Randomized Controlled Trial Comparative StudyUltrasonography-guided radial artery catheterization is superior compared with the traditional palpation technique: A prospective, randomized, blinded, crossover study.
Radial artery catheterization is gaining popularity for diagnostic and interventional procedures. Palpation technique is widely used for the procedure, but ultrasonography has been shown to increase catheterization success. A recently described ultrasonography technique is termed 'dynamic needle tip positioning'. We aimed to compare the traditional palpation technique and dynamic needle tip positioning technique in regard to clinically relevant end points. ⋯ Ultrasonography guidance using the dynamic needle tip positioning technique for radial artery catheterization significantly improves clinically relevant aspects of the procedure.

Medical emergency team activation: performance of conventional dichotomised criteria versus national early warning score.
To activate the hospital's medical emergency team (MET), either conventional dichotomised activation criteria or an early warning scoring system may be used. The relative performance of these different activation patterns to discriminate high risk patients in a heterogenic general ward population after adjustment for multiple confounding factors has not been evaluated. We aimed to evaluate the dichotomised activation criteria used at our institution and the recently published national early warning score (NEWS, United Kingdom). ⋯ NEWS discriminates high risk patients in a heterogenic general ward population independently of multiple confounding factors. The conventional dichotomised activation criteria were not able to detect high risk patients.

Randomized Controlled TrialMyocardial protection by remote ischaemic pre-conditioning is abolished in sulphonylurea-treated diabetics undergoing coronary revascularisation.
Remote ischaemic pre-conditioning attenuates myocardial injury. Because sulphonylurea drugs interfere with ischaemic and anaesthetic pre-conditioning, we assessed whether remote ischaemic pre-conditioning effects are altered in sulphonylurea-treated diabetics. ⋯ Cardioprotection by remote ischaemic pre-conditioning during isoflurane anaesthesia is abolished in sulphonylurea-treated diabetics.
