Neurodevelopmental Outcome Expert Witness
Neurodevelopmental disorders are conditions that affect a patient’s nervous system as he or she grows and matures. It means that the patient’s brain, nervous system, and cognitive ability are impaired.

A patient who presents with nerve or spinal cord damage has an impaired ability to sense the world around him; it is also possible that his reactions to stimuli will be slowed or eliminated. Unfortunately, if nerve damage is severe, it cannot be reversed. Instead, it can be treated with palliative drugs or surgery.
Nerves either send signals to the brain from the body or to the body from the brain; therefore, any damage to the patient’s nerve impairs his or her sensation of the world around him/her. Nerve damage can range in severity and be treated with surgery or drugs.
Nephrology is a field of internal medicine; it emphasizes the study of the kidney. Nephrologists diagnose and treat kidney diseases. They use a variety of techniques to do so, including dialysis and renal transplants.
One of AME’s nephrology expert witnesses has written two exclusive medical malpractice articles that we have provided, for your interest, below. Mild Hyponatremia: new risk of memory changes, gait disturbances and death
Hyponatremia: Hyponatremia is defined as a lower than normal serum sodium concentration using routine laboratory testing of serum electrolytes. Although chronic hyponatremia below 120 mEq almost universally prompts medical investigation, milder forms are usually overlooked or disregarded as being of little clinical significance. Recently, mild-moderate hyponatremia (i.e., a serum sodium concentration >125-135 mEq/L) has been associated with distinct symptoms as well as with increased mortality after hospitalization.
What causes hyponatremia? Many conditions are associated with chronic hyponatremia, the single most common electrolyte abnormality. These include inflammation in the brain or lung, cancers, thyroid disease, kidney disease, heart failure, and several categories of medications such as oral hypoglycemics (used in patents with diabetes mellitus), narcotics, diuretics, and antidepressants, particularly those agents referred to as selective serotonin receptor inhibitors (SSRI agents).
What are the consequences of mild hyponatremia? Recent epidemiologic evidence associates mild hyponatremia (average 131 mEq/L) with impairment of short-term memory as well as an abnormal gait. While both deficits are concerning, the risk of fall is significant (more than double compared to patients with a normal serum sodium), especially in the elder population at greatest risk for hip and femoral fractures.
Standard of Care: Serum sodium should be evaluated in all patients receiving routine laboratory testing for serum electrolytes, glucose and kidney function. The finding of a serum sodium concentration below 135 mEq/L should prompt inquiry for associated changes in short-term memory, as well as an evaluation of gait. If either are implied, a search for the cause of hyponatremia is important in normalizing these parameters, thereby potentially reducing the risk of short-term memory loss, the likelihood of falling due to an unsteady gait, and decreasing the risk of mortality, particularly in patients with underlying chronic disease conditions.

Dialysis Unit Communication – Real Time or Real Problem
Dialysis Unit Communication: At present there are more than 6500 dialysis centers in the Untied States that provide life saving care for patients with end stage renal disease (ESRD) requiring in renal replacement therapy. This often thrice-weekly form of treatment has become commonplace in virtually every major city and suburb in the US. Dialysis care is almost universally provided by Nephrologists (physicians specializing in the diagnosis and treatment of kidney diseases) in close collaboration with a team of health care providers that includes specially trained dialysis nurses technicians, social workers and dieticians. Dialysis care is now considered sufficiently routine that the Nephrologists need not be present during each treatment.
Potential Consequences of Dialysis:
Potential Consequences of Dialysis: As with any procedure, hemodialysis carrels a small but significant risk of complication including infection, low blood pressure, and bleeding. The risk of choric blood loss is real, even under ideal conditions; however, blood los may also be acute, especially in patients with plastic dialysis catheters that are susceptible to accidental disconnection during or after the dialysis procedure.
Standard of Care: Recent evidence suggests that hemodialysis units widely vary in standardizing communication when untoward vents occur in the absence of the Nephrologist. While some units report any unit ward event, others elect not to inform the Nephrologist, potentially causing these events to be unaddressed, thereby increasing the risk of recurrence, complications and even death. Partly as a result to this variability in practice, it is necessary for physician to review the “event threshold” that mandates communication between the Dialysis Unit and Nephrologist in order to prevent or minimize or the risk of dialysis related complications that jeopardize the patients’ well being. It is also clear that the absence of documentation that communication has in fact occurred increases liability in cases of these unfortunate complications.

Neonatal resuscitation is an emergency procedure in which physicians perform CPR and other life-saving techniques on an endangered fetus. If the condition of the unborn baby begins to deteriorate, medical professionals must work quickly to save the fetus and the mother.
Neonatal nursing is a medical specialty in which nurses monitor an unborn baby and the pregnant mother in order to immediately detect any conditions that could make the pregnancy and/or delivery riskier. Nurses use a variety of emerging technologies to diagnose and treat diseases in the fetus or mother.
Neonatal neurology is a medical specialty in which physicians examine an unborn baby in a pregnant woman to see what mental and neurologic conditions exist. Early detection and treatment of any such diseases is essential to saving the baby, the mother, and ensuring a safer delivery.

Neonatology is a medical specialty (closely associated with pediatrics) in which physicians care for newborn infants. The most common conditions that they treat include prematurity, birth defects, or birth asphyxias. Typically, neonatologists work in hospitals and intensive care units.
A narcotic is a psychoactive drug that has opiate-like effects. An example of a narcotic is morphine, which is used for medicinal purposes because it induces sleep and relieves pain.
One of AME’s narcotics expert witnesses has written an exclusive medical malpractice article that we have provided, for your interest, below. Narcotic Overdose – Medical Malpractice
Narcotic injections are frequently used in hospitals to control pain, sometimes augmented with the use of tranquilizing medications. However, tranquilizing drugs in combination with narcotics will increase the risk for respiratory depression.
That is, they chemically narcotize the breathing centers in the base of the brain (the medulla) and can stop the patient’s breathing. If this is not recognized immediately, death ensues.
Elderly patients and children are more susceptible to the respiratory depression side effects of narcotics and tranquilizers.
The frequency of injection should be not closer together than every three hours, and the dosage and cumulative effect of combinations of medications must be taken into consideration by both the ordering physician and the treating nurses, both of whom have independent duties to protect patients.
