What is sarnat Thompson score?

The HIE score (Thompson score) is a clinical tool comprising of a set of clinical signs associated with CNS dysfunction. It is used to assess status of a child following birth asphyxia [10–13]. In the scoring system, a score of 0 is normal and the maximum score is 22 which signifies the worst possible status of HIE.

What is sarnat scale?

In medicine Sarnat staging, Sarnat Classification or the Sarnat Grading Scale is a classification scale for hypoxic-ischaemic encephalopathy of the newborn (HIE), a syndrome caused by a lack of adequate oxygenation around the time of birth which manifests as altered consciousness, altered muscle tone, and seizures.

What are the stages of hypoxic ischemic encephalopathy?

Table I.

How is hypoxic ischemic encephalopathy diagnosed?

To confirm a diagnosis of HIE, a neurologist will examine your baby, who will be monitored by an electroencephalogram for seizures and signs of brain dysfunction and undergo neuroimaging tests, such as magnetic resonance imaging (MRI), to check for signs of brain injury.

Can you live a normal life with hie?

Many infants with mild HIE have a normal outcome (temporarily, at least), but babies with severe HIE have a high mortality rate. Roughly 80% of survivors show neurological sequelae signs. Infants with mild HIE classify under Sarnat Grade 1. The severity of HIE can reach a maximum at Stage III.

What is Downe score?

Downes score is used as an alternative. to evaluate clinical respiratory distress if blood gas analysis. instrument or pulse oxymetry is not available. Objective To evaluate the validity of Downes score for assessing. hypoxemia in neonates with clinical respiratory distress.

What is sarnat stage1?

In stage 1, infants exhibited hyperalertness, hyperreflexia, sympathetic autonomic responses, and a normal EEG. When present, stage 1 typically lasted from 1 to 18 h. In stage 2, infants displayed obtundation, mild hypotonia, flexor posturing, parasympathetic responses, and seizures.

Can you live a normal life with HIE?

Can a baby fully recover from HIE?

Brain injuries from HIE often result in physical disabilities and cognitive impairment. A smaller percentage of babies with HIE have great outcomes. These children fully recover and experience only mild, if any, symptoms of neurologic injury.

Can you recover from hypoxic brain damage?

A full recovery from severe anoxic or hypoxic brain injury is rare, but many patients with mild anoxic or hypoxic brain injuries are capable of making a full or partial recovery. Furthermore, symptoms and effects of the injury are dependent on the area(s) of the brain that was affected by the lack of oxygen.

Is HIE a disability?

It is also known as intrapartum asphyxia. This kind of oxygen deprivation occurs during labor and delivery. HIE can lead to brain damage, and often to a disability like cerebral palsy. The degree of disability varies by individual and is highly dependent on how long the baby was lacking oxygen.

What is expiratory grunting?

Grunting is an expiratory sound caused by sudden closure of the glottis during expiration in an attempt to maintain FRC and prevent alveolar atelectasis.

Is the Sarnat score used in too many cases?

Although in existence for 43 years, the Sarnat score is documented sub-optimally or not at all in many cases of neonatal encephalopathy. In a recent national review of neonatal encephalopathy cases, the Sarnat score had been assigned in only half of the cases2. The reasons for the low application of the scoring tool are numerous.

What should my total Sarnat score be for HIE?

A total Sarnat score of ≥5 when performed at <6 hours of age detected future disability. Clinicaltrials.gov: NCT01747863. Hypoxic-ischemic encephalopathy (HIE) assessment after birth is presently dichotomous: those who do or do not qualify for therapeutic hypothermia, a treatment that should be initiated within the first 6 hours of birth.

When do you take the modified Sarnat test?

Modified Sarnat examination at <6 hours of age in infants with mild HIE with disability and summary of predictive values for each of the Sarnat categories.

Where can I get a Sarnat Grading Scale?

3 Section of Neonatology, Department of Paediatrics, University of Calgary Cumming School of Medicine and Alberta Children’s Hospital Research Institute (Owerko Centre), Calgary, Alberta, Canada. 4 Department of Pediatrics and Neurology, Stanford University, Stanford, California.
