Intensive care management
Admission to ITU
- Meticulous transfer of information to ensure continuity of care
- Check the haemodynamic and ventilatory parameters are acceptable
- Ensure the mediastinal drains are placed on -10cmH2O wall suction
- Clearly and concisely outline pre-operative status: (a) LV function; (b) pre-operative creatinine (c) directly relevant medical history
- operation
- post-bypass status (a) rhythm (b) pacing
- recovery plan
- Document plans in the ITU charts
