PURPOSE OF REVIEW: The purpose of this review is to take a look on some practical aspects of anesthetic care in the endoscopy suite, concerning the general approach, safety, and monitoring issues. RECENT FINDINGS: Concerning propofol popularity for sedation during endoscopic procedures new studies create doubt in the safety of higher doses of propofol used for sedation. Careful titration of propofol, addition of synergistic supplements like ketamine and dexmedetomidine, and monitoring of anesthetic depth may limit the dose of propofol given to the patients...

BACKGROUND: The optimal approach to sedation for pleuroscopy remains undefined. Propofol is the favored sedative-hypnotic for many proceduralists but has a narrow therapeutic window and the risk for oversedation is high. Propofol-based sedation administered by anesthesiologists and the routine use of end-tidal capnography and bispectral index (BIS) monitoring may attenuate risks of complications. OBJECTIVES: The purpose of our study was to evaluate the safety and efficacy of monitored anesthesia care for pleuroscopy...

The awake brain surgery is an innovative approach in the treatment of tumors in the functional areas of the brain. There are various anesthetic techniques for awake craniotomy (AC), including asleep-awake-asleep technique, monitored anesthesia care, and the recent introduced awake-awake-awake method. We describe our first experience with anesthetic management for awake craniotomy, which was a combination of these techniques with scalp nerve block, and propofol/rémifentanil target controlled infusion. A 28-year-oldmale underwent an awake craniotomy for brain glioma resection...

BACKGROUND: During facemask ventilation, gastric insufflation is defined as appearance of a comet-tail or an acoustic shadow on ultrasonography. Ultrasonographic measurement of antral cross-section area (CSA) may reflect an insufflated antrum and provide interesting semi-quantitative data in regard to the gastric insufflation. This study aimed to determine the appropriate level of inspiratory pressure sufficient to provide adequate pulmonary ventilation with a lower occurrence of gastric insufflation during facemask pressure-controlled ventilation using real-time ultrasonography in paralyzed children...

INTRODUCTION: Assessment of the depth of anaesthesia is fundamental to the anaesthetic practice. Entropy measurement is an objective monitoring and is of two types- Response Entropy (RE) and State Entropy (SE) indicating analgesic and hypnotic levels during general anaesthesia. AIM: The aim of our study was to assess the depth of anaesthesia for LMA placement using entropy as a tool. The assessment of entropy as an indicator of depth of anaesthesia in the form of haemodynamic variations and success rate of LMA placement...

Drug-induced sleep endoscopy (DISE) is used to identify areas of upper airway obstruction, which occurs when patients with obstructive sleep apnea (OSA) snore. DISE enables effective diagnosis and appropriate treatment of the obstruction site. Among surgical treatment methods for OSA, maxillomandibular advancement surgery (MMA) is performed to move a jaw forward; the surgery has a high success rate for OSA treatment. In DISE, anesthetics such as propofol and midazolam must be administered to induce snoring while the patient is deeply sedated for an accurate diagnosis to be made...

BACKGROUND: The majority of critically ill patients experience distress during their stay in the Intensive Care Unit (ICU), resulting from systemic illness, multiple interventions and environmental factors. Providing humane care should address concomitant treatment of pain, agitation and delirium. The use of sedation and approaches to ICU delirium should be monitored according to structured guidelines. However, it is unknown to what extent these concepts are followed in Eastern European countries like Poland...

Transcranial motor evoked potentials (TcMEPs) monitor the integrity of the spinal cord during spine surgery. Propofol-based anesthesia is favored in order to enhance TcMEP quality. During intraoperative hemorrhage, TcMEP amplitudes may be reduced. The serum concentration of propofol may increase during hemorrhage. No study has determined whether changes in TcMEPs due to hemorrhage are related to changes in propofol blood levels. We monitored TcMEPs, mean arterial pressure (MAP), and cardiac output (CO) and hemoglobin in pigs (n = 6) undergoing controlled progressive hemorrhage during a standardized anesthetic with infusions of propofol, ketamine, and fentanyl...

BACKGROUND: Congenital insensitivity to pain with anhidrosis is a rare autosomal recessive disorder characterized by hyperpyrexia, anhidrosis, pain insensitivity, self-inflicted injuries, and intellectual disability. The anesthetic management of these patients is challenging owing to the high risk of perioperative complications resulting from their autonomic dysfunction, such as hyperthermia, hypotension, and bradycardia, which result from autonomic nervous system dysfunction. CASE PRESENTATION: Two 3-year-old Han Chinese identical male twins (weighing 13...

Provision of adequate sedation is a fundamental part of caring for critically ill patients. Propofol, dexmedetomidine, and benzodiazepines are the most commonly administered sedative medications for adult patients in the intensive care unit (ICU). These agents are limited by adverse effects, need for a monitored environment for safe administration, and lack of universal effectiveness. Recently, there has been increased interest in repurposing older pharmacologic agents for patient comfort in the intensive care unit...

We hypothesize that capnography could detect hypoventilation during induction of bronchoscopic sedation and starting bronchoscopy following hypoventilation, may decrease hypoxemia. Patients were randomized to: starting bronchoscopy when hypoventilation (hypopnea, two successive breaths of at least 50% reduction of the peak wave compared to baseline or apnea, no wave for 10 seconds) (Study group, n = 55), or when the Observer Assessment of Alertness and Sedation scale (OAAS) was less than 4 (Control group, n = 59)...

OBJECTIVE: ET-26 HCl is a promising sedative-hypnotic anesthetic with virtually no effect on adrenocortical steroid synthesis. However, whether or not ET-26 HCl also has a sufficiently wide safety margin and hemodynamic stability similar to that of etomidate and related compounds remains unknown. In this study, the effects of ET-26 HCl, etomidate and propofol on therapeutic index, heart rate (HR), mean arterial pressure (MAP), maximal rate for left ventricular pressure rise (Dmax/t), and maximal rate for left ventricular pressure decline (Dmin/t) were investigated in healthy rats and a rat model of uncontrolled hemorrhagic shock (UHS)...
