Instead, he eased the uterus out of her body and inserted the fetoscope
, and then, through another slit, surgical tools.
Following this, an operating fetoscope
(telescope) of 2mm diameter is inserted into the uterine cavity under ultrasound guidance.
Applications of thinner surgical instruments including both trochar and fetoscope
were shown to have lower obstetrical complications.
Subsequently, the fetoscope
was introduced to listen to the fetal heart rate intermittently, sometimes weeks or months apart.
The specific obstetrical examination included: a- Abdominal examination to assess the condition and presentation of fetus, and b- Digital vaginal examination to record the bishop score of cervix, c-Partogram was maintained for all patients, and d- Fetal condition was monitored by intermittent auscultation by pinnard fetoscope
after every contraction in second stage and intermittent cardiotocography.
Fetal heart rate was assessed with a fetoscope
, although there was an ultrasound in the main labor and delivery room that could be used for more extensive fetal assessments.
Non-electronic auscultation, such as the application of a Pinard's fetoscope
to the maternal abdomen for periods of up to one minute or more, allows practitioners to hear the sounds associated with the opening and closing of the ventricular valves in the fetal heart, via bone conduction, with each fetal cardiac cycle.
is used to guide the radiofrequency ablation probe.
A 1999 American College of Obstetricians and Gynecologists (ACOG) practice bulletin states that labor may be induced for logistic reasons such as psychosocial factors and distance from hospital, as long as 1 of these 4 criteria is met: (1) fetal heart tones have been documented for 20 weeks by nonelectronic fetoscope
or for 30 weeks by Doppler; (2) it has been 36 weeks since a positive serum or urine human chorionic gonadotropin pregnancy test was performed; (3) ultrasound measurement of crown-rump length, obtained at 6 to 12 weeks, supports a gestational age of at least 39 weeks; (4) ultrasound obtained at 13 to 20 weeks confirms the gestational age of at least 39 weeks determined by clinical history and physical examination.
This included a blood pressure machine, stethoscope, fetoscope
, two pairs of disposable gloves, one safe delivery kit, a thermometer, scissors, disposable syringes and a flashlight, which was needed for night calls.
By actually palpating a pregnant belly, listening for heart tones with a fetoscope
, and feeling a cervix, our workshop participants learn about fetal positioning, pelvimetry, dilation, and station in a way that engages them more thoroughly than if these things were simply discussed.
The midwife used the fetoscope
"four or five times" to listen to the baby's heartbeat and also used the "Doppler.
