Daily life without cranial bone protection while awaiting cranioplasty: a qualitative study.

PURPOSE: Decompressive craniectomy is occasionally performed as a life-saving neurosurgical intervention in patients with acute severe brain injury to reduce refractory intracranial hypertension. Subsequently, cranioplasty (CP) is performed to repair the skull defect. In the meantime, patients are living without cranial bone protection, and little is known about their daily life. This study accordingly explored daily life among patients living without cranial bone protection after decompressive craniectomy while awaiting CP. METHODS: A multiple-case study examined six purposively sampled patients, patients' family members, and healthcare staff. The participants were interviewed and the data were analyzed using qualitative content analysis. RESULTS: The cross-case analysis identified five categories: "Adapting to new ways of living," "Constant awareness of the absence of cranial bone protection," "Managing daily life requires available staff with adequate qualifications," "Impact of daily life depends on the degree of recovery," and "Daily life stuck in limbo while awaiting cranioplasty." The patients living without cranial bone protection coped with daily life by developing new habits and routines, but the absence of cranial bone protection also entailed inconveniences and limitations, particularly among the patients with greater independence in their everyday living. Time spent awaiting CP was experienced as being in limbo, and uncertainty regarding planning was perceived as frustrating. CONCLUSION: The results indicate a vulnerable group of patients with brain damage and communication impairments struggling to find new routines during a waiting period experienced as being in limbo. Making this period safe and reducing some problems in daily life for those living without cranial bone protection calls for a person-centered approach to care involving providing contact information for the correct healthcare institution and individually planned scheduling for CP.

Is this to be another project that fizzles out? Using the i-PARIHS framework to evaluate implementation of a mentoring programme.

It is well-known that the implementation of evidence into clinical practice is complex and challenging. The integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework conceptualizes successful implementation of evidence into practice. As the implementation of the mentoring programme proved to be a challenge, it seemed valuable to retrospectively study the implementation process using a framework like the i-PARIHS. AIM: The aim of this study was to evaluate implementation of a multifaceted mentoring programme for bedside nurses using the i-PARIHS framework, to identify factors that influenced the implementation. DESIGN: A secondary analysis of qualitative data using the i-PARIHS framework as the theoretical lens. METHOD: A directed content analysis was performed, driven theoretically by the i-PARIHS framework. The analysis focused separately on (a) characteristics of the innovation and (b) successful and hindering factors in the implementation process. RESULTS: The results showed that successful factors influencing implementation of the mentoring programme included supportive and actively involved formal leaders and supervisors at the unit level. A major hindering factor was lack of resources in the form of personnel, time and money. A lack of facilitators, particularly experienced facilitators, throughout the organization hindered implementation. The i-PARIHS framework offered a structured how-to guide to identify factors that influenced the implementation process. CONCLUSION: Implementation of the mentoring programme was a challenge for the organization. Investment into implementation should continue, with a more structured facilitation process. A structured and prioritized management system, including supportive leadership at the unit level, should be established by the hospital board. IMPLICATIONS FOR THE PROFESSION: There is a need for experienced facilitators throughout the organization. This is crucial to achieve sustainability in the mentoring programme and ensure that the large investments of staff resources and money do not fizzle out. IMPACT: What problem did the study address? Implementing a mentoring programme for nurses in a large university hospital proved to be a challenge. Therefore, it seemed valuable to retrospectively study the implementation process using a framework like the i-PARIHS. What were the main findings? A lack of facilitators, particularly experienced facilitators, throughout the organization hindered the implementation. The i-PARIHS framework offered a structured how-to guide to identify factors that influenced the implementation process. Where and on whom will the research have an impact? Our findings are important for leaders on all levels in a hospital setting, including the hospital board, heads of departments and nurse managers. REPORTING METHOD: Consolidated criteria for reporting qualitative research (COREQ): a 32-item checklist for interviews and focus groups is used. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contribution.

Missed nursing care in surgical care- a hazard to patient safety: a quantitative study within the inCHARGE programme.

BACKGROUND: Missed nursing care occurs globally, and the consequences are severe for the patients when fundamental care needs are not fulfilled, nor delivered in a person-centred way. This study aimed to investigate the occurrence and cause of missed nursing care, and the relationship between registered nurses' and nursing assistants' perceptions of missed nursing care, in a surgical care context. METHODS: A quantitative study was performed using the MISSCARE survey, measuring missed nursing care and associated reasons, in three surgical wards with registered nurses and nursing assistants as the participants (n = 118), during May-November in 2022. The MISSCARE survey also covers background data such as job satisfaction and intention to leave. The survey was distributed paper-based and the response rate was 88%. RESULTS: Aspects of nursing care rated to be missed the most were 'attending interdisciplinary care conferences', 'turning patient every 2 h', 'ambulation 3 times per day or as ordered', and 'mouth care'. Differences between registered nurse and nursing assistant ratings were detected for eight out of 24 items, where registered nurses rated more missed nursing care. The uppermost reasons for missed nursing care were 'inadequate number of staff' and 'unexpected rise in patient volume and/or acuity on the unit'. Registered nurses and nursing assistants rated differently regarding six of 17 items. Almost every fourth staff member (24.6%, n = 29) had the intention to leave within a year in the present department. CONCLUSIONS: The occurrence of missed nursing care is frequent in the surgical context, and in combination with a high number of staff members intending to leave their employment, poses a hazard to patient safety. Registered nurses, holding higher educational levels, reported more missed care compared with the nursing assistants. The main reason for missed nursing care was an inadequate number of staff. These findings support a warranted investment in nursing within the organisation. The results can be used to form strategies and interventions, to reduce nurse attrition and optimise competence utilisation, and to achieve safe person-centered fundamental care.

Effective learning activity to facilitate post-graduate nursing students' utilization of nursing theories - Using the fundamentals of care framework.

AIMS: To explore how postgraduate nursing students used the Fundamentals of Care framework in a written assignment based on a clinical situation, and describe their learning process in using the framework. DESIGN: A qualitative descriptive study design applying the Fundamentals of Care framework. METHODS: Postgraduate nursing students' theoretical written assignments (n = 35) based on self-experienced clinical cases were included. The data were collected in 2021 in five specialties in a postgraduate nursing programme in Sweden. The data were analysed using content analysis. RESULTS: Applying the framework to a self-experienced clinical case illuminated the importance of nurse-patient relationships and clarified the meaning of person-centred care. The students assessed the framework as easy-to-use bedside as a guide to providing nursing care. By using the framework, the students were aided in reasoning about the fundamental values of care such as ethics, equality in healthcare and patient rights. When students reflected on their learning process, they stated that the assignment taught them how to use the framework, as well as paving the way for finding and applying other theories of nursing. CONCLUSION: Learning activities with an opportunity to practice analysing nursing care guided by a theory, combined with a self-evaluating element, are conducive to deepening students' learning and improving their ability to use theories in clinical practice. IMPACT: The framework illuminated the importance of the nurse-patient relationship in nursing care to the students and made them recognize and value the clinical use of theories. It is the responsibility of leaders in nurse education and healthcare to provide the next generation of specialist nurses-future nursing leaders-with regular opportunities to analyse nursing care through theories and frameworks. Nurses call for continuous learning on theories; leaders in nurse education and healthcare must meet these needs.

Capturing of intracranial pressure treatment during neurointensive care in patients with acute brain injury using a novel tablet-based method.

Critical care is complex and stressful. It is difficult to register in real time data not recorded by automatic systems. Time-specific knowledge of manual measures is important for understanding pathophysiology and for analyzing treatment and quality of care. Therefore, a novel iPad-based method for registration of manual measures was developed, which many can build themselves. Using a configuration for intracranial pressure (ICP) management, the methodology was validated, ICP treatment captured, and the quality of ICP management evaluated. Twenty-two patients with acute brain injuries were studied. The iPad-system was totally used for 2538 h. Thirteen-hundred-five manual measures were entered. Thirty-nine episodes of predefined ICP insults were identified. During 16/39 episodes, ICP treatments were registered. For 4/39 episodes treatments were registered within 90 s before or after the episode. For 3/39 episodes it was registered that treatment was intentionally refrained. In 15/16 episodes without registered treatment, the insult was mild or reasonable explanations were found when medical records and the Patient data management system were reviewed. In one situation without particular circumstances, morphine and clonidine were given to decrease ICP but not registered. No episodes of downtime or loss of data occurred. The developed methodology appears to be stable and robust as well as feasible and user-friendly. It was possible to capture the treatment of ICP insults with high temporal resolution, and to evaluate the quality of ICP management. An own developed novel tablet-based system like our system may be a promising potential tool useful in various future intensive care applications.

Clinical outcome and prognostic factors in elderly traumatic brain injury patients receiving neurointensive care.

BACKGROUND: The probability of favorable outcome after traumatic brain injury (TBI) decreases with age. Elderly, ≥ 60 years, are an increasing part of our population. Recent studies have shown an increase of favorable outcome in elderly over time. However, the optimal patient selection and neurointensive care (NIC) treatments may differ in the elderly and the young. The aims of this study were to examine outcome in a larger group of elderly TBI patients receiving NIC and to identify demographic and treatment related prognostic factors. METHODS: Patients with TBI ≥ 60 years receiving NIC at our department between 2008 and 2014 were included. Demographics, co-morbidity, admission characteristics, and type of treatments were collected. Clinical outcome at around 6 months was assessed. Potential prognostic factors were included in univariate and multivariate regression analysis with favorable outcome as dependent variable. RESULTS: Two hundred twenty patients with mean age 70 years (median 69; range 60-87) were studied. Overall, favorable outcome was 46% (Extended Glasgow Outcome Scale (GOSE) 5-8), unfavorable outcome 27% (GOSE 2-4), and mortality 27% (GOSE 1). Significant independent negative prognostic variables were high age (p < 0.05), multiple injuries (p < 0.05), GCS M ≤ 3 on admission (p < 0.05), and mechanical ventilation (p < 0.001). CONCLUSIONS: Overall, the elderly TBI patients > 60 years receiving modern NIC in this study had a fair chance of favorable outcome without large risks for severe deficits and vegetative state, also in patients over 75 years of age. High age, multiple injuries, GCS M ≤ 3 on admission, and mechanical ventilation proved to be independent negative prognostic factors. The results underline that a selected group of elderly with TBI should have access to NIC.

How Anesthesiologists and Nurse Anesthetists Assess and Handle Patients' Perioperative Worries Without a Validated Instrument.

PURPOSE: To study how nurse anesthetists and anesthesiologists assess and handle patients' perioperative anxiety without using a validated instrument. DESIGN: Qualitative study. METHODS: Individual in-depth face-to-face interviews were conducted with nurse anesthetists (n = 9) and anesthesiologists (n = 5) from a university hospital in Sweden. Data were analyzed with thematic analysis according to Braun and Clark. FINDINGS: Two themes were identified: (1) I ask about anxiety, look for visual signs, and observe communication and (2) I handle patients' anxieties individually. In addition to subthemes describing assessment and handling of adults, it appeared that parents played an important role in children's perioperative anxiety. CONCLUSIONS: When not using a validated instrument, assessing perioperative anxiety is commonly based on the anesthesiologist's and nurse anesthetist's experience, knowledge, views, and attitudes. The evaluator's capability of using different strategies in the assessment and handling of perioperative anxiety is important.

Decompressive craniectomy in traumatic brain injury: usage and clinical outcome in a single centre.

BACKGROUND: Two randomised controlled trials (RCTs) of decompressive craniectomy (DC) in traumatic brain injury (TBI) have shown poor outcome, but there are considerations of how these protocols relate to real practice. The aims of this study were to evaluate usage and outcome of DC and thiopental in a single centre. METHOD: The study included all TBI patients treated at the neurointensive care unit, Akademiska sjukhuset, Uppsala, Sweden, between 2008 and 2014. Of 609 patients aged 16 years or older, 35 treated with DC and 23 treated with thiopental only were studied in particular. Background variables, intracranial pressure (ICP) measures and global outcome were analysed. RESULTS: Of 35 DC patients, 9 were treated stepwise with thiopental before DC, 9 were treated stepwise with no thiopental before DC and 17 were treated primarily with DC. Six patients received thiopental after DC. For 23 patients, no DC was needed after thiopental. Eighty-eight percent of our DC patients would have qualified for the DECRA study and 38% for the Rescue-ICP trial. Favourable outcome was 44% in patients treated with thiopental before DC, 56% in patients treated with DC without prior thiopental, 29% in patients treated primarily with DC and 52% in patients treated with thiopental with no DC. CONCLUSIONS: The place for DC in TBI management must be evaluated better, and we believe it is important that future RCTs should have clearer and less permissive ICP criteria regarding when thiopental should be followed by DC and DC followed by thiopental.

Promising clinical outcome of elderly with TBI after modern neurointensive care.

BACKGROUND: The increasing number of elderly patients with traumatic brain injury (TBI) leads to specific neurointensive care (NIC) challenges. Therefore, elderly subjects with TBI need to be further studied. In this study we evaluated the demographics, management and outcome of elderly TBI patients receiving modern NIC. METHODS: Patients referred to our NIC unit between 2008 and 2010 were included. Patients were divided in two age groups, elderly (E) ≥65 years and younger (Y) 64-15 years. Parameters studied were the dominant finding on CT scans, neurological motor skills and consciousness, type of monitoring, neurosurgical procedures/treatments and Glasgow Outcome Scale Extended score at 6 months after injury. RESULTS: Sixty-two E (22 %) and 222 Y (78 %) patients were included. Falls were more common in E (81 %) and vehicle accidents were more common in Y patients (37 %). Acute subdural hematoma was significantly more common in E (50 % of cases) compared to Y patients (18 %). Intracranial pressure was monitored in 44 % of E and 57 % of Y patients. Evacuation of significant mass lesions was performed more common in the E group. The NIC mortality was similar in both groups (4-6 %). Favorable outcome was observed in 72 % of Y and 51 % of E patients. At the time of follow-up 25 % of E and 7 % of Y patients had died. CONCLUSIONS: The outcome of elderly patients with TBI was significantly worse than in younger patients, as expected. However, as much as 51 % of the elderly patients showed a favorable outcome after NIC. We believe that these results encourage modern NIC in elderly patients with TBI. We need to study how secondary brain injury mechanisms differ in the older patients and to identify specific outcome predictors for elderly patients with TBI.

Updated periodic evaluation of standardized neurointensive care shows that it is possible to maintain a high level of favorable outcome even with increasing mean age.

BACKGROUND: Periodic evaluation of neurointensive care (NIC) is important. There is a risk that quality of daily care declines and there may also be unrecognized changes in patient characteristics and management. The aim of this work was to investigate the characteristics and outcome for traumatic brain injury (TBI) patients in the period 2008-2009 in comparison with 1996-1997 and to some extent also with earlier periods. METHODS: TBI patients 16-79 years old admitted from 2008 to 2009 were selected for the study. Glasgow Coma Scale Motor score at admission (GCS M), radiology, surgery, and outcome (Glasgow Outcome Extended Scale) were collected from Uppsala Traumatic Brain Injury Register. RESULTS: The study included 148 patients (mean age, 45 years). Patients >60 years old increased from 16 % 1996-1997 to 30 % 2008-2009 (p < 0.01). The proportion of GCS M 4-6 were similar, 92 vs. 93 % (NS). In 1996-1997 patients, 73 % had diffuse injury (Marshall classification) compared to 77 % for the 2008-2009 period (NS). More patients underwent surgery during 2008-2009 (43 %) compared to 1996-1997 (32 %, p < 0.05). Good recovery increased and mortality decreased substantially from 1980-1981 to 1987-1988 and to 1996-1997, but then the results were unchanged in the 2008-2009 period, with 73 % favorable outcome and 11 % mortality. Mortality increased in GCS M 6-4, from 2.8 % in 1996-1997 to 10 % in 2008-2009 (p < 0.05); most of the patients that died had aggravating factors, e.g., high age, malignancy. CONCLUSIONS: A large-proportion favorable outcome was maintained despite that patients >60 years with poorer prognosis doubled, indicating that the quality of NIC has increased or at least is unchanged. More surgery may have contributed to maintaining the large proportion of favorable outcome. For future improvements, more knowledge about TBI management in the elderly is required.

Acute neurosurgery for traumatic brain injury by general surgeons in Swedish county hospitals: a regional study.

BACKGROUND: Traditionally acute life-saving evacuations of extracerebral haematomas are performed by general surgeons on vital indication in county hospitals in the Uppsala-Örebro health care region in Sweden, a region characterized by long distances and a sparsely distributed population. Recently, it was stated in the guidelines for prehospital care of traumatic brain injury from the Scandinavian Neurosurgical Society that acute neurosurgery should not be performed in smaller hospitals without neurosurgical expertise. The aim of this study was to investigate: how often does acute decompressive neurosurgery occur in county hospitals in the Uppsala-Örebro region today, what is the indication for surgery, and what is the clinical outcome? Finally, the goal was to evaluate whether the current practice in the Uppsala-Örebro region should be revised. METHOD: Patients referred to the neurointensive care unit at the Department of Neurosurgery in Uppsala after acute evacuation of intracranial haematomas in the county hospitals 2005-2010 were included in the study. Data was collected retrospectively from the medical records following a predefined protocol. The presence of vital indication, radiological and clinical results, and long-term outcome were evaluated. FINDINGS: A total of 49 patients (17 epidural haematomas and 32 acute subdural haematomas) were included in the study. The operation was judged to have been performed on vital indication in all cases. The postoperative CT scan was improved in 92% of the patients. The reaction level and pupillary reactions were significantly improved after surgery. Long-term outcomes showed 51% favourable outcome, 33% unfavourable outcome, and in 16% the outcome was unknown. CONCLUSIONS: Looking at the indication for acute neurosurgery, the postoperative clinical and radiological results, and the long-term outcome, it appears that our regional policy regarding life-saving decompressive neurosurgery in county hospitals by general surgeons should not be changed. We suggest a curriculum aimed at educating general surgeons in acute neurosurgery.

InCHARGE: Co-creating, implementing and evaluating interventions to utilize nurses' competence and achieve person-centred fundamental care-A research protocol describing an action research approach.

AIM AND OBJECTIVES: This research protocol presents an action research project with the aim to demonstrate the value of person-centred fundamental care to nurses and nurse managers in surgical care units to encourage a far-reaching change in this direction. The objectives are to describe this process and to evaluate the effects on missed nursing care and person-centred fundamental care. METHODS: In a novel collaboration between nursing science and medical humanities the action research design will be used to interact with nursing staff and leaders in three surgical care units and design interventions with the purpose to affect the direction of nursing. Initially, the care units will be presented with interactive workshops including evidence-based education on person-centered fundamental care, person-centredness, nurse role responsibility and leadership. This will be followed by cocreation of interventions to stimulate person-centered fundamental care. The Fundamentals of Care framework will be used as the overarching theoretical framework. Data on missed nursing care, person-centred climate and person-centered fundamental care will be collected repeatedly from patient- and nursing stakeholders through interviews and validated questionnaires. Additionally, data from written reflections following clinical observations and focus group interviews will be included. The duration of the study will be approximately five years from ethical approval. DISCUSSION: It has been previously reported that the current working environments of registered nurses are forcing them to ration their caring responsibilities, leading to a lack of fulfillment of patients' fundamental care needs, with possible severe consequences for patients. The action research design helps researchers gain an understanding of the contextual factors important for forthcoming interventions, enabling reflective processes and cocreation of interventions with stakeholders. This may lead to feasible interventions and strengthen nursing leadership in the involved units.

Sleep in neurointensive care patients, and patients after brain tumor surgery.

BACKGROUND: Severely brain injured patients treated in the neuro intensive care unit (NICU) are usually sedated. Sedation may affect not only the ability to sleep, but also the EEG rhythms used to identify sleep. AIM: The aims were: To study if sleep patterns could be identified in the severely brain injured and sedated patients in the NICUTo study if sleep patterns could be identified in patients the night after brain tumor surgery in the neurointermediate care unit (NIMCU)To search for risk factors for not being able to sleep after brain tumor surgery. STUDY DESIGN: Two populations were included; one with patients affected by severe brain injury and one with patients who had undergone planned brain tumor surgery. This was a quantitative observational study using EEG. Eligible neurointensive care patients for this study had to be suffering from a neurosurgical condition (for example subarachnoid haemorrhage, acute subdural hematoma, intracerebral haemorrhage and meningitis), have affected consciousness and age over 18 years. Thirty-seven patients were included from NICU. Ninety-eight patients, with a suspected glioma (WHO grade II-IV) planned for surgery were also included. RESULTS: Neuro intensive care patients, sedated and treated in ventilator, showed no EEG sleep patterns at all. After brain tumor surgery, sleep occurred in 74% of the patients, despite frequent wake-up tests. The patients with sleep patterns were on average 8 years younger, p = 0.03. CONCLUSIONS: Patients with severe brain injury are at risk of having no sleep when treated at the NICU, whereas after brain tumor surgery, sleep occurs in three-fourths of the patients. Further studies and new methods are warranted to identify sleep and investigate how the loss of sleep affects these patients and how sleep disturbances can be managed.

A mentoring programme to meet newly graduated nurses' needs and give senior nurses a new career opportunity: A multiple-case study.

AIM: To evaluate the implementation of a multifaceted mentoring programme in a large university hospital and describe its value from the perspectives of newly graduated nurses, experienced nurses and the hospital organisation. BACKGROUND: Healthcare organisations need long-term competence-planning strategies to retain nurses, prevent their premature departure from the profession and use their competencies. This paper reports a mentoring programme focused on supporting newly graduated nurse' transition to practice and senior nurses' professional development as supervisors. DESIGN: A multiple-case study. METHODS: We performed 35 interviews with nurses, supervisors and nurse managers in the five units that implemented the programme, mapped the programme at the hospital level and extracted the nurses' working hours. The interviews were analysed thematically using the theoretical lens of the head-heart-hand model to interpret the results. RESULTS: Of 46 units in the hospital, 14 had implemented one or several of the components in the mentoring programme. The programme corresponded to the newly graduated nurses' needs, gave senior nurses a new career opportunity and contributed to an attractive workplace. The main theme, Giving new nurses confidence, experienced nurses a positive challenge and the organisation an opportunity to learn, reflects the value of the programme's supervisory model to new and experienced nurses and to the organisation as a whole. CONCLUSION: The mentoring programme appeared to be a promising way to smooth the transition for newly graduated nurses. The experienced supervising nurses were key to the success of this complex programme, supporting the new nurses at the bedside and being available to respond to their questions and reflections. Embedding the supervisors in the units' daily practice was necessary to the success of the different parts of the programme. Despite the strategic and well-designed implementation of this mentoring programme aimed to solve the everyday challenge of nurse shortages in the hospital, it was a challenge to implement it fully in all the units studied.

Electroencephalographic Patterns During Common Nursing Interventions in Neurointensive Care: A Descriptive Pilot Study.

BACKGROUND: Many patients with neurological insults requiring neurointensive care have an increased risk of acute symptomatic seizures. Various nursing interventions performed when caring for these patients may elicit pathological cerebral electrical activity including seizures and stimulus-induced rhythmic, periodic, or ictal discharges (SIRPIDs). The aim was to explore changes in electroencephalogram (EEG) due to neurointensive care nursing interventions. METHODS: A convenience sample was recruited between November 2015 and April 2016, consisting of 12 adult patients with impaired consciousness due to a neurosurgical condition. Continuous EEG and simultaneous video recordings of nursing interventions were collected 48 continuous hours for each patient. Two analysts categorized the video recordings for common nursing interventions, and a neurophysiologist analyzed the EEGs. RESULTS: In total, 976 nursing interventions were observed. Epileptiform activity was observed in 4 patients (33%), during 1 nursing intervention episode each (0.4%). The 4 observed episodes of epileptiform activity occurred during multiple simultaneous nursing interventions (n = 3) and hygienic interventions (n = 1). Stimulus-induced rhythmic, periodic, or ictal discharges were observed in 1 patient (8%), in 1 single nursing intervention (0.1%). The observed SIRPIDs occurred during repositioning of the patient. All patients had muscle artifacts, during 353 nursing interventions (36.3%). The duration of nursing interventions was longer for those with simultaneous muscle artifacts (median, 116 seconds) than those without muscle artifacts, epileptiform activity, or SIRPIDs (median, 89.0 seconds). With regard to epileptiform activity and SIRPIDs, the median durations of the nursing interventions were 1158 and 289 seconds, respectively. CONCLUSION: The results of this pilot study indicate that muscle artifacts seem prevalent during nursing interventions and may be a sign of stress. Nurses should be aware of the risk of inducing stress by performing regular nursing interventions in daily practice, consider shorter or fewer interventions at a time in sensitive patients, and administer sedation accordingly. Considering that this was a pilot study, more research that investigates correlations between EEG patterns and nursing interventions in larger samples is needed.

Predictive Factors That May Contribute to Secondary Insults With Nursing Interventions in Adults With Traumatic Brain Injury.

BACKGROUND: Nursing interventions pose risks and benefits to patients with traumatic brain injury at a neurointensive care unit. OBJECTIVES: The aim of this study was to investigate the risk of inducing high intracranial pressure (ICP) related to interventions and whether intracranial compliance, baseline ICP, or autoregulation could be used as predictors. METHODS: The study had a quantitative, prospective, observational design. Twenty-eight patients with TBI were included, and 67 interventions were observed. The definition of a secondary ICP insult was ICP of 20 mm Hg or greater for 5 minutes or more within a continuous 10-minute period. RESULTS: Secondary ICP insults related to nursing interventions occurred in 6 patients (21%) and 8 occasions (12%). Patients with baseline ICP of 15 mm Hg or greater had 4.7 times higher risk of developing an insult. The predictor with the best combination of sensitivity and specificity was baseline ICP. CONCLUSIONS: Baseline ICP of 15 mm Hg or greater was the most important factor to determine the risk of secondary ICP insult related to nursing intervention.

The influence of hyperthermia on intracranial pressure, cerebral oximetry and cerebral metabolism in traumatic brain injury.

BACKGROUND: Hyperthermia is a common secondary insult in traumatic brain injury (TBI). The aim was to evaluate the relationship between hyperthermia and intracranial pressure (ICP), and if intracranial compliance and cerebral blood flow (CBF) pressure autoregulation affected that relationship. The relationships between hyperthermia and cerebral oximetry (BtipO2) and cerebral metabolism were also studied. METHODS: A computerized multimodality monitoring system was used for data collection at the neurointensive care unit. Demographic and monitoring data (temperature, ICP, blood pressure, microdialysis, BtipO2) were analyzed from 87 consecutive TBI patients. ICP amplitude was used as measure of compliance, and CBF pressure autoregulation status was calculated using collected blood pressure and ICP values. Mixed models and comparison between groups were used. RESULTS: The influence of hyperthermia on intracranial dynamics (ICP, brain energy metabolism, and BtipO2) was small, but individual differences were seen. Linear mixed models showed that hyperthermia raises ICP slightly more when temperature increases in the groups with low compliance and impaired CBF pressure autoregulation. There was also a tendency (not statistically significant) for increased BtipO2, and for increased pyruvate and lactate, with higher temperature, while the lactate/pyruvate ratio and glucose were stable. CONCLUSIONS: The major finding was that the effects of hyperthermia on intracranial dynamics (ICP, brain energy metabolism, and BtipO2) were not extensive in general, but there were exceptional cases. Hyperthermia treatment has many side effects, so it is desirable to identify cases in which hyperthermia is dangerous. Information from multimodality monitoring may be used to guide treatment in individual patients.

Interference of the electrospray voltage on chromatographic separations using porous graphitic carbon columns.

The electrospray ionization (ESI) voltage is shown to interfere with liquid chromatographic separations performed with packed porous graphitic carbon (PGC) capillary columns. This interference is ascribed to the presence of an electric field over the conductive column in the absence of an earth point between the column and the ESI emitter. The current evolved alters the chromatographic behavior of the catecholamine metabolite 3-O-methyl-DOPA significantly, as both peak splitting and a dramatic decrease in the retention time were observed. Furthermore, the response from the mass spectrometer was decreased by 33% at the same time. A related compound, tyrosine, exhibited decreased retention times but no peak splitting, whereas no shifts in the retention times (or peak splitting) were seen for the less retained dopamine and noradrenaline. When the current through the PGC column was eliminated by the use of an earth point between the column and the ESI emitter, the chromatographic behavior of the column was found to return slowly to normal after hours of equilibration with 60 : 40 (v/v) methanol-ammonium formate buffer of pH 2.9. The behavior of the PGC column with and without the earth point was found to be highly reproducible during a period of 1 month. We propose that the effect of the ESI voltage on the chromatographic behavior of the PGC column is due to associated redox reactions affecting both the PGC particles and the analytes. It is concluded that (for analytical reasons), care should be taken to ensure that no current is flowing through the chromatographic system when interfacing PGC columns, and conducting parts in general, to ESI mass spectrometry.

Secondary insults related to nursing interventions in neurointensive care: a descriptive pilot study.

The patients at a neurointensive care unit are frequently cared for in many ways, day and night. The aim of this study was to investigate the amount of secondary insults related to oral care, repositioning, endotracheal suctioning, hygienic measures, and simultaneous interventions at a neurointensive care unit with standardized care and maximum attention on avoiding secondary insults. The definition of a secondary insult was intracranial pressure > 20 mm Hg, cerebral perfusion pressure < 60 mm Hg and systolic blood pressure < 100 mm Hg for 5 minutes or more in a 10-minute period starting from when the nursing intervention began. The insult minutes did not have to be consecutive. The study included 18 patients, seven women and 11 men, aged 36-76 years with different neurosurgical diagnoses. The total number of nursing interventions analyzed was 1,717. The most common kind of secondary insults after a nursing measure was high intracranial pressure (n = 93) followed by low cerebral perfusion pressure (n = 43) and low systolic blood pressure (n = 14). Repositioning (n = 39) and simultaneous interventions (n = 32) were the nursing interventions causing most secondary insults. There were substantial variations between the patients; only one patient had no secondary insult. There were, overall, a limited number of secondary insults related to nursing interventions when a standardized management protocol system was applied to reduce the occurrence of secondary insults. Patients with an increased risk of secondary insults should be recognized, and their care and treatment should be carefully planned and performed to avoid secondary insults.
