Effect of combined mouth closure and chin lift on upper airway dimensions during routine magnetic resonance imaging in pediatric patients sedated with propofol.
BACKGROUND In pediatric patients, obstruction of the upper airway is a common problem during general anesthesia. Chin lift is a commonly used technique to improve upper airway patency. However,… Expand
Respiratory Reflex Responses of the Larynx Differ between Sevoflurane and Propofol in Pediatric Patients
Background:The effects of anesthetics on airway protective reflexes have not been extensively characterized in children. The aim of this study was to compare the laryngeal reflex responses in… Expand
Effect of common airway manoeuvres on upper airway dimensions and clinical signs in anaesthetized, spontaneously breathing children.
Chin lift, jaw thrust and these manoeuvres combined with continuous positive airway pressure (CPAP) can be used to improve the patency of the upper airway during general anaesthesia. We used video… Expand
Decrease of Functional Residual Capacity and Ventilation Homogeneity after Neuromuscular Blockade in Anesthetized Young Infants and Preschool Children

Background: Based on age-dependent differences in pulmonary mechanics, the effect of neuromuscular blockade may differ in infants compared with older children. The aim of this study was to determine… Expand
Is the end-tidal partial pressure of isoflurane a good predictor of its arterial partial pressure?
End-tidal partial pressure of isoflurane (PE'iso) may be used as a measure of anaesthetic depth. During uptake, an arterial partial pressure (Paiso) which is considerably less than PE'iso… Expand
Difficult intubation in paediatrics
Optimal oxygenation and ventilation in anaesthetized or critically ill patients are crucial and because of the increased oxygen consumption and decreased oxygen reserve, hypoxaemia occurs more… Expand
Pulse oximetry in methaemoglobinaemia
The results of pulse oximetry saturation in a patient with a high level of methaemoglobinaemia, who subsequently underwent intravenous methylene blue treatment, are presented. The reasons for the… Expand
Effect of airway opening manoeuvres on thoraco-abdominal asynchrony in anaesthetized children.
Thoraco-abdominal asynchrony is frequently encountered during inhalation anaesthesia in children with adenotonsillar hypertrophy causing an upper airway obstruction. The study goal was to evaluate… Expand
The Effects of Common Airway Maneuvers on Airway Pressure and Flow in Children Undergoing Adenoidectomies

Obstruction of the upper airway occurs frequently in anesthetized, spontaneously breathing children, especially in those with adenoidal hyperplasia. To improve airway patency, maneuvers such as chin… Expand
Control of end-tidal halothane concentration. Part B: Verification in dogs.
Conventional anaesthetic techniques do not allow for the automatic control of end-tidal halothane concentration and, therefore, brain concentration cannot be predicted. In this study, eight dogs were… Expand
