Hepatic coma is an advanced complication of liver failure characterized by reversible decreased neurologic function and loss of consciousness due to the liver's failure to detoxify toxic substances. It is caused by chronic liver disease, fulminant hepatic failure, or portosystemic shunts. Patients experience disturbances in consciousness, neurological signs, and mental changes. Treatment focuses on treating the underlying cause, decreasing ammonia production, and controlling risk factors through supportive care, lactulose, rifaximin, and L-ornithine/L-aspartate supplementation. Complications can include brain herniation, organ failure, and brain edema.

Liver or Hepatic disorders are common and may result from a virus or exposure to toxic substances such as alcohol.
Another liver disorder is cancer: hepatocellular carcinoma is a highly malignant tumor that is difficult to treat and often fatal.
Liver function is complex, and liver dysfunction affects all body systems.
For this reason, the nurse must understand how the liver functions and must have expert assessment and clinical management skills to care for patients undergoing complex diagnostic and treatment procedures.
The liver plays additional roles in detoxification of chemicals and synthesis and storage of important nutrients and The liver is especially important in the regulation of glucose and protein metabolism .
MEANING
Sudden and often temporary loss of kidney function.
DEFINITION
Acute renal failure (ARF) is an abrupt and sudden reduction in renal function resulting in the inability to excrete metabolic wastes and maintain proper fluid & electrolyte balance.
• It usually associated with oliguria (less than 500ml/day), no oliguria (greater than 800ml/day) or anuria (less than 50ml/day).
• BUN &creatinine values are elevated.
Etiology
ARF can be further divided into pre-renal, intra renal and post renal etiologies.
1) Pre- Renal causes
Are those that decrease effective blood flow to the kidney and cause a decrease in the glomerular filtration rate (GFR). Both kidneys need to be affected as one kidney is still more than adequate for normal kidney function.
Volume depletion resulting from:
• Hemorrhage
• Renal losses (diuretics, osmotic diuresis)
• Gastrointestinal losses (vomiting, diarrhea, nasogastric suction)
Impaired cardiac efficiency resulting from:
• Myocardia infraction
• Heart failure
• Dysrhythmias
• Cardiogenic shock
Vasodilation resulting from:
• Sepsis
• Anaphylaxis
• Antihypertensive medications or other medications that cause vasodilation.
2) Intrarenal causes
Refers to disease processes which directly damage the kidney itself. It can be due to one or more of the kidney’s structures including the glomeruli, kidney tubules or the interstitium.
Prolonged renal ischemia resulting from:
• Pigment nephropathy (associated with the breakdown of blood cells containing pigments that in turn occlude kidney structures)
• Myoglobinuria (trauma, crush injuries, burns)
• Hemoglobinreuria (transfusion reaction, hemolytic anemia)
Nephrotoxic agents such as:
• Aminoglycoside antibiotics (gentamycin, tobramycin)
• Radiopaque contrast agents
• Heavy metals (lead, mercury)
• Solvents and chemicals (ethylene glycol, carbon tetrachloride, arsenic)
• NSAIDS
• ACE inhibitors
Infections processes such as:
• Acute pyelonephritis
• Acute glomerulonephritis
3) Post renal causes
Refers to mechanical obstruction of urinary outflow, between the kidney and the urethral meatus, which includes urethral and bladder neck obstruction due to:
Calculi formation
Benign prostatic hyperplasia
Tumors
Strictures
Trauma (to back, pelvis or perineum)
Blood clots
Pathophysiology
The kidneys receive approximately one fourth of cardiac output; therefore, they are very sensitive to alteration in perfusion. Most cases of ARF are caused by ischemia episode. The pathophysiology of ARF is not completely understood.
PrerenalARF, is the result of impaired blood flow that leads to hypo perfusion of the kidney which causes decreased oxygen delivery that leads to hypoxemia and ischemia due to damage the kidney and glomerular filtration rate (GFR) decreases that leads to electrolyte imbalance and increased tubular reabsorption of sodium and water.
Intrarenal ARF is the result of actual parenchymal damage to the glomeruli or kidney

INTRODUCTION
Cancer is a general term used to refer to a condition where the body’s cells begin to grow and reproduce in an uncontrollable way. Lung cancers are the fourth most common cancer reported in the Indian males.
DEFINITION
Lung carcinoma is a malignant lung tumor characterized by uncontrolled cell growth in tissues of the lung. If left untreated, this growth can spread beyond the lung by the process of metastasis into nearby tissue or other parts of the body.
CAUSES
The most common causes of fracture include,
I. Tobacco smoke
Tobacco use is responsible for more than one of every six deaths. The younger a person is when he or she starts smoking, the greater the risk of developing lung cancer.
II. Secondhand smoke
Passive smoking has been identified as a possible cause of lung cancer in nonsmokers. People who are involuntarily exposed to tobacco smoke in a closed environment (house, automobile, and building) have an increased risk of lung cancer when compared with unexposed nonsmokers.
III. Environmental and occupational exposure
Various carcinogens have been identified in the atmosphere, including motor vehicle emissions and pollutants fromrefineries and manufacturing plants. High levels of radon have been associated with the development of lung cancer, especially when combined with cigarette smoking. Chronic exposure to industrial carcinogens, such as arsenic, asbestos, mustard gas, chromates, coke oven fumes, nickel, oil, and radiation has been associated with the development of lung cancer.
IV. Genetics
Some familial predisposition to lung cancer seems apparent, because the incidence of lung cancer in close relatives of patients with lung cancer appears to be two to three times that in the general population regardless of smoking status.
TYPES OF LUNG CANCER:
1. Small cell lung carcinoma
• Accounts for 15%-25% of lung cancers
• It is most malignant form
• Tends to spread early via lymphatic and bloodstream
• Is frequently associated with endocrine disturbances
• Predominantly central and can cause bronchial obstruction and pneumonia.
2. Non-small cell lung carcinoma
Is further classified by cell type,
Adenocarcinoma
• Most common type
• Accounts for approximately 30%-40% of lung cancers
• More common in women
• Often gas no clinical manifestations until widespread metastasis is present
• Usually begins in mucous glandular tissue, is most commonly located in peripheral portions of lungs.
Squamous cell carcinoma
• Second most common type of lung cancer
• Accounts for 30%-35% of lung cancers
• Is more common in men
• Arises from the bronchial epithelium of the lungs or bronchus, slow-growing cancer that usually begins in the bronchial tubes.
Large cell carcinoma
• The least common form
• Accounts for 5%-15% of lung cancers
• Composed of large sized cells that are anaplastic and often arise in the bronchi, commonly causes cavitation
• Is highly metastatic via lymphatic and blood.
STAGING OF NON-SMALL CELL LUNG C
Cirrhosis of liver is the end result of the hepatocellular injury
characterized by the presence of extensive fibrosis,
regenerative nodules and loss of liver architecture.

Health Education on prevention of hypertensionRadhika kulvi
Hypertension is a chronic condition of concern due to its role in the causation of coronary heart diseases. Hypertension is a worldwide epidemic and important risk factor for coronary artery disease, stroke and renal diseases. Blood pressure is the force exerted by the blood against the walls of the blood vessels and is sufficient to maintain tissue perfusion during activity and rest. Hypertension is sustained elevation of BP. In adults, HTN exists when systolic blood pressure is equal to or greater than 140mmHg or diastolic BP is equal to or greater than 90mmHg. The

3. ANATOMY AND
PHYSIOLOGY OF THE
LIVER
• Picture of the liver with some part
of the small intestines and the
pancreas
The liver is said to be the second largest organ of the body.
It is located just below the diaphragm at the upper right quadrant of the
abdomen and extent to the left.
It has a larger right lobe and smaller left lobe divided by falciform ligament.
Functions of the liver
The functional unit of the liver is the hepatocyte responsible for several
functions;
1. Maintains blood glucose level
2. Lipid metabolism for ATP
3. Protein synthesizes and conversion of it toxic into less harmful for
excretion
4. Synthesis of plasma proteins albuminalpha and beta globulins,
albumin, prothrombin, and fibrinogen.
5. Activation of drugs into active and inactive form
6. Stores vitamins (A, B12, D, E & K)
7. Excretion of bilirubin
8. Secretes bile which aids in dietary fats absorption
4. DEFINITION OF HEPATIC COMA
• Hepatic coma is advanced complication of liver failure characterized
by a reversible decrease in neurologic function, loss of consciousness
and other neuropsychiatric disorders as a resulting from failure of the
liver to detoxify toxic agents due to hepatic insufficiency and porto –
systemic shunt (abnormal connection between the portal vascular
system and systemic circulation).
5. PATHOPHYSIOLOGY
• A failure in the several functions of the liver especially in the detoxification
of the body due to endogenous cause e.g autoimmune or exogenous cause
e.g. toxins leads to accumulation, which may bypass liver’s vascular system
( portal vein and artery) and enters straight into circulation through porto-
systemic shunt (PSS), some PSS may be primary-congenital whiles others
are secondary – acquired.
• Physiologically blood exits the intestines, spleen and pancreas, and enters
the liver via the portal vein for metabolism and detoxification hence if a
shunt is present, the liver is deprived of factors which aid in it development
resulting in hepatic atrophy and insufficiency which then combine with
toxins and nutrient which intend crosses the BBB and resulting in
inflammation in the brain cells with it presenting clinical manifestation.
13. MANAGEMENT
Treatment goals
• Treat underlying cause
• Supportive measures
• Decreasing ammonia production in the colon
• Controlling of risk factors
14. Nursing management
• Such patient require ICU care due possible airway obstruction and
serious complications from the condition.
• Assess the airway and intubate
• Assess patient level of consciousness in order to aid in the treatment,
evaluation and prognosis
• Place a nasogastric tube for safe administration of nutrients and
medications.
• With the presence of infection antibiotics are often administered
empirically (without knowledge of the exact source and nature of the
infection).
15. Nursing management
• A diet with adequate protein and energy is therefore recommended.
• Some studies have shown benefit of administration of probiotics
("healthy bacteria").
16. Medical Management
• Lactulose/lactitol administration
Doses of 15-30 ml are typically administered three times a day; the
result is aimed to be 3–5 soft stools a day. There is decrease generation
of ammonia by bacteria, render the ammonia in absorbable by
converting it to ammonium (NH4+) ions, and increase transit of bowel
content through the gut. Also, studies show constipation to be a cause
for hepatic encephalopathy which leads to hepatic coma.
17. Medical Management
• Rifaximin
The antibiotic rifaximin may be recommended in addition to lactulose
for those with recurrent disease. It is a nonabsorbable antibiotic from
the rifamycin class. This is thought to work in a similar way to other
antibiotics but without the complications attached to neomycin or
metronidazole.
NB. Neomycin, metronidazole and other antibiotic may be used in the
treatment but due their complication it is not recommended.
18. Medical Management
L-ornithine and L-aspartate (LOLA)
• The combination of L-ornithine and L-aspartate (LOLA) lowers the
level of ammonia in a person's blood. LOLA lowers ammonia levels by
increasing the generation of urea through the urea cycle, a metabolic
pathway that removes ammonia by turning it into the neutral
substance urea.
19. COMPLICATIONS OF HEPATIC COMA
• Brain herniation
• Organ failure
• Brain edema and intracranial hypertension resulting in death
