Case ReportsAnaesthetic management during awake craniotomy in a 12-year-old boy.
We present our approach to the preoperative preparation and anaesthetic management for awake craniotomy in a 12-year-old boy. Management included conscious sedation with a propofol infusion plus local anaesthetic infiltration of the scalp, periosteum, and dura. The complications which may be encountered during such procedures and their treatments are reviewed.

Case ReportsRepair of ventricular septal defect in a child with severe pulmonary hypertension--response to inhaled nitric oxide.
Nitric oxide (NO), was administered successfully, to a child with severe pulmonary hypertension, following surgical repair of a large ventricular septal defect. Inhalation of NO, 20-25 parts per million (ppm) was continued for 24 h, resulting in mean pulmonary artery pressure (PAP) of 25 mmHg and permitting a reduction in both ventilatory and inotropic support. ⋯ An immediate and dramatic increase in PAP occurred. A similar pattern resulted on further attempts, demonstrating the extreme sensitivity of the pulmonary vasculature to the effects of inhaled low dose NO and the selectivity of the response.

Case ReportsRespiratory depression following epidural morphine in an infant of three months of age.
Epidural administration of combinations of opioids and a local anaesthetic provides prompt and effective analgesia and is increasingly used in paediatric anaesthesia. However, respiratory depression by rostral spread of opioid in the CSF is by far the greatest concern after epidural morphine. An infant of three months of age underwent portoenterostomy (Kasai's operation) for extrahepatic biliary duct atresia. ⋯ Low arterial saturation (SpO2) was detected by pulse oximetry and confirmed by blood gas analysis. An intravenous bolus of 5 micrograms.kg-1 naloxone followed by a 3-h infusion of 2 micrograms.kg-1.h-1 resulted in complete reversal of signs and symptoms of respiratory depression. Epidural opioids should be limited to paediatric patients admitted to specialized recovery units for the first postoperative day.

Case ReportsBilateral continuous paravertebral block used for postoperative analgesia in an infant having bilateral thoracotomy.
We describe the successful postoperative pain management in an 11-month-old infant who underwent bilateral thoracotomy, using continuous infusions of bupivacaine into two directly placed paravertebral catheters. Haemodynamic parameters and pain scores were measured 1-2 h for 60 h while the infusions were continued and, intermittently, blood samples were taken for subsequent measurement of serum bupivacaine concentrations. ⋯ There were no adverse haemodynamic consequences or complications relating to either catheter placement or drug infusions. Serum concentrations of bupivacaine remained below toxic levels throughout the study period, though accumulation did occur.

Case ReportsA fibreoptic intubation technique for children with mucopolysaccharidoses using the laryngeal mask airway.
Children with mucopolysaccharidoses present the anaesthetist with both a difficult airway and often an impossible intubation using conventional techniques. A technique for airway management and tracheal intubation is described utilizing the Brain laryngeal mask airway, the fibreoptic bronchoscope, a guide wire and a ureteral dilator. Two case reports of children with mucopolysaccharidoses are presented who were managed successfully with this technique. The advantages of the technique are discussed.
