I understand that all forms of anaesthesia and sedation carry risks, including the possibility of complications, injury, heart attack, stroke, and in rare cases, death.
I understand that surgery carries a risk of blood clots, including Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE), and that preventative measures may include early mobilisation, compression devices, and anticoagulation therapy. Thrombosed veins may also develop around intravenous (IV) sites, which usually resolve without treatment. I have informed my Consultant of any relevant history, including blood clots, cancer, varicose veins, heart or lung conditions, recurrent miscarriage, obesity, recent long-haul travel, prolonged immobility, family history of clotting disorders, personal history of thrombophilia, or use of the oral contraceptive pill or hormone therapy. I have been advised by my Consultant whether to temporarily stop taking oral contraceptive pills, hormone replacement therapy, or any other oestrogen-containing medication before surgery, and I have followed this advice.
I understand that pulmonary complications such as chest infection, partial lung collapse, or fat embolism may occur, and that these risks are higher in smokers and those with pre-existing respiratory conditions. I understand that cardiac complications are a risk with any surgery and anaesthesia, even in patients without symptoms. If I experience shortness of breath, chest pains, or unusual heartbeats after surgery, I will seek immediate medical attention.
I understand that allergic reactions or adverse responses to anaesthetic agents, medications, or surgical materials may occur, ranging from mild skin irritation to severe anaphylaxis. I have provided my Consultant with a full list of all medications, supplements, and any known drug allergies.
I understand that where repositioning is required during surgery, there is a small risk of nerve injury or pressure-related skin damage.
I have informed my Consultant if I have been diagnosed with, or have symptoms suggestive of, obstructive sleep apnoea, including heavy snoring, witnessed breathing pauses during sleep, daytime drowsiness, or use of a CPAP machine. I understand that sleep apnoea increases the risks associated with general anaesthesia and that narcotic pain medications used after surgery may further compromise breathing during sleep.
I understand that ileus (temporary disruption of normal bowel function) may occur after surgery, particularly following general anaesthesia and the use of pain medications. Symptoms may include abdominal distention, nausea, and vomiting. In rare cases, aspiration of stomach contents into the lungs may occur, which can lead to pneumonia.
