    Notes: Feldene MeltTM (piroxicam) is commonly used for analgesia following day case surgery. The manufacturer's recommended paediatric dose is 0.4 mg.kg−1 once daily. In children, plasma piroxicam levels of 3–5 μg.ml−1 are associated with effective analgesia. However, in adults a single dose of 20 mg piroxicam (0.4 mg.kg−1 for a 50-kg adult) produces plasma levels of only 1.5–2.2 μg.ml−1. We therefore studied plasma levels achieved by 0.4 mg.kg−1 or 1.0 mg.kg−1 piroxicam in 22 children aged between 3 and 16 years, undergoing elective orthopaedic surgery, in order to investigate the adequacy of single dosing. The first 12 patients received 0.4 mg.kg−1 Feldene MeltTM pre-operatively. Following assay of plasma piroxicam levels, a further 10 patients received 1.0 mg.kg−1 Feldene MeltTM. In both groups, five blood samples were taken at 2-hourly intervals. The mean (95% CI) piroxicam level following 0.4 mg.kg−1 was 2.90 (2.33–3.54) μg.ml−1, compared to 5.87 (4.58–7.16) μg.ml−1 following 1.0 mg.kg−1 (p = 0.0003).

    Notes: Background: Ketamine has an opioid sparing effect following surgery in adults. This study investigated whether a similar effect is seen following appendicectomy in paediatric patients.Methods: Seventy-five ASA 1 or 2 children aged 7–16 years were recruited, and randomly allocated to one of three groups. Following a standard anaesthetic for appendicectomy, all were prescribed patient controlled analgesia (PCA) morphine with paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDS) as required for postoperative analgesia. In addition the control group received a saline infusion postoperatively, the ketamine bolus group received 500 μg·kg−1 intravenous (i.v.) ketamine preincision and a saline infusion postoperatively, and the ketamine infusion group received 500 μg·kg−1 i.v. ketamine preincision and a ketamine infusion at 4 μg·kg−1 min−1 postoperatively. Morphine consumption, rescue analgesia requirement and side-effects were recorded postoperatively.Results: There was no difference in morphine consumption between the groups. The ketamine infusion group required more doses of rescue analgesia and reported more side-effects than the control group. Five patients, all in the ketamine infusion group, reported hallucinations.Conclusions: In this paediatric population intravenous ketamine did not have a morphine sparing effect. The increased incidence of side-effects, especially hallucinations, reported by patients given a ketamine infusion may limit the further use of postoperative ketamine in children.

    Notes: Tensile strength of 2-cm, full-thickness, surgically incised porcine skin wounds sealed with fibrin sealant was enhanced compared to conventionally sutured wounds at 6 hours postwounding, but was significantly reduced after 3 days. Supplementation of fibrin sealant with transforming growth factor-β2 (TGF-β2) reversed the inhibitory effects of fibrin sealant on tensile strength at 3 days, and enhanced tensile strength at 7 days compared to suture or fibrin sealant alone. By 14 days, the tensile strengths of all wounds were similar, although wounds treated with fibrin sealant supplemented with TGF-β2 showed a small, but statistically significant, improvement in wound strength compared to wounds treated with fibrin sealant alone. Histological assessment at day 7 revealed significant remnants of fibrin sealant at the wound site following fibrin sealant treatment alone, while wounds treated with fibrin sealant supplemented with TGF-β2 or suture exhibited fibroblast infiltration and extracellular matrix deposition. At day 7, TGF-β was immunolocalized in the base and margins of only wounds treated with fibrin sealant supplemented with TGF-β2. A significant increase in matrix metalloproteinase-9 activity was found in fibrin sealant–treated wounds at day 7 as compared to sutured wounds. Addition of TGF-β to the fibrin sealant suppressed the up-regulation of matrix metalloproteinase-9 in these wounds. These results suggest that fibrin sealant supplemented with TGF-β may provide superior wound healing as compared to fibrin sealant alone. (WOUND REP REG 2002;10:252–258)
