Q

When do you stop advancing the needle with a caudal epidural once it is in the intercoccygeal space?

Q

What must be done differently for the distal vs proximal paravertebral nerve block?

A

For distal the spinal nerves have already split into dorsal and ventral branches so equal volume must be above and below
For proximal splits above and below transverse process so inject more volume below transverse process

What side of the the cow is this?

A

Left

31
Q

What side of the cow is this?

A

32
Q

What is the reticular groove?

A

Facilitates flow of milk from esophagus directly into omasum and abomasum, bypassing reticulum and rumen

33
Q

Label each stomach component

A
34
Q

Which stomach component is this?

A

Abomasum

35
Q

What does each circle represent if a ping is heard at each location?

A

Red - left displaced abomasum
Green - rumen gas cap
White - pneumoperitoneum

36
Q

How can you differentiate pings?

A

Location, quality of ping, succession, pass stomach tube, liptac test, ultrasound

37
Q

A

Auscult & percuss - ping, centered over 10th and 11th ribs, round ping (primarily gas)
Succus fluid splash
Rectal - not palpable

38
Q

What does each circle represent if a ping is heard at each location?

A

Red - RDA, abomasum volvulus
Blue - colonic distension
Yellow - cecal dilatation / volvulus
White - pneumoperitoneum

39
Q

What are the characteristics of a volvulus ping?

A

Centered over 10th-12th rib
Large : 9th ICS -> mid paralumbar fossa
