Background: An outbreak of coronavirus disease 2019 (COVID-19) took place in Wuhan, China, by the end of 2019, and the disease continues to spread all over the world. The number of patients is increasing rapidly, a large number of infected patients is critically ill, and the mortality is high. However, information on COVID-19 patients is limited, and its clinical characteristics have not been fully studied. Objectives: To compare the performances of point-of-care lung ultrasound (LUS) and bedside chest X-ray in assessing the condition of COVID-19 patients with acute respiratory distress syndrome (ARDS). Methods: This observational study enrolled 42 COVID-19 patients with ARDS who were admitted to the Department of Critical Care Medicine of the Wuhan Union Hospital from February to April 2020. The point-of-care LUS characteristics of the COVID-19 patients with ARDS were summarized, and the performances of LUS and bedside chest X-ray in assessing the patient’s condition were compared. Results: Most of the 42 patients were elderly individuals with chronic clinical diseases. The proportion of patients older than 60 years old was 85.7%. All patients were given invasive mechanical ventilation; eight (19.0%) of them received venovenous extracorporeal membrane oxygenation support. LUS has evident advantages in detecting lung consolidation, patchy shadows, and pleural thickening, and pleural line changes in particular. The receiver operating characteristic analysis indicated that the sensitivity, Youden index, and kappa value for detecting COVID-19 patients with ARDS were higher for LUS than the chest X-ray. Conclusion: LUS has better diagnostic accuracy and sensitivity in COVID-19 patients with ARDS than the chest X-ray.

A 45-year-old man ingested 3000 mg of citalopram hydrobromide (2400 mg citalopram). He presented to the Emergency Department 2 hours post-ingestion with a pulse of 100 beats/min and blood pressure of 120/ 80 mmHg. His electrocardiogram (ECG) was normal. Chest X-ray showed bilateral shadowing, with no evidence of aspiration of gastric contents. Shortly after, he had three tonic-clonic seizures, requiring intravenous diazepam. Eight hours post-ingestion he became oliguric with deteriorating renal function, despite normal arterial and central venous pressures. He became increasingly hypoxic, with chest X-ray changes compatible with adult respiratory distress syndrome (ARDS). Despite treatment with 100% oxygen and continuous positive airway pressure, his gas exchange continued to deteriorate, requiring intubation and ventilation. His renal function also deteriorated with a peak creatinine of 492 mmol/L on day 4 in the absence of rhabdomyolysis. There was complete spontaneous recovery of renal function after 2 weeks. A peak plasma total citalopram (R-S enantiomers) concentration of 1.92 mg/L was recorded 2 hours post-ingestion. Total norcitalopram concentrations continued to rise up to 24 hours post-ingestion. Citalopram has been associated with seizures, ECG abnormalities, rhabdomyolysis and coma after overdose. The renal and respiratory complications seen in this patient have not been reported previously.

We report a 53-year-old man who ingested 2400 mg of citalopram and presented to the emergency department three hours post-ingestion with altered mental status, somnolence, and a blood pressure of 67/45 mmHg. He failed to respond to three boluses of normal saline (1000 ml each) and required vasopressors. The patient developed serotonin syndrome with hyper-reflexia, rigidity, and ankle myoclonus. He had a tonic-clonic seizure in the ER requiring intravenous lorazepam and phenytoin. An ECG showed QT prolongation. Chest x-ray on presentation was normal. Within 32 hours the patient developed acute respiratory distress, hypoxemia, a wide A-a gradient, PaO2/FiO2< 200, and chest x-ray changes compatible with acute respiratory distress syndrome (ARDS). He had normal central venous pressures, normal cardiac biomarkers, normal systolic and diastolic functions on echocardiography, and no acute ST/T wave changes. His ABG showed a metabolic acidosis and a respiratory acidosis. The patient required intubation and ventilation. Citalopram has been associated with seizures and ECG abnormalities after overdoses. The respiratory complications and metabolic acidosis have been reported only a few times in the literature.  We are reporting the second case of ARDS and the fifth case of metabolic acidosis due to citalopram overdose and suggest that the metabolic acidemia is explained by propionic acid. The respiratory acidosis seen in this patient has not been reported previously.

To the Editor.— Carlo et al1 report an "expert system" based on an algorithm for mechanical ventilation of infants with respiratory distress syndrome which would have corrected arterial blood gas derangements in 89% of 106 clinical trials. This algorithm was applied to additional trials using an independently designed computer-generated ventilation simulation program (VSP). Written in BASIC, VSP expects its user to manage a randomly "created" infant with respiratory distress syndrome by monitoring arterial blood gas values, physical examination findings, and chest x-ray film findings.2

A 64-year-old man was intubated and ventilated for COVID-19-associated acute respiratory distress syndrome. He had a background history of chronic obstructive pulmonary disease and ischaemic heart disease. His oxygen saturations dropped rapidly to 80% on day 9 of ICU admission. Chest auscultation revealed absent breath sounds over the left upper chest which raised suspicions for pneumothorax, of which a small stable left apical pneumothorax was documented on a recent CT scan of the thorax. Point-of-care ultrasonography was performed prior to attempting chest drain insertion which demonstrated sliding pleura on the left side (GE Healthcare model: Vscan Extend—display: 5 inches, 720×1280 pixels resolution, sector probe—broad bandwidth: 1.7–3.8 MHz, 24 cm penetration and linear probe—broad bandwidth: 3.3–8 MHz, 8 cm penetration). A portable chest X-ray was obtained which demonstrated left upper lobe collapse secondary to mucus plugging. The mucus plug was successfully suctioned from the patient’s airway using bedside bronchoscopy subsequently improving the patient’s oxygen saturation. A follow-up chest X-ray and CT scan of the thorax demonstrated interval resolution of the left upper lobe collapse. While expansion of his existing pneumothorax was first on the list of differential diagnoses, the use of ultrasonography early in the patient’s assessment ensured it was ruled out prior to attempting chest drain insertion, thus prompting the acquisition of the chest X-ray which subsequently demonstrated the left upper lobe collapse as the correct diagnosis.

Abstract Background Acute respiratory distress syndrome (ARDS) is multifactorial and can result from sepsis, trauma, or pneumonia, amongst other primary pathologies. It is one of the major causes of death in critically ill patients with a reported mortality rate up to 45%. The present study focuses on the development of a large animal model of smoke inhalation-induced ARDS in an effort to provide the scientific community with a reliable, reproducible large animal model of isolated toxic inhalation injury-induced ARDS. Methods Animals (n = 21) were exposed to smoke under general anesthesia for 1 to 2 h (median smoke exposure = 0.5 to 1 L of oak wood smoke) after the ultrasound-guided placement of carotid, pulmonary, and femoral artery catheters. Peripheral oxygen saturation (SpO2), vital signs, and ventilator parameters were monitored throughout the procedure. Chest x-ray, carotid, femoral and pulmonary artery blood samples were collected before, during, and after smoke exposure. Animals were euthanized and lung tissue collected for analysis 48 h after smoke inhalation. Results Animals developed ARDS 48 h after smoke inhalation as reflected by a decrease in SpO2 by approximately 31%, PaO2/FiO2 ratio by approximately 208 (50%), and development of bilateral, diffuse infiltrates on chest x-ray. Study animals also demonstrated a significant increase in IL-6 level, lung tissue injury score and wet/dry ratio, as well as changes in other arterial blood gas (ABG) parameters. Conclusions This study reports, for the first time, a novel large animal model of isolated smoke inhalation-induced ARDS without confounding variables such as cutaneous burn injury. Use of this unique model may be of benefit in studying the pathophysiology of inhalation injury or for development of novel therapeutics.

Exogenous surfactant administration is currently being tested in patients with the acute respiratory distress syndrome (ARDS). The results of the studies have varied because several factors may influence the host’s response to this therapy. This clinical pilot study was designed to evaluate the safety and efficacy of exogenous surfactant administration in pediatric patients with ARDS. Surfactant was administered to 13 patients with severe lung dysfunction, and eight of these patients experienced a significant improvement in oxygenation after the first dose of surfactant. In these patients the exogenous surfactant was administered within 48 h of the diagnosis of ARDS, whereas in the five patients who did not respond, surfactant was administered several days after the onset of ARDS. Responders also spent fewer days on a mechanical ventilator and less time in intensive care compared with nonresponders. Based on the results of this pilot study, a more appropriate multicentre clinical trial should be designed to evaluate this treatment strategy.
