The patient observer: sterile water injections for labor pain.

Several studies have reported a good pain relief effect from sterile water injections, especially for low back pain, during labor. The aim of this paper was to illustrate the use of the method in a clinical childbirth situation by means of a descriptive case report. The woman in the report described that the method provided a powerful pain relief effect, measured by a visual analog scale, and that her experience was highly positive.
