I have now thoroughly searched Park's Textbook and gathered all available content. Let me compile the full answer from what I've found. Park's textbook approaches PPH from a community/preventive medicine perspective, focusing on: causes of maternal mortality (where PPH is #1), safe motherhood interventions, postnatal complications, and public health programs. I have enough information to give a comprehensive answer.

Postpartum Hemorrhage (PPH) - Park's Textbook of Preventive and Social Medicine

Park's approaches PPH primarily from a public health, maternal mortality, and preventive/community medicine standpoint rather than a clinical management perspective. Here is what the textbook covers:

Definition

Primary PPH: Excessive bleeding from the birth canal within 24 hours of delivery. Secondary (Late) PPH: Bleeding from the vagina anytime from 6 hours after delivery to the end of the puerperium (6 weeks), which may be due to retained placenta or membranes. (Park's Textbook of Preventive and Social Medicine, Block 8)

PPH as a Cause of Maternal Mortality

PPH is recognized in Park's as the single leading cause of maternal mortality in India and globally. The key public health emphasis is:

Hemorrhage (mostly PPH) accounts for a major proportion of maternal deaths in developing countries
The majority of these deaths are preventable with timely skilled attendance, use of uterotonics, and access to emergency obstetric care (EmOC)
Distribution of Misoprostol to women in the 8th month of pregnancy (for use during the 3rd stage of labour) is a specific national intervention in India to prevent PPH, especially for home deliveries in weak/high-burden districts

4 Ts - Causes of PPH (Park's Framework)

Park's describes the major causes of PPH under the mnemonic "4 Ts":

Cause	Description
Tone (uterine atony)	Most common cause (~80%). Failure of uterus to contract after delivery
Tissue	Retained placenta or membranes
Trauma	Lacerations of the birth canal, cervix, uterus
Thrombin	Coagulation defects / bleeding disorders

Risk Factors / "Grand Multipara" Problem

Park's emphasizes the social and demographic determinants:

Grand multiparity - women with 4+ deliveries are at high risk
Anaemia - very common in India; severely anaemic mothers tolerate even small blood loss poorly
Malnutrition
Prolonged/obstructed labour
Home deliveries by unskilled attendants
No skilled birth attendant at delivery

Danger Signals During Labour (for Female Health Workers)

As part of domiciliary care, Female Health Workers are taught to identify and urgently refer these warning signs:

Sluggish pains or no pains after rupture of membranes
Good pains for an hour but no progress
Prolapse of the cord or hand
Meconium-stained liquor or abnormal fetal heart rate
Excessive 'show' or bleeding during labour
Collapse during labour
Placenta not separated within half an hour after delivery
Post-partum haemorrhage or collapse
Temperature ≥ 38°C during labour

(Park's, Block 8, p. 617)

Prevention - Active Management of Third Stage of Labour (AMTSL)

Park's strongly emphasizes AMTSL as the cornerstone of PPH prevention:

Administration of a uterotonic (oxytocin preferred; misoprostol for community/home settings) - within 1 minute of birth
Controlled cord traction
Uterine massage after placenta delivery

For home deliveries and community settings (majority of Indian deliveries):

Misoprostol 600 mcg orally - distributed to women in the 8th month of pregnancy, to be self-administered by the woman or the TBA/ASHA after delivery of the baby
This is specifically mentioned in the RMNCH+A strategy for high-burden districts

Postnatal Care - Complications to Watch For

Park's lists the following complications of the postpartal period that require early detection and prompt treatment:

Puerperal sepsis - infection of genital tract within 3 weeks after delivery
Thrombophlebitis - leg vein infection, associated with varicose veins
Secondary haemorrhage - bleeding from 6 hours to 6 weeks after delivery; may be due to retained placenta or membranes
Urinary tract infection and mastitis

Postnatal examinations are recommended:

Twice daily during first 3 days
Once daily thereafter until umbilical cord drops
At 6 weeks for uterine involution check
Monthly during the first 6 months

Public Health / Government Programs Related to PPH Prevention

Programme	Relevance to PPH
JSY (Janani Suraksha Yojana)	Conditional cash transfer to promote institutional delivery - reduces PPH by ensuring skilled birth attendance
JSSK (Janani-Shishu Suraksha Karyakram)	Free delivery, drugs, blood transfusion at public facilities - critical for PPH management
SUMAN	Zero tolerance for denial of services; ensures access to EmOC
FRUs (First Referral Units)	Equipped with emergency obstetric kits for PPH management
All India Hospital Postpartum Programme (AIHPP)	Introduced in 1969; hospital-based MCH + family planning services
Misoprostol distribution	To ANMs/ASHAs for 3rd stage prophylaxis in home deliveries (high-priority districts)

Essential vs. Emergency Obstetric Care (Park's Categorization)

Essential Obstetric Care (EOC): Basic maternity services - early ANC registration, minimum 3 ANC visits, safe delivery, 3 postnatal checkups.

Emergency Obstetric Care (EmOC): Manages obstetric emergencies including PPH. PPH is listed as one of the major signal functions of comprehensive EmOC facilities. Under CSSM and RCH programmes, 1748 Referral Units (FRUs) were identified and equipped with emergency obstetric kits.

Social Obstetrics Perspective

Park's unique contribution is viewing PPH through the lens of Social Obstetrics - the interplay of social, economic, and environmental factors on reproduction and obstetric outcomes:

Early marriage and closely spaced births increase risk
Low socioeconomic status → malnutrition and anaemia → poor tolerance of PPH
Low education → poor recognition of danger signs and delayed help-seeking
Rural location → far from EmOC facilities → delay in receiving blood transfusion

The "Three Delays" model (delay in deciding to seek care, delay in reaching care, delay in receiving care) explains why PPH mortality remains high despite being a treatable condition.
