Case ReportsPerioperative considerations in a newly described subtype of congenital long QT syndrome.
An infant with a newly-described subtype of congenital long QT syndrome is presented, along with her perioperative management on three separate occasions. During each anaesthetic characteristic arrhythmias occurred. The available literature and rational approaches to these high risk patients are reviewed.

A simple homemade lighted stylet for neonates and infants: a description and case report of its use in an infant with the Pierre Robin anomalad.
The glossoptosis and micrognathia associated with Pierre Robin anomalad can make tracheal intubation by conventional laryngoscopy quite difficult. Lighted stylets may be helpful in the successful intubation of infants with this anomalad, but those currently available that are small enough to accommodate 3.0 mm ID tracheal tubes have two major drawbacks limiting their utility: an insufficiently rigid stylet component and a nonadjustable, overly bright light. We describe a lighted stylet that can be easily assembled in the operating room which overcomes these problems and allowed us to successfully intubate a six-day-old with severe Pierre Robin anomalad.

Case ReportsMassive blood loss during tonsillectomy in a child with congenital venous malformation.
Tonsillectomy and adenoidectomy have become frequently performed outpatient procedures and are generally considered to have a low morbidity profile. Postoperative haemorrhage remains a rare but important complication, while intraoperative uncontrollable bleeding is extremely uncommon. ⋯ Preoperative/preanaesthetic nasopharyngoscopic exam and magnetic resonance imaging did not reveal vascular prominence of the tonsils. Preoperative consideration of angiography or magnetic resonance angiography may be prudent to avoid this potentially fatal complication.

Mivacurium is the only available short-acting nondepolarizing muscle relaxant in clinical use. It is a bis-quaternary benzylisoquinolinium ester hydrolysed by plasma-cholinesterase into inactive compounds. The ED50 and ED95 in children are about 50 μg·kg-1 and 90 μg·kg-1 respectively. ⋯ Cutaneous flushes from histamine release are commonly seen with the larger doses of mivacurium; however, the associated hypotensive effects are minimal and counteracted by the tracheal intubation. The duration of action of mivacurium is prolonged in patients with cholinesterase deficiency. Mivacurium's neuromuscular effects can be satisfactorily antagonized by edrophonium or neostigmine.

Diclofenac vs oxybuprocaine eyedrops for analgesia in paediatric strabismus surgery.
Forty children undergoing strabismus surgery as day patients were randomly allocated to receive oxybuprocaine 0.4% eyedrops or 0.1% diclofenac eyedrops for perioperative analgesia. A non-invasive anaesthetic technique using the reinforced laryngeal mask airway was used. The study demonstrated that both topical analgesics provided good to excellent analgesia and the anaesthetic technique was associated with a relatively low incidence of nausea and vomiting. Complications were limited to two children who were admitted with persistent postoperative nausea and vomiting.
