My 10.5-month-old baby went into a coma after medication - what happened?

MY WIFE WAS DIAGONISED WITH ADULT ONSET SCA AT AGE 69. ALL ALONG SHE HAD GOOD HEALTH , VERY ENERGETIC , REGULAR BLOOD TESTS SHOWING ALL PARAMETERS AT NORMAL LEVELS, ALTHOUGH DUE TO HER BELIEF IN VARIOUS RELIGIOUS RITUALS SHE WAS OBSERVING FAST FOR AROUND THREE DAYS PER WEEK . AFTER SCA EXCEPT INVOLUNTARY MOVEMENT WHILE WALKING , SHE WAS OTHERWISE FINE WITH REGULAR PHYSIOTHERAPY EXERCISES TWICE A DAY. AFTER ABOUT SIX MONTHS SHE GOT FEVER AND HER BLOOD , URINE TESTS REVEALED LOW HOMEOGLOBIN , BLOOD OXYGEN AND UTI AFFECTING CRETANINE ALSO. DESPITE ADMINISTERING ANTIBIOTICS , SHE SUDDENLY HAD DIFFICULTY IN BREATHING AND WAS ADMITTED TO A LOCAL HOSPITAL BUT HOPING FOR BETTER TREATMENT WE SHIFTED HER TO AKASH HOSPITAL DWARKA NEW DELHI ON 6TH OCTOBER . FROM EMERGENCY SHE WAS MOVED TO ICU . ON 11TH SHE WAS DETECTED WITH HOSPITAL ICU ACQUIRED BACTERIAL INFECTION , AND SEPSIS . WITH EACH PASSING DAY HER CONDITION DETERIOIRATED , LOW OXYGEN LEVELS AND LOW BP AND WAS PUT ON VENTILATOR SUPPORT WITH DAILY DIALYSIS DUE TO KIDNEY FAILURE . THEN WE WERE INFORMED THAT HER LIVER HAD ALSO BEEN IMPACTED AND FINALLY MULTIPLE ORGAN FAILURE . SHE BREATHED HER LAST ON 26TH OCTOBER . WAS ALL THIS DUE TO HOSPITAL ICU ACUIRED BACTERIAL INFECTION , POOR ICU PROTOCOL ???

My mother aged 89 years stopped eating, drinking speaking in the last week of January. I had her examined in a private hospital and it was found by ecg, CPK MB and troponin test that she had suffered a heart attack and also had pneumonia. Eco cardiography revealed that she had left ventricle efficiency 30 %. She was admitted to ICU and treated with anticoagulants, antibiotics and IV fluids and also given oxygen. Later her blood pressure dropped and she was given nor adrenaline by IV route. A few hours before her death her heart rate was 130 beats per min and breathing was 30 times per minute. I pointed out this to the doctor on duty but he did not do anything. A few hours later she died of cardio respiratory arrest. I feel she could have survived had she been given anti arrhythmic drugs or by using a pacemaker. I feel even five months after her death that she died due to lack of proper treatment and feel depressed when I remember her final moments. Could she have lived if treated in a better hospital?

Good afternoon , Doctor. Was shocked to hear the news of this infant's death on the flight. What could have possibly led to this kind of fatality? More importantly, what precautions must parents take when travelling via air with their infants?
