In Brazil, there are no data on the preferences of intensivists regarding hemodynamic monitoring methods. The present study aimed to identify the methods used by national intensivists, the hemodynamic variables they consider important, the regional differences, the reasons for choosing a particular method, and the use of protocols and continued training.
National intensivists were invited to answer an electronic questionnaire during three intensive care events and later, through the Associação de Medicina Intensiva Brasileira portal, between March and October 2009. Demographic data and aspects related to the respondent preferences regarding hemodynamic monitoring were researched.
In total, 211 professionals answered the questionnaire. Private hospitals showed higher availability of resources for hemodynamic monitoring than did public institutions. The pulmonary artery catheter was considered the most trusted by 56.9% of the respondents, followed by echocardiograms, at 22.3%. Cardiac output was considered the most important variable. Other variables also considered relevant were mixed/central venous oxygen saturation, pulmonary artery occlusion pressure, and right ventricular end-diastolic volume. Echocardiography was the most used method (64.5%), followed by pulmonary artery catheter (49.3%). Only half of respondents used treatment protocols, and 25% worked in continuing education programs in hemodynamic monitoring.
Hemodynamic monitoring has a greater availability in intensive care units of private institutions in Brazil. Echocardiography was the most used monitoring method, but the pulmonary artery catheter remains the most reliable. The implementation of treatment protocols and continuing education programs in hemodynamic monitoring in Brazil is still insufficient.

Pulmonary artery catheter is frequently used to monitor patients during liver transplantation. Recently developed less invasive methods for estimating cardiac output and pulmonary capillary wedge pressure together with the failure of randomized studies to demonstrate reduced mortality in pulmonary artery catheter-monitored patients, has restricted its applicability. Pulmonary artery rupture by pulmonary artery catheter is a rare, but dangerous complication. The purpose of this report is to describe a pulmonary artery rupture caused by monitorization with a pulmonary artery catheter, reviewing the clinical approach and discussing hemodynamic monitoring with the pulmonary artery catheter during liver transplantation. A 56 year old female patient, with cirrhosis caused by hepatitis C virus (MELD score 26) presented with acute hepatic encephalopathy. She was medicated and received a liver transplantation with invasive monitoring with a pulmonary artery catheter. In the first 24 hours after surgery, the patient presented with hemodynamic instability, low hematocrit, and cardiorespiratory arrest. After cardiopulmonary resuscitation, hemopericardium was diagnosed by transthoracic echocardiography and even after pericardiocentesis the patient developed recurrent hemopericardium. Pulmonary angiography did not disclose large vessellesions. The pulmonary artery rupture diagnosis was only made after sternotomy and direct lesion observation. Complications from use of pulmonary artery catheter are infrequent, however, due to their clinical severity, can cause high morbidity and mortality. A decreased use of pulmonary artery catheter reduced the number of complications observed. New clinical studies comparing pulmonary artery catheter with non-invasive methods for pulmonary capillary wedge pressure measurement must be conducted in liver transplantation.
