To determine whether a combination of auricular and body acupuncture is effective as an adjunct for the preprocedural anxiety and pain management in patients undergoing lithotripsy procedures.
Randomized controlled study. SETTING AND LOCATION: Lithotripsy suite located at the Yale New Haven Hospital, New Haven CT.
Adult patients who were scheduled to receive elective lithotripsy procedures.
Acupuncture group: Preprocedural auricular acupuncture intervention combined with intraprocedural electroacupuncture stimulation (n = 29); Sham control group: Preprocedural sham auricular acupuncture intervention combined with intraprocedural sham electroacupuncture stimulation (n = 27). OUTCOMES MEASUREMENT: Preprocedural anxiety, intraprocedural alfentanil consumption, visual analogue scale for pain.
Patients in the acupuncture group were less anxious preprocedure than those in the Sham Control Group 32 (29-34) versus 40 (35-45) (p = 0.029). Similarly, patients in the Acupuncture Group used a lesser amount of alfentanil than those in the sham control group (p = 0.040). The adjustable alfentanil consumption as expressed by median rate of alfentanil consumption of 1 (0.6-1.6) microg kg(-1) minute(-1) in the acupuncture group was lower than that of 1.5 (0.9-2.3) microg kg(-1) minute(-1) in the sham control group. Patients in the Acupuncture group also reported lower pain scores on admission to the recovery room (p = 0.014).
A combination of auricular and body acupuncture can be used as an adjunct treatment to decrease preprocedural anxiety and intraprocedural analgesia in patients undergoing lithotripsy.

    ABSTRACT: Background. Acupuncture has been shown to reduce preoperative anxiety in several previous randomized controlled trials (RCTs). In order to assess the preoperative anxiolytic efficacy of acupuncture therapy, this study conducted a meta-analysis of an array of appropriate studies. Methods. Four electronic databases (MEDLINE, EMBASE, CENTRAL, and CINAHL) were searched up to February 2014. In the meta-analysis data were included from RCT studies in which groups receiving preoperative acupuncture treatment were compared with control groups receiving a placebo for anxiety. Results. Fourteen publications (N = 1,034) were included. Six publications, using the State-Trait Anxiety Inventory-State (STAI-S), reported that acupuncture interventions led to greater reductions in preoperative anxiety relative to sham acupuncture (mean difference = 5.63, P < .00001, 95% CI [4.14, 7.11]). Further eight publications, employing visual analogue scales (VAS), also indicated significant differences in preoperative anxiety amelioration between acupuncture and sham acupuncture (mean difference = 19.23, P < .00001, 95% CI [16.34, 22.12]). Conclusions. Acupuncture therapy aiming at reducing preoperative anxiety has a statistically significant effect relative to placebo or nontreatment conditions. Well-designed and rigorous studies that employ large sample sizes are necessary to corroborate this finding.
