Blood Pressure Support in ICU Sharjah

What is haemodynamic support?

"Haemodynamic" simply means the way blood moves around the body. Every organ depends on a steady flow of blood carrying oxygen, and that flow depends on enough blood volume, a heart that pumps well, and blood vessels with enough tension to keep pressure up. When one or more of these fails, blood pressure falls and organs start to struggle. Doctors call this state shock.

Haemodynamic support is the set of treatments that restores the circulation while the underlying cause is dealt with. At Dar Al Kamal Hospital, Sharjah, it is given in the intensive care unit, where your relative's blood pressure is watched beat by beat and treatment is adjusted minute to minute. It buys time: it keeps the brain, kidneys, heart and gut supplied with blood while the team treats whatever caused the pressure to drop.

Who needs it

Your relative may need blood pressure support if their pressure stays low despite first treatment on the ward or in the emergency department, or if signs of poor blood flow appear, such as confusion, very little urine, cold mottled skin or rising lactate on blood tests.

The common causes are:

• Severe infection. Sepsis widens and weakens blood vessels so pressure falls; more on this is on our sepsis management page.
• Bleeding. Blood loss from an injury, the gut, or after an operation leaves too little volume to fill the circulation.
• Heart problems. A heart attack, a rhythm disturbance or a weakened heart muscle may leave the pump too weak to push blood around.
• Severe allergy. Anaphylaxis makes blood vessels suddenly relax and leak.
• Severe dehydration or other conditions that drain the body of fluid.

Often more than one cause is at work, and the team looks for each of them.

What happens

Support is built in layers, matched to what your relative's circulation needs at that moment.

• Fluids. A drip refills the circulation. Where bleeding is the cause, a blood transfusion replaces what was lost.
• Medicines that tighten blood vessels. These raise the pressure by restoring tension in vessels that have gone slack.
• Medicines that strengthen the heartbeat. These help a tired heart pump more blood with each beat.
• A central line. These medicines are strong, so they are given through a thin tube placed in a large vein in the neck, chest or groin, using infusion pumps that deliver tiny, exact amounts.
• An arterial line. A fine tube in an artery, usually at the wrist, shows the blood pressure continuously on the monitor, so doses can be fine-tuned. You can read more on our invasive monitoring page.

Alongside this, the team treats the cause: antibiotics for infection, stopping a bleed with the surgical or gastroenterology team, or treating the heart with the cardiology team. Doses rise and fall many times a day as your relative responds. If other organs such as the lungs or kidneys also need help, this becomes part of wider multi-organ support. Kidney support is planned with the nephrology team, or by transfer to a hospital that provides the treatment needed.

A detail worth knowing: hands, feet, fingertips and even the nose often feel cold or look pale or bluish while these medicines are running. This is expected. The medicines direct blood towards the brain, heart and kidneys first, so the skin receives less for a while. The nurses check these areas regularly, and colour and warmth usually return as the doses come down.

Preparing for it

Blood pressure support usually starts quickly, but there are helpful things your family can do.

• Share the medical history. Heart conditions, recent surgery, bleeding problems, allergies and any recent illness all help the team find the cause.
• Bring a list of medicines, especially blood thinners, blood pressure tablets and heart medicines.
• Choose one family contact who receives updates and passes them on, including to relatives abroad following events from another time zone.
• Tell the team your relative's wishes, any advance decisions they have spoken about, and religious or cultural needs you would like respected.
• Write your questions down. Useful ones include: what is causing the low pressure, how much support is needed today, and is that more or less than yesterday?

Visiting arrangements are explained by the unit when your relative is admitted.

Afterwards

As the cause settles, the medicines are reduced step by step while the team watches that pressure holds. Many families find this stage encouraging, and it is often a real sign of progress, although doses can go up again if the pressure dips. Once your relative's circulation is stable on their own, the central and arterial lines are removed and they can move towards a ward.

Weakness, tiredness and poor appetite are common afterwards. Nutrition is planned by the ICU team, with dietitian and physiotherapy input arranged by referral where helpful.

After going home, contact your doctor or the hospital on 06 599 7777 if dizziness, fainting, a racing heart or swelling appear, and call the emergency services at once for chest pain, severe breathlessness, collapse or signs of bleeding.

Cost and insurance

Most UAE health insurance plans cover intensive care, including blood pressure support. Because ICU admissions are usually unplanned, insurers need prompt notification and continuing approval during the stay, and some plans set limits. The insurance office at Dar Al Kamal Hospital, Sharjah can guide your family through this on 06 599 7777.
