We report spontaneous hemodynamic activity termed "Spontaneous BOLD Waves" (SBWs) detected by BOLD fMRI in Sprague-Dawley rats under medetomidine anesthesia. These SBWs, which lasted several minutes, were observed in cortex, thalamus and hippocampus. The SBWs' correlates were undetectable in electrophysiological recordings, suggesting an exclusive gliovascular phenomenon dissociated from neuronal activity. SBWs were insensitive to the NMDA receptors antagonist MK-801 but were inhibited by the α1-adrenoceptor blocker prazosin...

Background: The elimination of anesthetic agents is a decisive factor in the emergence from general anesthesia. In this pilot study, we hypothesized that hypercapnia would decrease the emergence time from propofol anesthesia by increasing cardiac output and cerebral blood flow. Methods: A total of 32 patients were randomly divided into two groups based on the end-tidal carbon dioxide values: 30 mmHg (the hypocapnia group) and 50 mmHg (the hypercapnia group). Propofol and remifentanil were infused to maintain a bispectral index of 40-50...

INTRODUCTION: Veno-arterial extracorporeal life support (ECLS) is increasingly being used to treat rapidly progressing or severe cardiogenic shock. However, it has been repeatedly shown that increased afterload associated with ECLS significantly diminishes left ventricular (LV) performance. The objective of the present study was to compare LV function and coronary flow during standard continuous-flow ECLS support and electrocardiogram (ECG)-synchronized pulsatile ECLS flow in a porcine model of cardiogenic shock...

The recent adoption of an improved lymphatic access technique coupled with Dynamic Contrast-enhanced Magnetic Resonance Lymphangiography has introduced the ability to diagnose and treat severe lymphatic disorders unresponsive to other therapies. All pediatric patients presenting for lymphatic procedures require general anesthesia presenting challenges in managing highly morbid and comorbid conditions both from logistical as well as medical aspects. General anesthesia is used because of the procedural requirement for immobility to accurately place needles and catheters, treat pain secondary to contrast and glue injections, and to accommodate additional procedures...

Stenting at the flow-limiting segment can improve the ventilation-perfusion ratio in patients with central airway stenosis. However, there is no quantitative examination for assessing the perfusion status during interventional bronchoscopy. Intrabronchial capnography can estimate regional gas exchange by measuring carbon dioxide concentration. We herein report a case of bilateral bronchial stenosis where stenting was able to improve ventilation-perfusion ratio using intrabronchial capnography. A 44-year-old man was admitted to our institution with orthopnea...

BACKGROUND: Birth asphyxia is a leading cause of early neonatal death. In 2013, 32% of neonatal deaths in Zambia were attributable to birth asphyxia and trauma. Basic, timely interventions are key to improving outcomes. However, data from the World Health Organization suggest that resuscitation is often not initiated, or is conducted suboptimally. Currently, there are little data on the quality of newborn resuscitation in the context of a tertiary center in a lower-middle income country...

Ventilator-induced lung injury aggravates the existing lung injury. This study investigated the effect of desflurane on VILI in a rat model of acute respiratory distress syndrome. Forty-eight rats were randomized into a sham (S) group, control (C) group, lipopolysaccharide/ventilation (LV) group, lipopolysaccharide/ventilation/desflurane (LVD) group, or lipopolysaccharide/low ventilation with and without desflurane (LLV and LLVD) groups. Rats in the S group received anesthesia only. Rats in the LV and LVD groups received lipopolysaccharide and were ventilated with a high tidal volume...

Obesity affects respiratory and hemodynamic function in anesthetized patients. The aim of this study was to evaluate the influence of the body mass index (BMI) on pulmonary changes in a permanent 45° steep Trendelenburg position (STP) during robotic-assisted laparoscopic prostatectomy (RALP). 51 patients undergoing RALP under standardized anesthesia were included. Perioperative pulmonary function and oxygenation were measured in awake patients (T0 ), 20 min after the induction of anesthesia (T1 ), after insufflation of the abdomen in supine position (T2 ), after 30 min in STP (T3 ), when controlling Santorini's plexus in STP (T4 ), before awakening while supine (T5 ), and after 45 min in the recovery room (T6 )...

OBJECTIVE: Regarding the fact that rigid bronchoscopy is generally performed under general anesthesia and this patient subgroup is remarkably morbid, encountering procedure and/or anesthesia related complications are highly likely. Here, we aimed to assess factors influencing recovery and detect possible determinants of adverse event occurence during these operations performed in a tertiary referral centre. METHODS: 81 consecutive ASA I-IV patients were recruited for this investigation...

Airway management and ventilation during a tracheobronchial stenting procedure are challenging given that mandatory positive pressure ventilation cannot be fully achieved while using a rigid bronchoscope due to leakage from the scope tip. Biphasic cuirass ventilation is a negative pressure ventilation method using an external cuirass fitted to the anterior chest, which could assist in spontaneous breathing and ventilation support. We report 3 successful anesthesia cases in which we could maintain adequate ventilation and oxygenation, supported by biphasic cuirass ventilation, in patients undergoing tracheobronchial stent placement or removal procedures using rigid bronchoscopy...

Renal tubular acidosis (RTA) with hypokalemia may precipitate acute respiratory failure and potentially fatal arrhythmias like ventricular fibrillation. Though there are random reports of respiratory failure needing mechanical ventilation and sudden death in patients with RTA and hypokalemia, the anesthetic management of these patients has not been clearly elucidated. Acidosis and hypokalemia have significant interactions with both general and local anesthetics and alter their effect substantially. Proper preoperative planning and optimization are required for the safe conduct of anesthesia in this subset of patients...

Background and Aims: Opioids are associated with postoperative nausea, vomiting, drowsiness, and increased analgesic requirement. A nonopioid anesthesia technique may reduce morbidity, enable day care surgery, and possibly decrease tumor recurrence. We compared opioid-free, nerve block-based anesthesia with opioid-based general anesthesia for breast cancer surgery in a prospective cohort study. Material and Methods: Twenty four adult American Society of Anesthesiologists grade I-III patients posted for modified radical mastectomy (MRM) with axillary dissection were induced with propofol and maintained on isoflurane (0...

AIM: One-lung ventilation (OLV) is an anesthesia technique used to provide visualization in thoracoscopic lung surgeries and increase surgical site visibility during operation. In OLV, atelectasis occurs and blood from the lung participates in circulation without receiving oxygen. We designed a prospective study on patients we implemented surgery in order to research whether OLV leads to oxidative stress and DNA damage or not. METHODS: It was taken 5cc blood samples 4 times from these patients in the postoperative preparatory stage (T1), on the 60th minute after the start of OLV (T2), on the 60th minute after the termination of OLV (T3) and 24 hours after surgery (T4)...

In thoracic surgery, the introduction of video-assisted thoracoscopic techniques has allowed the development of fast-track protocols, with shorter hospital lengths of stay and improved outcomes. The perioperative management needs to be optimized accordingly, with the goal of reducing postoperative complications and speeding recovery times. Premedication performed in the operative room should be wisely administered because often linked to late discharge from the post-anesthesia care unit (PACU). Inhalatory anesthesia, when possible, should be preferred based on protective effects on postoperative lung inflammation...
