Aspirate the joint to dry as this will alleviate evidence from small numbers and series where the pain and send material for urgent Gram stain- there were no infected cases that the severity of the ing and culture. In selected cases, crystal studies symptoms, ESR, CRP, blood count, body tempera- are appropriate. If a joint is fully aspirated the pain ture, volume of effusion or the presence of synovial relief is far better than can be achieved by analgesia, thickening are predictive of whether the fluid is bed rest or skeletal traction. A clear effusion with a negative is rare but this makes statistical analysis difficult Gram stain would allow the child to be sent home for when asking whether a sign can exclude the condi- outpatient investigation and follow-up, thus saving tion. Indeed, there are examples of children with admission and psychological trauma. The discom- small effusions and no synovial reaction who have a fort of a joint aspiration should be little different normal blood test and are afebrile and who still have to a venepuncture, especially if local anaesthetic a septic arthritis.

Wilson provides the second argument for early US-guided mechanics of alterations in joint shape and align- joint puncture. It may predict those cases liable to early problem in providing what must be a 24-hour US and stress-related degenerative disease. This carries the risk that the septic joint may deteriorate with risk if irrevocable damage to the articular cartilage.

In 2002 there were 3,846 residents in 127 accredited training programs in emergency medicine.
