Abstract

Aim

The aim of this study was to determine the effects of vacuum extractor assisted delivery on fetal oxygenation and acid-base balance.

Methods

Sixty-one women were enrolled in the present study. The subjects were divided into two groups. Group A, consisting of 39 women, had normal vaginal deliveries. Group B, consisting of 22 women, underwent a vacuum extractor assisted vaginal delivery. Fetal arterial oxygen saturation (SpO₂) monitoring was used in all women after full cervical dilatation. After delivery, umbilical artery pH, pCO₂, pO₂ and base deficit (BDecf) levels were determined in all neonates.

Results

The mean FSpO₂ value in Group A was 51.53±5.87% and in Group B 48.03±6.39% (p<0.03). The mean cord pH value in fetuses of Group A was 7.26±0.05, and in Group B 7.17±0.09. There was also a significant difference between the two groups with regards to mean pO₂, pCO₂ and BDecf values.

Conclusions

Vacuum assisted vaginal delivery was associated with lower fetal arterial oxygen saturation levels as well as lower cord blood pH values compared to those seen after unassisted vaginal delivery. Although decreased, however, the above parameters remained within normal ranges.
