Sedation And Analgesia

AbstractMaintaining an adequate level of sedation and analgesia plays a key role in the management of traumatic brain injury (TBI). To date, it is unclear which drug or combination of drugs is most effective in achieving these goals. Ketamine is an agent with attractive pharmacological and pharmacokinetics characteristics. Current evidence shows that ketamine does not increase and may instead decrease intracranial pressure, and its safety profile makes it a reliable tool in the prehospital environment. In this point of view, we discuss different aspects of the use of ketamine in the acute phase of TBI, with its potential benefits and pitfalls.

Abstract PurposeDecompressive craniectomy (DC) can rapidly reduce intracranial pressure and save lives in the acute phase of severe traumatic brain injury (TBI) or stroke, but little is known about the long-term outcome after DC. We evaluated quality of life (QoL) a few years after DC for severe TBI/stroke.MethodsThe following data were collected for stroke/TBI patients hospitalized for neurorehabilitation after DC: 1) at discharge, motor and cognitive sub-scores of the Functional Independence Measure (motor-FIM [score 13-91] and cognitive-FIM [score 5-35]) and 2) more than 4 years after discharge, the QOLIBRI health-related QoL (HR-QoL) score (0-100; <60 representing low or impaired QoL) and the return to work (RTW: 0%, partial, 100%)ResultsWe included 88 patients (66 males, median age 38 [interquartile range 26.3-51.0], 65 with TBI/23 stroke); 46 responded to the HR-QoL questionnaire. Responders and non-responders had similar characteristics (age, sex, functional levels upon discharge). Median motor-FIM and cognitive-FIM scores were 85/91 and 27/35, with no significant difference between TBI and stroke patients. Long-term QoL was borderline low for TBI patients and within normal values for stroke patients (score 58.0[42.0-69.0] vs. 67.0[54.0-81.5], p=0.052). RTW was comparable between the groups (62% full time).ConclusionWe already knew that DC can save the lives of TBI or stroke patients in the acute phase and this study suggests that their long-term quality of life is generally quite acceptable.

Abstract Objective: We examined whether intraindividual variability (IIV) across tests of executive functions (EF-IIV) is elevated in Veterans with a history of mild traumatic brain injury (mTBI) relative to military controls (MCs) without a history of mTBI. We also explored relationships among EF-IIV, white matter microstructure, and posttraumatic stress disorder (PTSD) symptoms. Method: A total of 77 Veterans (mTBI = 43, MCs = 34) completed neuropsychological testing, diffusion tensor imaging (DTI), and PTSD symptom ratings. EF-IIV was calculated as the standard deviation across six tests of EF, along with an EF-Mean composite. DSI Studio connectometry analysis identified white matter tracts significantly associated with EF-IIV according to generalized fractional anisotropy (GFA). Results: After adjusting for EF-Mean and PTSD symptoms, the mTBI group showed significantly higher EF-IIV than MCs. Groups did not differ on EF-Mean after adjusting for PTSD symptoms. Across groups, PTSD symptoms significantly negatively correlated with EF-Mean, but not with EF-IIV. EF-IIV significantly negatively correlated with GFA in multiple white matter pathways connecting frontal and more posterior regions. Conclusions: Veterans with mTBI demonstrated significantly greater IIV across EF tests compared to MCs, even after adjusting for mean group differences on those measures as well as PTSD severity. Findings suggest that, in contrast to analyses that explore effects of mean performance across tests, discrepancy analyses may capture unique variance in neuropsychological performance and more sensitively capture cognitive disruption in Veterans with mTBI histories. Importantly, findings show that EF-IIV is negatively associated with the microstructure of white matter pathways interconnecting cortical regions that mediate executive function and attentional processes.
