Randomized Controlled Trial Comparative Study
Comparison between ultrasound-guided supraclavicular and infraclavicular approaches for subclavian venous catheterization in children--a randomized trial.
Ultrasound (US)-guided subclavian vein (SCV) catheterization via the supraclavicular (SC) or infraclavicular (IC) approaches can be useful in children. The purpose of this study was to compare the efficacy of these approaches. ⋯ During SCV catheterization under US guidance in paediatric patients, the SC approach yielded a shorter puncture time and decreased the incidence of guidewire misplacement when compared with the IC approach.

Review Meta Analysis
Regional anaesthesia to prevent chronic pain after surgery: a Cochrane systematic review and meta-analysis.
Epidural anesthesia may reduce post-thoracotomy chronic pain (OR 0.33) and paravertebral block reduce that following breast ca surgery (OR 0.37).

Comparative Study
Minimally invasive intraoperative estimation of left-ventricular end-systolic elastance with phenylephrine as loading intervention.
Left-ventricular end-systolic elastance (Ees) is an index of cardiac contractility, but the invasive nature of its assessment has limited perioperative application. We explored the feasibility of a minimally invasive method of Ees estimation for perioperative assessment of cardiac function and evaluated the suitability of phenylephrine as a loading intervention. ⋯ It is feasible to determine Ees combining continuous non-invasive arterial pressure measurements and left-ventricular volume determinations with TOE. However, administration of phenylephrine cannot substitute IVCC as a loading intervention, indicating that estimation of Ees in the intraoperative setting remains a challenge.

Cardiac output (CO) measurement with lithium dilution (COLD) has not been fully validated in sheep using precise ultrasonic flow probe technology (COUFP). Sheep generate important cardiovascular research models and the use of COLD has become more popular in experimental settings. ⋯ COLD is not precise when evaluated against COUFP in sheep based on the statistical criteria set, but the results are comparable with previously published animal studies.

Randomized Controlled Trial Comparative Study
Comparison of techniques for double-lumen endobronchial intubation: 90{degrees} or 180{degrees} rotation during advancement through the glottis.
Rotating through 180o assists intubation with a double lumen tube while reducing sore throat and vocal cord injuries.
