Acupuncture for neonatal abstinence syndrome in newborn infants
Bibliographic record
Abstract
BACKGROUND: Neonatal abstinence syndrome (NAS) is a drug-withdrawal syndrome, mostly occurring after antenatal exposure to opioids. A neonate may be born physically dependent on opioid medications, which causes withdrawal symptoms (such as high-pitched crying, disruptions in the sleep-wake cycle and tremors) after birth. This is diagnosed with a standardised withdrawal assessment, such as the Finnegan score. Newborns developing NAS require medical treatment and longer hospital stays after birth than neonates without this condition. Treatments for NAS include multiple multimodal treatments to ease symptoms of withdrawal, such as swaddling, 'rooming in' and breastfeeding. If the standardised assessment exceeds a certain threshold, newborns are treated pharmacologically with an orally administered opioid. However, optimal NAS management continues to be debated. Acupuncture has been proposed as a potential intervention. Acupuncture involves stimulation of specific points on the body, either through the insertion of thin metal needles or with techniques that do not penetrate the skin, such as acupressure and laser. OBJECTIVES: To assess if acupuncture (acupressure, needle, laser) reduces the treatment duration of neonatal abstinence syndrome (NAS) in newborn infants, reduces adverse events and reduces length of hospital stay. SEARCH METHODS: We used bibliographic databases (CENTRAL, PubMed, Embase) and trial registries, together with reference checking, citation searching and contact with study authors, to identify the studies that are included in the review. The latest search date was 25 August 2023. SELECTION CRITERIA: We included randomised controlled trials (RCTs) or quasi-RCTs, and cluster-randomised trials. We included infants born at full term and late preterm who were diagnosed with NAS within the first 72 hours after birth (i.e. showing significant signs as assessed using a standardised NAS assessment tool, e.g. presenting with withdrawal syndrome and Finnegan score > 8). We included studies where acupuncture (using invasive or non-invasive techniques) was compared with: 1) no intervention; 2) placebo or sham treatment; 3) any pharmacological treatment; or 4) another type of acupuncture (e.g. penetration of the skin with a needle versus acupressure). Acupuncture could be given alone or in combination with conventional medical treatment for NAS ('standard care'), as long as the latter was administered to the control group as well. DATA COLLECTION AND ANALYSIS: We used the standard methodological procedures expected by Cochrane. Our primary outcomes were duration of any pharmacological treatment for NAS, adverse events and length of hospital stay. We used GRADE to assess the certainty of evidence. MAIN RESULTS: = 0). • Length of hospital stay in days. In one study (28 infants), the median and IQR were 35 (25 to 47) days and 50 (36 to 66) days in the acupuncture and control groups, respectively. In the other study (76 infants), the mean duration of any pharmacological treatment for NAS was 25.8 days (SD 16.4) and 26 days (SD 13.3) in the acupuncture and control groups, respectively (MD -0.20, 95% CI -6.90 to 6.50; 1 study, 76 infants). • Highest score in a single standardised NAS assessment. One study (28 infants) reported median scores of 15 (IQR 13 to 18) and 16 (IQR 14 to 19) in the acupuncture and control groups, respectively; the other study (76 infants) reported that the average NAS score per scoring event was slightly lower (mean 4.95, SD 1.00) for the 'control' infants than for the infants assigned to acupuncture (mean 5.27, SD 1.04). We judged the certainty of the evidence to be very low for all these outcomes. No studies reported data on all-cause mortality, pain or long-term follow-up. AUTHORS' CONCLUSIONS: The limited available evidence is insufficient to establish the benefits and harms of acupuncture for the management of NAS in newborn infants. Both studies we included in this review assessed non-invasive acupuncture and reported no adverse effects; however, data are drawn from a very small sample. In light of current limitations, clinicians are urged to approach the use of acupuncture in newborn infants with NAS cautiously, as there is currently no evidence to support its routine application. This systematic review highlights the need for well-conducted, large randomised controlled trials to achieve an optimal information size to assess both the benefits and harms of acupuncture for NAS. In addition, comparisons of acupuncture techniques and sites should be made to assess effectiveness and feasibility.

Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
