A comparative study of the effect of different doses of intrathecal fentanyl on the quality and quantity of analgesia in cesarean section of multiparous mothers in Ali Bin Abitalib Hospital, Zahedan...

this anesthesia method is associated with side effects such as nausea, vomiting and itching; Therefore, this study was conducted with the aim of determining the effect of different doses of intrathecal fentanyl on the quality and quantity of pain-free time in cesarean section of multiparous mothers.This randomized clinical trial study was conducted on 60 pregnant women who volunteered for multiple elective caesarean section with spinal anesthesia. In this study, subjects were randomly divided into two treatment groups (bupivacaine and fentanyl (with doses of 15 and 25 micrograms)) and were finally analyzed by SPSS version 26 statistical software.The maximum level of sensory block in the 25 micrograms fentanyl group was significantly higher than the 15 micrograms fentanyl group. The maximum recovery time of motor block in the 15 micrograms fentanyl group was significantly higher than the 25 micrograms fentanyl group. The complication of vomiting in the 15 micrograms group was significantly higher than the 25 micrograms group, however, the onset time of sensory block, the maximum degree of sensory block, the quality of anesthesia during surgery, the duration of surgery, the patient's vital signs during surgery, and anesthesia complications such as itching and nausea had no statistically significant difference between the two studied groups.it can be stated that the treatment with bupivacaine and fentanyl (with doses of 15 and 25 micrograms) did not have a statistically significant difference in anesthesia indicators and anesthesia complications (except the maximum level of sensory block, maximum recovery time and vomiting complication)
