A contrast echocardiographic technique using peripheral vein injections for the detection and localization of intracardiac right-to-left shunting is described. Fifty children underwent cardiac catheterization and peripheral contrast echocardiographic studies. The site, degree, and direction of shunting were established at catheterization by oximetry, indicator dilution analysis and/or angiograp...

purpose: to investigate aqueous humor nitric oxide (no) levels in patients with branch retinal vein occlusion (brvo) and central retinal vein occlusion (crvo) and to compare these with age-matched controls. methods: eight consecutive patients with brvo and 16 patients with crvo were included in this study. aqueous humor specimens were obtained within 21 days of diagnosis. samples of aqueous hum...

Bacterial counts were made of catheter insertion site and of catheter tips to help determine risk factors associated with catheterization of the jugular and subclavian veins. Among the 116 patients included in this study, 69% had central venous catheters (CVC) in the subclavian vein. Seven or more days catheterization (p=0.001) and > or =3 invasive devices (p=0.01) were infection risk factors a...

Objective: To evaluate the isolated pathogens in patients who underwent central venous catheterization due to cardiovascular procedures. Materials and Methods: Patients were monitored daily for development of catheter related infections. Between April 2017 July 2019, exhibited infection symptoms like discharge, fever, pain, lymphadenopathy itching after included this retrospective study. Patien...

A 77-year-old man was admitted with multiple co-morbidities including cerebral infarction, postoperative ossification of the cervical posterior longitudinal ligament, sick sinus syndrome with a cardiac pacemaker inserted from the right subclavian vein, and panperitonitis due to a complicated gastrostomy catheter exchange. The patient developed a critical and rare complication of central venous ...

PURPOSE To develop a clinically relevant porcine model for the study of hepatic metabolism of drugs by means of hepatic vein catheterization. MATERIALS AND METHODS review of literature and elaboration of a hypothesis, design of an experimental method. RESULTS recent clinical studies were conducted by withdrawing cirrhotic patients' blood from right hepatic vein during hepatic vein pressure ...

The subclavian vein is the preferred site for central venous catheter insertion because of its several advantages. Infraclavicular commonly used approach while supraclavicular less popular catheterizing vein. aim study was to compare and infraclavicular catheterization in terms number attempts, success rate, access time record complications associated with procedure. In this study, 120 patients...

BACKGROUND We report a case of surgical central venous port system implantation using Seldinger's technique with a life-threatening mediastinal hematoma due to the perforation of the superior vena cava. CASE REPORT A 68-year-old woman was admitted to our institution for port implantation. Open access to the cephalic vein and 2 punctures of the right subclavian vein were unsuccessful. Finally,...

Objective: We studied finder needle use in Internal Jugular Vein (IJV) catheterization and complications rate in adult cardiac surgery. Methods: A prospective study was carried out for 3 month period from august to November 2007 and all patients older than 18 years who underwent elective cardiac surgery were studied. Data were collected about using finder needle, patient position, success rate,...

introduction: finding the probable governing pattern of peep and cvp changes is an area of interest for in-charge physicians and researchers. therefore, the present study was designed with the aim of evaluating the relationship between the mentioned pressures. methods: in this quasi-experimental study, patients under mechanical ventilation were evaluated with the aim of assessing the effect of ...
