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.

Breast cancer is the most common type of cancer among women and the most common cause of death worldwide. While there has been a serious decrease in the mortality rate due to developments in diagnosis and treatment, there have been serious increases in functional disability and disability due to the disease. Breast cancer can lead to various functional losses due to the nature of the disease itself, radical surgical interventions and radiotherapy applications. These include shoulder dysfunction (pain and limitation of joint movement), locomotor system disorders such as upper extremity muscle strength loss and lymphedema, as well as psychological and cosmetic problems, and as a result, these problems affect the quality of life (QOL) of individuals (1). Firstly, Blanco et al. Ultrasound-guided pectoralis nerve II block (Interpectoral and pectoserratus plan block - PECS II block), described by MD, is increasingly used for analgesia in breast surgery (2). It has been reported that PECS II block is effective in reducing postoperative pain intensity and opioid consumption (3). It is safe and relatively simple to apply as an interfascial plane block, and there is no sympathetic blockade (4). The PECS II block consists of two interfascial injections of local anesthetics: 1) between the pectoralis minor and serratus anterior muscles, 2) between the pectoralis major and pectoralis minor muscles at the level of the third rib. Local anesthetic injection into these planes; It is expected to block the lateral pectoral nerve, medial pectoral nerve, anterior branches of the thoracic intercostal nerves, and long thoracic nerves (5). Recently, the types of local anesthesia used during radical surgery may decrease the postoperative pain levels and recovery times of the patients. The effect of these intraoperative or postoperative blocks on the patients' clinical status in the postoperative period has not been compared before.
