Amnioinfusion for variable decelerations caused by umbilical cord compression without oligohydramnios but with the sandwich sign as an early marker of deterioration.

We report prophylactic amnioinfusion (AI) for variable decelerations in umbilical cord compression without oligohydramnios as an early sign of deterioration. We performed a transabdominal AI in cases without oligohydramnios using the ultrasonography findings of umbilical cord compression (i.e. sandwich sign [SWS]) and variable decelerations (VD) in a foetal heart rate. Thirteen cases and 21 AIs were analysed. Nine (69%) cases were of a foetal growth restriction and 4 (31%) had umbilical hyper-coiled cords. VD frequency (p < .0001), umbilical artery pulsatility index (PI) (p < .01) and ductus venous PI (0.66 vs. 0.48; p < .05) significantly decreased, and an umbilical venous (UV) flow volume (121 vs. 197 ml/min/kg; p < .05) significantly increased after AI. The umbilical artery diastolic blood flow abnormalities and UV pulsation improved. In conclusion, AI improves the umbilical cord compression even without oligohydramnios. The SWS is an important marker of deterioration to severe oligohydramnios and latent foetal damage. IMPACT STATEMENT What is already known on this subject? Antepartum variable decelerations due to umbilical cord compression are significantly associated with the deceleration in labour. In particular, foetal hypoxia leads to other adverse events such as foetal distress, hypoxic-ischemic encephalopathy, and pulmonary arterial hypertension after birth. Amnioinfusion has been shown to be effective in patients who also have oligohydramnios. What do the results of this study add? Amnioinfusion may be effective in the cases with ultrasonography findings of umbilical cord compression (i.e. sandwich sign) and in cases with variable decelerations in foetal heart rate, but without oligohydramnios. What are the implications of these findings for clinical practice and/or further research? Amnioinfusion may be helpful to prevent adverse events including oligohydramnios and anhydroamnios.
