[PMID: 37170383 PMCID: PMC10176793 DOI: 10.1186/s41016-023-00327-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/31/2022] [Accepted: 04/24/2023] [Indexed: 05/13/2023] Open
Abstract
Intracranial pressure (ICP) is one of the most important indexes in neurosurgery. It is essential for doctors to determine the numeric value and changes of ICP, whether before or after an operation. Although external ventricular drainage (EVD) is the gold standard for monitoring ICP, more and more novel monitoring methods are being applied clinically.Invasive wired ICP monitoring is still the most commonly used in practice. Meanwhile, with the rise and development of various novel technologies, non-invasive types and invasive wireless types are gradually being used clinically or in the testing phase, as a complimentary approach of ICP management. By choosing appropriate monitoring methods, clinical neurosurgeons are able to obtain ICP values safely and effectively under particular conditions.This article introduces diverse monitoring methods and compares the advantages and disadvantages of different monitoring methods. Moreover, this review may enable clinical neurosurgeons to have a broader view of ICP monitoring.

Noninvasive real-time assessment of intracranial pressure after traumatic brain injury based on electromagnetic coupling phase sensing technology. BMC Neurol 2021; 21:26. [PMID: 33455585 PMCID: PMC7812649 DOI: 10.1186/s12883-021-02049-3] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2020] [Accepted: 01/07/2021] [Indexed: 12/16/2022] Open
Abstract
Background To investigate the feasibility of intracranial pressure (ICP) monitoring after traumatic brain injury (TBI) by electromagnetic coupling phase sensing, we established a portable electromagnetic coupling phase shift (ECPS) test system and conducted a comparison with invasive ICP. Methods TBI rabbits’ model were all synchronously monitored for 24 h by ECPS testing and invasive ICP. We investigated the abilities of the ECPS to detect targeted ICP by feature extraction and traditional classification decision algorithms. Results The ECPS showed an overall downward trend with a variation range of − 13.370 ± 2.245° as ICP rose from 11.450 ± 0.510 mmHg to 38.750 ± 4.064 mmHg, but its change rate gradually declined. It was greater than 1.5°/h during the first 6 h, then decreased to 0.5°/h and finally reached the minimum of 0.14°/h. Nonlinear regression analysis results illustrated that both the ECPS and its change rate decrease with increasing ICP post-TBI. When used as a recognition feature, the ability (area under the receiver operating characteristic curve, AUCs) of the ECPS to detect ICP ≥ 20 mmHg was 0.88 ± 0.01 based on the optimized adaptive boosting model, reaching the advanced level of current noninvasive ICP assessment methods. Conclusions The ECPS has the potential to be used for noninvasive continuous monitoring of elevated ICP post-TBI.

Brain Behav 2020; 10:e01756. [PMID: 32810378 PMCID: PMC7507080 DOI: 10.1002/brb3.1756] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/04/2020] [Revised: 06/22/2020] [Accepted: 06/28/2020] [Indexed: 12/17/2022] Open
Abstract
OBJECTIVE The present study was conducted to explore the effect of neuroendoscopic hematoma evacuation in severe intraventricular hemorrhage (IVH). METHODS Totally 81 patients with severe IVH in our hospital from November 2017 to March 2019 were divided into the intervention group (38 cases who received neuroendoscopic hematoma evacuation combined with intraventricular lavage) and the control group (40 cases who received trepanation drainage). The perioperative condition, hematoma clearance rate, Glasgow coma score (GCS), hematoma recurrence rate, and prognosis were observed and compared between the two groups after treatment. RESULTS The operative time, time of cerebrospinal fluid drainage, and intracranial infection rate in the intervention group elicited superior results to those in the control group (p < .05). The clearance rate of hematoma in the intervention group was higher than that in the control group at 6 hr, 1, 3, and 7 days postoperatively (p < .05). The postoperative 3- and 7-day GCS scores in the intervention group were higher than those in the control group, and the recurrence rate of hematoma in the intervention group was significantly lower than that in the control group (p < .05), and the good/excellent rate of ADL in the intervention group was significantly higher than that in the control group (p < .05). CONCLUSION Neuroendoscopic hematoma evacuation combined with intraventricular lavage showed evident beneficial outcomes in patients with severe IVH. It can effectively improve the perioperative condition and improve the hematoma clearance rate and is beneficial to the prognosis of patients with severe IVH.

Med Sci Monit 2019; 25:9776-9785.

Abstract
Background In the past, standard rapid decompressive craniectomy was used to alleviate the secondary damage caused by high intracranial pressure. Recent clinical studies showed that controlled decompression may have a better curative effect than rapid decompression. However, the effect on controlled decompression in animals is unclear. Material/Methods Totally 80 healthy male New Zealand rabbits were randomly divided into a sham group (n=20), a rapid decompression group (n=30), and a controlled decompression group (n=30). An intracranial hypertension model was induced by injecting saline into an epidural balloon catheter and reducing ICP slowly and gradually by use of a pressure pump. The model was evaluated and analyzed by general observations, imaging examination, ICP values, behavioral score, brain water content, Nissl staining, and caspase-3 protein detection. Results The mortality rate was 36.7% (11/30) in the rapid group, 20% (6/30) in the controlled group, and 5% (1/20) in the sham group. The incidence of epidural hematoma in the controlled group was lower than in the rapid group (p<0.01). The ICP was significantly lower in the controlled group than in the rapid group (p<0.001), and the behavioral score in the rapid group was higher than in the controlled group (p<0.05). There was a marked difference in brain water content between the controlled group and the rapid group (p<0.01). Nissl staining demonstrated that the ratio of Nissl body in the controlled group was significantly higher than in the rapid group (p<0.01). WB detection showed the expression of Caspase-3 in the controlled group was lower than in the rapid group (p<0.05). Conclusions The results show the advantages of use of controlled decompression with intracranial hypertension. The animal model we developed provides a platform for further research on controlled decompression.
