RESUMEN
PURPOSE: The investigators aimed to understand the unmet needs of adults with cerebral palsy (CP) living in urban South Africa and to ascertain similarities or differences to typically developing (TD) adults in the same community. MATERIALS AND METHODS: Participants were interviewed with an adapted version of the Southampton Needs Assessment Questionnaire (SNAQ). Non-parametric statistical analysis was utilised for quantitative data and qualitative data were analysed using free coding to identify themes. RESULTS: Thirty adults with CP (median age 34.8 years; GMFCS levels I/II/III/IV/V: n = 6/6/5/7/6; socio-economic status (SES) low/average/high: n = 8/17/5) were matched for gender, age, and SES. Adults with CP reported a higher unemployment rate and lower level of satisfaction with access to health services than TD peers. Core themes identified by the participants with CP that made community participation more difficult were physical capacity, poor access to accommodation, transport and health services, lack of socialising opportunities, poor universal design, and lack of financial independence. CONCLUSIONS: Adults with CP reported experiencing many challenges in their communities. Improved access to health care services and transport, and the universal design of housing and community buildings to accommodate individuals with a disability should be made a priority.Implications for rehabilitationAdults with cerebral palsy (CP) reported that their disability had an impact on their social life, home life, and work life.Accessibility issues have been identified as a major factor affecting adults with CP in a variety of areas, including access to and use of health services, housing, transportation, and community buildings.Adults with CP reported the need for support during the transition to adulthood, especially with developing life skills that will promote living independently in the community as adults with disabilities.

BACKGROUND: Although the short-term outcomes of selective dorsal rhizotomy (SDR) in children with cerebral palsy (CP) have been well documented, less is known about the long-term benefits of SDR, especially while aging. RESEARCH QUESTION: Does the gait of adults with CP, who underwent SDR in childhood, change during a nine-year aging follow-up period? Do associations exists between the gait deviation index (GDI) and contextual factors at follow-up? METHODS: Three-dimensional motion data was captured (Vicon system) of 26 adults (10 female) with CP and spastic diplegia at baseline (17-to-26 years post-SDR) and at nine-year follow-up (26-to-35 years post-SDR), as well as 41 matched typically developed (TD) adults used for reference data. Kinematic, non-dimensional temporal distance and GDI parameters were determined, and associations with contextual factors were studied. RESULTS: At follow-up the adults with CP had a (median [interquartile ranges]) age of 35.8 [34.2-41.2] years and classified as Gross Motor Function Classification System (GMFCS) level I (n = 13), level II (n = 10) and level III (n = 3). Overall no clinically relevant change in gait quality (GDI) was detected over the nine-year follow-up period. However, small changes were found in hip and knee range of motion, peak knee flexion and walking speed. In line with the baseline study, a number of gait parameters were different to TD adults. The only association found was between GDI and GMFCS at follow-up (r = 0.64, p < 0.01). SIGNIFICANCE: The overall walking pattern of the adults with CP who underwent SDR in childhood was characterised by mild crouch gait with minimal signs of spasticity, confirming former physical examination findings. Some small changes in certain gait parameters were determined, though clinically the gait quality remained stable during the nine-year aging period. This finding supports the stability of the gait pattern during mid-life in adults with CP, who met the strict SDR selection criteria.

OBJECTIVE: The primary purpose of selective dorsal rhizotomy (SDR) is to ameliorate spasticity in the lower extremities of children with cerebral palsy (CP). In correctly selected patients, this neurosurgical procedure has been shown to have a beneficial effect on many aspects of the child's life. However, given the challenges faced by adults with CP, it would be valuable to document the status of this population compared to their peers later in adulthood. Therefore, the aim of this study was to determine the physical status, mental health, and health-related quality of life (HRQoL) of adults with CP who underwent SDR at least 25 years ago, compared to matched typically developing (TD) individuals. The second aim was to investigate relationships between physical status and the other outcome measures. METHODS: Adults with CP were recruited from a database of children who had undergone SDR performed using the technique introduced by Professor Warwick Peacock at Red Cross War Memorial Children's Hospital in Cape Town, South Africa, between 1981 and 1991. These individuals were matched for age, sex, body mass index, and socioeconomic status to a TD adult cohort from a similar background. The parameters assessed were lower-extremity muscle tone, passive range of motion, muscle strength, selectivity, functional mobility and dynamic balance (Timed Up and Go [TUG] test), HRQoL (SF-36), and anxiety and depression levels. RESULTS: Twenty-six adults with CP who had a median age of 35.8 years (interquartile range 34.2-41.4 years) (female/male: n = 10/16; Gross Motor Function Classification System level I/II/III: n = 13/10/3), were compared to 26 TD adults. Muscle tone was similar, whereas passive range of motion, muscle strength, selectivity, TUG, and SF-36 physical functioning (concept and summary) scores differed between the cohorts. Other SF-36 parameters, anxiety levels, and depression levels were not different. Strong correlations were found between the muscle strength and TUG scores. CONCLUSIONS: Normalized lower-extremity muscle tone was sustained 25-35 years after SDR. Whereas the lower scores for physical assessments are in line with findings in other CP populations, remarkably, relatively good mental health and HRQoL scores were reported in this CP group despite their physical limitations. The strong correlation between muscle strength and TUG suggests that strength training after SDR may have value in improving functional mobility and balance.

Background: Research in high income countries shows that people with cerebral palsy (CP) are less physically active than typically developing (TD) peers, but less is known regarding physical activity (PA) in those with CP in low-to-middle income countries. The aim of this study was to determine daily step count and levels of PA in adolescents and adults with CP living in urban South Africa, compared to TD peers, and to determine associations with sex, Gross Motor Function Classification System (GMFCS) level, body mass index and socio-economic status. Materials and Methods: This case-control study included 26 adolescents and 22 adults with CP (GMFCS Level I-V) and matched TD peers (25 and 30, respectively). Participants wore an ActiGraph GT3X for 7 consecutive days to determine step count and time (minutes per hour) spent in PA levels, including sedentary (SED), low physical activity (LPA) and moderate to vigorous physical activity (MVPA). Results: The daily step count and PA levels for ambulant adolescents with CP (GMFCS level I-III) were similar to TD peers, while this was less for adolescents classified in GMFCS level IV-V. Daily step count, SED and MVPA were similar for adults classified in GMFCS level I-II compared to TD adults, while all parameters were lower for adults using assistive devices (GMFCS level III) and non-ambulant adults (GMFCS level IV-V) compared to TD peers. Daily step count and PA levels were inversely associated with GMFCS, while no other associations were found. Conclusion: People with CP who were more mobile dependent (higher GMFCS level) were less active. However, adolescents and adults with CP classified as GMFCS levels I-II living in urban South Africa recorded similar step count and PA levels as their TD peers. This was also the case for adolescents using assistive devices, though not for those in the adult group (GMFCS level III). Furthermore, it was apparent that even the ambulant individuals with CP and TD cohorts were relatively inactive. Intervention programs for CP and TD adolescents should be aimed at finding strategies to keep adolescents physically active well into adulthood, in order to promote physical health, social and emotional well-being and independence.
RESUMEN
PURPOSE: To determine changes in level of accomplishment and satisfaction in daily activities and social participation, and functional mobility in adults with cerebral palsy (CP) more than 25 years after selective dorsal rhizotomy (SDR). MATERIALS AND METHODS: This long-term observational nine-year follow-up study included 26 adults (median age 35 years) with CP and spastic diplegia, and 26 matched typically developing adults. Assessment tools used were the Life-Habits questionnaire and the Functional Mobility Scale. RESULTS: Most of the adults with CP were independent and satisfied with accomplishing life habits and no changes were determined, except for a small change in the Housing accomplishment level. Compared to typically developing adults, the CP cohort was more dependent in accomplishing Mobility and Recreation. However, the level of satisfaction was similar for most life habits except for Mobility. Functional mobility did not change, but correlated with Life-Habits results. CONCLUSIONS: Adults with CP showed high and stable levels of accomplishment and satisfaction in daily activities and social participation more than 25 years after SDR. This is in contrast with the literature, where functional decline was shown for individuals with CP as they age. The relation with functional mobility highlights the importance to focus the rehabilitation on maintaining walking ability in order to enable high level of daily activities and social participation in adults with CP.Implications for rehabilitationSelective dorsal rhizotomy (SDR) is a valuable treatment option for a selective group of children with cerebral palsy (CP) in order to reduce spasticity.The long-term outcomes of SDR on level of accomplishment and satisfaction in daily activities and social participation as well functional mobility in adults with CP are not clear.More than 25 years after SDR adults with CP experienced stable and lasting high levels of functioning regarding daily activities and social participation and were satisfied with the way they accomplished life habits.Functional mobility was correlated to level of accomplishment and satisfaction in daily activities and social participation, which highlights the importance to focus rehabilitation programs on maintaining functional mobility in order to enable daily activities and social participation in adults with CP.

OBJECTIVE: The main purpose of selective dorsal rhizotomy (SDR) is to reduce spasticity in the lower extremities of children diagnosed with cerebral palsy (CP) and spastic diplegia. The potential for developing spinal abnormalities and pain is a concern, especially in the aging CP population. Therefore, the aim of this study was to evaluate spinal abnormalities, level of pain, and disability (due to back or leg pain) in adults with CP, and associations with participant characteristics, more than 25 years after SDR. METHODS: This is a 9-year follow-up study with data collection conducted in 2008 and 2017. Radiographs were assessed for the degree of scoliosis, thoracic kyphosis and lumbar lordosis curvatures, and prevalence of spondylolysis and spondylolisthesis, while level of pain and disability was determined with a self-developed questionnaire and the Oswestry Disability Index (ODI) questionnaire, respectively. RESULTS: Twenty-five participants were included (15 males; median age 35.9 years, IQR 34.3-41.5 years), with a follow-up time after SDR ranging from 25 to 35 years. No clinically relevant changes were found for spinal curvatures, spondylolysis and spondylolisthesis, perceived pain frequency, and ODI scores between 2008 and 2017. While the prevalence of spondylolysis was 44%, spondylolisthesis was found in 20% (of whom 15% were grade I and 5% grade II), lumbar hyperlordosis was found in 32%, thoracic hyperkyphosis in 4%, and scoliosis in 20%. The Cobb angle was < 25°, and no patient required surgery for scoliosis. In addition, the low back was reported as the most common site of pain, with 28% of the adults with CP having daily pain. This resulted in 80% of the cohort indicating none or minimal disability due to pain based on the ODI. The only correlation found was between hyperkyphosis and female gender. CONCLUSIONS: At follow-up more than 25 years after SDR, no progression in spinal abnormalities, level of pain, and disability was found when compared with findings 15 years after SDR. The prevalence of scoliosis, thoracic hyperkyphosis, and lumbar hyperlordosis was within the range reported for adults with CP, while spondylolysis and spondylolisthesis occurred more often than would be expected. It is difficult, however, to establish the role of SDR in this finding, given the limited data on the natural history of CP. Despite the encouraging outcome of this long-term follow-up study after SDR, it is important to continue monitoring adults with CP during the aging process.
RESUMEN
BACKGROUND: Hydrocephalus is a common, life threatening complication of human immunodeficiency virus (HIV)-related central nervous system opportunistic infection which can be treated by insertion of a ventriculoperitoneal shunt (VPS). In HIV-infected patients there is concern that VPS might be associated with unacceptably high mortality. To identify prognostic indicators, we aimed to compare survival and clinical outcome following VPS placement between all studied causes of hydrocephalus in HIV infected patients. METHODS: The following electronic databases were searched: The Cochrane Central Register of Controlled Trials, MEDLINE (PubMed), EMBASE, CINAHL Plus, LILACS, Research Registry, the metaRegister of Controlled Trials, ClinicalTrials.gov, African Journals Online, and the OpenGrey database. We included observational studies of HIV-infected patients treated with VPS which reported of survival or clinical outcome. Data was extracted using standardised proformas. Risk of bias was assessed using validated domain-based tools. RESULTS: Seven Hunderd twenty-three unique study records were screened. Nine observational studies were included. Three included a total of 75 patients with tuberculous meningitis (TBM) and six included a total of 49 patients with cryptococcal meningitis (CM). All of the CM and two of the TBM studies were of weak quality. One of the TBM studies was of moderate quality. One-month mortality ranged from 62.5-100% for CM and 33.3-61.9% for TBM. These pooled data were of low to very-low quality and was inadequate to support meta-analysis between aetiologies. Pooling of results from two studies with a total of 77 participants indicated that HIV-infected patients with TBM had higher risk of one-month mortality compared with HIV non-infected controls (odds ratio 3.03; 95% confidence-interval 1.13-8.12; p = 0.03). CONCLUSIONS: The evidence base is currently inadequate to inform prognostication in VPS insertion in HIV-infected patients. A population-based prospective cohort study is required to address this, in the first instance.

PURPOSE: The purpose of this study was to determine the incidence of spinal deformities in ambulant adults with cerebral palsy (CP) and spastic diplegia, more than 15 years after orthopaedic interval surgery approach (ISA) treatment, and its relationship to contextual factors, level of pain and physical status. METHODS: Spinal X-rays, pain (Oswestry Disability Index (ODI) and location/frequency) questionnaires and physical examination assessing lower extremity muscle strength (Medical Research Council scale), motor control (selectivity scale) and muscle tone (Ashworth score) were conducted in 30 adults with spastic diplegic CP. RESULTS: Mild scoliosis (curve 12-22°) was determined in eight (28%) participants. Hyperkyphosis (> 50°) was reported in two (7%) and lumbar hyperlordosis (> 60°) in five (17%) participants. Pain was most commonly reported at cervical (n = 19, 63%) and lumbosacral (n = 18, 60%) area, resulting in 'moderate disability' for six (20%) and 'severe disability' for one (3%) participant. Most apparent physical abnormalities determined were hip abduction weakness and increased rectus femoris muscle tone. Regarding correlations, no relations were found for scoliosis curvature, but kyphosis curvature was related to females, ODI scores (lifting and sitting) and increased muscle tone of ankle plantar flexor muscles, lordosis curvature to passive hip extension mobility, and hip flexors and ankle plantar flexors muscle tone. CONCLUSION: Adults with spastic diplegic CP who received their first orthopaedic intervention more than 15 years ago (based on ISA) showed similar incidence of spinal deformities as reported in the younger CP population, suggesting stability of spinal curvature into adulthood.

BACKGROUND: Single-event multilevel surgery (SEMLS) approach is regarded as the golden standard in developed countries to improve gait and functional mobility in children with cerebral palsy (CP). However, this approach is not always feasible in developing countries. Therefore, orthopedic surgery based on an interval surgery approach (ISA) is still commonly used in developing countries, although little is known about the long term outcomes of an ISA. Therefore, the aim of this study was to describe the gait patterns of adults with CP, who have been treated with ISA, which started more than 15 years ago. MATERIALS AND METHODS: Thirty adults with CP and spastic diplegia, who received ISA treatment 21.6-33.7 years ago, were recruited for this study and participated in three-dimensional gait analysis. Twenty kinematic and nondimensional temporal-distance parameters were captured, while the overall gait deviation index (GDI) was also calculated. Data of the adults with CP were compared to normative data of typically developing (TD) adults. RESULTS: Although all adults with CP were still ambulant, their gait parameters significantly differed from TD adults, with a lower GDI in the adults with CP. The CP gait patterns were characterized by excessive hip flexion and hip internal rotation as well as a stiff-knee gait. CONCLUSION: Although different to TD adults, the gait patterns observed in the adult with CP treated with ISA is in line with other studies. Gait patterns suggest that derotation osteotomies potentially could have improved the long term gait patterns. Although SEMLS might be the preferred treatment method, potentially resulting in better outcomes, ISA can also be used to treat children with CP in developing countries as India and South Africa, where a SEMLS approach is not always feasible.
RESUMEN
BACKGROUND: Hydrocephalus is a recognised complication of human immunodeficiency virus (HIV)-related opportunistic infections. Symptomatic raised cerebrospinal fluid pressure can be treated with ventriculoperitoneal shunt insertion (VPS). In HIV-infected patients however, there is a concern that VPS might be associated with unacceptably high rates of mortality. We aim to systematically review and appraise published literature to determine reported outcomes and identify predictors of outcome following VPS in relevant subgroups of HIV-infected adults. METHODS: The following electronic databases will be searched: The Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE (PubMed), EMBASE, CINAHL (EBSCOhost), LILACS (BIREME), Research Registry ( www.researchregistry.com ), the metaRegister of Controlled Trials (mRCT) ( www.controlled-trials.com ), ClinicalTrials.gov ( www.clinicaltrials.gov ) and OpenSIGLE database. Any randomised studies, cohort studies, case-control studies, interrupted time series or sequential case series reporting survival following VPS in HIV-infected individuals will be included. If high-quality homogenous studies exist, meta-analysis will be conducted to determine 1-, 6- and 12-month mortality with comparison made between underlying aetiologies of hydrocephalus. DISCUSSION AND CONCLUSION: This study will generate a comprehensive review of VPS in HIV-infected patients for publication. The primary outcome of meta-analysis is 12-month survival. If only low-quality, heterogeneous studies are available, this study will demonstrate this deficiency and will be of value in justifying and aiding the design of future studies.

PURPOSE: To analyse the diagnostic accuracy of age-related optic nerve sheath diameter (ONSD) cut-off values in children for detecting raised intracranial pressure (ICP) and to assess the benefit of using patency of the anterior fontanelle in describing a different set of cut-off values. METHODS: The ONSD measurement was performed prior to invasive ICP measurement in children under general anesthesia. The diagnostic accuracy of the ONSD measurement was compared to ICP at thresholds of 20, 15, 10, and 5 mmHg. This was further analysed in children above and below the age of 1 year, with a subgroup analysis of age at 4 years, and assessment of the anterior fontanelle (AF) as a reliable physiological marker in part II of this study. RESULTS: Data from 174 children were analysed. In children ≤1 year old, the ONSD measurement with the best diagnostic accuracy for detecting ICP ≥ 20 mmHg was 5.16 mm, compared to 5.75 mm in children >1 year old (p < 0.001). In addition, patency of the anterior fontanelle (AF) was found to be a useful clinical marker for defining different ONSD cut-off values at ICP thresholds of 20, 15, 10 and 5 mmHg. CONCLUSION: Transorbital ultrasound measurement of the ONSD is a reliable non-invasive marker of ICP particularly at higher thresholds of 20 and 15 mmHg. Patency of the AF is a useful clinical marker for defining different ONSD cut-off values in children.

PURPOSE: The aim of this study was to investigate the relationship between optic nerve sheath diameter (ONSD) measurement and invasively measured intracranial pressure (ICP) in children. METHODS: ONSD measurement was performed prior to invasive measurement of ICP. The mean binocular ONSD measurement was compared to the ICP reading. Physiological variables including systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), pulse rate, temperature, respiratory rate and end tidal carbon dioxide (ETCO2) level were recorded at the time of ONSD measurement. Diagnostic accuracy analysis was performed at various ICP thresholds and repeatability, intra- and inter-observer variability, correlation between measurements in different imaging planes as well the relationship over the entire patient cohort were examined in part I of this study. RESULTS: Data from 174 patients were analysed. Repeatability and intra-observer variability were excellent (α = 0.97-0.99). Testing for inter-observer variability revealed good correlation (r = 0.89, p < 0.001). Imaging in the sagittal plane demonstrated a slightly better correlation with ICP (r = 0.66, p < 0.001). The ONSD measurement with the best diagnostic accuracy for detecting an ICP ≥ 20 mmHg over the entire patient cohort was 5.5 mm, sensitivity 93.2 %, specificity 74 % and odds ratio (OR) of 39.3. CONCLUSION: Transorbital ultrasound measurement of the OSND is a reliable and reproducible technique, demonstrating a good relationship with ICP and high diagnostic accuracy for detecting raised ICP.

AIM: Information regarding the selection procedure for selective dorsal rhizotomy (SDR) in children with spastic cerebral palsy (CP) is scarce. Therefore, the aim of this study was to summarize the selection criteria for SDR in children with spastic CP. METHOD: A systematic review was carried out using the following databases: MEDLINE, CINAHL, EMBASE, PEDro, and the Cochrane Library. Additional studies were identified in the reference lists. Search terms included 'selective dorsal rhizotomy', 'functional posterior rhizotomy', 'selective posterior rhizotomy', and 'cerebral palsy'. Studies were selected if they studied mainly children (<18y of age) with spastic CP, if they had an intervention of SDR, if they had a detailed description of the selection criteria, and if they were in English. The levels of evidence, conduct of studies, and selection criteria for SDR were scored. RESULTS: Fifty-two studies were included. Selection criteria were reported in 16 International Classification of Functioning, Disability and Health model domains including 'body structure and function' (details concerning spasticity [94%], other movement abnormalities [62%], and strength [54%]), 'activity' (gross motor function [27%]), and 'personal and environmental factors' (age [44%], diagnosis [50%], motivation [31%], previous surgery [21%], and follow-up therapy [31%]). Most selection criteria were not based on standardized measurements. INTERPRETATION: Selection criteria for SDR vary considerably. Future studies should describe clearly the selection procedure. International meetings of experts should develop more uniform consensus guidelines, which could form the basis for selecting candidates for SDR.

Endoscopy for hydrocephalus caused by infectious diseases presents clear challenges to the surgeon. Hydrocephalus caused by tuberculous meningitis is a good model to explore many of the issues that should be considered in the management of these patients. Tuberculous hydrocephalus may be communicating or noncommunicating management options include medical treatment (for communicating hydrocephalus), ventriculoperitoneal shunting, and endoscopic third ventriculostomy. No guidelines exist currently, and therefore management protocols are specific to each center. Because brain ischemia attributable to vasculitis is common in these patients, optimal treatment of intracranial pressure (ICP) is even more important than usual, and this has implications for the management decisions. Effective treatment of these patients should lead to normalization of ICP and resolution of the hydrocephalus, rather than merely avoiding extreme elevations of ICP. However, this also must be weighed against the surgical and long-term complications associated with the procedures used. There are specific endoscopic challenges that occur as the result of abnormal anatomy and the fact that hydrocephalus presents during the acute phase of the disease, rather than being postinfectious. In this article we examine the arguments for various therapeutic approaches and discuss the gathering experience in the literature about endoscopy in tuberculous meningitis in the context of overall management options.

The purpose of this study was to use three-dimensional gait analysis to describe the gait status of adults with spastic diplegia who underwent selective dorsal rhizotomy (SDR) in childhood. Outcome measures were the gait deviation index (GDI), non-dimensional temporal-distance parameters, and kinematics of the lower limbs. A total of 31 adults with spastic diplegia who had previously undergone SDR were eligible and participated in current study (SDR group). These participants had a median age of 26.8 years (range 21-44 years) with a mean time between surgery and assessment of 21.2±2.9 years (range 17-26 years). For comparison purposes, 43 typically developed adults also participated (CONTROL group), with a median age of 28.3 years (range 21-45 years). More than 17 years after SDR 58% of the SDR group showed improved GMFCS levels, while none of them deteriorated. The participants in the SDR group walked with a mild crouch gait, although there was a loading response, adequate swing-phase knee flexion, adequate swing-phase plantarflexion, reasonable speed and cadence. The gait status of the SDR group more than 17 years after SDR was similar to what has been reported in short-term follow-up studies, as well as our earlier 20 year follow-up study that did not include 3D gait analysis. Appropriate orthopaedic intervention was required in 61% of the study cohort. Whether the types and numbers of orthopaedic interventions are positively affected by SDR remains an open question. Further studies examining this question are warranted. In addition, long-term follow-up studies focused on other interventions would also be of clinical relevance.

BACKGROUND: Intracranial pressure (ICP) monitoring is a cornerstone of care for severe traumatic brain injury (TBI). Management of ICP can help ensure adequate cerebral blood flow and oxygenation. However, studies indicate that brain hypoxia may occur despite normal ICP and the relationship between ICP and brain oxygenation is poorly defined. This is particularly important for children in whom less is known about intracranial dynamics. OBJECTIVE: To examine the relationship between ICP and partial pressure of brain tissue oxygen (PbtO2) in children with severe TBI (Glasgow Coma Scale score ≤ 8) admitted to Red Cross War Memorial Children's Hospital, Cape Town. METHODS: The relationship between time-linked hourly and high-frequency ICP and PbtO2 data was examined using correlation, regression, and generalized estimating equations. Thresholds for ICP were examined against reduced PbtO2 using age bands and receiver-operating characteristic curves. RESULTS: Analysis using more than 8300 hourly (n = 75) and 1 million high-frequency data points (n = 30) demonstrated a weak relationship between ICP and PbtO2 (r = 0.05 and r = 0.04, respectively). No critical ICP threshold for low PbtO2 was identified. Individual patients revealed a strong relationship between ICP and PbtO2 at specific times, but different relationships were evident over longer periods. CONCLUSION: The relationship between ICP and PbtO2 appears complex, and several factors likely influence both variables separately and in combination. Although very high ICP is associated with reduced PbtO2, in general, absolute ICP has a poor relationship with PbtO2. Because reduced PbtO2 is independently associated with poor outcome, a better understanding of ICP and PbtO2 management in pediatric TBI seems to be needed.
