How is it repaired?

What part of the back do these occur most often?

A

Defect bulge in the vertebrae that is a little more obvious with pouching due to vertebrae not closing. No nerve tissue involved though.

Surgical repair is needed

Low back

Q

What do you use to cover the sac pouch for neural tube defects like meningocele and myelomeningocele?

how to make sure you’re prepared?

A

wet/sterile dressing to maintain sterile and protect from infection

  • this is especially important due to proximity of poop
  • saline should be in warmer so it is ready

Q

What positioning do we put infant in for meningocele and myelomeningocele?

Why does surgery take so long?

A

Prone position or on tummy to keep them from rolling onto the sac until recovered

Surgery can only happen 16-18 hours later bc they hav to to know the extension of the problem
- how much tissue, nerves, other defects (bc midline defects means other defects are likely)

Q

With meningocele and myelomeningocele care what do we need to monitor for neurologically? And why?

A

Hydrocephalus and ICP due to spinal fluid not being able to drain from ventricles as it is supposed to or the fluid is being reabsorbed
- need to know which one tho in order to treat it

25
What does Hydrocephalus affect?
Blood flow and thus oxygenation Internal pressure ulcers and damage
26
How do they mainly treat and manage Hydrocephalus?
Surgical method - Ventriculostomy - Shunt
27
What is a Ventriculostomy surgery for Hydrocephalus?
Surgically perforating the wall of the third ventricle to drain CSF into interpenduncular cistern
28
Types of shunts they can do for surgical repair of Hydrocephalus?
Ventriculoperitoneal - located in the peritoneal cavity and most common bc of flexibility Centriculoatrial - rt atrium location Ventriculopleural - chest location Lumbo-peritoneal - only for communicating hydropecephalus
29
Main concerns with the use of shunt for Hydrocephalus?
ICP due to occlusion Infection from foreign object
30
What is an extra ventricular drain? Risks? But why use it?
External shunt infection risk and make sure you know how stopcocks work so you don't turn the wrong way keep ports covered d It measures pressure. Levels with trachea and cartilage.
31
What is Meningitis?
``` CNS infection (viral, bacterial , TB) - the type of organism will drive the treatment ```
32
Cause of Meningitis?
1) Vascular dissemination or travels through blood from somewhere else in the body - most common 2) Implantation after trauma 3) Anatomic abnormality
33
What does the Meningitis cause?
Inflammation, edema, ICP and damage to brain tissue
34
Treatment for meningitis?
Depends on the agent Viral: supportive Bacterial : treatable with med s
35
Neonate so 1 month old meningitis symptoms
``` Poor feeding & sucking Vomiting / diarrhea Poot muscle tone Hyper or Hypothermia Jaundice Irritability Seizures Full fontanel as late sign ```
36
3mo-2 years old Meningitis
``` Fever Bulging fontanel Poor feeding Seizures Headache Irritability ```
37
2 years and up Meningitis
``` Fever Irritability Headache Opisthotonus Positive Brudzinksi & Kernings ``` Clotting issues leading petichae and purpura Arching back due to the inflammation and to release tension (nucchal rigidity )
38
Brudzinski sign
Flexing of the hip the knee when neck is flared and is painful when there is meningitis
39
Kernels sign
90 degree angle and raised leg that causes pain and occurs with meningitis
40
What will happen to glucose and protein if it is bacterial meningitis? What else will they culture? Testing?
Glucose will drop Protein rises if the cause was bacterial Will culture blood and urine Rapid antigen testing
41
What is a PCR diagnostic test for meningitis?
Polymerase Chain Reaction - Can tell you if it is viral or bacterial - if bacterial, give antibiotics
42
What if the wbc shift is small? What if the wbc is large?
Means viral meningitis Means bacterial meningitis
43
What if the meningitis is suspected of being disseminated intravascular coagulation (DIC)?
Coagulation panel
44
What do we do with someone who is suspected of meningitis?
We isolate them and we get treatment for anyone who has been in contact with them.
45
What treatment do we start out with if meningitis is suspected? Next?
Broad spectrum IV antibiotics first but then narrow it down after lumbar puncture is done and we know the organism - lumbar puncture being cloudy is not god
46
What position do we keep those wit meningitis in?
Elevated to help drain the fluid from the head
47
What precautions will someone with meningitis be on? meds?
Isolated but also seizure precautions with anti-seizure meds | - headache may be present too
48
With antibiotics administration what do we want to give before? Why?
Steroids like dexamethasone as to avoid inflammation and ICP from Cytokine Cascade The antibiotics may break down the cell wall and allow fragments of the membrane to to cause inflammation
49
How can we prevent meningitis? How can meningitis effect the elderly?
Vaccinate - especially young and elderly They're already at risk from reduced motor skills, hearing, and cognition issues. We don't want any secondary effects occurring from the meningitis.
50
What is Encephalitis? Examples of causes?
Inflammation of brain from viral illness Herpes, Respiratory infection
51
Signs of Encephalitis? Treatment of Encephalitis?
Alteration in short term memory like not being able to remember names IV antivirals that shorten the illness
52
Reyes Syndrome defintion What can make this worse?
Encephalopathy characterized by viral infection that can lead to hepatic, metabolic, neuro failure Using aspirin - so don't give this to kids. Salicylates
53
What is Guillain Barre' ?
Progressive motor weakness that travels upwards due to infection from the nerves being affected - bottom peripheral and distal affected first like legs
54
Major concerns with Guillain Baree?
Respiratory depression bc it affects breathing muscles Fall risk bc it starts from bottom and goes up
55
What is recommended for Guillain Barre patients? When is another Time Guillain barre can also happen?
PT to learn how to use muscles again Post pregnancy due to hormones shifting
56
What is the major thing to remember about treating head injuries?
We aren't treating the head injury but we are preventing the secondary injury
57
T/F Having a seizure means you have epilepsy
False. To be an epileptic, you must have 2 or more seizures that are not caused by anything else - bc you can have seizures
58
Classifications of seizures
Focal : Limited area in the brain with abnormal firing but there are seizures taking place . Motor response is not always involved though so may not even see it and can be simple with motor signs, sensory signs, impaired awareness. Generalized : Abnormal firing in a large area such as a whole hemisphere of the brain and there is a muscle response that can be seen that result in Tonic or Clonic responses.
59
Tonic Generalized Seizure Clonic Generalized Seizure
Stiffening up for 10-20 Stiffening with jerky movement
60
What is meant by Post stage seizure?
Stage where the effects go on
61
Focal seizure that is partial with motor signs
A seizure of the a limited area of the brain due to it being focal And Small response like lip smacking or hand smacking. and it appears on one side
62
Focal seizure that is simple partial with sensory signs
Limited area of the brain seizure that produces sensory issues like numbness, paresthesia, or pain in one area of the body. Posture change from muscle relaxation and visual sensations
63
Focal seizure with impaired awareness What will you have?
Period of altered behavior Can have auras and impaired consciousness. You won't remember it.
64
T/F Generalized seizures or seizures that happen in large areas are always either tonic or clonic.
False! | It can be both called a Tonic-Clonic generalized seizure and be followed be a postictal phase
65
In a tonic clonic seizure, how long does each portion last
Tonic for 10-20 seconds - stiffening contractions and often may fall to the ground Clonic for at least 30 seconds but can last half or longer - you will see violent jerking movement from rhythmic
66
Explain the tonic phase
Immediate loss of consciousness, falls to ground even. Eyes roll upward Not breathing, apnea Increases salivation not swallowing
67
Explain the clonic phase
Violent jerking Foaming at mouth Incontinent urine and feces
68
Postical phase
Appears relaxed, but is semiconscious or confused with poor coordination. - not out of the woods - very sleepy
69
What are generalized absence seizures? When do they go away? How often can these happen?
Unrecognizable seizures almost that happen to kids 4-12 years old that is mistaken for inattentiveness or daydreaming - the seizure Vetter discussed Go away with puberty Absence seizures can happen multiple times throughout the day 20 or more
70
What are Atonic and Akinetic generalized seizures When do these happen a lot tho? Can you outgrow these?
Sudden abrupt momentary loss of muscle tone You fall without the ability to break the fall essentially and can happen anytime in the day Can happen shortly after being awake Yes they can be outgrown
71
What are Generalized Myoclonic seizures? Important thing to differentiate? Is there a postictal state with Myoclonic seizures? Do you lose consciousness with Myoclonic seizures? Is it symmetric?
Sudden brief contractures of muscle that can be once or continuous. - not a jerky movement but a contraction No postictal state You can or can't be unconscious It can or can't be symmetric
72
Where do they start with diagnosis of seizures?
A very thorough history and physical | - can even include prenatal care
73
When a skilled observation of a seizure is happening (usually to help dx) what is needed?
Full description of what is happening , location, consciousness level, type, and how long it lasts - document carefully
74
What is the most useful tool for diagnosing seizures?
EEG - confirms abnormal electrical discharges - helps focus in on what type of seizure
75
Why is the keto genie diet recommended for seizures?
The high fat, low carbs, and low protein induces keto to keep seizures at bay
76
What is surgery like for seizure treatment?
Remove any area that interferes with electrical firing of brain or separate hemispheres; removal of epileptic foci
77
How are vagal nerve stimulator a good option for management of seizures? Programing?
The stimulator goes in the chest/collarbone, wires wrap around legs and vagal nerve, and then the single overrides the seizure Programming can be continuous for 30 sec every 5 minutes or activated for demand of the seizure
78
Vagal nerve stimulator complications?
Coughing, swallowing hoarseness Infection Tingling All from excessive stimulation
79
Larzepam use?
Most common seizure med and used in emergencies
80
Diazepam use? route? What do we need to do for this med so it work properly?
Can be given rectally for seizures Make sure to dilute with saline tho bc it can sticking interact to plastic
81
Seizure meds that start with a P?
Phenytonin | Phenobarbital
82
What can seizure meds interact with?
Liver issues Bone marrow - RBC/WBC development
83
What are Febrile seizures? What age group is this most common in?
Seizure activity related to fever above 100.4-102 Infant - 5 years
84
Management for seizures including febrile?
Put the child on their side Do not try to put anything in the mouth or restrain the child
85
When to seek medical attention with febrile seizures?
If seizures are repetitive Last longer than 5 minutes Child is difficult to arouse after the seizure - the child may be tired but you should be able to arouse them
86
What to educate parents about febrile seizures
The temp is causing it and to pay attention to whether they are recurrent, lasting longer than 5 minutes, and can't arise the child.
