C-section - VIN Flashcards
duration of pregnancy is not based on breeding date but based on when ________ occured
Ovulation
Maturation in puppies can be determined by _______ (diagnostic aid) when we don’t have ovulation timing
AUS
_______ and _______are two commonly used markers of maturity.
Renal definition
intestinal peristalsis
Progesterone drop alone is not the best predictor. T/F
True
we cannot, unfortunately, PLAN a c-section unless we have good prior ovulation timing (ORT) T/F
True
< __ or >__ are more likely to require a C-section.

How to plan a C-section in case where we donot have ovulation timing?
- Wait for signs of labor
- Whelpwise monitoring system
- Serial AUS monitoring
What findings on AUS helps you decide that the fetuses are mature?
- Clear line of demarcation between renal medulla and cortex
- Visualization of striations in the intestinal wall and peristalsis,
- Fetal HR coming down from the 200’s to the more 180’s
____ fetal heart rate means fetal DISTRESS and ___ means an emergency

While a P4 (at least done on an Immulite machine-I don’t necessarily trust the in house ones) < 2ng/ml tells you it is safe to cut, there are a signficant percentage of bitches whose progesterones DO NOT drop below 2 ng/ml . T/F
T
there are a signficant percentage of bitches whose progesterones DO NOT drop below 2 ng/ml T/F
T
temperature drop occurs BECAUSE of progesterone drop. T/F
T
how to instruct owner regarding temperature drop?
monitor bitch when at rest for 20 minutes TID starting several days prior to the first potential due date so they can see what the normal variation is (in my bitches 101 to 99) and look for a drop a full degree below the low end of the normal variation (in my bitches 98 or 97.9F).
*There is also the complication that if the owner takes the temperature inside feces the temperature read will be lower than the normal range.
ONLY planned C-section is one where good OVT is done-the rest are essentially an emergency C-section, although the extent of the emergency is determined by how much money they are spending on testing at the parturtion end. T/F
T
In cases, were we donot know OVT I schedule them for their first P4 about _____ days after breeding date. I assume they could be ± __ days from that point. Rarely are they ready that day. If I see progesterone dropping, I will start to do ultrasounds.
