Case ReportsPerioperative care of the child with the Johanson-Blizzard syndrome.
The Johanson-Blizzard Syndrome (JBS) is an autosomal recessive disorder with a characteristic phenotype, including dwarfism, a beaked nose with aplastic alae nasi, a high forehead, mid-line ectodermal scalp defects with sparse hair and absent eyelashes/eyebrows, prominent scalp veins, low set ears, a large anterior fontanelle, micrognathia, thin lips, absent permanent dentition and microcephaly. In addition to the characteristic facial features, associated conditions include congenital heart disease, exocrine/endocrine pancreatic dysfunction, hypothyroidism, hypopituitarism, mental retardation, sensorineural hearing loss and vesico-ureteral reflux. A case is presented and the potential anaesthetic implications of this syndrome are discussed.

Randomized Controlled Trial Clinical TrialPropofol anaesthesia and metabolic acidosis in children.
We aimed to investigate the effect of propofol infusion anaesthesia on acid-base status and liver and myocardial enzyme levels of children during short-term anaesthesia. ⋯ In these healthy patients, short-term use of propofol did not result in significant acidaemia, nor alterations in hepatic or myocardial enzyme levels.

The effectiveness and safety of spinal anaesthesia in the pyloromyotomy procedure.
Hypertrophic pyloric stenosis is a relatively common disorder of the gastrointestinal tract in infancy, causing projectile vomiting and metabolic abnormalities. Surgical management in the form of pyloromyotomy under general anaesthesia has been reported as safe for relieving the obstructed bowel. A number of studies have demonstrated the advantages of spinal anaesthesia over general anaesthesia in high risk infants undergoing minor infraumbilical surgery. The purpose of this study was to evaluate spinal anaesthesia as an alternative option to general anaesthesia in infants undergoing pyloromyotomy. ⋯ This study proposes that spinal anaesthesia is an alternative option to general anaesthesia in infants undergoing pyloromyotomy, and should be considered in infants undergoing pyloromyotomy.

Combining low inspired oxygen and carbon dioxide during mechanical ventilation for the Norwood procedure.
Staged reconstruction has become the preferred approach for treating neonates with hypoplastic left heart syndrome (HLHS). The haemodynamic instability of a single ventricle providing blood flow in parallel to the systemic and the pulmonary circulation, combined with the effects of cardiopulmonary bypass (CPB), results in precarious perioperative conditions. The two ventilatory manoeuvres commonly used for increasing pulmonary vascular resistance are (i) decreasing the fraction of inspired oxygen to < 0.21 and (ii) adding carbon dioxide (CO2) to the ventilatory circuit. Whether molecular nitrogen (N2) or CO2 is used in these situations is a matter of physician and institutional preference. The effect of the two modalities in combination has not been studied in depth. ⋯ Low inspired oxygen and CO2 have an additive vasoconstrictive effect on the pulmonary vessels. The use of both of these ventilatory manoeuveres is less effective postoperatively compared with the prebypass period.
