Randomized Controlled Trial
Determination of the appropriate sizes of oropharyngeal airways in adults: correlation with external facial measurements: A randomised crossover study.
Two external facial measurements have been recommended as reference criteria for estimating appropriate oropharyngeal airway sizes: the distances between the maxillary incisors to the angle of the mandible, and that from the corner of the mouth to the angle of the mandible. ⋯ With regard to adequate ventilation in conjunction with an acceptable endoscopic view, an oropharyngeal airway whose size is based upon the distance from the maxillary incisors to the angle of the mandible is more advantageous than if based upon the distance from the corner of the mouth to the angle of the mandible.

Observational Study
Rhabdomyolysis and acute kidney injury: creatine kinase as a prognostic marker and validation of the McMahon Score in a 10-year cohort: A retrospective observational evaluation.
High-volume fluid resuscitation and the administration of sodium bicarbonate and diuretics have a theoretical renoprotective role in patients at high risk of acute kidney injury (AKI) following rhabdomyolysis. Abnormally elevated creatine kinase has previously been used as a biological marker for the identification of patients at high risk of AKI following rhabdomyolysis. ⋯ Creatine kinase is not a specific or early predictor of AKI in patients with rhabdomyolysis. Although a PEAK creatine kinase of at least 5000 Ul has sensitivity acceptable for screening purposes, this is often a delayed finding. A McMahon score of at least 6 calculated on admission allows for a more sensitive, specific and timely identification of patients who may benefit from high-volume fluid resuscitation.
