6. The postoperative treatment and complications Flashcards
1
Q
An optimal anastomosis possesses the following properties:
A
- Tension free
- Appropriate blood supply
- Water-resistant suture line
- Tight and accurate matching layers, inward looking mucosa
- Aseptic manipulation
- No distal obstruction
2
Q
Ileus types
A
- Paralytic
- Mechanical (due to adhesions)
- Vascular
3
Q
Anastomotic leakage can cause
A
- Hypotension
- Hypovolaemia
- Hypoxia
- Microcirculatory failure
4
Q
Most common complications post-op, related to surgical site
A
- Bleeding
- Fever
- Ileus
- Anastomotic leakage
- Impaired wound healing
- Fistula (late complication of anastomotic leakage)
- Wound disruption
- Hernia formation
- Sepsis
5
Q
Most common complications post-op, not related to surgical site; respiratory
A
Ventilation, perfusion and diffusion may be affected by the surgery.
- Atelectasis (collapsed lung)
- Post-op pneumonia
- Pleural effusion
- Pulmonary embolism
- ARDS
6
Q
Most common complications post-op, not related to surgical site; other
A
Renal
• Acute renal failure
Cardiovascular • Arrhythmias • Heart failure • Acute MI • Hypertension
Vascular • Thromboemobolism • 1% of surgical patients die from PE • 50% of DVT cases are symptomatically silent • PA
7
Q
indication of haemodialyis
A
- Se[K+] >6,5 mmol/L
- Volume overload
- Se[Cre] >900 μmol/L
- Metabolic acidosis
8
Q
Malignant hyperthermia
A
Muscle disorder caused by RyR abnormalities -> Ca++ excess in muscles -> muscle rigidity, heat production and acidosis
triggered by inhalation anaesthetics or succinylcholine
