ANESTHESIA FOR UROLOGICAL AND GYNECOLOGICAL OPERATIONS [PDF]
Саратовский научно-медицинский журнал, 2008 The studies of free radical blood activity in surgical patients of urological and gynecological profile, operated under regional anesthesia (RA) or total intravenous anesthesia (TIVA) have demonstrated that biochemical blood parameters, characteristics ...

Frontiers in Surgery, 2022 ObjectivePostoperative delirium (POD) starts in the recovery room and occurs up to 5 days after surgery. However, the POD guidelines issued by the European Society of Anesthesiology (ESA) suggest that the effect of regional anesthesia on POD is ...

Automated Multi-Drugs Administration During Total Intravenous Anesthesia Using Multi-Model Predictive Control [PDF]
arXiv, 2023 In this paper, a multi-model predictive control approach is used to automate the co-administration of propofol and remifentanil from bispectral index measurement during general anesthesia. To handle the parameter uncertainties in the non-linear output function, multiple Extended Kalman Filters are used to estimate the state of the system in parallel ...

Indian Journal of Pain, 2014 Introduction: IVRA is safe, technically simple, and cost effective technique compared to general anaesthesia with success rates of 94 to 98% for upper and lower limb surgeries. It also provides bloodless field during surgery.

Journal of Anaesthesiology Clinical Pharmacology, 2012 Introduction: Ketamine and dexmedetomidine decrease anesthetic requirement and provide analgesia to patients. We designed this study to compare the effect of dexmedetomidine and ketamine when added to lignocaine in intravenous regional anesthesia (IVRA).

Nerve Block Target Localization and Needle Guidance for Autonomous Robotic Ultrasound Guided Regional Anesthesia [PDF]
arXiv, 2023 Visual servoing for the development of autonomous robotic systems capable of administering UltraSound (US) guided regional anesthesia requires real-time segmentation of nerves, needle tip localization and needle trajectory extrapolation. First, we recruited 227 patients to build a large dataset of 41,000 anesthesiologist annotated images from US videos

Macaque's Cortical Functional Connectivity Dynamics at the Onset of Propofol-Induced Anesthesia [PDF]
arXiv, 2021 Propofol, when administered for general anesthesia, induces oscillatory dynamic brain states that are thought to underlie the drug's pharmacological effects. Despite the elucidation of propofol's mechanisms of action at the molecular level, its effects on neural circuits and overall cortical functioning, which eventually lead to unconsciousness, are ...

Impact of hyperoxia and phenylephrine on cerebral oxygenation: An experimental clinical study
Acta Anaesthesiologica Scandinavica, Volume 67, Issue 1, Page 57-65, January 2023., 2023 Abstract Background Oxygen supply to the brain is of special importance during intracranial surgery because it may be compromised by intracranial pathology. A high arterial blood pressure (mean arterial pressure above 80 mmHg) and a high arterial oxygen tension (PaO2 above 12 kPa) is therefore often targeted in these patients, when for example ...

Reduced neural activity during volatile anesthesia compared to TIVA: evidence from a novel EEG signal processing analysis [PDF]
arXiv, 2020 Post-operative cognitive decline is a well-known phenomenon and of crucial importance especially in the elderly. General anesthesia can be accomplished by inhalation-based (volatile) or total intravenous anesthesia (TIVA). While their effects on post-operative symptoms have been investigated, little is known about their influence on brain ...
