Nursing in Critical Care最新文献

Background: Vital signs assessment is critical for patient surveillance and safety. Research has found, however, that this assessment is often neglected in clinical practice. The reasons for this are unclear as few studies have explored this issue. Those studies that have are small, single site studies and found that culture and poor understanding are contributing factors.

Aim: The aim was to explore the link between the clinical neglect of vital signs assessment and patient mortality and provide a better understanding of factors influencing vital signs assessment in the context of acute patient care. Coroners' reports represent an untapped source of information regarding shortfalls in vital signs assessment. Using a framework analysis, an audit was conducted of the Australian National Coronial Information System for cases where vital signs' assessment was mentioned in coronial reports.

Results: Fifty-eight cases met the eligibility criteria, with deceased patients aged from 7 days to 93 years. Key themes related to absence of reassessment of vital signs, inappropriate delegation, passing responsibility to another staff member and not following policy.

Conclusions: The findings reflect a combination of individual and institutional failings and suggest that vital signs assessment was not considered a priority aspect of care.

Relevance to clinical practice: Vital signs assessment must be considered an essential aspect of clinical care in all patients. This important aspect of care should be emphasized across all domains of patient care.

Patients in delirium require trustful communication and re-orientation. We developed a flyer with positive, re-orientating suggestions for families of delirious patients in intensive care units. Suggestions include creating a safe environment, interpreting unusual behaviours positively and fostering mental resilience. Additionally, families are encouraged to prioritize their own well-being, recognizing their crucial role in supporting their loved ones. This flyer offers practical strategies across four key areas: ensuring security and orientation, reframing noises and body experiences, managing agitation and reshaping perceptions. By equipping families with knowledge and tools, this resource aims to promote understanding, resilience and strength to humanize delirium care.

Background: In recent decades, intra-aortic balloon pump (IABP) technology has made significant progress (sheathless insertion technique, different balloon diameters, percutaneous technique and fibre optic IABP) in reducing complications and increasing patient support. Nonetheless, IABP-related complications are still frequent and are associated with a poor prognosis.

Aim: The aim of this systematic review was to identify complications associated with IABP treatment in critically ill patients with a compromised cardiac function.

Study design: A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines based on searches in CINAHL (EBSCO), Medline and Embase (Ovid) from January 2012 to April 2023. Quantitative studies were included if they reported as their primary outcome(s) complications of IABP in adult patients because of cardiovascular conditions and were published in English, Norwegian, Swedish or Danish. Study selection, methodological quality assessment and data extraction were performed independently by two authors. The results were synthesized narratively.

Results: A total of nine studies were included in the review, most of which were retrospective (eight of nine). Bleeding was the most frequently occurring complication, followed by limb ischaemia, stroke, infection, IABP malfunction, haematoma and other vascular complications. In addition, a correlation between IABP duration and vascular complications was found in three out of nine studies. Lastly, the incidence rate of stroke was higher in patients with axillary IABP than in those with femoral IABP.

Conclusions: This systematic review revealed that bleeding and limb ischaemia were the two most frequent complications associated with IABP therapy. We identified a correlation between (a) IABP support time and the development of vascular complications and (b) stroke and implantation of IABP catheter in the axillary artery. Further studies are needed to explore these findings directly.

Relevance to clinical practice: Increasing critical care nurses' knowledge regarding complications related to IABP support could lead to early identification, potentially lowering the incidence rate of complications.

Background: Medical devices commonly used for the treatment and care of critically ill patients can cause pressure injuries in intensive care units (ICUs). The endotracheal tube (ETT) is one of the most common medical devices to cause pressure injuries.

Aim: This study investigated the incidence of, characteristics of and risk factors for ETT-related pressure injuries for ICU patients.

Study design: This study adopted a prospective descriptive research design. The sample consisted of 146 endotracheally intubated patients. Data were collected using a patient information form, an Endotracheal Tube-Related Pressure Injuries Assessment Form, the Braden Risk Assessment Tool and the Nutritional Assessment Test.

Results: The study revealed that 80.14% of the patients developed ETT-related pressure injuries. Over half of the ETT-related pressure injuries appeared on Day 3 or 4 (56.41%). High body mass index was found to be associated with the development of ETT-related pressure injuries (OR: 1.15, 95% CI: 1.05-1.26, p = .003). None of the other variables were statistically significant in the development of pressure injuries.

Conclusions: The incidence of ETT-related pressure injuries was quite high in the internal, surgical and anaesthesia ICUs. High body mass index was associated with the development of ETT-related pressure injuries. Intensive care nurses should implement interventions to prevent ETT-related pressure injuries in critically ill patients receiving mechanical ventilation support.

Relevance to clinical practice: ETT-related pressure injuries are common in ICU patients. High body mass index was associated with the development of ETT-related pressure injuries in critically ill patients. The skin and mucosa should be assessed for the development of ETT-related pressure injuries during the daily assessment of the patients receiving mechanical ventilation support. The ETT should be repositioned regularly, and the most suitable ETT fixation method should be used.

Background: Traumatic brain injuries (TBIs) are one of the leading causes of death or long-term disability around the world. As a result of improvements in supportive care, patients are surviving more severe insults with more pronounced dependency on their families, hospitals, and long-term care facilities. The introduction of brain tissue oxygenation (PbtO2) monitoring aims to recognize episodes of reduced cerebral perfusion with and without associated increased intracranial pressure (ICP).

Aim: The aim of this review is to determine the impact of PbtO2 on the Glasgow Outcome Scale/Glasgow Outcome Scale Extended (GOS/GOSE) in patients with moderate to severe TBI.

Study design: Systematic review with narrative and meta-analysis. All original research in which adult patients undergoing PbtO2 were compared with a control group of traditional ICP/cerebral perfusion pressure (CPP) monitoring. Both randomized controlled trials and observational studies were included in this review.

Methods: Databases were searched in September 2022. The primary outcome of the review was the impact of PbtO2 monitoring on GOS/GOSE, while secondary outcomes were mortality and length of stay (LOS) in the intensive care unit (ICU).

Results: Seven studies with a combined number of 770 patients were included in the review. These patients were adults ≥16 years of age. Only two of the studies included found a statistically significant association between PbtO2 monitoring and improved long-term neurological outcomes in patients with TBI (p = .01, p < .01). A meta-analysis of the secondary outcomes identified an associated reduction of mortality in favour of the group treated with PbtO2 monitoring (p < .0001). Results from studies examining LOS in ICU have demonstrated an associated increase of LOS in ICU in patients treated with PbtO2-guided therapy.

Conclusion: From the studies included in this review, only two found a statistically significant association between PbtO2 monitoring and long-term outcomes. It is unclear whether PbtO2 goal-directed therapy has a positive impact on the long-term neurological functions and mortality of patients suffering from TBI. A multicentre randomized controlled trial may provide further evidence, but not necessarily conclusive.

Relevance to clinical practice: Further research is warranted to determine the efficacy of the introduction of this new monitoring system to guide local policy change.

Background: Patient diaries are a supportive intervention aiding intensive care unit (ICU) survivors and their families post-critical illness. Despite their growing acceptance, ICU diary usage varies across settings.

Aim: This study explored themes in nurse-written ICU diaries and their impact on nursing work and communication.

Study design: This qualitative study employed an interpretative narrative methodology to explore the experiences of ICU nurses. The narrative approach enabled the synthesis of diverse events and impressions into coherent stories, facilitating a deeper understanding of participants' perspectives. Data collection involved thematic analysis of diaries following Braun and Clarke's methodology. The analysis included familiarization, coding, theme identification and validation by the research team. The findings were reviewed by participants and translated into English using the WHO's cultural adaptation guidelines, ensuring reliability and credibility in the study's outcomes.

Results: The sample consisted of 28 ICU nurses, each with professional experience ranging from 1 to 23 years. The hospitalized subjects for whom our sample wrote the diary consist of 13 participants aged 23-79 years. Two main themes emerged from the analysis: (1) simplifying the intensive care situation with specific minimization strategies and (2) attention to nonverbal communication.

Conclusions: This study highlights the role of nurse-written ICU diaries in making the ICU environment more understandable and less intimidating for patients. Nurse-written ICU diaries contribute to improved communication and emotional support within the ICU environment. Further research is needed to explore these effects more fully and to assess the broader implications of ICU diaries on patient outcomes.

Relevance to clinical practice: Nurse-written intensive care unit (ICU) diaries have a significant impact on both patient care and nursing practice in ICUs. ICU diaries serve as a crucial tool for enhancing communication, emotional support and empathetic care within these high-stress environments. By simplifying complex medical information and focusing on nonverbal communication, nurses can make the ICU experience more comprehensible and less intimidating for patients. This approach reduces patient anxiety and psychological stress while fostering a stronger nurse-patient relationship, ultimately improving care quality.

Background: Patient-ventilator asynchrony (PVA) is a condition that commonly affects patients who are mechanically ventilated. PVA happens when the patient's own breathing effort and the ventilator preset settings are out of sync. Ventilator waveform monitoring is viewed as a difficult undertaking, even for experienced practitioners, despite being a non-invasive and reliable tool for diagnosing PVA.

Aim: To assess the knowledge levels and attitudes of critical care nurses (CCNs) regarding the use of ventilator waveform monitoring to detect PVA.

Study design: A cross-sectional online survey was conducted in three intensive care units (ICUs) in Alexandria, Egypt. The questionnaire consisted of four parts to evaluate CCNs' level of knowledge and attitude regarding ventilator waveform monitoring and assess their ability to detect PVA.

Results: Of the 137 CCNs approached, 101 CCNs completed the survey, resulting in a 73.7% response rate. Most nurses (88.1%) demonstrated poor knowledge levels and negative attitudes (93.1%) towards using waveform monitoring to detect PVA. A significant relationship was found between nurses' knowledge of ventilator waveform monitoring and their participation in previous training programmes on mechanical ventilation (MV; p = .031). Additionally, nurses' attitudes towards ventilator waveform monitoring were significantly associated with their level of education (p = .002) and attendance in previous courses on waveform analysis (p = .020).

Conclusions: A majority of CCNs have poor knowledge and negative attitudes regarding ventilator waveform monitoring. Previous training in MV and attendance courses on ventilator waveform analysis showed a significant correlation between nurses' level of knowledge and attitudes regarding ventilator waveform monitoring.

Relevance to clinical practice: Assessment of CCNs' knowledge and attitudes regarding ventilator waveform monitoring for detecting patient-ventilator asynchrony (PVA) informs the development of future educational programmes, ultimately aiding in the delivery of prompt and high-quality care.

The purpose of this study was to evaluate the effect of cold application on amiodarone-related vein phlebitis. A quasi-experimental design was used. The study sample consisted of 79 patients who received an amiodarone infusion. The control group of the study consisted of patients receiving amiodarone treatment, while the intervention group consisted of patients receiving cold application during the amiodarone infusion. In the intervention group, after the start of amiodarone treatment, cold gel packs were applied a total of 12 times for 15 min at 2-h intervals. The rate of phlebitis development was 59% in the intervention group and 95% in the control group (p < .001). It was found that 52.2% of the patients in the intervention group had first grade phlebitis and 84.4% of the patients in the control group who developed phlebitis had second grade phlebitis (p < .001). The 15-min cold application was found to be effective in terms of the rate of phlebitis development, phlebitis grade and time of phlebitis development. (ClinicalTrials.gov NCT05058053).

Background: Deep sedation may be indicated in the intensive care unit (ICU) for the management of acute organ failure, but leads to sedative-induced delirium. Whether processed electroencephalography (p-EEG) is useful in this setting is unclear.

Aim: To describe the PSI index in deeply sedated critically ill patients with acute organ failure, and to examine a potential association between low PSI values and ICU delirium. [Correction added on 16 October 2024, after first online publication: Aim subsection in Abstract has been added on this version.] METHODS: We conducted a single-centre observational study of non-neurological ICU patients sedated according to a standardized guideline of deep sedation (Richmond Agitation Sedation Scale [RASS] between -5 and -4) during the acute phase of respiratory and/or cardio-circulatory failure. The SedLine (Masimo Incorporated, Irvine, California) was used to monitor the Patient State Index (PSI) (ranging from 0 to 100, <25 = very deep sedation and >50 = light sedation to full awareness) during the first 72 h of care. Delirium was assessed with the Confusion Assessment Method for the Intensive Care Unit (CAM-ICU).

Results: The median duration of PSI monitoring was 43 h. Patients spent 49% in median of the total PSI monitoring duration with a PSI <25. Patients with delirium (n = 41/97, 42%) spent a higher percentage of total monitored time with PSI <25 (median 67% [19-91] vs. 47% [12.2-78.9]) in non-delirious patients (p .047). After adjusting for the cumulative dose of analgesia and sedation, increased time spent with PSI <25 was associated with higher delirium (odds ratio 1.014; 95% CI 1.001-1.027, p = .036).

Conclusions: A clinical protocol of deep sedation targeted to RASS at the acute ICU phase may be associated with prolonged EEG suppression and increased delirium. Whether PSI-targeted sedation may help reducing sedative dose and delirium deserves further clinical investigation.

Relevance to clinical practice: Patients requiring deep sedation are at high risk of being over-sedated and developing delirium despite the application of an evidence-based sedation guideline. Development of early objective measures are essential to improve sedation management in these critically ill patients.
