Update on the Mechanism and Treatment of Sevoflurane-Induced Postoperative Cognitive Dysfunction.

Front Aging Neurosci 2021 8;13:702231. Epub 2021 Jul 8.

Department of Anesthesiology, The Second Affiliated Hospital, Fujian Medical University, Quanzhou, China.

Sevoflurane is one of the most widely used anesthetics for the induction and maintenance of general anesthesia in surgical patients. Sevoflurane treatment may increase the incidence of postoperative cognitive dysfunction (POCD), and patients with POCD exhibit lower cognitive abilities than before the operation. POCD affects the lives of patients and places an additional burden on patients and their families. Read More

Activation of Ca/Calmodulin-Dependent Protein Kinase II (CaMKII) with Lidocaine Provokes Pyroptosis of Glioblastoma Cells.

Bull Exp Biol Med 2021 Jul 24. Epub 2021 Jul 24.

Department of Anesthesiology, The Second Affiliated Hospital of Nanchang University, City, Nanchang, China.

The study examines the problem whether pyroptosis of U87-MG glioblastoma cells can result from activation of Ca/calmodulin-dependent protein kinase II (CaMKII) by a local anesthetic. Glioblastoma cells exposed to various concentrations of typical local anesthetic lidocaine demonstrated augmented cytosolic flux of Ca, while suppression of CaMKII expression with the corresponding siRNA significantly inhibited this effect in cells treated with 2 mM lidocaine. Lidocaine up-regulated the expression of mRNA caspase-3 and gasdermin GSDME proteins, whereas silencing of CaMKII gene with siRNA significantly moderated this effect. Read More

Department of Anaesthesiology, Virgen de la Victoria University Hospital, 29010 Malaga, Spain.

Breast cancer is the leading cause of mortality in women. It is a heterogeneous disease with a high degree of inter-subject variability even in patients with the same type of tumor, with individualized medicine having acquired significant relevance in this field. The clinical and morphological heterogeneity of the different types of breast tumors has led to a diversity of staging and classification systems. Read More

Impact of anesthesia on static and dynamic functional connectivity in mice.

Neuroimage 2021 Jul 20;241:118413. Epub 2021 Jul 20.

Jikei University School of Medicine, 3-25-8 Nishishinbashi, Minato City, Tokyo 105-8461, Japan; Riken, 2-1 Hirosawa, Wako, Saitama 351-0198, Japan.

A few studies have compared the static functional connectivity between awake and lightly anesthetized states in rodents by resting-state fMRI. However, impact of light anesthesia on static and dynamic fluctuations in functional connectivity has not been fully understood. Here, we developed a resting-state fMRI protocol to perform awake and anesthetized functional MRI in the same mice. Read More

Brain Behav 2021 Jul 21:e02165. Epub 2021 Jul 21.

Department of Anesthesiology, Third Xiangya Hospital of Central South University, Changsha, China.

N-methyl-D-aspartate (NMDA) receptors mediate excitatory neurotransmission in the nervous system and are preferentially inhibited by general anesthetics such as sevoflurane. Spontaneous movement is a common complication during sevoflurane anesthesia induction and seriously affects operations. In this study, we investigated the relationship between NMDA polymorphisms and spontaneous movement during sevoflurane induction. Read More

Internal Medicine, Hurley Medical Center, Flint, Michigan, USA

A 32-year-old woman who misused multiple substances, including nitrous oxide (NO), sought medical advice after she subacutely developed bilateral lower extremity weakness without a sensory level but with ataxia-her significant other developed similar symptoms with vitamin B deficiency due to NO intake. Laboratory results revealed macrocytic anaemia despite normal B and folate levels, with serum markers pointing towards functional cobalamin deficiency. Spinal MRIs and cerebrospinal fluid analysis were unremarkable. Read More

Transversus Abdominis Plane Block Versus Intraperitoneal Local Anesthetics in Bariatric Surgery: A Systematic Review and Network Meta-analysis.

Obes Surg 2021 Jul 19. Epub 2021 Jul 19.

Department of Anesthesiology, Faculty of Medicine, University of Malaya, 50603, Kuala Lumpur, Malaysia.

Background: Transversus abdominis plane (TAP) block and intraperitoneal local anesthetics (IPLA) are widely investigated techniques that potentially improve analgesia after bariatric surgery.

Front Surg 2021 2;8:692734. Epub 2021 Jul 2.

Department of Anesthesiology and Perioperative Medicine, Henan University People's Hospital, Henan Provincial People's Hospital, Zhengzhou, China.

Inflammatory cytokines are increased during one-lung ventilation in patients undergoing lung resection, and this increase can be fatal. Propofol and sevoflurane are the main anesthetics used for these patients. Unfortunately, there is no consensus on the best choice of an anesthetic agent concerning an inflammatory response in patients undergoing lung resection. Read More

Effect of Intravenous Dexmedetomidine on Spinal Anesthesia.

Cureus 2021 Jun 17;13(6):e15708. Epub 2021 Jun 17.

Anaesthesiology, ACS Medical College Hospital, Chennai, IND.

Background Subarachnoid block (SAB) with hyperbaric bupivacaine is routinely administered for abdominal and lower limb surgeries. Various agents have been used intrathecally as adjuvants to local anesthetic to increase efficacy and prolong the duration of SAB, among which opioids and α2 agonists are most commonly used. Intravenously administered dexmedetomidine has also been shown to prolong the duration of sensory and motor blockade obtained with subarachnoid block. Read More

Volatile Versus Intravenous Anesthetics in Cardiac Anesthesia: a Narrative Review.

Curr Anesthesiol Rep 2021 Jul 10:1-9. Epub 2021 Jul 10.

Department of Anesthesiology and Intensive Care Medicine, University Hospital and Medical Faculty, Cologne University, Albertus-Magnus-Platz, 50923 Cologne, Germany.

Purpose Of The Review: The present review addresses clinicians and gives an overview about the experimental rationale for pharmacological conditioning associated with volatile anesthetics, opioids, and propofol; the current clinical data; and the technical considerations regarding the clinical routine in cardiac anesthesia.

Recent Findings: Volatile anesthetics have been standard of care for general anesthesia for cardiac surgery, especially while using cardiopulmonary bypass. The 2019 published MYRIAD trial was not able to show a difference in mortality or cardiac biomarkers for volatile anesthetics compared to total intravenous anesthesia (TIVA), raising the question of equivalence with respect to patient outcome.
