How to dilute hydralazine and how to give in preclampsia bp-180/100mmhg, asthmatic 20 week pregnancy



Thank you for sharing the case. Hydralazine is mostly not use in these day. Magnesium sulfate is drug of choice. 4gm + 50 ml NS dilution can be given for loading dose. Later 5gm MgSO4 IM 6 hrly.. With strictly monitoring BP, Urine out & reflexes like knee jerk ,ankle jerk. Any reduction in above parameters are indication of stopping injection. All these should be done under obstratition observation.
