This is a review on the techniques for assessing liver function in critically ill patients. ⋯ Since no ideal tool is currently available, dynamic tests such as indocyanine green plasma disappearance rate and monoethylglycinxylidide test may be recommended for assessing liver function in critically ill patients. The indocyanine green plasma disappearance rate has the advantage, however, of being measurable noninvasively at the bedside and providing results within a few minutes.

ReviewNeuroprotection in traumatic brain injury: a complex struggle against the biology of nature.
Translating the efficacy of neuroprotective agents in experimental traumatic brain injury to clinical benefit has proven an extremely complex and, to date, unsuccessful undertaking. The focus of this review is on neuroprotective agents that have recently been evaluated in clinical trials and are currently under clinical evaluation, as well as on those that appear promising and are likely to undergo clinical evaluation in the near future. ⋯ Traumatic brain injury is a complex disease, and development of clinically effective neuroprotective agents is a difficult task. Experimental traumatic brain injury has provided numerous promising compounds, but to date these have not been translated into successful clinical trials. Continued research efforts are required to identify and test new neuroprotective agents, to develop a better understanding of the sequential activity of pathophysiologic mechanisms, and to improve the design and analysis of clinical trials, thereby optimizing chances for showing benefit in future clinical trials.

ReviewCurrent status of cerebral protection with mild-to-moderate hypothermia after traumatic brain injury.
The aim of this article is to review the current status of protective effects of mild-to-moderate hypothermia on traumatic brain injury. ⋯ Mild-to-moderate hypothermia plays a significant role in cerebral protection after traumatic brain injury.

Controversy still exists about the management of spontaneous intracerebral haemorrhage. This review summarizes our current knowledge on indications and benefits of surgery for intracerebral haemorrhage. It further describes the detailed meta-analysis of the surgical results in lobar (superficial) supratentorial intracerebral haemorrhage, summarizes the limited information on the surgical treatment of cerebellar intracerebral haemorrhage, and identifies three ongoing trials. ⋯ Clinicians are encouraged to discover if the suspected beneficial role of surgery truly exists by randomizing patients with intracerebral haemorrhage in the ongoing prospective randomized controlled trials in the following circumstances: lobar intracerebral haemorrhage (clot reaches to within 1 cm of the cortical surface), STICH II; intraventricular haemorrhage (clot maximum size of 30 ml), CLEAR IVH; deep intracerebral haemorrhage and minimal invasive surgery, MISTIE.

This review provides a background in mechanical ventilation and sleep. ⋯ Minimizing the sleep alterations in mechanically ventilated patients could be obtained by setting the ventilator in such a way to avoid hyperventilation during the sleep stage. The impact of sleep derangements in patient outcomes is, however, unknown.
