Cerebral grey matter may not explain sleep slow-wave characteristics after severe brain injury.

Sleep slow waves are the hallmark of deeper non-rapid eye movement sleep. It is generally assumed that grey matter properties predict slow-wave density, morphology, and spectral power in healthy adults. Here, we tested the association between grey matter volume (GMV) and slow-wave characteristics in 27 moderate to severe traumatic brain injury patients (TBI; 32.0 ± 12.2 years old, eight women) compared to 32 healthy controls (29.2 ± 11.5 years old, nine women). Participants underwent overnight polysomnography and cerebral MRI with a 3-tesla scanner. A whole-brain voxel-wise analysis was performed to compare GMV between groups. Slow-wave density, morphology, and spectral power (0.4-6  Hz) were computed, and GMV was extracted from the thalamus, cingulate, insula, precuneus, and orbitofrontal cortex to test the relationship between slow waves and grey matter in regions implicated in the generation and/or propagation of slow waves. Compared to controls, TBI patients had significantly lower frontal and temporal GMV and exhibited a subtle decrease in slow-wave frequency. Moreover, higher GMV in the orbitofrontal cortex, insula, cingulate cortex, and precuneus was associated with higher slow-wave frequency and slope, only in healthy controls. Higher orbitofrontal GMV was also associated with higher slow-wave density in healthy participants. While we observed the expected associations between GMV and slow-wave characteristics in healthy controls, no such associations were observed in the TBI group despite lower GMV. This finding challenges the presumed role of GMV in slow-wave generation and morphology.Significance Statement Because sleep slow waves play a key role in cognition, synaptic plasticity, and restorative sleep, understanding how they relate to cerebral matter integrity is especially important in the context of brain atrophy following moderate to severe traumatic brain injury (TBI). We found that higher grey matter volume (GMV) in regions involved in slow-wave generation and propagation was associated with faster and steeper slow waves in healthy individuals. However, these associations were not observed in TBI participants, raising questions about the degree of contribution of GMV to slow-wave properties in patients with lower grey matter relative to controls. These findings challenge our current understanding of the link between grey matter integrity and slow waves, highlighting the complexity of this relationship.

Physicians' beliefs and perceived importance of traumatic brain injury-associated agitation in critically ill patients: a survey of Canadian intensivists.

PURPOSE: Agitation is a common behavioural problem following traumatic brain injury (TBI). Intensive care unit (ICU) physicians' perspectives regarding TBI-associated agitation are unknown. Our objective was to describe physicians' beliefs and perceived importance of TBI-associated agitation in critically ill patients. METHODS: Following current standard guidance, we built an electronic, self-administrated, 42-item survey, pretested it for reliability and validity, and distributed it to 219 physicians working in 18 ICU level-1 trauma centres in Canada. We report the results using descriptive statistics. RESULTS: The overall response rate was 93/219 (42%), and 76/93 (82%) respondents completed the full survey. Most respondents were men with ten or more years of experience. Respondents believed that pre-existing dementia (90%) and regular recreational drug use (86%) are risk factors for agitation. Concerning management, 91% believed that the use of physical restraints could worsen agitation, 90% believed that having family at the bedside reduces agitation, and 72% believed that alpha-2 adrenergic agonists are efficacious for managing TBI agitation. Variability was observed in beliefs on epidemiology, sex, gender, age, socioeconomic status, and other pharmacologic options. Respondents considered TBI agitation frequent enough to justify the implementation of management protocols (87%), perceived the current level of clinical evidence on TBI agitation management to be insufficient (84%), and expressed concerns about acute and long-term detrimental outcomes and burden to patients, health care professionals, and relatives (85%). CONCLUSION: Traumatic brain injury-associated agitation in critically ill patients was perceived as an important issue for most ICU physicians. Physicians agreed on multiple approaches to manage TBI-associated agitation although agreement on epidemiology and risk factors was variable.

RéSUMé: OBJECTIF: L'agitation est un problème de comportement courant à la suite d'un traumatisme crânien (TC). Le point de vue des médecins des unités de soins intensifs (USI) sur l'agitation associée aux traumatismes crâniens est inconnu. Notre objectif était de décrire les croyances et l'importance perçue par les médecins de l'agitation associée aux traumatismes crâniens chez les patient·es gravement malades. MéTHODE: Conformément aux lignes directrices standard actuelles, nous avons élaboré un sondage électronique auto-administré de 42 questions, l'avons testé au préalable pour en vérifier la fiabilité et la validité, et l'avons distribué à 219 médecins travaillant dans les USI de 18 centres de traumatologie de niveau 1 au Canada. Les résultats sont présentés à l'aide de statistiques descriptives. RéSULTATS: Le taux de réponse global a été de 93 sur 219 (42 %) et 76 sur 93 (82 %) personnes interrogées ont répondu à l'ensemble du sondage. La plupart des répondant·es étaient des hommes comptant dix ans ou plus d'expérience. Les répondant·es sont d'avis que la démence préexistante (90 %) et la consommation régulière de drogues à des fins récréatives (86 %) sont des facteurs de risque d'agitation. En ce qui concerne la prise en charge, 91 % des répondant·es estiment que l'utilisation de contentions physiques peut aggraver l'agitation, 90 % croient que le fait d'avoir de la famille au chevet du patient ou de la patiente réduit l'agitation et 72 % pensent que les agonistes alpha-2 adrénergiques sont efficaces pour gérer l'agitation causée par les traumatismes crâniens. Une variabilité a été observée dans les croyances concernant l'épidémiologie, le sexe, le genre, l'âge, le statut socio-économique et d'autres options pharmacologiques. Les répondant·es considéraient que l'agitation liée aux traumatismes crâniens était suffisamment fréquente pour justifier la mise en œuvre de protocoles de prise en charge (87 %), estimaient que le niveau actuel de données probantes cliniques sur la prise en charge de l'agitation causée par un traumatisme crânien était insuffisant (84 %), et se sont dit·es préoccupé·es par les conséquences préjudiciables aiguës et à long terme et par le fardeau pour les patient·es, les professionnel·les de la santé et les proches (85 %). CONCLUSION: L'agitation associée à un traumatisme crânien chez les patient·es gravement malades était perçue comme un problème important pour la plupart des médecins des soins intensifs. Les médecins s'entendaient sur plusieurs approches pour gérer l'agitation associée aux traumatismes crâniens, bien que l'accord sur l'épidémiologie et les facteurs de risque était variable.

Non-pharmacological interventions for sleep disruptions and fatigue after traumatic brain injury: a scoping review.

OBJECTIVE: The aim of this study was to conduct a scoping review to determine the nature, variety, and volume of empirical evidence on nonpharmacological interventions for sleep disturbances with potential implications for fatigue in adults sustaining a traumatic brain injury (TBI). METHODS: A systematic literature search was conducted across four databases to identify primary studies testing a single non-pharmacological intervention or a combination of non-pharmacological interventions for sleep disturbances and fatigue in community-dwelling adults with TBI. RESULTS: Sixteen studies were reviewed addressing six non-pharmacological interventions for sleep disruptions and fatigue after TBI including light therapy, cognitive-behavioral therapy, warm footbath application, shiatsu, and sleep hygiene protocol. Non-pharmacological interventions involving light or cognitive-behavioral therapy were reported in 75% of the studies. Actigraphy-based estimation of total sleep time and subjective level of fatigue were frequent outcomes. CONCLUSION: While this scoping review has utility in describing existing non-pharmacological approaches to manage sleep and fatigue after TBI, the findings suggest that interventions are often developed without considering TBI individuals' source of motivation and the need for support in self-administration. Future studies may achieve greater sustainability by considering the evolving needs of TBI patients and their families and the drivers and barriers that might influence non-pharmacological intervention use at home.

Use of actigraphy for monitoring agitation and rest-activity cycles in patients with acute traumatic brain injury in the ICU.

BACKGROUND: In traumatic brain injury patients (TBI) admitted to the intensive care unit (ICU), agitation can lead to accidental removal of catheters, devices as well as self-extubation and falls. Actigraphy could be a potential tool to continuously monitor agitation. The objectives of this study were to assess the feasibility of monitoring agitation with actigraphs and to compare activity levels in agitated and non-agitated critically ill TBI patients. METHODS: Actigraphs were placed on patients' wrists; 24-hour monitoring was continued until ICU discharge or limitation of therapeutic efforts. Feasibility was assessed by actigraphy recording duration and missing activity count per day. RESULTS: Data from 25 patients were analyzed. The mean number of completed day of actigraphy per patient was 6.5 ± 5.1. The mean missing activity count was 20.3 minutes (±81.7) per day. The mean level of activity measured by raw actigraphy counts per minute over 24 hours was higher in participants with agitation than without agitation. CONCLUSIONS: This study supports the feasibility of actigraphy use in TBI patients in the ICU. In the acute phase of TBI, agitated patients have higher levels of activity, confirming the potential of actigraphy to monitor agitation.

A dimensional analysis of experienced intensive care unit nurses' clinical decision-making for bleeding after cardiac surgery.

BACKGROUND: Bleeding following cardiac surgery is common and serious, yet a gap persists in understanding how experienced intensive care nurses identify and respond to such complications. AIM: To describe the clinical decision-making of experienced intensive care unit nurses in addressing bleeding after cardiac surgery. STUDY DESIGN: This qualitative study adopted the Recognition-Primed Decision Model as its theoretical framework. Thirty-nine experienced nurses from four adult intensive care units participated in semi-structured interviews based on the critical decision method. The interviews explored their clinical judgements and decisions in bleeding situations, and data were analysed through dimensional analysis, an alternative to grounded theory. RESULTS: Participants maintained consistent vigilance towards post-cardiac surgery bleeding, recognizing it through a haemorrhagic dimension associated with blood loss and chest drainage and a hypovolemic dimension focusing on the repercussions of reduced blood volume. These dimensions organized their understanding of bleeding types (i.e., normal, medical, surgical, tamponade) and necessary actions. Their decision-making encompassed monitoring bleeding, identifying the cause, stopping the bleeding, stabilizing haemodynamic and supporting the patient and family. Participants also adapted their actions to specific circumstances, including local practices, professional autonomy, interprofessional dynamics and resource availability. CONCLUSIONS: Nurses' decision-making was shaped by their personal attributes, the patient's condition and contextual circumstances, underscoring their expertise and pivotal role in anticipating actions and adapting to diverse conditions. The concept of actionability emerged as the central dimension explaining their decision-making, defined as the capability to implement actions towards specific goals within the possibilities and constraints of a situation. RELEVANCE TO CLINICAL PRACTICE: This study underscores the need for continual updates to care protocols to align with current evidence and for quality improvement initiatives to close existing practice gaps. Exploring the concept of actionability further, developing adaptability-focused educational programmes, and understanding decision-making intricacies are crucial for informing nursing education and decision-support systems.

Beyond the obstacles : diving into the heart of interventions promoting the involvement of relatives in intensive care unit / Au-delà des obstacles : plonger au cœur des interventions favorisant l'implication des proches aux soins intensifs.

Background: Involving family caregivers in direct care in the intensive care unit is increasingly recognized as part of best care practices. However, little is known about the factors that foster this involvement. Objective: The aim of this study was to identify the factors in the literature that promote or limit the involvement of family caregivers in direct care in adult intensive care units. Method: A rapid literature review was conducted in MEDLINE and CINAHL for English-and French-language articles published between 2010 and 2021. Results: 25 articles were selected (n=20 primary studies, n=5 literature syntheses). The results show a diversity of factors that influence the involvement of relatives in direct intensive care units. These factors can be grouped into four categories : relational, informal, clinical, and political. Conclusion: This review identifies the organizational, clinical and human issues relating to the involvement of family caregivers in direct care in order to propose recommendations to facilitate the implementation of this approach in the intensive care units.

Contexte: L'implication des proches aidants dans les soins directs à l'unité des soins intensifs est de plus en plus reconnue comme faisant partie des meilleures pratiques de soins. Toutefois, les facteurs permettant de favoriser cet engagement sont peu connus. Objectifs: Cette étude vise à identifier dans la littérature les facteurs favorables ou limitant l'implication des proches aidants dans les soins directs dans les unités des soins intensifs adultes, et à proposer des recommandations pour favoriser cette implication. Méthode: Une revue rapide des écrits a été réalisée dans MEDLINE et CINAHL afin d'étudier les articles publiés entre 2010 et 2021 en français ou en anglais. Résultats: Au total, 25 articles ont été retenus (n = 20 études primaires, n = 5 synthèses des connaissances). Conclusion: Cette revue permet d'identifier les enjeux organisationnels, cliniques et humains relatifs à l'implication des PA dans les soins directs afin de proposer des recommandations pour faciliter l'implantation de cette approche dans les unités des soins intensifs.

Brain Responses to Propofol in Advance of Recovery from Coma and Disorders of Consciousness: A Preliminary Study.

Rationale: Predicting recovery of consciousness in unresponsive, brain-injured individuals has crucial implications for clinical decision-making. Propofol induces distinctive brain network reconfiguration in the healthy brain as it loses consciousness. In patients with disorders of consciousness, the brain network's reconfiguration to propofol may reveal the patient's underlying capacity for consciousness. Objectives: To design and test a new metric for the prognostication of consciousness recovery in disorders of consciousness. Methods: Using a within-subject design, we conducted an anesthetic protocol with concomitant high-density EEG in 12 patients with a disorder of consciousness after a brain injury. We quantified the reconfiguration of EEG network hubs and directed functional connectivity before, during, and after propofol exposure and obtained an index of propofol-induced network reconfiguration: the adaptive reconfiguration index. We compared the index of patients who recovered consciousness 3 months after EEG (n = 3) to that of patients who did not recover or remained in a chronic disorder of consciousness (n = 7) and conducted a logistic regression to assess prognostic accuracy. Measurements and Main Results: The adaptive reconfiguration index was significantly higher in patients who later recovered full consciousness (U value = 21, P = 0.008) and able to discriminate with 100% accuracy whether the patient recovered consciousness. Conclusions: The adaptive reconfiguration index of patients who recovered from a disorder of consciousness at 3-month follow-up was linearly separable from that of patients who did not recover or remained in a chronic disorder of consciousness on the single-subject level. EEG and propofol can be administered at the bedside with few contraindications, affording the adaptive reconfiguration index tremendous translational potential as a prognostic measure of consciousness recovery in acute clinical settings.

Sleep Disruptions in Hospitalized Adults Sustaining a Traumatic Brain Injury: A Scoping Review.

OBJECTIVE: Adults sustaining a traumatic brain injury (TBI) are at risk of sleep disturbances during their recovery, including when such an injury requires hospitalization. However, the sleep-wake profile, and internal and external factors that may interfere with sleep initiation/maintenance in hospitalized TBI patients are poorly understood. This review aimed to: (1) identify/summarize the existing evidence regarding sleep and sleep measurements in TBI adults receiving around-the-clock care in a hospital or during inpatient rehabilitation, and (2) identify internal/external factors linked to poor sleep in this context. METHODS: A scoping review was conducted in accordance with the PRISMA Scoping Review Extension guidelines. A search was conducted in MEDLINE, PsycINFO, CINAHL, and Web of Science databases. RESULTS: Thirty relevant studies were identified. The most common sleep variables that were put forth in the studies to characterize sleep during hospitalization were nighttime sleep time (mean = 6.5 hours; range: 5.2-8.9 hours), wake after sleep onset (87.1 minutes; range: 30.4-180 minutes), and sleep efficiency (mean = 72.9%; range: 33%-96%) using mainly actigraphy, polysomnography, and questionnaires (eg, the sleep-wake disturbance item of the Delirium Rating Scale or the Pittsburgh Sleep Quality Index). Twenty-four studies (80%) suggested that hospitalized TBI patients do not get sufficient nighttime sleep, based on the general recommendations for adults (7-9 hours per night). Sleep disruptions during hospitalization were found to be associated to several internal factors including TBI severity, cognitive status, and analgesia intake. External and modifiable factors, such as noise, light, and patient care, were consistently associated with sleep disruptions in this context. CONCLUSION: Although the literature on sleep disturbances in hospitalized TBI patients has been increasing in recent years, many gaps in knowledge remain, including phenotypes and risk factors. Identifying these factors could help clinicians better understand the multiple sources of TBI patients' sleep difficulties and intervene accordingly.

Development, evaluation and adaptation of a critical realism informed theory of procedural pain management in preterm infants: The PAIN-Neo theory.

AIM: To present the development, evaluation and adaptation of the PAIN-Neo theory. DESIGN: Theory development. DATA SOURCES: A review of literature was conduct from 1980 to 2021. RESULTS: Using a critical realism paradigm, this paper presents the PAIN-Neo theory, which was developed from an analysis of existing theoretical perspectives on paediatric procedural pain, empirical studies conducted with preterm infants, and the research team's pain management expertise. The theory was then empirically tested and fine-tuned. IMPLICATIONS FOR NURSING: The PAIN-Neo theory highlights that the neonatal nurse is part of a larger picture as she is influenced by factors related to her unit, hospital and country of practice. This theory emphasizes the importance of parental involvement in pain management, which is consistent with family-centred nursing practices. CONCLUSION: The PAIN-Neo theory reflects the complexity of pain management nursing. This theory is innovative and specific enough to guide practice, structure research projects and contribute to the body of knowledge in the discipline of nursing.

Feasibility and acceptability of hypnosis-derived communication administered by trained nurses to improve patient well-being during outpatient chemotherapy: a pilot-controlled trial.

PURPOSE: This pilot-controlled trial aimed to examine the feasibility and acceptability of hypnosis-derived communication (HC) administered by trained nurses during outpatient chemotherapy to optimize symptom management and emotional support - two important aspects of patient well-being in oncology. METHODS: The trial was conducted in two outpatient oncology units: (1) intervention site (usual care with HC), and (2) control site (usual care). Nurses at the intervention site were invited to take part in an 8-h training in HC. Participants' self-ratings of symptoms and emotional support were gathered at predetermined time points during three consecutive outpatient visits using the Edmonton Symptom Assessment Scale and the Emotional Support Scale. RESULTS: Forty-nine patients (24 in the intervention group, 25 in the control group) with different cancer types/stages were recruited over a period of 3 weeks and completed the study. All nurses (N = 10) at the intervention site volunteered to complete the training and were able to include HC into their chemotherapy protocols (about ± 5 min/intervention). Compared to usual care, patients exposed to HC showed a significant reduction in physical symptoms during chemotherapy. In contrast, perception of emotional support did not show any significant effect of the intervention. Participants exposed to HC report that the intervention helped them relax and connect on a more personal level with the nurse during chemotherapy infusion. CONCLUSIONS: Our results suggest that HC is feasible, acceptable, and beneficial for symptom management during outpatient chemotherapy. While future studies are needed, hypnosis techniques could facilitate meaningful contacts between cancer patients and clinicians in oncology. TRIAL REGISTRATION: Clinical Trial Identifier: NCT04173195, first posted on November 19, 2019.

Nurses' perception of integrating an innovative clinical hypnosis-derived intervention into outpatient chemotherapy treatments.

Introduction: Conversational hypnosis (CH) is known to optimize the management of symptoms resulting from antineoplastic treatment. However, the perception of nurses who have been called upon to integrate this practice into their care has yet to be documented. Goal: Describe how nurses perceive the integration of CH into chemotherapy-related care. Methods: Individual interviews and an iterative analysis were conducted with six nurses who had previous experience in CH in an outpatient oncology clinic. Findings: Six themes emerged: 1) the outpatient oncology clinic, a saturated care setting; 2) the key elements supporting the integration of CH into care; 3) an added value for patients; 4) a positive and rewarding experience for nurses; 5) collateral benefits; and 6) CH, an approach that warrants consideration amid the pandemic. Conclusion: These findings shed light on nurses' unique point of view regarding the challenges and benefits of integrating CH into oncology care.

Brain white matter damage and its association with neuronal synchrony during sleep.

The restorative function of sleep partly relies on its ability to deeply synchronize cerebral networks to create large slow oscillations observable with EEG. However, whether a brain can properly synchronize and produce a restorative sleep when it undergoes massive and widespread white matter damage is unknown. Here, we answer this question by testing 23 patients with various levels of white matter damage secondary to moderate to severe traumatic brain injuries (ages 18-56; 17 males, six females, 11-39 months post-injury) and compared them to 27 healthy subjects of similar age and sex. We used MRI and diffusion tensor imaging metrics (e.g. fractional anisotropy as well as mean, axial and radial diffusivities) to characterize voxel-wise white matter damage. We measured the following slow wave characteristics for all slow waves detected in N2 and N3 sleep stages: peak-to-peak amplitude, negative-to-positive slope, negative and positive phase durations, oscillation frequency, and slow wave density. Correlation analyses were performed in traumatic brain injury and control participants separately, with age as a covariate. Contrary to our hypotheses, we found that greater white matter damage mainly over the frontal and temporal brain regions was strongly correlated with a pattern of higher neuronal synchrony characterized by slow waves of larger amplitudes and steeper negative-to-positive slopes during non-rapid eye movement sleep. The same pattern of associations with white matter damage was also observed with markers of high homeostatic sleep pressure. More specifically, higher white matter damage was associated with higher slow-wave activity power, as well as with more severe complaints of cognitive fatigue. These associations between white matter damage and sleep were found only in our traumatic brain injured participants, with no such correlation in controls. Our results suggest that, contrary to previous observations in healthy controls, white matter damage does not prevent the expected high cerebral synchrony during sleep. Moreover, our observations challenge the current line of hypotheses that white matter microstructure deterioration reduces cerebral synchrony during sleep. Our results showed that the relationship between white matter and the brain's ability to synchronize during sleep is neither linear nor simple.

Does age matter? A mixed methods study examining determinants of good recovery and resilience in young and middle-aged adults following moderate-to-severe traumatic brain injury.

AIM: To examine whether age contributes to functional recovery and resilience after moderate-to-severe traumatic brain injury. BACKGROUND: The ability to recover may change across the lifespan, but the influence of age on brain injury outcome is understudied. DESIGN: Mixed methods study. METHODS: All adults of working age (18-64 years) discharged from a level I trauma centre between 2010-2013 after sustaining a moderate-to-severe traumatic brain injury were considered. Functional recovery was assessed during a telephone interview with the Glasgow Outcome Scale-Extended 12-36 months postinjury. A subgroup completed the Connor-Davidson Resilience Scale and a face-to-face interview about resilience. RESULTS: Ninety-seven young (mean age: 27 years; 75% male) and 47 middle-aged brain trauma survivors (mean age: 53 years; 75% male) completed the telephone interview. Eight young and five middle-aged adults were also assessed for resilience. Overall, young participants experienced more severe head injuries. Yet, they achieved slightly higher levels of functional recovery compared with middle-aged ones as per the Glasgow Outcome Scale-Extended. Controlling for CT scan findings and posttraumatic amnesia duration, age was not found to be associated to functional recovery in adults of working age. Although both groups showed similar levels of resilience, young participants discussed the challenges related to "having more time on their hands" and "being a changed person", two elements perceived positively by middle-aged ones. CONCLUSION: While age does not appear to interfere with functional recovery in adults of working age, younger brain trauma survivors could benefit from nursing interventions to strengthen their resilience process related to re-employment orientation and identity.

Visual Fixation in the ICU: A Strong Predictor of Long-Term Recovery After Moderate-to-Severe Traumatic Brain Injury.

OBJECTIVE: Posttraumatic amnesia is superior to the initial Glasgow Coma Scale score for predicting traumatic brain injury recovery, but it takes days/weeks to assess. Here, we examined whether return of visual fixation-a potential marker of higher cognitive function-within 24 hours of ICU admission could be used as an early predictor of traumatic brain injury recovery. DESIGN: Two-phase cohort study. SETTING: Level-I trauma ICU. PATIENTS: Moderate-to-severe traumatic brain injury discharged alive between 2010 and 2013. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Return of visual fixation was assessed through standard behavioral assessments in 181 traumatic brain injury patients who had lost the ability to fixate at ICU admission (phase 1) and compared with posttraumatic amnesia duration and the initial Glasgow Coma Scale score to predict performance on the Glasgow Outcome Scale-Extended 10-40 months after injury (n = 144; phase 2a). A subgroup also completed a visual attention task (n = 35; phase 2b) and a brain MRI after traumatic brain injury (n = 23; phase 2c). With an area under the curve equal to 0.85, presence/absence of visual fixation at 24 hours of ICU admission was found as performant as posttraumatic amnesia (area under the curve, 0.81; difference between area under the curve, 0.04; p = 0.28) for predicting patients' Glasgow Outcome Scale-Extended score. Conversely, the initial Glasgow Coma Scale score was not (area under the curve, 0.63). Even when controlling for age/medication/CT scan findings, fixation remained a significant predictor of Glasgow Outcome Scale-Extended scores (ß, -0.29; p < 0.05). Poorer attention performances and greater regional brain volume deficits were also observed in patients who could not fixate at 24 hours of ICU admission versus those who could. CONCLUSIONS: Visual fixation within 24 hours of ICU admission could be as performant as posttraumatic amnesia for predicting traumatic brain injury recovery, introducing a new variable of interest in traumatic brain injury outcome research.

Evaluation of the preliminary effectiveness of hand massage therapy on postoperative pain of adults in the intensive care unit after cardiac surgery: a pilot randomized controlled trial.

Although many intensive care unit patients experience significant pain, very few studies explored massage to maximize their pain relief. This study aimed to evaluate the preliminary effects of hand massage on pain after cardiac surgery in the adult intensive care unit. A pilot randomized controlled trial was used for this study. The study was conducted in a Canadian medical-surgical intensive care unit. Forty adults who were admitted to the intensive care unit after undergoing elective cardiac surgery in the previous 24 hours participated in the study. They were randomly assigned to the experimental (n = 21) or control (n = 19) group. The experimental group received a 15-minute hand massage, and the control group received a 15-minute hand-holding without massage. In both groups the intervention was followed by a 30-minute rest period. The interventions were offered on 2-3 occasions within 24 hours after surgery. Pain, muscle tension, and vital signs were assessed. Pain intensity and behavioral scores were decreased for the experimental group. Although hand massage decreased muscle tension, fluctuations in vital signs were not significant. This study supports potential benefits of hand massage for intensive care unit postoperative pain management. Although larger randomized controlled trials are necessary, this low-cost nonpharmacologic intervention can be safely administered.

Behavioral and physiologic indicators of pain in nonverbal patients with a traumatic brain injury: an integrative review.

The use of behavioral and physiologic indicators is recommended for pain assessment in nonverbal patients. Traumatic brain injuries (TBI) can lead to neurologic changes and affect the way patients respond to pain. As such, commonly used indicators of pain may not apply to TBI patients. This study aimed to review the literature about behavioral/physiologic indicators of pain in nonverbal TBI patients. An integrative review method was used. Medline (from 1948 to June 2011), Cinahl, and Cochrane databases were searched using any combination of the terms brain injury, behavioral indicators, behavioral scale, physiologic indicators, pain, pain assessment, and pain measurement. All articles reporting expert opinion or original data about the validity of behavioral and/or physiologic indicators of pain in TBI patients were considered. For each article included, the quality of findings/clinical recommendations was graded independently by two raters using SORT taxonomy. Eight papers were reviewed. Overall, TBI patients seemed to present a wider range of behavioral reactions to pain than other adult populations. In addition to the commonly observed grimace, agitation, and increased muscle tension, 14%-72% of TBI patients showed raising eyebrows, opening eyes, weeping eyes, and absence of muscle tension when exposed to pain. Those atypical reactions appeared to be present only in the acute phase of TBIs recovery. Similarly to other populations, vital signs were identified as potential indicators of pain in TBI patients. Further research studying TBI patients and considering changes in level of consciousness, location/severity of brain injury, and administration of analgesic/sedative is needed. Until then, nurses should follow the current clinical recommendations.

Do All Patients Benefit From the Soothing Properties of a Conversational Nursing Intervention to Reduce Symptom Burden During Outpatient Chemotherapy?: A Multimethod Secondary Analysis.

BACKGROUND: Soothing conversation (SC) is particularly promising for symptom management during outpatient chemotherapy. However, we know little about the profile of patients who are most likely to benefit from this intervention. OBJECTIVE: To gain a better understanding of the profile of patients most likely to benefit from SC to reduce symptom burden during outpatient chemotherapy. METHODS: We performed a multimethod secondary analysis of 2 data sets: the first gathered during a quantitative pilot trial investigating the impact of SC on patients' symptom fluctuations during chemotherapy perfusion (n = 24); the second derived from qualitative interviews about nurses' experiences with SC in this context (n = 6). RESULTS: Secondary quantitative analysis suggests that symptom control with SC is more effective in older patients, reporting lower education, widowed status, work incapacity, advanced cancer, and undergoing chemotherapy perfusion for less than 1 hour. According to nurses' interviews, SC could best benefit patients (1) prone to anxiety and fear, (2) with unalleviated pain, (3) who are unaccompanied during treatment, and contrary to what was shown with quantitative data, (4) undergoing longer perfusion duration. CONCLUSION: Although this study provides valuable insights, much work remains to be done to fully understand the factors that predispose patients to respond positively to SC during outpatient chemotherapy. IMPLICATIONS FOR PRACTICE: This study extends previous research on the effectiveness of SC for symptom management during outpatient chemotherapy by comparing nurses' experience with the intervention to patients' results. Results could be used to inform the assignment and delivery of supportive communication-based interventions during chemotherapy protocols.
