Randomized Controlled Trial Comparative Study Clinical TrialComparison of three techniques for internal jugular vein cannulation in infants.
Central venous cannulation allows accurate monitoring of right atrial pressure and infusion of drugs during the anaesthetic management of infants undergoing cardiopulmonary bypass. In this prospective, randomized study, we compared the success and speed of cannulation of the internal jugular vein in 45 infants weighing less than 10 kg using three modes of identification: auditory signals from internal ultrasound (SmartNeedle, SM), external ultrasound imaging (Imaging Method, IM) and the traditional palpation of the carotid pulsation and other landmarks (Landmarks Method, LM). ⋯ The incidence of carotid artery puncture and the success rate were not significantly different among the three groups. In infants, a method based on visual ultrasound identification (IM) of the internal jugular vein is more precise and efficient than methods based on auditory (SM) and tactile perception (LM).

Randomized Controlled Trial Comparative Study Clinical TrialA comparison of rectal and intramuscular codeine phosphate in children following neurosurgery.
Codeine is frequently used for postoperative analgesia in children. Intramuscular injections are not ideal and the rectal route may be preferable. We compared rectal and intramuscular codeine administered following neurosurgery. 20 children (over 3 months) undergoing elective neurosurgical procedures, were randomized to receive either rectal or intramuscular codeine phospate (1 mg.kg-1) at the end of the procedure. ⋯ The plasma codeine levels were significantly greater at 30 and 60 min following intramuscular injection, and were associated with slightly better analgesia scores, but did not reach statistical significance. However, the peak plasma level occurred at similar times in both groups. Codeine is absorbed as rapidly via the rectal route compared with the intramuscular route but the peak levels are lower.

Clinical Trial Controlled Clinical TrialPreoperative psychological preparation for children undergoing ENT operations: a comparison of two methods.
A psychological preparation programme was developed for outpatient surgery in children. The purpose of this study was to determine if the programme could increase retrieval of information and reduce anxiety prior to ENT surgery. After ethical committee approval, 160 children and their parents were included. ⋯ The parents experienced watching their child fall asleep during induction of anaesthesia as most negative, followed by the insertion of the i.v.-needle. Parents also reported more satisfaction and less anxiety after having received specific information and preparation preoperatively. It was concluded that this preoperative preparation programme is useful in all age groups with regard to information, while alleviation of anxiety and fear was seen mainly among the younger children with previous experience of anaesthesia.

Randomized Controlled Trial Comparative Study Clinical TrialSerum glutathione S-transferase alpha as a measure of hepatocellular function following prolonged anaesthesia with sevoflurane and halothane in paediatric patients.
We studied the effects of prolonged anaesthesia (4.3-7.7 h) with sevoflurane and halothane on hepatic function in 14 paediatric patients. Hepatic function was assessed using serum concentrations of liver-specific glutathione S-transferase alpha (GSTA) before and 0, 3 and 15 h after the end of anaesthesia. A transient significant increase in GSTA over baseline was observed in the sevoflurane group, but not in the halothane group, and the difference between the groups was not significant. These data suggest that, although statistically insignificant, the use of sevoflurane for prolonged anaesthesia in paediatric patients is more likely than halothane to be involved in damage to hepatic function.

Randomized Controlled Trial Clinical TrialAnalgesic efficacy of ketorolac 0.5% ophthalmic solution (Accular) in paediatric strabismus surgery.
This prospective double-blind study was designed to assess the analgesic efficacy of ketorolac 0.5% ophthalmic solution compared with placebo in 30 healthy children undergoing extraocular muscle recession for correction of strabismus. After paracetamol 20 mg.kg-1 preoperatively, a standard anaesthetic was given. ⋯ This study did not demonstrate improved postoperative analgesia when topical ketorolac eye drops were given in addition to paracetamol. This observed lack of efficacy may reflect difficulties in the use of CHEOPS and FPS in this age group with this pain model.
