Many patients have their last drink the night before an operation or examination under sedation. However, studies have long shown that a long period without liquid intake can actually be a risk factor for complications after surgery.

That is why the anaesthetists at our hospital, along with all the surgical and interventional departments, have introduced 'fasting cards'. These allow patients to remain hydrated until they are called for an operation or examination.

The benefits are many. Allowing water and clear liquids until just before surgery:

• Increases patient safety and reduces postoperative complications,
• Reduces discomfort, hunger and thirst,
• Avoids dehydration,
• Reduces the feeling of stress in patients
• Reduces insulin resistance
• May stabilise blood pressure
• May facilitate the insertion of venous lines
• Reduces post-operative nausea, vomiting and pain.
