Perfusion Index and ultrasonography in the evaluation of infraclavicular block

Minerva Anestesiologica, 2019
It has been reported that noninvasive, objective tests are needed for determining the success of peripheral nerve blocks because conventional methods necessitate the cooperation of the patient. It is also known that the brachial plexus block causes vasodilatation and an increase in blood flow due to its sympathectomy effect.

Hepatic perfusion index and the evolution of liver metastases

Nuclear Medicine Communications, 1987
A total of 150 patients with primary carcinoma of the gastrointestinal tract had first-pass technetium colloid scintigraphy to estimate the hepatic perfusion index (HPI). Postoperative follow-up over 2-4 years shows that the HPI remains a sensitive method of detecting hepatic metastases, even in patients whose liver appeared normal at laparotomy.

Cerebral Perfusion Index

Journal of Neuroimaging, 1993
Single‐photon emission computed tomography (SPECT) and transcranial Doppler (TCD) ultrasound are of good prognostic value in acute stroke, and combined they may be an accurate way to determine a target group of patients with maximum therapeutic response.

Contrast‐Enhanced Doppler Perfusion Index

Journal of Ultrasound in Medicine, 2002
Objective. To assess the potential of the power Doppler signal intensity rate of enhancement due to contrast agent wash‐in for assessment of hepatic hemodynamics. Methods. With the use of standardized settings, power Doppler sonography was performed before and after administration of a contrast agent.

The serial changes of perfusion index in preterm infants with patent ductus arteriosus: is perfusion index clinically significant?

Minerva pediatrica, 2016
Perfusion Index (PI) which reflects the peripheral blood flow may help early detection and treatment decision of hemodynamically significant patent ductus arteriosus (hsPDA) in preterm infants. The present study is designed to analyze the usefulness of PI level in early detection of hsPDA in preterm infants.Preterm infants born before 36 gestational ...

Perfusion index in the preterm infant immediately after birth

Early Human Development, 2015
To evaluate PI in preterm infants during the first 10 min of life.An observational study was conducted in the delivery room on preterm infants (less than 32 week gestation). PI values were obtained from a pre ductal saturation probe placed on the right wrist.

The renal transplant perfusion index: reduction in the error and variability

European Journal of Nuclear Medicine, 1994
For 15 years, perfusion indices derived from scintigraphic studies have proved useful in the serial evaluation of renal transplants and they have recently been confirmed as being more sensitive than Doppler ultrasound as an indicator of vascular rejection and cyclosporin toxicity.

Perfusion Pressure and the Papillary Perfusion Index in a Non-glaucomatous population

1984
Le prove clinico-sperimentali hanno messo in luce che nel meccanismo patogenetico del danno al nervo ottico nel glaucoma, l'equilibrio tra la pressione intraoculare e la pressione sistemica rappresenta un parametro importante. In una popolazione non glaucomatosa, selezionata con pressione intraoculare normale e valori sia normali che alti della ...
