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...

PURPOSE To illustrate the anesthetic management of a craniotomy for suprasellar meningioma in a 28-week pregnant woman and to review the considerations for fetal monitoring during surgery. CLINICAL FEATURES A 33-yr-old woman presented at 28 weeks of gestation with rapidly deteriorating vision in her right eye. Neuroradiological investigations revealed a large suprasellar meningioma extending ...

The use of personal protective equipment (PPEs) in the construction industry is necessary to guarantee the safety of the workers. However, this equipment is not usually worn properly. Nowadays, the only control performed over the use of PPEs consists of a visual inspection. This paper introduces a novel cyberphysical system (CPS) to check in real time how the PPEs are worn by the workers. In or...

In 1990, Clarke and Hall carried out a survey of anaesthetic mortality in small animal practice. Their findings suggested that approximately 1 in 679 healthy dogs and cats died as a result of anaesthesia, while the figure increased to 1 in 31 for sick patients. More recently, the preliminary results of a Confidential Enquiry into Perioperative Small Animal Fatalities (CEPSAF) indicated that the...

OBJECTIVE To review the experience at a single institution with motor evoked potential (MEP) monitoring during intracranial aneurysm surgery to determine the incidence of unacceptable movement. METHODS Neurophysiology event logs and anesthetic records from 220 craniotomies for aneurysm clipping were reviewed for unacceptable patient movement or reason for cessation of MEPs. Muscle relaxants w...

This article looks at the current techniques and equipment recommended for the management of the difficult intubation scenario in pediatric practice. We discuss the general considerations including preoperative preparation, the preferred anesthetic technique and the use of both rigid laryngoscopic and fiberoptic techniques for intubation. The unanticipated scenario is also discussed.

The optimum conditions for cardiothoracic surgery have traditionally been regarded as a “still and bloodless” surgical field. Cardiopulmonary bypass (CPB) provides this by incorporating a pump to substitute for the function of the heart and a gas exchange device, the “oxygenator,” to act as an artificial lung. CPB thus allows the patient’s heart and lungs to be temporarily devoid of circulation...

During the last three decades, there have been many new developments in condition monitoring (CM) of high voltage equipment in electrical power systems. Hundreds of new instruments are in use around the world. Enormous quantities of CM data are collected from on-line and off-line tests every day. Now it might be the right time to ask “Are we using CM instruments wisely?” In fact, one of the pro...
