Sterile Water Injections for Pain Relief

Before ethical standards changed, doctors used to occasionally fool patients with placebo injections of sterile saline or water. If my obstetrician had tried to give me sterile water instead of an epidural, I probably would have hit him. But apparently women are getting sterile water injections for childbirth and are telling us they work. What’s going on?

A recent study in Sweden compared sterile water injections to acupuncture for relief of labor pain. It found that sterile water produced significantly greater pain relief and relaxation. It concluded, “Women given sterile water injection experience less labor pain compared to women given acupuncture.”

I’m puzzled, because the study also says “there were no significant differences regarding requirements for additional pain relief after treatment between the 2 groups.” 85% and 90% got nitrous oxide, 40% and 47% got epidurals, and other conventional interventions were also used. It seems to me the conclusion could just as well have been “Women given sterile water injections report less labor pain than women given acupuncture, but require just as much additional pain relief.” (more…)
