Abstract
Perinatal fetal heart monitoring involves the placement of a scalp electrode to detect the fetal
electrocardiogram. The spiral scalp electrode is one type of cardiac monitor, which requires the distal end
of the monitor to be screwed into the infant's scalp. The goal of fetal heart monitoring was to identify
"abnormal" fetal heart patterns so that timely intervention (expedited birth) might lower rates of perinatal
morbidity and mortality resulting from asphyxia. Although this involves inserting an electrode through the
dilated cervix and attaching the electrode to the scalp of the fetus, it can lead to bacterial infection caused
by invasive fetal scalp electrode monitoring. Objective: - To examine and assess the post inserted fetal
scalp electrode surface microbiologically and with high resolution scanning electron microscope - To detect
possible remnants and contamination of resterilized post inserted fetal scalp electrode with soft tissues,
microorganisms and plague using VPSEM observations. - To examine and assess the characteristics
changes of post inserted fetal scalp electroe surface using VPSEM as an alternative and prompt diagnostic
tool to study the relationship of fetal scalp electrode clinical complications (bacteria, pain etc). - To
examine and assess if VPSEM will reveal the basic structure of fetal scalp electrode and manufacturer's
biocompatibility defects of post insertion fetal scalp electrode - To test the hypothesis that the fetal scalp
electrodes used in HUSM have various degree of trauma accountability related to their manufactured
morphology or adherence to the related human anatomy.
