A new regimen for postoperative analgesia after thoracic surgery is proposed. Eight children received an interpleural infusion using bupivacaine 0.1% in a regimen from 0.5 ml.kg-1.h-1 up to 1 ml.kg-1.h-1, for 48 h according to the pain scores. The plasma levels after 24 h and 48 h were measured as well as the pleural level and in two patients the free fraction of plasma bupivacaine and the plasma PPX (a metabolite of bupivacaine) and one patient the orosomucoid (main plasma protein involved in bupivacaine protein binding) were also measured pre and postoperatively. The results shows the safety of such a regimen, for two days of postoperative analgesia.

Postoperative nausea and vomiting in paediatric surgical inpatients.
A prospective study of postoperative nausea and vomiting (PONV) was conducted in 415 children presenting for inpatient surgery. The overall incidence of PONV was 18.1%). The highest incidence was in children undergoing ENT procedures and increased with age. Avoidance of intraoperative opioids and the use of local anaesthesia and/or non-steroidal anti-inflammatory drugs reduced the incidence of nausea and vomiting postoperatively.

The safety of continuous pleural lignocaine after thoracotomy in children and adolescents.
Several studies have proven pleural bupivacaine effectively provides postthoracotomy analgesia for both children and adults. When 0.25% bupivacaine is administered as a continuous infusion or repeated bolus, serum bupivacaine levels frequently approach the toxic range. The hazards of bupivacaine toxicity are more difficult to monitor, especially in children who may not report symptoms of local anaesthetic toxicity. ⋯ Seven patients had lignocaine levels that exceeded 5 micrograms.ml-1 and no patient manifested symptoms of systemic toxicity. This study shows that the administration of pleural lignocaine is a safe method of providing postthoracotomy analgesia. Lignocaine infusions in the dosage range of 20 to 40 micrograms.kg-1.min-1 rarely produce toxic levels, and monitoring of lignocaine levels every 12 h is an effective method of screening for toxicity.

Preoperative evaluation of the cervical spine in children with trisomy-21: results of a questionnaire study.
Atlantoaxial subluxation (AAS) is a form of cervical spine instability predominantly found in persons with Trisomy-21. Several case reports describe the occurrence of acute AAS in the perioperative period. Some authors have recommended cervical spine radiographs prior to elective surgery in all children with Trisomy-21. ⋯ Approximately half of the respondents would attempt to maintain the head and neck in a neutral position for either asymptomatic (42%) or symptomatic (55%) patients. We conclude that the majority of respondents base their preoperative evaluation of the cervical spine on the signs and symptoms of the patient. This is supported by the literature reviewed, but is contrary to the recommendations made in some case reports.

Case ReportsThe laryngeal mask airway for fibreoptic bronchoscopy in children.
A size 2 laryngeal mask airway (ID 7 mm) was used for general anaesthesia during fibreoptic bronchoscopy in a six-year-old child. The mask permitted the use of an adult bronchoscope with an external diameter of 5 mm. Throughout bronchoscopy, adequate controlled ventilation could be achieved easily without excessive air leak or airway resistance; the Spo2 was always > 97%, and the end-tidal Pco2 ranged between 3.9-4.5 kPa (30-35 mmHg).
