pulmonary artery catheter

Matthias Hansen
Advanced hemodynamic monitoring is necessary for adequate management of high-risk patients or patients with derangement of circulation. Studies demonstrate a benefit of early goal directed therapy in unstable cardiopulmonary situations. In these days we have different possibilities of minimally invasive or invasive hemodynamic monitoring. Minimally invasive measurements like pulse conture analysis or pulse wave analysis being less accurate under some circumstances, however only an artery catheter is needed for cardiac output monitoring...

The Melody® transcatheter pulmonary valve system was developed for placement within right ventricle-to-pulmonary artery conduits in patients with CHD for treatment of stenosis or regurgitation, providing an alternative to open-heart surgery. Abnormal systemic venous connections altering the catheter course to the right ventricle-to-pulmonary artery conduit may present a challenge to Melody® valve implantation. We present two such cases, in which the Melody® valve was successfully implanted in teenage patients with congenitally corrected transposition of the great arteries after Senning atrial switch operation...

BACKGROUND: Intrapulmonary thermodilution technique using a pulmonary artery catheter is widely used for measuring cardiac output (CO) in patients undergoing liver transplantation. However, its invasiveness and associated complications have led to an interest in less invasive modalities. Thus, we aimed to evaluate whether the new calibrated pulse-wave analysis method monitoring (VolumeViewTM/EV1000TM) is interchangeable with intrapulmonary thermodilution technique. METHODS: Twenty-eight patients undergoing living donor liver transplantation were enrolled in this prospective observational study...

PURPOSE: To describe all post-insertion complications involving most used intravascular access, and to determine whether the use of a new-generation transparent dressing (3M™ IV Advanced) might reduce their number and impact on ICU patient outcomes. METHODS: Patients older than 18, with an expected length of stay ≥48 h and requiring at least one central venous catheter (CVC), arterial catheter (AC), haemodialysis catheter (HDC), pulmonary arterial catheters (PAC) or peripheral venous catheter (PVC) were randomized into two groups: a new-generation transparent dressing, or the hospital's classical transparent dressing, and were followed daily for any infectious and non-infectious complications...

BACKGROUND: We sought to estimate the efficacy and safety outcomes of catheter-directed treatment (CDT) for patients with acute pulmonary embolism (PE). METHODS: We searched SCOPUS for studies reporting outcomes after CDT for acute PE. Studies were categorized in three groups for analyses due to heterogeneity in the classification of acute PE: 1) patients with PE causing right ventricular dysfunction and haemodynamic instability: unstable haemodynamic status, 2) patients with PE causing right ventricular dysfunction where study outcomes were not stratified by haemodynamic status: stable and unstable haemodynamic status, and 3) patients with PE causing right ventricular dysfunction who remained haemodynamically stable: stable haemodynamic status...

A reliable estimation of cardiac preload is helpful in the management of severe circulatory dysfunction. The estimation of cardiac preload has evolved from nuclear angiography, pulmonary artery catheterization to echocardiography, and transpulmonary thermodilution (TPTD). Global end-diastolic volume (GEDV) is the combined end-diastolic volumes of all the four cardiac chambers. GEDV has been demonstrated to be a reliable preload marker in comparison with traditionally used pulmonary artery catheter-derived pressure preload parameters...

Hemodynamic monitoring has long formed the cornerstone of heart failure (HF) and pulmonary hypertension diagnosis and management. We review the long history of invasive hemodynamic monitors initially using pulmonary artery (PA) pressure catheters in the hospital setting, to evaluating the utility of a number of implantable devices that can allow for ambulatory determination of intracardiac pressures. Although the use of indwelling PA catheters has fallen out of favor in a number of settings, implantable devices have afforded clinicians an opportunity for objective determination of a patient's volume status and pulmonary pressures...

BACKGROUND: In patients with severe pulmonary arterial hypertension, subcutaneous or catheter-based intravenous application of prostanoids carries a risk of local side effects or systemic infections, which limits their use and acceptance. Recently, a fully implantable pump for continuous application of intravenous treprostinil was approved in Germany. However, surgery is a major risk for patients with severe pulmonary arterial hypertension. The purpose of this study was to investigate the safety of a fully implantable pump inserted under local or general anesthesia in patients with severe pulmonary hypertension...

Recent advances in anticancer chemotherapy have resulted in an increase in the number of patients requiring a central venous port catheter, and the incidence of catheter pinch-off syndrome has been increasing. Catheter pinch-off syndrome is a rare and unusual complication. It is difficult to retrieve dislodged catheters from the pulmonary artery, especially if the catheter is stuck to the peripheral pulmonary artery. We herein describe the successful removal of a catheter stuck in the pulmonary artery with a stepwise approach...

OBJECTIVES: This study aimed to assess the short-term respiratory tolerance and haemodynamic efficiency of low-volume resuscitation with hypertonic saline and hydroxyethylstarch (HS/HES) in a pig model of lung contusion and controlled haemorrhagic shock. We hypothesised that a low-volume of HS/HES after haemorrhagic shock didn't impact contused lungs in terms of extravascular lung water 3hours after trauma. METHODS: A lung contusion resulting from blunt chest trauma was induced in 28 anaesthetised female pigs with five bolt shots to the right thoracic cage, followed by haemorrhagic shock and fluid resuscitation...

Our objective was to investigate the predictive value of fractional nitric oxide (NO) concentration in exhaled breath (FeNO) and aerobic capacity (peak VO2 ) for postoperative sepsis in liver transplantation candidates. Patients were identified and charts of all consecutive patients were prospectively reviewed. Bacterial sepsis represented the commonest postoperative complications (30%), which was attributed to peritonitis, pneumonia, and catheter-related infections. Preoperative FeNO and peak VO2 values were lower in patients with postoperative sepsis...

PURPOSE: Pleural pressure measured with esophageal balloon catheters (Peso) can guide ventilator management and help with the interpretation of hemodynamic measurements, but these catheters are not readily available or easy to use. We tested the utility of an inexpensive, fluid-filled esophageal catheter (Peso) by comparing respiratory-induced changes in pulmonary artery occlusion (Ppao), central venous (CVP), and Peso pressures. METHODS: We studied 30 patients undergoing elective cardiac surgery who had pulmonary artery and esophageal catheters in place...
