Table 4 Postoperative pain intensity at rest (VAS score at rest)

From: Ultrasound-guided transversus thoracic muscle plane-pectoral nerve block for postoperative analgesia after modified radical mastectomy: a comparison with the thoracic paravertebral nerve block

  TTP-PECS group TPVB group P value
Postoperative 2 h 1.25 ± 0.71 1.32 ± 0.68 0.66
Postoperative 6 h 1.70 ± 0.71 1.78 ± 0.68 0.62
Postoperative 12 h 2.11 ± 0.69* 2.60 ± 0.50 0.00
Postoperative 24 h 2.21 ± 0.48 2.29 ± 0.45 0.45
  1. VAS scores at rest of all the patients were lower than 3, suggesting none of the patients suffered severe pain. There were no significant differences in VAS scores at rest between the two groups at 2 h, 6 h, and 24 h postoperatively. At 12 h postoperatively, the VAS scores at rest were lower in the TTP-PECS group compared with the TPVB group. Data are expressed as mean ± SD (39 in the TTP-PECS group and 38 in the TPVB group)
  2. *P < 0.05, versus the TPVB group
