Of the estimated 1.06 million abortions performed in the United States in 2011, approximately 91% occurred before 13 weeks gestation. Most first trimester abortions are performed in an outpatient center with a paracervical block as the only analgesic. Paracervical block is associated with improved pain control during dilation and aspiration however, women still experience moderate to severe pain. Moderate sedation and general anesthesia, minimize pain more than a paracervical block; however increased cost, regulatory constraints, side effects, health risks, and recovery time may limit abortion access.
Pain experienced during abortion results from a complex interaction of physical innervation pathways, psychological and social factors. Pain during abortion is also influenced by additional factors such as age, pregnancy history, and self-reported pre-procedure anxiety about abortion. Adequate pain management during suction aspiration might require interventions that influence mental and emotional states as well as physical pain.
Acupuncture affects perception of painful stimuli and improves anxiety. Peripheral stimulation of acupoints mobilizes central neuropeptides involved in the pathway of anxiety and stress. In auricular acupuncture, a technique of acupuncture, needles are placed in designated acupoints on the external ear in order to alleviate health conditions, in particular pain, in other parts of the body.
In a pilot study completed at Columbia University Medical Center (CUMC) in 2016, patients seeking first trimester uterine aspiration were interested in the complementary medicine technique of auricular acupuncture as an adjunct to local anesthesia. Currently, the effectiveness of auricular acupuncture to control pain during a uterine suction aspiration is unknown.
Participants will be randomized to either auricular acupuncture with pyonex needle adhesives, placebo adhesive, or routine care using a 1:1:1 ratio. The randomization scheme will use randomly permuted blocks with a block size of 4 or 6. An investigator experienced with generating randomization sequences and not directly involved in the study will be responsible for creating the entire randomized schedule; first by defining the sequence of block sizes and second, by defining the assignments within each block. The division research office at CUMC will prepare opaque, sealed envelopes containing cards indicating whether a given patient has been randomized to receive either pyonex needles, placebo adhesive, or routine care. The allocation will remain concealed from the patient and abortion provider. The acupuncturist will open the sealed, opaque envelope immediately prior to the suction aspiration procedure and perform the intervention according to randomization assignment.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||153 participants|
|Intervention Model:||Parallel Assignment|
|Intervention Model Description:||Participants will be randomized to either 1 - auricular acupuncture with pyonex needle, 2 - placebo adhesive, or 3 - routine care using a 1:1:1 ratio. The randomization scheme will use randomly permuted blocks with a block size of 6 or 9.|
|Masking:||Triple (Participant, Care Provider, Outcomes Assessor)|
Participant: only participants in the pyonex needle and placebo adhesive group will be masked during the study. Equipment is opened behind the participant and the needles and adhesives are placed outside the view of the participant.
Care Provider: A colored hat that covers the participants ears will be placed. Outcomes Assessor: Group assignment will be masked.
|Primary Purpose:||Supportive Care|

- Visual Analog Scale for Pain (VAS Pain) Score - Acupuncture Versus Routine Care [ Time Frame: at the completion of the procedure (approximately 10 minutes later) ]Measure effectiveness of auricular acupuncture as an adjunct to ibuprofen and paracervical block for pain control during first trimester uterine aspiration by comparing the maximum pain score; as measured by VAS between women randomized to receive auricular acupuncture and routine care controls - using a 100 mm visual analog scale (VAS-P) (anchors: 0 mm = no pain, 100 mm = worst pain in my life). The VAS has no sub-scales.
- Change in Visual Analog Scale for Pain (VAS Pain) Score - Placebo Versus Routine Care [ Time Frame: prior to the procedure (baseline), at the completion of the procedure (approximately 10 minutes later) ]Measure effectiveness of placebo as an adjunct to ibuprofen and paracervical block for pain control during uterine aspiration by comparing the maximum pain score; as measured by VAS between women randomized to receive placebo adhesives and routine care controls - using a 100 mm visual analog scale (VAS-P) (anchors: 0 mm = no pain, 100 mm = worst pain in my life).
- Percentage of Patients Rated Good or Very Good on Satisfaction Survey in Overall Care - Acupuncture Versus Routine Care [ Time Frame: at the completion of the procedure (approximately 5-10 minutes) ]Using a satisfaction survey (investigator-developed, 6 questions, each question is graded on a scale of 1-5, 1 being very poor and 5 being very good) to measure effectiveness of auricular acupuncture for improving satisfaction.
