Filter by:Different pain assessment methods have been proposed to evaluate analgesic efficacy after surgical operation. Pain is a subjective phenomenon. Patient did his pain self assessment. But, cooperation of the patient is limited by cultural differences, language barriers or residual effect of products used while general anesthesia. A lot of study were conducted to demonstrate and to quantify the pain after an operation. The aim will be dose analgesic treatment better without cooperation of the patient. This sudy concerns patients on the post anesthesia care units one hour after their arrival. They will have electrocardiogram and video-pupillometer.
The use of 100% oxygen during the induction of general anesthesia is always preferable to have enough time to secure the airway by endotracheal intubation, because preoxygenation with a low oxygen concentration may reduce the safe time for apnea. However, using a low oxygen concentration during preoxygenation might prevent the formation of atelectasis. There is still no clear conclusion about the best oxygen concentration for preoxygenation. Our study is designed to evaluate the safety of preoxygenation with 80%, 60%, 40%, 30% and 21% oxygen by the safe time for apnea during the induction of general anesthesia.
The purpose of this study is to evaluate whether carotid Doppler peak systolic velocity can be an easy to measure possible surrogate for echocardiographic measurement of aortic peak systolic velocity variation which is an index of fluid responsiveness in mechanically ventilated children intra-operatively.
Low-tidal volume ventilation is arising as a tool to optimize the ventilatory management and to improve clinical outcome in patients undergoing general anesthesia for abdominal surgery. A recent large randomized controlled trial failed to detect a significant difference between two different approaches for ensuring adequate lung recruitment (PEEP=12 cmH2O + scheduled recruiting maneuvers vs. PEEP 2 cmH2O) during protective ventilation. Thus, in patients undergoing open abdominal surgery and receiving low-tidal volumes, the effects of different positive end-expiratory pressure (PEEP) levels and recruiting maneuvers remain to be established. Design: prospective, cross-over, physiological trial. PURPOSE To assess the physiological effects of different PEEP levels with or without scheduled recruiting maneuvers in patients undergoing general anesthesia for open abdominal surgery and receiving low-tidal volume ventilation.
General anesthesia has been demonstrated to have a negative impact on lung function. Both surgery and patient position influence the perioperative lung function. Laryngeal mask airway (LMA) has been proved to be safe and efficient to maintain the airways patent during general anesthesia. Pressure support ventilation (PSV) with LMA is routinely used in clinical practice. The aim of the present trial is to characterize perioperative changes in lung volume, ventilation inhomogeneity and respiratory mechanics in patients in the lithotomy position and spontaneously breathing through LMA with and without PSV.
Mother spend a large amount of time with their children. It is assumed that mother contributes to their neurological development not only with visual stimuli, but also with auditory stimuli. A recent study revealed that prefrontal cortex can be activated in response to the self-name being spoken by the mother than by a stranger. Therefore, investigators suppose that recorded maternal voice can stimulate the pediatric patients and thereby fasten the emergence from general anesthesia.

The objective of the ANESPEDIA study is to describe in a pediatric population (aged from 4 to 8 years old) receiving elective surgery, the impact of general anesthesia on autonomic nervous system and their kinetics of early postoperative course (24 hours).
The purpose of this study is to determine whether Propofol and Sevoflurane affect the oxidative stress and apoptosis status in children undergoing hypospadias repair surgery.
