BACKGROUND: It has been observed that patients with liver dysfunction need lower dose anesthetic compared patients with normal liver function. The minimum amount of volatile anesthetic to achieve an optimal depth of anesthesia for these patients is still unclear. In this study, Minimum alveolar concentration (MAC) of the sevoflurane was determined using an electric stimulation and the effect of severity of liver dysfunction on the MAC was observed in cirrhotic patients. METHODS: Thirty patients undergoing upper abdominal surgery were divided into the following groups: group N (normal liver function), group A (Child-Pugh grade A) and group B (Child-Pugh grade B-C)...

BACKGROUND: To date, general anesthesia has been suggested as the preferred approach for implantation of a subcutaneous implantable cardioverter-defibrillator (S-ICD). The purpose of this study was to assess the use of monitored anesthesia care (MAC) for S-ICD implantation. The goals were to assess adequate sedation and analgesia (efficacy endpoints) and major perioperative airway or hemodynamic compromise (safety endpoints). The authors hypothesized that MAC may provide adequate sedation and analgesia and no major perioperative airway or hemodynamic compromise during S-ICD implantation and multiple defibrillation threshold (DFT) testing...

BACKGROUND: Peripheral vasodilation is a well-recognized side effect of general anesthesia, and induces changes in the amplitude of the pulse plethysmograph (PPG) waveform. This can be continuously quantitaed using the Perfusion Index (PI), a ratio of the pulsatile to nonpulsatile signal amplitude in the PPG waveform. We hypothesized that the perfusion index would rise with the induction of anesthesia in children, and fall with emergence, and performed a prospective, observational study to test this...

Utilization of monitored anesthesia care (MAC) for gastrointestinal endoscopy has increased markedly over the past decade, leading to significant additional health care expenditures. However, the extent to which certain patient-, provider-, and facility-level factors lead to MAC utilization is unclear. A systematic review of 13 studies evaluating influential factors associated with MAC utilization for colonoscopy and/or esophagogastroduodenoscopy was conducted. Multiple studies revealed significant increases in MAC utilization since the early 2000s, with substantial regional variation...

BACKGROUND: Dexmedetomidine as a sole agent showed limited use for painful procedures due to its insufficient sedative/analgesic effect, pronounced hemodynamic instability and prolonged recovery. The aim of this study was to compare the effects of dexmedetomidine-ketamine (DK) versus dexmedetomidine-midazolam-fentanyl (DMF) combination on the quality of sedation/analgesia and recovery profiles for monitored anesthesia care (MAC). METHODS: Fifty six patients undergoing chemoport insertion were randomly assigned to group DK or DMF...

PURPOSE: Volatile anesthetics possess cardioprotective properties, but it is unknown if the cardioprotective effects extend equally to all members of the class. Although sevoflurane is a relatively newer anesthetic than isoflurane, its introduction into practice was not preceded by a head-to-head comparison with isoflurane in a trial focusing on clinically important outcomes. Our objective was to determine whether sevoflurane was non-inferior to isoflurane on a clinically important primary outcome in a heterogeneous group of adults undergoing cardiac surgery...

BACKGROUND: Postoperative airway compromise following cervical spine surgery is a potentially serious adverse event. Residual effects of anesthesia and perioperative opioids that can cause both sedation and respiratory depression further increase this risk. Ketamine is an N-methyl-d-aspartate (NMDA) receptor antagonist that provides potent analgesia without noticeable respiratory depression. We investigated whether intraoperative ketamine administration could decrease perioperative opioid requirements in trauma patients undergoing cervical spine surgery...

We experienced a case of successful nasotracheal intubation using the X-Blade of the McGrath MAC in a 28-year-old woman with a 2.5-cm mouth opening. She had no teeth on the right side, her neck movement was limited, her mandibular protrusion was grade C, and her Mallampati could not be evaluated. Her tongue was fixed to the left wall during a previous surgery. We evaluated the awake glottic view using the McGrath MAC X-Blade and topical oral anesthesia. We obtained a Cormack-Lehane grade II view and then decided to administer general anesthesia...

Minimum alveolar concentration (MAC) is a reliable measurement of the potency of inhaled anesthetic agents. The determination of MAC in different species has followed a fairly consistent methodology. In people, MAC is determined with the up-and-down method, whereas in animal the bracketing technique is commonly used. The objectives of this study were to determine the MAC value of isoflurane in dogs and cats using the up-and-down method and to determine the MAC value of isoflurane at extubation (MACex). General anesthesia was induced in 13 dogs and 5 cats with 5% isoflurane in oxygen...

INTRODUCTION: Sufficient ventilation and oxygenation through proper airway management is essential in patients undergoing cardio-pulmonary resuscitation (CPR). Although widely discussed, securing the airway using an endotracheal tube is considered the standard of care. Endotracheal intubation may be challenging and causes prolonged interruption of chest compressions. Videolaryngoscopes have been introduced to better visualize the vocal cords and accelerate intubation, which makes endotracheal intubation much safer and may contribute to intubation success...

We report the successful anesthetic management of video-assisted left upper lobectomy in a patient with ischemic heart disease using an intra-aortic balloon pump (IABP). An 81-year-old man with severe ischemic heart disease was scheduled for partial lobectomy for suspected lung cancer under general anesthesia. Although he had severe ischemic heart disease, coronary intervention such as percutaneous cardiac intervention or coronary artery bypass grafting was impossible due to severe coronary stenosis. IABP was instituted through the femoral artery before inducing anesthesia...

We report the anesthetic management of a pediatric case of blue rubber bleb nevi syndrome combined with small-intestinal intussusception. A 2-year-old girl was transferred to our hospital for small-intestinal intussusception. Emergent ablation of the upper gastrointestinal tract nevus under general anesthesia was planned. Given the presence of several nevi in the oral and pharyngeal space, we utilized the McGRATH MAC (McGRATH; Aircraft Medical Ltd, United Kingdom) laryngoscope for gentle and stress-free tracheal intubation...

A patient with Klippel-Feil syndrome had difficulties in inserting and placing an endotracheal tube under general anesthesia. Klippel-Feil syndrome, characterized by cervical vertebral fusion, scoliosis and endocardiosis, is a rare disease. Anesthesiologists should pay attention to management of anesthesia in airway troubles. A 53-year-old woman diagnosed with Klippel-Feil syndrome was scheduled for general anesthesia with intubation. We tried to insert an endotracheal tube using McGRATH MAC, but it was difficult to insert and place the tube...

Providing lidocaine, ketamine, and an opioid greatly decreases the minimum alveolar concentration (MAC) of volatile anesthetics in dogs. However, the efficacy of this combination shows marked interspecies variation, and opioids are likely to be less effective in pigs than in other species. The aim of the study was to determine the effects of constant-rate infusion of lidocaine and ketamine combined with either morphine or fentanyl on the MAC of sevoflurane in pigs. In a prospective, randomized, crossover design, 8 healthy crossbred pigs were premedicated with ketamine and midazolam, and anesthesia was induced and maintained with sevoflurane...

BACKGROUND: Hypertension often occurs after tracheal intubation using a Macintosh laryngoscope and may lead to rare but serious complications. The Macintosh laryngoscope may increase the incidence of hypertension because it requires forced alignment of the oral and pharyngeal axes in order to view the glottis. In contrast, the McGRATH MAC video laryngoscope does not require this manipulation. The objective of this study was to evaluate the incidence of hypertension after tracheal intubation using a McGRATH laryngoscope compared with a Macintosh laryngoscope...
