Abstract:
Objective:To understand the clinical application of magnesium sulfate injection in inpatients of the obstetrical department, and analyze retrospectively its rationality and existing problems.Methods:The clinical data of obstetric inpatients who used magnesium sulfate injection in the hospital information system of our hospital from September 2022 to January 2023 were collected. Based on the drug instructions, guidelines for the diagnosis and treatment of hypertensive disorders in pregnancy, domestic and foreign guidelines, and literature reports, the rationality of magnesium sulfate injection in terms of obstetric medication indications, dosage and administration, and treatment course was evaluated.Results:A total of 303 obstetric patients were included in the use of magnesium sulfate injection, with an age of 32 (ranging from 18 to 44) years and a gestational age of 14 to 40 weeks. Among them, 33 cases were used for threatened abortion, 141 cases for threatened preterm birth, and 129 cases for the prevention of eclampsia attacks. Among the 303 patients, 134 cases (44.22%) had no indications for medication. Among them, 13 patients with threatened abortion were treated for fetal brain protection, and 20 patients with threatened abortion and 101 patients with threatened preterm birth were treated for preventing miscarriage by uterine contraction inhibition. There were 118 cases (38.94%) with inappropriate administration methods, mainly due to inappropriate usage and dosage, as well as overly long treatment courses. Of them, 26 cases (22.03%, 26/118) used for brain protectors of premature fetuses were not given loading doses, 15 (12.71%, 15/118) cases had a total medication duration of more than 48 hours, 76 cases (64.41%, 76/118) used for the prevention of eclampsia were not given loading dose, and 1 case (0.85%, 1/118) received rapid infusion time of the loading dose more than 30 minutes. Among the 303 patients, 3 patients presented nausea and vomiting, constipation, and skin flushing, respectively.Conclusions:Nearly half of the magnesium sulfate injection used in obstetrics department in our hospital has inappropriate indications and over one-third has non-standard usage, dosage, and treatment courses. Clinicians should comprehensively assess the patient′s condition and strictly follow recommended methods in the guidelines and drug instructions for standardized use.
