Maternal collapse by dr alka mukherjee &; dr apurva mukherjeealka mukherjee
Not all maternal deaths are preceded by an identifiable collapse, and not all maternal collapses result in death. Maternal collapse occurs any time during pregnancy, up to 42 days following delivery and is an acute event involving cardiorespiratory systems and/or brain, resulting in impaired consciousness or death.1
Maternal deaths are generally quantified as a maternal mortality ratio (MMR), expressed as the number of maternal deaths per 100,000 women giving birth. It includes deaths that occur due to complications of the pregnancy (direct deaths), and those resulting from worsening of other disease processes due to the pregnancy (indirect deaths). Deaths that occur from causes completely unrelated to pregnancy or birth are termed When faced with an acute maternal collapse, it is helpful to think of potential causes as falling into five categories, or the 5 Hs for simplicity:4
Head including eclampsia, stroke, epilepsy, vasovagal
Heart including myocardial infarction, arrhythmia, cardiomyopathy, thoracic aortic dissection
Hypoxia including pulmonary embolus, pulmonary oedema, anaphylaxis, asthma
Haemorrhage including abruption, uterine atony, genital tract trauma, uterine rupture, uterine inversion, ruptured aortic aneurysm
wHole body and Hazards amniotic fluid embolus, hypoglycaemia, trauma, anaesthetic complications, drug reactions (illicit or prescribed), sepsis
The likelihood of any one of these being causative will obviously depend somewhat on the timing of the collapse – early or late pregnancy, intrapartum, immediately postpartum, remotely postpartum.
Maternal cardiac arrest represents a small subset of women affected by maternal collapse. The incidence is approximately 1 in 30,000 ongoing pregnancies, with a high likelihood of death for both the mother and the fetus. The vast majority of us will never need to attend a maternal cardiac arrest, and doing so is uniquely stressful. For these reasons, it is important to have a framework in mind of how to deal with a maternal cardiac arrest, and to have practised the response to this situation.
incidental deaths, and are not included in calculation of the MMR.
• Several other risk factors for maternal death are recognised. These include:
• Maternal age 35 and older
• Obesity
• Lower socioeconomic status
• Pre-existing mental health issues, substance use and domestic violence, all of which may be exacerbated by pregnancy and the puerperium
• Medical co-morbidities, particularly asthma, autoimmune diseases, inflammatory and atopic disorders, haematological disorders, essential hypertension, infections and musculoskeletal disorders
One of the important developments in improving identification of a pregnant or postnatal patient at risk of collapse during hospital admission has been the development of maternity-specific Early Warning Charts.

New Directions in Targeted Therapeutic Approaches for Older Adults With Mantl...i3 Health
i3 Health is pleased to make the speaker slides from this activity available for use as a non-accredited self-study or teaching resource.
This slide deck presented by Dr. Kami Maddocks, Professor-Clinical in the Division of Hematology and
Associate Division Director for Ambulatory Operations
The Ohio State University Comprehensive Cancer Center, will provide insight into new directions in targeted therapeutic approaches for older adults with mantle cell lymphoma.
STATEMENT OF NEED
Mantle cell lymphoma (MCL) is a rare, aggressive B-cell non-Hodgkin lymphoma (NHL) accounting for 5% to 7% of all lymphomas. Its prognosis ranges from indolent disease that does not require treatment for years to very aggressive disease, which is associated with poor survival (Silkenstedt et al, 2021). Typically, MCL is diagnosed at advanced stage and in older patients who cannot tolerate intensive therapy (NCCN, 2022). Although recent advances have slightly increased remission rates, recurrence and relapse remain very common, leading to a median overall survival between 3 and 6 years (LLS, 2021). Though there are several effective options, progress is still needed towards establishing an accepted frontline approach for MCL (Castellino et al, 2022). Treatment selection and management of MCL are complicated by the heterogeneity of prognosis, advanced age and comorbidities of patients, and lack of an established standard approach for treatment, making it vital that clinicians be familiar with the latest research and advances in this area. In this activity chaired by Michael Wang, MD, Professor in the Department of Lymphoma & Myeloma at MD Anderson Cancer Center, expert faculty will discuss prognostic factors informing treatment, the promising results of recent trials in new therapeutic approaches, and the implications of treatment resistance in therapeutic selection for MCL.
Target Audience
Hematology/oncology fellows, attending faculty, and other health care professionals involved in the treatment of patients with mantle cell lymphoma (MCL).
Learning Objectives
1.) Identify clinical and biological prognostic factors that can guide treatment decision making for older adults with MCL
2.) Evaluate emerging data on targeted therapeutic approaches for treatment-naive and relapsed/refractory MCL and their applicability to older adults
3.) Assess mechanisms of resistance to targeted therapies for MCL and their implications for treatment selection
Flu Vaccine Alert in Bangalore Karnatakaaddon Scans
As flu season approaches, health officials in Bangalore, Karnataka, are urging residents to get their flu vaccinations. The seasonal flu, while common, can lead to severe health complications, particularly for vulnerable populations such as young children, the elderly, and those with underlying health conditions.
Dr. Vidisha Kumari, a leading epidemiologist in Bangalore, emphasizes the importance of getting vaccinated. "The flu vaccine is our best defense against the influenza virus. It not only protects individuals but also helps prevent the spread of the virus in our communities," he says.
This year, the flu season is expected to coincide with a potential increase in other respiratory illnesses. The Karnataka Health Department has launched an awareness campaign highlighting the significance of flu vaccinations. They have set up multiple vaccination centers across Bangalore, making it convenient for residents to receive their shots.
To encourage widespread vaccination, the government is also collaborating with local schools, workplaces, and community centers to facilitate vaccination drives. Special attention is being given to ensuring that the vaccine is accessible to all, including marginalized communities who may have limited access to healthcare.
Residents are reminded that the flu vaccine is safe and effective. Common side effects are mild and may include soreness at the injection site, mild fever, or muscle aches. These side effects are generally short-lived and far less severe than the flu itself.
Healthcare providers are also stressing the importance of continuing COVID-19 precautions. Wearing masks, practicing good hand hygiene, and maintaining social distancing are still crucial, especially in crowded places.
Protect yourself and your loved ones by getting vaccinated. Together, we can help keep Bangalore healthy and safe this flu season. For more information on vaccination centers and schedules, residents can visit the Karnataka Health Department’s official website or follow their social media pages.
Stay informed, stay safe, and get your flu shot today!
Acute scrotum is a general term referring to an emergency condition affecting the contents or the wall of the scrotum.
There are a number of conditions that present acutely, predominantly with pain and/or swelling
A careful and detailed history and examination, and in some cases, investigations allow differentiation between these diagnoses. A prompt diagnosis is essential as the patient may require urgent surgical intervention
Testicular torsion refers to twisting of the spermatic cord, causing ischaemia of the testicle.
Testicular torsion results from inadequate fixation of the testis to the tunica vaginalis producing ischemia from reduced arterial inflow and venous outflow obstruction.
The prevalence of testicular torsion in adult patients hospitalized with acute scrotal pain is approximately 25 to 50 percent

The prostate is an exocrine gland of the male mammalian reproductive system
It is a walnut-sized gland that forms part of the male reproductive system and is located in front of the rectum and just below the urinary bladder
Function is to store and secrete a clear, slightly alkaline fluid that constitutes 10-30% of the volume of the seminal fluid that along with the spermatozoa, constitutes semen
A healthy human prostate measures (4cm-vertical, by 3cm-horizontal, 2cm ant-post ).
It surrounds the urethra just below the urinary bladder. It has anterior, median, posterior and two lateral lobes
It’s work is regulated by androgens which are responsible for male sex characteristics
Generalised disease of the prostate due to hormonal derangement which leads to non malignant enlargement of the gland (increase in the number of epithelial cells and stromal tissue)to cause compression of the urethra leading to symptoms (LUTS

Ethanol (CH3CH2OH), or beverage alcohol, is a two-carbon alcohol
that is rapidly distributed in the body and brain. Ethanol alters many
neurochemical systems and has rewarding and addictive properties. It
is the oldest recreational drug and likely contributes to more morbidity,
mortality, and public health costs than all illicit drugs combined. The
5th edition of the Diagnostic and Statistical Manual of Mental Disorders
(DSM-5) integrates alcohol abuse and alcohol dependence into a single
disorder called alcohol use disorder (AUD), with mild, moderate,
and severe subclassifications (American Psychiatric Association, 2013).
In the DSM-5, all types of substance abuse and dependence have been
combined into a single substance use disorder (SUD) on a continuum
from mild to severe. A diagnosis of AUD requires that at least two of
the 11 DSM-5 behaviors be present within a 12-month period (mild
AUD: 2–3 criteria; moderate AUD: 4–5 criteria; severe AUD: 6–11 criteria).
The four main behavioral effects of AUD are impaired control over
drinking, negative social consequences, risky use, and altered physiological
effects (tolerance, withdrawal). This chapter presents an overview
of the prevalence and harmful consequences of AUD in the U.S.,
the systemic nature of the disease, neurocircuitry and stages of AUD,
comorbidities, fetal alcohol spectrum disorders, genetic risk factors, and
pharmacotherapies for AUD.
2. Definition
• Shock is a critical condition an da life
threatening medical emergency.
• Shock results from acute , generalized ,
inadequate perfusion of below the tissues
needed to deliver the oxygen and nutrient for
normal.
5. Pathophysiology
• Untreated shock progresses through three
stages as shown in below table.
• inadequate management allows shock to
progressively worsen passing through until
death occurs.
6. Diagnosis
• There are no laboratory test for shock
• A high index of susupicion and physical signs
of inadequate tissue perfusion and
oxygenation are the basis for initiating prompt
management.
• Initial management does not rely on
knowledge of the underlying cause.
7. Initial management
• Maintain ABC
• Airway should assured - oxygen 15lt/min.
• Breathing – ventilation should be checked and
support if inadequate
• Circulation- (with control of hemorrhage)
– Two wide bore canulla
– Restore circulatory volume and reverse hypotention
with crystalloid.
– Crossmatch, arrange and give blood if necessary.
– See for response such as , vital signs
9. Management
• As above measurement for basic shock management then
treat specific cause.
• Laparotomy for ectopic pregnancy
• Sucction evacution for incomplete abortion .
• management of uterine atony
– Optimise uterine tone- give uterotonic agent
– Surgery- blynch suture, balloon catheter etc.
• Repair of laceration
• Management of uterine rupture
– Stop oxytoin infusion if running
– Continuous maternal and fetal monitoring
– Emergency laparotomy with rapid operative delivery
– Cesarean hysterectomy may need to perform if hemorrhage is
not controlled.
10.
11. Management of hemorrhegic shock
contd…
• Management of uterine inversion.
– Replacement of the uterus needs to be
undertaken quickly as delay makes replacement
more difficult.
– Administer toloclytics to allow uterine relaxation.
– Replacement under taken ( with placenta if still
attached)-manually by slowly and steadily
pushingupwards, with hydrostatic pressure or
surgically.
13. SEPTIC SHOCK
• This is sepsis with hypotention despite
adequate fluid resuscitation.
• To diagnose septic shock following two
criteria must be met
– Evidence of infection through a positive blood
culture.
– Refractory hypotention- hypotention despite of
adequate fluid resuscitation.
14. Predisposing factors for sepsis in
obstetrics
• Post cesarean delivery endoture of memetritis
• Prolonged rupture of membranes
• Retained products of conception
• Cerclage in presence of rupture membraned
• Intraamniotic infusion
• Water birth
• Retained product of conception
• Urinary tract infection
• Toxic shock syndrome
• Necrotising Fascitis
15. Clinical features
• Symptoms of sepsis
– Abdominal pain
– Vomiting
– diarrhoea
• Signs of sepsis
– Tachycardia ,Pallor
– Clamminess
– Peripheral shutdown
– Systemic inflammation
– Fever or hypothermia
– Tachypnoea
– Cold peripheries
– Hypotention
– Confuion
– Oliguria
– Altered mental state
16. Special aspects in management of
septic shock
• Transfer to a higher level facility .
• Invasive monitoring will inevitably be
necessary
• Obtain blood culture , wound swab culture
and vaginal swab culture.
• Start broad spectrum antibiotics .
• Removal of infected tissues .
17. Cardiogenic shock
• Failure of heart to provide adequate output lead
to tissue under perfussion. In addition to under
perfusion , blood and tissue oxygenation can also
be exacerbated because of the back pressure on
lungs that lead to pulmonary edema.
• Pregnancy puts progressive strain on the heart as
progresses.
• Preexisting cardiac disease places the parturient
at particular risk.
• Cardiac related death in pregnancy is the second
most common cause of death in pregnancy.
18. Anaphylaxis
• A seriout is rapid onset as allergic reaction
that is rapid onset and may cause death.
• It is a relatively uncommon event in
pregnancy but has serious implications for
bothmother and fetus.
21. Clinical features
• Cutaneous
– Flushing, pruritis, urticaria , rhinitis, conjunctival erythema,
lacrymation.
• Cardiovascular
– Cardiovascular collapse, hypotention, vasodialation and erythema,
pale clammy cool skin, diaphoresis, nausea and vomiting
• Respiratory
– Stridor , wheezing, dyspnoea, cough, chest tightness, cyanosis,
condusion.
• Gastrointestinal
– Nausea vomiting , abdominal pain , pelvic pain
• Central nervous system
– Hypotention – collapse with or without unconsiousness, dizziness ,
incontinence
– Hypoxia – causes confusion.
22. Management
• Immediate
– Stop adm. of suspected agent and call for help
– Airway maintenance
– Circulation
– Give epinephrine IM and repeat every 5-15min in titrated until
improvement.
– In severe hypotension intravenous epinephrine should be given.
– Rapid intravascular volume expansion with crystalloid solution.
• Secondary
– If hypotension persist alternative vasopressor agent should use.
– Atropine if persistant bradycardia
– If bronchospasm persist nebulize with salbutamol
– Antihistaminics
– Steroids
– All patient with anaphylactic shock should reffered to critical care
23. Distributive shock
• In distributive shock there is no loss in
intravascular volume or cardiac function.
• The primary defect is massive vasodilation
leading to relative hypovolemia, reduced
perfusion pressure , so poorer flow to the
tissues.
24. Causes
• Spinal injuries- Neurogenic shock
– Spinal cord injuries may produce hypotension and
shock as a result of sympathetic nervous system
dysfunction.
– Resuscitation , vasopressor agent and atropine may
required in management because spinal injury leads
bradycardia due to unapposed vagal stimulation.
• Anesthesia -High spinal block
– Basic ABC managemengt
– Ventilation if needed
