ReviewAnaesthetic implications of thoracoscopic surgery in children.
As the equipment and technique have improved, minimally invasive surgery is being applied to younger and younger children. With the advent of this valuable surgical technique, there are also specific modifications necessary in the anaesthetic technique. ⋯ The following article attempts to address and review the specific anaesthetic implications of thoracoscopic procedures in neonates, infants, and children including the preoperative evaluation, intraoperative care and monitoring, and postoperative issues including analgesia. The techniques of one-lung anaesthesia, commonly required for thoracoscopy, are reviewed as well as consideration of the adverse effects which can occur during thoracoscopy including inadvertent intravascular CO2 embolism.

Use of intravenous ketamine-midazolam association for pain procedures in children with cancer. A prospective study.
We evaluated the safety and efficacy of midazolam-ketamine association to control pain induced by diagnostic procedures in paediatric oncology patients. 226 procedures were carried out in 92 patients aged three days to 18 years. Drugs were given i.v. by an anaesthesiologist. Midazolam dose was 25 microg.kg-1 and ketamine 0. 5 to 2 mg.kg-1, depending on number and invasiveness of procedures. ⋯ Mean duration of sedation was ten min. No complication was observed and analgesia was considered satisfactory in 89 out of 92 patients. These results indicate that midazolam-ketamine is a safe and effective association in pain management for paediatric oncology patients and efficiently induces brief unconscious sedation with analgesia.

Clinical TrialAxillary brachial plexus block for perioperative analgesia in 250 children.
A cannula technique for axillary brachial plexus block in combination with general anaesthesia has been in use since 1994 for children undergoing surgical correction of congenital hand anomalies. During a 4-year period data were collected on 250 procedures in 185 patients of median age 3 years detailing the block technique and the intraoperative and postoperative analgesic requirements. ⋯ Postoperative pain was controlled in this series with oral analgesia in all but six patients who received parenteral codeine. It is proposed that a cannula technique is an effective and safe method of producing axillary brachial plexus block in children.

Comparative StudyComparison of three techniques for induction of anaesthesia with sevoflurane in children.
This study was designed to evaluate the clinical characteristics of three induction techniques using sevoflurane in children scheduled for tonsillectomy: incremental induction with sevoflurane(2,4,6,7%) in 100% O2 (group IC-O2; n=23); induction with high concentration of sevoflurane in 100% O2 (group HC-O2; n=22); and induction with high concentration of sevoflurane in a mixture of O2:N2O(50:50) (group HC-N2O; n=20). Induction was well accepted and well tolerated in most children. The addition of nitrous oxide resulted in faster loss of consciousness (P< 0.001) compared to the other induction techniques and in a tendency for reduced excitement compared with the same rapid technique without nitrous oxide (P=0.053). ⋯ Changes were maximal at two min after the beginning of induction in the three groups. SAP and HR values were back to baseline values at the time of tracheal intubation. In conclusion, the addition of nitrous oxide to a high sevoflurane concentration decreases the time to loss of eyelash reflex, tends to reduce the incidence of excitement and is not associated with an increased incidence of respiratory complications even in patients with obstructive airway.

Case ReportsSome vagaries of neonatal lumbar epidural anaesthesia.
Regional anaesthesia and analgesia offer unique advantages of reduction in general anaesthesia requirements and the demands on NICU resources while improving the general outcome. We assessed the feasibility of continuous lumbar epidural analgesia in 20 neonates for various major surgical procedures lasting from 60-260 min. The babies were aged 18 h to 34 days. ⋯ They were awake but comfortable at the time of extubation. There were no complications due to the technique. Subsequent to this study, epidural analgesia either by lumbar or caudal route has become the routine in our hospital for all major thoraco-abdominal surgical procedures in neonates.
