Lecture 10 9/5/24 Flashcards
what should occur during the preparation for abdominal surgery?
-clip and aseptically prep the abdomen and beyond to prepare for unexpected events
-position animal so that appropriate regions are available for final prep and draping while maintaining respiration and blood flow
-review surgical checklist
What is gossypiboma?
retained gauze sponge or cloth laparotomy pad
What are the potential issues associated with a retained sponge?
-abscesses
-adhesions
-fistulas
-malignant transformations
How are retained sponges prevented/identified?
-sponge counts prior to incision and prior to closing
-radiopaque sponges
What are the characteristics of abdominal incisions?
-typically ventral, possibly flank
-may need to go around prepuce in males
-want to prep caudal half of thorax when making cranial abdominal incisions
What are the steps to exposing the linea?
-incise subcutis down to linea
-avoid excessive lateral dissection of subcutis; associated with dead space, seromas, and increased trauma
What are the steps to opening the abdomen?
-tent the fascia with forceps
-hold scalpel with sharp blade edge upward and handle parallel to abdominal wall
-make a stab incision into wall
-sweep fingers/scissors to feel for adhesions prior to extending incision
-extend incision slightly and verify no adhesions
-complete incision with scissors
How are thumb forceps used when opening the linea with a blade?
thumb forceps are used to lift rectus sheath up and provide a guide for the blade
What are the steps to removing the falciform ligament?
-transect lateral body wall attachments with scissors, cautery, or tearing
-ligate the base of the falciform ligament with absorbable suture
What are the steps to visualizing the abdomen with retractors?
-place sponges along body wall; moisten sponges where they will contact tissue (optional step)
-place retractors so they hold back abdominal musculature on each side
-ensure no organs are trapped between retractor blades and body wall
What are the four main goals of tissue excision?
-detach structure from fascia, peritoneum, or fibrous tissue
-ligate and transect blood vessels without damaging blood flow to remaining structures
-ligate and transect functional connections that will no longer be needed
-re-establish any critical functional connections
What are the steps taken in hollow organ surgery?
-isolate organ with laparotomy pads
-set aside clean instruments; do not want to use instruments that were inside the organ
-place stay sutures as needed
-close incisions with absorbable suture
-change contaminated gloves and instruments
What are the characteristics of lavage?
-used to remove contamination or warm patients
-balanced electrolyte solution warmed to body temp.
-poole suction tip used to prevent organ damage
What are the steps of abdominal wall closure?
-appose rectus sheath with continuous or interrupted pattern
-appose SQ tissues to close dead space, reduce tension on skin, and potentially improve blood supply
-close skin with external or buried sutures
