Perfusion Index and Pleth Variability Index in the First Hour of Life According to Mode of Delivery

, 2018
Perfusion index (PI) is a relative assessment of the pulse strength at the monitoring site. The plethysmographic variability index (PVI, pleth variability index) is a noninvasive and continuous measure of the dynamic change in PI that occurs during ...

Localized Temperature Monitoring in Mouse Brain during Light Delivery via a Non‐Planar Tapered Fiber‐Integrated µRTD Sensor

Advanced Materials, EarlyView.
We report a multifunctional tapered optical fiber integrating a conformal micro‐resistance temperature detector (µRTD) for local, real‐time thermometry during optical stimulation. The platform combines light‐delivery and temperature sensing within a minimally invasive footprint, enabling detection of sub‐degree cortical heating under representative ...

Evaluation of perfusion index as a predictor of successful caudal block in pediatric patients: A prospective randomized study

Journal of Anaesthesiology Clinical Pharmacology
Background and Aims: Caudal block is among the most widely administered regional anesthesia in pediatric patients. The clinical signs and objective assessments are not fast and reliable enough to provide a good feedback.

Correlation between peripheral perfusion index measured by pulse oximeter and blood pressure in neonates more than 35 weeks of gestation. [PDF]

, 2014
Peripheral haemodynamics determines oxygen and nutrient delivery to the tissues of the newborn infant. This deals with the microcirculation at the level of tissues, which is vital for adequate tissue perfusion and thus oxygenation.

Thermally Modulated Metasurface Sensor for Dynamic and Time‐Resolved Isolation of Extracellular Vesicles

Advanced Materials, EarlyView.
A thermally adaptive plasmonic metasurface, functionalized with poly(N‐isopropylacrylamide) (PNIPAM) and anti‐CD63 antibodies, enables precise, on‐demand capture and release of extracellular vesicles (EVs). Delivering high recovery, improved purity, and intact vesicle structure, the platform offers a versatile, label‐free solution for real‐time EV ...
