This document discusses problems that can occur with fetal position, presentation, or size during labor and delivery. It describes issues like occipitoposterior position where the baby's head is facing the wrong way, breech presentation where the baby is feet or butt first, face or brow presentations which are types of abnormal head position, and transverse lie where the baby is laying horizontally across the womb. It provides information on assessment of these problems, contributing risk factors, potential complications, and therapeutic management approaches including manual maneuvers, positions, and when cesarean delivery may be recommended.
Intrapartum Care was developed for doctors and advanced midwives who care for women who deliver in district hospitals. It contains theory chapters and skills workshops adapted from the labour chapters of Maternal Care. Monitoring the mother, fetus, and progress of labour, the second and third stages of labour, managing pain, the puerperium and family planning
Placenta previa is a condition in which the placenta lies very low in the uterus and covers all or part of the cervix. The cervix is the opening to the uterus that sits at the top of the vagina. Placenta previa happens in about 1 in 200 pregnancies.
Placenta praevia risk factors include a previous delivery, age older than 35 and a history of previous surgeries, such as a caesarean section (C-section) or uterine fibroid removal.
The main symptom is bright red vaginal bleeding without pain during the second-half of pregnancy. The condition can also cause severe bleeding before or during delivery.
Limited physical activity is recommended. A C-section is often required in severe cases.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.

(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
Richard's aventures in two entangled wonderlandsRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.
2. PROLAPSE OF THE UMBILICAL
CORD/UMBILICAL CORD PROLAPSED
Main Problem:
* A loop of the umbilical cord slips down
in front of the presenting fetal part.
* Occurs at any time after the
membranes rupture if the presenting
part is not fitted firmly into the cervix.
* Incidence is 0.4% 0f births
3. PROLAPSE OF THE UMBILICAL CORD
A. The cord is prolapsed
but still within the
uterus.
B. The cord is visible at the
vulva.
4. PROLAPSE OF THE UMBILICAL
CORD/UMBILICAL CORD PROLAPSED
CONTRIBUTING FACTORS:
1. Premature rupture of membranes
2. Fetal presentation other than cephalic
3. Placenta previa
4. Intrauterine tumors preventing the presenting part
from engaging.
5. Small fetus
6. CPD preventing firm engagement
7. Hydramnios
8. Multiple gestation.
5. ASSESSMENT
1. Cord may be felt as presenting part on initial
vaginal exam.
- Inspect the perineum to confirm prolapse of the
cord before providing immediate intervention.
- Assess if the fetus is preterm or small for gestational
age; if the presenting part is not engaged, and it the
membranes are ruptured.
2. Cord may be visible at the vulva.
- If cord prolapse is identified, notify the physician
and prepare for emergency cesarean birth.
3. Sonogram
4. Variable deceleration FHR pattern
- Fetal bradycardia with deceleration during contraction
- Evaluation of FHR must be done periodically in 5-10
minutes, especially if the membranes are ruptured.
6. THERAPEUTIC MANAGEMENT
Complication: Fetal Distress or Fetal Hypoxia
/Anoxia d/t cord compression
Goal #1 : Relieve umbilical cord compression by relieving
pressure on the cord.
1. Place a gloved hand in the vagina and manually
elevating the fetal head off the cord.
2. Place the woman in a knee-chest or Trendelenburg
position.
3. Administer tocolytic agent as prescribed.
- To reduce uterine activity & pressure on the fetus.
7. THERAPEUTIC MANAGEMENT
Goal # 2: Improve oxygenation to the fetus
1. Administer oxygen at 10 L/min by face mask to the
mother.
Goal # 3: Prevent atrophy of the umbilical vessels.
(in case the umbilical cord prolapsed is
exposed to room air)
1. Cover the exposed portion of the cord with a sterile
saline compress to prevent drying.
2. Do not attempt to push any exposed cord back into
the vagina
- Pushing may add to the compression by causing
knotting or kinking.
8. THERAPEUTIC MANAGEMENT
Goal # 4: If cervix is fully dilated, prevent
fetal anoxia.
1. The physician may choose to deliver the infant
quickly (by forceps)
Goal # 5: If dilatation is incomplete, prevent
cord compression.
1. The birth method is upward pressure on the
presenting part in the woman’s vagina, to keep
pressure off the cord, and baby can be born by
C/S.
9. CRITICAL THINKING EXERCISE
NURSING MANAGEMENT OF THE CLIENT WITH A
PROLAPSED UMBILICAL CORD
Situation: A woman in labor room tells the nurse, “My water just
broke, and it felt like something fell out.”
1. Prioritize the following interventions for this client. Explain your
reasoning.
____ Place the woman in Trendelenburg position
____ Use a gloved hand to push the fetal presenting part upward
____ Administer oxygen
____ Call the primary care provider
____Press the call light for assistance
____ Inspect the perineum to see if the cord is visible
____ Assess the fetal heart rate
12. OCCIPITOPOSTERIOR POSITION
(ROP/LOP)
The fetal position is posterior rather than anterior,
the occiput is directed diagonally and posteriorly,
either to the right (ROP) or to the left (LOP).
Occiput
(LOP)
In these positions (LOP or ROP), during internal rotation, the fetal
head must rotate through an arc of 135°
15. ASSESSMENT
1. Dysfunctional labor pattern AEB a prolonged active
phase, arrested descent.
2. Fetal heart sounds heard best at the lateral sides of
the abdomen.
3. The fetal presenting head does not snugly fit the
cervix.
4. The position of the fetus is confirmed by sonogram
5. Prolonged labor because the arc of rotation is
greater.
6. Woman experience intense lower back
pressure & pain due to sacral nerve
compression.
16. THERAPEUTIC MANAGEMENT:
1. Counterpressure on the sacrum (e.g. back rub)
Relieve a portion of pain
2. Applying heat or cold
3. Assist woman on side-lying
position opposite the fetal back or maintaining a hands-and-
knees position.
4. Let woman void every 2 hrs. to keep bladder empty
Full bladder could further impede descent of the fetus
5.During long labor, IV glucose solution to replace glucose stores
used for energy.
17. THERAPEUTIC MANAGEMENT:
6. Fetus may be born by C/S if:
Contractions are ineffective
Fetus larger than average
Fetus not in good flexion
Fetal head may arrest in the transverse
position.
Persistent occipitoposterior position
7. Provide emotional support.
18. BREECH PRESENTATION
- Either the buttocks or the feet are the first body
parts that will contact the cervix.
- 3% of births are breech presentations; can be
difficult births with the presenting point influencing
the degree of difficulty.
- 3 Types:
1. Complete
2. Frank
3. Footling
19. BREECH PRESENTATION
1. Frank breech presentation
Lie: Longitudinal
Attitude: Moderate
1
• Attitude is moderate because the hips are flexed but the knees are
extended to rest on the chest. The buttocks alone present to the
cervix.
20. BREECH PRESENTATION
2. Complete breech presentation
Lie: Longitudinal
Attitude: Good (fulLflexion)
2
• The fetus has thighs tightly flexed on the abdomen; both the
buttocks and the tightly flexed feet present to the cervix.
21. BREECH PRESENTATION
3. Footling breech presentation
Lie: Longitudinal
Attitude: Poor
3
• Neither the thighs nor lower legs are flexed. If one foot presents, it
is a single-footling breech; if both present, it is a double-footling
breech.
22. BREECH PRESENTATION
Complications:
1. Anoxia from prolapsed cord
2. Traumatic injury to the after-coming head
(possibility of intracranial haemorrhage or
anoxia)
3. Fracture of the spine or arm
4. Dysfunctional labor
5. Early rupture of the membranes because of
the poor fit of the presenting part.
6. Meconium aspiration
23. BREECH PRESENTATION
Assessment:
1. FHT heard high in the abdomen
2. Leopold’s, vaginal exam, or ultrasound exam
reveals the presentation.
- Ultrasound clearly confirms the presentation including
additional information on pelvic diameters, fetal skull
diameter, and evidence of possible placenta previa causing
the breech presentation.
3. Monitor FHR and uterine contractions
continuously
- to detect early signs of fetal distress from a complication like
prolapsed cord.
24. BREECH PRESENTATION
- Birth technique:
1. Vaginal delivery
Birth of head is the most hazardous because
umbilicus precedes the head.
Head compresses the cord
2nd danger is intracranial hemorrhage
2. Planned C/S – usual method
25. BREECH PRESENTATION
BIRTH TECHNIQUE: VAGINAL DELIVERY
As the breech spontaneously
emerges from the birth canal, it
is steadied and supported by a
sterile towel against the infant’s
inferior surface.
To aid in delivery of the head, the
trunk of the infant is usually
straddled over the physician’s right
forearm .
Two fingers of the physician’s left
hand are placed in the infant’s
mouth
27. Vertex Malpresentation
Face presentation (chin, or mentum)
o Fetus is in poor flexion
o Back is arched
o Neck extended
o Complete extension
o Presenting the occipitomental diameter (13.5 cm)
FACE
28. VERTEX MALPRESENTATION:
FACE PRESENTATION
ASSESSMENT
CONTRIBUTING FACTORS:
1. Woman with contracted pelvis
2. Placenta previa
3. Relaxed uterus of a multipara
4. Prematurity, hydramnios, or fetal malformation
A sonogram is done to confirm
- If the chin is anterior and the pelvic diameters are within
normal limits, a successful vaginal birth is possible.
- If the chin is posterior, cesarean birth may be the method of
choice to avoid uterine dysfunction or a transverse arrest.
29. VERTEX MALPRESENTATION:
FACE PRESENTATION
Therapeutic management:
1. Observe infant for patent airway
May have a great deal of facial edema and
may be purple from ecchymotic bruising.
2. Gavage feeding
Lip edema is so severe that the infant is
unable to suck for a day or 2.
3. Observe infant for 24 hours in ICU nursery.
30. VERTEX MALPRESENTATION:
BROW PRESENTATION
It is the rarest of the presentations. BROW
CONTRIBUTING FACTOR:
1. Multipara or a woman with relaxed abdominal muscles.
ASSESSMENT:
1. Obstructed labor
BIRTH TECHNIQUE:
1. Cesarean birth
31. VERTEX MALPRESENTATION:
BROW PRESENTATION
Therapeutic management:

- May have extreme ecchymotic bruising on the face, over the
same area as the anterior fontanelle or “soft spot”.
2. Infant must be observe for eye injury.
32. TRANSVERSE LIE
Description:
- A fetus lies horizontally in the pelvis, longest fetal
axis is perpendicular to that of the mother.
- The presenting part is one of the shoulders
(acromion process), an iliac crest, a hand, or an
elbow
33. TRANSVERSE LIE
Occurs in women with:
1. Women with pendulous abdomen
2. Uterine masses that obstructs the lower uterine
segment

2. Confirmed by Leopold’s maneuver
3. Ultrasound
Complications:
1. Early rupture of membranes usually at the beginning of
labor.
2. Cord or arm prolapse or shoulder may obstruct the cervix
Therapeutic management:
1. C/S is the birth method of choice
35. OVERSIZED FETUS
(MACROSOMIA)
Fetus who weighs more than 4,000 – 4,500 g
(9 – 10 lbs.)
Risk factors:
1. Diabetic or develop gestational diabetes
2. Multiparity
36. OVERSIZED FETUS
(MACROSOMIA)
Complications:
1. Uterine dysfunction during labor/birth
• Overstretching of the fibers of the myometrium
2. Wide shoulders cause fetal pelvic disproportion
3. Uterine rupture from obstruction
4. Fractured clavicle of the baby because of
shoulder dystocia
5. Woman has an increased risk of hemorrhage
• Overdistended uterus may not contract

38. FETAL DISTRESS
ASSESSMENT FINDINGS TRIAD SYMPTOMS
1. FHT above 160 or below 120 per minute
2. Meconium-stained amniotic fluid in a non-breech
presentation
3. Fetal hypermobility/hyperactivity
39. FETAL DISTRESS
NURSING IMPLEMENTATION
1. Reposition mother to left lateral recumbent (LLR).
- To relieve pressure on the inferior vena cava (IVC) , thereby increasing
venous return resulting in increased perfusion of placenta and fetus.
2. Stop the oxytocin drip if being infused.
3. Administer oxygen per mask at 6-7 liters per minute.
4. Correct hypotension.
a. Elevate legs
b. Increase IV rate (increase hydration) provided the IV fluid is plain and
with no oxytocin.
c. Turn mother to her left if it is a case of vena caval syndrome.
5. Monitor FHT continuously.
6. Notify the physician.
7. Prepare for emergency CS if indicated
