(Prosiding) Effect Of Coal Dust Exposure To Mother’s Blood Pressure, Haemoglobin (Hb) Level, And Foetus Heart Beat In Tanah Laut Regency

Abstract

Tanah Laut Regency is one of regencies in South Kalimantan that has coal mine companies. Effects of coaldust exposure can cause oxidative stress and inflammation process that influence endothelial function. Endothelial function is important to motherfoetus circulation. This research’s goal was to analyze the effect of coaldust exposure to mother’s blood pressure, haemoglobine level, and foetus’ heartbeat. The method used observational analyzes with crossectional design. Respondents were at least 30 pregnant women from area with coaldust exposure and without coaldust exposure. Respondents were examined by doctor and midwive to check their bloodpressure, Hb level and foetus heartbeat. Data were analyzed by comparative test. The results were 118.85 mmHg for sistolic bloodpressure from coaldust exposure area and 120.93 mmHg for not-coaldust exposure area (p=0.522); 73.67 mmHg for diastolic bloodpressure from coaldust exposure area and 76.43 mmHg from not-coaldust exposure area (p=0.823); 11.533 gr/dL for Hb level from coaldust exposure area and 11.89 gr/dL from not-coaldust exposure area (p=0.028); 143.21 x/minute for foetus heartbeat from coaldust exposure area and 139.53 x/minute from not-coaldust exposure area (p=0.013). the conclusion was coaldust exposure could effect mother’s Hb level dan foetus’ heartbeat, but could not effect mother’s bloodpressure yet in Tanah Laut Regecy.
