A short-cut review was carried out to establish whether the application of cricoid pressure during the induction of general anaesthesia reduced the incidence of regurgitation and aspiration of gastric contents. One good quality review article, two studies and two abstracts provided the best evidence to answer the clinical question. The authors, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated (table 1). It is concluded that although there is a theoretical advantage to providing cricoid pressure during induction, there is little evidence of any benefit at this time.

Is a watch and wait approach safe in asymptomatic patients presenting to the emergency department with a confirmed oesophageal coin on x-ray? ⋯ In the UK asymptomatic children, with no history of tracheal or oesophageal disease and a confirmed oesophageal coin on x-ray should undergo a period of observation up to 18 h. This can be safely undertaken at home, followed by a repeat x-ray in the emergency department.

The aim of this manikin study was to compare the efficiency between overlapping (OP) and adjacent thumb positions (AP) for cardiac compressions using the encircling method in infants. ⋯ Higher intrathoracic pressures were achieved by OP in this study. However, further studies are needed to validate these effects of overlapping thumbs technique in infant cardiopulmonary resuscitation, not manikin.

Serial multiple biomarkers in the assessment of suspected acute coronary syndrome: multiple infarct markers in chest pain (MIMIC) study.
To evaluate the accuracy of a 2-h serial multiple biomarker (SMB) protocol for exclusion of myocardial infarction (MI) in the Emergency Department. ⋯ SMB alone is not sufficiently sensitive to exclude MI. Combined with risk scoring, SMB appears to identify patients at lower risk. This requires prospective validation.
