MANAGEMENT OF 3RD STAGE BLEEDING
Steps of management
1. Placental site bleeding-
To palpate the fundus and massage the uterus to make it hard. The massage is to be done by placing four fingers behind the uterus and thumb in front.
To start crystalloid solution (NS or RL) with oxytocin (1L with 20 units) at 60 drops per minute and to arrange for blood transfusion if necessary.
Oxytocin 10 unit IM or methergine 0.2 mg is given intravenously.
To catheterize the bladder.
To give antibiotics (Ampicillin 2gm and Metronidazole 500mg IV)
2. Management of traumatic bleed
The uterovaginal canal is to be explored under general anesthesia after the placenta is expelled and haemostatic sutures are placed on the offending sites.
STEPS OF MANUAL REMOVAL OF PLACENTA
The patient is placed in lithotomy position. With all aseptic measures, the bladder is catheterized.
One hand is introduced into the uterus in cone shaped manner following the cord. While introducing the hand, the labia are separated by the fingers at the other hand.
Counter pressure on the uterine fundus is applied by the hand placed over the abdomens. The abdominal hand should steady the fundus and guide the movement of the fingers inside the uterine cavity till the placenta is completely separated.
Many women experience some minor disorders during pregnancy.
Every system of the body may be affected during pregnancy. These disorders, however , are not minor to the pregnant woman.
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 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.
Dinoprostone is a naturally occurring prostaglandin. It has important effect in labour. Also it stimulates osteoblasts to release factors which stimulates bone. As a prescription, it is used as a vaginal suppository, to prepare the cervix for labour and to induce labour.
An episiotomy is a cut (incision) through the area between your vaginal opening and your anus. This area is called the perineum. This procedure is done to make your vaginal opening larger for childbirth.

AMNIOINFUSION--
definition-An amnioinfusion is a technique of instilling an isotonic fluid {such as a normal saline or lactated ringer’s solution} into the amniotic cavity during labor to relieve umbilical cord compression and alleviate fetal distress from severe prolonged variable decelerations in the presence of oligohydramnios.
INDICATIONS
Fetal heart rate abnormalities
APGAR scores for those with low scores
Asphyxia during time of birth
Decreasing the rates of cesarean birth related with FHR problem
PROCEDURE
The amnio infusion procedure involves the use of an intrauterine pressure catheter (IUPC), or a single or double lumen type of IUPC.
The IUPC has been designed to attain an accurate monitoring of uterine contractions among women in the intrapartum period.
It has a special port from which the saline fluid or lactated ringer’s solution is being injected, passing through the tubing and going its way into the uterus.
An IUPC is inserted through standard technique once the membranes ruptures, and then it is attached to intravenous extension tubing. If IUPC is not available, a pediatric nasogastric tube can be used instead.
Lactated ringer’s solution without dextrose is infused into the amniotic cavity; normal saline can be an acceptable fluid alternative
Assisting Physician with Amnioinfusion
Explain the procedure to the patient.
Assist in dorsal recumbent position. Assist with draping and exposing vaginal area.
Connect IUPC tubing to IV fluid, flush
Connect the catheter to the monitor cable
Assist physician with insertion of double lumen IUPC and connect IV tubing to the amnioport to begin amnioinfusion.

Presenter: Dr. Faiza, Assistant Professor of Physiology
Qualifications:
MBBS (Best Graduate, AIMC Lahore)
FCPS Physiology
ICMT, CHPE, DHPE (STMU)
MPH (GC University, Faisalabad)
MBA (Virtual University of Pakistan)
Learning Objectives:
Describe the primary categories of smells and the concept of odor blindness.
Explain the structure and location of the olfactory membrane and mucosa, including the types and roles of cells involved in olfaction.
Describe the pathway and mechanisms of olfactory signal transmission from the olfactory receptors to the brain.
Illustrate the biochemical cascade triggered by odorant binding to olfactory receptors, including the role of G-proteins and second messengers in generating an action potential.
Identify different types of olfactory disorders such as anosmia, hyposmia, hyperosmia, and dysosmia, including their potential causes.
Key Topics:
Olfactory Genes:
3% of the human genome accounts for olfactory genes.
400 genes for odorant receptors.
Olfactory Membrane:
Located in the superior part of the nasal cavity.
Medially: Folds downward along the superior septum.
Laterally: Folds over the superior turbinate and upper surface of the middle turbinate.
Total surface area: 5-10 square centimeters.
Olfactory Mucosa:
Olfactory Cells: Bipolar nerve cells derived from the CNS (100 million), with 4-25 olfactory cilia per cell.
Sustentacular Cells: Produce mucus and maintain ionic and molecular environment.
Basal Cells: Replace worn-out olfactory cells with an average lifespan of 1-2 months.
Bowman’s Gland: Secretes mucus.
Stimulation of Olfactory Cells:
Odorant dissolves in mucus and attaches to receptors on olfactory cilia.
Involves a cascade effect through G-proteins and second messengers, leading to depolarization and action potential generation in the olfactory nerve.
Quality of a Good Odorant:
Small (3-20 Carbon atoms), volatile, water-soluble, and lipid-soluble.
Facilitated by odorant-binding proteins in mucus.
Membrane Potential and Action Potential:
Resting membrane potential: -55mV.
Action potential frequency in the olfactory nerve increases with odorant strength.
Adaptation Towards the Sense of Smell:
Rapid adaptation within the first second, with further slow adaptation.
Psychological adaptation greater than receptor adaptation, involving feedback inhibition from the central nervous system.
Primary Sensations of Smell:
Camphoraceous, Musky, Floral, Pepperminty, Ethereal, Pungent, Putrid.
Odor Detection Threshold:
Examples: Hydrogen sulfide (0.0005 ppm), Methyl-mercaptan (0.002 ppm).
Some toxic substances are odorless at lethal concentrations.
Characteristics of Smell:
Odor blindness for single substances due to lack of appropriate receptor protein.
Behavioral and emotional influences of smell.
Transmission of Olfactory Signals:
From olfactory cells to glomeruli in the olfactory bulb, involving lateral inhibition.
Primitive, less old, and new olfactory systems with different path
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.

RESULTS: Overall life span (LS) was 2252.1±1742.5 days and cumulative 5-year survival (5YS) reached 73.2%, 10 years – 64.8%, 20 years – 42.5%. 513 LCP lived more than 5 years (LS=3124.6±1525.6 days), 148 LCP – more than 10 years (LS=5054.4±1504.1 days).199 LCP died because of LC (LS=562.7±374.5 days). 5YS of LCP after bi/lobectomies was significantly superior in comparison with LCP after pneumonectomies (78.1% vs.63.7%, P=0.00001 by log-rank test). AT significantly improved 5YS (66.3% vs. 34.8%) (P=0.00000 by log-rank test) only for LCP with N1-2. Cox modeling displayed that 5YS of LCP significantly depended on: phase transition (PT) early-invasive LC in terms of synergetics, PT N0—N12, cell ratio factors (ratio between cancer cells- CC and blood cells subpopulations), G1-3, histology, glucose, AT, blood cell circuit, prothrombin index, heparin tolerance, recalcification time (P=0.000-0.038). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and PT early-invasive LC (rank=1), PT N0—N12 (rank=2), thrombocytes/CC (3), erythrocytes/CC (4), eosinophils/CC (5), healthy cells/CC (6), lymphocytes/CC (7), segmented neutrophils/CC (8), stick neutrophils/CC (9), monocytes/CC (10); leucocytes/CC (11). Correct prediction of 5YS was 100% by neural networks computing (area under ROC curve=1.0; error=0.0).
CONCLUSIONS: 5YS of LCP after radical procedures significantly depended on: 1) PT early-invasive cancer; 2) PT N0--N12; 3) cell ratio factors; 4) blood cell circuit; 5) biochemical factors; 6) hemostasis system; 7) AT; 8) LC characteristics; 9) LC cell dynamics; 10) surgery type: lobectomy/pneumonectomy; 11) anthropometric data. Optimal diagnosis and treatment strategies for LC are: 1) screening and early detection of LC; 2) availability of experienced thoracic surgeons because of complexity of radical procedures; 3) aggressive en block surgery and adequate lymph node dissection for completeness; 4) precise prediction; 5) adjuvant chemoimmunoradiotherapy for LCP with unfavorable prognosis.
