3 likes•421 views
Early postpartum hemorrhage (PPH) occurs within the first 24 hours after delivery, while late PPH occurs between 24 hours and 12 weeks. The four main causes of PPH are uterine atony (75-90% of cases), trauma to the birth canal, retained placental tissue, and clotting abnormalities. Visual assessment of blood loss, the most common method, is inaccurate and inconsistent between observers and often underestimates actual blood loss. Proper management of PPH requires recognizing risk factors and treating its underlying causes.

Therapeutic cooling during neonatal transport
Therapeutic hypothermia involves cooling newborn infants to 33-34°C for 72 hours to reduce brain injury from hypoxic-ischemic encephalopathy (HIE). Large clinical trials found cooling significantly reduced death and disability in infants with moderate-severe HIE. The mechanism involves reducing brain energy needs and excitotoxicity. Both active cooling devices and passive cooling with water/gel packs can achieve target temperature if monitored closely. Initiation within 6 hours and maintenance of core temperature in the target range are essential for benefit.
Preterm care and management
Preterm care involves respiratory management to maintain oxygen levels, thermoregulation through wrapping and warming, and careful skin care to prevent injury. Fluid and electrolyte needs require close monitoring due to immature renal function. Kangaroo mother care provides skin-to-skin contact and bonding. Consultations address neurodevelopment. Initial nutrition is colostrum or breast milk, adding fortifiers for preemies, and formula may be needed to meet caloric needs for growth.
Fetal assessment
We use a machine known as a fetal monitor to do a non-stress test. A non-stress test (NST) looks at your baby's heart rate over time (usually 20 to 30 minutes, but sometimes up to an hour). The monitor has two sensors that are placed on your belly with two belts that go around your waist.
Neonatal resuscitation 2012 AG
1. Neonatal resuscitation is required for approximately 10% of newborns, with 1% needing major intervention. Preterm infants are at higher risk of requiring resuscitation.
2. Effective ventilation is the most important part of neonatal resuscitation. Bag-mask ventilation should be performed if the heart rate is less than 100 beats per minute or if the infant has apnea or gasping respiration.
3. Chest compressions are performed if the heart rate remains below 60 beats per minute after 30 seconds of effective bag-mask ventilation with 100% oxygen. Compressions are done at a 3:1 ratio with ventilations at 90 compressions per minute.
Assessment of the new born
This document provides guidance on assessing the health of a newborn infant. It discusses evaluating the well-being of the fetus during pregnancy through tests such as non-stress tests and biophysical profiles. It also outlines examining the newborn after delivery to screen for problems, diagnose issues, and collect baseline medical information. The order of a full physical examination is provided, covering assessment of the skin, heart, lungs, abdomen, head, eyes, and other areas. Key vital signs and measurements are also reviewed.
WHO Breast Feeding Week 2021
This document discusses breastfeeding and provides information on breastfeeding globally and in India. Some key points:
- Breastfeeding has significant health benefits for both children and mothers. If breastfeeding were scaled up universally, over 820,000 child lives could be saved annually.
- Globally in 2020, 149 million children under 5 were stunted and 45 million were wasted. Exclusive breastfeeding rates are only around 44% globally.
- In India, only 24.5% of children are breastfed within the first hour of birth and exclusive breastfeeding rates decline rapidly from 20% by 6 months.
- WHO recommends exclusive breastfeeding for the first 6 months and continued breastfeeding for up to 2
Anemia in pregnancy
This document discusses anaemia in pregnancy, including:
- Definitions of anaemia in pregnancy according to WHO and CDC guidelines.
- Physiological changes in pregnancy that can lead to haemodilution and increased iron requirements.
- Causes, symptoms, and importance of diagnosing and treating maternal anaemia.
- Dietary sources and inhibitors of iron absorption.
- Diagnostic tests and treatment options for iron deficiency anaemia, including oral and parenteral iron supplementation as well as blood transfusions in severe cases.
- Screening and management considerations for thalassaemia.
Human Milk Banking
A human milk bank collects, screens, processes, stores, and dispenses donated human milk to infants who need it. Donated milk is preferable to formula or animal milk for preterm and low birth weight babies, as it decreases rates of health issues like necrotizing enterocolitis and improves outcomes. A human milk bank operates by registering and screening donors, collecting and pasteurizing donations, testing the milk, storing it frozen, and distributing it by prescription to reduce risks for recipient infants. Challenges include cost and availability, but human milk banks can improve infant health and reduce long-term costs from issues associated with prematurity.

Newborn & Pediatric Care
The assessment of a newborn is essential to ensure a successful transition from intrauterine to extrauterine life. It should be done immediately after birth, within the first 4 hours, and prior to discharge. The assessment includes evaluating the newborn's appearance, skin color, vital signs, muscle tone, reflexes, and activity level. Any abnormal findings should be documented and appropriate nursing care provided.
PPROM & PROM
Keith Moore Said "It has been a great pleasure for me to help clarify statements in the Qur'an about human development. It is clear to me that these statements must have come to Muhammad from God, or Allah, because most of this knowledge was not discovered until many centuries later. This proves to me that Muhammad must have been a messenger of God, or Allah."
Prematurity
This document discusses prematurity and the management of preterm infants. It defines prematurity as birth before 37 weeks gestation. It describes the problems that can occur in preterm infants relating to immaturity of organ systems, including respiratory issues, temperature regulation difficulties, neurological impairments, and metabolic concerns like hypoglycemia. The document outlines assessment and management approaches for various initial problems in the preterm newborn as well as long term issues involving development, medical complications, and social factors. Mortality and morbidity rates are provided based on gestational age and birth weight.
Post Partum Hemorrhage (PPH)
Postpartum hemorrhage (PPH) is defined as blood loss greater than 500 mL following vaginal birth or 1000 mL following c-section. It can occur within 24 hours (primary PPH) or 24 hours to 12 weeks (secondary PPH) postpartum and is a leading cause of maternal mortality. The 4 T's of PPH include tonicity (uterine atony), tissue (retained placental fragments), trauma, and thrombin abnormalities. A case is presented of a woman with risk factors of preeclampsia and prolonged labor who develops PPH. Her management involves IV fluids, uterotonics, uterine massage, and monitoring for signs of deterioration requiring additional interventions like embolization
Resuscitation of a Newborn
This document provides an overview of resuscitation procedures for newborns. It discusses that approximately 10% of newborns require some assistance to begin breathing, while 1% require extensive resuscitation measures. The document outlines the steps in newborn resuscitation, including clearing the airway, providing positive pressure ventilation, assessing heart rate and providing chest compressions and medications if needed. It provides guidance on indications for various resuscitation techniques and medications. The goal is to establish breathing, circulation and normalize heart rate and skin color through the ABCDE approach.

This document discusses various methods of antepartum fetal surveillance including fetal movement counting, non-stress tests, contraction stress tests, biophysical profiles, and Doppler ultrasounds. It provides details on how each test is performed and interpreted, and what outcomes they can predict regarding fetal wellbeing and risk of complications. The goal of antepartum fetal surveillance is to monitor the fetus, identify any risks, and prevent fetal death or neonatal complications through timely medical intervention when needed.
Obstetric emergencies
1. Obstetric emergencies include antepartum and postpartum hemorrhage from conditions like placenta previa, placental abruption, and uterine rupture.
2. Placenta previa is when the placenta implants in the lower uterine segment, potentially blocking the cervix and causing painless bleeding late in pregnancy.
3. Anesthetic management for placenta previa and other hemorrhages involves ensuring large bore IV access, blood product availability, and invasive monitoring while determining the need for general or neuraxial anesthesia depending on maternal stability.
Developmentally supportive neonatal care
This document discusses developmentally supportive care in the NICU. It describes how the NICU environment has transitioned from a technology-oriented space that could overstimulate or deprive infants to one that aims to mimic the womb and support brain development. It outlines principles of developmentally supportive care like NICU design, positioning, handling infants, and parental participation. Interventions like kangaroo care, non-nutritive sucking, massage therapy, and multimodal stimulation are described that aim to properly stimulate infant senses and support physiology and behavior.

Pph drill
Dr. Monika Madaan discusses postpartum hemorrhage (PPH), a leading cause of maternal mortality. PPH is defined as blood loss over 500ml after delivery. Risk factors include placenta previa/accreta, coagulopathy, overdistended uterus, grand multiparity, abnormal labor, and previous PPH history. Active management of the third stage of labor can help prevent PPH. Treatment involves resuscitation, fluid replacement, administering uterotonics and other drugs, uterine tamponade, compression sutures, devascularization, and hysterectomy if needed. New developments include tranexamic acid and recombinant factor VII. Proper documentation and debriefing are also
Steroids in neonatology Steroids in neonatology
This document discusses the use of steroids in neonatology, including both antenatal and postnatal applications. It begins by introducing the current recommendations for antenatal steroid therapy to reduce neonatal morbidity and mortality. It then covers the classification, mechanisms of action, benefits and considerations for administration of antenatal corticosteroids. It also discusses the use of postnatal steroids in the NICU to treat conditions like chronic lung disease. While noting both the benefits and risks, it concludes that postnatal steroids should be reserved for high-risk preterm infants who remain ventilator-dependent beyond 2-3 weeks of age.

Antepartum fetal assessment
This document summarizes antepartum fetal assessment techniques. It describes the aims of fetal monitoring as ensuring fetal growth and well-being. Various clinical evaluation methods are outlined, including fetal movements, breathing, biophysical profile, amniotic fluid volume, and Doppler velocimetry. Specific tests like non-stress tests and contraction stress tests are also defined. The document provides details on interpreting test results and guidelines for testing frequency from organizations like ACOG. The overall purpose is to screen for high-risk factors affecting the fetus and guide management to improve perinatal outcomes.
Therapeutic hypothermia
Therapeutic hypothermia, or targeted temperature management, involves reducing an infant's core body temperature to 33-34°C for 72 hours after birth to reduce the risk of brain injury from hypoxic-ischemic encephalopathy (HIE). Cooling should begin as soon as possible after birth and within 6 hours to be effective. It reduces mortality and neurodevelopmental disabilities at 18 months according to clinical trials. Eligible infants have gestational age ≥34 weeks, signs of encephalopathy, and evidence of perinatal asphyxia. Cooling must be performed carefully by lowering the temperature 0.5°C per hour and avoiding overcooling or rewarming too quickly.
Meconium aspiration syndrome (MAS)
This document discusses meconium aspiration syndrome (MAS), a condition where meconium is inhaled or aspirated by an infant before, during, or immediately after birth, causing respiratory distress. MAS occurs when an infant inhales meconium that has been passed in the amniotic fluid due to fetal distress. It presents with respiratory distress within the first hour of life. Diagnosis involves chest x-ray findings and blood gas analysis. Management includes supportive care, suctioning meconium from the airways, oxygen supplementation, and mechanical ventilation as needed. Prevention focuses on suctioning meconium from the nasopharynx after birth to reduce the risk of aspiration into the lungs.
Transient tachypnea of newborn ttn
This document discusses transient tachypnea of the newborn (TTN). TTN is a common condition caused by a delay in clearing fetal lung fluid after birth. It presents with respiratory distress and affects up to 15% of preterm infants. Risk factors include cesarean delivery, prematurity, and gestational diabetes. Diagnosis is based on clinical presentation, physical exam, and chest x-ray findings showing diffuse haziness. Treatment involves respiratory support and monitoring as symptoms typically resolve within 3 days. Medications are not routinely used or recommended for TTN management.
Newborn assessment
This document provides information on newborn assessment including risk factors, immediate post-birth care, transitional assessment, physical examination, and specific assessments of various body systems. Key points include:
- Maternal/fetal risk factors can be modified (e.g. smoking) or inherent (e.g. diabetes) and are important to anticipate potential problems.
- Immediate post-birth care includes maintaining ABCs, thermoregulation, vitamin K administration, breastfeeding, and skin care.
- The transitional period involves periods of reactivity in the first 24 hours as the newborn adapts to extrauterine life. Physical examination follows a head-to-toe sequence and includes measurements, vital signs
Cord prolapse
Umbilical cord prolapse occurs when the umbilical cord drops through the cervix ahead of the presenting fetal part during labor and delivery. This can lead to oxygen deprivation for the fetus if not promptly addressed. Cord prolapse is classified as overt if the cord is visible in the vaginal canal or occult if it is not visible but suspected based on fetal heart rate changes. Immediate cesarean delivery is usually required for overt prolapse while occult prolapse may allow continued monitoring and trial of vaginal delivery if the heart rate recovers. Factors that increase risk include premature delivery, multiple gestation, polyhydramnios, and breech presentation.
Neonatal thermoregulation
This document discusses the history and physiology of neonatal thermoregulation. It begins with the history of incubation from ancient Egypt and its application to premature infants in the 1800s. Key concepts discussed include the thermoneutral zone, factors affecting an infant's susceptibility to temperature changes, and the physiology of thermoregulation including brown adipose tissue. The document also covers the prevention, signs, and management of hypothermia in infants.
Antenatal Screening in Pregnancy ADBHUT MATRUTVA
This document discusses antenatal screening guidelines recommended by an expert group in India. It recommends screening in the first, second, and third trimesters to monitor fetal development and well-being and identify risks. Screening in the first trimester includes tests to check various health factors and screen for chromosomal anomalies. The second trimester screening includes additional tests and an anomaly scan. The third trimester screening focuses on monitoring the fetus for signs of distress through tests such as kick counts and cardiotocography. The goal is early detection of at-risk fetuses so they can receive timely care and intervention to prevent complications.
