Should a patient complain that the injection is painful inject very
discreetly or better check the injection there, move the point of the
needle and again try slowly. If the cold injection causes pain try at
another point. Put in a drop or two and should the patient still
complain discontinue and put on a spica or truss for a few days.
Observe the reaction and then if it is not severe inject again.
Remember that several injections may be made upon a patient but
hyperinjection, that is the injection of too much, will cause no
little distress and that it is impossible to remove all the paraffin
mixture or the vaseline without an open operation, if they are not
absorbed.
Needle punctures should be sealed with collodion. No other dressings
are required.
Begin codeine early and use freely when a painful reaction develops.
