Background & Aim: The Non Stress Test (NST) is a main assessment tool for fetal wellbeing however, it has a high rate of false-positive results. External stimulation with halogen light has been recommended to aid in provoking fetal response, decreasing false-positive results and promoting the test. This study aimed to assess the effect of halogen light stimulation on nonreactive pattern of NST.

Methods & Materials: From 850 women who underwent NSTs, 50 women with singleton and cephalic fetuses who had nonreactive NSTs were allocated to receive halogen light stimulation through a halogen light source of 1,000,000 candle power. The light was applied to the lower abdomen above symphysis pubis over fetal head for 10 seconds. Results were compared to BPP scores as a backup test. We used mean± SD, chi-square Test and Fisher&aposs Exact Test. The >α0.05 was considered as significant level.

Results: Following stimulation, 68% of nonreactive results changed to reactive patterns. In half of the cases, first acceleration occurred in less than two minutes. Almost 90% of fetuses had reactive pattern within nine minutes.

Conclusion: Halogen light stimulation decreased the incidence of non reactive tests and testing time. Halogen light stimulation is safe and efficient in fetal well being assessment.
