ClearSleep™, the exclusive anaesthesia technique

Highly precise and meticulously performed surgery requires anaesthesia techniques of the highest calibre. Our surgeons felt that traditional general anaesthesia did not meet our patients’ needs effectively. Years of research and continued ways to find more efficient ways of enhancing patient outcomes has led to the development of the ClearSleep™ technique. The ClearSleep™ technique is exclusive to Centre for Surgery. Surgeons at Centre for Surgery now perform all their procedures as a day case thanks to ClearSleep™.  Even the procedure of abdominoplasty (tummy tuck), which traditionally requires a two to three night inpatient stay, is done as a day case at Centre for Surgery. The ClearSleep™ technique is a revolutionary step forward from traditional general anaesthesia which is the default method currently practised in the majority of operating theatres worldwide.

The goals of an anaesthetic technique specific for cosmetic surgery must achieve the following three aims:

  • Reduce or eliminate the pain associated with injection of local anaesthetic
  • Reduce or eliminate patient apprehension
  • Reduce or eliminate recall of the procedure

With ClearSleep™ anaesthesia, sophisticated microprocessor-controlled delivery systems carefully control the amount of anaesthesia delivered to the patient. This is known as a target-controlled infusion (TCI) and represents an evolution in drug delivery techniques. The correct amount of drugs are also carefully determined with the use of a depth of anaesthesia monitor. This monitoring technology is known as the bispectral index (BIS). This means that precise doses of anaesthetic medication are delivered in the safest possible way. A key aspect of the technique is the injection of local anaesthesia whilst you sleepy or asleep at the beginning of the procedure before the actual surgery begins. With the blocking of noxious stimuli to the brain, the release of the body’s stress hormones is minimised. This means you will wake up with very little if anything in the way of discomfort. A recent survey assessing postoperative pain in 150 of our former patients resulted in average pain scores of 2 out of 10. This compares with scores of 8 out of 10 for patients treated with general anaesthesia. Traditional general anaesthesia can potentially result in too much medication being delivered meaning that the patient is at risk of respiratory and cardiovascular complications.

Principles of ClearSleep™

  • Preservation of airway reflexes
  • Preservation of spontaneous breathing
  • Preservation of cardiovascular function

What does ClearSleep™ mean for you?

  • Being unable to see, hear, feel or remember any part of the procedure is a key goal of any anaesthetic technique. ClearSleep™ achieves all these aims and all without the attendant risks of general anaesthesia. At times you may be sleepy rather than asleep but you should be comfortable and relaxed.
  • Fast onset and fast offset with rapid clear headed emergence from anaesthesia
  • You breathe on your own without the aid of artificial breathing machines
  • You wake up with a heightened sense of well-being due to the euphoric effects of the medications
  • Minimal risk of postoperative nausea and vomiting, dizziness and drowsiness
  • Being able to have your surgery and go home on the same day

The total elimination of many traditional tools of general anaesthesia means the following:

  • No muscle relaxants eliminates the risk of anaesthetic awareness – a terrifying and completely avoidable anaesthetic complication.
  • No breathing tubes eliminates the risks of a sore throat and damage to teeth
  • No artificial ventilation eliminates the risk of lung injury

What does ClearSleep™ mean to our surgeons and anaesthetists?


The delivery of an anaesthetic technique like ClearSleep™ personalised to your physiological requirements can be summed up in one short sentence by all our surgeons and anaesthetists.



ClearSleep™ is totally environmentally friendly. No toxic anaesthetic gases are used which is much safer for preserving our natural environment.
