6 - Feline OHE & Orchiectomy Flashcards
What ligation is used in a feline orchiectomy?
Auto-ligation with pedicle tie
What general technique is used in a feline orchiectomy?
overhand tie
What instrument is used to perform a feline orchiectomy?
Halsted mosquito hemostat
What does an ovariohysterectomy mean?
Removal of the ovaries and the uterus
In an OHE, the surgeon most commonly stands on the _____ side of the patient.
right
What are the general steps to an OHE?
- Locate one of the uterine horns
- Break down suspensory ligament to exteriorize the ovary
- Clamp proper ligament to keep traction on it
- Clamp ovarian vessels with Rochester carmalts proximal to the ovary
- Ligate and cut ovarian blood vessels within ovarian pedicle
- Ligate and resect uterine body and blood vessels just above the cervix
What is the approach to beginning a feline OHE?
- Ventral midline
- Divide abdomen into 3rds from umbilicus to pubis
- Incision centered on middle 3rd of caudal abdomen
What size blade should be used for the initial incision and for what layers?
10 - skin and into the SQ
What should Metzenbaum scissors be used for when entering the abdomen?
Pushing SQ tissue off the body wall
How should the linea alba be opened?
Tent up and make a stab incision (blade facing up), extend the incision carefully
What suture should be used to ligate the ovarian pedicle?
PDS 2-0 or 3-0
What two ligatures should be used on the ovarian pedicle?
- Miller’s Knot (closest to body) in crushed area of 1st forceps
- Transfixation or encircling ligature in crushed area of 2nd forceps
Where do you cut to transect the ovarian pedicle and what is used to do this?
Cut between 2nd carmalt and the ovary;
Use Metzenbaums or scalpel blade
What should you do before you let go of the pedicle?
Hold with thumb forceps and evaluate hemostasis
After the ovary has been transected, what is done with the broad ligament?
It is torn to the uterine bifurcation
What suture is used to ligate the uterine body?
PDS 2-0 or 3-0
What ligatures are used in the uterine body?
- Miller’s knot - proximally (closest to abdomen)
- Transfixation - closest to the bifurcation
What should you do before letting go of the uterine pedicle?
Hold with thumb forceps and evaluate hemostasis
What suture should be used to close the linea alba?
PDS/Monodox (Polydiaxanone) 3-0 or 2-0
What pattern should be used to close the linea alba?
Simple continuous
Where should suturing of the linea alba begin and end?
Begin and end past the apex of the incision
How many throws should be done on each knot for linea alba closure?
6
T/F: Knots on the linea alba should not be buried.
True
What suture should be used to close the SQ?
Monocryl/monoswift (Poliglecaprone 25) 3-0 or 2-0
What pattern should be used on the SQ?
Simple continuous
How many throws should be done on each knot in the SQ?
6
T/F: You should never bury the knot in a SQ closure.
False - can bury to make the intradermal closure easier
What suture should be used to close the skin and what pattern?
Same suture as SQ;
Intradermal pattern
T/F: Knots for skin closure in an intradermal should be buried
True
