TPVB alone has previously been compared with GA alone .
We present a series of 28 patients who received an ultrasound guided TPVB with sedation alone at one, two, or three levels, for breast cancer surgery at a single UK centre between 2008 and 2012.
24 (86%) patients had significant comorbidities which either indicated TPVB alone, or were contributory factors in the decision making process.
10 TPVB injections were performed at two levels (T3 and T5), two at three levels (T3, T5 and T6), and the remaining 16 at just one level (six at T3, eight at T4, one at T5, and one at T6).
One had a wide local excision with TPVB performed at one level with no additional opiates required.
Whilst these are not absolute indications for TPVB with sedation rather than GA, many are relative contraindications to GA and were therefore contributory factors in the decision making process following full discussions with the patients beforehand.
