Face Coverings, Aerosol Dispersion and Mitigation of Virus Transmission Risk.

The SARS-CoV-2 virus is primarily transmitted through virus-laden fluid particles ejected from the mouth of infected people. Face covers can mitigate the risk of virus transmission but their outward effectiveness is not fully ascertained. by using a background oriented schlieren technique, we aim to investigate the air flow ejected by a person while quietly and heavily breathing, while coughing, and with different face covers.

Survival from profound metabolic acidosis due to hypovolaemic shock. A world record?

This case describes the unexpected survival of an adult man who presented to the emergency department with hypovolaemic shock secondary to a splenic haemorrhage. Before surgery he had a pH 6.527, base excess (BE) -34.

Recovery from sedation with remifentanil and propofol, compared with morphine and midazolam, for reduction in anterior shoulder dislocation.

Objective: To compare recovery from sedation using remifentanil and propofol with our standard regimen of morphine and midazolam for closed reduction in shoulder dislocation in an ED.

Methods: We randomised 40 patients for closed shoulder reduction to receive either remifentanil and propofol (R&P) (20 patients) or morphine and midazolam (M&M) (20 patients). A suitably trained ED doctor gave the sedation.

Effect of an integrated care pathway on acute asthma/wheeze in children attending hospital: cluster randomized trial.

Objective: To determine whether an integrated care pathway (ICP) could improve care delivered to patients coming to an emergency department only or to patients who were subsequently admitted.

Study Design: Children (age, 2-16 years; n = 298) coming to the ED with acute asthma/wheeze, were randomized by using a cluster design to either standard care or care delivered by an ICP.

Results: Children discharged from the ED who received care with an ICP (n = 118) received more prednisolone (81%; standard, 63%; P = .

Is the 'LEMON' method an easily applied emergency airway assessment tool?

Objective: To assess whether the 'LEMON' method, devised by the developers of the US National Emergency Airway Management Course, is an easily applied airway assessment tool in patients undergoing treatment in the emergency department resuscitation room.

Methods: One hundred patients treated in the resuscitation room of a UK teaching hospital between June 2002 and January 2003 were assessed on criteria based on the 'LEMON' method.

Results: All seven criteria of the 'Look' section of the method could be adequately assessed.
