This article reviews the recent evidence on perioperative neuroprotection in patients undergoing brain surgery and in patients with acute stroke. ⋯ Recent evidence provides insufficient evidence of neuroprotective strategies to guide clinical management, and more randomized clinical trials are needed to optimize patient care.

Ultrasound guidance is frequently utilized for needle placement and observation of local anesthetic spread when performing peripheral nerve blocks. Although there is evidence that ultrasound technology can reduce complications, there are limitations to 2-dimensional (2-D) ultrasound. Three-dimensional (3-D) and especially real-time 3-D (4-D) ultrasound may allow for optimized and well tolerated needle positioning and enhanced observation of local anesthetic spread around the target structure. This article reviewed the current literature regarding the use of 3-D and 4-D ultrasound technology in a regional anesthesia setting. ⋯ At present, there are limited data regarding the use of 3-D ultrasound and a complete lack of randomized controlled clinical trials evaluating the potential benefits of real-time 3-D (4-D) ultrasound. This may be in part due to technical limitations associated with these techniques.

ReviewTraumatic brain injury: physiological targets for clinical practice in the prehospital setting and on the Neuro-ICU.
Over many years, understanding of the pathophysiology in traumatic brain injury (TBI) has resulted in the development of core physiological targets and therapies to preserve cerebral oxygenation, and in doing so prevent secondary insult. The present review revisits the evidence for these targets and therapies. ⋯ Maintaining physiological targets in several areas remains part of protocol led care in the acute phase of TBI management. As evidence accumulates however, the target values and therefore therapies may be set to change.

Monitoring and therapy of patients in neurocritical care are areas of intensive research and the current evidence needs further confirmation. ⋯ Although strong evidence is lacking, multimodal monitoring is of great value in neurocritical care patients and may help to provide patients with the optimal therapy based on the individual pathophysiological changes.
