The prevalence of pulmonary artery catheter (PAC) entrapment in open-heart surgery is scarce with a prevalence rate of 0.065%. Challenges in managing such cases lie particularly in choosing the modalities (chest roentgenogram, fluoroscopy, and transesophageal echocardiography) to accurately identify the anatomic location and cause of entrapment. In this case, we report a 42-year-old man who underwent mitral valve replacement with PAC entrapment discovered on postoperative day 2 and subsequently underwent retrieval after re-sternotomy...

Coronary surgery performed on an arrested heart, using one internal mammary artery and a saphenous vein carries two main potential drawbacks: the known failure rate of vein grafts and the relatively high rate of neurologic injury. To address these concerns, we describe a technique that achieves complete revascularization without manipulating the ascending aorta (anaortic, off-pump) and utilizing total arterial grafts. All patients undergo thorough preoperative investigation, including bilateral carotid, vertebral and subclavian artery Duplex ultrasounds...

Neuroendocrine tumours are a rare malignancy, which can be complicated by a carcinoid syndrome and, in more rare cases, also valve destruction. The correct timing for surgical repair remains unknown. We report the first-in-men exercise cardiac magnetic resonance imaging with pulmonary artery catheter measurements in order to better understand the haemodynamic impact of isolated tricuspid valve insufficiency in a low symptomatic patient. Not pressure but volume overload is the key factor in the development of symptoms, as long as the right ventricular function is intact...

Background: Considerable controversy remains about how much oxygen patients should receive during surgery. The 2016 World Health Organization (WHO) guidelines recommend that intubated patients receive a fractional inspired oxygen concentration (FIO2 ) of 0.8 throughout abdominal surgery to reduce the risk of surgical site infection. However, this recommendation has been widely criticised by anaesthetists and evidence from other clinical contexts has suggested that giving a high concentration of oxygen might worsen patient outcomes...

Taking arterial blood gases (ABG) is an essential part of the diagnosis and management of critically ill patients. An arterial blood sample is collected from an artery, primarily to determine the ABGs. Health professionals should only undertake this if the procedure is in the legal scope of practice for their profession in their country, and they have demonstrated skilled, proficient, safe practice after formal training. Blood samples can be obtained via an arterial catheter inserted into an artery or percutaneously by using a needle to directly puncture into the artery...

OBJECTIVES: This study assessed the efficacy of oral consumption of N-acetyl cysteine (NAC) and melatonin (ML) in reducing early reperfusion injury and acute oxidative stress in patients undergoing coronary artery bypass grafting (CABG) with respect to the measurements of cardiac troponin I, lactate, malondealdehyde (MDA), and tumor necrosis factor-α (TNF-α) levels in the blood. METHODS: This study was a randomized, open-label, placebo-controlled trial. Eighty eight patients, aged between 39 to 76 years and eligible for CABG, were recruited and randomly assigned into 3 intervention groups through a simple randomization method and underwent CABG surgery...

PURPOSE: Aortic occlusion (AO) increases proximal perfusion and may improve rates of return of spontaneous circulation (ROSC). The objective of this study was to investigate the hemodynamic effects of cardiopulmonary resuscitation (CPR) and AO by REBOA on patients in traumatic cardiac arrest. METHODS: Patients admitted between February 2013 and May 2017 at a tertiary center who suffered traumatic arrest, had an arterial line placed during resuscitation, and received CPR and REBOA which were included...

Arterial thrombosis is increasingly recognized in children and is mostly related to the presence of an arterial catheter or an ischemic stroke. Treatment of children with arterial thrombosis varies widely and consists on the administration of the common available anticoagulant und antiplatelet drugs. No evidence-based guidelines are available so far to prefer one treatment approach to another. Data in adults indicate that understanding the pathomechanism and composition of arterial thrombosis is crucial for choosing the most efficient and safe antithrombotic drug...

PURPOSE: Veno-arterial extracorporeal membrane oxygenation (VA-ECMO) is increasingly used to support conventional unsuccessful resuscitation and it is mandatory to rapidly initiate invasive hemodynamic monitoring, as soon as ECPR therapy is commenced. Commonly, this is achieved by establishing an additional arterial line via the right radial artery for invasive blood pressure measurement, but this can be challenging and risky on the one hand and might lead to erroneous measurements on the other hand...

Manual palpation of pulses is unreliable in detecting pulsatile flow in human participants, complicating the assessment of return of spontaneous circulation after cardiac arrest. Ultrasound may offer an alternative. This study's objective was to investigate whether return of pulsatile flow in humans can be reliably assessed by common carotid artery ultrasound. We conducted a single-blinded randomised study of common carotid artery ultrasound using 20 cardiopulmonary bypass patients to model the return of pulsatile flow...

HELLP (hemolysis elevated liver enzyme low platelet) syndrome is associated with hypertension, inflammation, oxidative stress and endothelial activation. The objective of this study was to determine if oxygen scavenging or endothelin A receptor antagonism improved hypertension and oxidative stress. sFlt-1 and sEndoglin were infused via mini-osmotic pump into normal pregnant rats (NP) on gestational day 12 to create HELLP syndrome. On gestational day 18 arterial catheters were inserted and on gestational day 19 mean arterial pressure was analyzed in rats; serum, urine and tissues were collected for molecular analysis...

STUDY DESIGN: Retrospective cohort study. OBJECTIVE: To demonstrate the relationship between perioperative use of catheters and the incidence of surgical site infection (SSI) after cervical spine surgery, after adjusting for patient's age, severity of comorbidity, surgical approach, and use of instrumentation. SUMMARY OF BACKGROUND DATA: Although the association between SSI and the use of arterial catheters (ACs) or central venous catheters (CVCs) is established in cardiac surgery, the relation in the cervical spine was not well elucidated...

This study assesses positional changes in cardiac power output and stroke work compared with classic hemodynamic variables, measured before and after elective coronary artery bypass graft surgery. The hypothesis was that cardiac power output was altered in relation to cardiac stunning. The study is a retrospective analysis of data from two previous studies performed in a tertiary care university hospital. Thirty-six patients scheduled for elective coronary artery bypass graft surgery, with relatively preserved left ventricular function, were included...

Since there were a few articles to report the treatment of severe pulmonary vasoconstriction induced by protamine in cardiac surgery, we described the use of epoprostenol to reverse this condition.A total of 5 cases of severe pulmonary vasoconstriction induced by protamine in cardiac surgery were reviewed. The demographic, clinical data and treatment process were obtained. All the patients were followed up.Severe pulmonary vasoconstriction was occurred 4 to 10 minutes after protamine infusion. The primary sign was sudden hypotension, the pulmonary artery pressure was increased gradually, the arterial oxygen partial pressure was decreased in all the patients...

This paper presents a novel multiple measurement information fusion approach to the estimation of cardiovascular risk predictors from non-invasive pulse volume waveforms measured at the body's diametric (arm and ankle) locations. Leveraging the fact that diametric pulse volume waveforms originate from the common central pulse waveform, the approach estimates cardiovascular risk predictors in three steps by: (1) deriving lumped-parameter models of the central-diametric arterial lines from diametric pulse volume waveforms, (2) estimating central blood pressure waveform by analyzing the diametric pulse volume waveforms using the derived arterial line models, and (3) estimating cardiovascular risk predictors (including central systolic and pulse pressures, pulse pressure amplification, and pulse transit time) from the arterial line models and central blood pressure waveform in conjunction with the diametric pulse volume waveforms...
