Pentoxifylline improves survival following hemorrhagic shock.
Pentoxifylline is an agent which improves microcirculatory blood flow, but its use as therapy for shock has not been reported. We performed this study to determine if pentoxifylline improves survival following experimental hemorrhagic shock. Anesthetized Sprague-Dawley rats were studied; the animals were subjected to hemorrhage and then resuscitated using lactated Ringer's solution, with either placebo or pentoxifylline added by random selecting. Animals were then observed for 3 days. There was significantly increased survival in pentoxifylline-treated animals (p less than .05). In additional experiments, animals received more aggressive fluid resuscitation; improved survival in the pentoxifylline group was noted almost immediately and persisted through the 72-h period. This was significant at the p less than .01 level. We conclude that pentoxifylline improves survival from hemorrhagic shock in this experimental model, and has additive survival value to fluid resuscitation.
