devang171086 Posted May 21, 2014 Share Posted May 21, 2014 Ya We can use mirinone safely in newborn...loading dose 75 ug/kg in 1 hour f/b 5-7ug/kg/min Link to comment Share on other sites More sharing options...
devang171086 Posted May 21, 2014 Share Posted May 21, 2014 In shock n mas developing PPHN Link to comment Share on other sites More sharing options...
nashwa Posted May 21, 2014 Author Share Posted May 21, 2014 it dec SVR .....yes , what mechanism to use it in shock Link to comment Share on other sites More sharing options...
priyabhagwat Posted May 21, 2014 Share Posted May 21, 2014 We use it in postop cardiac surgeris also.to reduce afterload on heart. Sent from my RM-941_im_india_204 using Tapatalk Link to comment Share on other sites More sharing options...
nashwa Posted May 21, 2014 Author Share Posted May 21, 2014 If there is hypotension....can I use it Of course not Usually in neonate, there is vasdilatation of bl v So when I used it Link to comment Share on other sites More sharing options...
devang171086 Posted May 21, 2014 Share Posted May 21, 2014 All d form of shock finally causing heart pump failure.. due to one mechanism is vaso constriction and increase after load...milrinon has action of increase heart contractility and decrease after load by vasodilation...

devang171086 Posted May 21, 2014 Share Posted May 21, 2014 If hypotension due to shock den we of course we can use... Link to comment Share on other sites More sharing options...
devang171086 Posted May 21, 2014 Share Posted May 21, 2014 We use it in our nicu which had got good results ...if shock is not manage by dopamine..we use milrinon along with dopamine Link to comment Share on other sites More sharing options...
nashwa Posted May 21, 2014 Author Share Posted May 21, 2014 Dopamine increase SVR while milrinon decrease it so both had different action Link to comment Share on other sites More sharing options...
devang171086 Posted May 21, 2014 Share Posted May 21, 2014 So wen compensated shock we like to maintain vaso construction and wen thing worse due to vasoconstrition due to un compansation den milrinon act adjuvant ..... Both have also similar action of also..... increase heart contractility ...wen dopa receptor tired milrinone receptor still work for help... 1 Link to comment Share on other sites More sharing options...
priyabhagwat Posted May 21, 2014 Share Posted May 21, 2014 Its simple.just find out cause of shock by echo.if IVC small/ underfilled, use fluid and dopamine.if cardiac contractility poor but still BP at higher side use milrinone.u can not use milrinone in any type of hypotention if BP low.

devang171086 Posted May 21, 2014 Share Posted May 21, 2014 Ya obviously if echo available... Link to comment Share on other sites More sharing options...
kpsanghvi Posted May 25, 2014 Share Posted May 25, 2014 Milrinone is a vasodilator. Useful in PPHN. If 2-D Echo is not available then it will be dangerous to use it in hypotension. Dopamine or epinephrine is better bet. Now epinephrine is increasingly preferred to Dopamine 1 Link to comment Share on other sites More sharing options...
zhr_akbarian Posted June 12, 2014 Share Posted June 12, 2014 We used milrinone with dopamine IV and sildenafil for PPHN. Link to comment Share on other sites More sharing options...
Francesco Cardona Posted June 12, 2014 Share Posted June 12, 2014 Unfortunately this study (http://clinicaltrials.gov/ct2/show/NCT01088997?term=milrinone+neonates&rank=1) has been terminated prematurely. Would have been interesting to find out more about the drugs effects in neonates. Link to comment Share on other sites More sharing options...
ctestolin Posted July 6, 2014 Share Posted July 6, 2014 In our Center, we re-evaluate PPHN treatment in newborn and we introduced Milrinone (I used once with good result). For milrinone use is mandatory a cardiac echography: cardiologist or experienced neonatologist in cardiac echo Here some information about Milrinone that I took from Literature Milrinone actually is a off-label drugs for PPHN in Italy but several times it is used with good results (parents' consensus necessary) Milrinone has a duble effects: - inotropic effect on cardiac output - pulmonary and systemic vasodilatatory effect, with possibile synergic effect with iNO Indication: PPHN NON-responder to iNO with cardiac echo showing left ventricular disfunction. We associate Milrinone plus Adrenalin (Dopamine increases pulmonary resistences thus incerasing afterload of right ventricule; Dobutamine worses cardiac performances during left ventricole disfunction) Dosing (based on literature): - gestazional age < 30 weeks: loading dose 50-75 microgr/kg in 60 min, manteinance dose 0,375-0,75 microgr/kg/min - gestazional age > 30 weeks: loading dose 135 microgr/kg in 180 min, maintenance dose 0,2-0,75 microgr/kg/min In case of severe systemic hypotension (with total amine dose > 10 microgr/kg/min) the LOADING dose should be reduced to 25 microgr/kg or omitted Maximal duration: 3 days (even if in Literature some authors used milrinone for several days) Since milrinone is metabolized by kidney, reduce loading dose and maintenance dose in case of severe renal impairment REMEMBER: milrinone infusion is NOT compatible with Furosemide (precipitaion of drugs) Milrinone preparation: VIAL: 10 ml e.v. (1 mL=1 mg); diluite 1 ml/kg of Milrinone up to 50 mL of Saline or 5%Glucose (velocity 1mL/h=0,33 microgr/kg/min) Side effets: hypotension (2.9%), supraventricular aritmic pulse (3.8%) or ventricular (12% even if these cardiac efefct are present very rare in pediatric and neonatal population), hyokaliemia (0.6%), trombocitopenia (0.4%) Some Literature: - Carina Teixeira-Mendonc¸aa, Tiago Henriques-Coelhob, Pathophysiology of pulmonary hypertension in newborns: Therapeutic indications Rev Port Cardiol. 2013;32(12):1005-12 - Marcia L.
