 Electrosurgery: 
| • | the higher degree of damping the wave form, the greater the tissue destruction and coagulation effects |  
 | • | the higher degree of rectification (less damping; i.e. square wave) the higher degree of “pure cutting” |  
 | • | mnemonic – “damping” is like sopping up the blood |  
   
  
Margins: 
| • | BCC (lesion <2cm)  -  margins of 4mm |  
   
SCC: 
| • | <2cm and low risk area  - 4mm margin |  
 | • | <1cm and high risk area - 4mm |  
   
| • | >2cm and and low risk - 6mm |  
 | • | >1cm and high risk area - 6mm |  
   
(high risk areas = ears, nose, eyelids, lips) 
  
  
Skin Grafts: 
| • | full-thickness - contracts after removal from donor site |  
 | • | split-thickness - contracts during healing |  
   
  
Prophylactic Antibiotics: 
| • | 1st generation cephalosporin 2g PO X 1 |  
 | • | OR  dicloxacillin 2g PO X 1 |  
 | • | OR  clindamycin 300mg PO X 1 |  
   
Hemostasis: 
| • | gel foam:  one can close a wound over the gel foam |
