The kidneys of a newborn are among the least mature organ systems at birth, and their vulnerability to injury and dysfunction is significantly higher than at any later point in life. When a newborn's kidneys fail, whether from a congenital abnormality, perinatal asphyxia, sepsis, or another cause, the consequences accumulate rapidly. Waste products build up in the blood, fluid balance is disrupted, and electrolytes shift in ways that threaten cardiac and neurological function. Without renal replacement therapy, a critically ill newborn with acute kidney failure cannot survive. With it, many do.
At KIMS Cuddles at KIMS Hospitals, neonatal dialysis in Electronic City Bengaluru is available for critically ill newborns requiring renal replacement therapy within our neonatal intensive care unit. For families across Electronic City, Hosur Road, Anekal, and South Bengaluru, this level of specialist neonatal renal support is available locally.
Why Newborns Develop Acute Kidney Injury
The neonatal kidney is uniquely susceptible to acute injury. Perinatal asphyxia, where inadequate oxygen delivery around the time of birth causes ischaemic injury to the kidneys, is one of the most common causes of neonatal acute kidney injury and frequently requires renal support in the days following birth. Sepsis and septic shock, congenital heart disease causing reduced renal perfusion, nephrotoxic medications including certain antibiotics and antifungals, and congenital renal abnormalities are all established causes.
Prematurity adds an additional layer of vulnerability, as the preterm kidney has even less functional reserve than the term newborn kidney, and the combination of prematurity with any additional insult significantly raises the risk of clinically significant kidney failure.
Peritoneal Dialysis in Newborns
Peritoneal dialysis in newborn care is the most commonly used modality of renal replacement therapy in neonates, and for good reason. It uses the peritoneum, the membrane lining the abdominal cavity, as a natural dialysis membrane. A small catheter is placed into the peritoneal cavity, through which dialysis fluid is instilled, allowed to dwell for a defined period during which waste products and excess fluid pass from the blood into the dialysis fluid across the peritoneal membrane, and then drained.
The advantages of peritoneal dialysis in the neonatal context are significant. It does not require vascular access of the size needed for haemodialysis, it is a continuous rather than intermittent therapy that avoids the haemodynamic shifts associated with intermittent blood purification, and it is technically feasible in even the smallest and most premature babies.
Our team at KIMS Cuddles at KIMS Hospitals, Electronic City manages peritoneal dialysis in critically ill newborns with the close monitoring and frequent adjustment of parameters that this therapy requires in the neonatal population.
Neonatal Haemodialysis and Continuous Renal Replacement Therapy
Neonatal haemodialysis and continuous renal replacement treatment are available in neonates when peritoneal dialysis is not possible or has failed to produce adequate clearance. These procedures pass the infant’s blood through an outside circuit to filter waste products and extra fluid and return the cleaned blood to the newborn.
The technical challenges of extracorporeal blood purification in neonates are significant. Circuit quantities are small relative to the baby’s total blood volume, there is the risk of hypothermia from blood chilling in the circuit and precision is necessary in regulating fluid balance in a very little patient, hence specific knowledge and equipment are required.
Our neonatal renal support in Electronic City team has the clinical experience and the appropriate equipment to perform continuous renal replacement therapy in neonates, with close collaboration between our neonatology and paediatric nephrology teams to ensure that decisions about modality, dosing, and anticoagulation are made with the full picture of each baby's clinical status.
Monitoring and Managing Neonatal Kidney Failure
Early identification of acute kidney injury in newborns is the first step toward effective management. Our team monitors urine output, serum creatinine, electrolytes, and fluid balance closely in all critically ill newborns, with a low threshold for escalating to specialist nephrology review when kidney function is deteriorating.
When renal replacement therapy is initiated, the frequency of monitoring increases further, with hourly fluid balance assessment, frequent electrolyte checks, and careful attention to the haemodynamic status of the baby throughout. Dialysis support length varies from days to weeks depending on the underlying reason and the course of renal recovery.
Underlying Causes and Long-Term Outlook
The prognosis for neonatal acute kidney injury depends significantly on the underlying cause and the degree of injury sustained. Many newborns who receive timely renal replacement therapy for reversible causes, including perinatal asphyxia and sepsis, recover meaningful kidney function over the weeks following the acute episode. Those with congenital renal abnormalities or severe irreversible injury may have long-term renal implications that require structured follow-up into childhood and beyond.
Our team discusses the likely trajectory and long-term outlook with families as early as the clinical picture allows, ensuring that the information provided is honest, current, and sensitive to the emotional demands of having a critically ill newborn.
Family Support During Neonatal Dialysis
Having a newborn on dialysis is an experience that is difficult to prepare for. The equipment, the monitoring, the clinical activity around the cot, and the uncertainty about the outcome all place enormous demands on families. Our team at KIMS Cuddles at KIMS Hospitals, Electronic City provides regular, clear communication to parents about what the dialysis is doing, how the baby is responding, and what the next steps in management are, at every stage of the treatment course.
