Dr Sumit Das

My name is Dr Sumit Das. I am a Consultant Anaesthetist in Oxford. I have been working privately with Mr Johnson for 15 years in both Oxford and Swindon.

I normally meet with you for the first time when I visit on the day of surgery. This is where I will carry out an assessment and discuss the options for anaesthesia and pain relief. After the operation, I will visit you again to ensure all is well. I can be contacted by Mr Johnson or nursing staff if there are any concerns at any time during your hospital stay.


Anaesthesia means ‘loss of sensation’. General anaesthesia involves drugs which induce a deep sleep; Anaesthetics are used for pain relief during surgical operations so that you do not feel pain, touch, or pressure. Local anaesthesia involves injecting drugs into the skin to numb a small area. Sedation involves drugs that produce sleepiness or a light sleep but stop short of general anaesthesia. All of these techniques can be used alone or in combination depending on the specific procedure. 



Are anaesthetics safe?
Anaesthesia has advanced over the past 10 years and as a result anaesthesia is very safe. But, in common with all medical interventions, anaesthesia has an element of risk which varies according to the circumstances.

Will I get a Pre-med?
Sedative premeds are not routinely given but may be of benefit in anxious patients.


Common Concerns

1. Nausea
Nausea (feeling and being sick) after a general anaesthetic is a common fear. Because it is so unpleasant, a combination of medications and other techniques to reduce the incidence of nausea are routinely employed.

2. Post-operative pain
It is my aim to optimise pain relief while minimising the side effects of the painkillers. A variety of medications are used for minor surgery. Intermediate surgery often requires the addition of stronger pain killers which may be required as injections. Major surgery usually requires strong painkillers in a drip. Every patient feels pain in a slightly different way, and I aim to tailor your pain control to your requirements.


Air Travel Before and After Anaesthesia

Any operation carries a small risk of clots developing in the leg called deep vein thrombosis or DVT. The risk is greater with longer operations, in smokers, in women, and in patients with chronic infection. Operations on the pelvis and legs carry a higher incidence.

Air travel carries a risk of DVT due to depressurisation and inactivity. The risk is greater in economy and increases with the length of the flight. You should not fly immediately before or after an operation as each operation and each flight are accumulative. If you live abroad, you should plan to arrive a few days before the operation and do not fly immediately afterwards. 

If you are flying, please let me know at the pre-operative consultation so I can assess your risk and decide whether to give you anticoagulants. In most cases, it is recommended that patients wait until the first full week after surgery, once the first follow-up visit with the surgeon has been completed.


Herbal and alternative therapies

The actual ingredients of many novel and alternative therapies are uncertain and, in some circumstances, will interact with anaesthesia. As a result, I advise that all herbal and alternative medications are stopped at least one week prior to surgery.


Medication and allergies

As a general rule you should continue to take all your normal pills and medications (with a sip of water if required) at the normal times even on the day of surgery except in the following circumstances..

✤  you take any drugs that end with ….pril (eg ramipril, lisinopril) – avoid these on the day of surgery

✤  you take any drugs that end with …artan (eg losartan, valsartan) – avoid these on the day of surgery

✤  you take tablets to control your diabetes. All pills and tablets used to treat diabetes should be omitted on the day of surgery (if you take long-acting medication e.g. Lantus, please discuss this with me)

✤  you take warfarin. Warfarin should be stopped 5 days prior to surgery. If you take warfarin because you have a mechanical heart valve you will need specialist advice

If you are having  a facelift procedure or eyelid surgery, then your blood pressure control is extremely important, please discuss your medication with me well before the day of the operation.
