Effects of Interpectoral-Pectoserratus Plane Block After Breast Cancer Surgery

The aim of this study: It was aimed to observe the effects of intraoperative and preoperative PECS II block on postoperative pain, amount of analgesic use and shoulder joint range of motion in patients who underwent breast cancer surgery. This research was planned as an observational study. For this purpose, patients who underwent breast cancer surgery in İzmir Bakırçay University Çiğli Training and Research Hospital General Surgery Clinic will be included in the study at the 1st hour after the operation. Patients who underwent preoperative Interpectoral - Pectoserratus Plan Block in the operation will be included in Group 1, patients who have been applied Interpectoral - Pectoserratus Plan Block between the muscle planes by the intraoperative surgeon will be included in Group 2, and patients who have not applied any block will be included in Group 3. Pain numerical rating scale (numering Rating Scale) at postoperative 1st, 2nd, 6th, 12th and 24th hours in patients, patient recovery scores (QoR15 Turkish version), amount of tramadol used in patient-controlled analgesia, time to first rescue analgesia, adverse events (pneumothorax, nausea, vomiting, itching, hematoma, allergic reactions) and quality of life, shoulder joint range of motion, hand grip strength (also on day 1) and disability level will be measured on postoperative day 10. H0- Preoperative interpectoral - pectoserratus plane block affects the level of postoperative pain. H1- Preoperativeinterpectoral - pectoserratus plane block does not affect the level of postoperative pain. H2- Intraoperative interpectoral - pectoserratus plane block affects postoperative pain level H3- Intraoperative interpectoral - pectoserratus plane blockk does not affect the level of postoperative pain.
