Method:

In this case, acupuncture at Ren Mai 24 was compared to the usual procedure (Lidocain spray). 36 patients with increased retching reflex (gag-reflex) were chosen and each pa-tient in the experimental randomized 3x3 cross-over design was laryngoscopied three times.

The investigational process was standardized. Objective and subjective stress indicators (heart rate, salivary cortisol, visual analog scale) were compiled and intra-individually evaluated. The following pre-treatments were randomized and blind studied:

- Acupuncture at Ren Mai 24
- Topical anaesthesia with lidocain spray
- Control group without pre-treatment Results:
- The group with acupuncture at Ren Mai 24 (p<0.005) as well as the group with topical anaesthesia with lidocain spray (p<0.01) differed significantly from the control group.

Summary:

In the present investigation of patients with a pathological increased retching reflex (gag-reflex), there was a significant reduction of the retching reflex, which was obtained by applying the acupuncture of the Ren Mai 24 (p<0.005) spot as well as the usual method (topical anaesthesia with lidocain spray) (p<0.01). The advantages of acupuncture treatment are the maintained aspiration protection, the time-restrictable effect, non-occurrence of dysaesthesia (burning, choking) and the possible application of an additional topical anaesthesia in cases of insufficient effect.
