What this trial studies

This is a multi-center, randomized, blinded, controlled trial comparing thumbtack needle (a shallow intradermal, long-retention needle) to a sham thumbtack needle for pregnant women with PUQE scores ≥6 between 6 and 12 weeks' gestation. Participants will receive the assigned intervention at specified acupoints and be followed for changes in PUQE score, safety, tolerability, and quality-of-life measures. The thumbtack needle is intended to deliver continuous low-level stimulation with fewer clinic visits than traditional millineedle acupuncture. The trial enrolls a large sample across three hospitals in Hubei, China with predefined inclusion and exclusion criteria and routine adverse-event monitoring.

Who should consider this trial

Good fit: Pregnant women aged 20–45, 6–12 weeks gestation, with a confirmed intrauterine pregnancy, PUQE score ≥6, and less than 10% pre-pregnancy weight loss are ideal candidates.

Not a fit: Women with mild symptoms (PUQE <6), significant weight loss or dehydration (>10% weight loss or clinical signs of hypovolemia), or who are outside the 6–12 week gestational window are unlikely to benefit or are excluded.

Why it matters

Potential benefit: If successful, the intervention could reduce nausea and vomiting severity and improve quality of life while offering a low-cost, low-drug option for early pregnancy.

How similar studies have performed: Traditional acupuncture with millineedles has shown effectiveness for NVP, but thumbtack needle is a less-studied intradermal variant and lacks large randomized trial data.

Inclusion Criteria:

* The mother\&#39;s age is 20 \~ 45 years old, the gestational age is 6 \~ 12 weeks, and the ultrasound confirms that it is an intrauterine single or multiple pregnancy, and the weight loss is less than 10% compared with before pregnancy.
* Women diagnosed with moderate to severe NVP in the first trimester: the severity of NVP was determined by the PUQE score (see Table 1), and the PUQE score ranged from 3 \~ 15, \< 6 was mild NVP, 6 \~ 12 was moderate NVP, and ≥13 was severe NVP. PUQE score ≥ 6 may be included in this study.
