BACKGROUND There have been recent changes with regard to tools and concepts for respiratory management of children undergoing general anesthesia. OBJECTIVES To determine the practice of pediatric anesthetists concerning: preoxygenation, breathing systems, ventilation modes, anesthetic agent and airway device, strategies for a general anaesthetic of less(More)
We measured the time it takes to reach the desired inspired anesthetic concentration using the Primus (Drägerwerk, AG, Lübeck, Germany) and the Avance (GE Datex-Ohmeda, Munich, Germany) anesthesia machines with toddler and newborn ventilation settings. The time to reach 95% of inspired target sevoflurane concentration was measured during wash-in from 0 to 6(More)
We investigated the role of the glutamatergic and endogenous opioidergic systems in the paradoxical pain evoked by the simultaneous application of innocuous warm and cold stimuli to the skin with a "thermal grill". Two parallel randomized, double-blind, cross-over studies, including two groups of 12 healthy volunteers, were carried out to compare the(More)
The incidents related to the medical devices are common during anesthesia and in intensive care unit. These incidents are rarely the cause of complications because monitoring detects them early; alternative scenarios allow bearing these problems. Although the incidence of these complications has much declined, these incidents are serious adverse events and(More)
BACKGROUND Preoperative flushing of an anesthesia workstation is an alternative for preparation of the anesthesia workstation before use in malignant hyperthermia-susceptible patients (MHS). We studied in vitro, using a test lung, the washout profile of sevoflurane in 7 recent workstations during adult and, for the first time, pediatric ventilation(More)
The simultaneous application of innocuous cutaneous warm and cold stimuli with a thermal grill can induce both paradoxical pain and paradoxical warmth (heat). The goal of this study was to investigate further the relationships between these paradoxical sensations. Stimuli were applied to the palms of the right hands of 21 volunteers with a thermode(More)
The technology of anesthesia ventilators has substantially progressed during last years. The choice of a pediatric anesthesia ventilator needs to be led by multiple parameters: requirement, technical (pneumatic performance, velocity of halogenated or oxygen delivery), cost (purchase, in operation, preventive and curative maintenance), reliability, ergonomy,(More)
We compared the effects of systemic morphine on normal (heat and cold) pain and paradoxical burning pain evoked by the simultaneous application of innocuous warm and cold stimuli to the skin. Twelve healthy volunteers participated in a randomised, double-blind, cross-over study to compare the effects of intravenous administration of morphine (0.025 or(More)
BACKGROUND Global inverse correlation between BIS (bispectral index) and depth of anesthesia using sevoflurane has been documented in children in several studies under experimental conditions and in steady-state conditions during mechanically controlled ventilation. Because sevoflurane mask anesthesia combined with a peripheral nerve block is widely used in(More)
BACKGROUND AND OBJECTIVE The combination of non-opioid analgesic drugs, though widely used, has been rarely evaluated. The aim of this study was to compare the efficacy of propacetamol and the non-steroidal analgesic drug ketoprofen, alone or in combination, on pain relief after thyroid surgery performed using remifentanil. METHODS Ninety-seven patients(More)
