| Popis: | Objective: To investigate the use of electrical impedance measurements of the pregnant cervix as an objective measure of cervical favorability (Bishop score ≥ 5). Methods: A prospective study of 86 women, investigating electrical impedance measurements of the pregnant cervix at the time of induction of labor. Transfer electrical impedance measurements were made by placing a tetrapolar pencil probe of 8 mm in diameter on the surface of the cervix. A Bishop score was determined simultaneously. Results: A mean resistivity (standard error of the mean) of 7.03 (6.01–8.04) Ωm was measured for the unfavorable group and 5.34 (4.61–6.07) Ωm for the favorable group. This was a statistically significant difference (p = 0.016). Conclusion: We highlight the ability of this safe, painless technique to differentiate the favorable from the unfavorable cervix at induction of labor. |
