IVF (In Vitro Fertilization)

Definition
IVF is an assisted reproductive technology (ART) in which an egg is fertilized with s***m outside the body in a laboratory, and the resulting embryo is transferred into the uterus.

Indications
Blocked or damaged fallopian tubes
Male-factor infertility
Ovulation disorders
Endometriosis
Unexplained infertility
Age-related infertility
Selected genetic conditions when PGT is indicated

IVF Procedure — Steps

Ovarian Stimulation
Fertility medicines stimulate development of multiple follicles

Monitoring & Trigger
Ultrasound and hormone tests monitor follicular development.
A trigger medicine is given before egg retrieval.

Oocyte Retrieval
Mature eggs are collected, usually using transvaginal ultrasound-guided aspiration.

Fertilization
Eggs are fertilized with s***m using conventional IVF or ICSI when indicated.

Embryo Culture
Fertilized eggs develop in the laboratory for several days.

Embryo Transfer
Selected embryo(s) are transferred into the uterus using a thin catheter.

Luteal Phase Support
Progesterone is commonly prescribed to support the endometrium.

Pregnancy Test
Serum β-hCG testing is usually performed around 9–14 days after embryo transfer, depending on clinic protocol.

Factors Affecting IVF Success
Maternal age
Ovarian reserve
Cause of infertility
S***m quality
Embryo quality
Uterine/endometrial factors
Previous reproductive history
Lifestyle factors

Types of Appendicitis

Catarrhal (Simple) Appendicitis
Early stage of acute appendicitis.
Mucosal inflammation with edema and congestion.

Suppurative (Phlegmonous) Appendicitis
More advanced inflammation with neutrophilic infiltration.
Pus may be present within the wall and lumen.

Gangrenous Appendicitis
Reduced blood supply causes ischemia and necrosis of the appendiceal wall.
Appendix may appear dark or gangrenous.

Perforated Appendicitis
The inflamed appendix ruptures or develops a perforation.
Intestinal contents can leak into the peritoneal cavity.
May cause localized or generalized peritonitis.

Periappendicitis
Inflammation mainly involves tissues/serosa around the appendix.
Often occurs secondary to nearby inflammatory disease.

Appendicular Abscess
Localized collection of pus around a perforated or severely inflamed appendix.
May be surrounded by bowel loops and omentum.

Chronic/Recurrent Appendicitis
Rare and less clearly defined than acute appendicitis.
Recurrent or persistent symptoms may occur with chronic inflammatory/fibrotic changes.

Quick progression to remember:
Simple → Suppurative → Gangrenous → Perforation → Abscess/Peritonitis

For a nursing infographic, the first 4 acute pathological stages are the most useful to emphasize.

Types of Tissues

Tissue: A group of similar cells that work together to perform a specific function.

1. Epithelial Tissue
Functions
Covers body surfaces
Lines body cavities and organs
Protection
Secretion
Absorption
Examples: Epidermis of skin, lining of mouth and GI tract, kidney tubules, glands.

2. Connective Tissue
Functions
Binds and supports tissues
Protection and cushioning
Transport
Energy storage
Insulation
Examples: Bone, cartilage, blood, adipose tissue, tendons, ligaments and areolar tissue.

3. Muscular Tissue
Functions
Produces movement
Maintains posture
Stabilizes joints
Generates heat
Moves substances through organs
Three Types
Skeletal muscle — voluntary movement
Smooth muscle — involuntary; found in walls of hollow organs
Cardiac muscle — involuntary; forms the myocardium of the heart

4. Nervous Tissue
Functions
Detects internal and external changes
Generates and transmits electrical signals
Processes information
Helps coordinate body functions
Main cells
Neurons — conduct signals
Neuroglia (glial cells) — support, protect and maintain neurons

🧠 Quick Memory
E – C – M – N
Epithelial → Cover
Connective → Connect & support
Muscular → Movement
Nervous → Communication

⭐ Remember: The human body has four basic tissue types: epithelial, connective, muscle and nervous tissue.

🍼 5 Types of Breast Milk
Colostrum — First milk; yellowish, protein- and antibody-rich.
Transitional milk — Transition between colostrum and mature milk.
Mature milk — Established milk that provides the infant's ongoing nutrition.
Foremilk — Milk at the beginning of a feed; generally lower in fat than milk later in the feed.
Hindmilk — Milk later in the feed; generally higher in fat and energy.

Ventilator Basics

Definition
A mechanical ventilator is a machine that supports or replaces spontaneous breathing by delivering oxygen and positive-pressure breaths to a patient.

Common Indications
Acute respiratory failure
Severe hypoxemia
Hypercapnic respiratory failure
Apnea or respiratory arrest
Inability to protect the airway
Severe ARDS
Reduced level of consciousness with inadequate ventilation
Selected postoperative or critical-care patients

Main Parts
Display/monitor: Shows settings, measured values, waveforms and alarms
Controls: Used to set ventilator parameters
Breathing circuit: Connects the ventilator to the patient
Humidification system: Provides heated/moisturized inspired gas when required

Common Ventilator Modes

A/C — Assist-Control
Provides a set minimum respiratory rate.
Patient-triggered breaths can also receive the preset support.

SIMV — Synchronized Intermittent Mandatory Ventilation
Provides a set number of synchronized mandatory breaths.
Allows spontaneous breathing between mandatory breaths.

CPAP — Continuous Positive Airway Pressure
Patient breathes spontaneously.
Continuous positive airway pressure is maintained throughout the respiratory cycle.

Important Ventilator Parameters
TV/VT – Tidal Volume: Volume delivered with each breath. Lung-protective ventilation commonly uses about 6–8 mL/kg predicted body weight, with lower VT often used in ARDS.

RR – Respiratory Rate: Number of mandatory breaths/min; individualized to ventilation needs.
FiO₂: Fraction of inspired oxygen, 21–100%; titrate to the patient's oxygenation target.

PEEP: Positive pressure remaining at end-expiration; commonly starts around 5 cmH₂O but is individualized.

Trigger sensitivity: Determines how much patient effort is required to trigger an assisted breath.

Ventilator Waveforms

Monitor:
Pressure–time
Flow–time
Volume–time

Waveforms can help identify:
Patient–ventilator asynchrony
Air leaks
Air trapping/auto-PEEP
Changes in airway resistance or compliance

Possible Complications
Ventilator-associated pneumonia/events
Barotrauma or pneumothorax
Volutrauma
Atelectasis
Oxygen toxicity with prolonged high FiO₂
Hemodynamic compromise from positive pressure
Patient–ventilator asynchrony
Airway/laryngeal injury

Nursing Responsibilities
Assess the patient first, not just the ventilator.
Monitor vital signs, SpO₂, respiratory status and ABGs as indicated.
Check prescribed ventilator settings and alarms.
Assess chest movement and breath sounds.
Ensure airway and endotracheal/tracheostomy tube security and patency.
Provide oral care and VAP-prevention measures according to local protocol.
Maintain appropriate humidification.
Position appropriately; head-of-bed elevation is commonly used when not contraindicated.
Assess pain, comfort and sedation needs.
Document observations and report deterioration promptly.

🚨 Important Safety Point
If a ventilated patient suddenly deteriorates, assess the patient and airway immediately. Call for help and use manual ventilation with oxygen if clinically required while the cause is investigated.

Memory aid: TRAP T – Tidal Volume
R – Respiratory Rate
A – Airway pressure/PEEP
P – Percentage of oxygen (FiO₂)

Definition
An episiotomy is a surgical incision made in the perineum during the second stage of labour to enlarge the vaginal opening when clinically indicated and facilitate birth.

Types
Mediolateral episiotomy
Midline/median episiotomy

Goals of Care
Promote wound healing
Relieve pain and discomfort
Prevent infection
Detect complications early
Promote comfort and mobility

Assessment
Check vital signs and overall postpartum condition
Inspect the wound using REEDA:
Redness
Edema
Ecchymosis
Discharge
Approximation
Assess pain
Check for hematoma and excessive bleeding
Assess lochia
Monitor bladder and bowel function

Episiotomy Care
1. Perineal hygiene
Wash with clean/warm water after urination or bowel movements.
Clean/wipe front to back.
2. Keep clean and dry
Change maternity/perineal pads regularly.
Perform hand hygiene before and after perineal care.
3. Cold therapy
A wrapped cold pack can help reduce pain and swelling, particularly during the first 24 hours.
Avoid placing ice directly on the skin.
4. Pain management
Give prescribed analgesia.
Regularly reassess pain and response to treatment.
5. Comfort measures
Warm sitz baths may provide comfort after the initial postpartum period if appropriate.
