What is the difference between a LA laceration pack vs general pack

laceration pack:

• less instruments

• usually have olson hegar needle holders b/c no assistant

• includes sterile towels for drapes

What self-retaining retractors are commonly used in large animal?

• gelpi and weitlaner

• balfour (abdominal retractor in small animal)

What are doyen intestinal forceps used for in LA?

occlude lumen of small intestine with minimal trauma

What are the advantages and disadvantages of GI staplers in LA?

advantages:

• faster

• inert compared to suture

• reduce contamination & preserve blood supply

• use in areas of limited accessibility

disadvantages:

• $$$

• possibly leakage

• may be limited if tissue is thickened (edema)

• trained personnel

What is a TA-90?

thoracoabdominal stapler - does not cut, only double row of staples

What LA GI stapler is linear and cuts and divides at the same time making it useful for GI anastomosis?

ILA (intestinal linear stapler)

What LA GI stapler is useful on mesenteric vessels?

ligating dividing stapler

What are the different equine emasculators?

• Serra & modified white: simultaneous crush and cut

• Reimer: crush and separate cutting handle

• Sands: crush only

• newburry knife: cuts scrotum

• elastrator bands: typically done by produce on YOUNG animals

• emasculators and henderson

What is the function of lasers commonly used in equine URT surgery?

• scar the tissue to make it less flexible

• incise/excise mucosa or masses

• can get into tight space of larynx/pharynx

What are the advantages & disadvantages of lasers (vs conventional surgery) in LA?

Advantages:

• decreased bleeding, swelling, and pain

• kills bacteria as it cuts

• use through the endoscope

• precise cutting

Disadvantages:

• requires specialized training

• equipment is expensive

• can result in excessive thermal damage to surrounding tissues

What are the uses of the laser in LA surgery?

• upper airway surgeries

• uterine cysts

• skin tumors

• neurectomy

• fusing hock joints (facilitated ankylosis)

• hemostasis during laparoscopic surgery
