Codeine is frequently used for postoperative analgesia in children. Intramuscular injections are not ideal and the rectal route may be preferable. We compared rectal and intramuscular codeine administered following neurosurgery. 20 children (over 3 months) undergoing elective neurosurgical procedures, were randomized to receive either rectal or intramuscular codeine phospate (1 mg.kg-1) at the end of the procedure. Serum levels of codeine and morphine were assayed at intervals following administration (0, 30, 60, 120, 240 min). Fentanyl was the intraoperative analgesic and postoperative rescue analgesia was paracetamol, diclofenac and intramuscular codeine. The Children's Hospital of Eastern Ontario Pain Scale was used to assess analgesia. Peak codeine levels in both groups were observed at 30 min and morphine levels were consistently low. The plasma codeine levels were significantly greater at 30 and 60 min following intramuscular injection, and were associated with slightly better analgesia scores, but did not reach statistical significance. However, the peak plasma level occurred at similar times in both groups. Codeine is absorbed as rapidly via the rectal route compared with the intramuscular route but the peak levels are lower.
While there are many similarities with nurse consultants in adult practice, one major difference was the nurse consultant role in supporting families when caring for children and young people. This meant having a three-way communication style: with the family, the child/young person, and other healthcare professionals. This communication style was observed by the research fellow in participant observation of the nurse consultants undertaking clinical care and is described further in the analysis of the role.
This study confirmed that the assessment tools for evaluation of children with LMMC are inconsistent, often vague and poorly validated. This compromises the ability of clinicians who care for them to compare studies across centres for both treated and untreated children. We have sought to highlight those criteria which are relevant, measurable and reproducible and which might be combined into an easily applied assessment.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
