Similar to Hemodialysis: Chapter 8, Complications During Hemodialysis, Part 2 - Dr.Gawad
Hemodialysis is a method for removing waste and excess fluid from the blood when the kidneys fail. It involves connecting the patient's blood to a dialysis machine via vascular access points. The three main types of access are catheters, arteriovenous fistulas, and synthetic grafts. Fistulas have the lowest risk of complications like infection but take time to mature before use. Potential side effects of hemodialysis include low blood pressure and symptoms from rapid fluid removal.

A group of nursing students presented a case study on subarachnoid hemorrhage. The presentation covered: an introduction to subarachnoid hemorrhage including causes and risk factors; a specific patient case including demographics, medical history, physical assessment findings and diagnostic test results; anatomy and physiology of the central nervous system; medical management including medications, interventions and treatment; nursing care and interventions; and a conclusion with recommendations. The presentation was outlined and included references.
This document discusses hemoptysis (coughing up blood). It defines hemoptysis and outlines its severity based on blood loss. The most common causes are tuberculosis, bronchiectasis, and lung cancers. A diagnostic evaluation involves history, physical exam, chest imaging like x-ray and CT, and bronchoscopy. Management depends on the severity, ranging from watchful waiting for mild cases to airway stabilization, bronchial artery embolization, and surgery for massive hemoptysis when more conservative options have failed. Endoscopic techniques like laser, electrocautery and hemostatic agents can help control bleeding locally.
The document discusses hemoptysis (coughing up blood from the lungs). It defines hemoptysis and outlines several learning objectives related to understanding the condition. Key points include:
- Hemoptysis is defined as spitting up blood originating from the lungs or bronchial tubes. Massive hemoptysis refers to coughing up over 100mL-1000mL of blood in 24 hours.
- Causes can include infections like tuberculosis, lung cancers, injuries or disorders affecting blood vessels in the lungs. Diagnostic tests include imaging like chest x-rays and CT scans, as well as sputum cultures and bronchoscopy.
- Treatment depends on the severity but may include medications to stop
Pleural effusion is an abnormal, excessive collection of fluid between the layers of the pleura that can impair breathing. It is caused by increased hydrostatic pressure or decreased oncotic pressure leading to increased fluid formation or decreased absorption. Common causes include congestive heart failure, infection, and cancer. Clinical features include chest pain, cough, fever, and shortness of breath. Management involves removing fluid through thoracentesis or chest tubes and treating the underlying cause.
Bleeding disorders result from problems with blood clotting and can range from mild to life-threatening. The coagulation cascade describes the series of biochemical reactions involved in clotting. There are two pathways - intrinsic and extrinsic - that activate clotting factors and ultimately form a fibrin clot. Common symptoms include bruising, nosebleeds, and heavy periods. Investigations may include blood tests of clotting factors and bleeding time. Specific deficiencies are diagnosed through factor assays and gene analysis. Treatment depends on the underlying condition.
This document provides an overview of hemoptysis, including:
1. Defining hemoptysis as the spitting of blood originating in the lungs or bronchial tubes and discussing massive hemoptysis.
2. Outlining the pathophysiology, etiologies, risk factors, clinical presentation, diagnostic measures, and management of hemoptysis.
3. Stating the learning objectives are for students to understand hemoptysis, be able to recognize it, discuss its pathophysiology and causes, compare it to hematemesis, recognize its clinical presentation, identify diagnostic measures, and outline its management.
Disseminated intravascular coagulation (DIC) is a condition in which blood clots form throughout the body, blocking small blood vessels. Symptoms may include chest pain, shortness of breath, leg pain, problems speaking, or problems moving parts of the body.
A condition affecting the blood's ability to clot and stop bleeding.
In disseminated intravascular coagulation, abnormal clumps of thickened blood (clots) form inside blood vessels. These abnormal clots use up the blood's clotting factors, which can lead to massive bleeding in other places. Causes include inflammation, infection and cancer.
Pleural fluid is the fluid found between the layers of the pleura surrounding the lungs. Normal pleural fluid acts as a lubricant, but excess fluid called a pleural effusion can build up due to conditions like heart failure, infection, or cancer. Diagnosis involves imaging tests and analyzing pleural fluid extracted via thoracentesis. Treatment depends on the underlying cause but may include drainage, medication, surgery, or pleurodesis to prevent recurrence. Blood tests analyze levels of cells and proteins to screen for and diagnose diseases, with different panels targeting areas like metabolic function, infection, cardiac health, and more. Abnormal results can indicate conditions affecting related organs and tissues.
Café Au Lait Spot is A Marker for Pheochromocytoma in Hypertensive Crisis Wit...YasserMohammedHassan1
Café au lait Spot is a marker for pheochromocytoma in hypertensive crisis but with a wide-differential diagnosis. Labetalol may be chosen in hypertensive crisis due to pheochromocytoma.
Hydrocephalus is an excessive accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain that results in enlarged ventricles and increased intracranial pressure. It can be caused by obstruction of CSF flow, overproduction of CSF, or impaired absorption of CSF. Common symptoms include an enlarged head size, vomiting, and headaches. Treatment options include the use of shunts to divert CSF from the brain to the abdominal cavity or endoscopic procedures. Prognosis depends on severity but can include long-term neurological and developmental issues if not treated effectively.
This document discusses coarctation of the aorta, including its development, presentation, management, and outcomes. It begins with an overview of the anatomy and embryological development of the aorta. Coarctation results from abnormal development of the 4th and 6th aortic arches. Presentation and management in the delivery room and NICU is then reviewed. Undiagnosed cases may present with signs of heart failure. Timing of ductal closure is also an important factor. Surgical intervention, outcomes, complications, and long-term issues are then described. Neurologic abnormalities can occur pre- and post-operatively. Overall, outcomes have significantly improved with early diagnosis and surgical repair.
Hemophilia is a genetic bleeding disorder caused by mutations that impair blood clotting abilities. There are three main types (A, B, C) defined by which clotting factor is deficient. Type A is most common, affecting about 1 in 5,000 male births. Symptoms include excessive bleeding from minor injuries, heavy menstrual periods, or bleeding into joints and muscles. Diagnosis involves blood tests to check clotting factor levels and ability to clot. Treatment replaces the missing clotting factor through injections to allow proper clot formation and prevent bleeding complications.
This document provides information about shock and its nursing management. It begins with an introduction to shock, defining it as a life-threatening condition caused by inadequate blood flow to tissues. It then outlines the stages of shock as initial, compensatory, progressive, and irreversible. The main types of shock discussed are hypovolemic, cardiogenic, neurogenic, septic, and anaphylactic. For each type, causes, signs and symptoms, and nursing care are described. The document concludes with test questions to assess learning.
Hemorrhage is the loss of blood from blood vessels. It can lead to shock if severe. The document discusses the definition, types, causes, signs and symptoms, diagnostic tests, and treatment of hemorrhage. Treatment involves arresting the hemorrhage through direct pressure, elevation, and other measures. Medical management includes fluid replacement, supplemental therapy, and measures for oxygenation and cardiac function. Nursing care focuses on thorough assessment and monitoring of the patient.
This topic is under the General Principles of Surgery. It is very important for MBBS - Students. New method of resuscitation called the Damaged Control Resuscitation is carried out in controlling the hemorrhage.
The abnormality seen on this HRCT image is predominantly subpleural and basal. There are bilateral reticular opacities in the subpleural regions extending into the bases posteriorly. The lung apices and upper lobes appear relatively spared.

Ventilation Perfusion Ratio, Physiological dead space and physiological shuntMedicoseAcademics
In this insightful lecture, Dr. Faiza, an esteemed Assistant Professor of Physiology, delves into the essential concept of the ventilation-perfusion ratio (V˙/Q˙), which is fundamental to understanding pulmonary physiology. Dr. Faiza brings a wealth of knowledge and experience to the table, with qualifications including MBBS, FCPS in Physiology, and multiple postgraduate degrees in public health and healthcare education.
The lecture begins by laying the groundwork with basic concepts, explaining the definitions of ventilation (V˙) and perfusion (Q˙), and highlighting the significance of the ventilation-perfusion ratio (V˙/Q˙). Dr. Faiza explains the normal value of this ratio and its critical role in ensuring efficient gas exchange in the lungs.
Next, the discussion moves to the impact of different V˙/Q˙ ratios on alveolar gas concentrations. Participants will learn how a normal, zero, or infinite V˙/Q˙ ratio affects the partial pressures of oxygen and carbon dioxide in the alveoli. Dr. Faiza provides a detailed comparison of alveolar gas concentrations in these varying scenarios, offering a clear understanding of the physiological changes that occur.
The lecture also covers the concepts of physiological shunt and dead space. Dr. Faiza defines physiological shunt and explains its causes and effects on gas exchange, distinguishing it from anatomical dead space. She also discusses physiological dead space in detail, including how it is calculated using the Bohr equation. The components and significance of the Bohr equation are thoroughly explained, and practical examples of its application are provided.
Further, the lecture examines the variations in V˙/Q˙ ratios in different regions of the lung and under different conditions, such as lying versus supine and resting versus exercise. Dr. Faiza analyzes how these variations affect pulmonary function and discusses the abnormal V˙/Q˙ ratios seen in chronic obstructive lung disease (COPD) and their clinical implications.
Finally, Dr. Faiza explores the clinical implications of abnormal V˙/Q˙ ratios. She identifies clinical conditions associated with these abnormalities, such as COPD and emphysema, and discusses the physiological and clinical consequences on respiratory function. The lecture emphasizes the importance of understanding these concepts for medical professionals and students, highlighting their relevance in diagnosing and managing respiratory conditions.
This comprehensive lecture provides valuable insights for medical students, healthcare professionals, and anyone interested in respiratory physiology. Participants will gain a deep understanding of how ventilation and perfusion work together to optimize gas exchange in the lungs and how deviations from the norm can lead to significant clinical issues.

Seated patients: Air travels to the
cerebral venous system and
obstructs it
Recumbent
patients
The air enters the heart (churning
sound) and obstructs the right
ventricular outflow
Further air
passage to
the lungs
obstructs
pulmonary
capillaries
Further passage of air across the pulmonary capillary bed
into the left ventricle can result in air embolization to the
arteries of:

Mild disequilibrium Severe disequilibrium (seizures and coma)
• Symptomatic treatment.
• The blood and dialysate flow rates should be
reduced.
• The ultrafiltration rate should be reduced too.
• Glucose or hypertonic sodium chloride solutions
may be given.
• Early termination of the dialysis session should
be considered, especially in acutely uremic
patients.
• Dialysis should be stopped.
• First aid measures for seizure management must
be taken.
• Intravenous mannitol, hypertonic saline, or
glucose may be of benefit.
• If seizures and coma are due to disequilibrium
syndrome, the patient should improve within 24
hours.
Exclude other causes of seizures: Other causes of seizures in dialysis patients rather than disequilibrium
syndrome should be excluded as early as possible, especially if the patient does not improve within a 24-
hour period.

48. In case of acute dialysis for a patient with
acute uremia
• Avoid prescribing aggressive dialysis sessions
• Urea reduction ratio (URR) target 30-40%
• Severely acidotic patients: initial dialysis treatments should be with
reduced dialysate bicarbonate
• Avoid using low dialysate sodium (>2–3 mmol/L less than the plasma
sodium level)
• Hypernatremic patients: uremia and hypernatremia correction should
not be attempted simultaneously.

49. In case of chronic dialysis
• Using sodium dialysate of at least 140 mmol/L can minimize the
incidence of disequilibrium syndrome.
• Sodium modeling: Although it decreases the occurrence of
disequilibrium syndrome, it has many drawbacks.

Immediate management:
- Terminate the dialysis session.
- Secure vascular access.
- Ensure the patient is not in danger
of injury and is in a secure setting.
- Administer intravenous fluids and
oxygen as required.
- The majority of seizures resolve
spontaneously within five minutes.
If a patient continues to seize:
- Achieve airway protection and
patient stabilization.
- Administering intravenous
benzodiazepines is the treatment of
choice to terminate the seizures.
- Refer the patient for neurology
consultation.
