Randomized Controlled Trial Comparative Study
Superiority of postoperative epidural over intravenous patient-controlled analgesia in orthopedic oncologic patients.
Surgery for bone malignancy is associated with intense postoperative pain. Patient-controlled epidural analgesia (PCEA) and intravenous patient-controlled analgesia (IV-PCA) are used currently for postoperative pain control. ⋯ Postoperative ropivacaine + fentanyl via PCEA reduces pain better and affords better subjective feelings than IV morphine via PCA after resection of bone malignancy carried out under combined general and epidural anesthesia.

Postinjury multiple organ failure (MOF) is a result of a dysfunctional inflammatory response to severe injury and shock. Acute lung injury is thought to promote further organ dysfunction by the systemic release of inflammatory mediators from injured lung tissue. Although clinical evidence supports this model, a clear understanding of the relationship between lung dysfunction and multiple organ failure has yet to be defined. We hypothesized that respiratory dysfunction is an early obligate event in the progression of postinjury MOF. ⋯ Postinjury respiratory dysfunction is an obligate event that precedes heart, liver, and kidney failure. The severity of other organ dysfunction is related directly to the severity of respiratory dysfunction. These data implicate lung dysfunction as central to the promotion of pathogenic inflammation and the development of postinjury MOF.
