How are surgical complucations classified
Timing
Anatomical
Severity
Examples of immediate complications in surgery
Bleeding
Nerve injury
Perforated viscus
What are early surgical complications (when) and what
<30 days post
Sepsis or wound dehiscence
Anaemia
Shock
Pain
Neuropraxia (will recover)
Late complications of surgery
After 30 days
Stenosis
Adhesions
Fistulae
Weakness/loss of funciton
What are local surgical complications
Nerve palsy/paralysis
Wouna dehiscence
infection
Haemotoma
What are systemic complications of surgery
Resp compromise

Classifications of surgical complications
I-V
I - no treatment but deciation
V - death
What is grade II surgical complication defined as
Pharmacological treatment needed
What is grade III surgical complication defined as
Surgical/endoscopic/radiological intervention
eg haematoma, perforation, bleed
What is grade IV surgical intervention
Life threatening complication eg multi organ failure or CVS instability
What do when unsure of complication
Revise steps of procedure so far
Double check anatomical landmarks
Verbalise thought process to assistants/colleagues
Ask for help
How to manage a surgical bleed
Pressure
Washout - saline
Fix source of bleed
Transfusion
Prophylactic antibiotics
Check haemostasis once bleed controlled
Small vs large vessel bleed management
Small - cautery
Larger - ligate vs repair
If can’t control a bleed from a vessel
Get help
Pack
Stabilise patient + leave 24 -48 hours before 2nd look
Managing a perforation in surgery
Suction/wash to clean leakage, assess damage
Repair depends on location
Antibiotic prophtlaxis
What do with pharynx/cervical oesophagus perforation
- most left to heal, rest with NGT
How to manage a small vs large thoracic oesophagus
Small - endoscopic glue
Large - endoscopic stent or surgical repair
How to manage bowel perforation
Small - endoscopal mucosal clipping
Large - open surgery
Ureter vs bladder perforation repair
ureter stent or repair
Bladder - surgical repair
What consider post perforation
Bowel - feeding enteral vs parenteral - need to rest area
Antibiotic prophylaxis - if faecal contents into abdomen
