BACKGROUND Blockade of parietal nociceptive afferents by the use of continuous wound infiltration with local anesthetics may be beneficial in a multimodal approach to postoperative pain management after major surgery. The role of continuous preperitoneal infusion of ropivacaine for pain relief and postoperative recovery after open colorectal resections was(More)
BACKGROUND AND STUDY AIMS Very recently, robotic single site cholecystectomy (RSSC) has been reported feasible and safe for selected cases. While an intra-operative cholangiography can be performed, data is scarce with respect to its use. Indocyanin green (ICG) has been shown to be a viable option to visualize biliary anatomy. Since the introduction of a(More)
Epidermal growth factor receptor (EGFR) binds transforming growth factor alpha (TGF-alpha) which is mitogenic for hepatocytes. Diverse lines of evidence suggest that activation of the TGF-alpha /EGFR pathway contributes to hepatocellular carcinoma (HCC) formation. Herein, we developed an experimental model of cirrhosis giving rise to HCC and tested the(More)
SUMMARY Several indirect laryngoscopes have recently been developed, but relatively few have been formally compared. In this study we evaluated the efficacy and the usability of the Macintosh, the Glidescope, the McGrath and the Airtraq laryngoscopes. Sixty anaesthesia providers (20 staff, 20 residents, and 20 nurses) were enrolled into this study. The(More)
OBJECTIVE The aim of this study was to compare open and laparoscopic sigmoid resection for diverticulitis with the patient and the nursing staff blinded to the surgical approach. METHODS A total of 113 patients scheduled for an elective sigmoidectomy were randomized to receive either a conventional open (54 patients) or a laparoscopic (59 patients)(More)
BACKGROUND AND OBJECTIVES Clonidine is added to intrathecal local anesthetics to improve intraoperative analgesia and to increase the duration of sensory and motor block. The aim of this systematic review is to quantify beneficial and harmful effects of clonidine when used as an adjuvant to intrathecal local anesthetics for surgery. METHODS We included(More)
Liver fibrosis is produced by myofibroblasts of different origins. In culture models, rat myofibroblasts derived from hepatic stellate cells (HSCs) and from periductal portal mesenchymal cells, show distinct proliferative and immunophenotypic evolutive profiles, in particular regarding desmin microfilament (overexpressed vs shut-down, respectively). Here,(More)
The extent of sensory block during spinal anaesthesia is unpredictable and is influenced by many factors, mainly patient position, site of injection, baricity and the dose of drug injected. Among other factors, cerebrospinal fluid (CSF) density has been advocated to affect subarachnoid distribution of local anaesthetics. In this study, we have investigated(More)
BACKGROUND AND OBJECTIVES Intrathecal morphine is a widely used method for postoperative pain relief after major abdominal surgery. The aim of this randomized, double-blinded study was to compare intrathecal morphine and intravenous PCA morphine for postoperative analgesia and recovery course after major colorectal surgery in elderly patients. METHODS(More)
UNLABELLED To determine the effects of clonidine with ropivacaine during epidural labor analgesia, we studied 66 nulliparous women in early active labor. Women were randomized to receive ropivacaine 0.1% 8 mL plus 75 microg of clonidine (Group 1), ropivacaine 0.2% 8 mL plus 0.5 mL of NaCl 0.9% (Group 2), or ropivacaine 0.2% 8 mL plus 75 microg of clonidine(More)
