Noninvasive monitoring of intracranial pressure after cardiac surgery: case report

Abstract

Background: Heart valves are important structures that play an essential role in directing blood flow; changes in the functioning of these structures may require cardiac surgery with cardiopulmonary bypass. The behavior of intracranial pressure (ICP) in patients undergoing this type of surgery is unknown. Objective: aim of this study was to report alterations in the waveform morphology of ICP in a patient submitted to cardiac surgery with cardiopulmonary bypass. Case Description: This report provides data on ICP waveform morphology (P1 and P2 peaks) monitored before, immediately after, and on the 5th day after cardiac surgery. In the preoperative evaluation, the morphology of the patient's ICP waveforms was slightly altered, possibly due to the underlying cardiovascular disease. In the second measurement of the ICP waveforms, performed after surgery, the wave morphology of the ICP was normal. On the 5th PO day, after the patient presented clinical signs of neurological complications, the third ICP measurement was performed, which showed that the morphology of the ICP wave was altered.Conclusions: The use of non-invasive monitoring of ICP is of great importance in patients undergoing cardiac surgery, with the aim of diagnosing, preventing and/or enabling rapid treatment in cases where there is an evolution of more severe neurological complications that may lead to death.

Can a new noninvasive method for assessment of intracranial pressure predict intracranial hypertension and prognosis?

“…Apart from experimental and non-original papers, most of these articles were piloting the use of the device in patients with various neurological and non-neurological conditions. These included cryptococcal meningitis [5], renovascular hypertension [26], pediatric hydrocephalus [2], obesity [8], critical COVID-19 [10], end-stage renal disease [41], pregnancy [19], patients sedated for gastrointestinal endoscopy [24], sedentary chronic stroke patients [40], hemodialysis patients [42], prostatectomy surgery patients [45], fibromyalgia [33], cardiovascular surgery patients [1], diabetes and chronic kidney disease [35], and migraine [14]. To the best of our knowledge, this is the first prospective study to compare the Brain4Care noninvasive method with the invasive gold standard in TBI.…”
