Inhalation sedation for dental procedures

Inhalation sedation is a light form of sedation. It is a mixture of nitrous oxide and oxygen breathed through a nosepiece. This helps the child to feel relaxed and accept treatment. Inhalation sedation is also known as ‘happy air’. It is not general anaesthesia. This page from Great Ormond Street Hospital (GOSH) explains about inhalation sedation and what to expect when your child has a dental procedure that requires it.

Cardiac anaesthetic

The anaesthetic team consists of a consultant (or specialist) anaesthetist, sometimes assisted by a junior anaesthetist, and an anaesthetic assistant, usually a nurse. An anaesthetist is a doctor who makes your child go to sleep and stay pain-free during an operation. They will stay with your child for the whole operation.

Cerebral angiography

Cerebral angiography is a test that is carried out to study the blood vessels in the brain and neck. This page from Great Ormond Street Hospital (GOSH) explains about the cerebral angiography procedure and what to expect when your child comes to GOSH to have one.
