BACKGROUND Lumbar puncture is often used for the diagnosis and treatment of subarchnoid hemorrhage, infection of Cerebro-spinal Fluid (CSF), hydrocephalus in neurosurgery department patients. It is general that paradoxical herniation followed by lumbar puncture is quite rare in decompressive craniectomy cases; the related reports are very few. Moreover, most of the paradoxical herniation cases ...

BACKGROUND This study investigated whether a tensioning headband that applies up to 20 mmHg pressure over a forehead pulse oximetry sensor could improve arterial hemoglobin oxygen saturation reading accuracy in presence of venous pooling and pulsations at the forehead site. METHODS Healthy volunteers were studied breathing room air in supine and various levels of negative incline (Trendelenbu...

swelling or expressed a preference for this posture. I do, however, maintain the lower limbs in the horizontal position. A patient can just as readily faint in the horizontal as in the sitting position. Some time ago I had a young, healthy female patient who, while in the supine position, fainted following the insertion of the intravenous needle before any methohexitone had been injected. She b...

Purpose. To evaluate perioperative risk factors for corneal abrasion (CA) and to determine current care for perioperative CA in a tertiary care setting. Methods. Hospital-based, cross-sectional study. In Operating Room and Post-Anesthesia Care Units patients, a comparison of cases and controls was evaluated to elucidate risk factors, time to treatment, and most common treatments prescribed for ...

BACKGROUND Respiratory variations in the pulse oximeter plethysmographic waveform amplitude (deltaPOP) are sensitive to changes in preload and can predict fluid responsiveness in mechanically ventilated patients. However, they cannot be easily calculated from a bedside monitor. Pleth variability index (PVI, Masimo Corp., Irvine, CA) is a new algorithm that automatically calculates deltaPOP. The...
