Gastrointestinal symptoms and liver injury of COVID-19

COVID-19 is caused by the SARS-COV-2, which characterized with typical respiratory symptoms. In addition to the respiratory system injury, SARS-COV-2 may also invade other organs that express the cell surface receptor ACE2. Digestive system is a susceptible target of SARS-COV-2. Most patients show clinical symptoms of impaired digestive system during the course of the disease. Gastrointestinal symptoms of COVID-19 include anorexia, nausea, vomiting, diarrhea, abdominal pain, and liver damage. Patients with abnormal symptoms of the digestive system have a greater chance of progressing to severe or critical illness, a worse prognosis, and a higher risk of death. This paper aims to discuss the digestive symptoms of COVID-19 infection, so as to improve the attention to the digestive system abnormalities and gastrointestinal symptoms of COVID-19 patients during clinical diagnosis, treatment and prevention and control.

Comparison of the clinical characteristics and mortalities of severe COVID-19 patients between pre- and post-menopause women and age-matched men.

The mortality rate of young female COVID-19 patients is reported to be lower than that of young males but no significant difference in mortality was found between female and male COVID-19 patients aged over 65 years, and the underlying mechanism is unknown. We retrospectively analyzed clinical characteristics and outcomes of severely ill pre- and post-menopausal COVID-19 patients and compared with age-matched males. Of the 459 patients included, 141 aged ≤55, among whom 19 died (16 males vs. 3 females, p<0.005). While for patients >55 years (n=318), 115 died (47 females vs. 68 males, p=0.149). In patients ≤55 years old, the levels of NLR, median LDH, median c-reactive protein and procalcitonin were significantly higher while the median lymphocyte count and LCR were lower in male than in female (all p<0.0001). In patients over 55, these biochemical parameters were far away from related normal/reference values in the vast majority of these patients in both genders which were in contrast to that seen in the young group. It is concluded that the mortality of severely ill pre-menopausal but not post-menopausal COVID-19 female patients is lower than age-matched male. Our findings support the notion that estrogen plays a beneficial role in combating COVID-19.

Chinese Society of Anesthesiology expert consensus on anesthetic management of cardiac surgical patients with suspected or confirmed Coronavirus disease 2019

The outbreak of a new coronavirus (severe acute respiratory syndrome coronavirus 2 [SARS-CoV-2]) in China in December 2019 has brought serious challenges to disease prevention and public health. Patients with severe coronavirus disease 2019 (COVID-19) who undergo cardiovascular surgery necessitate extremely high demands from anesthesia personnel, and face high risks of mortality and morbidity. Based on the current understanding of COVID-19 and the clinical characteristics of cardiovascular surgical patients, the authors provide anesthesia management guidelines for cardiovascular surgery along with the prevention and control of COVID-19.

The Risk of Neuraxial Anesthesia-Related Hypotension in COVID-19 Parturients Undergoing Cesarean Delivery: A Multicenter, Retrospective, Propensity Score Matched Cohort Study.

Background: SARS-CoV-2 infection was referred to sympathetic hyperactivity, which might increase the susceptibility of neuraxial anesthesia-related hypotension resulted from sympathetic inhibition. We conducted a multicenter, retrospective, propensity score matched (PSM) cohort study to determine whether COVID-19 parturients have an increased risk of hypotension after neuraxial anesthesia for cesarean delivery. Methods: Clinical data of COVID-19 parturients were collected from the electronic medical records from 1th January to 31th May, 2020 in three hospitals of Hubei Province, China. Information of Control parturients (without COVID-19) were obtained at the same institutions over a similar period in 2019. All American Society of Anaesthesiologists (ASA) Physical Status II full termed pregnant women who received cesarean delivery under neuraxial anesthesia were included. The primary objective was to obtain and compare the incidence of neuraxial anesthesia-related hypotension. Secondary objectives were the analysis of anesthetic implementation and administration, intraoperative maternal vital signs and adverse reactions, and neonatal Apgar scores at 1 and 5 min after delivery. The clinical characteristics of COVID-19 parturients were also analyzed. PSM was derived to balance the predictors for neuraxial anesthesia-related hypotension based on previous studies. Results: In present study, 101 COVID-19 parturients and 186 Control parturients were derived from 1,403 cases referenced to propensity score matching. The incidence of neuraxial anesthesia-related hypotension was 57.4% in COVID-19 parturients and 41.9% in Control parturients with an incidence risk ratio (IRR) of 1.37 (95% CI 1.08-1.74; P = 0.012; post-hoc Cramér's V = 0.15) in the PSM cohort. The incidences of nausea, vomiting, dizziness, and shaking were significantly higher in the COVID-19 group than Control group (48.5 vs. 17.2%, P < 0.001; 10.9 vs. 4.3%, P = 0.03; 18.8 vs. 3.2%, P < 0.001; 51.5 vs. 18.3%, P < 0.001; respectively). The Apgar scores at 1 min was significantly lower in newborns from COVID-19 parturients than that in Control babies (P = 0.04). Conclusions: An increased risk of neuraxial anesthesia-related hypotension in COVID-19 parturients undergoing cesarean delivery should be stressed.

First known case of successful pressure ulcer treatment in a lung transplant patient with post-COVID-19 pneumonia.

Given the current COVID-19 crisis, multiple clinical manifestations and related complications of COVID-19 disease, especially in lung transplant patients following post-COVID-19 pneumonia, are a major challenge. Herein, we report the therapeutic course of the first reported case of sacrococcyx pressure ulcers (PU) in a 65-year-old male COVID-19 patient who underwent lung transplantation and developed a PU following surgery. We used a combination of regulated negative pressure-assisted wound therapy system (RNPT, six treatment courses, five days per treatment course), a skin tension-relief system (an intraoperative aid in minimising wounds caused by sacrococcygeal PUs) and a gluteus maximus myocutaneous flap to repair sacrococcygeal wounds. This successfully treated case provides a reference point for the treatment of similar cases.

Course of illness and outcomes in older COVID-19 patients treated with HFNC: a retrospective analysis.

Coronavirus disease-2019 (COVID-19) has rapidly spread worldwide and causes high mortality of elderly patients. High-flow nasal cannula therapy (HFNC) is an oxygen delivery method for severely ill patients. We retrospectively analyzed the course of illness and outcomes in 110 elderly COVID-19 patients (≥65 years) treated with HFNC from 6 hospitals. 38 patients received HFNC (200 mmHg < PaO2/FiO2 ≤ 300 mmHg, early HFNC group), and 72 patients received HFNC (100 mmHg < PaO2/FiO2 ≤ 200 mmHg, late HFNC group). There were no significant differences of sequential organ failure assessment (SOFA) scores and APECH II scores between early and late HFNC group on admission. Compared with the late HFNC group, patients in the early HFNC group had a lower likelihood of developing severe acute respiratory distress syndrome (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. 24 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. The present study suggested that the outcomes were better in severely ill elderly patients with COVID-19 receiving early compared to late HFNC.

Gastrointestinal Symptoms Associated With Unfavorable Prognosis of COVID-19 Patients: A Retrospective Study.

Background and Aim: The global pandemic of COVID-19 has posed an enormous threat to the economy and people's lives across various countries. Patients with COVID-19 most commonly present with respiratory symptoms. However, gastrointestinal (GI) symptoms can also occur. We aimed to study the relationship between GI symptoms and disease prognosis in patients with COVID-19. Methods: In a single-center and retrospective cohort study, the outcomes in COVID-19 patients with or without GI symptoms were compared. The propensity score is a conditional probability of having a particular exposure (COVID-19 patients with GI symptoms vs. without GI symptoms) given a set of baseline measured covariates. Survival was estimated using the Kaplan-Meier method, and any differences in survival were evaluated with a stratified log-rank-test. To explore the GI symptoms associated with ARDS, non-invasive ventilator treatment, tracheal intubation, tracheotomy, and CRRT, univariable and multivariable COX regression models were used. Results: Among 1,113 eligible patients, 359 patients with GI symptoms and 718 without GI symptoms had similar propensity scores and were included in the analyses. Patients with GI symptoms, as compared with those without GI symptoms, were associated with a similar risk of death, but with higher risks of ARDS, non-invasive mechanical ventilation in COVID-19 patients, respectively. Conclusions: The presence of GI symptoms was associated with a high risk of ARDS, non-invasive mechanical ventilation and tracheal intubation in patients with COVID-19 but not mortality.

Sex differences in clinical characteristics and risk factors for mortality among severe patients with COVID-19: a retrospective study.

The coronavirus disease 2019 (COVID-19) became a global pandemic. Males, compared to females, seem to be more susceptible to COVID-19, but related evidence is scarce, especially in severe patients. We explored sex differences in clinical characteristics and potential risk factors for mortality in severe COVID-19 patients. In this retrospective cohort study, we included all severe COVID-19 patients admitted to Eastern Renmin Hospital of Wuhan University, Wuhan, China, with a definitive clinical outcome as of Apr 10, 2020. Of the included 651 patients, 332 were male, and 319 were female. Males and females did not differ in age and underlying comorbidities. Males were more likely than females to report fever and develop serious complications, including acute respiratory distress syndrome, secondary infection, acute cardiac injury, coagulopathy, acute kidney injury and arrhythmia. Further, males had much higher mortality relative to females. Multivariable regression showed neutrophilia (odds ratio 6.845, 95% CI 1.227-38.192, p=0.028), thrombocytopenia (19.488, 3.030-25.335, p=0.002), hypersensitive troponin I greater than 0.04 pg/mL (6.058, 1.545-23.755, p=0.010), and procalcitonin greater than 0.1 ng/mL (6.350, 1.396-28.882, p=0.017) on admission were associated with in-hospital death. With either of these risk factors, the cumulative survival rate was relatively lower in males than in females. In conclusion, males are more likely than females to develop serious complications and progress to death. The potential risk factors of neutrophilia, thrombocytopenia, hypersensitive troponin I greater than 0.04 pg/mL and procalcitonin more than 0.1 ng/mL may help clinicians to identify patients with poor outcomes at an early stage, especially in males.

Safety and efficacy of different anesthetic regimens for parturients with COVID-19 undergoing Cesarean delivery: a case series of 17 patients.

PURPOSE: To assess the management and safety of epidural or general anesthesia for Cesarean delivery in parturients with coronavirus disease (COVID-19) and their newborns, and to evaluate the standardized procedures for protecting medical staff. METHODS: We retrospectively reviewed the cases of parturients diagnosed with severe acute respiratory syndrome coronavirus (SARS-CoV-2) infection disease (COVID-19). Their epidemiologic history, chest computed tomography scans, laboratory measurements, and SARS-CoV-2 nucleic acid positivity were evaluated. We also recorded the patients' demographic and clinical characteristics, anesthesia and surgery-related data, maternal and neonatal complications, as well as the health status of the involved medical staff. RESULTS: The clinical characteristics of 17 pregnant women infected with SARS-CoV-2 were similar to those previously reported in non-pregnant adult patients. All of the 17 patients underwent Cesarean delivery with anesthesia performed according to standardized anesthesia/surgery procedures. Fourteen of the patients underwent continuous epidural anesthesia with 12 experiencing significant intraoperative hypotension. Three patients received general anesthesia with tracheal intubation because emergency surgery was needed. Three of the parturients are still recovering from their Cesarean delivery and are receiving in-hospital treatment for COVID-19. Three neonates were born prematurely. There were no deaths or serious neonatal asphyxia events. All neonatal SARS-CoV-2 nucleic acid tests were negative. No medical staff were infected throughout the patient care period. CONCLUSIONS: Both epidural and general anesthesia were safely used for Cesarean delivery in the parturients with COVID-19. Nevertheless, the incidence of hypotension during epidural anesthesia appeared excessive. Proper patient transfer, medical staff access procedures, and effective biosafety precautions are important to protect medical staff from COVID-19.

RéSUMé: OBJECTIF: Évaluer la gestion et la sécurité de l'anesthésie péridurale ou de l'anesthésie générale pour un accouchement par césarienne chez des parturientes infectées par la maladie à coronavirus 2019 (COVID-19) et pour leurs nouveau-nés, et évaluer les procédures standardisées visant la protection du personnel médical. MéTHODES: Nous avons revu de manière rétrospective les cas de parturientes ayant un diagnostic de syndrome respiratoire aigu sévère lié à l'infection (SARS-CoV-2) par le coronavirus (COVID-19). L'enquête épidémiologique, leurs examens de tomodensitométrie thoracique, les analyses de laboratoire et leur positivité pour l'acide nucléique du SARS-CoV-2 ont été évalués. Nous avons également consigné les caractéristiques démographiques et cliniques des patientes, les données liées à l'anesthésie et à la chirurgie, les complications maternelles et néonatales, ainsi que l'état de santé du personnel médical concerné. RéSULTATS: Les caractéristiques cliniques des 17 femmes enceintes infectées par le SARS-CoV-2 étaient semblables à celles précédemment rapportées chez des patientes adultes non enceintes. Les 17 patientes ont subi un accouchement par césarienne sous anesthésie effectué selon les procédures standardisées d'anesthésie et de chirurgie. Parmi les quatorze patientes ayant eu une anesthésie péridurale continue, 12 patientes ont présenté une hypotension peropératoire significative. Trois patientes ont accouché sous anesthésie générale avec intubation trachéale, car nécessitant une chirurgie d'urgence. Trois parturientes sont encore en convalescence après leur accouchement par césarienne et reçoivent un traitement à l'hôpital pour la COVID-19. Trois nouveau-nés sont nés prématurément. Il n'y a pas eu de décès ou d'événement asphyxique néonatal grave. Toutes les recherches d'acide nucléique du SARS-CoV-2 chez les nouveau-nés ont été négatives. Aucun membre du personnel médical n'a été infecté pendant la durée des soins aux patientes. CONCLUSIONS: L'anesthésie par péridurale et l'anesthésie générale ont été utilisées sans danger pour l'accouchement par césarienne de parturientes atteintes de COVID-19. Cependant, l'incidence de l'hypotension au cours de l'anesthésie péridurale a paru excessive. Un transfert approprié des patientes, les procédures d'accès du personnel médical et des précautions efficaces de biosécurité sont importants pour protéger le personnel médical contre la COVID-19.

Decreased complement C3 levels are associated with poor prognosis in patients with COVID-19: A retrospective cohort study.

OBJECTIVES: To describe the humoral immune feature of patients with coronavirus disease 2019 (COVID-19). METHODS: The levels of total immunoglobulins (IgG, IgM, IgA, and IgE), complement (C3, C4) results were retrospectively analyzed in COVID-19 patients. Univariable and multivariable logistic regression were performed to explore the risk factors associated with the in-hospital death. RESULT: A total of 236 patients were enrolled in this study, of which 169 were transferred to another institution or discharged (survival group) and 67 died in hospital (non-survival group). Compared with survivors, the levels of IgA and IgE in non-survivors increased significantly, and level of complement C3 decreased. Non-survivors also showed higher incidence of chest tightness, breath shortness and dyspnoea; higher levels of inflammatory indicators, leukocytes and neutrophils; and low levels of lymphocyte subsets. Multivariable regression showed increasing odds of in-hospital death associated with older age (HR: 1.099; 95%CI: 1.057-1.143; p < 0.0001), d-dimer greater (HR: 1.294; 95%CI: 1.138-1.473; p < 0.0001) and decreased complement C3 level (HR: 0.073; 95%CI: 0.007-0.722; p = 0.025) on admission. Finally, in survival COVID-19 patients whose humoral immunity was re-examined, C3 levels tended to increase, while in non-survivors it decreased. CONCLUSION: Low level of complement C3 may be an alert to the admitted COVID-19 patients with additional management. Inhibition of the complement pathway might be an effective therapeutic to COVID-19 patients.

Meta-analysis of coagulation parameters associated with disease severity and poor prognosis of COVID-19.

BACKGROUND: To determine whether abnormal coagulation parameters are associated with disease severity and poor prognosis in patients with 2019 Corona Virus Disease (COVID-19). METHODS: A systematic literature search was conducted using the databases PubMed, Embase, and Web of sciences until April 25, 2020. We included a total of 15 studies with 2277 patients. Platelet count (PLT), prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer (D-D), and fibrinogen (FIB) were collected and analyzed. The statistical results were expressed as the effect measured by mean difference (MD) with the related 95% confidence interval (CI). RESULTS: The PLT level of severe cases was lower than that of mild cases, while the levels of PT, D-D, and FIB were higher than those of mild cases (P < 0.05). The level of APTT had no statistical difference between two groups (P > 0.05). PT of ICU patients was significantly longer (P < 0.05) than that of non-ICU patients. In non-survivors, PT and D-D were higher, yet PLT was lower than that of survivors (P < 0.05). There was no significant difference in APTT between survivors and non-survivors (P > 0.05). The funnel plot and Egger's regression test demonstrated that there was no publication bias. CONCLUSIONS: Our data support the notion that coagulopathy could be considered as a risk factor for disease severity and mortality of COVID-19, which may help clinicians to identify the incidence of poor outcomes in COVID-19 patients.

COVID-19 infection, a potential threat to surgical patients and staff? A retrospective cohort study.

BACKGROUND: This study aimed to describe the epidemiologic and clinical characteristics of coronavirus disease 2019 (COVID-19) in surgical patients and medical staff. METHODS: A single-center case series of 1586 consecutive surgical patients was selected at our hospital from January 13 to March 12, 2020. The epidemiological and clinical characteristics of COVID-19 were analyzed and followed up to May 20, 2020. The transmission of COVID-19 between the surgical patients and medical staff was also recorded. RESULTS: Seventeen (1.07%) surgical patients were diagnosed with COVID-19, with a high incidence in the thoracic department (9.37%), and the median age was 58 years (IQR, 53-73). The median time from hospital admission to COVID-19 diagnosis was 9.0 days (7.0-12.0) and was 6.0 days (4.0-7.0) from the day of surgery to COVID-19 diagnosis. Eleven (64.70%) patients suffered from pulmonary infection before surgery. When COVID-19 was diagnosed, common symptoms were fever (82.35%) and cough (94.12%), and most (82.35%) neutrophil/lymphocyte ratios were high (>3.5). Chest computed tomography (CT) (82.35%) showed bilateral dense shadows. Surgical patients with COVID-19 stayed in the hospital for approximately 35.0 days (25.5-43.0), with a mortality rate of 11.76%. Sixteen medical staff were infected with COVID-19 in the early stage. CONCLUSIONS: In this series of 1586 surgical patients, the COVID-19 infection rate was 1.07%, with an especially high incidence among patients with thoracic diseases. Middle-aged and elderly patients with preoperative pulmonary infection were more susceptible to COVID-19 infection after surgery. Medical staff were infected with COVID-19 and should take protective measures to protect themselves.

Changes in the Clinical Characteristics of 62 Patients Who Died from Coronavirus Disease 2019.

BACKGROUND: Since the first reports of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infections in December 2019 in Wuhan, China, the virus has spread to other parts of China and across the world. Although a few studies have assessed the clinical course of coronavirus disease 2019 (COVID-19), the changes in clinical characteristics during disease progression remain unclear. METHODS: We retrospectively analyzed the clinical characteristics of 62 patients who died from COVID-19 at the Central Hospital of Wuhan between January 26 and February 17, 2020. We compared the clinical features on admission and at the last follow-up before death. RESULTS: Of the 62 patients with COVID-19, 41 (66%) patients were male, and 21 (34%) were female. The median age was 72 years (interquartile range (IQR), 54-88), and 45 (72.5%) patients had preexisting conditions. The median time from symptom onset to the first visit at the clinic was three days, while the median time from symptom onset to death was 18.5 days. During disease progression, the amounts of arterial gases worsened, and liver, renal, and heart dysfunction was observed. Due to the cytokine storm, infection-related biomarkers, including lactic acid, C-reactive protein, and interleukine-6, gradually worsened during hospitalization. CONCLUSION: Our findings suggest that during hospitalization, many COVID-19 patients experienced multiple organ dysfunction and cytokine storm. The time from symptom onset to death was only 18.5 days, highlighting the disease's rapid progression. The better understanding of the clinical changes during disease progression might provide further insight into the COVID-19 pathophysiology.

Sleep Disturbance and Psychological Profiles of Medical Staff and Non-Medical Staff During the Early Outbreak of COVID-19 in Hubei Province, China.

OBJECTIVE: The outbreak of coronavirus disease 2019 (COVID-19) has considerably burdened the healthcare system in the Hubei Province, the most severely affected region in China. The aim of our study was to assess the psychological effects of COVID-19 epidemic on the healthcare workers in Hubei. METHODS: A total of 2737 healthcare workers were sampled using a two-dimensional code shared online between Mar 4 and Mar 9, 2020. The questionnaires consisted of three elements: baseline characteristics, Pittsburgh Sleep Quality Index (PSQI), and Hospital Anxiety and Depression Scale (HADS). The primary outcome variables were PQSI, anxiety and depression scores of non-medical staff, non-frontline medical staff and frontline medical staff. Binary logistical regression analyses were used to compare between respondents with and without sleep disturbance. RESULTS: About 61.6% of the respondents reported sleep problems, 22.6% experienced anxiety, and 35% exhibited depressive symptoms. The prevalence of sleep disorders was higher among the frontline healthcare workers compared to the non-frontline and non-medical staff, while anxiety and depression were prevalent in the entire cohort. Logistic regression analysis identified medical occupation, family burden, bereavement, anxiety, and depression as significantly predictive of poor sleep quality. CONCLUSIONS: Frontline medical staff are more vulnerable to sleep disturbances. Psychosocial interventions are needed to help allied healthcare personnel to better respond to COVID-19 and future outbreaks.

Acquired infection after intubating patients with COVID-19: Datasets.

Thirty-six anesthesia departments in 36 hospitals in four provinces of China where an outbreak of COVID-19 occurred were surveyed. We found that there were ten anesthesiologists (5 male and 5 female) who contracted the infection after performing intubation, as well as 4 nurses (1 male and 3 female) who contracted the infection after assisting with the intubation. This is a retrospective investigation and no intervention was applied. The numbers are presented as mean ± Standard Deviation (SD). We used Graphpad Prism (version 8.2.1 Windows version, GraphPad Software, San Diego). Fisher's exact test at a two-sided significance level of 0.05 was used to identify potential risk factor (s) for intubation providers. A P value less than 0.05 is considered statistically significant. A total of 211 anesthesiologists from four provinces were involved in the intubation of 664 patients with confirmed or potential COVID-19. Of these 644 patients, 640 cases were eventually confirmed with a diagnosis of COVID-19. Among the 211 anesthesiologists who performed intubation, 10 of them had a confirmed diagnosis of COVID-19 afterwards. Coughing is a risk factor for provider infection (P = 0.0001). The number of intubation attempts (within three attempts) did not increase the risk of the infection. All of the affected anesthesiologists had symptoms 2-12 days after the intubation encounter (average 6 ±â€¯3 days). All had radiological image evidence of bilateral pneumonia and all reported relatively mild symptoms. The affected doctors were out of clinical service for 20-60 days (average 46 ±â€¯12 days). Seven of the doctors have been discharged from the hospital, but three of them remain hospitalized. Four nurses who assisted with intubations contracted COVID-19. One of these nurses was in critical condition but was eventually discharged with a loss of 50 days of clinical service. The remaining three nurses have had mild symptoms so far, but one is still hospitalized.

Avoiding health worker infection and containing the coronavirus disease 2019 pandemic: Perspectives from the frontline in Wuhan.

Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), has caused great public concern worldwide due to its high rates of infectivity and pathogenicity. The Chinese government responded in a timely manner, alleviated the dilemma, achieved a huge victory and lockdown has now been lifted in Wuhan. However, the outbreak has occurred in more than 200 other countries. Globally, as of 9:56 am CEST on 19 May 2020, there have been 4,696,849 confirmed cases of COVID-19, including 315,131 deaths, reported to Word Health Organization (WHO). The spread of COVID-19 overwhelmed the healthcare systems of many countries and even crashed the fragile healthcare systems of some. Although the situation in each country is different, health workers play a critical role in the fight against COVID-19. In this review, we highlight the status of health worker infections in China and other countries, especially the causes of infection in China and the standardised protocol to protect health workers from the perspective of an anaesthesiologist, in the hope of providing references to reduce medical infections and contain the COVID-19 epidemic.

Clinical characteristics and outcomes of patients undergoing surgeries during the incubation period of COVID-19 infection.

BACKGROUND: The outbreak of 2019 novel coronavirus disease (COVID-19) in Wuhan, China, has spread rapidly worldwide. In the early stage, we encountered a small but meaningful number of patients who were unintentionally scheduled for elective surgeries during the incubation period of COVID-19. We intended to describe their clinical characteristics and outcomes. METHODS: We retrospectively analyzed the clinical data of 34 patients underwent elective surgeries during the incubation period of COVID-19 at Renmin Hospital, Zhongnan Hospital, Tongji Hospital and Central Hospital in Wuhan, from January 1 to February 5, 2020. FINDINGS: Of the 34 operative patients, the median age was 55 years (IQR, 43-63), and 20 (58·8%) patients were women. All patients developed COVID-19 pneumonia shortly after surgery with abnormal findings on chest computed tomographic scans. Common symptoms included fever (31 [91·2%]), fatigue (25 [73·5%]) and dry cough (18 [52·9%]). 15 (44·1%) patients required admission to intensive care unit (ICU) during disease progression, and 7 patients (20·5%) died after admission to ICU. Compared with non-ICU patients, ICU patients were older, were more likely to have underlying comorbidities, underwent more difficult surgeries, as well as more severe laboratory abnormalities (eg, hyperleukocytemia, lymphopenia). The most common complications in non-survivors included ARDS, shock, arrhythmia and acute cardiac injury. INTERPRETATION: In this retrospective cohort study of 34 operative patients with confirmed COVID-19, 15 (44·1%) patients needed ICU care, and the mortality rate was 20·5%.
