OBJECTIVE To characterize the beneficial effects of perioperative systemic lidocaine on length of hospital stay, gastrointestinal motility, and the inflammatory response after colorectal surgery. SUMMARY BACKGROUND DATA Surgery-induced stimulation of the inflammatory response plays a major role in the development of several postoperative disorders. Local(More)
PURPOSE OF REVIEW A significant proportion of critically ill patients with acute kidney injury require continuous renal replacement therapy (CRRT). This article summarizes current evidence on the diagnosis and treatment of acute kidney injury. Regional citrate anticoagulation (RCA) is an emerging but complex technique. A variety of solutions and systems are(More)
BACKGROUND The management of postoperative pain and recovery is still unsatisfactory in clinical practice. Opioids used for postoperative analgesia are frequently associated with adverse effects including nausea and constipation. These adverse effects prevent smooth postoperative recovery. On the other hand not all patients may be suited to, and take(More)
BACKGROUND Perioperative myocardial ischemia poses a vital threat to surgical patients. Means to protect postischemic myocardium are clinically not available. Lidocaine has been demonstrated to exert antiinflammatory pleiotropic effects. The authors set out to test if lidocaine protects ischemic myocardium from reperfusion injury. METHOD A mouse model of(More)
BACKGROUND N-methyl-D-aspartate (NMDA)-receptor activation contributes to postoperative hyperalgesia. Studies in volunteers have shown that intravenous local anaesthetics (LAs) prevent the development of hyperalgesic pain states. One potential explanation for this beneficial effect is the inhibition of NMDA receptor activation. Therefore, we studied the(More)
BACKGROUND AND OBJECTIVE Paracetamol has a well established pharmacological profile, but its postoperative efficacy is in question. This double-blind, placebo-controlled study was designed to compare the efficacy of intravenous paracetamol with other intravenous non-opioids as part of a multimodal concept for perioperative pain therapy. METHODS Patients(More)
The oculocardiac reflex (OCR) is induced by mechanical stimulation and therefore is frequently encountered during strabismus surgery. This study was designed to determine how various anaesthetic regimes modulate the haemodynamic effects of the OCR during paediatric strabismus surgery. Thirty-nine patients (4-14 years, ASA I) were randomized to one of four(More)
PURPOSE OF REVIEW The aim of this review is to describe the pharmacology, toxicology and chemistry of the new group of local anesthetics of phenylcarbamic acid type. RECENT FINDINGS Basic esters of alkoxy-substituted phenylcarbamic acid have shown high local anesthetic potency, while maintaining a relatively safe toxicity profile. Their potency uniquely(More)
BACKGROUND Nonselective nitric oxide synthase (NOS) inhibition has detrimental effects in sepsis because of inhibition of the physiologically important endothelial NOS (eNOS). The authors hypothesized that selective inducible NOS (iNOS) inhibition would maintain eNOS vasodilation but prevent acetylcholine- and bradykinin-mediated vasoconstriction caused by(More)
BACKGROUND Clinical studies suggest that intraoperative administration of the clinical remifentanil formulation Ultiva (GlaxoWellcome GmbH & Co, Bad Oldesloe, Germany) increases postoperative pain and postoperative analgesic requirements, but mechanisms remain unclear. N-methyl-D-aspartate (NMDA) receptors are thought to play a major role in development of(More)
