Application of a small dose of Fentanyl adding into epidural anesthesia in cesarean section
Objective To observe the anesthetic effect of epidural anesthesia adding a small dose of Fentanyl in cesarean section. Methods 218 cases of ASA Ⅰ ～ Ⅱ class full-term pregnancy, maternal fetal head position single with epidural anesthesia for cesarean section were randomly divided into group A (study group 109 cases) and group B (control group 109 patients). L2～3 accepted epidural puncture, amount of 2% Lidocaine 4ml,5min after no signs of spinal anesthesia, A component containing 2 jig/ml additional 2% Lidocaine and Fentanyl and Ropivacaine 0. 75% 5 ml secondly,B group graded an additional 2% Lidocaine and 0. 75% Ropivacaine each 5ml,according to the corresponding block level,local anesthetic could be added until the plane reached T, after painless surgery. To record the time required for block level of Tt ,the initial dose,the maximum block level and duration of action of local anesthet-icsjAt skin incision.into the abdomen,to take birth and sewing the skin to record the VAS score,monitor and record before anesthesia,after injection 5 min,15 min,30 min,surgery time SBP.DBP.HR.SpO2;observe and take into the abdomen during fetal and neonatal responses after birth traction 1 min,5 min Apgar score. Results A group in the skin incision and into the abdomen when the VAS score was significantly lower than group B( P<0.05), and take the child and slit the skin of the two groups no significant difference(P>0.05) ;The highest block level two quite .while the block level up to the time and 1, in group A was significantly less than the initial dose in group B( P<0. 05); Anesthesia duration in group A than B,head(P<0.01) .light traction response in group A in group B(P<0. 05), while BP,HR,SpO2 and Apgar score between the two groups no significant difference(P>0. 05). Conclusion Small doses of local anesthetics combined epidural anesthesia Fentanyl can significantly shorten the onset time of anesthesia,reducing the amount of local anesthetic,enhanced the anesthetic effect,and no significant effect on the newborn, can be safely used in obstetric anesthesia.
