what the risks are --> intracranial pressure monitoring, icp monitoring, device, placed inside the head, which senses the pressure, sends its measurements to a recording device, three ways of monitoring intracranial pressure, intraventricular catheter, a catheter threaded into one, the lateral ventricles, the brain, a subarachnoid screw, bolt, a screw, bolt placed, the skull, in the space between the arachnoid, cerebral cortex, epidural sensor, a sensor placed, epidural space beneath the skull, intraventricular catheter is thought to be the most accurate, immediate access, a subarachnoid bolt, is not a qualified neurosurgeon to place a bolt, an epidural sensor, to insert an intraventricular catheter a burr hole is drilled, the skull, catheter is inserted, the brain matter, lateral ventricle, contains cerebrospinal fluid, not only, the intracranial pressure, icp, monitored, lowered by draining cerebral spinal fluid, csf, the catheter, catheter difficult to place, increased intracranial pressure, the ventricles change shape under increased pressure, quite small because of the brain expanding around them from injury, swelling, a subarachnoid screw, bolt, hollow screw that is inserted, a hole drilled, in the skull, a hole cut, in the dura mater, epidural sensor, a burr hole drilled, in the skull, over the epidural covering, the epidural lining is not perforated this procedure is less invasive, has the disadvantage of not able to withdraw excess csf, lidocaine, local anesthetic, injected, site, incision, most likely receive a sedative to help relax, first the area is shaved, cleansed, betadine, alcohol, after drying, an incision is made, skin is pulled back, skull is visible, a drill is then, the bone, expose the epidural tissue, an epidural sensor is used, inserted between the skull, epidural tissue, a bolt is used, an incision is made, the dura, arachnoid tissue exposing the subarachnoid space, bolt is screwed, bone, allows, the sensor to record, subdural/subarachnoid space, an intraventricular catheter is used, threaded, the brain matter into one, the lateral ventricles, type of catheter, effective, accurate in its ability to sense intracranial pressure measurements, need this procedure done, hospital, most likely in an intensive care unit, conscious health care provider, explain the procedure, a consent form must be signed, procedure is performed under general anesthesia, feel nothing, wake, anesthesia, feel the normal side effects of anesthesia, plus the discomfort, the incision made in skull, procedure is performed under local anesthesia, fell a prick on scalp, a bee sting, the local anesthetic is injected, feel a tugging sensation, the skin is cut, pulled back to expose the bone, hear a drill sound, they cut, the skull bone, varying amount, time depending on the type of drill that is used, feel a tugging sensation, they suture the skin back together, prescribe mild pain medications, relief, not want to mask neurologic signs, strong pain medications, increased intracranial pressure neurologic deficits, common, this test, procedure is performed to measure the intracranial pressure, at risk, developing injury from increased intracranial pressure, meant, a sterile access, draining excess csf, icp ranges from 1 to 15 mm hg, mm hg = millimeters of mercury, intracranial pressure monitoring, done in cases of severe head injury, after surgeries, tumor, vascular lesion has been removed, repaired, surgical team is concerned, brain swelling, elevated intracranial pressure, treated by draining csf, the catheter, by changing ventilator settings, in critical condition, on a respirator, by the application of certain intravenous medications, intracranial pressure monitoring is crucial in identifying the problem, allowing, immediate treatment, raised intracranial pressure signifies compression of both neural, vascular tissues, left untreated, result in permanent neurologic damage, fatal, infection, bleeding, brain tissue, residual neurologic effects, risks of general anesthesia, inability to locate ventricle, accurately place catheter.
