Welcome back to April's papers of the month.
We've got 3 papers this month that look to challenge our work up strategies for the critically unwell. First up we look at a paper on the Ottawa subarachnoid haemorrhage rule, specifically considering if we can decrease scanning in patients with a suspected SAH and what application of the rule might mean for our practice.
Next up we look at a paper that might shine some real doubt on the use of IO access in our patients in cardiac arrest.
Lastly we look at a validation paper for the PERC rule for those patients with a suspected pulmonary embolus and this paper brings about some interesting points on external validity
Once again we'd really encourage you to have a look at the papers yourself and we've love to hear any thoughts or feedback you have.
