Why Patients Choose Apollo Hospitals Lucknow for CRRT

• Part of the Apollo Hospitals Group, established in 1983 ? over four decades of experience in Indian tertiary care, with a network-wide protocol library for critical care nephrology and acute kidney injury (AKI) management.
• Apollo Hospitals Lucknow is a multi-speciality tertiary care facility on Kanpur Road, Sector B, LDA Colony, serving patients from across Uttar Pradesh and adjoining states. Bed strength, ICU bed counts and unit-specific capacity are confirmed by the hospital at the time of enquiry.
• A dedicated nephrology and critical care team. CRRT at Apollo Lucknow is delivered jointly by consultant nephrologists, intensivists, and trained ICU nursing staff. The current number of nephrologists and intensivists on the panel, and their individual years of experience, are listed on the hospital's own "Find a Doctor" listing and confirmed at reception ? we do not quote a figure that may change.
• CRRT is available inside the intensive care setting, so the therapy is delivered at the bedside without moving an unstable patient to a separate dialysis floor.
• Modality flexibility. The commonly used CRRT modes ? SCUF, CVVH, CVVHD and CVVHDF ? can be selected and switched based on whether the priority is fluid removal, solute clearance, or both.
• چوبیس گھنٹے سپورٹ سروسز that CRRT depends on: 24-hour emergency department, blood bank access, laboratory for serial electrolytes, arterial blood gases and coagulation studies, and interventional radiology or bedside ultrasound guidance for dialysis catheter placement.
• Multidisciplinary case discussion with cardiology, pulmonology, gastroenterology and hepatology, infectious disease, and clinical nutrition ? important because most CRRT patients have sepsis, heart failure, liver disease or poisoning alongside kidney failure.
• Anticoagulation options including heparin-based and heparin-free circuits, decided case by case for patients with bleeding risk or low platelet counts.
• Care across age groups. Adult CRRT is offered routinely. Availability of paediatric or neonatal CRRT with low-volume circuits varies by unit staffing and equipment, and should be confirmed directly with the hospital before transferring a child.
• Transition planning. Patients who recover partially are stepped down to intermittent haemodialysis or SLED, and those who do not recover are counselled about maintenance dialysis or transplant evaluation, with follow-up in the nephrology OPD.
• سائٹ پر انشورنس اور TPA ڈیسک for cashless pre-authorisation, government scheme paperwork where applicable, and itemised billing queries.

جائزہ

Continuous Renal Replacement Therapy (CRRT) is a specialised treatment designed for patients with acute kidney injury (AKI) or severe fluid overload. At Apollo Hospitals Lucknow, we aim to provide advanced, protocol-driven CRRT care with modern technology, working towards the best possible patient outcomes. Our team of skilled nephrologists and critical care specialists develops treatment plans tailored to each patient's clinical situation. With a focus on clinical rigour and patient trust, Apollo Hospitals Lucknow serves as a referral option for critically ill patients in and around Lucknow who need continuous renal support.

CRRT is not a routine outpatient procedure. It is an intensive care therapy, almost always started in an ICU on a patient who is too unstable for conventional dialysis. Understanding this distinction helps families set realistic expectations about the intensity of monitoring, the duration of the ICU stay, and the fact that CRRT supports the kidneys while the underlying illness is treated ? it does not by itself cure the cause.

CRRT کیوں ضروری ہے۔

CRRT is a life-supporting procedure that plays a crucial role in managing patients with severe kidney dysfunction. Unlike traditional dialysis, which is typically performed intermittently over three to four hours, CRRT operates continuously, allowing more gradual and controlled removal of waste products and excess fluid from the bloodstream. This is particularly useful for critically ill patients who may not tolerate the rapid fluid shifts associated with conventional dialysis.

The medical importance of CRRT is considerable. It helps maintain electrolyte balance, removes uraemic toxins, corrects acid?base disturbances, and supports overall metabolic stability in patients with AKI. By providing a gentle and continuous approach to renal replacement therapy, CRRT can reduce the risk of haemodynamic complications and improve tolerance of therapy. At Apollo Hospitals Lucknow, CRRT is delivered with continuous monitoring so that prescription changes can be made in real time.

Clinical situations in which CRRT is commonly considered include:

• AKI with haemodynamic instability, especially patients on vasopressor support for septic shock
• Refractory fluid overload with pulmonary oedema, not responding to diuretics
• Severe hyperkalaemia, severe metabolic acidosis, or symptomatic uraemia
• AKI in the setting of acute liver failure or hepatorenal syndrome
• Cerebral oedema or raised intracranial pressure, where rapid osmolar shifts from intermittent dialysis are risky
• Post-cardiac-surgery low cardiac output states with oliguria
• Certain poisonings and drug overdoses, and rhabdomyolysis with myoglobinuric AKI
• Tumour lysis syndrome with rising potassium, phosphate and uric acid

It is important to be honest about the evidence. Large randomised trials (ATN, RENAL, ELAIN, AKIKI, IDEAL-ICU, STARRT-AKI) have not shown that CRRT is superior to intermittent haemodialysis for survival in unselected ICU patients, nor that starting dialysis very early improves survival compared with a watchful, indication-driven approach. What CRRT reliably offers is better haemodynamic tolerance and finer control of fluid balance in unstable patients. Guidelines therefore suggest CRRT preferentially for haemodynamically unstable patients and for those with acute brain injury, rather than as a blanket first choice for everyone.

Clinical Guidelines That Guide CRRT Practice

CRRT decisions at a tertiary Indian centre are generally anchored to the following documents:

• KDIGO Clinical Practice Guideline for Acute Kidney Injury (2012) ? still the reference standard for AKI staging and renal replacement therapy initiation, dosing and modality choice. KDIGO recommends CRRT be used preferentially in haemodynamically unstable patients and in patients with acute brain injury or raised intracranial pressure, and advises a delivered effluent dose of 20?25 mL/kg/hour for CRRT in AKI (which usually requires prescribing a higher dose to allow for circuit downtime).
• KDIGO 2023 Executive Conclusions on AKI and Acute Kidney Disease (AKD) Controversies Conference ? updated the language of AKI/AKD, emphasised that dialysis should be started for clear indications rather than by a fixed timing rule, highlighted regional citrate anticoagulation as the preferred anticoagulation strategy where it can be delivered safely and monitored, and stressed structured follow-up of AKI survivors because of the risk of progression to chronic kidney disease. A full revision of the 2012 AKI guideline has been in development on this basis.
• Indian Society of Nephrology (ISN-India) / Indian Society of Critical Care Medicine (ISCCM) positions ? the ISCCM has published Indian consensus and position statements on renal replacement therapy in the ICU covering vascular access, anticoagulation, dosing and initiation triggers, adapted to Indian resource realities. Indian Society of Nephrology guidance and the ISN-supported AKI registry work also emphasise the high burden of community-acquired AKI in India from sepsis, diarrhoeal disease, tropical infections such as malaria, dengue, leptospirosis and scrub typhus, snake bite, obstetric causes, and native or over-the-counter nephrotoxic medicines.
• Acute Disease Quality Initiative (ADQI) consensus statements on CRRT quality, precision fluid management, and net ultrafiltration rates, which shaped the modern caution against aggressive fluid removal.

What has shifted most recently: the emphasis has moved away from "start dialysis early in AKI" and towards "start when there is a genuine indication, and then deliver the therapy well." Regional citrate anticoagulation has moved to first-line preference in many guideline documents ahead of heparin for CRRT circuits, and slower, more measured net ultrafiltration rates are now favoured over rapid fluid removal. Availability of citrate protocols varies between Indian ICUs; the anticoagulation approach used for a particular patient at Apollo Lucknow is decided by the treating intensivist and nephrologist.

تاخیر کے خطرات

Timely intervention matters. Delaying renal replacement therapy once a clear indication exists can lead to serious complications, including worsening acidosis, dangerous hyperkalaemia, progressive fluid overload, and increased mortality risk. In patients with AKI, the kidneys cannot filter waste effectively, so toxins accumulate. If CRRT is postponed beyond the point of clear indication, this can contribute to cardiovascular instability, arrhythmias, metabolic imbalance, respiratory failure from pulmonary oedema, and multi-organ dysfunction.

At the same time, the evidence does not support starting CRRT before an indication exists ? several trials showed that many patients managed with careful watchful waiting recovered kidney function without ever needing dialysis, and avoided catheter-related complications. The safe position is neither reflexively early nor negligently late: it is close monitoring with prompt action when thresholds are crossed.

Signs that should trigger urgent reassessment in a patient with kidney injury include:

• Breathlessness at rest or when lying flat, or new frothy sputum
• Passing very little or no urine for many hours
• Confusion, drowsiness, hiccups, or seizures
• Rapid weight gain with swelling of face, legs or abdomen
• Palpitations or a documented high potassium level
• Persistent vomiting with inability to keep down medicines or fluids

Apollo Hospitals Lucknow operates a 24-hour emergency service, so patients with these features can be assessed at any hour rather than waiting for OPD hours.

CRRT کے فوائد

Undergoing CRRT at Apollo Hospitals Lucknow offers several potential benefits for patients facing acute kidney failure:

• Improved haemodynamic tolerance: CRRT is generally better tolerated by critically ill patients because it removes fluid and solute slowly, reducing the drops in blood pressure often seen with intermittent dialysis.
• Precise fluid control: Hourly adjustment of net ultrafiltration allows nutrition, blood products, antibiotics and other infusions to be given without pushing the patient into fluid overload.
• ذاتی نوعیت کے علاج کے منصوبے: Nephrologists set the modality, dose, anticoagulation and fluid targets for each patient's physiology, and revise them as the illness evolves.
• جامع نگرانی: Continuous monitoring during CRRT permits real-time correction of electrolytes, acid?base status and fluid balance.
• کثیر الضابطہ نقطہ نظر: Nephrology, critical care, nursing, clinical nutrition, physiotherapy and pharmacy work together, including dose adjustment of antibiotics and other drugs cleared by CRRT.
• Stability for the brain: Because osmolar shifts are gradual, CRRT is preferred in patients with cerebral oedema, acute liver failure or head injury.

Realistically, CRRT supports failing kidneys while the primary illness is treated. It buys time. Whether kidney function recovers depends largely on the cause and severity of the injury and the patient's other organ function.

تیاری اور بحالی

Preparing for CRRT involves several important steps. Because CRRT is usually started as an emergency, much of this preparation happens rapidly and in parallel with resuscitation, with the family consenting on the patient's behalf if the patient is not conscious.

تیاری کے نکات

• مشاورت: Discuss the condition and the need for CRRT with the nephrology and critical care team. This is the time to ask about expected duration, likelihood of kidney recovery, and alternatives.
• طبی تاریخ: Provide a complete history ? current medicines including painkillers, ayurvedic or herbal preparations and over-the-counter drugs, allergies, prior kidney disease, diabetes, hypertension, recent contrast scans, and any recent fever, diarrhoea, snake bite or poisoning.
• Pre-procedure testing: Expect blood tests (creatinine, urea, electrolytes, blood gases, complete blood count, coagulation profile), urine tests, chest imaging and a kidney ultrasound to rule out obstruction, plus screening tests required before dialysis access.
• عروقی رسائی: A temporary large-bore dialysis catheter is placed in the internal jugular, femoral or subclavian vein, usually under ultrasound guidance and local anaesthesia.
• سپورٹ سسٹم: Arrange for family or friends to help during the ICU stay and recovery. In Indian joint families, it helps to nominate one primary decision-maker and one attendant for paperwork, so information is not fragmented across relatives.

ریکوری ٹپس

• طبی مشورہ پر عمل کریں: Adhere to post-CRRT instructions on diet, salt and fluid limits, and medicines.
• سیال کی مقدار: Take fluids as advised. During the recovery phase some patients pass large volumes of urine and need more fluid, while others must still restrict intake. Follow the individual prescription rather than generic advice to "drink plenty of water."
• علامات کی نگرانی کریں: Watch for reduced urine output, swelling, breathlessness, fever, or bleeding or redness at the catheter site, and report these promptly.
• سرگرمیوں میں بتدریج واپسی: Allow time to recover before resuming normal routines, and follow medical guidance on returning to work or exercise.
• باقاعدہ پیروی: Keep nephrology follow-up appointments to track kidney function, blood pressure and urine protein after discharge.

Apollo Hospitals Lucknow supports patients through the whole CRRT pathway, from initiation to post-discharge nephrology follow-up.

Timing of CRRT and the Pre-Procedure Phase

There is no fixed creatinine number at which CRRT must begin. Decisions are indication-based.

• Immediate (within minutes to hours): life-threatening hyperkalaemia with ECG changes, severe pulmonary oedema not responding to diuretics, severe refractory metabolic acidosis, uraemic encephalopathy, pericarditis or seizures, and dialysable poisonings.
• Urgent but planned within the same day: progressive oliguria with rising creatinine and worsening fluid balance in a patient on vasopressors, where CRRT is set up in a controlled way.
• محتاط انتظار: stage 2?3 AKI without the above features, monitored with repeat blood tests and strict input?output charting, since a proportion of patients recover without dialysis.

The set-up phase typically includes consent, catheter insertion and confirmation of position, machine and circuit priming, selection of dialysate and replacement fluids, decision on anticoagulation, and setting of blood flow rate, effluent dose and hourly net fluid removal targets. Machine alarms, filter clotting and circuit changes are routine parts of therapy and do not mean something has gone wrong with the patient.

CRRT Modes and Alternatives Compared

Modality choice is dynamic. Many patients begin on CRRT while on vasopressors, step down to SLED as blood pressure stabilises, and then either recover renal function or move to intermittent haemodialysis.

Procedures Sometimes Performed Alongside CRRT

• Insertion or replacement of a temporary or tunnelled dialysis catheter
• نگرانی کے لیے سنٹرل وینس اور آرٹیریل لائن پلیسمنٹ
• Mechanical ventilation and, where indicated, tracheostomy
• Therapeutic plasma exchange for conditions such as certain vasculitides, thrombotic microangiopathy or Guillain?Barr�syndrome
• Haemoperfusion or albumin-based liver support in selected poisonings and liver failure, subject to availability and clinical suitability
• Percutaneous nephrostomy or ureteric stenting when AKI is obstructive
• Kidney biopsy when the cause of AKI remains unclear and glomerular disease is suspected
• Drainage of collections or source control surgery in sepsis
• Blood product transfusion and nutritional support, including feeding tube placement

This is a general guide only. Actual timelines vary widely with the cause of AKI, the number of organs involved, age and pre-existing kidney disease.

Returning to Normal Activity After Critical Illness and CRRT

Recovery from the ICU stay is often slower than recovery of the kidneys themselves, because prolonged bed rest causes marked muscle loss. Practical Indian-context markers of recovery include:

• Sitting cross-legged on the floor: usually possible once hip and knee flexibility and trunk strength return; do not force it if the femoral catheter site is recent or tender.
• Squatting and using an Indian-style toilet: needs quadriceps strength and balance. Until then, a Western commode or a commode chair over the squat pan is safer, and a grab bar helps. Avoid squatting while a femoral dialysis catheter is in place.
• Sleeping on the floor: acceptable once the patient can get up from the floor unaided. A firmer mattress or a bed is safer during the early weeks.
• سیڑھیاں: attempt with a companion first; breathlessness on climbing may indicate fluid overload or anaemia and should be reported.
• Driving and two-wheeler use: only after strength, reaction time and blood pressure have stabilised and the treating doctor agrees.
• کام: desk work is often possible weeks before heavy manual or field work. Farm labour, construction work and long outdoor shifts in Uttar Pradesh summers carry a real dehydration risk and need clearance and a hydration plan.
• Exercise and sport: begin with walking and supervised physiotherapy, then progress gradually. Contact sport, heavy weight training and endurance events should wait until kidney function and blood pressure are stable and cleared by the nephrologist.
• Religious fasting: Navratri, Karva Chauth, Ramzan or Ekadashi fasts affect fluid and potassium balance and medicine timing. Discuss with the nephrologist before fasting.

Preventing Another Episode of Acute Kidney Injury

Patients who survive AKI carry a higher long-term risk of repeat AKI and of chronic kidney disease, so prevention matters as much as the acute treatment.

• Avoid routine NSAID painkillers such as diclofenac, ibuprofen and their combination powders, which are widely sold over the counter in India.
• Do not take antibiotics, especially aminoglycosides, or contrast-based scans without telling the doctor about your kidney history.
• Avoid unprescribed ayurvedic, siddha, homeopathic or herbal heavy-metal-containing preparations and "kidney tonics" ? several have been linked with AKI and interstitial nephritis in Indian reports.
• Treat diarrhoeal illness, dengue, malaria, scrub typhus and leptospirosis early, and maintain oral rehydration during febrile illness.
• Seek immediate hospital care after snake bite; do not delay for traditional remedies.
• Control diabetes, blood pressure and weight; get urine protein and creatinine checked at the intervals your nephrologist advises.
• Hydrate deliberately during heat waves and outdoor labour, and pause diuretics or other drugs only on medical advice during acute illness.
• Keep vaccinations up to date, and get influenza and pneumococcal vaccination if advised.

Children, Older Adults and Other Special Situations

بچوں

Paediatric CRRT requires small-bore catheters, low-volume circuits, blood priming for infants, and precise weight-based prescriptions. Common indications in Indian children include sepsis, dengue, haemolytic uraemic syndrome, inborn errors of metabolism with hyperammonaemia, and post-cardiac-surgery AKI. Because equipment and paediatric intensive care staffing determine feasibility, families should confirm current availability of paediatric CRRT at Apollo Hospitals Lucknow before arranging a transfer.

پرانے بالغ

Elderly patients often have reduced renal reserve, arterial stiffness, and multiple medicines. They tolerate rapid fluid removal poorly, which is exactly why CRRT can suit them, but they also have higher risks of bleeding, catheter complications, delirium and deconditioning. Goals of care conversations, including whether prolonged organ support is consistent with the patient's wishes, are an appropriate and important part of treatment.

حمل اور نفلی مدت

Obstetric AKI remains an important cause of kidney failure in India, from postpartum haemorrhage, sepsis, severe pre-eclampsia and HELLP syndrome. CRRT in pregnancy or after delivery requires joint obstetric, nephrology and critical care management, with careful attention to volume status and fetal monitoring where the pregnancy is ongoing.

Patients already on maintenance dialysis

Patients with established kidney failure who become critically ill may be temporarily switched to CRRT for haemodynamic reasons, then returned to their usual haemodialysis or peritoneal dialysis schedule once stable.

If CRRT Is Declined or Not Offered

Families sometimes decide, for personal, financial or prognostic reasons, not to proceed with CRRT. This is a legitimate decision and should be made with full information.

• With a hard indication such as severe hyperkalaemia, refractory acidosis or pulmonary oedema, declining renal replacement therapy is usually life-threatening within hours to days.
• Without a hard indication, conservative management with diuretics, potassium binders, bicarbonate, strict fluid balance, nutrition support and treatment of the underlying cause is a reasonable path, and some patients recover.
• Where the overall prognosis is poor because of advanced illness, the team may recommend against escalating to CRRT and instead focus on symptom relief and comfort. Palliative care input can be arranged.
• An alternative to full CRRT ? SLED, intermittent haemodialysis or acute peritoneal dialysis ? may be acceptable when CRRT is not feasible.
• Any decision can be revisited. Choosing not to start CRRT today does not prevent starting it tomorrow if the situation or the family's view changes.

Factors That Influence the Cost of CRRT

CRRT is a consumable-intensive ICU therapy, so billing is driven mainly by how many hours of therapy are delivered and how many circuits are used. Apollo Hospitals Lucknow provides estimates and itemised bills through its billing counter; please ask the reception or insurance desk for current figures rather than relying on third-party price listings.

• Emergency versus planned admission: CRRT is almost always part of an emergency admission. In an emergency, treatment starts first and cashless pre-authorisation is filed alongside ? usually within 24 hours of admission, as required by most insurers.
• کیش لیس راستہ: Present the health insurance card and a photo ID at the insurance or TPA desk. The hospital sends a pre-authorisation request with the clinical notes and estimate; the insurer or TPA issues an initial approval and then enhancement approvals as therapy continues.
• معاوضہ کا راستہ: If your insurer is not empanelled, you pay and claim later. Keep the discharge summary, itemised bill, payment receipts, all investigation reports, pharmacy bills and implant or consumable stickers.
• انتظار کی مدت: Most indemnity policies have an initial waiting period of about 30 days during which only accident-related claims are payable, and longer waiting periods, commonly two to four years, for specified or pre-existing conditions. AKI arising from a covered acute illness is generally payable after the initial waiting period, but a claim linked to declared pre-existing kidney disease may be affected by the pre-existing disease waiting period. Read your policy schedule.
• حادثہ بمقابلہ منصوبہ بند احاطہ: AKI after a road traffic accident, crush injury, snake bite or poisoning is usually treated as accidental and is typically payable from day one under most policies. Personal accident policies may also apply.
• Sub-limits and co-pay: Room rent caps, ICU sub-limits, consumable exclusions and co-payment clauses (common in senior citizen plans) can leave a balance for the family to pay. Ask the desk for a written estimate of the likely non-payable component.
• Non-payables: Gloves, syringes, some dialysis con
