“…The concept of TCD-based CPPopt may be of question as well, since CPP currently requires ICP to obtain. However, efforts are ongoing for non-invasive TCD-based methods of CPP measurement [ 7 , 8 , 15 , 21 , 26 , 27 ]. With the acquisition of extended duration uninterrupted robotic TCD recordings, the potential to have a more continuous TCD-based CPP measure is feasible, though further research is required.…”

Optimal cerebral perfusion pressure via transcranial Doppler in TBI: application of robotic technology

2018

Individualized cerebral perfusion pressure (CPP) targets may be derived via assessing the minimum of the parabolic relationship between an index of cerebrovascular reactivity and CPP. This minimum is termed the optimal CPP (CPPopt), and literature suggests that the further away CPP is from CPPopt, the worse is clinical outcome in adult traumatic brain injury (TBI). Typically, CPPopt estimation is based on intracranial pressure (ICP)-derived cerebrovascular reactivity indices, given ICP is commonly measured and provides continuous long duration data streams. The goal of this study is to describe for the first time the application of robotic transcranial Doppler (TCD) and the feasibility of determining CPPopt based on TCD autoregulation indices.Electronic supplementary materialThe online version of this article (10.1007/s00701-018-3687-5) contains supplementary material, which is available to authorized users.

“…In developing countries where malaria is endemic, invasive catheter monitoring cannot be sustained due to high cost, need for highly skilled personnel, and its various complications. [ 4 6 ] Assessment by imaging and clinical examination is as effective as invasive catheter monitoring. In a large clinical trial that compared management of traumatic brain injury guided by catheter monitoring of ICP vs. care guided by brain edema assessment by imaging (plus clinical assessment), mortality was not different between the two groups.…”

“…[ 4 ] Many noninvasive methods for estimating ICP have been developed and some of them offer promise for use in clinical practice. [ 6 ] Methods involving brain imaging offer an added advantage of detecting other pathological processes that may complicate CM including infarcts, bleeds, fluid collections, sinusitis, and otomastoiditis.…”

Noninvasive measures of brain edema predict outcome in pediatric cerebral malaria

Background:Increased brain volume (BV) and subsequent herniation are strongly associated with death in pediatric cerebral malaria (PCM), a leading killer of children in developing countries. Accurate noninvasive measures of BV are needed for optimal clinical trial design. Our objectives were to examine the performance of six different magnetic resonance imaging (MRI) BV quantification measures for predicting mortality in PCM and to review the advantages and disadvantages of each method.Methods:Receiver operator characteristics were generated from BV measures of MRIs of children admitted to an ongoing research project with PCM between 2009 and 2014. Fatal cases were matched to the next available survivor. A total of 78 MRIs of children aged 5 months to 13 years (mean 4.0 years), of which 45% were males, were included.Results:Areas under the curve (AUC) with 95% confidence interval on measures from the initial MRIs were: Radiologist-derived score = 0.69 (0.58–0.79; P = 0.0037); prepontine cistern anteroposterior (AP) dimension = 0.70 (0.56–0.78; P = 0.0133); SamKam ratio [Rt. parietal lobe height/(prepontine AP dimension + fourth ventricle AP dimension)] = 0.74 (0.63–0.83; P = 0.0002); and global cerebrospinal fluid (CSF) space ascertained by ClearCanvas = 0.67 (0.55–0.77; P = 0.0137). For patients with serial MRIs (n = 37), the day 2 global CSF space AUC was 0.87 (0.71–0.96; P < 0.001) and the recovery factor (CSF volume day 2/CSF volume day 1) was 0.91 (0.76–0.98; P < 0.0001). Poor prognosis is associated with radiologist score of ≥7; prepontine cistern dimension ≤3 mm; cisternal CSF volume ≤7.5 ml; SamKam ratio ≥6.5; and recovery factor ≤0.75.Conclusion:All noninvasive measures of BV performed well in predicting death and providing a proxy measure for brain volume. Initial MRI assessment may inform future clinical trials for subject selection, risk adjustment, or stratification. Measures of temporal change may be used to stage PCM.

“…[10][11][12][13]16,18,[21][22][23] Patients may be at heightened risk of increasing ICP during anesthesia and surgery for several reasons. [24][25][26][27][28][29][30][31][32][33] Therefore, non-invasive methods, which can easily be applied in the operating room, have gained interest. Transocular ultrasound optic nerve sheath diameter (ONSD) measurement is the most prominent of these methods.…”

“…Transocular ultrasound optic nerve sheath diameter (ONSD) measurement is the most prominent of these methods. [26][27][28][29][30][31][32][33][34][35][36] When ICP increases, the sheath diameter is enlarged, and this change in diameter allows ICP to be evaluated indirectly by ultrasound via the optic nerve sheath. 28 This study aimed to investigate the effects of 3 different laryngoscopes (the McCoy, and Macintosh laryngoscopes and the C-MAC® video-laryngoscope) on laryngoscopy, ONSD, intubation and hemodynamic response in patients with normal airways.…”

This study aims to investigate the effect of McCoy, Macintosh laryngoscope, and C-MAC videolaryngoscopes on optic nerve sheath diameter (ONSD) and hemodynamic responses to laryngoscopy and intubation. Methods: This prospective randomized study was conducted in Zonguldak Bülent Ecevit University Hospital, Zonguldak, Turkey, between July 2019 and January 2020. Informed written consent was obtained from all patients. Patients with previous intracranial/ ocular surgery or glaucoma were excluded from the study. The patients were randomized to use McCoy, Original Article Macintosh, and C-MAC (30 per group). Intubations were performed by the same person. Mean arterial pressure, heart rate (HR), and ONSD were recorded before the induction and repeated in 1, 3, 5, and 10 minutes after the intubation. Results: The effects of laryngoscopy and intubation on hemodynamic responses and ONSD were similar between groups (p>0.05). While the comparison within groups showed ONSD increase in McCoy group and HR and ONSD increase in the Macintosh group compared to baseline 1 min after the intubation, no change was observed in hemodynamic responses and ONSD measurements in the C-MAC® group (p>0.05). Conclusions: In this study, there was no significant difference between the groups in terms of ONSD and hemodynamic responses to laryngoscopy and intubation. It was observed that there were no significant changes in ONSD values just in C-MAC® video-laryngoscope group. Therefore, intubations with C-MAC® videolaryngoscope are thought to be more appropriate for patients with an increase in intracranial pressure.
