The Swan-Ganz catheter, also known as a pulmonary artery catheter, is a specialized catheter used to monitor a patient's hemodynamics. It is inserted into the internal jugular or subclavian vein and threaded through the heart into the pulmonary artery. This allows direct measurement of pressures in the right atrium, right ventricle, pulmonary artery, and indirect measurement of left-sided pressures. The catheter is useful for diagnosis and management of conditions affecting heart function or pulmonary circulation. However, randomized controlled trials found no improvement in outcomes with its use and increased risks, so the catheter's benefits must be weighed against risks for each individual patient.
Pulmonary artery-catheter2
Pulmonary artery catheterization is a technique used to monitor cardiac pressures and output. The catheter is inserted into the internal jugular, subclavian, or femoral veins and threaded into the pulmonary artery. It has four lumens to measure pressures in the right atrium, right ventricle, pulmonary artery, and by wedging in a pulmonary capillary. Indications include major surgery, heart disease, or hemodynamic instability. Complications include arrhythmias, thromboembolism, and pulmonary artery rupture. Abnormal waveforms provide information on conditions like mitral regurgitation. Controversy exists on outcomes, with some studies finding increased risk while others found no effect or benefit in selected patients.

Hemodynamic monitorig
Hemodynamic monitoring involves assessing the movement of blood through the cardiovascular system. There are non-invasive and invasive methods, with the pulmonary artery catheter allowing for direct measurement of central venous pressure, pulmonary artery pressure, pulmonary artery occlusion pressure, cardiac output, and mixed venous oxygen saturation. Placement of the pulmonary artery catheter carries risks of complications but provides valuable hemodynamic data that can guide diagnosis and management of critically ill patients.
Hemodynamic Monitoring
Hemodynamic monitoring involves the invasive measurement of pressures within the heart and vessels to assess cardiovascular function and tissue perfusion. It utilizes a catheter connected to a transducer and monitor. Catheters can be placed in the pulmonary artery via the jugular or subclavian vein, in the right atrium, or in arteries like the radial or femoral. This allows the direct measurement of pressures in these areas to guide treatment for issues like shock. Complications can include infections, arrhythmias, or embolisms, so the insertion site must be carefully monitored.

Rigid bronchoscopy requires general anesthesia or IV sedation and involves risks of airway obstruction and desaturation that require close monitoring. Mediastinoscopy carries risks of hemorrhage, nerve injury, and pneumothorax that may require emergent intervention. Endobronchial ultrasound-guided biopsy is typically performed with conscious sedation using topical anesthesia and sedatives administered through a bronchoscope.
Deep Vein Thrombosis
This document provides information on deep vein thrombosis (DVT), including its definition, risk factors, diagnosis, and treatment. Some key points:
- DVT is a blood clot (thrombus) that forms in a deep vein, usually in the legs. It can dislodge and cause a pulmonary embolism if it reaches the lungs.
- Risk factors for DVT include immobility, surgery, older age, and genetic or acquired hypercoagulable states. The Virchow's triad of factors contributing to clot formation are venous stasis, endothelial injury, and hypercoagulability.
- Diagnosis involves a clinical assessment, D-dimer testing

Acute respiratory distress syndrome
This document provides an overview of Acute Respiratory Distress Syndrome (ARDS). It discusses the epidemiology, causes, clinical course and features, diagnostic criteria, investigations and management of ARDS. The key points are: ARDS affects approximately 10% of ICU patients annually and has a mortality rate of around 30%; it is caused by direct or indirect lung injury and progresses through exudative, proliferative and fibrotic phases; diagnosis is based on acute onset hypoxemia, bilateral opacities on chest imaging and low oxygen levels; management focuses on treating the underlying cause, lung protective ventilation with low tidal volumes, PEEP and prone positioning if severe. With treatment, most ARDS survivors recover lung function within 6-

ABDOMINAL TRAUMA in pediatrics part one.
Abdominal trauma in pediatrics refers to injuries or damage to the abdominal organs in children. It can occur due to various causes such as falls, motor vehicle accidents, sports-related injuries, and physical abuse. Children are more vulnerable to abdominal trauma due to their unique anatomical and physiological characteristics. Signs and symptoms include abdominal pain, tenderness, distension, vomiting, and signs of shock. Diagnosis involves physical examination, imaging studies, and laboratory tests. Management depends on the severity and may involve conservative treatment or surgical intervention. Prevention is crucial in reducing the incidence of abdominal trauma in children.

Overall life span (LS) was 1671.7±1721.6 days and cumulative 5YS reached 62.4%, 10 years – 50.4%, 20 years – 44.6%. 94 LCP lived more than 5 years without cancer (LS=2958.6±1723.6 days), 22 – more than 10 years (LS=5571±1841.8 days). 67 LCP died because of LC (LS=471.9±344 days). AT significantly improved 5YS (68% vs. 53.7%) (P=0.028 by log-rank test). Cox modeling displayed that 5YS of LCP significantly depended on: N0-N12, T3-4, blood cell circuit, cell ratio factors (ratio between cancer cells-CC and blood cells subpopulations), LC cell dynamics, recalcification time, heparin tolerance, prothrombin index, protein, AT, procedure type (P=0.000-0.031). Neural networks, genetic algorithm selection and bootstrap simulation revealed relationships between 5YS and N0-12 (rank=1), thrombocytes/CC (rank=2), segmented neutrophils/CC (3), eosinophils/CC (4), erythrocytes/CC (5), healthy cells/CC (6), lymphocytes/CC (7), stick neutrophils/CC (8), leucocytes/CC (9), monocytes/CC (10). Correct prediction of 5YS was 100% by neural networks computing (error=0.000; area under ROC curve=1.0).
Novas diretrizes da OMS para os cuidados perinatais de mais qualidade
Novas diretrizes da OMS para os cuidados perinatais de mais qualidadeProf. Marcus Renato de Carvalho
Recomendações da OMS sobre cuidados maternos e neonatais para uma experiência pós-natal positiva.
Em consonância com os ODS – Objetivos do Desenvolvimento Sustentável e a Estratégia Global para a Saúde das Mulheres, Crianças e Adolescentes, e aplicando uma abordagem baseada nos direitos humanos, os esforços de cuidados pós-natais devem expandir-se para além da cobertura e da simples sobrevivência, de modo a incluir cuidados de qualidade.
Estas diretrizes visam melhorar a qualidade dos cuidados pós-natais essenciais e de rotina prestados às mulheres e aos recém-nascidos, com o objetivo final de melhorar a saúde e o bem-estar materno e neonatal.
Uma “experiência pós-natal positiva” é um resultado importante para todas as mulheres que dão à luz e para os seus recém-nascidos, estabelecendo as bases para a melhoria da saúde e do bem-estar a curto e longo prazo. Uma experiência pós-natal positiva é definida como aquela em que as mulheres, pessoas que gestam, os recém-nascidos, os casais, os pais, os cuidadores e as famílias recebem informação consistente, garantia e apoio de profissionais de saúde motivados; e onde um sistema de saúde flexível e com recursos reconheça as necessidades das mulheres e dos bebês e respeite o seu contexto cultural.
Estas diretrizes consolidadas apresentam algumas recomendações novas e já bem fundamentadas sobre cuidados pós-natais de rotina para mulheres e neonatos que recebem cuidados no pós-parto em unidades de saúde ou na comunidade, independentemente dos recursos disponíveis.
É fornecido um conjunto abrangente de recomendações para cuidados durante o período puerperal, com ênfase nos cuidados essenciais que todas as mulheres e recém-nascidos devem receber, e com a devida atenção à qualidade dos cuidados; isto é, a entrega e a experiência do cuidado recebido. Estas diretrizes atualizam e ampliam as recomendações da OMS de 2014 sobre cuidados pós-natais da mãe e do recém-nascido e complementam as atuais diretrizes da OMS sobre a gestão de complicações pós-natais.
O estabelecimento da amamentação e o manejo das principais intercorrências é contemplada.
Recomendamos muito.
Vamos discutir essas recomendações no nosso curso de pós-graduação em Aleitamento no Instituto Ciclos.
