BACKGROUND: Mechanisms of anesthesia-induced loss of consciousness remain poorly understood. Resting-state functional magnetic resonance imaging allows investigating whole-brain connectivity changes during pharmacological modulation of the level of consciousness. METHODS: Low-frequency spontaneous blood oxygen level-dependent fluctuations were measured in 19 healthy volunteers during wakefulness, mild sedation, deep sedation with clinical unconsciousness, and subsequent recovery of consciousness. RESULTS: Propofol-induced decrease in consciousness linearly correlates with decreased corticocortical and thalamocortical connectivity in frontoparietal networks (i.e., default- and executive-control networks). Furthermore, during propofol-induced unconsciousness, a negative correlation was identified between thalamic and cortical activity in these networks. Finally, negative correlations between default network and lateral frontoparietal cortices activity, present during wakefulness, decreased proportionally to propofol-induced loss of consciousness. In contrast, connectivity was globally preserved in low-level sensory cortices, (i.e., in auditory and visual networks across sedation stages). This was paired with preserved thalamocortical connectivity in these networks. Rather, waning of consciousness was associated with a loss of cross-modal interactions between visual and auditory networks. CONCLUSIONS: Our results shed light on the functional significance of spontaneous brain activity fluctuations observed in functional magnetic resonance imaging. They suggest that propofol-induced unconsciousness could be linked to a breakdown of cerebral temporal architecture that modifies both within- and between-network connectivity and thus prevents communication between low-level sensory and higher-order frontoparietal cortices, thought to be necessary for perception of external stimuli. They emphasize the importance of thalamocortical connectivity in higher-order cognitive brain networks in the genesis of conscious perception. [less ▲]

Aim: Donation after cardiac death (DCD) has been proposed to partly overcome the organ donor shortage. In liver transplantation, the additional warm ischemia linked to DCD procurement may promote higher rate of primary non-function and ischemic type biliary lesions. In this study we reviewed the results of DCD liver transplantation at the University of Liège. Patients and Methods: From 2003 to 2007, 13 controlled DCD liver transplantations were consecutively performed. The records of all donors and recipients were retrospectively reviewed, particularly evaluating the outcome and the occurrence of biliary complications. Mean follow-up was 25 months. Results: Mean donor age was 51 years and their mean intensive care stay was 5.4 days. Mean time between ventilation arrest and cardiac arrest was 9.3 min. Mean time between cardiac arrest and arterial flush was 7.7 min. No touch period was 2 to 5 min. Mean graft cold ischemia was 295 min and mean suture warm ischemia was 38 min. Postoperatively there was no primary non-function. Mean peak transaminase was 2,546 UI/ml. Patient and graft survival was 100% at one year. Two patients (15%) developed graft main bile duct stenosis and underwent endoscopic management. No patient developed symptomatic intrahepatic bile duct strictures or needed retransplantation in the follow-up. Conclusions: The experience of the transplantation department of the University of Liege confirms that controlled DCD donors may be a valuable source of transplantable liver grafts, in case of short procurement warm ischemia and short transplant cold ischemia.

Morbid obesity results in a restrictive pulmonary syndrome including decreased functional residual capacity. General anaesthesia further decreases functional residual capacity, and consequently alters gas exchanges more profoundly in morbidly obese patients than in nonobese patients. Moreover, these changes persist longer during the postoperative period, rendering obese subjects vulnerable to postoperative respiratory complications. In this review, we present postoperative measures improving respiratory function of these patients. Whether these measures affect outcome remains however unknown. Patients suffering from obstructive sleep apnoea syndrome deserve special considerations that are briefly described. Finally, the algorithm of the postoperative respiratory management of morbid obese patients used in our institution is provided. [less ▲]

Short- and long-term results of liver transplantation in morbidly obese patients may be impaired compared with the general transplant population. As a consequence, severe obesity has been considered to be a relative contraindication to liver transplantation in many centers. Surgically, liver transplantation in severe obesity may be challenging. Moreover, obesity may lead to an increased rate of early and late medical complications. Herein we have reported successful liver transplantation in a super-obese patient (body mass index, 55.1 kg/m(2)) who had developed terminal acute-on-chronic liver disease. In the first 6 months of follow-up, the patient underwent a severe diet that led to a significant weight loss reduction to a body mass index of 39 kg/m(2). This report of successful liver transplantation in a super-obese patient suggests that severe obesity should not be considered to be an absolute contraindication to liver transplantation. [less ▲]

Most of the textbooks of anesthesia do not devote any chapter to anesthesia for abdominal surgery. Whereas the choice of anesthetics has minimal impact on postoperative outcome of the patient scheduled for these procedures global perioperative anesthetic management however affects postoperative recovery, convalescence, or even morbidity. This presentation highlights practical measures susceptible of reducing postoperative complications and of shortening patient convalescence. [less ▲]
