Saline infusion set
The development of saline infusion was stimulated by war experiences and was used before blood transfusions became common to replace fluids lost due to shock. Saline was first used to treat the shock of cholera by Thomas Latta in 1832. A lot of saline infusions were given subcutaneously and rectally. Gum acacia was preferable to saline for infusion.
Hot drinks: tea and coffee
Wounded soldiers were given tea and coffee to help prevent shock. Casualties in CCSs could be given up to a pint of either to ensure hydration and keep them warm before surgery.
Heated blankets, beds and ambulances were used to keep soldiers warm. Some CCSs had a resuscitation ward where soldiers too weak for surgery could be warmed with heated beds and blankets, or receive blood transfusions.
