Sedation versus General Anaesthesia

  Advances in anaesthetic drugs mean many procedures can now be undertaken under sedation. Many patients find this decision quite difficult and I thought that a blog explaining the difference would be helpful.   General anaesthesia provides loss of consciousness or awareness together with pain relief. If you have a general anaesthetic you will be… Read more »


Although anaemia is normally diagnosed and treated by doctors, I thought it would be worth writing a blog for my patients about anaemia because although the management is becoming clearer, many of my patients are confused by different information provided by different doctors approaching the problem from different directions.   First a little about the… Read more »


We are realizing that preventative medicine is as important as treatment. I have recently posted blogs on over-the-counter drugs that we might give to people without disease as well as a blog on healthy living. To complete my thoughts on preventative medicine, I wanted to post on health screening I am a great believer in… Read more »

Over the counter ‘Drugs’

When we talk about blood-borne infections we mean hepatitis and HIV where the concern is that patients carrying these viruses are asymptomatic and unaware that they are carriers. The relevance to me as an anaesthetist is protecting my staff. We practice what is called universal precautions which means effectively we treat patients as if they… Read more »

Promoting healthy living has become an industry but like vitamins and minerals which are too often 21 st -century snake oil there is a lot of fake news. So what can… Read more »


I am often asked by patients if an anaesthetic, or repeated anaesthetics, cause long-term harm. The simple answer is no. The risk of an anaesthetic is very low and if you have no other medical problems the risk of a catastrophic complication is 1 in 83,000 – about the same risk as being knocked down… Read more »

Anesthesia and Cancer

As other illnesses have become less frequent and we have become better at treating them, cancer has become the most common reason for needing general anaesthesia. Advances in radiotherapy and chemotherapy, many originating from my own hospital St Bartholomews in London, together with surgery remain the mainstay of treatment although immunotherapy and genetics offer exciting… Read more »


Every patient admitted to the hospitals in which I work is asked to complete an audit form. These are analysed and ranked by an independent company and provide valuable insight into how well we are performing. One of the commonest issues raised is the admission process and although this is not directly related to my… Read more »
