Randomized Controlled Trial Comparative Study[Internal jugular venous cannulation: what is the best approach?].
The aim of this study was to compare two approaches used for internal jugular venous cannulation: the anterior way, described by English et al. and the posterior way, described by Jernigan et al. The primary endpoint was the rate of success. The secondary endpoints were the related adverse events and the difficulty factors. ⋯ This study shows that the posterior approach in internal jugular venous cannulation is more efficient than and as safe as the anterior approach.

Review[The perioperative period in cancer surgery: a critical moment! Is there a role for regional anesthesia in preventing cancer recurrence?].
Surgical treatment of cancer is usually necessary but it can paradoxically aggravate the patient outcome by increasing the risk of recurrence. Many perioperative factors have been shown to contribute to the dissemination of the tumor: surgery itself, stress, inflammation, pain, anaesthetic drugs, blood transfusion, etc. ⋯ Experimental, preclinical and retrospective studies have suggested that a regional anesthesia associated or not with a general anesthesia for carcinologic surgery might reduce the risk of cancer recurrence. This text reviews the factors promoting the recurrence of tumors after carcinologic surgery and the potential possibilities of protection associated with the type of anaesthesia chosen.

The brain and the lungs interact early and rapidly when hit by a disease process. Often well tolerated by the healthy brain, an impaired respiratory function may deteriorate further a "sick" brain. Hypoxemia is a prognostic factor in the brain-injured patients. ⋯ The management of brain-injured patients has to be directed toward the protection of both the brain and lung. Neuronal preservation is crucial, because of the lack of regenerative potential in the brain, unlike the lung. A compromise must be obtained between the cerebral and pulmonary treatments although they may conflict in some situations.

Review[Interest of EEG recording during direct electrical stimulation for brain mapping function in surgery].
Brain tumor surgery is at risk when lesions are located in eloquent areas. The interindividual anatomo-functional variability of the central nervous system implies that brain surgery within eloquent regions may induce neurological sequelae. Brain mapping using intraoperative direct electrical stimulation in awake patients has been for long validated as the standard for functional brain mapping. ⋯ To improve the sensitivity and specificity of this technique, we used an electrocorticographic recording system allowing a real time visualization of the local. We provide here evidence that direct cortical stimulation combined with electrocorticographic recording could be useful to detect remote after discharge and to adjust stimulation parameters. In addition this technique offers new perspective to better assess connectivity of cerebral networks.

Randomized Controlled Trial[Preloading with HES 130/0.4 versus normal saline solution to prevent hypotension during spinal anaesthesia for elective caesarean section].
To evaluate the efficacy of HES 130/0.4 preload compared to normal saline solution for prevention of hypotension during spinal anaesthesia for elective caesarean section. ⋯ HES 130/0.4 preload reduced the incidence of hypotension, the duration of longest hypotension, and the need for ephedrine during spinal anaesthesia for elective caesarean section. However, the efficacy of HES 130/0.4 alone in prevention of maternal hypotension during spinal anaesthesia for caesarean section is still insufficient.
