Acupuncture and Nausea

The New York Times ran a piece last week on the treatment of postoperative nausea and vomiting. As my Letter to the Editor (published in October 10th’s Science Times) points out, they completely ignored perhaps the most effective therapy for this condition.

Easing Symptoms of Nausea

To the Editor:

Re “Answers Fall Short for Nausea After Surgery

(Second Opinion, Oct. 3): As an academic integrative pediatrician often

consulted to work with children suffering from postoperative nausea and

vomiting, I read Denise Grady’s piece this morning with great interest.

I was surprised, however, to see no mention of one of the more effective,

evidence-based approaches to this troublesome and common complication.

Acupuncture and acupressure, specifically applied to the P6 (Neiguan)

point, has been demonstrated in both children and adults to be both a

safe and effective treatment for postoperative nausea and vomiting,

often with fewer side effects than conventional medication therapies.

Dr. Sunita Vohra and I presented data supporting this claim, as part of our recent AAP NCE talk on CAM research in children. Published research supports not only the safety of acupuncture and tolerability in children, but also demonstrates its efficacy for postoperative nausea and vomiting. I’ve listed a few relevant references below – it’s a rich and expanding literature. The most recent meta-analysis abstract is posted in its entirety.

Metaanalysis of acustimulation effects on postoperative nausea and vomiting in children.

OBJECTIVE: Using metaanalysis, we sought to

determine acustimulation (AS) effects on postoperative nausea and

vomiting (PONV) in children. METHODS: Metaanalyses were performed on

various acupoint AS effects including acupressure, acupuncture, laser

acupuncture, and electrical stimulation (ETS) on PONV in children.

On-line databases were searched for randomized controlled trials (RCTs)

from 1966 through May 2005. In addition, the reference lists of

reviewed papers were scanned for additional trials. The identified RCTs

were evaluated for methodological quality using the Quality Reporting

of Meta-analyses (QUOROM) guidelines, and results were pooled using the

fixed-effects model. RESULTS: Twelve RCTs were pooled for the outcomes

of 24-hour PONV including 12 trials for vomiting and two trials for

nausea. Compared with the control groups, all AS modalities reduced

vomiting (RR = 0.69, 95% CI: 0.59-0.80, P < .0001) and nausea (RR =

0.59, 95% CI: 0.46-0.76, P < .0001). Acupressure (two trials) and

acupuncture (six trials) modalities were effective in reducing vomiting

(P < .005); however, ETS (two trials) did not show significant

effects in reducing the vomiting (P = .118) in children. Compared with

the controls, medications (three trials) reduced vomiting (RR = 0.42,

95% CI: 0.22-0.7, P = .0056). There were no differences between the

medication and AS treatments (three trials) in reducing vomiting (RR =

1.25, 95% CI: 0.54-2.93, P = .6025). CONCLUSIONS: This metaanalysis

demonstrated that acupressure and acupuncture are effective treatment

modalities to reduce postoperative vomiting in children. Acupuncture

treatment is as effective as medications to reduce vomiting in

children. Acupuncture had the greatest impact on reducing vomiting when

compared with acupressure and ETS in children.
