Randomized Controlled Trial
Pre-treatment with morphine does not prevent the development of remifentanil-induced hyperalgesia.
Remifentanil, an ultra short-acting opioid commonly used to supplement general anesthesia, is associated with the development of hyperalgesia that manifests clinically as an increase in postoperative analgesic requirement. This study involving adolescents undergoing scoliosis surgery evaluated whether pre-treatment with morphine prior to commencing remifentanil infusion would decrease the initial 24-hr morphine consumption and pain scores. ⋯ Pre-treatment with 150 microg x kg(-1) morphine did not decrease the initial 24-hr morphine consumption in adolescents who received remifentanil by infusion for surgical correction of idiopathic scoliosis.

Septic shock is the leading cause of multiple organ failure and mortality in intensive care units. This condition seems to be related to an overproduction of both pro- and anti-inflammatory mediators, leading to an immunological dysfunction. Therapeutic strategies aimed at reducing blood and tissue concentrations of these mediators have been developed. One of these techniques, based on extra-renal filtration, is called "coupled plasma filtration and adsorption". ⋯ Additional evidence is needed to clarify the role of this blood purification technique for the treatment of septic shock.
