Sumario: | This prospective, randomized study aimed to evaluate the efficacy of an intraoperative pectoralis nerve II block (PECS II block) under direct vision in the reduction of fentanyl consumption during postoperative 24 h in patients undergoing robotic nipple-sparing mastectomy (RNSM) with immediate breast reconstruction (IBR) using direct-to-implant (DTI) or tissue expander (TE). Thirty patients scheduled for RNSM with IBR were randomly allocated to the PECS (n = 15) or control (n = 15) groups. The PECS II block was applied under direct vision after RNSM. The primary outcome was the cumulative dose of fentanyl consumption. The secondary outcomes were pain intensity using a numerical rating scale (NRS) at rest and acting during the postoperative 24 h. The cumulative dose of fentanyl at 24 h was significantly lower in the PECS group than in the control group (p = 0.011). Patients in the PECS group showed significantly lower NRS scores during the first postoperative 2 h compared to those in the control group in both resting and acting pain (p < 0.05). An intraoperative PECS II block under direct vision can reduce opioid consumption during the postoperative 24 h and provide effective analgesia in patients undergoing RNSM with IBR using DTI or TE. |
