Treating a child who has lost excessive blood or is in shock from low blood pressure.
“Transfusion” in this case is referring to a 0.6% solution of saline water, or in cases where the blood loss exceeds 4 1/2% body weight (I believe he’s referring to animal cases here), a solution consisting of table sugar, salt (preferably sea salt), distilled water, and one or two drops of caustic soda or sodium bicarbonate (to balance pH). Though not exact, when the second solution is made with sea salt, it’s fairly similar to Ringer’s Solution; the solution in the book was developed by Landerer to be a quick-prep rehydration/volume-expanding liquid.
