Randomized Controlled Trial
Intravenous paracetamol versus morphine for renal colic in the emergency department: a randomised double-blind controlled trial.
To determine the analgesic efficacy and safety of intravenous single-dose paracetamol versus morphine in patients presenting to the emergency department with renal colic. ⋯ Intravenous paracetamol is effective in treating patients presenting with renal colic to the emergency department. CLINICAL TRIALS REGISTRATION NO: ClinicalTrials.gov ID number NCT01318187.

A short cut review was carried out to establish whether drinking fluids was better than not drinking fluids at preventing exercise associated abdominal pain (stitch) in runners. 112 papers were found using the reported searches, of which 2 presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that drinking fluids before running is associated with stitch.

A short cut review was carried out to establish whether leg crossing prevents transient loss of consciousness in patients known to have orthostatic hypotension. 9 papers presented the best evidence to answer the clinical question. The author, date and country of publication, patient group studied, study type, relevant outcomes, results and study weaknesses of these best papers are tabulated. It is concluded that leg crossing can help reduce the incidence of transient loss of consciousness in patients with orthostatic hypotension.

Randomized Controlled Trial
Randomised controlled crossover trial of the effect on PtCO2 of oxygen-driven versus air-driven nebulisers in severe chronic obstructive pulmonary disease.
The comparative safety of oxygen versus air-driven nebulised bronchodilators in patients with acute exacerbations of chronic obstructive pulmonary disease (COPD) is uncertain. A randomised controlled trial was performed to assess the effect on the arterial partial pressure of carbon dioxide of nebulised bronchodilator driven with oxygen versus air in stable severe COPD. ⋯ The study was registered on the Australian New Zealand Clinical Trials Registry (ACTRN12610000080022).

Randomized Controlled Trial
Accuracy of a feedback device for cardiopulmonary resuscitation on a dental chair.
Conflicting studies exist about the effectiveness of cardiopulmonary resuscitation (CPR) on a dental chair. In some situations, dental surgeons are obliged to perform CPR with the patient on the chair. Feedback devices are supposed to guide the compression depth in order to improve the quality of CPR, but some devices are based on an accelerometer that can theoretically report erroneous results because of the lack of rigidity of a dental chair. ⋯ This study indicates that feedback devices with accelerometer technology are not sufficiently reliable to ensure adequate chest compression on dental chairs.
