GENERAL ANAESTHETIC

The thing about general anaesthetic that frightens everyone is the idea of waking up in the middle of an operation. The anaesthetist’s job is to prevent this from happening by monitoring the patient every step of the way.
The patient _______ a general anaesthetic in three parts. The first part is a drug	GIVE
that puts you to sleep. It works very fast. You are told to count backwards from 100, and you are usually asleep before you reach 95. From that point onwards, your brain waves are monitored by an electroencephalogram (EEG), which will warn if you are waking up. The second drug paralyses the muscles, so you need a ventilator to breathe. The percentage of oxygen in the air is controlled by the ventilator. An alarm _____ if it drops too low. The heart still works under general anaesthetic, and ______ heart rate is recorded by an electrocardiogram (ECG). The anaesthetist also monitors the percentage of haemoglobin in the blood and level of carbon dioxide. Body temperature is constantly measured, because hypothermia can occur under general anaesthetic. Despite the effects of the paralysing drug, the brain also still functions. So if you wake at the wrong time, you may be able to hear surgeons and nurses talking, and understand what is going on. You will be unable to call out, open your eyes,	SOUND YOU
or move, because your muscles will be paralysed. However, you _________any	NOT /FEEL
pain because of the _____ part of the anaesthetic-a painkiller, such as morphine. The drugs of a general anaesthetic _____ powerful and can cause hallucinations, which may explain the 'near death’ experiences described by people who are given general anaesthetic. Many ofthem say the same thing-they rose out of theirbody and _____down a corridor towards a bright light, and sometimes they have reported hearing a voice telling them to return.	THREE BE GO
