Labor consists of a series of rhythmic, involuntary or medically induced contractions of the uterus that result in effacement (thinning and shortening) and dilation of the uterine cervix. The World Health Organization (WHO) defines normal birth as follows:
The birth is spontaneous in onset and low risk at the start of labor and remains so throughout labor and delivery.
The infant is born spontaneously in the vertex position between 37 and 42 weeks of pregnancy.
After birth, mother and infant are in good condition (1).
The stimulus for labor is unknown, but digitally manipulating or mechanically stretching the cervix during examination enhances uterine contractile activity, most likely by stimulating release of oxytocin by the posterior pituitary gland.
Normal labor usually begins within 2 weeks (before or after) the estimated delivery date. In a first pregnancy, labor usually lasts 12 to 18 hours on average; subsequent labors are often shorter, averaging 6 to 8 hours.
Labor begins with irregular uterine contractions of varying intensity; they apparently soften (ripen) the cervix, which begins to efface and dilate. As labor progresses, contractions increase in duration, intensity, and frequency.
Stages of labor
There are 3 stages of labor.
The 1st stage—from onset of labor to full dilation of the cervix (about 10 cm)—has 2 phases, latent and active.
During the latent phase, irregular contractions become progressively coordinated, discomfort is minimal, and the cervix effaces and dilates to 4 cm. The latent phase is difficult to time precisely, and duration varies, averaging 8 hours in nulliparas and 5 hours in multiparas; duration is considered abnormal if it lasts > 20 hours in nulliparas or > 12 hours in multiparas.
During the active phase, the cervix becomes fully dilated, and the presenting part descends well into the midpelvis. On average, the active phase lasts 5 to 7 hours in nulliparas and 2 to 4 hours in multiparas. Traditionally, the cervix was expected to dilate about 1.2 cm/hour in nulliparas and 1.5 cm/hour in multiparas. However, recent data suggest that slower progression of cervical dilation from 4 to 6 cm may be normal (1). Pelvic examinations are done every 2 to 3 hours to evaluate labor progress. Lack of progress in dilation and descent of the presenting part may indicate dystocia (fetopelvic disproportion).
Standing and walking shorten the first stage of labor by > 1 hour and reduce the rate of cesarean delivery
The placenta is said to be retained when it is not expelled from the uterus even 30 minutes after the delivery of the baby
Manual placenta removal is a procedure to remove a retained placenta from the uterus after childbirth.

Physiological changes in second stage of laborDR MUKESH SAH
There is an interplay of physiological processes occurring during the second stage of labour. Second stage is said to have two phases, latent and active. It is during the latent phase that the presenting part passes through the fully dilated cervix to the birth canal.
The second stage of labor begins when the cervix is completely dilated (open), and ends with the birth of your baby. Contractions push the baby down the birth canal, and you may feel intense pressure, similar to an urge to have a bowel movement. Your health care provider may ask you to push with each contraction.

Dive into the world of nursing research with our comprehensive presentation on various types of research designs. This informative PPT delves into the intricacies of quantitative, qualitative, and mixed-methods research, highlighting their unique designs, applications, and implications in the nursing field. Understand the strengths and weaknesses of each approach and gain insights into how they contribute to evidence-based nursing practices. Whether you're a seasoned nurse or a nursing student, this presentation will provide valuable insights to enhance your research knowledge.
Comprehensive exploration of the diverse landscape of research designs within the nursing field. This presentation serves as a valuable resource for nurses, healthcare professionals, and students keen on understanding the nuances of various research methodologies and their impact on evidence-based nursing practices. With a focus on types of research designs, their advantages, and disadvantages, this presentation offers an in-depth journey into the world of nursing research.
In the dynamic realm of healthcare, research plays a pivotal role in shaping clinical practices and enhancing patient outcomes. This presentation begins by elucidating the fundamental categories of research designs: quantitative, qualitative, and mixed-methods. Each design is dissected to provide a clear understanding of its core principles, methodologies, and applications in nursing contexts.
Quantitative research, known for its structured and numerical approach, is explored with a spotlight on its ability to yield statistically significant results. The presentation delves into the process of hypothesis formulation, data collection through surveys or experiments, and the subsequent analysis methods. However, the presentation also acknowledges the challenges of quantitative research, such as potential bias and limited exploration of complex phenomena.
In contrast, qualitative research is presented as a qualitative exploration of experiences, beliefs, and motivations. The presentation explains the various techniques for data collection, including interviews, focus groups, and observations. It underscores the value of capturing rich, contextual insights that quantitative methods might overlook. Yet, qualitative research is not without its limitations, including potential subjectivity and difficulty in generalizing findings.
To bridge the gap between these two approaches, the presentation introduces mixed-methods research as a harmonious fusion of quantitative and qualitative methodologies. This section outlines the benefits of triangulating data, providing a more comprehensive understanding of research questions. However, it also acknowledges the challenges of managing the intricacies of both approaches within a single study.

Simulation has been used widely in the clinical training of health-care students and
professionals. It is a valuable strategy for teaching, learning and evaluating clinical skills
at different levels of nursing and midwifery education: undergraduate, postgraduate and
lifelong education (Park et al., 2016; Martins, 2017).
Simulation has a positive impact on students, educators, and the individuals, groups
and communities they care for, as well as on education and health organizations. The
principal aims of simulation as a teaching method are to improve quality of care and
ensure patient safety.
The WHO document Transforming and scaling up health professionals’ education and training (WHO,
2013) strongly recommends the use of simulation. Recommendation 5 states:
Health professionals’ education and training institutions should use simulation methods
(high fidelity methods in settings with appropriate resources and lower fidelity methods in
resource limited settings) of contextually appropriate fidelity levels in the education of health
professionals.
A large proportion of nursing and midwifery education curricula worldwide is dedicated
to the acquisition of clinical skills. At the beginning of the learning period in clinical
settings, students should be able to develop safe and timely evidence-based interventions
without being interrupted by supervisors due to technical errors that may jeopardize
patients’ and students’ safety. In clinical practice with actual patients, students should
be self-confident and feel that others trust them; they should feel capable of performing
tasks without errors and be confident that the supervisor and other team members
believe in their abilities.
From an ethical perspective, invasive procedures should not be taught or practised on
real people; instead, trainees should be able to train in simulated, controlled and safe
environments, allowing them to make errors and learn from them with no harmful
consequences to any person. This ensures absolute respect for human rights by protecting
patients’ dignity and guarantees the quality of nursing care, even during health
professionals’ learning processes.

The common thread uniting different types of nurses who work in varied areas is the nursing process—the essential core of practice for the registered nurse to deliver holistic, patient-focused care
One of the most important tools a nurse can use in practice is the nursing process. Although nursing schools teach first-year students about the nursing process, some nurses fail to grasp the impact its proper use can have on patient care. In this article, I will share information about the nursing process, its history, its purpose, its main characteristics, and the 5 steps involved in carrying out the nursing process.
• Establishes plans to meet patient needs
• Guides nurses in the delivery of high-quality evidence-based care
• Protects nurses against potential legal problems
• Promotes a systematic approach to patient care that all members of the nursing team can follow
The nursing process consists of five steps which encompass the care provided. The five nursing process steps are:
1. Assessment
2. Diagnosis
3. Planning
4. Implementation
5. Evaluation

Pressure ulcers (also known as pressure sores or bedsores) are injuries to the skin and underlying tissue, primarily caused by prolonged pressure on the skin. They can happen to anyone, but usually affect people confined to bed or who sit in a chair or wheelchair for long periods of time.
t is widely believed that other factors can influence the tolerance of skin for pressure and shear, thereby increasing the risk of pressure ulcer development. These factors are protein-calorie malnutrition, microclimate (skin wetness caused by sweating or incontinence), diseases that reduce blood flow to the skin, such as arteriosclerosis, or diseases that reduce the sensation in the skin, such as paralysis or neuropathy. The healing of pressure ulcers may be slowed by the age of the person, medical conditions (such as arteriosclerosis, diabetes or infection), smoking or medications such as anti-inflammatory drugs.

Labour is rhythmic contraction and relaxation of the
uterine muscles with progressive effacement i.e thinning
and dilatation i.e. opening of the cervix, leading to
expulsion of the products of conception.
DEFINITION
NILOFAR LOLADIYA
3. D.C DUTTA
A series of events that take place in the genital organs
in an effort to expel the viable products of conception
out of the womb into vagina into the outer world is
called labour.
DEFINITION
NILOFAR LOLADIYA
7. FIRST STAGE:
• It is that of dilatation of cervix.
• Begins with regular rhythmic contraction
and is complete when cervix is fully
dilated and effaced.
• In other words it is the cervical stage.
• Primigravida- 12 hours
• Multipara- 6 hours
NILOFAR LOLADIYA
12. Too much Fibrosis as in chronic cervicitis, prolapse or
organic lesion in the cervix as in carcinoma results in
deficiency of these factors. As a result cervix may fail to
dilate.
NILOFAR LOLADIYA
13. A. Uterine Contraction and retraction.
B. Formation of Bag of membranes.
C. Fetal axis pressure.
D. Vis-a-tergo.
1. DILATATION
2. EFFACEMENT
3.FORMATION OF LOWER UTERINE SEGMENT
EVENTS IN FIRST STAGE OF LABOUR
NILOFAR LOLADIYA
14. • The longitudinal muscle fibres of the upper segment are attached with
circular muscle fibres of the lower segment and upper part of the cervix in
the bucket holding fashion.
• Thus, with each uterine contraction not only the canal is opened up from
above down but it also becomes shortened and retracted.
• Upper segment contract, retracts and pushes the foetus,
• The lower segment and cervix dilate in response to the forces of contraction
of upper segment.
A. Uterine Contraction and retraction
NILOFAR LOLADIYA
16. B. Formation of Bag of membranes.
-
• During labour the membranes attached to the lower uterine segment are
detachted
-
• Herniation of membranes through the cervical canal
-
• BALL-VALVE Action of well flexed head,
• During Uterine contraction, hydrostatic pressure in forewaters increases
Cervical dilatation NILOFAR LOLADIYA
18. C. Fetal axis pressure.
In longitudinal lie, there is tendency of straightening out of the fetal
vertebral column due to contraction.
This allows the fundal contraction to transmit.
Allows mechanical stretching of the lower segment and opening of the
cervical Canal.
With each uterine contraction, there is elongation of the uterine ovoid and
decrease in the transverse diameter.
Absent in transverse lie.
NILOFAR LOLADIYA
19. D. Vis-a-tergo.
The final phase of dilatation and retraction of the cervix.
There is downward thrust of the presenting part of the fetus and
upward pull of the cervix over the lower segment.
Absent in transverse lie.
NILOFAR LOLADIYA
20. Effacement is the process by which the muscular fibres of the
cervix are pulled upwards and merges with the fibres of the lower
uterine segment.
Shortening of cervical Canal from its usual length of 2 to 3
centimetres to one in which the cervical Canal is obliterated
leaving only the external os as a circular orifice with thin edges.
NILOFAR LOLADIYA
2. EFFACEMENT or ‘taking up’ of the Cervix.
23. Expulsion of mucus plug is caused by effacement.
The cervix becomes thin during first stage of labour or even
before that in primigravida.
In primigravida effacement proceed dilatation of the cervix,
where as in multipara both occur simultaneously.
NILOFAR LOLADIYA
25. 3.FORMATION OF LOWER UTERINE SEGMENT
Before the onset of labour there is no complete Anatomical or functional
division of the uterus.
During labour, the demarcation of an active upper segment and a relatively
passive lower segment..
The wall of the upper segment becomes progressively thickened with
progressive thinning of the lower segment.
More pronounced in late first stage, especially after rupture of membranes.
NILOFAR LOLADIYA
28. ANATOMICAL FEATURES:
Developed from Isthmus.
Above: Physiological ring.
Below: Fibromuscular junction
of cervix and uterus.
7.5-10 cm when fully formed.
Gradually becomes thin.
NILOFAR LOLADIYA
29. CLINICAL SIGNIFICANCE:
Enables expulsion of fetus.
Caesarean section is performed at this segment.
Poor decidual reaction facilitates morbid adherent placenta.
In obstructed labour, it gets stretched and thinned and ultimately
ruptures.
Passive segment, Poor retractile property
Chances of PPH if placenta implanted here.
NILOFAR LOLADIYA
31. SECOND STAGE:
• It is the stage of expansion of the
foetus it begins with complete
dilation of the cervix through
complete birth of a baby.
• Primigravida- 2 hours
• Multipara- 30 mins
NILOFAR LOLADIYA
32. The second stage begins with the complete dilatation of the cervix
and ends with the expulsion of the fetus.
It is concerned with the descent and delivery of the fetus through
the birth canal.
A. Propulsive Phase:
Full Dilatation-head touches the pelvic floor
B. Expulsive Phase:
Irresistible desire to ‘bear down’ and push until the baby is
delivered.

34. DEFINITION: MECHANISM OF LABOUR
The series of movements that occur on the head in the
process of adaptation, during its journey through the pelvis, is
called mechanism of labour.
NILOFAR LOLADIYA
35. PRINCIPLES:
Descent takes place throughout the labour.
Whichever part leads and first meets the resistance of the
pelvis floor will rotate forward until it comes under the
symphysis pubis.
Whatever emerges from the pelvis will pivot around the pubic
bone.

NILOFAR LOLADIYA
MECHANISM OF LABOUR
38. 1. ENGAGEMENT:
The head enters the brim of the pelvis and gets fixed.
2. DESCENT:
Slow progressive throughout the labour
Factors responsible are-
• Uterine contractions and retractions
• Bearing down efforts
• Straightening of fetal ovoid specially after rupture of membranes
NILOFAR LOLADIYA
39. 3. FLEXION OF HEAD:
• Flexion is achieved either due to the resistance offered by the unfolding cervix, the
walls of the pelvis or by the pelvic floor. Essential for descent, since it reduces the
shape and size of the plane of the advancing diameter of the head.
• Sagittal Suture over Rt Oblique diameter
• Shoulder over Lt Oblique diameter
NILOFAR LOLADIYA
Subocciputo Frontal
(10 cm)
Subocciputo Bregmatic
(9.5cm)
40. 4. INTERNAL ROTATION OF HEAD:
• Occiput leads and meets the pelvic floor first and rotate anteriorly through 1/8th of
a circle
• From Lt Iliopectineal eminence to the symphysis pubis
• Causes a slight twist in the neck of the fetus
• Thus, head no longer in direct alignment with the shoulder
NILOFAR LOLADIYA
41. 5. CROWNING:
• The occiput slips beneath the sub-pubic arch
• crowning occurs when the head is no longer
• recedes in between the contractions .
• Occiputal eminence escapes under symphysis pubis.
6. EXTENSION OF THE HEAD:
Fetal head extends the nape of the neck/
subocciputal region pivots on the
lower border of the symphysis pubis.
Sinciput, face and chin:
sweeps the perineum
• Head is born by extension
NILOFAR LOLADIYA
42. 7. RESTITUTION:
Turning of the head to undo the twist in the neck
TWIST- Neck of the fetus which resulted from internal rotation is now corrected
by slight untwisting movement.
Occiput moves 1/8th of a circle towards left i.e. the side from it started
8. INTERNAL ROTATION OF SHOULDER
From Lt oblique to AP diameter
Anterior shoulder reaches the Rt side of the pelvic floor
Rotates forward bringing shoulder into the AP diameter of outlet
EXTERNAL ROTATION OF HEAD: Occiput-further 1/8th circle the same direction
as restitution
Occiput lies laterally, faces the opposite thigh
NILOFAR LOLADIYA
43. 9. LATERAL FLEXION:
Anterior shoulder-first, Slips beneath the
subpubic arch
Posterior- passes over the perineum
BIRTH OF SHOULDER AND TRUNK:
Remaining by lateral flexion
Spine bends sideways through the curved
canal
NILOFAR LOLADIYA
Anterior shoulder
Posterior shoulder
44. MANAGEMENT OF THE SECOND STAGE
The transition from the first stage to the second stage is
evidenced by the following features:
Increasing intensity of uterine contractions.
Appearance of bearing down efforts.
Urge to defecate with descent of the presenting part.
Complete dilatation of the cervix as evidenced on vaginal
examination
NILOFAR LOLADIYA
45. PRINCIPLES:
(1)To assist in the natural expulsion of the fetus slowly and steadily,
(2)To prevent perineal injuries.
GENERAL MEASURES:
— The patient should be in bed.
— Constant supervision is mandatory and the FHR is recorded at every 5 minutes.
— To administer inhalation analgesics, if available, in the form of Gas N2O and O2
to relieve pain during contractions.
— Vaginal examination is done at the beginning of the second stage not only to
confirm its onset but to detect any accidental cord prolapse.
The position and the station of the head are once more to be reviewed and the
progressive descent of the head is ensured
NILOFAR LOLADIYA
46. PREPARATION FOR DELIVERY
— Position: Positions of the woman during delivery may be lateral
or partial sitting. Dorsal position with 15° left lateral tilt is
commonly favored as it avoids aortocaval compression and
facilitates pushing effort.
—Scrubs up and puts on sterile gown, mask and gloves and stands
on the right side of the table.
— Toileting the external genitalia and inner side of the thighs is
done with cotton swabs soaked in Savlon or Dettol solution.
NILOFAR LOLADIYA
47. One sterile sheet is placed beneath the buttocks of the
patient and one over the abdomen. Sterilized leggings
are to be used.
Essential aseptic procedures are remembered as 3 ‘C’s:
(a)Clean hands,
(b)Clean surface and
(c)Clean cutting and ligaturing of the cord.
— To catheterize the bladder, if it is full.
NILOFAR LOLADIYA
49. Perineal lacerations:
1st = involving skin or vaginal mucosa BUT NOT into muscle
2nd = extending from skin & vaginal mucosa into m
muscles of perineum
3rd = extending from skin, vaginal muscosa into the anal
sphincter
4th = extending through the rectal mucosa into the lumen of
the rectum NILOFAR LOLADIYA
72. THIRD STAGE:
• Third stage of labour begins after
expulsion of the fetus and ends with
expulsion of the placenta and
membranes (after-births).
• Duration: 15 minutes in both
primigravidae and multiparae.
• Active management: 5Minutes

about its half.
As the placenta is inelastic, it cannot keep pace with such an extent of diminution
resulting in its buckling.
A shearing force is instituted between the placenta and the placental site
Placental Separation
76. • Detachment of the placenta from its uterine
attachment starts at the centre
• Resulting in opening up of few uterine
sinuses
• Accumulation of blood behind the placenta
(retroplacental haematoma).
• More and more detachment occurs
facilitated by weight of the placenta and
retroplacental blood until whole of the
placenta gets detached.

Central separation (Schultze):
77. • Separation starts at the margin as it is
mostly unsupported.
• With progressive uterine contraction, more
and more areas of the placenta get
separated.
• Marginal separation is found more
frequently.

Marginal separation (Mathews-Duncan):
78. • Membranes attached to the lower segment are already separated
during its stretching.
• The separation is facilitated partly by uterine contraction and mostly by
weight of the placenta as it descends down from the active part.

Descent into the lower segment
79. Expulsion of placenta
• After complete separation of the placenta, it is forced
down into the flabby lower uterine segment or upper
part of the vagina by effective contraction and
retraction of the uterus.
• Thereafter, it is expelled out by either voluntary
contraction of abdominal muscles (bearing down
efforts) or by manual procedure.

80. • Expulsion of placenta and membranes:-
• The expulsion is achieved either by voluntary bearing
down efforts or more commonly aided by manipulative
procedure.
• The “after-birth” delivery is soon followed by slight to
moderate bleeding amounting to 100-250 ml.
• Maternal signs:- There may be chills and occasional
shivering. Slight transient hypotension is not unusual.

81. Assisted expulsion:
• (A) Controlled cord traction
(modified Brandt – Andrews
method) –
• The palmar surface of the
fingers of the left hand is
placed (above the symphysis
pubis) approximately at the
junction of upper and lower
uterine segment.

82. Assisted expulsion:
(A) Controlled cord traction
The body of the uterus is pushed
upwards and backwards, towards
the umbilicus while by the right
hand steady tension is given in
downward and backward direction
holding the clamp until the placenta
comes outside the introitus.
NILOFAR LOLADIYA
83. Assisted expulsion:
(A) Controlled cord traction
• It is thus more an uterine
elevation which facilitates
expulsion of the placenta.
The procedure is to be
adopted only when the
uterus is hard and
contracted.

84. • (b) Fundal pressure –
• The fundus is pushed downwards and
backwards after placing four fingers
behind the fundus and the thumb in
front using the uterus as a sort of
piston.
• The pressure must be given only when
the uterus becomes hard. If it is not,
then make it hard by gentle rubbing.
The pressure is to be withdrawn as
soon as the placenta passes through
the introitus. .
NILOFAR LOLADIYA
85. • (b) Fundal pressure –
• If the baby is macerated or premature, this method is
preferable to cord traction as the tensile strength of the
cord is much reduced in both instances.
• The cord may be accidentally torn which is not likely to
cause any problem. The sterile gloved hand should be
introduced and the placenta is to be grasped and
extracted.
NILOFAR LOLADIYA
86. Mechanism of control of bleeding
• After placental separation, innumerable torn sinuses
which have free circulation of blood from uterine and
ovarian vessels have to be obliterated.
• The occlusion is effected by complete retraction whereby
the arterioles, as they pass tortuously through the
interlacing immediate layer of the myometrium, are
literally clamped.
• It (living ligature) is the principle mechanism of
haemostasis.

89. • Oxytocic drugs for active management of third stage of
labour:-
• Commonly used drugs are,
• Oxytocin
• Ergot alkaloids (ergometrine/methyl ergometrine)
• Misoprostol
• Carboprost (15-methyl PGF2 )
• Researches suggest that oxytocin is the agent of choice for
active management of third stage of labour.

90. Nursing Management
Nursing Priorities:-
1.Promote uterine
contractility
2.Maintain circulating
fluid volume
3.Promote maternal and
newborn safety
4.Support parent-infant
interaction
NILOFAR LOLADIYA
Nursing assessment:
Blood pressure and pulse rate
Amount of blood loss
Leg cramps/body tremors
Uterine contractions
Shape and level of fundus
Signs of placental separation
Extent of perineal laceration/episiotomy
Completeness of placenta and membranes
91. WHO recommendations for optimal timing of cord clamping for
the prevention of iron deficiency anaemia in infants
• WHO guidelines on basic newborn resuscitation:
• In newly born term or preterm babies who do not require
positive-pressure ventilation, the cord should not be
clamped earlier than 1 min after birth.
• When newly born term or preterm babies require positive-
pressure ventilation, the cord should be clamped and cut
to allow effective ventilation to be performed.
NILOFAR LOLADIYA
92. • Newly born babies who do not breathe spontaneously after
thorough drying should be stimulated by rubbing the back 2–3
times before clamping the cord and initiating positive-pressure
ventilation.
• WHO recommendations for the prevention and treatment of
postpartum haemorrhage
• Late cord clamping (performed approximately 1–3 min after
birth) is recommended for all births, while initiating
simultaneous essential neonatal care.
• Early umbilical cord clamping (less than 1 min after birth) is not
recommended unless the neonate is asphyxiated and needs to
be moved immediately for resuscitation.
