Non-restraining EEG radiotelemetry is a valuable methodological approach to record in vivo long-term electroencephalograms from freely moving rodents. This detailed protocol describes stereotaxic epidural and deep intracerebral electrode placement in different brain regions in order to obtain reliable recordings of CNS rhythmicity and CNS related behavioral stages.

A novel technique to record the pressures within the skull is described. The minimally invasive method uses a fibre-optic pressure sensing system to accurately measure intracranial pressure (ICP) in anaesthetized rats without causing significant brain trauma. The technique may be used in a wide range of experimental models.

Local Anesthetics: Clinical Application as Epidural Anesthesia

Epidural anesthetics are administered in the fat-filled epidural space, the outermost part of the spinal canal. This technique is commonly employed for pain management and anesthesia during lower abdomen and pelvis surgeries or labor and delivery. Since epidural anesthetics can be infused through an epidural catheter, all types of drugs, including short-acting ones, can be administered. Chloroprocaine and lidocaine are examples of short and long-duration anesthetics, respectively. Bupivacaine...

Embryo Transfer Into Rabbit: A Procedure for Laparoscopy-Guided Transfer of Embryos Into Oviduct of Ovulating Recipient Female Rabbit Model
0 Views •
2025
This video describes the technique of transferring embryos into the oviduct of a recipient female rabbit via Laparoscopy. It allows embryo remodeling in rabbits during its migration through the oviduct, eventually helping in successful implantation. This technique can also be used for stored embryos with good efficiency.
FAQs
A temporal bone fracture can tear the middle meningeal artery, allowing blood to accumulate and exert increasing pressure on adjacent brain tissue. The danger is not simply the presence of blood, but the resulting mass effect: as pressure rises, normal brain structures may be displaced, potentially progressing to herniation. This mechanism explains the need for rapid recognition and intervention.
An initially brief period of preserved consciousness does not exclude serious injury. In epidural hematoma, bleeding may continue after trauma while neurological function appears temporarily stable. As the collection enlarges, compression can produce deterioration. Clinicians therefore treat apparent wellness as a potential warning phase rather than reassurance, reinforcing the value of repeated neurological assessment.
Noncontrast computed tomography provides the key imaging assessment described for this emergency. The hemorrhage typically appears as a lens-shaped collection, a pattern that helps identify its location and supports urgent management. CT findings must be interpreted alongside neurological assessment, because the clinical risk depends on whether the expanding collection is producing harmful compression.
Evaluation combines neurological assessment with noncontrast computed tomography. The examination identifies clinical change, while CT demonstrates the hemorrhage and its characteristic lens-shaped appearance. Using both sources of information supports timely triage, allowing clinicians to recognize a potentially expanding lesion and direct the patient toward urgent neurosurgical management.
Urgent neurosurgical evacuation addresses the threat created by increasing mass effect. Removing the accumulated blood can reduce compression and help prevent herniation, the dangerous displacement that makes rapid expansion potentially fatal. Treatment therefore centers on promptly controlling the mechanical pressure on the brain rather than waiting for further neurological deterioration.
Craniotomy is often used as the operative approach for evacuating an epidural hematoma. In the setting described, the procedure helps relieve the mass effect produced by the blood collection and supports prevention of herniation. Its clinical value lies in addressing the immediate compressive problem after assessment identifies a lesion requiring urgent surgical management.
