Myasthenia gravis (MG) is an autoimmune disease characterized by the production of antibodies against the acetylcholine receptor, muscle-specific kinase (MuSK), or other proteins at the neuromuscular junction. MG with antibodies against MuSK (MuSK-MG) has been described recently. Here, we report the first case of anesthetic management of a patient with MuSK-MG undergoing an open cholecystectomy. In our case, propofol and remifentanil-based anesthesia were used for successful management without using muscle relaxants...

BACKGROUND: Several studies indicate that remifentanil exposure may engender opioid-induced hyperalgesia. Butorphanol and flurbiprofen axetil are proposed as adjunctive analgesics for postoperative pain control. This randomized double-blind controlled study was designed to investigate the antihyperalgesic effects of butorphanol combined with flurbiprofen axetil on opioid-induced hyperalgesia. METHODS: One hundred and twenty patients undergoing elective laparoscopic gynaecological surgery with sevoflurane anaesthesia were randomized to one of four groups, as follows: intraoperative sufentanil 0...

INTRODUCTION: Cardiopulmonary bypass (CPB) can cause stress response that increases levels of cytokine and catecholamine in plasma, resulting in hyperglycemia. In adults, it has been demonstrated that remifentanil infusion during CPB could prevent increases of cytokine, catecholamine, and blood glucose levels, but such effects of remifentanil in children have not been elucidated. AIM: In this study, we investigated the preventive effects of remifentanil on blood glucose and lactate levels during CPB in children...

A 24-year-old woman at 29 weeks' gestation, and with psychiatric symptoms, was admitted to hospital and diagnosed as having anti-N-methyl-D-aspartate receptor encephalitis. After 4 weeks of immunotherapy with little effect, an emergency cesarean section was performed at 33(+4) weeks gestation under general anesthesia. The parturient was intubated after rapid sequence induction with etomidate, remifentanil and succinylcholine. Anesthesia was maintained with sevoflurane and remifentanil. Except for low weight, the infant was normal at birth...

PURPOSE: Several factors affect the accuracy of non-invasive continuous hemoglobin concentration (SpHb) measurements. We had previously shown an increase in the perfusion index (PI) following induction of anesthesia which was associated with an increase in the difference between SpHb and total hemoglobin (tHb) (SpHb-tHb). We hypothesized that blunting the increase in PI by maintaining blood pressure during induction of anesthesia would improve the agreement between SpHb and tHb measurements...

Opioid painkillers are a promising treatment for chronic breathlessness, but are associated with potentially fatal side effects. In the treatment of breathlessness, their mechanisms of action are unclear. A better understanding might help to identify safer alternatives. Learned associations between previously neutral stimuli (e.g. stairs) and repeated breathlessness induce an anticipatory threat response that may worsen breathlessness, contributing to the downward spiral of decline seen in clinical populations...

Cysteine protease cathepsin S (CatS) expressed by spinal microglia has been shown to play a critical role in nerve injury and inflammation-induced chronic pain. However, whether microglial CatS contributes to remifentanil-induced acute hyperalgesia remains unstudied. In the present study, intravenous remifentanil infusion induced a significant increase in the expression of premature and mature form of CatS in the activated microglia in the spinal cord. Spinal delivery of irreversible CatS inhibitor LHVS reduced hyperalgesia, attenuated activation of spinal microglia and blocked phosphorylation of N-methyl-d-aspartate (NMDA) receptor NR1 subunit induced by remifentanil...

PURPOSE OF REVIEW: The present article summarizes anesthetic techniques used during functional endoscopic sinus surgery to decrease bleeding and aid in creating a clear surgical field. The applicable physiology behind these anesthetic techniques is reviewed with emphasis on the effect on bleeding and the surgical field. Deliberate hypotension, reverse Trendelenburg positioning, regional anesthesia, and cerebral monitoring are discussed. RECENT FINDINGS: There are mixed data as to whether traditional inhalation anesthesia or total intravenous anesthesia is superior with respect to better surgical fields and decreased blood loss...

BACKGROUND: The introduction of routine prenatal screening using ultrasound has led to a substantial increase in diagnoses of fetal disorders that are amenable to intrauterine treatment. While an ultrasound guided insertion of small bore cannulas can be performed under local anesthesia, insertion of a fetoscope usually requires anesthetic management for the mother and the fetus. Additionally, the fetus' intrauterine position may have to be manipulated in order to enable access. Such manoeuvres depend on relaxation of the mother's abdominal wall...
