Methods: This is a mixed-method study with an explanatory sequential approach. The first stage is quantitative and longitudinal. Participants will be divided into two groups of elective C-sections and parturient women who receive remifentanil. They will be matched concerning social class, type of provider, and birth rank. In the first stage, data will be collected using a socio-demographic questionnaire, Edinburgh"s Depression during pregnancy questionnaire, Labor Agentry Scale, and midwifery-neonatal outcomes checklist within 24 hours after delivery. Participants will be followed up to 30 days after delivery to complete the Edinburgh Postpartum Depression questionnaire. The second stage is a qualitative study to explain the perceptions of parturient women who had either elective C-section or painless delivery (using remifentanil), including factors related to labor experiences. In the third stage, a mixed study will be performed to provide strategies for improving labor experiences.

Discussion: Women"s experiences during cesarean section can have different effects on maternal and neonatal outcomes; Following the use of two methods of continuous analgesia with remifentanil and spinal anesthesia and analgesia caused by these methods in cesarean section, women"s experiences may be different; The protocol presented in this study is a clinical guide to present this important issue (experiences of women during cesarean section looking for an appropriate method of analgesia).
