Cardiothoracic Surgery, Centro Hospitalar Universitário Lisboa Norte, Lisboa, Portugal.

Introduction/Study Goals: Thoracic sympathectomy is considered to be the most effective treatment for hyperhidrosis, a procedure traditionally performed under general anesthesia. Nowadays it's a minimally invasive procedure, which makes it possible to perform under sedation with local anesthesia. The goal in this study was to assess the efficacy and safety of this anesthetic technique in video-assisted thoracic sympathectomy. Read More

Neurologic Assessment of the Neurocritical Care Patient.

Front Neurol 2021 22;12:588989. Epub 2021 Mar 22.

Department of Neurosurgery, Joan C. Edwards School of Medicine, Marshall University, Huntington, WV, United States.

Sedation is a ubiquitous practice in ICUs and NCCUs. It has the benefit of reducing cerebral energy demands, but also precludes an accurate neurologic assessment. Because of this, sedation is intermittently stopped for the purposes of a neurologic assessment, which is termed a neurologic wake-up test (NWT). Read More

Propofol reduces the amplitude of transcranial electrical motor-evoked potential without affecting spinal motor neurons: a prospective, single-arm, interventional study.

J Anesth 2021 Apr 7. Epub 2021 Apr 7.

Department of Anesthesiology, Niigata University Medical and Dental Hospital, 1-754 Asahimachi-Dori, Chuo-ku, Niigata, 951-8520, Japan.

Purpose: Propofol inhibits the amplitudes of transcranial electrical motor-evoked potentials (TCE-MEP) in a dose-dependent manner. However, the mechanisms of this effect remain unknown. Hence, we investigated the spinal mechanisms of the inhibitory effect of propofol on TCE-MEP amplitudes by evaluating evoked electromyograms (H-reflex and F-wave) under general anesthesia. Read More

A Noninvasive Method for Quantifying Cerebral Metabolic Rate of Oxygen by Hybrid PET/MRI: Validation in a Porcine Model.

J Nucl Med 2021 Mar 19. Epub 2021 Mar 19.

Lawson Health Research Institute, Canada.

The gold standard for imaging the cerebral metabolic rate of oxygen (CMRO) is positron emission tomography (PET); however, it is an invasive and complex procedure that also requires correction for recirculating O-HO and the blood-borne activity. We propose a noninvasive reference-based hybrid PET/magnetic resonance imaging (MRI) method that uses functional MRI techniques to calibrate O-O-PET data. Here, PET/MR imaging of oxidative metabolism (PMROx) was validated in an animal model by comparison to PET-alone measurements. Read More

Smart Portable Pen for Continuous Monitoring of Anaesthetics in Human Serum with Machine Learning.

IEEE Trans Biomed Circuits Syst 2021 Mar 19;PP. Epub 2021 Mar 19.

Continuous monitoring of anaesthetics infusion is demanded by anaesthesiologists to help in defining personalized dose, hence reducing risks and side effects. We propose the first piece of technology tailored explicitly to close the loop between anaesthesiologist and patient with continuous drug monitoring. Direct detection of drugs is achieved with electrochemical techniques, and several options are present in literature to measure propofol (widely used anaesthetics). Read More

Int J Environ Res Public Health 2021 Feb 20;18(4). Epub 2021 Feb 20.

ENT Unit, "V.Fazzi" Hospital, 73100 ASL Lecce, Italy.

To analyze the middle latency auditory evoked potential index (MLAEPi), compared to the standard bispectral index (BIS), as a method for evaluating the sedation level in drug-induced sleep endoscopy (DISE). In this controlled clinical study on a sample of 99 obstructive sleep apnea (OSA) or snoring patients, we compared the MLAEPi with the BIS after propofol infusion during the standard DISE technique in order to define the MLAEPi values within the observational window of the procedure. The DISE procedure was divided into eight steps, and we collected both MLAEPi and BIS data values from the same patient in every step. Read More

Balanced Opioid-free Anesthesia with Dexmedetomidine versus Balanced Anesthesia with Remifentanil for Major or Intermediate Noncardiac Surgery.

Anesthesiology 2021 04;134(4):541-551

Background: It is speculated that opioid-free anesthesia may provide adequate pain control while reducing postoperative opioid consumption. However, there is currently no evidence to support the speculation. The authors hypothesized that opioid-free balanced anesthetic with dexmedetomidine reduces postoperative opioid-related adverse events compared with balanced anesthetic with remifentanil. Read More
