My father was around 80 years old with history of diabetes, kidney disease, smoker, prostrate issues and his blood pressure was 90/44 when we took him to shifa international hospital, h-8, islamabad, pakistan for treatment. At that time his chest was not properly working as his oxygen saturation was 80%. Instead of taking option of dialysis due to kidney issues, doctors tried to do his echo due to reason best known to them. As he was not cardia patient. He could not lay on the bed therefore doctor gave him serenace injection @2.5 mg. It is pertinent to mention that he was not taking medicine for blood pressure and he was not a patient of blood pressure. As doctors injected serenace injection @2.5 mg, he had cardiac arrest and may be died at the spot around 3: 00 pm on 24th june 2019. They in order to save them, they gave him cpr treatment for around 10 minutes and then he again had breath. He was put on ventilator in order to grab more money and he did not respond for 10 hours till 12: 40 am on 25th june 2019 and then they declared him dead. I want to know about effects of serenace during this treatment. My questions are as followed: is serenace is recommended for patients who have kidney issues, diabetic, prostrate issues and smoker for long time? Was it permissible to inject serenace in order to do echo which was actually not required? Was it necessary to inject serenace @ 2.5 which was high dose? Can they inject serenace without consulting anesthesia doctor? Is assistant consultant can take this decision without consulting consultants dealing with heart and kidney issues? They have killed our patient, what are international standards to deal with such doctors as shifa international hospital claims that they are giving international level take care to their patients? Do you allow your doctors to do same procedure for patients at your hospital?
