Clinical TrialValidation of a new respiratory inductive plethysmograph.
The respiratory inductive plethysmograph (RIP) can be used to monitor changes in end-expiratory lung volume (deltaEELV), and thus, used in intensive care when evaluating positive end-expiratory pressure (PEEP)-induced changes in lung volumes in order to optimise the ventilator settings. We validated the newest model of RIP (Respitrace Plus), both under laboratory and clinical conditions, and made a comparison with a previously validated RIP (Respigraph) in the measurement of tidal volume (V(T)), long-term EELV and PEEP-induced acute deltaEELV. ⋯ The new RIP is accurate enough for clinical and research purposes in the measurement of V(T). Semiquantitative measurements of acute deltaEELV can be done with accuracy sufficient for clinical use, but long-term deltaEELV monitoring is not possible. The new RIP should be kept on for several hours before measurements to minimise the drift.

Case Reports Clinical TrialComplaints related to respiratory events in anaesthesia and intensive care medicine from 1994 to 1998 in Denmark.
In Denmark, a National Board of Patients' Complaints (NBPC) was founded in 1988. This study analyses anaesthetic complaints related to adverse respiratory events filed at the NBPC from 1994 to 1998 to point out directions for possible preventive measures. ⋯ Complaints related to respiratory events reveal that inadequate anaesthetic and intensive care medicine treatment leads to patient damage and death. Preventive strategies should be directed at the development of guidelines for handling the difficult airway, education in the management of the difficult airway, instruction in the correct use of anaesthetic equipment, improvement of interpersonnel communication routines, as well as implementation of simulator training.

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.

Paracetamol (N-acetyl-p-amino-phenol) or acetaminophen has become the most widely used analgesic and antipyretic in children. However, there is a wide discrepancy between the extent to which paracetamol is used and the limited available pharmacological data in small infants. The purpose of this article is to present a review of the current literature regarding the use of paracetamol in neonates and infants with a particular emphasis on pharmacological issues. ⋯ The pharmacokinetics and pharmacodynamics of paracetamol differ substantially in neonates and infants from those in older children and adults; hence, dosing should be adjusted accordingly.
