The expiratory time (Te) and the rate of lung emptying in expiration are important determinants of functional residual capacity (FRC) in infants. In order to determine whether these factors also influence FRC in children during anesthesia, 20 preschool children were studied, 10 while receiving ketamine, and 10 during halothane anesthesia. Te was measured during quiet breathing and the passive expiratory time constant (tau) was determined from the passive expiratory flow volume (V/V) curve… Expand
Respiratory Mechanics and Intrinsic PEEP during Ketamine and Halothane Anesthesia in Young Children
TLDR
It was concluded that, in children anesthetized with ketamine, Crs is significantly greater than that in childrenAnesthetizing with halothane, and the resultant prolongation of ± and decreased Te/τ with ketamines anesthesia lead to increased PEEPi. Expand
Anaesthesia and the ventilatory system in infants and young children.
TLDR
It is not possible in a single review article to cover all aspects of anaesthesia and the respiratory system in infants and young children, but those matters which are of particular relevance to the anaesthetist, and those in which there have been recent developments are concentrated. Expand
Perioperative functional residual capacity
  • R. Wahba
  • Medicine
  • Canadian journal of anaesthesia = Journal canadien d'anesthesie
  • 1991
TLDR
Both FRC and vital capacity are reduced following abdominal and thoracic surgery in a predictable pattern and there is no real difference among the various methods of active lung expansion in terms of the speed of restoration of lung function, or in preventing postoperative atelectasis/pneumonia.

Effects of anaesthesia on paediatric lung function.
TLDR
This review aims to give a comprehensive overview of the effects of anaesthesia on respiration in children by focusing on the impact of the different components of anaesthetic, patient positioning and procedure-related changes on respiratory physiology. Expand
