국내 산과 전문의의 임신 중 고혈압성 질환 임상진료패턴 분석

Abstract

Purpose: The purpose of this study was to investigate the clinical practice patterns of Korean obstetricians and gynecologists the diagnosis and management of hypertensive disease in pregnant women. Methods: From April 2015 to October 2015, questionnaire was distributed via email to obstetricians who were members of the Society for Maternal and Fetal Medicine. The survey consisted of 37 questions in 6 categories. Responses to the questions on the management of hypertensive disorders of pregnancy, from diagnosis to treatment, were evaluated. Results: A total of 93 obstetricians and gynecologists responded to the survey. High blood pressure was allocated the highest priority as an index mainly used when deciding to hospitalize patients with hypertensive disease during pregnancy, followed by pregnancy symptoms, proteinuria, and blood test results. Calcium channel blocker (CCB) for oral administration and hydralazine for injection were preferred as antihypertensive drugs mainly used to control severe hypertension. Regarding the delivery method for hypertensive disease during pregnancy, in cases of preeclampsia, 63% of the respondents chose the delivery method according to the cervical status, and in cases of hemolysis, elevated liver enzymes and low platelets (HELLP) syndrome and eclampsia, which increased in severity, 52% and 31% responded that the delivery method was determined according to the cervical status, respectively. In cases of mild preeclampsia, the 70% of respondents preferred 37–38 weeks of gestation for the delivery time. Regarding the use of aspirin in patient with hypertension during pregnancy, 52% of the respondents occasionally administered aspirin, and in patients with a history of hypertensive disease during pregnancy, only 43% were administered prophylactic aspirin. Conclusion: Domestic obstetricians regarded blood pressure as the most meaningful factor when treating women with hypertension during pregnancy and considered blood pressure control as important. The preferred antihypertensive agents were oral CCB and hydralazine injections, and the choice of delivery method was determined according to the condition of the cervix and severity of the disease. Even in women with high risk factors for preeclampsia, prophylactic aspirin was administered in as low as 50%, of patients, possibly may due to the absence of domestic guidelines for aspirin use during pregnancy. Korean guidelines for prophylactic aspirin administration during pregnancy is needed based on additional research on the efficacy of aspirin for domestic women in the future.
