Streszczenie:

Assessment of right ventricular (RV) size, function, and haemodynamics has been challenging because of its unique cavity geometry. Conventional two-dimensional assessment of RV function is often qualitative. Doppler methods involving tricuspid inflow and pulmonary artery flow velocities, which are influenced by changes in pre- and afterload conditions, may not provide robust prognostic information for clinical decision making. Recent advances in echocardiographic assessment of the RV include tissue Doppler imaging, speckle-tracking imaging, and volumetric three-dimensional imaging, but they need specific training, expensive dedicated equipment, and extensive clinical validation. However, assessment of RV function is crucial, especially in patients with signs of right-sided failure and those with congenital or mitral valve diseases. This chapter aims to address the role of the various echocardiographic modalities used to assess RV and pulmonary vascular bed function. Special emphasis has been placed on technical considerations, limitations, and pitfalls of image acquisition and analysis.

Streszczenie:

Under normal conditions, the right ventricle (RV) virtually acts as a passive conduit. In critically-ill patients many situations induce uncoupling between the right ventricle and pulmonary circulation, leading to RV systolic dysfunction, then failure. Mechanical ventilation has a major impact by decreasing RV preload, but also significantly increasing RV afterload. RV function should thus always be interpreted and re-evaluated in the light of respiratory mechanics and ventilator settings. RV systolic function is key to the patient’s haemodynamic profile and must be monitored to achieve optimal haemodynamic management. Echocardiography is the best compromise between clinical effectiveness and invasiveness to monitor RV function. A limitation is its inability to monitor haemodynamics continuously. Acute cor pulmonale is defined by the combination of RV dilatation with paradoxical septal motion during systole. In conclusion, RV function monitoring is strongly recommended in many situations encountered in the intensive care unit, such as ARDS, septic shock, and pulmonary embolism. Many devices are available, but echocardiography constitutes the best compromise between accuracy and invasiveness.

Streszczenie:

The management of hypotension during spinal anaesthesia for caesarean delivery remains a challenge for anaesthesiologists. Close control of maternal haemodynamics is of great importance for maternal and fetal safety, as well as maternal comfort. Haemodynamic responses to spinal anaesthesia are influenced by aortocaval compression, the baricity and dose of local anaesthetic and opioid employed, the rational use of fluids, and the goal-directed use of vasopressors. The most common response to spinal anaesthesia is hypotension and an increased heart rate, which reflects a decreased systemic vascular resistance and a partial compensatory increase in cardiac output. Phenylephrine is therefore the vasopressor of choice in this scenario. Less commonly, hypotension and bradycardia may occur, possibly due to the activation of cardiac reflexes. This requires anticholinergics and/or ephedrine. The rarest occurrences are persistent refractory hypotension, or high spinal block with respiratory failure. Special considerations include patients with severe pre-eclampsia, in whom spinal anaesthesia is associated with haemodynamic stability, and less hypotension than in the healthy patient. Careful use of neuraxial anaesthesia in specialized centres has an important role to play in the management of patients with cardiac disease, in conjunction with careful monitoring. Prevention is better than cure, but should hypotension occur, rapid intervention is essential, based upon the exact clinical scenario and individual haemodynamic response.

Streszczenie:

Fluid and circulatory management is an integral part of the peri-operative care of critically-ill patients. Precisely estimating the volumetric needs of post-operative patients remains difficult. While the majority of patients tolerate intra-operative fluid loss easily, patients with reduced physiological reserve present more of a challenge. Targeting specific physiological goals and optimizing haemodynamics with fluids and inotropes, means outcomes of these patients can be improved. This approach is often referred as goal-directed therapy (GDT). ‘Individualized goal-directed therapy’ can vary in timing, monitoring techniques, and endpoints used. The emergence of minimal invasive devises has allowed us to integrate cardiac output monitoring as a safe and reliable tool in the routine care of high risk patients. This dynamic assessment of haemodynamics provides a reliable technique to assess volume responsiveness and guide fluids to optimize cardiac output and oxygen delivery.

Streszczenie:

This chapter discusses key components of cardiovascular physiology applicable to clinical practice in the field of anaesthesiology. From theory development to ground-breaking innovations, the history of cardiac and vascular anatomy, as well as physiology, is presented. Utilizing knowledge of structure and function, parameters created have allowed adequate patient clinical assessment and guided interventions. A review of concepts reveals the impact of multiple physiological variables on a patient’s haemodynamic state and the need for more accurate and efficient measurements. In particular, it is noted that a more reliable index of ventricular contractility is the end-systolic elastance rather than the ejection fraction. Constant direct preload assessment has not yet been achieved but continues to be determined through surrogate variables, and continuous cardiac output monitoring for oxygen delivery, although advancing, has limitations. Considering the effect of compound factors perioperatively, especially heart failure, modifies the goals and interventions of anaesthetists to achieve improved outcomes. Therefore, medical management prior to surgery and complete assessment through history, physical examination, and diagnostic tests are a priority. This chapter also details the expectations following volume expansion to augment haemodynamics during surgery, the concept of functional haemodynamic monitoring, and limitations to the parameters applied in assessing fluid responsiveness. Challenging the accuracy of conventional indices to predict volume status led to the use of goal-directed therapy, reducing morbidity and minimizing length of hospital stay. The mainstay of this chapter is to reinforce the relevance of advances in haemodynamic monitoring and homeostasis optimization by anaesthetists during surgery, using fundamental concepts of cardiovascular physiology.

Streszczenie:

Pericardial disease leading to pericardial effusion (PEF) is a common clinical disorder. The most common causes are viral infections, metastatic cancer, renal disease, and bleeding disorders. PEF that accumulates slowly can become quite large before haemodynamic embarrassment occurs, while PEF that accumulates rapidly from trauma or aortic dissection can be small,yet cause haemodynamic embarrassment. As the PEF increases in size, the pressure in the pericardial space increases, leading to a decrease in atrial and ventricular chamber sizes, and limiting filling of the chambers. Ultimately, cardiac output is decreased,resulting in cardiac tamponade. When the limits of the pericardial stretch are reached, the volume in the pericardial sac becomes fixed. Any additional increase of PEF results in decreased cardiac size and any change in chamber size with respiration results in a paradoxical change in size of the other chambers. Tamponade is divided into three phases based on changes in pericardial and arterial pressure and cardiac output. Doppler echocardiography is the cornerstone of the diagnosis, follow-up, and management of PEF. It provides information about the presence, size, and location of the PEF, its impact on right ventricle, right atrium, and inferior vena cava size, and assesses tamponade physiology. Comorbid conditions may modify the signs of tamponade and need to be considered during the clinical assessment. Tamponade is not an all-or-nothing diagnosis, but instead should be viewed along a continuum of progressively worsening haemodynamics.

The diagnostic power of two-dimensional (2D) echocardiography resides not only in its capability of providing anatomical information and of studying myocardial contractile function, but also in the possibility of performing a non-invasive haemodynamic assessment. Such non-invasive haemodynamic assessment is the subject of this chapter.2D echocardiography, colour flow imaging, and Doppler modality make this haemodynamic assessment possible, by studying the following parameters: ◆ Blood flow velocities. ◆ Transvalvular pressure gradients. ◆ Valvular areas. ◆ Stroke volume, regurgitant volume, and regurgitant fraction. ◆ Cardiac function.The application of these concepts in clinical practice will be explained through this chapter. They can be summarized in the following points: ◆ The study of valvular insufficiencies. ◆ The study of the valvular stenosis. ◆ The study of intracardiac shunts. ◆ The study of myocardial systolic and diastolic function. ◆ The estimation of intracardiac pressures.Finally, non-invasive haemodynamic study represents an alternative to invasive procedures in some clinical circumstances and it is very important in the diagnostic and therapeutic decision making. Therefore, it is necessary for the cardiologist to understand how this echocardiographic study is performed, as well as its advantages and limitations.

Ischaemic nephropathy describes loss of renal function or renal parenchyma due to stenosis or occlusion of the renal artery or its branches. In the Western world, this is usually the result of atherosclerotic renovascular disease, but other aetiologies include arteritis, embolic disease, dissection, and fibromuscular disease.Chronic kidney disease is the most common manifestation of ischaemic nephropathy, but hypertension, flash pulmonary oedema, sensitivity to angiotensin blockade, and sensitivity of glomerular filtration rate to blood pressure reduction are all possible manifestations of occlusive diseases of the renal artery or its branches. Proteinuria may also occur.This chapter describes these clinical features and the outcomes of ischaemic nephropathy. It goes on to discuss the haemodynamics and mechanisms and what we understand of the pathophysiology of the condition.

Care of the post-transplant kidney patient is complex and requires multidisciplinary team working. Careful attention is paid to haemodynamics, fluid balance, microbiology, drug prescription, and patient instruction. Delays in, or reduction of, graft function should be investigated and treated immediately to ensure long-term graft survival. Because complications do occur, they must be recognized early and dealt with promptly. The nature of the transplant operation and the need for immunosuppression mean that the complications differ from those of ordinary general surgical patients, and so require specialist medical, microbiological, or radiological input with a narrower time window for correction. This chapter covers the immediate postoperative care of the renal transplant recipient both as an inpatient and the early period as an outpatient, highlighting the potential complications and their management.

Evolution has developed a complex cardiovascular system, the analysis of which involves many physical disciplines. Specifically, cardiovascular function critically depends on the proper interaction between blood and the vessel wall, such that haemodynamics-based biomechanical factors are a common denominator of cardiovascular pathologies. This chapter reviews biomechanics-related physical processes in the vessel. Specifically, mechanical load transition mechanisms in blood and the vessel wall, blood-wall interaction phenomena, as well as simple analytical solutions to Newton’s second law of mechanics are discussed. Albeit that such simple analytical relations are very useful when exploring physical processes in the vasculature, their application is limited and cardiovascular analysis often requires more advanced computational methods so as to draw conclusions from Newton’s law. Most important, the proper application of either simple or more advanced physical models requires close interaction between engineering and medical disciplines.

Prevention of acute renal failure 312Diagnosis of acute renal failure 314Acute kidney injury (AKI) often complicates the course of critical illness and was previously considered as a marker rather than a cause of adverse outcomes, it is independently associated with an increase in both morbidity and mortality. The major causes of AKI in the ICU include hypoperfusion, sepsis and direct nephrotoxicity, with the common aetiology believed to be a change in intrarenal haemodynamics with resultant acute tubular dysfunction and oxidant stress. Treatment of established acute renal failure in the ICU entails the use of RRT by means of various modalities, although this therapy itself carries an inherent morbidity and risk. Therefore, preventing or minimizing renal injury should confer a benefit to patients. Consequently, several pharmacological interventions have been tried to treat AKI. These interventions can be separated into measures influencing renal perfusion and measures modulating intrarenal pathophysiology....

Echocardiography can provide rapid and accurate assessment of cardiac morphology and haemodynamics under stressful conditions in the emergency room (ER). Using this information, critical decisions regarding management of cardiovascular emergencies and the critically ill are made. To avoid potentially catastrophic errors with medicolegal consequences, adequate education and experience in echocardiography and cardiology are required and teamwork is encouraged. In addition, emergency cases must be well documented and this documentation stored and retrievable. Transthoracic echocardiography is the main source of the information in the emergency setting, while transoesophageal, contrast, and stress echocardiography are used when needed and in special circumstances.In this chapter, the principles, practice, and specific considerations related to echocardiography in the ER are discussed and a brief overview of echocardiographic assessment in cardiac emergencies is provided. Detailed information regarding echocardiographic features of particular cardiovascular diseases and conditions that may be presented to the emergency physician in the ER can be found elsewhere in this book in the related chapters.

Streszczenie:

The endothelins (ETs) are a family of related peptides of which ET-1 is the most powerful endogenous vasoconstrictor and the predominant isoform in the cardiovascular and renal systems. The ET system has been widely implicated in both cardiovascular disease and chronic kidney disease (CKD). ET-1 contributes to the pathogenesis and maintenance of hypertension and arterial stiffness, as well endothelial dysfunction and atherosclerosis. By reversal of these effects, ET antagonists, particularly those that block ETA receptors, may reduce cardiovascular risk. In CKD patients, antagonism of the ET system may be of benefit in improving renal haemodynamics and reducing proteinuria, effects seen both in animal models and in some human studies. Data suggest a synergistic role for ET receptor antagonists with angiotensin-converting enzyme inhibitors in lowering blood pressure, reducing proteinuria, and in animal models in slowing CKD progression. However, in clinical trials, fluid retention or cardiac failure has caused concern and these agents are not yet ready for general use for risk reduction in CKD.

Right ventricular (RV) performance plays an important role in the morbidity and mortality of patients with left ventricular dysfunction, congenital heart disease, and pulmonary hypertension. Assessment of RV size, function, and haemodynamics has been challenging because of its complex geometry. Conventional two-dimensional echocardiography is the modality of choice for assessment of RV function in clinical practice. Recent developments in echocardiography have provided several new techniques for assessment of RV dimensions and function, include tissue Doppler imaging, speckle-tracking imaging, and volumetric three-dimensional imaging. However, specific training, expensive dedicated equipment, and extensive clinical validation are still required. Doppler methods interrogating tricuspid inflow and pulmonary artery flow velocities, which are influenced by changes in pre- and afterload conditions, may not provide robust prognostic information for clinical decision-making. This chapter addresses the role of the various echocardiographic modalities used to assess the RV and pulmonary circulation. Special emphasis has been placed on technical considerations, limitations, and pitfalls of image acquisition and analysis.

After computed tomography and computed tomography angiography or magnetic resonance imaging and magnetic resonance angiography at admission, ultrasound is the most important diagnostic tool to confirm angiographic findings and to closely follow-up patients until the clinical situation has stabilized. Thrombolysis and interventional therapy have given transcranial ultrasound a very important role in bedside monitoring of occlusions, collaterals, cerebral haemodynamics, and vasoreactivity. Detection of flow changes in sickle cell disease, circulating emboli, and right-to-left shunts may guide treatment decisions. Sonothrombolysis and targeted drug delivery are today’s research projects for acute treatment by ultrasound. Extracranial cerebrovascular ultrasound is an ‘all-round’ diagnostic tool modifying angiographic results, showing minor arterial wall disease, plaques, and plaque instability. Microembolic signals during scanning may contribute to finding the cause of stroke. In stroke prevention, ultrasound delivers the possibility for staging of arteries and improving targeted intervention. Ultrasound images may also serve as educational tools for patients to underline the need for continuous medical treatment and lifestyle changes, and may improve compliance.

Streszczenie:

Corrosive poisoning, typically with household chemicals, is a common problem in children and adults. As ingestion by adults is often intentional, they are usually associated with larger volumes of strong agents and have the potential to create more severe injury than that observed in the accidental ingestions commonly seen in children. The goal of acute care in these cases is to stabilize acute compromise of haemodynamics and to ensure patency of the injured airway. Blind placement of nasogastric tubes and attempts at dilution or neutralization of the ingested chemical are potentially hazardous and should be avoided. Early identification of oesophageal or gastric perforation by clinical evaluation and radiological testing will lead to early and appropriate surgical interventions for these complications. The primary focus after initial stabilization is to evaluate the extent of gastrointestinal injury by early endoscopy. The application of a standardized score to grade the injury allows risk stratification, the planning of nutritional support and referral for appropriate management of the chronic sequelae of scarring and stenosis of the injured gastrointestinal tract. No specific medical therapy can attenuate the extent of damage acutely nor alter the progression of chronic changes.
