Local Measures to Limit and Control Hemorrhage
The method of pain control has already been discussed.
That is, choosing techniques and injection sites least likely
to result in hematoma formation causing airway obstruction.
Consideration may be given to alternative or adjunctive
means of pain control to limit or avoid injection
into vulnerable areas. Examples of this are sedation techniques
or even general anesthesia. Hypnosis has been used
as an adjunct in pain control in these circumstances
