Introduction: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) has presented health-care systems worldwide with novel challenges and experiences and evidence is emerging during the pandemic. Patients requiring hospitalization frequently suffer from respiratory failure of different severities. Aim: The aim of this guideline is the treatment of patients with SARS CoV-2 (COVID-19) in hospital; in particular, it addresses the treatment of respiratory failure treated in general Internal Medical-and Pulmonary Medical wards. Results: Elderly patients and patients with chronic disease are particularly vulnerable to COVID-19. Target oxygen saturation should be between 92% and 96% in patients without chronic lung diseases. Treatment with >5 L oxygen/min should be in close collaboration with intensive care colleagues and >15 l/min preferably in intensive care units. High-flow nasal canula (HFNC) and long-term Continuous Positive Airway Pressure (CPAP) are recommended for patients not responding to conventional oxygen therapy. Non-invasive ventilation (NIV) is only recommended for selected patients, such as those with a ceiling of treatment or patients presenting with hypercapnic failure. With the use of humidification protective equipment as FFP2-3 masks should be used. Nebulized medication should be avoided, and spacers should be used instead. Conclusion: Respiratory failure is frequently the cause of hospitalization in patients with COVID-19 and should be monitored closely.
We describe characteristics and risk factors regarding pregnancy outcome in women with a preconception body mass index (BMI) >50 kg/m2 compared with women with BMI ≤50 kg/m2 in a retrospective population cohort study in singleton pregnancies from the Danish Medical Birth Registry. Results were analyzed as relative risks by a two‐proportion z‐test. Women with preconception BMI >50 kg/m2 smoked, developed gestational diabetes and pre‐eclampsia, and needed induction of labor more frequently than mothers with BMI ≤50 kg/m2. Examination of the case records showed that many attempted vaginal delivery without epidural analgesia, 21% needed an emergency cesarean section (compared with 12% among women with BMI ≤50 kg/m2), and 25% underwent general anesthesia in this context. Many neonates were macrosomic and 34% needed neonatal intensive care and early feeding compared with 6% of neonates from women with BMI ≤50 kg/m2. Women with an extremely high preconception BMI develop more pregnancy complications and their neonates appear affected by this as well.
Patients admitted to hospital with coronavirus disease 2019 (COVID-19) may develop acute respiratory failure (ARF) with compromised gas exchange. These patients require oxygen and possibly ventilatory support, which can be delivered via different devices. Initially, oxygen therapy will often be administered through a conventional binasal oxygen catheter or air-entrainment mask. However, when higher rates of oxygen flow are needed, patients are often stepped up to high-flow nasal cannula oxygen therapy (HFNC), continuous positive airway pressure (CPAP), bilevel positive airway pressure (BiPAP), or invasive mechanical ventilation (IMV). BiPAP, CPAP, and HFNC may be beneficial alternatives to IMV for COVID-19-associated ARF. Current evidence suggests that when nasal catheter oxygen therapy is insufficient for adequate oxygenation of patients with COVID-19-associated ARF, CPAP should be provided for prolonged periods. Subsequent escalation to IMV may be implemented if necessary.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
