An epidemic of new-born photography poses: the potential dangers of passive end range positioning during induced sleep in 0-14-day-old neonates: a scoping review.

Edit Nagy, Regina Finta

PMID 33362347

WHAT IT FOUND

White noise can induce sleep and modulate pain, which may allow passive end-range neck positions in newborn photography.

Post-mortem studies link extreme extension or rotation to vertebral artery compression, but no study tested this in living babies.

Key findings

01White noise can induce sleep and modulate pain, and sleep removes protective postural responses, which may allow passive end-range neck positions during newborn photography.

02Cadaver studies found that extreme neck extension can produce bilateral vertebral artery compression.

03There is no evidence from living babies that the extreme cervical positions used in newborn photography affect brainstem blood flow.

What it does not show

The review is a scoping review, not a test of newborn photography outcomes, so it cannot show that the poses caused harm. Most evidence about extreme neck positions came from cadaver or post-mortem studies, not living neonates. The included studies were not mostly limited to the very early newborn period described in the title. The pain-modulating effect of white noise varied between people and was described as not reliable enough for clinical use. The review did not measure real-world exposure, duration or outcomes in babies.

Declared interests

The work was not funded and the authors declared no conflict of interest. One author owns the copyrights to the drawings, and another is a hobby photographer who restored the pictures.

The easy way to misread this

Do not conclude that newborn photography has been shown to cause injury or sudden infant death. The review found no evidence from living babies that extreme cervical positions cause harm, and most vertebral artery compression findings came from cadaver studies, so they describe anatomical potential, not proven harm.
