Some published criteria for intraoperative monitoring of PTH serum concentrations may cause misleading results, since the timing of samples measured between the pre-incision and pre-excision phase of surgery is often unrecorded. In our opinion this information is critical, as the time of an intermediate sample during surgical manipulation may represent the "true" beginning of the PTH decay. We ...

One of the greatest issues facing the cataract surgeon today is accurate prediction of post-operative refractive error. With use of intraoperative autorefractometry (IOAR), such errors can be detected and post-operative refractive errors avoided. An 83-year-old woman was admitted for right eye phacoemulsification, with aimed at -1.78D with Sanders/Retzlaff/Kraff/T (SRK/T) formula implantation u...

BACKGROUND AND PURPOSE Length of survival of patients with low-grade glioma correlates with the extent of tumor resection. These tumors, however, are difficult to distinguish intraoperatively from normal brain tissue, often leading to incomplete resection. Our goal was to evaluate the effectiveness of intraoperative MR guidance in achieving gross-total resection. METHODS We studied 12 patient...

PURPOSE This study used intraoperative monitoring of the access flow to evaluate the results of flow reduction in the management of high-flow arteriovenous access-related symptoms of distal ischemia and cardiac insufficiency. METHODS A retrospective study was conducted of 95 patients (78 with ischemia, 17 with cardiac failure) who underwent flow reduction between 1999 and 2005. A preoperative...

Advances in health information technology provide significant opportunities for improvements in surgical patient safety. The adoption and use of electronic health records can enhance communication along the surgical spectrum of care. Bar coding and radiofrequency identification technology are strategies to prevent retained surgical sponges and for tracking the operating room supply chain. Compu...

FOR the past 15 yr, there has been intense interest in the anesthesia community in the detection of intraand postoperative myocardial ischemia as a means of optimizing patient care because of the accumulated evidence suggesting a strong association with perioperative cardiac morbidity and long-term outcome. ',*It is important to understand the limitations of the methods of detecting myocardial ...

Different techniques have been described to prevent return flow of the blood into an intravenous line when both the intravenous infusion and blood pressure cuff have to be placed in the same arm especially during orthopedic surgeries of the upper limbs and with patients in lateral position. Some of these techniques involve placement of the part of the tubing under the blood pressure cuff, which...

BACKGROUND Endotracheal Tube Cuff Pressure (ETCP) should be kept in the range of 20 - 30 cm H2O. Earlier studies suggested that ETCP assessment by palpation of pilot balloon results in overinflation or underinflation and subsequent complications such as tracheal wall damage and aspiration. OBJECTIVES The current study aimed to evaluate the effect of an in vitro educational program on the abil...

~urol Neurosurg 1ge: clinical and complications, but the monitoring methods must be simple to perform, sensitive, and reliable. Median nerve somatosensory evoked potential (SEP) monitoring fulfills these criteria. Between 1985 nd 1990, we performed 994 h S. Successful operations of the carotid artery with SEP monitoring. In 92% of the cases, we were able t obtain viable SEP tracings. 3.. Case r...

BACKGROUND Intraoperative monitoring during carotid endarterectomy is crucial for cerebral protection. We investigated the results of carotid endarterectomy under dual monitoring with stump pressure and electroencephalography. METHODS We retrospectively reviewed the medical records of 50 patients who underwent carotid endarterectomy between March 2010 and February 2016. We inserted a temporar...
