Q

Renal hypertension complicates…

A

kidney disease of any kind. Sodium retention by the kidney leading to water retention and an increased blood volume is usually a factor

Q

in 1st trimester of pregnancy, what happens to BP

A

marked vasodilation causes a drop in systemic vascular resistance which sees BP fall in all women – exaggerated effect in hypertensive women

Q

complications of hypertension in pregnancy

A

Fetal growth restriction  poor placentation – NICE advocates USS at 28-30 weeks and 32-34 weeks to indentify and monitor SGA
Placental abruption - 1% of pregnancies – smoking aids significantly to this risk
Severe hypertension - acute pharmacological management – labetalol, hydralazine, nifedipine
Super-imposed pre-eclampsia high risk, significant protein 300mg suggestive of preeclampsia – Uric acid raised

Q

chronic hypertension - non-pregnancy treatment and care

A
  • Majority of women with proven hypertension will be on one or more anti-hypertensive drugs – ACE inhibitor (enalapril or lisinopril) or an angiotensin receptor blocker (losartan or irbesartan) beta-blocker (atenolol)

medical management and care in pregnancy for hypertension

A
  • Blood pressure meds reduced or stopped in first 20 weeks

  • Mother (renal and liver failure, intracerebral bleeds, eclampsia, HELLP syndrome (haemolysis, elevated liver enzymes, low platelets), disseminated intravascular coagulation, liver rupture and death
21
Q

pre-conception issues and care for preeclampsia

Study These Flashcards
A

aspirin (75mg) from 12 weeks

22
Q

medical management and care pregnancy preeclampsia

Study These Flashcards
A
  • Inpatient care
  • BP should be treated with first-line oral labetalol if more than 150/100
  • FBC, U&E, LFTs should be measured 2-3 times a week
  • USS for growth, AFI and umbilical artery doppler
  • TED stockings
23
Q

midwifery management pregnancy preeclampsia

Study These Flashcards
A
  • Measure BP accurately
  • Measure protein
  • If any symptoms, transfer care to doctors and get opinions
  • Psychological support
24
Q

labour medical management preeclampsia

Study These Flashcards
A
  • Corticosteroids for fetal lung maturation
  • Blood tests
  • Delivery
  • Avoid syntometrine or ergo
  • BP closely observed
  • CTG
  • FBC , U&E and LFTs if not performed in last 2-3 days
  • Continue antihypertensives
25
midwifery care preeclampsia labour
- Hourly BP - Call for urgent help if review - Do not limit second stage unless needed - Oxytocin - Prepare for preterm delivery
26
medical management postnatal preeclampsia
- Close observation of BP - Obstetric review - Repeat bloods 48-72 hours after if indicated - Start antihypertensives if never medicated - Continue meds – reduce once under 130/80
27
midwifery care postnatal preeclampsia
- BP check 4 times daily - BP once 3-5 days - Refer for medical care if BP >150/100
28
gestational hypertension
- Describes new hypertension in 2nd half of pregnancy in absence of protein - 10% of women
29
severe preeclampsia and eclampsia
- Systolic BP >160mmHg or diastolic >110mmHg 2 times with protein and other clinical features
30
severe preeclampsia symptoms
- Severe headache - Visual disturbances - Epigastric pain - Liver tenderness - Clonus - Papilloedema - Platelet count <100 - Abnormal liver function - HELLP syndrome
31
eclampsia
- One or more generalised convulsions on the background of pre-eclampsia - Fatality rate 1.8% up to 35% of women suffer major complication
32
medical management and care antenatal severe preeclampsia and eclampsia
- BP high – urgent intervention - IV administration of labetalol or hydralazine often becomes necessary and use follow local guidelines - Fluid restriction is advised to reduce fluid overload - Restriction – evidence of postpartum diuresis - IV mag sulph – halves risk of eclampsia – 24 hr prior to delivery - 4g slow IV 5 min – 1g/hr for 24 hr - Continue after 24 hrs post birth or 24 hrs post seizure - Recurrent seizures – 2-4g bolus or increase infusion - Magnesium toxicity – reduced urine output, loss of deep tendon reflexes, decreased resps - Diazepam and thiopentone can be used (rare)
33
midwifery care severe preeclampsia and eclampsia
- One-on-one care HDU, hourly output, reflexes, resp, BP - Well documented fluid balance - IV infusions - six 12 hrly blood tests
34
postnatal cares preeclampsia and eclampsia
- 24-48 hr HDU - Debrief - 4 days inpatient , baby SCN - BF support
35
HELLP syndrome
- Haemolysis (RBC rupture – drop in HB level) - Elevated liver enzymes (raised alanine transaminase (ALT) or aspartate transaminase (AST) liver damage - Low platelets (cell fragments involved in clotting process) - Multi-system disorder characterised by activation of the coagulation system leading to increased deposition of the protein fibrin throughout the body - Can occur postnatally
36
differential diagnoses - HELLP syndrome
- Acute fatty liver – nausea, vomiting - Haemolytic uraemic syndrome-thrombotic thrombocytopenic pupura – haemolytic anaemia, low platelets, renal failure, severe headache - Exacerbation of systemic lupus erythematosus (SLE) chronic inflammatory disease affecting multiple organs
37
complications - HELLP syndrome
- Disseminated intravascular coagulation - Placental abruption - Acute renal failure - Pulmonary oedema - Liver haematoma and rupture
38
cardiovascular disease
diseases of the heart and blood vessels
39
examples of CV disease
ischaemic heart disease stroke hypertensive heart disease aortic aneurysms atrial fibrillation congenital heart disease endocarditis peripheral artery disease
40
rheumatic heart disease
-acquired -caused by rheumatic fever -Group A strep -developing countries (ATSI)
41
cardiomyopathy
- inflamed, enlarged and weakened heart muscle - hereditary - viral infection/bacterial - fungal or parastitic infection - ischaemia
42
other valve, atrial and ventricular defects
- marfan syndrome (inherited disorder that affects connective tissue) - Eisenmengers syndrome - Down syndrome - Brugada syndrome - Wolff-parkinson white syndrome
43
effect on pregnancy - CV disease
- 4% affected - most common cause of indirect maternal death in developed world - pre-conception counselling - accurate assessment - collaborative team
44
treatment CV diseases
 minimise complications - Pharmacology – antihypertensives, diuretics - Rest - Optimum delivery method - Appropriate anaesthesia - Appropriate management PP
45
renal changes
- Changes to the renal system - Higher renal plasma flow - Higher GFR (glomerular filtration rate – how well your kidneys filter blood) - Higher kidney size - UTI rates higher - Overt proteinuria
46
congenital renal disease
- Primary defects of the kidney tissue (parenchymal disease) * - Obstruction of the urinary tract (hydronephrosis with obstruction) - * Hydronephrosis without obstruction - * Cystic diseases - * Metabolic diseases * - Syndromes
47
acute renal disease
- Infection : e. coli - Hemolytic uremic syndrome - Nephrotic syndrome - Poisioning
48
chronic renal disease
- Diabetes - Hypertension - Glomerulonephritis - Cancer - Medicine

measuring renal function
- Dipstick - 24 hr collection – protein/creatine ratio - Haematological creatinine
