椎管内阻滞分娩镇痛的研究进展（Research progress of intra spinal block labor analgesia）

椎管内阻滞分娩镇痛的研究进展（Research progress of intra spinal block labor analgesia） Research progress of intra spinal block labor analgesia Whole network release: 2012-07-19 20:42 published: Huang Shaoqiang, 1188 people have visited Spinal block is the most effective way of labor analgesia, the American Society of Obstetrics and Gynecology and anesthesiologists regard it as the preferred way of labor analgesia. A large number of studies show that it does not increase the rate of cesarean section, but may extend to the second stage of labor, increase equipment delivery rate. Because of the good maternal analgesia and sympathetic nerve activity is blocked, the blood perfusion of the uterus, placenta material exchange to better maintain the acid-base status of the fetus and newborns have improved maternal satisfaction is high, so it is a way of analgesia is the most recommended. Even in women with severe PIH and pre eclampsia, epidural block still provides safe and effective analgesia for natural delivery, thereby reducing the rate of cesarean section. Optimization of patient controlled epidural analgesia (PCEA) delivery model Patient controlled epidural analgesia at present most of the spinal canal block analgesia with low concentrations of local anesthetics and analgesics (PCEA), compared with the continuous infusion method, PCEA more individual, reduce the dosage of the drug, but in the PCEA administration mode, whether it should be combined with continuous infusion of certain the dispute. Boselli think the United background of continuous infusion of PCEA relative to no background infusion of PCEA drug consumption increased significantly, but no further improve the analgesic effect and maternal satisfaction, but may prolong the production process. More studies have suggested that the combined infusion of PCEA does not significantly increase anesthetic dosage, but the analgesic effect is more satisfactory. Therefore, this may be the most widely used method. The reasons for incon
