Background and Aims:

Pectoral nerve (Pecs) block is a recently introduced technique for postoperative analgesia in breast surgery. However, there are few studies reporting patient-reported effectiveness of this technique. Thus, we conducted a study to evaluate the effectiveness of Pecs block for postoperative analgesia. 

Methods:

We retrospectively reviewed the records of 50 patients who underwent breast surgery under PECS block combined with general anesthesia (PB+ group), and other 41 patients with general anesthesia alone (PB- group). Pecs block was performed with single-injection of 30 ml of 0.375% ropivacaine. Primary end-point was Verbal Rating Scale of pain (VRS: 1; none, 2; mild, 3; moderate, 4; severe) at postoperative 1 and 24 hours. Secondary end-point was the interval between the end of the operation and the first rescue analgesia.

Results:

The majority of patients in both groups showed mild or no pain at postoperative 1 hour (Figure 1). The median value of VRS at 1 hour in PB+ group was 1, which was the same as in PB- group (Mann-Whitney U test, P = 0.19). The effect was similar at 24 hours (P = 0.47) (Table 1). The median interval to the first rescue analgesia in PB+ group was 16 hours (Figure 2), which was 1 hour shorter than PB- group, but the difference was not statistically significant (Mann- Whitney U test, P = 0.63). 


Conclusions:

Pecs block does not reduce immediate postoperative pain measured by VRS in breast surgery.
