Efficacy and complications of morphine infusions in postoperative paediatric patients.
The aim of the study was to evaluate the efficacy and the incidence of clinically significant adverse drug reactions (ADRs) in paediatric patients receiving continuous intravenous morphine infusions for acute postoperative pain. Definitions were established for ADRs and data were collected in an immediately retrospective fashion for a maximum of 72 h in 110 patients >/=5 three months of age (0.3-16.7 years) receiving morphine infusions and admitted to a general ward over a three month convenience sampling period. Inadequate analgesia occurred in 65.5% of patients during the first 24 h of therapy and occurred most frequently in patients with infusion rates of 20 microg.kg-1.h-1 or less. ⋯ The most common ADRs associated with morphine infusions were inadequate analgesia (in the first 24 h) and nausea/vomiting. There were no cases of respiratory depression. Methods of avoiding initial inadequate analgesia and treating nausea and vomiting associated with morphine infusions are needed.

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.

Seventy-two cases of pyloric stenosis treated in our institution in the last five years were reviewed in an attempt to determine the need for postoperative analgesia after pyloromyotomy in infants. All children had their wound infiltrated with a mean dose of 2.16+/-1.43 mg x kg(-1) of bupivacaine, and first analgesia was required 9.12+/-8.04 h after surgery. ⋯ In conclusion, there was a low consumption of analgesics after pyloromyotomy. Furthermore, infiltration of the wound appeared to be beneficial since time to administration of first postoperative analgesia was delayed.

Randomized Controlled Trial Clinical TrialIncidence of nausea and vomiting in children after strabismus surgery following desflurane anaesthesia.
In a prospective, randomized parallel study, 60 ASA I-III children aged 1-17 years, scheduled for elective strabismus surgery, were anaesthetized with desflurane without prophylactic antiemetic medication. The objective of the study was to determine the incidence of postoperative nausea and vomiting after general anaesthesia with desflurane. To decide whether nitrous oxide further influences these symptoms, the patients were randomly assigned to two groups of 30 patients each. ⋯ No statistical correlation was found between the incidence of postoperative emesis and the administration of nitrous oxide or the duration of general anaesthesia. Instead, the incidence of vomiting was 2.5-fold higher when surgery was performed on both eyes compared with one eye. The relatively low incidence of postoperative nausea and vomiting, as well as the quick recovery from anaesthesia, permitting an early discharge from the postoperative care unit to the ward, show desflurane to be a suitable volatile anaesthetic in strabismus surgery in children.

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.
