Bispectral index monitoring in children undergoing mild hypothermic cardiopulmonary bypass.
In this prospective, cohort study of 15 children (median age 7.7 years, range 4.9-16.5 years) undergoing atrial septal defect repair, we evaluated changes in the Bispectral index (BIS) as a potential monitor of level of consciousness during cardiac anaesthesia. ⋯ The increase in BIS during the rewarming phase could reflect an increase in conscious level, and is consistent with the reported risk for awareness during this phase of cardiac surgery.

Comparative StudyIs the sitting or the prone position best for surgery for posterior fossa tumours in children?
The aim of this study was to compare complications in children operated for posterior fossa tumours in the sitting position with those in the prone position. ⋯ PFT surgery in the sitting position in children is not associated with an increased number or severity of perioperative complications, while the postoperative course appears better in this position.

Impact of an antiemetic protocol on postoperative nausea and vomiting in children.
The objective of the study was to demonstrate a decreased incidence of postoperative nausea and vomiting (PONV) in children through the use of an antiemetic protocol. PONV was recorded in children (1.5-15 years) after inpatient surgery under general anaesthesia in a prospective, interview based survey. Group 1 consisted of children having surgery 1 month before the introduction of a formalized antiemetic protocol and group 2, 2 months after its introduction. ⋯ Patient satisfaction was high in both groups (85% versus 90%). The introduction of a postoperative antiemetic protocol improved prescribing frequency. This resulted in a decreased incidence of moderate to severe PON and a reduction in the number of patients with repeated nausea.

Determination of the median effective concentration (EC50) of propofol during oesophagogastroduodenoscopy in children.
Propofol is commonly used to provide anaesthesia for children undergoing oesophagogastroduodenoscopy (OGD). Despite this, the plasma concentration-response relationships for propofol used in this setting have not been established. ⋯ The plasma propofol concentration associated with adequate anaesthesia for OGD in 50% of unpremedicated children is 3.55 microg.ml(-1). This concentration is higher than that required for OGD in adult patients.

We performed a bench experiment to investigate the extent of start-up delays in fluid delivery for four different syringe pumps after initially placing the infusion syringe in the syringe pump. ⋯ Syringe pump design affects start-up delay times because of free play of the syringe. These delays can be eliminated by a start-up bolus of 2 ml prior to connecting the infusion line to the patient.
