Sažetak
AIM: This study was performed in order to assess if placental implantation site has influence on transabdominal electromyographic (EMG) assessment of the uterine electrical activity in mid trimester of pregnancy. METHODS: In this prospective study 156 unselected, nulliparous asymptomatic women with singleton pregnancy underwent transabdominal uterine EMG. Uterine electrical activity was recorded using bipolar electrodes placed on the abdominal surface for 20 minutes. Regarding the placental implantation site and presence of action potentials (AP) pregnant women were divided into two groups: anterior placenta group (APG) and posterior placenta group (PPG). Outcome measures were difference between median frequency (MF) and median amplitude (MA) of AP between the two groups. RESULTS: Action potentials were detected in 42 women - APG 25/42 versus PPG 17/42. The analyzed parameters: MF (p =0.227, Fisher exact test) and MA (p =0.679, Fisher exact test) did not show any statistical significant difference between the two groups. CONCLUSION: Background uterine EMG activity measured from the abdominal surface in mid trimester of pregnancy does not depend on placental implantation site. KEY WORDS: transabdominal electromyography (EMG), placenta, implantation site, uterine electrical activity, action potentials
