Summary

Effective postoperative pain control is an essential component of surgery. Adequate analgesia improves patient comfort and satisfaction, thereby permitting earlier mobilisation, faster recovery and less likelihood of complications.The majority of surgeons will place 10ml of local anaesthetic into the breast pocket or inject it into the breast skin following breast surgery. A more specific technique is to identify the nerves supplying the breast and put the local anaesthetic directly around them (Pec block). This nerve block has recently been described and is increasingly being used by anaesthetists for surgery under local anaesthetic or for post-operative analgesia. It has been shown to provide better and more specific pain relief in several studies.

Anaesthetists use an ultrasound machine to identify the anatomical landmarks for the nerves and they inject into the vicinity. They do not have direct vision and there is a risk of causing morbidity or the block not being effective. It is much easier for a surgeon to apply the block, as they can see the anatomical landmarks. Despite this, very few surgeons are aware of the technique.

The study group consists of patients undergoing bilateral cosmetic breast surgery at BMI Edgbaston and Priory hospitals and Spire Parkway and Southbank hospitals in Birmingham and Worcester. If a patient consents to being involved in the research, they will have one breast randomised to receiving a pec block and the contralateral (opposite) breast will receive the same amount of local anaesthetic placed in the breast pocket in a non-targeted fashion. The patients and researcher will be blinded as to the allocation. Patients will complete a verbal numeric pain score for each breast at set intervals until they are discharged.In addition, the investigators will specifically ask which breast is the most painful at each time point.

The results of the study may improve patient care.

Conditions

Interventions

OTHER

targeted chirocaine pec block

10ml 0.25% chirocaine in a specifically targeted in a nerve block

OTHER

standard chirocaine infiltration

10ml 0.25% chirocaine is infiltrated into breast pocket in a non targeted fashion
