Randomized Controlled Trial Comparative Study
The effect of benzydamine hydrochloride on preventing postoperative sore throat after total thyroidectomy: a randomized-controlled trial.
We compared the effects of benzydamine hydrochloride (BH), 10% lidocaine, and normal saline spray on preventing postoperative sore throat (POST) in patients who underwent total thyroidectomy (TT). ⋯ Application of BH spray on the ETT cuff reduced the incidence and severity of POST at 12 hr after TT. We suggest this method to be a non-invasive and effective management option for POST without serious side effects.

Randomized Controlled Trial Comparative Study Observational Study
Accuracy of blood glucose measurements using the NOVA StatStrip® glucometer during cardiac surgery: a prospective observational study.
The Nova StatStrip® Glucose Hospital Meter System (Nova Biomedical, Waltham, MA, USA) is United States Food and Drug Administration approved for point-of-care use in critically ill patients, but its use during cardiac surgery has not been evaluated. In this study, we compare glucose values obtained during cardiac surgery by StatStrip® with values obtained by a blood gas analyzer. ⋯ Arterial blood glucose measurement by StatStrip was accurate before CPB, but lacked accuracy during and after CPB. Glucose values should be interpreted with caution when intensive glucose control protocols are being used during cardiac surgery.

Observational Study
Anatomical evaluation of the extent of spread in the erector spinae plane block: a cadaveric study.
The erector spinae plane (ESP) block is an interfascial analgesic technique first described as an alternative for pain control at the thoracic level. The objective of this observational study was to determine the anatomical spread of dye following a T7 ESP block in a cadaveric model. ⋯ The results suggest that the ESP block reaches a wide range of the posterior rami of spinal nerves without diffusion into the paravertebral space or involvement of the anterior rami.

The local anesthetic injectate spread with fascial plane blocks and corresponding clinical outcomes may vary depending on the site of injection. We developed and evaluated a supra-iliac approach to the anterior quadratus lumborum (QL) block and hypothesized that this single injection might successfully block the lumbar and sacral plexus in cadavers and provide analgesia for patients undergoing hip surgery. ⋯ This cadaveric study and case series show that a supra-iliac approach to the anterior QL block involved T10--L3 nerve territories and dermatomal coverage with no sacral plexus spread. This technique may have clinical utility for analgesia in hip surgery.
