Randomized Controlled TrialA Novel Blood-Sparing Agent in Cardiac Surgery? First In-Patient Experience with the Synthetic Serine Protease Inhibitor MDCO-2010: A Phase II, Randomized, Double-Blind, Placebo-Controlled Study in Patients Undergoing Coronary Artery Bypass Grafting with Cardiopulmonary Bypass.
Antifibrinolytics have been used for 2 decades to reduce bleeding in cardiac surgery. MDCO-2010 is a novel, synthetic, serine protease inhibitor. We describe the first experience with this drug in patients. ⋯ This first-in-patient study demonstrated dosage-proportional PK for MDCO-2010 and reduction of chest tube drainage and transfusions in patients undergoing primary coronary artery bypass grafting. Antifibrinolytic and anticoagulant effects were demonstrated using various markers of coagulation. MDCO-2010 was well tolerated and showed an acceptable initial safety profile. Larger multi-institutional studies are warranted to further investigate the safety and efficacy of this compound.

Randomized Controlled Trial Comparative Study
A prospective randomised controlled trial of the LMA Supreme vs cuffed tracheal tube as the airway device during percutaneous tracheostomy.
We studied the performance of the LMA Supreme against a cuffed tracheal tube, our standard method of airway control during percutaneous tracheostomy, in 50 consecutive patients from three general critical care units. The primary outcome measure was adequacy of ventilation calculated as the difference in arterial carbon dioxide tension before and after tracheostomy. ⋯ Eight patients out of 25 (32%) crossed over from the LMA Supreme group to the tracheal tube group before commencement of tracheostomy due to airway or ventilation problems, compared with none out of 25 in the tracheal tube group, p = 0.01, and tracheostomy was postponed in two patients in the LMA Supreme group due to poor oxygenation. There were more clinically important complications in the LMA Supreme group compared with the tracheal tube group.

Randomized Controlled Trial Comparative StudyModified Short-Axis Out-of-Plane Ultrasound Versus Conventional Long-Axis In-Plane Ultrasound to Guide Radial Artery Cannulation: A Randomized Controlled Trial.
Currently, short-axis out-of-plane (SA-OOP) and long-axis in-plane (LA-IP) ultrasound techniques are used to guide radial artery cannulation. In this study, we compared the success rate of a modified SA-OOP technique with that of traditional LA-IP. ⋯ The modified SA-OOP technique may improve the success rate of cannula insertion into the radial artery on the first attempt.

Randomized Controlled Trial
Midazolam and propofol used alone or sequentially for long-term sedation in critically ill, mechanically ventilated patients: a prospective, randomized study.
Midazolam and propofol used alone for long-term sedation are associated with adverse effects. Sequential use may reduce the adverse effects, and lead to faster recovery, earlier extubation and lower costs. This study evaluates the effects, safety, and cost of midazolam, propofol, and their sequential use for long-term sedation in critically ill mechanically ventilated patients. ⋯ Sequential use of midazolam and propofol was a safe and effective sedation protocol, with higher clinical effectiveness and better cost-benefit ratio than midazolam or propofol used alone, for long-term sedation of critically ill mechanically ventilated patients.

Randomized Controlled Trial Comparative StudyComparison of unilateral and bilateral spinal anesthesia with 2% hyperbaric prilocaine in day-case inguinal herniorrhaphy: a randomized controlled trial.
Hyperbaric 2% prilocaine produces a faster onset and shorter duration of spinal anesthesia than a plain solution. The anesthetic profile could be improved by restricting the block to the operative side. We compared unilateral versus conventional bilateral spinal anesthesia with hyperbaric 2% prilocaine in day-case patients undergoing unilateral inguinal herniorrhaphy. ⋯ In day-case inguinal herniorrhaphy, attempting unilateral spinal anesthesia with 50 mg hyperbaric 2% prilocaine produced faster time to voiding.
