ABSTRACT
PURPOSE: To evaluate the influence of shorter- and longer-acting intra-articular anaesthetics on post-arthrographic pain. MATERIALS AND METHODS: 154 consecutive patients investigated by MR or CT arthrographies were randomly assigned to one of the following groups: 1--intra-articular contrast injection only; 2--lidocain 1% adjunction; or 3--bupivacain 0.25% adjunction. Pain was assessed before injection, at 15 min, 4 h, 1 day and 1 week after injection by visual analogue scale (VAS). RESULTS: At 15 min, early mean pain score increased by 0.96, 0.24 and 0 in groups 1, 2 and 3, respectively. Differences between groups 1 & 3 and 1 & 2 were statistically significant (p=0.003 and 0.03, respectively), but not between groups 2 & 3 (p=0.54). Delayed mean pain score increase was maximal at 4 h, reaching 1.60, 1.22 and 0.29 in groups 1, 2 and 3, respectively. Differences between groups 1 & 2 and 2 & 3 were statistically significant (p=0.002 and 0.02, respectively), but not between groups 1 & 2 (p=0.46). At 24 h and 1 week, the interaction of local anaesthetics with increase in pain score was no longer significant. Results were independent of age, gender and baseline VAS. CONCLUSION: Intra-articular anaesthesia may significantly reduce post-arthrographic pain. Bupivacain seems to be more effective than lidocain to reduce both early and delayed pain.

Patients with complicated diverticulitis rarely present with extraperitoneal manifestations but the manifestation of subcutaneous emphysema appears even more seldom. We present the case of a patient with a history of diabetes and immunosuppression, who was admitted with sepsis in association with cellulitis and subcutaneous emphysema of the left groin. The absence of peritonism due to corticosteroid treatment, a history of a recent fall with an ilio- and ischio-pubic fracture and subcutaneous emphysema led to a delay in the diagnosis. The final diagnosis was a perforated diverticulitis in a patent inguinal canal, which was only revealed after surgery. The various complications of diverticulitis, including extraperitoneal manifestations, and associated microorganisms implicated in cellulitis and subcutaneous emphysema are briefly reviewed.
