Randomized Controlled Trial Clinical TrialMyopexy (Faden) results in more postoperative vomiting after strabismus surgery in children.
Strabismus correction in children is associated with a high incidence of postoperative nausea and vomiting. The purpose of this prospective, double-blind study was to examine the influence of the surgical method for correction of squint on the incidence of postoperative vomiting. ⋯ The surgical method used for strabismus correction in children has a great influence on the incidence of postoperative vomiting. The Faden operation is associated with a very high incidence of postoperative vomiting; this particular group of patients has to be considered as a high risk group for postoperative vomiting and deserves an antiemetic prophylaxis.

Randomized Controlled Trial Comparative Study Clinical TrialMeasuring patient satisfaction with anaesthesia: perioperative questionnaire versus standardised face-to-face interview.
Patient satisfaction represents an essential part of quality management. Measuring the degree of patient satisfaction can be achieved with a variety of tools such as postoperative visits and patient questionnaires. The primary aim of this study was to quantify the degree of patient satisfaction with anaesthesia. A secondary aim was to compare the questionnaire technique with standardised face-to-face interviewing. ⋯ The standardised interview may be more suited to determine patient satisfaction than a questionnaire. Quality improvements are possible for emergence from anaesthesia, postoperative pain therapy, and the treatment of postoperative nausea and vomiting.

Ventilation-perfusion distributions in different porcine lung injury models.
Acute lung injury is characterized by hypoxemia which may be caused by hypoventilation, ventilation-perfusion (V(A)/Q) mismatch, intrapulmonary shunting and oxygen diffusion impairment. The multiple inert gas elimination technique (MIGET) allows analysis of these four causes of hypoxemia and is therefore the most comprehensive approach to investigate blood gas abnormalities. Using MIGET, we studied whether specific patterns of gas exchange abnormalities occur in different lung injury models and whether gas exchange abnormalities can be related to pathogenic aspects of lung injury. ⋯ Shunt and ventilation-perfusion mismatch fully explain the gas exchange disturbances observed in our lung injury models. Although V(A)/Q distributions can be related to pathogenic aspects of the three study groups, we did not observe specific V(A)/Q patterns which allow diagnosis of the type of lung injury from a recovered V(A)/Q distribution.

Randomized Controlled Trial Clinical TrialThe influence of halothane, isoflurane and sevoflurane on rocuronium infusion in children.
Rocuronium is a non-depolarizing neuromuscular blocking agent with intermediate duration of action and without significant cumulative properties, suitable for continuous infusion. This study was designed to determine the infusion requirements in children under nitrous oxide and fentanyl, halothane, isoflurane or sevoflurane anaesthesia. ⋯ The rocuronium infusion rate required to maintain stable 90-99% T1 depression was reduced by approximately 20% with halothane and isoflurane anaesthesia, and by 50% with evoflurane anaesthesia when compared to fentanyl-nitrous oxide anaesthesia. Significant patient-to-patient variability of infusion rate makes monitoring of neuromuscular transmission necessary.
