Increasing Robustness of the Anesthesia Process from Difference Patient's Delay Using a State-Space Model Predictive Controller [PDF]
Procedia Engineering 15 (2011) 928-932, 2013 The process of anesthesia is nonlinear with time delay and also there are some constraints which have to be considered in calculating administrative drug dosage. We present an Extended Kalman Filter (EKF) observer to estimate drug concentration in the patient's body and use this estimation in a state-space based Model of Predictive Controller (MPC) for

Edge AI-Based Vein Detector for Efficient Venipuncture in the Antecubital Fossa [PDF]
, 2023 Assessing the condition and visibility of veins is a crucial step before obtaining intravenous access in the antecubital fossa, which is a common procedure to draw blood or administer intravenous therapies (IV therapies). Even though medical practitioners are highly skilled at intravenous cannulation, they usually struggle to perform the procedure in ...

Laparoscopic appendectomy under spinal anesthesia with dexmedetomidine infusion [PDF]
Korean Journal of Anesthesiology, 2014 BackgroundLaparoscopic appendectomy (LA) is rarely performed under regional anesthesia because of pneumoperitoneum-related problems. We expected that dexmedetomidine would compensate for the problems arising from spinal anesthesia alone.

Membrane Nanodomains Homeostasis During Propofol Anesthesia as Function of Dosage and Temperature [PDF]
, 2020 Some anesthetics bind and potentiate gamma-aminobutyric-acid-type receptors, but no universal mechanism for general anesthesia is known. Furthermore, often encountered complications such as anesthesia induced amnesia are not understood. General anesthetics are hydrophobic molecules easily dissolving into lipid bilayers.
