İNTRATECHAL MORPHİNE GROUP: Addition of intrathecal morphine as an adjuvant to local anesthesia in routine spinal anesthesia application and multimodal analgesia applications
Erector Spinae Plane Block: Application of erector spinae plane block and multimodal analgesia applications at the end of the operation after routine spinal anesthesia application
Study summary
Working Title The Effect of Intrathecal Morphine and Erector Spina Plan Block on Serum Cytokine Levels and Chronic Pain in Caesarean Section Surgery
Study Description This study aims to evaluate the effects of intrathecal morphine added as an adjuvant to local anesthesia during spinal anesthesia and the erector spinae plane block applied at the end of cesarean surgery on postoperative serum cytokine levels, pain intensity, need for rescue analgesia, hospital anxiety and depression levels, quality of obstetric recovery, and the development of chronic postoperative pain.
Study Type Study Design: Observational Model: Two parallel groups Time Perspective: Prospective
Interventions Intervention Type: Drug and Block Procedure Details: In patients included in the study, intrathecal morphine is administered as an adjuvant to local anesthesia during spinal anesthesia first group. At the end of surgery, an erector spinae plane block is performed other group.
Primary Outcome Measures Serum Cytokine Levels Time Frame: 0., 6. and 24. Hours Assessment Method: Serum biochemical analyses
Pain Intensity and Need for Rescue Analgesia Time Frame: 2., 4., 6., 12. and 24. hours, assessed using the Numeric Rating Scale(NRS)
Hospital Anxiety and Depression Levels Time Frame: Preoperative and at 24 hours postoperatively Assessment Method: Hospital Anxiety and Depression Scale (HADS)
Quality of Obstetric Recovery Score Time Frame: At 24 hours postoperatively
Chronic Postoperative Pain Development Time Frame: Evaluated at 4 months postoperatively Assessment Method: Short Form McGill Pain Questionnaire-2

Primary outcome measure(s)
postoperative serum cytokine — 24 hours We aimed to investigate the effects of intrathecal morphine administered as adjuvant in spiral anesthesia and erector spina plan block performed at the end of the operation on postoperative serum cytokine (Interleukin-6, Tumor Necrosis Factor-alpha, Interleukin-10) levels.
In order to evaluate the basal serum cytokine levels from each patient, 5 milliliters (ml) of venous blood will be taken before the operation (after monitoring-before spinal anesthesia). In order to evaluate the changes in serum cytokine levels after the operation, the moment when the first blood sample is taken will be considered as the beginning; 5 ml of venous blood will be taken at the 6th and 24th hours. Although many time periods are stated in the literature for the control of cytokine levels (6, 11, 12), the hours planned for the control blood samples were determined as the 6th and 24th hours, considering the start and end times of the effects of the methods used in the study arms.
Chronic pain — 4 months We aimed to investigate the effects of intrathecal morphine administered as adjuvant in spiral anesthesia and erector spina plan block performed at the end of the operation on chronic pain in patients undergoing cesarean section surgery.
The assessment will be made with the McGill Short Form Pain Questionnaire-2. The questionnaire consists of 22 items. Each question is evaluated with a Numeric Rating Scale. A low score is associated with less pain, while a high score is associated with more pain.
