Randomized Controlled Trial Comparative Study
Intrathecal hyperbaric 2% prilocaine versus 0.4% plain ropivacaine for same-day arthroscopic knee surgery: a prospective randomized double-blind controlled study.
Short-duration spinal anesthesia is a good option for ambulatory knee surgery. Hyperbaric 2% prilocaine has short onset and rapid recovery times and, therefore, may be well suited in this setting. The aim of this study was to compare the times to reach motor block, motor block resolution, and discharge from the postanesthesia care unit (PACU) between hyperbaric 2% prilocaine and 0.4% plain ropivacaine. ⋯ The recovery of motor block was faster after intrathecal administration of hyperbaric 2% prilocaine compared with 0.4% plain ropivacaine; however, discharge time was similar between the two groups. Both drugs showed a similar risk profile.

Randomized Controlled Trial Comparative Study
Comparison of the endotracheal tube cuff pressure between a tapered- versus a cylindrical-shaped cuff after changing from the supine to the lateral flank position.
Positional change can displace an endotracheal tube (ETT) and change the ETT cuff pressure in a tracheally intubated patient. Endotracheal tubes with different cuff shapes may lead to different cuff pressures after positional change. We hypothesized that the intracuff pressure in the TaperGuard™ ETT with a tapered-shaped cuff would be higher than that in the conventional ETT with a cylindrical-shaped cuff after a change from the supine to the lateral flank position. ⋯ After the change from the supine to the lateral flank position, the ETT cuff pressure was significantly higher in the TaperGuard ETT than in the conventional ETT, although the extent of cephalad displacement of the ETT was comparable between the two groups. This trial was registered at Clinicaltrials.gov: NCT02165319.

Case Reports
Inferior vena cava filter migration during the prone position for spinal surgery: a case report.
Inferior vena cava (IVC) filters have been used as an alternative therapy for patients with a contraindication to anticoagulation. We present a case of an IVC filter migration to the right ventricle occurring while a trauma patient was undergoing spinal surgery in the prone position. The patient provided written consent to describe this case. ⋯ The prone position during surgery can induce anatomic and hemodynamic changes in the IVC. This may contribute to the migration of IVC filters--especially flexible retrievable filters. Careful handling and positioning of patients with IVC filters is recommended to avoid a sudden increase in IVC pressure that may predispose to IVC filter migration.

The real cost of care: focus on value for money, rather than price-tags.
