Summary
Brief summary (as posted)
The aim of this observational study is to evaluate the effect of Pectoral Nerve Block II (PECSII) on the development of pain in the acute and chronic periods in female patients over the age of 18 who underwent oncological breast surgery. The main questions it aims to answer are: Is PECSII blockade applied to patients undergoing oncological breast surgery effective on acute pain scores compared to the non-blockade group? Is there a difference between the group with block and the group without block in terms of the development of chronic pain in the evaluation made at the 3rd month after surgery? The analgesia method applied to the patients will be recorded in the patient files and acute and chronic pain scores will be evaluated. Chronic pain score evaluation will be made by telephone survey.

Primary outcomes (1)
- measure
- Evaluation of the effect of PECSII block on the development of chronic pain in patients undergoing oncological breast surgery
- timeFrame
- 3 months
- description
- Female patients over 18 years of age, non-pregnant, cooperative, and who agreed to participate in the study, who underwent oncological breast surgery, were contacted by phone in the 3rd month post-operation and evaluated for the development of chronic pain using the PAIN Detect pain scale.Only patients who received routine intravenous analgesia and patients who received PECSII block in addition to routine intravenous analgesia were included in the study. The patients were divided into two groups. The development of chronic pain in the block group was compared with the patients in the non-block group. The surgical technique applied to the patients was recorded from the patient files. The relationship between surgical technique and pain occurrence was evaluated.
