectively. The Hosmer-Lemeshow test showed a good calibration of the model (H = 2.01, DF = 8, p = 0.98).Conclusions: Maternal abnormal lymphocyte count, full stomach, baseline heart rate, experience of anaesthetist and surgeon, and combined spinal-epidural anaesthesia technique were identified as the independent predictors of neuraxial anaesthesia-related hypotension.

COVID-19 , HypotensionABSTRACT
Coronavirus disease-2019 (COVID-19) has rapidly spread worldwide. High-flow nasal cannula therapy (HFNC) is a major oxygen supporting therapy for severely ill patients, but information regarding the timing of HFNC application is scarce, especially in elderly patients. We retrospectively analyzed the clinical data of 110 elderly patients ([≥]65 years) who received HFNC from Renmin Hospital of Wuhan University, People's Hospital of Xiantao City and Chinese Medicine Hospital of Shishou City in Hubei Province, China, and from Affiliated Hospital of Guangdong Medical University, People's Hospital of Yangjiang City, People's Hospital of Maoming City in Guangdong Province, China. Of the 110 patients, the median age was 71 years (IQR, 68-78) and 59.1% was male. Thirty-eight patients received HFNC when 200 mmHg < PO2/FiO2 [≤] 300 mmHg (early HFNC group), and 72 patients received HFNC treatment when 100 mmHg < PaO2/FiO2 [≤] 200 mmHg (late HFNC group). Compared with the late HFNC group, patients in the early HFNC group had a lower likelihood of developing severe ARDS, longer time from illness onset to severe ARDS and shorter duration of viral shedding after illness onset, as well as shorter lengths of ICU and hospital stay. Twenty-four patients died during hospitalization, of whom 22 deaths (30.6%) were in the late HFNC group and 2(5.3%) in the early HFNC group. It is concluded that the prognosis was better in severely ill elderly patients with COVID-19 receiving early compared to late HFNC. This suggests HFNC could be considered early in this disease process.

COVID-19 , Respiratory Distress SyndromeABSTRACT
Objective:To analyse the clinical features of COVID-19 parturients, and to compare anaesthetic regimen and clinical outcomes in parturients with or without COVID-19 undergoing cesarean delivery.Methods: Data were extracted from the electronic medical record of 3 medical institutions in Hubei Province, China, from June 1, 2019 to March 20, 2020 according to inclusion and exclusion criteria. After propensity score matching with demographics, the clinical and laboratory characteristics of parturients with or without COVID-19 were analysed. The anaesthetic regimen and clinical outcomes of themselves and their infants were compared in these two groups of parturients. Results: A total of 1,588 patients without SARS-CoV-2 infection undergoing cesarean delivery were retrospectively included. After achieving a balanced cohort through propensity score matching, 89 patients (COVID-19 group), who were diagnosed with COVID-19 by SARS-CoV-2 nucleic acid test and CT scan matched with 173 patients without COVID-19 (Control group). The SARS-CoV-2 infected parturients in the early stages of COVID-19 outbreak was much more than during the later stage. The main clinical characteristics of parturients with COVID-19 were fever (34.8%), cough (33.7%), an increased plasma CRP (52.8%) and a decreased lymphocyte counting (33.7%). A high rate of emergency and a high incidence of anaesthesia-related complications, such as pharyngalgia, multiple puncture, intraoperative hypotension, nausea, vomiting, vertigo and chills in the COVID-19 parturients. In addition, the parturients with COVID-19 had a long duration of operation and hospital stay, and an increased intraoperative oxytocin utilization and postoperative oxygen therapy. The newborns from the SARS-CoV-2 infected mothers, who received general anaesthesia, had a high risk of Apgar score [≤]8 at 1 and 5 minutes after delivery and a higher rate of neonatal intensive care unit (NICU) admission. Conclusions: Anaesthesia-related complications occur more frequently in the COVID-19 parturients and their newborns have a high risk of distress.
