Q

PROM care plan for GBS + (AOM)?

A

Ideally prenatal discussion.

  • Give SOGC reccomendation: Immediate IOL and Antibiotic prophylaxis
  • discuss research gap regarding most effective approach to preventing EOGBSD
  • Acknowledge and proceed depending on client preferences and values
  • If client choses expectant management at this time, remind client of recommendation for medical IOL for PROM at18hrs & antibiotics at start of labour

24
What colour does positive nitrizine turn?
Dark Blue from yellow, with pH above 6.5
25
How accurate is nitrizine?
Sensitive but not specific Often says 'positive'
26
What is the normal pH of pregnancy vag?
4.5 -6.0
27
What is pH of amniotic fluid?
7.1-7.3
28
What can cause a false positive with ferning (4)?
Antiseptic solution Semen Fingerprints cervical mucus
29
Is ferning a conclusive test?
No, it’s supportive rather than conclusive in non-labouring clients with non-specific vaginal fluid loss
30
What won’t cause a false positive with ferning? (3)
Blood Mec Vaginal secretions (don't ask me what the difference bw from vag secretions and cervical fluids is...)
31
What is a more specific and sensitive test for AF?
Amnisure – more expensive (placental alpha microglobulin-1) The sensitivity ranges from 94.8 to 98.9% and the specificity from 87.5 to 100%;
32
Is it reasonable for someone to stay home with PROM?
Yes, if IOL is declined and VEs avoided. All else: of course they can but higher risks
33
Recommendations for Expectant Mgmt PROM ALARM? (7)
-avoid VEs -observe infection: monitor maternal pulse and temperature FHR uterine tenderness -give abx and IOL ifchorioamnionitis develops -educate to report signs of infection or decreased FM -FM/FHR evaulatued every 24 hours -when in labour after term PROM > 24 hours, EFM in labour is recommended (AOM differs) -asymptomatic healthy term babies born after 24 hours of PROM should be observed for the first 12 hours for signs of infection (AOM routine pp care)
34
What is the CD rate in BC in BC 2021?
37.8 % )
35
What is the CD rate for nulips with spontaneous labour in BC 2021?
24.3 %
36
What is Term PROM?
Term ROM with no ctx for more than 18 hours (which is an arbitrary number)
37
What is the CD rate for nulips with IOL in BC 2021?
52.6 % (2x higher than nulips w spont. labour)
38
What is Prolonged ROM?
ROM in with ctx for greater than 18 hours
39
What are the risks of prolonged ROM?
Increased chance of infection for mom and bb
40
How to monitor prolonged ROM?
Increased surveillance of temp (q2 hours) No Mec/risk factors = IA is fine
41
What causes spontaneous labour?
Not fully known, activated by fetus and caused by cascade of positive feedback loops VAL WISDOM: wow so complex and mysterious, our job = don’t mess with it
42
What is the risk of misidentifying early labour?
Mistaking Early L for Active L can contribute to unnecessary interventions related to ‘failure to progress’
43
Non pharm strategies for coping in early labour?
* Coping strategies prenatally and education around long early labour can be * Continuous support from a support person * Staying at home/home like environment * Focused breathing/meditation * Heat, cold * TENS machine * Intuitive, upright positions * Distracting activities * Positioning:  OP position is associated with longer labours, increased back pain, increased need for pain management, dystocia, and adverse conditions and outcomes  Support optimal fetal positioning by encouraging clients to get into positions such as hands and knees and side-lying  Hands and knees position and sterile water injections can also relieve back pain associated with OP fetal positioning (1,2,3,5)
44
Early labour pharm methods? (4)
-Tylenol and gravol -IM morphine and gravol -IV hydration -IM gravol (hb)
45
Triaging PROM? (10)
Hx GBS status red flags fluid amount time fetal well-being -movement and fetal presentation last time you saw them contraction pattern coping 'are you feeling well',
46
Options to confirm PROM?(5)
Sterile spec and pooling Nitrizine - not accurate, kind of crap - needs to be up in the cervix (not when it's trickled down the vagina with mucus, blood, and urine) Ferning US - not diagnostic, but info that could be relevant "Amnisure" - placental alpha microglobilin test (expensive) (but what is this cost compared to induction - Val wisdom)
47
Can you have baths with PROM
No baths till active labour
48
What is the likelihood of chorio with PROM and no VEs?
Low
49
When is ideal IOL for term PROM?
There is a research gap
50
What does the evidence say about IOL vs exp mgmt. for PROM?
Low Risk term PROM = evidence to support safety of IOL or expectant mgmt
51
What are the issues with TERM PROM RCT?(3)
- Overly broad defn around chorio - More VE for exp mgmt than IOL group - No screening/treating GBS
52
What are abnormal findings where IOL may be a good choice for TERM PROM? (5)
Mec Bad smelling fluid Active vag bleeding Fever above 38 Decreased FM
53
What is the biggest risk factor for infection of birther and babe with low risk term PROM?
Frequent VES before active labour
54
How much does AOM recommend for PROM timing?
96 hours
55
How much does ACOG recommend for PROM timing?
12-24 hours
56
How much does NICE recommend for PROM timing?
24 hours
57
What should be included in monitoring of exp mgmt PROM?(2)
- When/how to page - Daily in person assessments (birthing person’s VS, FHR, FM)
58
Are daily NSTs evidence based for low-risk Term PROM?
Not if we don’t view PROM as a pathology (VAL HOT TAKE)
59
What does SOGC recommend with fetal monitoring in labour for PROM?
CEFM if PROM greater than 24 hours
60
What doess AOM recommend for PROM timing and FHS? (evidence based)
IA is reasonable if no risk factors present (AOM) (no mec or fever)
61
What does WHO say the ideal CD rate should be?
(WHO recommends ideal CD rate 10-15%
62
What is Prolonged early labour?
Latent phase lasting over 14 hours in multip/20h in nullip
63
Risks of prolonged early labour?
Dehydration Exhaustion
64
Non-pharmacological early labour support?
Continuous support person Staying home; music; relaxed breathing; massage; counter pressure; TENS Use of water Intuitive movement, upright position; birth ball, etc Encourage rest, eating, hydration Emotional support and reassurance Fetal position impacts labour: encourage hands and knees; side-lying for OP Sterile water injections
65
GBS stats for ICD?
15-40% of pregnant ppl are GBS pos 40-70% of babies born to GBS pos birther will be colonized if untreated 1-2% of colonized NB will develop infection if untreated 5% of NB who develop infection will die
