Anaesthetic procedure

Safety | Preoperative consultation | Before surgery | After surgeryContact our specialists

An upcoming operation can sometimes cause feelings of fear, uncertainty or doubt. Many patients have an understandable, but from a professional point of view unfounded, fear of anaesthesia. We take your feelings seriously and place great importance on understandable and sensitive care by our anaesthetics team. It is very important to us that you come for your surgery feeling safe and well informed.


Today, anaesthesia has reached such a high level of safety that even critically ill patients can have long and major surgery. A surgical procedure and the anaesthesia required for it place a temporary strain on the body. But they are important for your long-term health because they can fix existing health problems and improve your quality of life.


To ensure that you are well informed and feel confident about your surgery, an anaesthesia questionnaire will be sent to you prior to your scheduled surgery along with your clinic admission information. You will also be given the opportunity to have an anaesthesia consultation.

Anaesthesia questionnaire

The anaesthesia questionnaire provides our anaesthetics team with important medical information such as previous illnesses, allergies, medications to be taken, previous surgeries, and information on any previous investigations by your family doctor or specialist. The more precisely our anaesthetics team knows the individual requirements, the better these can be taken into account in the service of safety.

Anaesthesia consultation

During the anaesthesia consultation, our anaesthesiologist specifically addresses individual questions and is able to gain a comprehensive picture of the patient’s health.

Personal contact

Because every person has their own needs and every operation has a different background, we place great importance on personal contact. The primary goal of anaesthesia is to enable surgical procedures to be performed painlessly and without stress, which is also crucial for the healing process.


To ensure a smooth surgical procedure, the following rules should be observed.

  • For safety reasons, only a small, light, low-fat meal is permitted no later than six hours before admission to the clinic.
  • On the day of the operation, clear liquids such as mineral water, tea or similar can still be drunk up to two hours before admission to the clinic.
  • Prescribed medications should be taken as scheduled on the day of surgery unless otherwise advised by our anaesthesiologist. Personal medications must be brought to the clinic.
  • If you are taking aspirin or another anticoagulant or blood-thinning medication, you will need to ask the specialist treating you whether you will need to stop taking this prior to surgery or temporarily replace it with another medication.
  • Do not smoke the night before your surgery or on the day of the operation.
  • On the day before surgery, alcohol consumption should be kept to an absolute minimum. During the night before your surgery and on the day of the operation itself, do not drink any alcohol.

If there is any change in your state of health, especially symptoms of influenza, inform the anaesthesiologist or the specialist treating you as soon as possible.

Immediately before the operation, take off any glasses, contact lenses or removable dentures as well as watches and jewellery. Do not use make-up or any greasy creams on the day of surgery.

After surgery

After surgery, you will be transferred to the recovery room for stabilisation. As well as the nursing staff and anaesthesiologist, our team will take care of you around the clock. As soon as your condition permits, you will be transferred to your room or discharged home if it was an outpatient procedure. It is important to note that after anaesthesia, you are not allowed to drive for 24 hours. Even if you are on foot, you should have someone with you to accompany you home. 


Our anaesthesiologists in the Joint Practice for Anaesthesiology at the Pyramid Clinic do their utmost to provide you with competent and comprehensive care. The team consists of experienced specialists. They are on duty around the clock and exclusively for our clinic. On our website you can get to know the individual specialists and learn more about their qualifications and experience.

If you would like a specific anaesthesiologist for your procedure, you can indicate this on the anaesthesia questionnaire. As a patient with supplementary insurance, you can freely choose not only your surgeon, but also your anaesthesiologist.
