The aim of this study was to evaluate the efficacy of serratus anterior plane (SAP) block, pectoserratus plane (PECS II) block, and erector spinae plane (ESP) block on postoperative acute pain, quality of recovery and chronic pain in breast cancer surgery patients.
Breast cancer is the most common type of cancer in women. Although surgical treatment is effective and curative, it is associated with many complications in the postoperative period. Acute pain after surgery is one of them. Approximately half of women undergoing breast surgery describe significant post-operative pain (>5 on the Visual Analogue Scale; VAS) score that is not always effectively controlled by standard post-operative treatments. Poorly controlled postoperative pain has been associated with impaired functional recovery, delayed discharge from the post-anesthetic care unit, and prolonged hospital stay. In addition, poorly managed acute pain becomes chronic and is described as 'post-mastectomy pain syndrome'. Regional techniques can reduce acute and chronic postoperative pain. The development of ultrasonography (US)-guided regional anesthesia has led to the development of fascial plane blocks. Serratus anterior plan (SAP) block, pectoserratus plan (PECS II) block, and erector spina plan (ESP) block are frequently used for postoperative analgesia in patients undergoing breast surgery. he aim of this study was to evaluate the efficacy of serratus anterior plane (SAP) block, pectoserratus plane (PECS II) block, and erector spinae plane (ESP) block on postoperative acute pain, quality of recovery and chronic pain in breast cancer surgery patients.

It is planned to include ASA I-III patients between the ages of 18-65 who are planned to undergo breast cancer surgery
Exclusion Criteria:
Before the surgery, US-guided SAP block will be performed
Other: SAP block group
Before the surgery, US-guided PECS II block will be performed
Other: PECS II block group
Before the surgery, US-guided ESP blockwill be performed
Other: ESP block group
No intervention
Other: Control group
US-guided SAP block is performed approximately 30 minutes before the surgery in patients undergoing breast cancer surgery in a separate regional anesthesia room with standard anesthesia monitoring.
US-guided PECS II block is performed approximately 30 minutes before the surgery in patients undergoing breast cancer surgery in a separate regional anesthesia room with standard anesthesia monitoring.
US-guided ESP block is performed approximately 30 minutes before the surgery in patients undergoing breast cancer surgery in a separate regional anesthesia room with standard anesthesia monitoring.
No intervention
postoperative opioid consumption
All patients will receive a standard patient controlled analgesia (PCA) protocol. The postoperative opioid consumption will only be recorded.
Time frame: 24 hours
recovery quality
The Quality of Recovery-15 (QoR-15) is a 15-question questionnaire validated to assess poetoperative recovery. This questionnaire assesses patients' pain, physical comfort, physical independence, psychological support, and emotional status in the erly postoperative period. The patient is asked to express their status scoring from 0 to 10; therefore, the total score ranges from 0 to 150 points.
Time frame: 5 minutes
chronic pain
Patients will be telephoned 3 months after the operation and the presence, localization, and intensity of the pain, its character, and its relation with rest and/or activity will be recorded by asking only verbally.
Time frame: 3 months
Plan to share: No
