1st Exam. Part 1. What is surgery? Flashcards
most important aspect of surgery
asepsis
treatment of disease, injuries or deformities by manual or operative methods
Surgery (from term “Chirurgiae”)
Principles or Surgery
GAO PHMA
Minimize tissue damage for better healing
gentle tissue handling
absence of pathogenic bacteria
asepsis
sources of contamination (4)
- Environment
- Materials & Supply
- Patient
- Surgical team
space left after a surgical procedure
dead space
• failure of proper closure
• accumulation of blood, exudate or transudate
obliteration of dead space
- To maintain organ function (vascularization)
- For better healing
Preservation of Adequate Blood Supply
formation of new blood vessels
Angiogenesis
Control of bleeding or hemorrhage:
Hemostasis
Examples of Hemostasis? (5)
1) Electrocautery
2) Ligation
3) Hemostatic Forceps
4) Drugs (Vitamin K., Tranexamic acid)
5) Sutures
INCREASED tension on tissue cause occlusion of blood vessels resulting in _______
Ischemia
- For better wound closure
- Wound edges have to be in proximity with
each other for better apposition/closure
Accurate Apposition of Tissues
