Kinetics of indocyanine green dye after intraocular surgeries using indocyanine green staining.
OBJECTIVE To determine the elimination kinetics of indocyanine green (ICG) after intraocular operations using ICG staining. METHODS Intraocular fluorescence of ICG was determined using the ICG angiographic mode of a scanning laser ophthalmoscope (in vivo) and fluorescence microscopy (in vitro) after circular curvilinear capsulorhexis with ICG staining during cataract surgery and internal limi...
متن کاملDoes precipitation reduce tissue staining by indocyanine green dye solutions?
PURPOSE Indocyanine green (ICG) dye precipitates when mixed with certain ophthalmic irrigation solutions. The purpose of this study is to investigate whether this precipitation reduces ICG staining of the anterior lens capsule. METHODS ICG was diluted with each of the following solutions: BSS Plus, physiological saline, or Opeguard Neo. The products were then examined for green precipitate by...
متن کاملMeasurements of Cerebral Arterial Oxygen Saturation
This pilot investigation was undertaken to assess the performance of a novel fiber-optic cerebral pulse oximetry system. A fiber-optic probe designed to pass through the lumen of a cranial bolt of the type used to make intracranial pressure measurements was used to obtain optical reflectance signals directly from the brain tissue. Preliminary results from seven patients measured in the operatin...
متن کاملCutaneous vasoconstriction affects near-infrared spectroscopy determined cerebral oxygen saturation during administration of norepinephrine.
BACKGROUND Perioperative optimization of spatially resolved near-infrared spectroscopy determined cerebral frontal lobe oxygenation (scO2) may reduce postoperative morbidity. Norepinephrine is routinely administered to maintain cerebral perfusion pressure and, thereby, cerebral blood flow, but norepinephrine reduces the scO2. We hypothesized that norepinephrine-induced reduction in scO2 is infl...
متن کاملThe effect of sevoflurane vs. TIVA on cerebral oxygen saturation during cardiopulmonary bypass--randomized trial.
BACKGROUND Neuropsychological and neurological deficits are still major causes of mortality and morbidity after cardiac surgery. These complications are thought to be caused by embolisms and cerebral hypoxia. Thus, continuous neuromonitoring is essential during cardiac surgery due to cerebral oxygen desaturation during different periods. Near-infrared spectrophotometry (NIRS), a non-invasive me...
