• Provide documentation of labor

Types of fetal monitoring:

1- Internal fetal monitoring
2- External fetal monitoring

➢ Internal fetal monitoring:

Definition:
*An electrode is attached to the fetal ECG Invasive

• Internal monitoring can't be used unless the cervix dilated and the membranes are
ruptured to allow replacement of the scalp.
• The ultrasound probe (transducer) is applied to the mother's abdominal wall. It

detects movement of fetal cardiac valves or movement of blood in the fetal heart and
vessels

Technique:

• Internal monitoring can't be used unless the cervix dilated and the membranes are
ruptured to allow replacement of the scalp.

• It requires cervical dilation at least 2cm to allow replacement of the scalp.
• Presenting part is low enough to allow placement of scalp.

• High skilled practitioner should be present and use aseptic technique.
• Placement a spiral electrode into fetal presenting part usually head to assess FHR and
record uterine contraction.

➢ Advantage:

1) more accurate in displaying an FHR between 30 and 240 b/min.

➢ Disadvantages:
1) Perforation of uterus or placenta of fetal damage due to misapplication in fetal

presentation wasn’t recognized.
2) Carry the risk of infection of scalp or amnion.
3) The insertion of electrode may cause bruising on the part of fetus that electrode is
attached.

4) Insertion of electrode may be un comfortable for mother.
