Peripheral nerve injuries are largely preventable injuries that can result from incorrect patient positioning during surgery. Patients who are diabetic, are extremely thin or obese, use tobacco, or undergo surgery lasting more than four hours are at increased risk for developing these injuries. When peripheral nerve injuries occur, patients may experience numbness, burning, or tingling and may ...

BACKGROUND We present a case of a patient with multinodular goiter disease who suffered asystole during head hyperextension for surgical positioning on the operational table. CASE PRESENTATION Manipulation of carotid sinus may trigger bradycardia or even asystole even in patients without prior history of carotid sinus hypersensitivity. The time proximity between patient positioning and asysto...

BACKGROUND We present a case report of a patient with recurrent thyroid carcinoma, previously treated with surgery and radiotherapy, who developed asystolic episodes on 2 occasions as the result of positioning of the neck in hyperextension for head and neck surgery. METHODS AND RESULTS In carotid sinus hypersensitivity (CSH), the carotid sinus reflex is greatly exaggerated, resulting in profo...

One of the most common positioning errors in panoramic radiography is the palatoglossal air space above the apices of the root of maxillary teeth. It causes a radiolucency obscuring the apices of maxillary teeth. In the case of this positioning error, the imaging should be repeated. This causes the patient to be exposed to radiation again. To avoid the repetition of exposing harmful X-rays to t...

Background/introduction Treatment duration as well as time spent on patient positioning imposes limitations on therapeutic use of MRguided High Intensity Focused Ultrasound (MR-HIFU). Reduction of overall treatment time is especially important in potential pediatric applications and in other cases where general anesthesia must be used, due to the risks associated with prolonged anesthesia. Typi...

The design and testing of a pneumatic optical positioning interface produced with the goal of improving fiber positioning in magnetic resonance (MR)-guided diffuse spectral imaging of breast cancer is presented. The system was created for vertical positioning of optical fibers inside the MR bore during a patient exam to target suspicious lesions with MR scans for reference and collect multiple ...

PURPOSE Internal limiting membrane (ILM) peeling in macular hole surgery may allow a shortened period of face down positioning. This study reports the results of macular hole surgery combined with shortened (3-day) face down positioning. METHODS The study was a retrospective review of data for 21 patients (21 eyes) treated for a macular hole by a single surgeon (G.K.S.). All patients underwen...

An appropriate positioning of a total knee replacement (TKR) is a prerequisite for a good functional outcome and a prolonged survival (1). Navigation systems may facilitate the proper positioning of the implants (2). Patient specific templates have been developed to achieve at least the same accuracy than conventional instruments at a lower cost (3). The learning curve of such systems has not y...

In this paper, combined GPS and GLONASS positioning systems are discussed and some solutions have been proposed to improve the accuracy of navigation. Global Satellite Navigation System (GNSS) is able to provide position, velocity and time with respect to coordinated universal time. GNSS positioning is based on received satellite signals, so its performance is highly dependent on the quality of...
