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.

Case ReportsSpinal anaesthesia and meningitis in former preterm infants: cause-effect?
Meningitis associated with spinal anaesthesia is a rare but well-known complication. We report on a case of fatal bacterial meningitis following spinal anaesthesia in a former preterm infant. ⋯ Former preterm infants represent a high-risk population because of their susceptibility to group B streptococcal meningitis at this age as documented in a second case. Therefore we discuss whether meningitis was consequential or coincidental with spinal anaesthesia and could have been prevented by more comprehensive preoperative laboratory screening or prophylactic antibiotics.

Comparative StudyThe influence of breathing system filters on paediatric capnography.
Breathing system filters are in common use during paediatric anaesthesia. Expired gas sampling from the patient side of these filters may contaminate and saturate the sampling line, while sampling from the machine side may cause underestimation of end-tidal carbon dioxide (PECO 2). ⋯ PECO 2 was higher at the patient side of the filter in both ventilated and spontaneously breathing groups (P<0.002 for each). The bias in measuring at the machine side of the filter was significantly greater in the spontaneously breathing children as compared with the mechanically ventilated children (-1.8 vs -0.7 kPa; P<0.004).

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.
