We describe a technique involving the use of a laryngeal mask airway, fibreoptic bronchoscope and a guide wire to manage the intubation of a child who was known to be a difficult intubation. The technique is simple, atraumatic, permits the use of an adult bronchoscope for infants and children, and allows control of the airway and ventilation throughout the period of intubation.

Acute toxicosis in two dogs associated with etomidate-propylene glycol infusion.
Etomidate, formulated in propylene glycol, was used as the primary anesthetic agent in two dogs (No. 1 and 2) and etomidate, formulated in saline, was used as the primary anesthetic agent in an additional 20 dogs, while developing a canine model for baroreceptor sensitivity testing. Dogs 1 and 2 had signs of acute toxicosis after infusion of etomidate in propylene glycol. Dog 1 received less total etomidate than did dog 2, 5.9 mg/kg vs 15.8 mg/kg, respectively. ⋯ After supportive treatment, dog 2 regained consciousness and hemodynamic variables improved within 12 h. None of the additional 20 dogs that received infusion of etomidate in saline had any clinical adverse effects, suggesting a causal relationship between the etomidate-propylene glycol formulation and the adverse effects in dogs 1 and 2. Although etomidate may be useful in designing cardiovascular models under general anesthesia, such complications may warrant use of a different etomidate formulation in the dog when the agent is administered at these infusion rates.

Case Reports
[Fiberscopic intubation under general anesthesia for children with Goldenhar syndrome].
Goldenhar syndrome is characterised by an eye abnormality such as epibulbar dermoid and lipoma, associated with ear, mandibular, and/or vertebral anomalies. It is well documented that difficult intubation in patient with this syndrome may be expected because of mandibular hypoplasia and limitation of neck movement resulting from vertebral anomalies. We report anesthetic management of two children with Goldenhar syndrome, 9 and 14-year-old. ⋯ By using this adapter, under sevoflurane/nitrous oxide anesthesia with vecuronium, we could successfully intubate with a 6 mm spiral tube through the nostril without any major problems. Anesthesia and surgery went uneventfully, and no postoperative complications were noted. We confirmed that our newly developed mask adapter for fiberoptic bronchoscopy is as useful for children with difficult intubation as for adults.

Comparative Study[Anesthesiological problems in magnetic resonance].
A prospective study was carried out on 68 patients examined with Magnetic Resonance Imaging (MRI) under general anesthesia. Mean patients age was 10 years (range: 9 days to 77 years). MRI was performed with a 1.5 T superconductive magnet and different anatomical regions were studied: the brain in 63 cases, the lumbar spine in 3, the cervical spine in 1 and finally the upper abdomen in 1 patient. ⋯ Minor complications occurred in 5 more patients. Image quality was excellent in 75% of cases, while few movement artifacts were observed in the extant 25%. To conclude, isoflurane anesthesia is a safe, effective and efficient type of sedation for the patients to be submitted to MRI which can be used also on an outpatient basis.
