Reflex sympathetic dystrophy of the upper extremity--a 5.5-year follow-up. Part I. Impairments and perceived disability.
The aim of this retrospective and long-term follow-up study was to identify impairments resulting from reflex sympathetic dystrophy (RSD) of the upper extremity and to analyze the relationship between impairment and disability in RSD patients. The study group consisted of a referred sample of 65 RSD patients, with clinical signs in the upper extremity. RSD developed after fractures of the wrist or hand in 29 patients or after a carpal tunnel release in 9 patients. ⋯ According to the AMA-guides, the impairments did not lead to disabilities. Significant correlations were found between VAS-ADL and VAS-pain in the last week prior to evaluation and full fist grip-strength. Pain seems to be the most disabling effect.

Reflex sympathetic dystrophy of the upper extremity--a 5.5-year follow-up. Part II. Social life events, general health and changes in occupation.
The aim of this retrospective long-term follow-up study was to describe the psychosocial aspects, such as social life events (SLE), around the causative event of reflex sympathetic dystrophy (RSD) and the psychological history of 65 patients, 3-9 years after RSD of the upper extremity. General health and long-term changes in occupation were assessed by means of a general health questionnaire (RAND-36) and a structured interview, respectively. SLE, with a life-change unit rate more than 35, was present in 32 patients. ⋯ The pain scores of the RAND-36 among RSD patients differed significantly from those of the control group. 17 patients changed occupation after RSD. Nearly 30% of the patients had to stop work for more than one year. The results show a high coincidence between RSD and associated psychosocial disorders and this may play a role in intensifying and prolonging the symptomatology of RSD.

We performed a prospective study to determine the effect of postoperative collection and reinfusion of unwashed, filtered, salvaged blood alone and in combination with preoperative predeposited blood on the transfusion requirements of 375 patients treated with a total hip or total knee replacement. 208 patients were managed with postoperative blood salvage with use of the CBC ConstaVac autotransfusion system and closed suction drainage. Another 50 patients predeposited 1-4 units of autologous blood, before the operation, in addition to postoperative blood salvage. ⋯ Postoperative reinfusion of salvaged blood decreased the need for homologous transfusion after hip and knee arthroplasty (mean 2.7 units) compared to controls (mean 4.2 units). The combination of postoperative reinfusion of salvaged blood and predeposited autologous blood was associated with the lowest requirements for homologous blood transfusions (mean 1.7 units).
