Abstract

Hypodermic needles are in widespread use, but patients are unhappy with the pain, anxiety, and difficulty of using them. To increase patient acceptance, smaller needle diameters and lower insertion forces have been shown to reduce the frequency of painful injections. Guided by these observations, fine needles and microneedles have been developed to minimize pain and have found the greatest utility for delivery of vaccines and biopharmaceuticals such as insulin. However, pain reduction must be balanced against limitations of injection depth, volume, and formulations introduced by reduced needle dimensions. In some cases, needle-free delivery methods provide useful alternatives.

  • Opting for a smaller needle size such as a 25-gauge can reduce needle insertion force and minimize patient discomfort.

    “While typical needle sizes range from 21-gauge (21G) to 23-gauge (23G), opting for a smaller needle size such as a 25-gauge (25G) can reduce needle insertion force minimizing patient discomfort (Gill and Prausnitz, 2007;Patout et al., 2015)”

    The paper’s 'Factors Affecting Pain from Needle Insertion' passage reports that smaller-diameter needles can reduce pain, and its discussion of insertion mechanics links lower insertion force with less pain (page not provided). It lists 25-gauge needles as suitable for some injections, but does not show that switching from 21–23 gauge to 25 gauge reduces insertion force or patient discomfort specifically. (LLM, conf=0.85)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
