Abstract
BACKGROUND There are pathological conditions in which intracranial hypertension and patent basal cisterns in computed tomography coexist. These situations are not well recognized, which could lead to diagnostic errors and improper management. METHODS We present a retrospective case series of patients with traumatic brain injury, subarachnoid hemorrhage, and cryptococcal meningitis who were treated at our intensive care unit. Criteria for deciding placement of an external lumbar drain were (1) intracranial hypertension refractory to osmotherapy, hyperventilation, neuromuscular blockade, intravenous anesthesia, and, in some cases, decompressive craniectomy and (2) a computed tomography scan that showed open basal cisterns and no mass lesion. RESULTS Eleven patients were studied. Six of the eleven patients treated with controlled lumbar drainage are discussed as illustrative cases. All patients developed intracranial hypertension refractory to maximum medical treatment, including decompressive craniectomy in Four of the eleven cases. Controlled external lumbar drainage led to immediate and sustained control of elevated intracranial pressure in all patients, with good neurological outcomes. No brain herniation, intracranial bleeding, or meningitis was detected during this procedure. CONCLUSIONS Our study provides preliminary evidence that in selected patients who develop refractory intracranial hypertension with patent basal cisterns and no focal mass effect on computed tomography, controlled lumbar drainage appears to be a therapeutic option. In our study there were no deaths or complications. Prospective and larger studies are needed to confirm our results.

Cerebrospinal Fluid Diversion for Refractory Intracranial Hypertension in Traumatic Brain Injury: A Single Center Experience. World Neurosurg 2023; 176:e265-e272. [PMID: 37207724 DOI: 10.1016/j.wneu.2023.05.047] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/27/2023] [Revised: 05/09/2023] [Accepted: 05/10/2023] [Indexed: 05/21/2023]
Abstract
BACKGROUND Diversion of cerebrospinal fluid (CSF) is a common neurosurgical procedure for control of intracranial pressure (ICP) in the acute phase after traumatic brain injury (TBI), where medical management is insufficient. CSF can be drained via an external ventricular drain (EVD) or, in selected patients, via a lumbar (external lumbar drain [ELD]) drainage catheter. Considerable variability exists in neurosurgical practice on their use. METHODS A retrospective service evaluation was completed for patients receiving CSF diversion for ICP control after TBI, from April 2015 to August 2021. Patients were included whom fulfilled local criteria deeming them suitable for either ELD/EVD. Data were extracted from patient notes, including ICP values pre/postdrain insertion and safety data including infection or clinically/radiologically diagnosed tonsillar herniation. RESULTS Forty-one patients were retrospectively identified (ELD = 30 and EVD = 11). All patients had parenchymal ICP monitoring. Both modalities affected statistically significant decreases in ICP, with relative reductions at 1, 6, and 24 hour pre/postdrainage (at 24-hour ELD P < 0.0001, EVD P < 0.01). Similar rates of ICP control failure, blockage and leak occurred in both groups. A greater proportion of patients with EVD were treated for CSF infection than with ELD. One event of clinical tonsillar herniation is reported, which may have been in part attributable to ELD overdrainage, but which did not result in adverse outcome. CONCLUSIONS The data presented demonstrate that EVD and ELD can be successful in ICP control after TBI, with ELD limited to carefully selected patients with strict drainage protocols. The findings support prospective study to formally determine the relative risk-benefit profiles of CSF drainage modalities in TBI.

External Ventricular Drainage: A Practical Guide for Neuro-Anesthesiologists. Clin Pract 2023; 13:219-229.

Abstract
External ventricular drainage is often considered a life-saving treatment in acute hydrocephalus. Given the large number of discussion points, the ideal management of EVD has not been completely clarified. The objective of this study was to review the most relevant scientific evidence about the management of EVD in its main clinical scenarios. We reviewed the most recent and relevant articles about indications, timing, management, and complications of EVD in neurocritical care, with particular interest in patients with subarachnoid hemorrhage (SAH), severe traumatic brain injury (TBI), and intraventricular hemorrhage (IVH) using the following keywords alone or matching with one another: intracranial pressure, subarachnoid hemorrhage, traumatic brain injury, intraventricular hemorrhage, external ventricular drainage, cerebrospinal shunt, intracranial pressure monitoring, and ventriculoperitoneal shunt. In the management of EVD in SAH, the intermittent drainage strategy is burdened with an elevated risk of complications (e.g., clogged catheter, hemorrhage, and need for replacement). There seems to be more ventriculoperitoneal shunt dependency in rapid weaning approach-managed patients than in those treated with the gradual weaning approach. Although there is no evidence in favor of either strategy, it is conventionally accepted to adopt a continuous drainage approach in TBI patients. Less scientific evidence is available in the literature regarding the management of EVD in patients with severe TBI and intraparenchymal/intraventricular hemorrhage. EVD placement is a necessary treatment in several clinical scenarios. However, further randomized clinical trials are needed to clarify precisely how EVD should be managed in different clinical scenarios.

Abstract
Considerable variation exists in the clinical practice of cerebrospinal fluid diversion for medically refractory intracranial hypertension in patients with acute traumatic brain injury (TBI), which is achievable via lumbar or ventricular drainage. This systematic review sought to compile the available evidence for the efficacy and safety of the use of lumbar drains for intracranial pressure (ICP) control. A systematic review of the literature was performed with the search and data extraction performed by two reviewers independently in duplicate. Nine independent studies were identified, enrolling 230 patients, 159 with TBI. Efficacy for ICP control was observed across all studies, with immediate and sustained effect, reducing medical therapy requirements. Lumbar drainage with medical therapy appears effective when used alone and as an adjunct to ventricular drainage. Safety reporting varied in quality. Clinical or radiological incidents of cerebral herniation (with an unclear relationship to lumbar drainage) were observed in 14/230 patients resulting in one incident of morbidity without adverse patient outcome. The available data is generally poor in quality and volume, but supportive of the efficacy of lumbar drainage for ICP control. Few reports of adverse outcomes are suggestive of, but are insufficient to confirm, the safety of use in the appropriate patient and clinical setting. Further large prospective observational studies are required to generate sufficient support of an acceptable safety profile.

Abstract
Neurotrauma, often defined as abrupt damage to the brain or spinal cord, is a substantial cause of mortality and morbidity that is widely recognized. As such, establishing an effective course of action is crucial to the enhancement of neurotrauma guidelines and patient outcomes in healthcare worldwide. Following the onset of neurotraumatic injuries, time is perhaps the most critical facet in diminishing mortality and morbidity rates. Thus, procuring the airway should be of utmost priority in a patient to allow for optimal ventilation, with a shift in focus resorting to surgical interventions after the patient reaches a suitable care facility. In particular, ventriculoperitoneal shunt (VPS) procedures have long been utilized to treat traumatic brain and spinal cord injuries to direct additional cerebrospinal fluid (CSF) from the lateral ventricles through a ventricular catheter attached to a valve that is further connected to a distal catheter. Decompressive cranio omie (DCs), cranioplasties, and intracranial pressure measurements (ICP) are also frequently performed in combination with VPS to manage intracranial hypertension and cerebral edema. Although the current surgical methods utilized in the treatment of neurotrauma prove to be highly efficacious in the prevention of adverse outcomes, emergent therapies are growing in popularity. Of interest, the Three Pillars Expansive Craniotomy, cisternostomy, and external lumbar drainages are cutting-edge procedures with promising results that can potentially usher change in the neurosurgical industry but require additional examination.

Abstract
In this work, we develop a label-free electrochemical immunosensor for the detection of interleukin-6 (IL-6) in human cerebrospinal fluid (CSF) and serum for diagnostic and therapeutic monitoring. The IL-6 immunosensor is fabricated from gold interdigitated electrode arrays (IDEAs) that are modified with IL-6 antibodies for direct antigen recognition and capture. A rigorous surface analysis of the sensor architecture was conducted to ensure high structural fidelity and performance. Electrochemical characterization was conducted by cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS), and sensing was performed using differential pulse voltammetry (DPV). The DPV peak current was used to quantify IL-6 in buffer, CSF, and serum in the range 1 pg mL-1 < [IL-6] < 1 μg mL-1. The IL-6 IDEA sensor achieved a limit of detection (LOD) of 1.63 pg mL-1 in PBS, 2.34 pg mL-1 in human CSF, and 11.83 pg mL-1 in human serum. The sensor response is linear in the concentration range 10 pg mL-1 < [IL-6] < 10 ng mL-1, and the sensor is selective for IL-6 over other common cytokines, including IL-10 and TNF-α. EIS measurements showed that the resistance to charge transfer, R CT, decreases upon IL-6 binding, an observation attributed to a structural change upon Ab-Ag binding that opens up the architecture so that the redox probe can more easily access the electrode surface. The IL-6 IDEA sensor can be used as a point-of-care diagnostic tool to deliver rapid results (∼3 min) in clinical settings for traumatic brain injury, and potentially address the unmet need for effective diagnostic and prognostic tools for other cytokine-related illnesses, such as sepsis and COVID-19 induced cytokine storms. Given the interdigitated electrode form factor, it is likely that the performance of the sensor can be further improved through redox cycling.

Abstract
Objective To analyze the different effects of Continuous Lumbar Drainage of fluid and lumbar puncture drainage for aneurysmal subarachnoid hemorrhage (SAH) after intracranial aneurysm clipping. Method Seventy-five patients with aneurysmal SAH who underwent aneurysm clipping were retrospectively analyzed and were divided into two groups according to the different postoperative drainage methods. The lumbar spine group received lumbar puncture drainage, and the lumbar cistern group received lumbar pool continuous drainage to compare the efficacy. Result The time to normalize intracranial pressure and headache relief after drainage treatment in the lumbar cistern group was shorter than that in the lumbar spine group. The GOS score was higher than that in the lumbar spine group, and the cerebral artery flow velocity and NIHSS score were significantly lower than those in the lumbar spine group (P < 0.05). The total effective rate of drainage treatment was 76.32% in the lumbar cistern group, which was higher than that in the lumbar spine group (54.05%) (P < 0.05). The total complication rate was 18.42% in the lumbar cistern group, which was lower than that in the lumbar spine group (40.54%) (P < 0.05). Conclusion Continuous Lumbar Drainage of fluid after intracranial aneurysm clipping for aneurysmal SAH can control symptoms more rapidly, reduce neurological deficits, and improve prognosis than lumbar puncture. Also, the drainage is safer and more widely used.

Abstract
BACKGROUND Traumatic brain injury (TBI) often results in elevations in intracranial pressure (ICP) that are refractory to standard therapies. Several studies have investigated the utility of external lumbar drainage (ELD) in this setting. OBJECTIVE To evaluate the safety and efficacy of ELD or lumbar puncture with regard to immediate effect on ICP, durability of the effect on ICP, complications, and neurological outcomes in adults with refractory traumatic intracranial hypertension. METHODS A systematic review and meta-analysis were conducted beginning with a comprehensive search of PubMed/EMBASE. Two investigators reviewed studies for eligibility and extracted data. The strength of evidence was evaluated using GRADE methodology. Random-effects meta-analyses were performed to calculate pooled estimates. RESULTS Nine articles detailing 6 studies (N = 110) were included. There was moderate evidence that ELD has a significant immediate effect on ICP; the pooled effect size was -19.5 mmHg (95% CI -21.0 to -17.9 mmHg). There was low evidence to indicate a durable effect of ELD on ICP up to at least 24 h following ELD. There was low evidence to indicate that ELD was safe and associated with a low rate of clinical cerebral herniation or meningitis. There was very low evidence pertaining to neurological outcomes. CONCLUSION Given preliminary data indicating potential safety and feasibility in highly selected cases, the use of ELD in adults with severe TBI and refractory intracranial hypertension in the presence of open basal cisterns and absence of large focal hematoma merits further high-quality investigation; the ideal conditions for potential application remain to be determined.

Abstract
BACKGROUND The Brain Trauma Foundation (BTF) published evidence-based guidelines with a detailed approach to the management of intracranial hypertension (ICH) in traumatic brain injury (TBI) patients. However, management with cerebrospinal fluid (CSF) drainage in TBI patients remains a controversial topic and is a recent addition to the 4th Edition of the BTF guidelines. External lumbar drainage (ELD) has been proposed for the management of patients with refractory ICH despite aggressive measures. ELD has been described in the literature with possible benefits in outcomes; still, many questions remain unanswered. METHODS A systematic search on MEDLINE was conducted for articles that studied lumbar CSF drainage in adult TBI patients with ICH. RESULTS Eleven studies met the inclusion criteria, which included 5 prospective and 6 retrospective studies. Several studies showed that CSF drainage via lumbar drain resulted in significant reduction of ICP compared to before ELD placement and had a low complication rate. However, the data reporting mortality and functional outcomes are varied across studies. CONCLUSION The literature suggests that ELD may play a role in the management of refractory ICH in TBI patients when first and second-tier measures fail and may be a safe, effective, and minimally invasive method to significantly lower ICP. Additional research and standardized treatment protocols are necessary.

Abstract
OBJECTIVE To analyze the dynamic curve of cerebrospinal fluid (CSF)-related indices in cases of postoperative meningitis after selective craniotomy and to provide reference data for the clinical treatment with lumbar cistern drainage (LCD). METHODS We conducted a retrospective study of LCD placement in 51 patients. Primary outcomes measured included dynamic changes of body temperature before and after intervention and cerebrospinal fluid biochemical parameters over the course of 13 days of catheter placement. We also assessed the bivariate correlation between white blood cell (WBC) count changes, polykaryocyte percentage, body temperature, and daily cerebrospinal fluid drainage volume. Finally, we analyzed the effect of average daily drainage volume, antibiotic choice, and surgical site on WBC count change curves. RESULTS After LCD, there was a statistically significant difference (P < 0.01) between the WBC count before drainage and on the fourth day of drainage. There was a negative correlation between the change curve of the WBC count and the change curve of daily drainage volume (r = -0.56). When the daily drainage volume was 250-300 mL/day, the change curve pattern of the WBC count was consistent with the overall trend, and there was no significant difference in the curve of the WBC count between different surgical sites (P > 0.05). CONCLUSIONS The WBC count can decrease significantly by day 4 after drainage, and placement of the LCD for 6-7 days is ideal. An average drainage volume of 250-300 mL/day is safe and effective.

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.
