Critical Care

Critical care (ICU care) is intensive monitoring and support for patients with life-threatening illness — severe infections, major trauma, heart attack, stroke, organ failure, post-major-surgery, obstetric emergencies, paediatric emergencies. Indian ICUs save many lives, but the experience can be overwhelming for patients and families. Understanding the basics helps make informed decisions.

What an ICU provides

• Continuous monitoring — heart, breathing, oxygen, blood pressure.
• Breathing support — oxygen, non-invasive ventilation (BiPAP/CPAP), mechanical ventilation via breathing tube.
• Circulatory support — IV fluids, blood-pressure-supporting drugs, sometimes ECMO in advanced centres.
• Kidney support — dialysis when needed.
• Nutrition — tube feeding or IV nutrition.
• Close control of infections, sedation, pain.
• Multi-disciplinary team — intensivists, nurses, physios, dietitians, pharmacists, social workers.

For families

• Ask for a daily update — diagnosis, what's being done, what's expected next, how the patient is doing.
• Know the treating doctor — name, role, and when they do rounds.
• Ask about costs — many ICU treatments are expensive; insurance coverage, Ayushman Bharat, and hospital schemes can help.
• Second opinion in a complex case is acceptable — not a sign of distrust.
• Advance care planning — for an older or sicker patient, discuss goals of care early. Aggressive ICU care is not always the kindest path; comfort-focused care is a legitimate choice.

Informed consent in ICU

• Ventilation, dialysis, blood transfusions, surgery, do-not-resuscitate (DNR) decisions — all require informed consent, ideally involving the patient where possible and the family otherwise.
• Ask for information in a language you understand; take time, don't be rushed.
• Under Indian law, valid advance directives / living wills are now recognised following the 2018 Supreme Court judgment — if the patient has one, make sure the team knows.

After ICU

• Post-ICU syndrome — muscle weakness, cognitive issues, anxiety, depression, PTSD are common after a long ICU stay. Rehabilitation, counselling, and follow-up help.
• Functional recovery takes weeks to months — be patient, keep up rehab.
• Vaccinations and dental/eye/routine care often get missed — catch up after discharge.
