Postnatal water immersion after perinatal death: a clinical study of appearance preservation and autopsy validity.
Observational study in Archives of gynecology and obstetrics, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivePerinatal loss is an emotionally devastating event for affected families. In some clinical settings, postnatal immersion of perinatally deceased infants in water is used to preserve the infant's external appearance and facilitate parental farewell. The objective of this study was to evaluate possible effects of this practice on autopsy findings and diagnostic validity.
methodsIn this observational study, 28 infants after perinatal death with available autopsy data were analyzed. Fourteen infants were immersed in cold water after birth (water group) and fourteen infants were stored without water immersion (control group). Macroscopic appearance, degree of maceration, and microscopic findings in liver and lung tissue were assessed during autopsy. Descriptive analyses explored associations between maceration degree and the intervals between fetal death, birth, and autopsy.
resultsInfants immersed in water showed improved preservation of external appearance, including skin color, texture, and body posture. No macroscopic differences attributable to water immersion were observed during autopsy. No microscopic differences in the two investigated internal organs were observed between the water and control groups. Maceration grade assessed at autopsy showed no consistent increase with longer birth-autopsy intervals, whereas higher grades were more frequently observed with longer estimated intervals between fetal death and birth in both groups.
conclusionIn this observational cohort, postnatal immersion in water after perinatal death was not associated with impaired autopsy findings. Maceration was primarily related to the intrauterine interval between fetal death and delivery rather than postnatal storage conditions. These findings suggest that the water method may offer a simple approach to support parental farewell while maintaining the diagnostic reliability of perinatal autopsy.
