Plasma expanders are used in: (A) Endotoxic shock, (B) Neurogenic shock, (C) Vasovagal shock, (D) Anaphylactic shock
Answer is A. During endotoxic shock,the amount of blood that can be delivered to the tissues get reduced due to loss of RBC's and decrease in blood volume which causes a decrease in blood pressure. Therefore,plasma expanders are used for the maintanence of blood volume in the body.They act by increasing osmotic pressure. Ref : SRB's manual of surgery 6th edition
