Intraoperative blood glucose management: impact of a real-time decision support system on adherence to institutional protocol.
Poor perioperative glycemic management can lead to negative surgical outcome. Improved compliance to glucose control protocol could lead to better glucose management. An Anesthesia Information Management System based decision support system-Smart Anesthesia Manager™ (SAM) was used to generate real-time reminders to the anesthesia providers to closely adhere to our institutional glucose management protocol. ⋯ Compliance to hourly glucose measurement and correct insulin doses increased significantly during the intervention period when compared with the baseline (from 52.6 to 71.2 % and from 13.5 to 24.4 %, respectively). In spite of improved compliance to institutional protocol, the mean glucose levels and other glycemic management parameters did not show significant improvement with SAM reminders. Real-time electronic reminders improved intraoperative compliance to institutional glucose management protocol though glycemic parameters did not improve even when there was greater compliance to the protocol.

Normal pressure hydrocephalus frequently develops after subarachnoid hemorrhage. It can often be difficult, however, to predict shunt dependency. The purpose of this study was to identify predictors of shunt-dependent normal pressure hydrocephalus (SDNPH) after aneurysmal subarachnoid hemorrhage (aSAH). ⋯ SDNPH after aSAH in our study showed no correlations with three of the parameters previously identified as risk factors for shunt-dependent hydrocephalus, namely, the amount of SAH, the presence of IVH, or acute hydrocephalus. Instead, a longer duration of CSF drainage correlated with SDNPH as an independent factor. These data suggest that a longer duration of CSF drainage may be one of the risk factors for SDNPH after aSAH.

Pseudoaneurysm in the Internal Maxillary Artery Occurring After Endoscopic Sinus Surgery.
Pseudoaneurysm is defined as blood leaking out of a vessel that does not have true 3 arterial walls like a true aneurysm, and is susceptible to rupture. Only 4 patients of pseudoaneurysm after endoscopic sinus surgery have been reported so far in English literature. Recently, the authors encountered a pseudoaneurysm in the internal maxillary artery after endoscopic sinus surgery, which was immediately and successfully managed with endovascular embolization. There was no bleeding or complications 6 months after the embolization.

The Surgical Workforce and Surgical Provider Productivity in Sierra Leone: A Countrywide Inventory.
Limited data exist on surgical providers and their scope of practice in low-income countries (LICs). The aim of this study was to assess the distribution and productivity of all surgical providers in an LIC, and to evaluate correlations between the surgical workforce availability, productivity, rates, and volume of surgery at the district and hospital levels. ⋯ Less than half of all of the surgery in Sierra Leone is performed by specialists. Surgical providers were significantly more productive in healthcare facilities with higher volumes of surgery. If all surgical providers were as productive as specialists in the private non-profit sector (5.1 procedures/week), the national volume of surgery would increase by 85 %.

Combined 2D and 3D tracking of surgical instruments for minimally invasive and robotic-assisted surgery.
Computer-assisted interventions for enhanced minimally invasive surgery (MIS) require tracking of the surgical instruments. Instrument tracking is a challenging problem in both conventional and robotic-assisted MIS, but vision-based approaches are a promising solution with minimal hardware integration requirements. However, vision-based methods suffer from drift, and in the case of occlusions, shadows and fast motion, they can be subject to complete tracking failure. ⋯ We demonstrate from our extended sequences that our method provides drift-free robust and accurate tracking. Our occlusion-based sequences additionally demonstrate that our method can recover from occlusion-based failure. In both cases, we show an improvement over using 3D tracking alone suggesting that combining 2D and 3D tracking is a promising solution to challenges in surgical instrument tracking.
