Abstract: With the continuous development of medical technology, more and more pregnant women choose cesarean section, but the pain after uterine rupture is inevitable. They will get hurt if no measures are taken for postoperative analgesia. This paper introduced a safe and effective postoperative analgesia after cesarean delivery, that is, micro-flow infusion of anesthetics through continuous, quantitative, accurate, and safe intravenous infusion recognized at home and abroad. Because of a limited dose of postoperative anaesthetics, the implementation of micro-flow continuous infusion is particularly important in ensuring maternal postoperative analgesia effect without producing side effects. Besides the micro-flow continuous infusion of anesthetics, a remote analgesic management and monitoring system was used to provide accurate infusion dose and help medical staff check patient’s infusion volume. A large number of test data were used to verify the stability of the system, aiming to achieve the best analgesic effect after cesarean section.
