Randomized Controlled Trial Clinical TrialPreoperative alpha2-adrenergic receptor agonists prevent the deterioration of renal function after cardiac surgery: results of a randomized, controlled trial.
To evaluate the influence of the alpha2-adrenergic receptor agonist clonidine on creatinine clearance as a measure of renal function. ⋯ Preoperative treatment with clonidine (4 microgram/kilogram) prevents the deterioration of renal function after cardiac surgery. This effect might be due to clonidine-induced reduction in the sympathetic nervous system response to coronary artery bypass graft surgery.

Comparative StudyHand-held blood gas analyzer is accurate in the critical care setting.
To determine the accuracy of a new, portable battery-powered blood gas analyzer when used by nonlaboratory-trained clinicians in the critical care setting. ⋯ IRMA is accurate and reproducible when used in the clinical setting by nonlaboratory-trained individuals. Nonlaboratory-trained individuals can obtain laboratory results in the critical care setting comparable with the results obtained by trained laboratory technologists. Bedside laboratory testing decreases turnaround time compared with a near-patient laboratory.
