What if plasma exchange is not available as treatment for TTP


Q: You just diagnosed a patient with thrombotic thrombocytopenic purpura (TTP) but you were informed by the nursing supervisor that plasma exchange with fresh frozen plasma is not available in hospital due to technical reason and it will take time before patient can be transferred to a facility where the said services are available. What would be your alternate plan to bridge that time?

A; High-dose plasma infusion with rate of 25-30 mL/kg per day. When immediate plasma exchange with fresh frozen plasma is not available, simple plasma infusion can be performed until transfer to a higher care facility is available. There is always a substanial risk of fluid overload with such high plasma infusion and you have to weigh risks and benefits of the clinical decision or to watch patient closely while plasma is infusing.
