Exploring the link between circadian rhythm and pain after cesarean section

Circadian Rhythm Status and CS (Cesarean Section) Postoperative Pain

Observational The Second Affiliated Hospital of Chongqing Medical University · NCT05446636

This study is testing how a woman's body clock affects pain levels after having a cesarean section to help improve pain management for new moms.

What this trial studies

This observational study aims to investigate the relationship between maternal circadian rhythm status and postoperative pain following cesarean section. Participants will wear a Huawei wristwatch to monitor their circadian rhythms, while their pain levels will be assessed using a Visual Analog Scale (VAS) after undergoing elective cesarean sections with combined spinal-epidural anesthesia. The study focuses on women aged 20 to 45 who are at 37-42 weeks of gestation and meet specific health criteria. By analyzing the data collected, researchers hope to uncover insights that could improve pain management strategies for postpartum women.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 20 to 45 who are undergoing elective cesarean sections and meet the specified health criteria.

Not a fit: Patients with severe systemic diseases, psychiatric disorders, or those unable to cooperate with the study may not benefit from this research.

Why it matters

Potential benefit: If successful, this study could lead to better pain management techniques for women recovering from cesarean sections.

How similar studies have performed: While the specific approach of using wearable technology to assess circadian rhythms in relation to postoperative pain is novel, similar studies have explored the impact of circadian rhythms on various health outcomes.
