The objective was to present a proof of concept for a simple and consistently successful ultrasonograpy (US)-guided technique to block the internal branch of the superior laryngeal nerve (iSLN). ⋯ A simpler and consistently reproducible US-guided iSLN block is feasible using the thyrohyoid membrane as target plane for local anesthetic injection. Clinical trials are needed to determine its effectiveness and safety, needle entry point, trajectory, and local anesthetic volume.

Randomized Controlled Trial Comparative Study
The effect of magnesium sulphate on intubating condition for rapid-sequence intubation: a randomized controlled trial.
We compared magnesium sulphate with control, ketamine, rocuronium prime, and large-dose rocuronium (0.9 mg/kg) with regard to intubation conditions during rapid-sequence induction. ⋯ Magnesium sulphate pretreatment was most likely to provide excellent intubating condition for rapid-sequence intubation compared with the control, ketamine pretreatment, rocuronium prime, and large-dose rocuronium. However, magnesium sulphate administration is associated with a burning or heat sensation.

Randomized Controlled Trial
Clinical application of a novel developed pressure bladder indicator in lumbar epidural puncture.
A novel pressure bladder indicator was developed, and this study aimed to evaluate the clinical application of the pressure bladder indicator by measuring the epidural space pressure and bladder working pressure on patients undergoing lumbar epidural puncture. ⋯ The novel developed pressure bladder indicator was a reliable and useful technique to conduct successful lumbar epidural puncture.

Randomized Controlled Trial Comparative Study
A simple diagnostic test to confirm correct intravascular placement of peripheral catheters in order to avoid extravasation.
Intravenous catheters are ubiquitous among modern medical management of patients, yet misplaced or tissued cannulas can result in serious iatrogenic injury due to infiltration or extravasation of injectate. Prevention is difficult, and currently few reliable tests exist to confirm intravascular placement of catheters in awake spontaneously breathing patients. ⋯ Intravenous injection of dilute sodium bicarbonate with exhaled carbon dioxide monitoring reliably confirms correct intravascular placement of a catheter. A transient increase of exhaled carbon dioxide by 10% or more is an objective and reliable confirmation of intravascular location of the catheter. We recommend using 20 mL of 4.2% sodium bicarbonate to minimize the mEq dose of sodium bicarbonate required.

To determine the demographic characteristics of patients undergoing primary total knee arthroplasty during the years 1989, 1999, and 2009 at our institution and determine whether their characteristics mirror the changing US demographic characteristics. ⋯ The number of obese patients with comorbidities who present for total knee arthroplasty at our institution has increased over the past 20 years. Despite this fact, a reduction was detected in postoperative complications.
