Acta Anaesthesiol Scand. 1995 Apr;39(3):323-6. Prophylactic oral ibuprofen or ibuprofen-codeine versus placebo for postoperative pain after primary hip arthroplasty. Dahl V, Raeder JC, Drøsdal S, Wathne O, Brynildsrud J. The postoperative analgesic effect of ibuprofen was compared with a combination of ibuprofen and codeine versus placebo. The study was prospective, randomized, double blind with 123 consecutive hip arthroplasty operations. All the patients received oral diazepam as premedication and spinal anaesthesia with bupivacaine 5 mg/ml 3-4 ml. Postoperatively, when the spinal anaesthesia started to wear off, the patients were randomly assigned to one of three groups; the ibuprofen group (n = 48) received 800 mg of ibuprofen orally. The ibuprofen/codeine group (IC, n = 48) received 800 mg of ibuprofen combined with 60 mg of codeine. The placebo group (P, n = 25), received oral placebo medication. The patients were observed for the need of additional opioid (e.g. ketobemidone), pain score (verbal and VAS), bleeding and side effects for five hours. The patients in the placebo group (P) had significantly higher pain scores (P < 0.05) compared with the two other groups after 2 and 4 hours, with no significant differences after 1, 3 and 5 hours. The P group also received 45% more opioids (P < 0.001) compared with the two other groups during the same period. No significant differences in bleeding or side-effects were observed between the groups. There were no significant differences between the ibuprofen group and the ibuprofen/codeine group. We conclude that a prophylactic dose of 800 mg ibuprofen orally has an opioid sparing effect with a tendency of less pain experience during the first hours after hip arthroplasty.
NSAIDs og glukokortikoider til smertebehandling av ortopedkirurgiske pasienter PRO! Johan Ræder Anestesiavd. / UiO Oslo Universitets Sykehus, Avd. Ullevål, Oslo mail: johan.rader@medisin.uio.no
NSAIDs og ortopedisk kirurgi? Hvorfor kan vi ikke bare droppe NSAIDs til disse pasientene? 1. Ortopediske pasienter har mye postoperativ smerte 1. Inadekvat smertelindring har uheldige konsekvenser - Subjektivt ubehag - Redusert opptrening, forsinket recovery - Mer kroniske smerter 3. Forbud mot NSAID fører til økt bruk av opioider - Opioide bivirkninger
Opioid problemer Toleranseutvikling Hyperalgesi utvikling Bivirkninger Kvalme, obstipasjon, avhengighet, sedasjon, kløe, søvnvansker Respirasjonsdepresjon Individuelle variasjoner i reseptor (genetisk) Variabel enteral absorbsjon Mindre effektive ved bevegelsesindusert smerte Immundepresjon (infeksjon? cancer?) men... Tar all smerte hvis bare dosen er høy nok Bivirkningsterskel følger toleranse (unntak: obstipasjon) Relativt rimelige
22 studier, 2 307 pasienter: Signifikant reduksjon med NSAID vs placebo: -Kvalme: 12% -Oppkast: 32% -Sedasjon: 29%
Opioid problemer Case 1: - Hofteprotese pasient som ligger utover ettermiddagen, dag 2 på PO: smerter, opiod, kvalm, trett Ikke postklar - Ketorolac iv: mindre smerte, redusert opioid, postklar Case 2: - Ung (12 år) rotasjonsosteaotomi, som ligger utover ettermiddagen, dag 2 på PO: smerter, opiod, kvalm, trett Ikke postklar - Ketorolac iv: mindre smerte, redusert opioid, postklar Case 3: - Pasient med kneprotese på post; mye vondt, paracetamol + opioid respirasjonsstans på post - Videre behandling m/paracet+ NSAID

Non-steroidal anti-inflammatory drugs, cyclooxygenase-2 and the bone healing process. Vuolteenaho K, Moilanen T, Moilanen E. Basic Clin Pharmacol Toxicol. 2008 Jan;102(1):10-4. -Results of fracture healing studies in animals treated with NSAIDs or in mice lacking COX-2 gene show that inhibition or deficiency of COX-2 impairs the bone healing process. -The limited clinical data also support the assumption that inhibition of COX-2 by non-selective or COX-2-selective NSAIDs delays fracture healing. -However, the clinical significance of the effect in various patient groups needs to be carefully assessed and further investigations are needed to characterize the patients at the highest risk for NSAID-induced delayed fracture healing and its complications. - In the meantime, use of NSAIDs in fracture patients should be cautious, keeping in mind the benefits of pain relief and inhibition of ectopic bone formation on one hand, and the risks of non-union and retarded union on the other hand.

Schweiz Med Wochenschr. 1993 Nov 27;123(47):2228-34. Links Fluor in the treatment of osteoporosis. An overview of thirty years clinical research. Dequeker J, Declerck K. Department of Rheumatology and Arthritis, K. U. Leuven, U. Z. Pellenberg, Belgium. t has long been known that fluoride "hardens" mineralized tissues. Fluoride ingestion through drinking water in areas naturally rich in fluoride leads to osteosclerosis, known as endemic fluorosis. The first suggestion that fluoride be used in the treatment of osteoporosis was made in 1964. However, despite 30 years of research, the treatment remains controversial. Fluoride has a dual effect on osteoblasts. On the one hand, it increases the birthrate of osteoblasts at tissue level by a mitogenic effect on precursors of osteoblasts, while on the other hand it has a toxic effect on the individual cell with mineralization impairment and reduced apposition rate resembling osteomalacia. Fluoride has a positive effect on axial bone density, but the axial bone gain is not matched by similar changes in cortical bone. Furthermore, approximately one third of patients are non-responders. The effect of the addition of fluoride to the drinking water on fracture rate is not clear. It probably only has a small relative impact on total hip fracture rates. In two controlled fluoride therapy studies the incidence of vertebral fractures decreased, while in two other studies it increased. Experience teaches that denser bones are not necessarily better bones. The major side effects of fluor therapy are skeletal fluorosis, gastrointestinal intolerance, and painful lower extremity syndrome. Fluoride is the single most effective agent for increasing axial bone volume in the osteoporotic skeleton; however, its therapeutic window is narrow. The best candidates for fluoride therapy are patients with axial osteoporosis but with good peripheral bone density. They should have a good renal function and vitamin D status.(abstract TRUNCATED AT 250 WORDS)
