PURPOSE OF THE STUDY: To analyze complications of the pulmonary artery catheterization in patients with blood diseases. MATERIALS AND METHODS: 93 cases of pulmonary artery catheterization in patients with blood diseases were included in the retrospective study. RESULTS: Indications for pulmonary artery catheterization were septic shock (78.5%) and acute respiratory failure (21.5%). In 31 cases (33.3%) pulmonary artery catheterization was performed in conditions of agranulocytosis and in 81 cases (87%) in conditions of thrombocytopenia (platelets median 43 x 109 per liter minimal 7 x 109, maximal 150 x 109 per liter)...

Preservation of cardiac output (CO) and pulmonary artery pressure (PAP) is vital to maintaining tissue oxygenation in sepsis. This feasibility study tested the hypothesis that therapeutic intra-thoracic pressure regulation (tIPR), delivered with a novel device, was designed to non-invasively enhance venous return by creating sub-atmospheric intra-thoracic pressure during the expiratory phase of mechanical ventilation, improves CO without fluid resuscitation in a porcine E. coli peritonitis model of sepsis. Seven pigs were intubated, anaesthetized and instrumented with a Swan-Ganz and femoral artery catheter...

A prospective, observational study was undertaken to determine the frequency of troponin I elevation and the incidence of pre-existing cardiac disease in patients with severe sepsis and septic shock, and to determine their relationship to mortality. The setting was the surgical intensive care unit of a tertiary care medical centre. Sixty-six consecutive patients admitted with severe sepsis or septic shock requiring pulmonary artery catheterisation for haemodynamic monitoring were studied. Measurement of troponin I was done at the time of pulmonary artery catheterisation and every six to eight hours if there was ongoing tachycardia, hypotension or arrhythmias requiring treatment...

The indication for the use of the pulmonary artery catheter (PAC) in high-risk patients is still a matter of discussion. Observational studies suggested that the use of the PAC did not result in decreased mortality but may even lead to increased mortality and morbidity. Therefore, a number of randomized controlled trials have been performed throughout recent years in patients suffering from sepsis/ARDS, congestive heart failure, multi-organ failure and those undergoing high-risk non-cardiac surgery. The majority of recent randomized studies failed to demonstrate any benefit of the PAC with respect to mortality and morbidity...

BACKGROUND: Depression of myocardial contractility occurs in septic shock. METHODS: Fourteen pigs were instrumented to measure cardiopulmonary dynamics after a challenge of Escherichia coli endotoxin (lipopolysaccharide endotoxin, LPS). A volumetric Swan-Ganz catheter was placed via the jugular vein, and a carotid arterial line was placed into the aortic root. Eight pigs received LPS alone and six pigs received tumor necrosis factor monoclonal antibody (TNF MAb) 15 minutes before the administration of LPS...

REVIEW
J Rello, P Jubert, M E Esandi, J Vallés
In our experience, the incidence and pathogenesis of colonization may vary in different types of catheters. Arterial, Swan-Ganz, and hemodialysis catheters are good examples of this problem. This observation has implications for diagnosis, and the best method for each type of catheter may not be the same. In our opinion, laboratory diagnosis in daily practice should be limited to external surface cultures of the tip of intravascular catheters. Intraluminal cultures should be limited to research purposes, except in catheters used for parenteral nutrition or hemodialysis...

Invasive hemodynamic monitoring has become standard in the management of aneurysmal subarachnoid hemorrhage. This study is a retrospective analysis of 630 Swan-Ganz catheters placed in 184 patients with aneurysmal subarachnoid hemorrhage. Evaluation of complications demonstrated a 13% incidence of catheter-related sepsis (81 of 630 catheters), a 2% incidence of congestive heart failure (13 of 630 catheters), a 1.3% incidence of subclavian vein thrombosis (8 of 630 catheters), a 1% incidence of pneumothorax (6 of 630 catheters), and a 0% incidence of pulmonary artery rupture...

Patients with cardiovascular disease commonly present with problems requiring surgical treatment. They are more vulnerable than patients without cardiovascular disease to the cardiovascular stresses associated with general anesthesia and surgery--hypotension, hypoxemia, sepsis, and thromboembolism. Their risk of morbidity and mortality is higher. Certain clinical factors have a profound impact on the patient's likelihood of serious cardiac complications or death: Overt heart failure, recent myocardial infarction, and cardiac arrhythmias are the most worrisome...

Problems of infections in the intensive care unit (ICU) center on patients admitted because of sepsis, patients with compromised host defenses and patients subject to invasive procedures. The mortality rate in septic shock is high, 47% in our own study. Escherichia coli was found in half the cases. Multiple organ failure is often the common denominator in patients with sepsis. Hypovolaemia and low serum proteins make the patients more susceptible to infections. Typical ICU procedure, i.e. central venous catheters, arterial lines, Swan-Ganz catheters, endotracheal tubes and urinary catheters violate natural bacterial defence barriers and may be a source of infection...

Acute respiratory failure (ARF) related to sepsis continues to have a high mortality and uncertain pathogenesis. With a reproducible live Pseudomonas aeruginosa infusion pig model, the gas exchange, hemodynamics, and pulmonary clearance of this organism were compared with live Staphylococcus aureus and Escherichia coli. Lightly anesthetized, male, mixed-breed pigs, 15-30 kg, were intubated, allowed to breathe spontaneously, and had femoral artery, central venous, and Swan-Ganz catheterization through cutdowns...

Spontaneous rupture of the common bile duct is rare, but may result from increased intraductal pressure with associated calculous erosion and necrosis of the bile duct wall secondary to thrombosis. Two cases are reported; one clearly related to calculous erosion and the other unexplained. Survival depends on early diagnosis. Aggressive supportive therapy, including Swan-Ganz catheter, intensive care unit monitoring, and appropriate antibiotics, are mandatory. Only with early operation to alleviate sepsis and decompression of the biliary system can better survival be expected...

Right atrial pressure (RAP) can be used as a guide to fluid therapy in critical care settings. RAP and pulmonary capillary wedge pressure (WP) were measured in 27 septic patients without cardiac disease and on mechanical ventilation. An r of .61 was obtained with a regression line defined by the equation WP = 7.38 + (0.53 x RAP) +/- 3.15. However, a large SD of data points can invalidate the clinical usefulness of this equation. The reliability of various RAP interval values in predicting optimal WP was then studied in these patients...

The aim of this study was to investigate the oxygenation of the gastrointestinal tract mucosa using indirect pH measurements in a porcine septic model (intravenous infusion of live E. coli). By means of intraluminally placed balloon catheters (Tonomitior) permeable to CO2, intramucosal pH (pHi) was calculated using the Henderson-Hasselbalch equation. Cardiopulmonary hemodynamics and portal blood flow were measured using Swan-Ganz catheters. Samples were taken from the gastrointestinal tract for histological examination...

We analyzed 8 cases of meningococcal septic shock diagnosed in a three year period. The age varied from 20 months to 10 years (mean: 4.8 years). Two patients died. Every child was monitored with a Swan-Ganz catheter 5 F or 7F, placed on by puncture of internal jugular or subclavicular veins. Of this hemodynamic study, we can conclude that in septic shock, there is a myocardial depression, that persist for several days, and improves with dopamine and dobutamine. In addition to this, in sepsis exists a pulmonary hypertension that makes worse the prognosis...
