the aim of this study is to find causes of cardiac disrhytmias during ophthalmic surgeries in patients under general anesthesia with no history of heart disease in iran’s educational hospitals. this was a univarient study. a sample of 250 patients selected randomly. data were gathered by four resources: interview, patient’s documents, kind of treatment selected by anesthesiologist and monitorin...

background: the aim of this study was to evaluate the effect of two injections doses of magnesium sulfate for controlling and reducing hemodynamic changes caused by laryngoscopy and endotracheal intubation in pregnant women who were candidates for caesarean section with general anesthesia. methods: in this controlled randomized double-blind clinical trial, 165 pregnant women who were candidates...

to study the role of preoperative intravenous magnesium sulphate in decreasing post-cesarean pain and opioid requirement during first 24hrs.in a double blind randomized clinical trial, prior to induction of general anesthesia, fifty elective cesarean candidates were randomly assigned to one of the two groups of placebo or magnesium sulfate. after surgery visual analogue scale (vas) and infused ...

acute paraplegia is a rare but catastrophic complication of surgeries performed on aorta and corrective operations of vertebral column. trauma to spinal cord after spinal anesthesia and ischemia of spinal cord also may lead to acute paraplegia. acute paraplegia as a complication of general anesthesia in surgeries performed on sites other than aorta and vertebral column is very rare. here we pre...

INTRODUCTION Emergence agitation after intracranial surgery is an important clinical issue during anaesthesia recovery. The aim of this multicentre cohort study is to investigate the incidence of emergence agitation, identify the risk factors and determine clinical outcomes in adult patients after intracranial surgery under general anaesthesia. Additionally, we will deliberately clarify the rel...

Background Inhaled volatile anaesthetics remain the most widely used drugs for maintenance of general anaesthesia because of their ease of administration and predictable intraoperative and recovery characteristics. The result has been an increasing reliance on fluorinated anesthetics. The most recently introduced anesthetics, desflurane and sevoflurane, are ethers halogenated solely with fluori...

Modified electroconvulsive therapy (ECT) is most often a day care procedure and requires an induction agent with a rapid onset and emergence. At the same time it should not increase the seizure threshold, or decrease the duration of seizures because the clinical outcome of ECT depends on the duration of seizures. Methohexital seems to be the gold standard [1] for induction of general anaesthesi...

BACKGROUND Xenon has minimal haemodynamic side effects when compared to volatile or intravenous anaesthetics. Moreover, in in vitro and in animal experiments, xenon has been demonstrated to convey cardio- and neuroprotective effects. Neuroprotection could be advantageous in paediatric anaesthesia as there is growing concern, based on both laboratory studies and retrospective human clinical stud...

Opioid dependence is a major health problem and a cause of increasing concern to physicians and other health professionals worldwide. A crucial first step in intervention is detoxification. Recent trends in medical practice have seen the emergence of newer techniques that claim to accelerate the detoxification procedure and ensure prevention of relapse by rapid induction onto maintenance treatm...

General anesthetics inhibit neurotransmitter release from both neurons and secretory cells. If inhibition of neurotransmitter release is part of an anesthetic mechanism of action, then drugs that facilitate neurotransmitter release may aid in reversing general anesthesia. Drugs that elevate intracellular cAMP levels are known to facilitate neurotransmitter release. Three cAMP elevating drugs (f...
