The junctura lasso: correction of extensor tendon displacement.

Recurrent volar displacement of the extensor digitorum communis tendon (EDC) at the metacarpophalangeal joint (MCPJ) more commonly occurs post-trauma or in the rheumatoid hand. This disabling condition of the hand results in painful swelling of the MCPJ, associated with "locking" of the extensor tendon. We report a simple surgical technique used to successfully 'secure' the EDC from recurrent displacement.

Evaluation of hyperdynamic resuscitation in 60% TBSA burn-injured sheep.

It has been suggested that hyperdynamic (HD) resuscitation improves outcomes. We hypothesized that initial HD resuscitation of burn injury using fluid and inotropes would improve metabolic function as indicated by base excess. We used an anesthetized ovine model of 60% TBSA full-thickness flame burn with delayed resuscitation started at 90 min after burn and continued for 8 h.

Recombinant human growth hormone increases thyroid hormone-binding sites in recovering severely burned children.

Thyroxine (T4), Tri-iodothyronine (T3), and total serum protein levels are reduced in severely burned children. T4 and T3 are carried on serum transport proteins via thyroid hormone-binding sites (THBS). Treatment of bums with recombinant human growth hormone (rhGH) increases albumin (Alb) and prealbumin (PreAlb), which bind nearly 30% of circulating T4 and T3.

Isoflurane but not mechanical ventilation promotes extravascular fluid accumulation during crystalloid volume loading.

Background: The combination of isoflurane anesthesia and mechanical ventilation reduces urinary output and promotes redistribution of a crystalloid bolus into the extravascular space. The authors hypothesized that mechanical ventilation rather than isoflurane causes this alteration.

Methods: The fate of a 25-ml/kg, 20-min, 0.
