c. longer than 50cm, should have a 30deg angle, and should be 10mm in diameter
d. 35cm long, should have a 0 angle, and should be 10mm in diameter
e. longer than 50cm, should have a 30deg angle, and should be 5mm in diameter

A

c. longer than 50cm, should have a 30deg angle, and should be 10mm in diameter

17
Q

The main disadvantage of using CO2 for abdominal insufflation is:

a. cost
b. post-op discomfort
c. the formation of gas emboli
d. availability
e. b and c

A

b. post-op discomfort

CO2 not likely to cause air emboli

18
Q

Which of the following statements is FALSE?

a. The laproscopic trocar-cannula should be placed after the abdominal cavity has been insufflated.
b. Complete evaluation of the abdomen during standing laparoscopy necessitates entering both sides of the abdomen.
c. The abdomen should be maximally insufflated (>35mmHg) to avoid penetrating visera with the laparopscopic trocar-cannula.
d. IPPV is required during laparoscopy with general anesthesia
e. The use of a high-flow insufflator (>10L/min) is recommended for lapraoscopy in adult horses.

A

c. The abdomen should be maximally insufflated (>35mmHg) to avoid penetrating visera with the laparopscopic trocar-cannula.
* Must be <20 mmHg to avoid affecting cardiopulmonary function*

19
Q

The technique for performing laparoscopy for ovariectomy via ventral abdominal approach involves

a. a 1.5cm skin incision to the left of the midline for insertion og the laparoscopic trocar-cannula
b. a stab incision at the umbillicus for placement of a tear cannula to establish pneumoperitoneum
c. instrument portal placement at any location along the ventral midline
d. a 1.5cm skin incision at the umbilicus for insertion of the laparoscopic trocar-cannula
e. b and d

A

d. a 1.5cm skin incision at the umbilicus for insertion of the laparoscopic trocar-cannul

20
Q

Which of the following statements is TRUE?

a. Instrument portals are closed in three layers.
b. When making instrument portals, it is important to make the skin incision longer than the abdominal incision
c. Instrument portals should always be located approximately 5-10cm from the midline cranial to the umbillicus
d. After surgery, patients should be stall rested for 2 months
e. a and b

A

b. When making instrument portals, it is important to make the skin incision longer than the abdominal incision
