简要总结
This single-center prospective observational study will screen 200 parturients with combined lumbo-epidural anesthesia in the First People's Hospital of Lianyungang City, collect the basic information of the patients, as well as the scores of PSQI, STAI, NRS, SSRS and other scales one day before surgery, and analyze their effects on the expression level of BDNF. On the day of surgery, 10mL of peripheral arterial blood and 3 mL of cerebrospinal fluid were collected, and the expression levels of BDNF-TrkB signaling pathway (ProBDNF, mBDNF, TrkB, P-CREB and ALB) were measured, respectively. The patient's EPDS and HAMD-21 scores were evaluated and collected by a professional psychologist at 1 day before surgery, 7 days after surgery, and 42 days after surgery, and the correlation between BDNF expression level and the occurrence of postpartum depression was statistically analyzed, as well as which in cerebrospinal fluid and blood was more sensitive for predicting postpartum depression.
详细描述
On the day before delivery, the anterior will explain the purpose of the test to the pregnant woman during the preoperative follow-up, and collect the basic information of the pregnant woman (age, gender, BMI, gestational age, education level, economic status) and the scores of PSQI, STAI, NRS, SSRS and other scales after obtaining the consent of the pregnant woman and signing the informed consent form. On the day of surgery, an anesthesiologist with more than five years of work experience collected 3ml of peripheral blood and 0.5ml of cerebrospinal fluid before anesthesia administration, and measured the expression level of BDNF-TrkB signaling pathway (ProBDNF, mBDN). 1 day before delivery, 7 days and 42 days postpartum were evaluated by a psychologist with more than five years of work experience and collected the patient's EPDS and HAMD-21 scores, the data collection for 1 day before delivery was carried out in the ward, and the follow-up at 7 days and 42 days after delivery was carried out through WeChat questionnaire link and telephone, if no response was received, WeChat contact and phone reminder would be made again after 1 and 2 weeks, if there was still no response, the subject was considered to have missed the postoperative follow-up time and was regarded as missing follow-up, Statistical analysis was performed to analyze the correlation between BDNF expression level and the occurrence of postpartum depression, and which was higher in cerebrospinal fluid and blood for predicting postpartum depression. If the EPDS score is ≥ 9 points, the HAMD-21 score is ≥ 9 points, and the mother has no suicidal tendencies, psychologists will provide psychological support treatment until the score returns to normal; If the woman is suicidal, it is recommended that the patient and her family have agreed to be admitted to the hospital. Subject files will be kept for up to 5 years after the study is completed.
