To determine whether in post-mastectomy breast cancer patients, PEC II block plus single-dose intravenous analgesia is more effective than single-dose intravenous analgesia in treating postoperative pain. Methods: An observational, analytical, prospective and cohort study was carried out between June and September 2022, including 60 patients with breast cancer who underwent radical unilateral mastectomy. Two groups of 30 patients each were formed: one received PECS II Block plus EV Analgesia and the other only EV Analgesia. Inclusion criteria included patients with ASA physical status 1 or 2, aged 18 to 70 years, and those with drug allergies, serious illnesses, and those who refused to participate were excluded. Primary variables included pain intensity, need for rescue analgesia, and presence of adverse effects. Results: Patients who received EV Analgesia alone reported higher values of pain measured by the Visual Analog Scale compared to those who received PEC II Block plus EV Analgesia, with significant differences (p = 0.001). In terms of adverse effects, all patients in the PECS II Block and EV Analgesia group experienced no negative effects, while in the EV Analgesia only group, 100% required rescue analgesia, and there were reports of vomiting, headache and nausea. Conclusion: PECS II Block in combination with EV Analgesia proved to be more effective in postoperative pain control in patients undergoing unilateral mastectomy for breast cancer, significantly reducing the need for rescue analgesia and the occurrence of adverse effects compared to EV Analgesia alone
