Steroids for In-Hospital Cardiac Arrest

Neurologically favorable survival after cardiac arrest remains dismal, with a prevalence of severe disability ranging from 25% to 50%.  In previous preliminary work by Mentzelopoulos et al, patients resuscitated with vasopressin, steroids, and epinephrine (VSE) had less organ dysfunction and improved survival.  The question of whether the addition of steroids is beneficial in terms of neurologically favorable outcomes was addressed in the recent study led by Spyros Mentzelopoulos, MD, and colleagues at three centers in Greece.

This study was a multicenter, randomized, double-blind, placebo-controlled, parallel-group clinical trial.  Patients with in-hospital cardiac arrest requiring vasopressors were included.  The control group was  treated according to the European Resuscitation Council (ERC) 2005 Guidelines, with a saline placebo provided in lieu of the steroid.  Patients in the experimental group (VSE group) received arginine vasopressin, epinephrine, and one dose of methylprednisolone (40 mg).  Surviving patients in the VSE group received stress-dose hydrocortisone (300 mg /day) for up to seven days post-arrest. The primary endpoint was return of spontaneous circulation for 20 minutes or longer and survival to hospital discharge with a favorable neurological recovery as assessed by the Glasgow-Pittsburgh Cerebral Performance Category.  Several secondary endpoints were also studied, including complications related to steroids.  Multivariable regression techniques, including a Cox regression analysis, were used to analyze data.

Of 364 patients with cardiac arrest, 138 were ultimately included in the control group and 130 were assigned to the VSE group. VSE patients received less epinephrine and had shorter duration of advanced life support compared to the control group.  Patients in the VSE group had a lower hazard of poor outcome (hazard ratio, 0.70; 95%  confidence interval [CI], 0.54-0.92; P=0.009) and were more likely to be alive at the time of discharge with a favorable neurological status (odds ratio, 3.28; 95% CI, 1.17-9.20; P=0.02).  Patients in both groups who survived more than four hours had similar ventilator-free days and duration of hospital stay.

Steroids may help attenuate the systemic inflammatory response syndrome and improve cerebral perfusion, though the exact mechanisms of action remain unclear. Limitations to this study include lack of data regarding pre-arrest endocrine status, post-arrest myocardial function, and the use of 2005 ERC protocols for cardiac arrest compared to more recent guidelines.  Moreover, the role of steroids remains unclear for cardiac arrest patients in the pre-hospital environment.  Although several studies have cast doubt on the efficacy of epinephrine in terms of improved outcomes for patients with cardiac arrest, when vasopressors are combined with steroids, the effects of vasopressors may be enhanced.  The positive results observed in this trial of VSE in cardiac arrest merits further investigation before adoption in the next iteration of advanced cardiac life support guidelines.

    The role of steroids in cardiac arrest and AMI,though not established,yet I found in 3 of my cases,remarkably recovered during an Acute emergency.I am a primary care physician,a Commandant Medical in the Border Security Force,in India.I have case studies of young individuals 23 to 26 year old who had developed Acute STMI ,with hypotension, in shock,unresponsive with Glasgow coma scale 5/6.These individuals were sent from the periphery without any medication.The possibility of oral aspirin was remote due to the state of shock.Oxygen inhalations at the rate of 6 ltrs per minute started,Inj Hydrocortisone 100 mg iv stat &Inj Decadron 4mg iv stat was administered,Inj Adrenaline 0.5 ml sc administered to accelerate the heart as no AED was available at our centre.Inj Deripylline 1 ampoule was administered IV. Within seconds the patients recovered from their state of shock,and were responsive.Resorted to IM Diclofenac 75 mg to combat the pain,sorbitrate ,clopidrogel,aspirin,atorvastatin was given orally as per the patients requirement and the patients evacuated to the Cardiology deptt of the Medical college,where the cardiac management was done.
    I had been able to revive another 2 cases who were in the age group of 45-50 yrs known cases of T2DM,HPTN with Hypercholesterolaemia ( who had similar such episodes due to noncompliance of medications as above) and had recovered remarkably from cardiac shock,though the textbooks spellout that steroids have no role in such emergencies.

    I forgot to mention vasopressin was also administered to all these patients to maintain the perfusion level during the evacuation
