The impact of two distinct endotracheal tube fixation on the formation of pressure ulcer in the intensive care unit: A randomised controlled trial

Risk factors for oral mucosal pressure injury associated with endotracheal tubes in intensive care unit patients: A single-centre longitudinal study with brief follow-up

BACKGROUND

In intensive care units (ICUs), endotracheal tubes (ETTs) cause injury to the oral mucosa through friction and pressure. The incidence and risk factors of oral mucosal pressure injuries (PIs) have gained increasing attention in recent years.

AIM

The study aimed to identify risk factors for oral mucosal PIs associated with ETTs.

STUDY DESIGN

This was a single-centre brief follow-up longitudinal study conducted from January to May 2022. It recruited 250 patients without oral mucosal PIs who received mechanical ventilation support via ETT and were hospitalized in the ICU of a teaching and research hospital in Turkey. Receiver operating characteristic (ROC) analysis was performed to estimate the onset time of oral mucosal PI using the ETT repositioning time as an independent variable.

RESULTS

Oral mucosal PIs associated with ETT developed in 41.6% of patients. Of the 250 endotracheally intubated patients, the mean Acute Physiology and Chronic Health Evaluation (APACHE-II) score was 27.5 (min/max: 18/42), the mean length of stay (LOS) in the ICU was 24 days (min/max: 13/80). The median body mass index (BMI) of patients with oral mucosal PIs was (24.59 [IQR = 3.81] kg/m2), significantly lower than the median BMI of patients without oral mucosal PIs (26.62 [IQR = 5.93] kg/m2) (Z = 4.200; p < .001). The earliest onset of oral mucosal PIs was noted at 16 h after the start of follow-up, and the latest was 208 h after the start of follow-up, with a median of 160 (IQR = 48) h (approximately 6.7 days). Patients whose ETT was repositioned after 10.5 h had a higher risk of developing oral mucosal PIs (OR = 3.77; 95% CI: 2.65-5.37; p < .001). The decision tree (CHAID) method was applied to determine the time required to reposition the ETT to prevent oral mucosal PIs. The decision tree correctly classified the occurrence of oral mucosal PIs by 60.6% and the non-occurrence of oral mucosal PIs by 97.9%. Patients with parenteral nutrition and a low frequency of ETT repositioning time had a higher risk of oral mucosal PIs (p < .001).

CONCLUSIONS

Parenteral nutrition support and ETT repositioning timing were the primary risk factors for developing oral mucosal PIs. Close monitoring of endotracheally intubated patients receiving parenteral nutrition is essential, with particular attention to forming oral mucosal PIs. Additionally, repositioning the ETT at intervals of no more than 8 h may help reduce the risk of oral mucosal PI development.

RELEVANCE TO CLINICAL PRACTICE

As ICU patients are particularly vulnerable to mucosal membrane PIs, recognizing the associated risk factors is crucial for early detection and prevention. This study highlights the specific risk factors for oral mucosal PIs, equipping nurses with the knowledge to develop targeted interventions to prevent these injuries.

Global, regional and national burden of decubitus ulcers in 204 countries and territories from 1990 to 2021: a systematic analysis based on the global burden of disease study 2021

Background

Decubitus ulcers, also known as pressure ulcers, pose a significant public health challenge due to their substantial impact on morbidity, mortality, and healthcare expenditures.

Methods

The number and age-standardized rates (ASRs) of prevalence, death, disability adjusted life-year (DALY), years of life lost (YLL), and years lived with disability (YLD) at the global, regional, and national levels were acquired from the GBD 2021 database. Trends were evaluated based on the estimated average percentage change (EAPC) of ASRs. Additionally, data were stratified by socio-demographic index (SDI) quantiles, regions, countries, territories, and age groups.

Results

The total number of decubitus ulcer cases increased from 300,442 in 1990 to 645,588 in 2021. The global ASR of prevalence decreased slightly from 8.25 to 7.92 per 100,000 persons, with most cases occurring in individuals aged 60 and older. Deaths due to decubitus ulcers rose from 16,622 in 1990 to 37,033 in 2021, while the global ASR of death declined from 0.53 to 0.46 per 100,000 persons. DALY due to decubitus ulcers increased, exhibiting significant variation across regions and age groups. A higher SDI was correlated with increased ASRs of prevalence (R = 0.488, p < 0.001) and YLD (R = 0.495, p < 0.001). Conversely, a higher SDI was correlated with lower ASRs of death (R = -0.329, p < 0.001), DALY (R = -0.398, p < 0.001), and YLL (R = -0.445, p < 0.001).

Conclusion

The global burden of decubitus ulcers has risen, with notable regional and age-related disparities. This study offers valuable insights for policymakers to optimize healthcare strategies and mitigate the public health impact of decubitus ulcers.

Dressings and topical agents for preventing pressure ulcers

BACKGROUND

Pressure ulcers occur when people cannot reposition themselves to relieve pressure over bony prominences. They are difficult to heal, costly, and reduce quality of life. Dressings and topical agents (lotions, creams, and oils) for pressure ulcer prevention are widely used. However, their effectiveness is unclear. This is the third update of this review.

OBJECTIVES

To evaluate the effects of dressings and topical agents on pressure ulcer prevention, in people of any age without existing pressure ulcers, but at risk of developing one, in any healthcare setting.

SEARCH METHODS

We used the Cochrane Wounds Specialised Register, CENTRAL, MEDLINE, two other databases, and two trial registers, together with reference checking, citation searching, and contact with study authors to identify the studies that are included in the review. The latest search date was November 2022. We imposed no restrictions on language, publication date, or setting.

SELECTION CRITERIA

We included randomised controlled trials that enroled people at risk of developing a pressure ulcer.

DATA COLLECTION AND ANALYSIS

We used standard Cochrane methodological procedures.

MAIN RESULTS

In this update, we added 33 new studies, resulting in a total of 51 trials (13,303 participants). Of these, 31 studies involved dressings, 16 topical agents, and four included both dressings and topical agents. All trials reported the primary outcome of pressure ulcer incidence. Dressings Pressure ulcer incidence We made a total of 13 comparisons with 9027 participants. We present seven prioritised comparisons in the summary of findings (SoF) tables, as follows: silicone foam dressing versus no dressing (18 trials, 5903 participants; risk ratio (RR) 0.50, 95% confidence interval (CI) 0.33 to 0.77); foam dressing versus film dressing (3 trials, 569 participants; RR 0.72, 95% CI 0.20 to 2.67); hydrocellular foam dressing versus hydrocolloid dressing (1 trial, 80 participants; RR not estimable); silicone foam dressing type 1 versus silicone foam dressing type 2 (2 trials, 376 participants; RR 0.80, 95% CI 0.56 to 1.15); foam dressing versus fatty acid (2 trials, 300 participants; RR 1.67, 95% CI 0.49 to 5.72); polyurethane film versus hydrocolloid dressing (1 trial, 160 participants; RR 0.58, 95% CI 0.24 to 1.41); and hydrocolloid dressing versus no dressing (2 trials, 230 participants; RR 0.60, 95% CI 0.46 to 0.78). All low or very low-certainty evidence. The evidence is very uncertain about the effect of dressings on pressure ulcer development. Pressure ulcer stage Three comparisons reported pressure ulcer (PU) stage. Silicone foam dressing versus no dressing: PU stage 1 (8 trials, 1823 participants; RR 0.32, 95% CI 0.13 to 0.79); PU stage 2 (10 trials, 2873 participants; RR 0.47, 95% CI 0.30 to 0.73); PU stage 3 (3 trials, 718 participants; RR 0.45, 95% CI 0.06 to 3.21); PU stage 4 (2 trials, 610 participants; RR 0.21, 95% CI 0.02 to 1.77); unstageable PU (1 trial, 366 participants; RR 0.20, 95% CI 0.01 to 4.09); deep tissue injury (3 trials, 840 participants; RR 0.32, 95% CI 0.09 to 1.08). Foam dressing versus film dressing: PU stage 1 (1 trial, 270 participants; RR 0.56, 95% CI 0.39 to 0.80); PU stage 2 (1 trial, 270 participants; RR 1.00, 95% CI 0.06 to 15.82); deep tissue injury (1 trial, 270 participants; RR 0.67, 95% CI 0.11 to 3.93). Hydrocolloid dressing versus no dressing: PU stage 1 (1 trial, 108 participants; RR 0.54, 95% CI 0.31 to 0.94); PU stage 2 (1 trial, 108 participants; RR 0.86, 95% CI 0.28 to 2.66). All low or very low-certainty evidence. The evidence is very uncertain about the effect of dressings on different stages of pressure ulcer development. Adverse events One comparison reported adverse events: silicone foam dressing versus no dressing (3 trials, 2317 participants; RR not estimable; very low-certainty evidence). Silicone foam dressings may have little to no effect on the incidence of adverse events, but the evidence is very uncertain. Topical agents Pressure ulcer incidence We evaluated seven comparisons with 4276 participants. We present five prioritised comparisons in the SoF tables as follows: fatty acid versus placebo (6 trials, 2201 participants; RR 0.86, 95% CI 0.54 to 1.36); fatty acid versus usual care (7 trials, 1058 participants; RR 0.64, 95% CI 0.46 to 0.84); cream versus fatty acid (1 trial, 120 participants; RR 3.00, 95% CI 0.32 to 28.03); cream versus placebo (3 trials, 513 participants; RR 1.18, 95% CI 0.59 to 2.36); and cream versus usual care (1 trial, 47 participants; RR 1.60, 95% CI 0.84 to 3.04). All very low-certainty evidence. It is very uncertain whether they make any difference to PU development. Pressure ulcer stage Two comparisons reported PU stage. Fatty acid versus usual care: PU stage 1 (2 trials, 180 participants; RR 1.00, 95% CI 0.49 to 2.03); PU stage 2 (2 trials, 180 participants; RR 0.19, 95% CI 0.07 to 0.53). Cream versus placebo: PU stage 3 (1 trial, 258 participants; RR 1.25, 95% CI 0.34 to 4.55); PU stage 4 (1 trial, 258 participants; RR 0.33, 95% CI 0.01 to 8.11). Both low or very low-certainty evidence. It is uncertain whether they make any difference to the stage of PU development. Adverse events One comparison reported adverse events: fatty acid versus placebo (3 trials, 967 participants; RR 4.38, 95% CI 0.50 to 38.30; very low-certainty evidence). Fatty acid may have little to no effect on the incidence of adverse events compared to placebo, but the evidence is very uncertain. Risk of bias and imprecision were the main reasons for downgrading the certainty of the evidence.

AUTHORS' CONCLUSIONS

The included studies tested a wide variety of dressings and topical agents. The evidence for all interventions is uncertain or very uncertain; thus, it is unclear whether any of the dressings or topical agents studied make any difference to pressure ulcer development. Future studies should engage with stakeholders to determine priority interventions.

Incidence, characteristics and risk factors of endotracheal tube-related pressure injuries in intensive care units

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.

Evaluation of the effectiveness of preventive nursing measures for pressure injuries in patients in the neurology intensive care unit

BACKGROUND

Patients in neurology intensive care units (ICU) are prone to pressure injuries (PU) due to factors such as severe illness, long-term bed rest, and physiological dysfunction. PU not only causes pain and complications to patients, but also increases medical burden, prolongs hospitalization time, and affects the recovery process.

AIM

To evaluate and optimize the effectiveness of pressure injury prevention nursing measures in neurology ICU patients.

METHODS

A retrospective study was conducted, and 60 patients who were admitted to the ICU of the Department of Neurology were selected and divided into an observation group and a control group according to the order of admission, with 30 people in each group. The observation group implemented pressure injury prevention and nursing measures, while the control group adopted routine care.

RESULTS

Comparison between observation and control groups following pressure injury prevention nursing intervention revealed significantly lower incidence rates in the observation group compared to the control group at 48 h (8.3% vs 26.7%), 7 d (16.7% vs 43.3%), and 14 d (20.0% vs 50.0%). This suggests a substantial reduction in pressure injury incidence in the observation group, with the gap widening over time. Additionally, patients in the observation group exhibited quicker recovery, with a shorter average time to get out of bed (48 h vs 72 h) and a shorter average length of stay (12 d vs 15 d) compared to the control group. Furthermore, post-intervention, patients in the observation group reported significantly improved quality of life scores, including higher scores in body satisfaction, feeling and function, and comfort (both psychological and physiological), indicating enhanced overall well-being and comfort following the implementation of pressure injury prevention nursing measures.

CONCLUSION

Implementing pressure injury preventive care measures for neurology ICU patients will have better results.

Effects of cluster nursing interventions on the prevention of pressure ulcers in intensive care units patients: A meta-analysis

A meta-analysis was conducted to comprehensively evaluate the impact of cluster nursing interventions on the prevention of pressure ulcers (PUs) in intensive care unit (ICU) patients. Computer searches were performed in databases including Embase, Google Scholar, Cochrane Library, PubMed, Wanfang and China National Knowledge Infrastructure for randomized controlled trials (RCTs) implementing cluster nursing interventions for PUs prevention in ICU patients, with the search period covering the database inception to November 2023. Two researchers independently screened the literature, extracted data and conducted quality assessments. Stata 17.0 software was employed for data analysis. Overall, 17 RCTs involving 1463 ICU patients were included. The analysis showed that compared with conventional nursing, cluster nursing interventions significantly reduced the incidence of PUs (odds ratio: 0.24, 95% confidence intervals [CI]: 0.17-0.34, p < 0.001) and also significantly improved the levels of anxiety (standardized mean difference [SMD]: -1.39, 95% CI: -1.57 to 1.22, p < 0.001) and depression (SMD: -1.64, 95% CI: -2.02 to 1.26, p < 0.001) in ICU patients. This study indicates that the application of cluster nursing interventions in ICU patients can effectively reduce the incidence of PUs, as well as improve patients' anxiety and depression levels, thereby enhancing their quality of life, which is worth clinical promotion and application.

Impact of two endotracheal tube fixation on the incidence of peri-oral lesions: Elastic adhesive strips versus cord in a protective sheath. Study protocol for a cluster cross-over randomized trial

BACKGROUND

Endotracheal tube fixation in ventilated patients must be appropriate to ensure security during mechanical ventilation and prevent skin lesions. The incidence of endotracheal tube-caused pressure ulcers ranges from 7% to 45%. Various endotracheal tube fixations are used in intensive care units (ICUs) worldwide. By pressure exercised on the skin, these systems could lead to mucosal and skin peri-oral lesions. The main objective of this study is to evaluate the impact of the two fixation systems most commonly used in French ICUs (adhesive elastic band versus fixation cord with PolyVinyl Chloride (PVC) sheath) on the incidence of these peri-oral skin lesions.

METHODS

This studyis a multicenter, open-label, controlled, superiority, cluster cross-over randomized trial. 768 patients will be recruited in the 16 ICUs involved. The inclusion of patients will be carried out over two 12-month periods. Each site begins with one of the evaluated fixation systems: elastic adhesive tape or cord associated with a protective sheath. After a 4-month break, each site switches to the other fixation system. The primary outcome is the development of at least one peri-oral lesion during the first ten days of maintaining an orally inserted endotracheal tube. The presence of lesions is assessed by a blinded adjudication committee using photographs taken daily.

DISCUSSION

This study is the first multicenter, randomized trial designed to evaluate the impact of elastic adhesive tape versus fixation cord with PVC sheath on the incidence of peri-oral lesions. The results will provide data which could change and standardize care practices.

Effect of local oxygen therapy combined with vacuum sealing drainage on the healing of stage IV sacrococcygeal pressure ulcers

The present study aimed to investigate the effect of local oxygen therapy combined with vacuum sealing drainage (VSD) on the healing of stage IV pressure ulcers sacrococcygeal. In this prospective study, we included a total of 98 patients with stage IV sacrococcygeal pressure ulcers in our hospital between February 2021 and June 2022. The patients enrolled were randomly and equally divided into two groups: the study group (undergoing local oxygen therapy combined with VSD treatment) and the control group (receiving conventional treatment). The wound healing time and hospital stay were compared between the two groups. Additionally, the wound area, tissue type, wound exudation and pain intensity were assessed before treatment, 10, 20, 30 and 40 days after treatment. The incidence of complications was also calculated. The study group demonstrated significantly shorter wound healing time and hospital stays compared to the control group (p < 0.05). Before treatment, there were no significant differences in terms of wound area, tissue type and wound exudation between the two groups (p > 0.05); after 10, 20, 30 and 40 days of treatment, however, evidently smaller wound areas, improved tissue types and reduced wound exudation were observed in the study group compared to the control group (p < 0.05). Furthermore, the study group exhibited increased microvascular count compared to the control group (p < 0.05). Before treatment, there was no significant difference in pain intensity between the two groups (p > 0.05), whereas markedly lower pain intensity was seen in the study group than in the control group after 10, 20, 30 and 40 days of treatment (p < 0.05). The incidence of complications did not significantly differ between the two groups after 40 days of treatment (p > 0.05). Local oxygen therapy combined with VSD was found to effectively accelerate the healing process of stage IV sacrococcygeal pressure ulcers, leading to shorter hospital stays and improved patient prognosis. This combined therapy shows promise for widespread application in clinical practice.
