Objective: To explore the effects of ketamine inhalation before one-lung ventilation (OLV) in patients undergoing transthoracic esophagectomy for esophageal cancer.
Methods: Upon the approval of hospital ethic committee, 90 American Society of Anesthesiologists grade I-II patients scheduled for elective trans-left-thoracic esophagectomy for esophageal cancer were randomly and single-blindly divided into 3 groups. After intravenous anesthesia with double-lumen endobronchial intubation, the patients in each group received different therapies before OLV, i.e. inhaling ketamine 1 mg/kg in Group Ki, intravenous infusion of ketamine 1 mg/kg in Group Kv and inhaling normal saline 10 ml in Group C. Arterial blood gas analysis was performed. And (oxygen saturation) SpO2, (partial pressure of end-tidal carbon dioxide) PETCO2, (airway pressure) Paw and hemodynamic indicators were recorded at these points:before OLV (T1), OLV for 30 min (T2), OLV for 1 h (T3), OLV for 2 h (T4), OLV ended 5 min (T5) and end of surgery (T6). Central venous blood was sampled at T1, T2 and 2 h after surgery (T7) for the determination of interleukin-6 (IL-6), interleukin-8 (IL-8) and soluble intercellular adhesion molecule-1 (sICAM-1) concentrations by enzyme-linked immunosorbent assay (ELISA).
Results: Serum levels of IL-6, IL-8 and sICAM-1 in all groups increased significantly than those at previous timepoints. Serum levels of IL-6, IL-8 and sICAM-1 in Groups Ki and Kv were significantly lower than those in Group C at T7. PaO2 in Groups Ki and Kv was significantly higher than that in Group C at T4. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) in Group Kv were significantly higher than that in Groups Ki and C at T2-T4; HR in Group Kv was significantly higher than that in Group C at T2-T3. Paw in Group Kv was significantly higher than that in Group C at T2-T6.
Conclusion: Inhalation and intravenous infusion of ketamine before OLV are equally effective in lowering the serum levels of IL-6, IL-8 and sICAM-1. And ultrasonic atomizing inhalation of ketamine can avoid adverse effects on airway pressure and circulatory system caused by an intravenous infusion of ketamine.

Resting beat-to-beat blood pressure variability in humans: role of alpha-1 adrenergic receptors.
Clin Auton Res

Purpose: Resting beat-to-beat blood pressure variability is a strong predictor of cardiovascular events and mortality. However, its underlying mechanisms remain incompletely understood. Given that the sympathetic nervous system plays a pivotal role in cardiovascular regulation, we hypothesized that alpha-1 adrenergic receptors (the main sympathetic receptor controlling peripheral vasoconstriction) may contribute to resting beat-to-beat blood pressure variability.

Introduction: Angiotensin II may reduce muscle ischemia during intermittent hemodialysis and thereby decrease the incidence and/or intensity of intradialytic muscle cramps. We aimed to test whether angiotensin II infusion during intermittent hemodialysis is safe, feasible, and effective in the attenuation of muscle cramps.
Methods: We performed a pilot, single-blinded, randomized crossover trial of patients receiving intermittent hemodialysis who frequently experience intradialytic muscle cramps.
Ketamine Infusion for Complex Regional Pain Syndrome Treatment: A Narrative Review.
Curr Pain Headache Rep

Department of Anesthesiology, Louisiana State University Health Sciences Center at Shreveport, Shreveport, LA, 71103, USA.
Purpose Of Review: Complex Regional Pain Syndrome (CRPS) is a neuropathic pain disorder characterized by pain disproportionate to the inciting event that is constant for an extended duration. Numerous treatment options for this condition have been explored with unsatisfactory results in many cases. Ketamine, an N-methyl-D-aspartate (NMDA) receptor antagonist typically used as an anesthetic and analgesic, presents a promising potential treatment for CRPS in patients who fail to respond to traditional therapies.

Baicalein, one of the major active flavonoids found in Scutellaria baicalensis, has been revealed to exhibit potent anti-inflammatory properties in allergic airway inflammation. This study aimed to explore the role of baicalein and its relevant mechanism in the treatment of allergic rhinitis (AR). The bioinformatics tools were used to predict the targets of baicalein and AR-related genes.
