The purpose of our research is to contribute to a better understanding of the residual brain function of patients who survive an acute brain damage but remain in a coma, vegetative state, minimally conscious state or locked-in syndrome. The diagnosis, prognosis, therapy and medical management of these patients remain difficult. These studies are also of interest scientifically, as they help to elucidate the neural correlates of human consciousness. We here review our studies on bedside behavioral evaluation scales, electrophysiology and functional neuroimaging in these disorders of consciousness and conclude by discussing methodological and ethical issues and current concepts of the standards for care and quality of life in these challenging conditions.

Improvement in functional neuroimaging allows researchers to disentangle the brain mechanisms involved in the pain modulation encountered during hypnosis. It has been shown that the anterior cingulate and prefrontal cortices are important in the modulation of incoming sensory and noxious input. Moreover, clinical studies in certain types of surgery (eg thyroidectomy, mastectomy and plastic surgery) have demonstrated that hypnosis may avoid general anesthesia. [less ▲]

Over the last fifteen years, child's pain has become one of our major concerns. In spite of this evolution, it remains one of the most frequent complications after ambulatory surgery. It is thus essential to implement all the resources we have at our disposal in order to optimize pain management. This can be obtained by basing our strategy on the concept of multimode analgesia. It is consequently essential that each team can achieve its own quality program; the corollary will be the development of clear recommendations for the parents with a systematic analgesics regulation at home and the possibility to resort to the family doctor or to the ambulatory centre in the event of persistence of pain.

Resveratrol is a polyphenolic antioxidant present in beverage and food known for its multiple protective effects. We report the inhibitory effects of resveratrol on equine myeloperoxidase (MPO), a hemic peroxidase present in the granules of the neutrophils involved in the inflammatory response. Resveratrol inhibited the production of reactive oxygen species (ROS) by stimulated equine neutrophils by acting as a direct scavenger of the ROS released by the cells but did not modify the degranulation of the stimulated neutrophils as the amounts of released MPO were unchanged. Resveratrol strongly inhibited the chlorination, oxidation, and nitration activities of MPO in a dose-dependent manner. By an original technique of specific immunological extraction followed by enzymatic detection (SIEFED), we demonstrated that resveratrol inhibited the peroxidasic activity of the MPO measured by a direct interaction such as the fixation of resveratrol on the enzyme. The observation of a decrease of the accumulation of compound II suggested that resveratrol acts as an electron donor for MPO reduction. [less ▲]

There is an increasing body of evidence that volatile anaesthetics protect myocardium against ischaemic insult by a mechanism termed 'anaesthetic preconditioning'. Anaesthetic preconditioning and ischaemic preconditioning share several common mechanisms of action. Since ischaemic preconditioning has been demonstrated in organs other than the heart, anaesthetic preconditioning might also apply in these organs and have significant clinical applications in surgical procedures carrying a high risk of ischaemia-reperfusion injury. After a brief review on myocardial preconditioning, experimental and clinical data on preconditioning in non-cardiac tissues will be presented. Potential benefits of anaesthetic preconditioning during non-cardiac surgery will be addressed. [less ▲]

Although often clinically silent, pancreatic cellular injury (PCI) is relatively frequent after cardiac surgery with cardiopulmonary bypass; and its etiology and time course are largely unknown. We defined PCI as the simultaneous presence of abnormal values of pancreatic isoamylase and immunoreactive trypsin (IRT). The frequency and time evolution of PCI were assessed in this condition using assays for specific exocrine pancreatic enzymes. Correlations with inflammatory markers were searched for preoperative risk factors. One hundred ninety-three patients submitted to cardiac surgery were enrolled prospectively. Blood IRT, amylase, pancreatic isoamylase, lipase, and markers of inflammation (alpha1-protease inhibitor, alpha2-macroglobulin, myeloperoxidase) were measured preoperatively and postoperatively until day 8. The postoperative increase in plasma levels of pancreatic enzymes and urinary IRT was biphasic in all patients: early after surgery and later (from day 4 to 8 after surgery). One hundred thirty-three patients (69%) experienced PCI, with mean IRT, isoamylase, and alpha1-protease inhibitor values higher for each sample than that in patients without PCI. By multiple regression analysis, we found preoperative values of plasma IRT >or=40 ng/mL, amylase >or=42 IU/mL, and pancreatic isoamylase >or=20 IU/L associated with a higher incidence of postsurgery PCI (P < 0.005). In the PCI patients, a significant correlation was found between the 4 pancreatic enzymes and urinary IRT, total calcium, myeloperoxidase, alpha1-protease inhibitor, and alpha2-macroglobulin. These data support a high prevalence of postoperative PCI after cardiac surgery with cardiopulmonary bypass, typically biphasic and clinically silent, especially when pancreatic enzymes were elevated preoperatively.

The one day clinic possesses its own structure and organisation; patient management is also specific. Preoperative visit and assessment are programmed at least 48 hours before anesthesia. Preoperative examinations and choice of anesthetic technique (sedation associated with local anesthesia or not, general anesthesia, locoregional anesthesia, or hypnosedation) are discussed and determined depending upon medical history, clinical examination, and type of procedure. General recommandations, instructions about fasting, interruption of some therapies, and introduction of new medication(s) are explained orally and also provided in a written document. New anesthetics and analgesics allow quick awakening and recovery of vital functions, and subsequently rapid hospital discharge. Prevention and aggressive treatment of postoperative nausea and vomiting are also a major concern in our anesthesic management of ambulatory patient. [less ▲]

BACKGROUND: Intravenous infusion of lidocaine decreases postoperative pain and speeds the return of bowel function. The authors therefore tested the hypothesis that perioperative lidocaine infusion facilitates acute rehabilitation protocol in patients undergoing laparoscopic colectomy. METHODS: Forty patients scheduled to undergo laparoscopic colectomy were randomly allocated to receive intravenous lidocaine (bolus injection of 1.5 mg/kg lidocaine at induction of anesthesia, then a continuous infusion of 2 mg.kg.h intraoperatively and 1.33 mg.kg.h for 24 h postoperatively) or an equal volume of saline. All patients received similar intensive postoperative rehabilitation. Postoperative pain scores, opioid consumption, and fatigue scores were measured. Times to first flatus, defecation, and hospital discharge were recorded. Postoperative endocrine (cortisol and catecholamines) and metabolic (leukocytes, C-reactive protein, and glucose) responses were measured for 48 h. Data (presented as median [25-75% interquartile range], lidocaine vs. saline groups) were analyzed using Mann-Whitney tests. P<0.05 was considered statistically significant. RESULTS: Patient demographics were similar in the two groups. Times to first flatus (17 [11-24] vs. 28 [25-33] h; P<0.001), defecation (28 [24-37] vs. 51 [41-70] h; P=0.001), and hospital discharge (2 [2-3] vs. 3 [3-4] days; P=0.001) were significantly shorter in patients who received lidocaine. Lidocaine significantly reduced opioid consumption (8 [5-18] vs. 22 [14-36] mg; P=0.005) and postoperative pain and fatigue scores. In contrast, endocrine and metabolic responses were similar in the two groups. CONCLUSIONS: Intravenous lidocaine improves postoperative analgesia, fatigue, and bowel function after laparoscopic colectomy. These benefits are associated with a significant reduction in hospital stay. [less ▲]

In the last years, there has been an increasing interest of using cyclooxygenase-2 (COX-2) inhibitors to treat the inflammatory pain and chronic inflammatory diseases such as osteoarthritis and rheumatoid arthritis. The beneficial effects were to avoid the secondary adverse effects such as bleeding and gastric irritation, generally observed with aspirin and conventional NSAIDs. COX-1 is constitutively expressed in most tissues and involved in the regulation of normal homeostatic functions, while COX-2 is not detected in most tissues but induced by inflammatory stimuli. These outcomes motivated the commercial development of selective COX-2 inhibitors. Recent data suggested that the COX-2 enzyme can be expressed within atherosclerotic lesions and could play a crucial role in various types of cancers, by the way of its activity on the ROS production, gene transcription and prostaglandin (PGE2) production. Consequently, the COX-2 enzyme has become a real target for the study of various classes of compounds and specially the possible additional properties of COX-2 inhibitors. We and other groups have already investigated the pro or antioxidant profile of conventional NSAIDs and some COX-2 inhibitors. With the recent withdrawal of two compounds of the coxib’s family (rofecoxib and celecoxib), for adverse cardiovascular events, concerns regarding the safety of all COX-2 inhibitors have been raised. To answer to these concerns, different approaches were developed by studying on in vitro models, the potential inhibiting-or-stimulating activities on oxidative phenomena of new drugs with already recognized therapeutic effects. Preliminary data obtained with COX-2 inhibitors showed a moderate inhibiting effect on the intracellular oxidant processes and others a stimulating activity. New hypotheses for the treatment of inflammation are now suggested for compounds like nimesulide and its analogous, which are selective towards COX-2 with little activity on COX-1. Here, we reported the in vitro effects of some Cox-2 inhibitors, in comparison with traditional drugs (ibuprofen, diclofenac and aceclofenac) by using two cellular models: a human lung type II alveolar cell line (A549) and a human promonocyte cell line (THP-1). The direct interactions between the drugs and ROS were also investigated in cell-free systems. [less ▲]
