Effectiveness of Nursing Interventions to Prevent Dry Eye in Critically Ill Patients

Evaluation of the Knowledge, Attitudes, and Practices of Intensive Care Unit Nurses Regarding Eye Care: A Descriptive Study

Eye care is an essential component of nursing practices in intensive care units (ICUs) due to the vulnerability of critically ill patients to ocular complications. The study aims to evaluate ICU nurses' knowledge, attitudes, and practices regarding eye care. This descriptive study, involved 207 ICU nurses from Turkey. Data were collected using the Nurse Introductory Information Form and the Eye Care Clinical Competence Questionnaire. The nurses' mean age was 34.37 ± 7.81. The study found that 54.1% did not record eye problems, and 25% cited excessive paperwork as a barrier. Nurses who followed current studies scored higher on the Eye Care Clinical Competence Questionnaire (p = 0.036). Additionally, holding an intensive care certificate significantly improved application sub-dimension and total scale scores (p = 0.020, p = 0.023). Educational level significantly impacts ICU nurses' ability to provide eye care, though they face various obstacles in its delivery.

Impact of nursing interventions on the prevention of ocular surface disorders in critical care patients: A systematic review

BACKGROUND

Intensive care unit (ICU) patients are at an increased risk of ocular surface injuries because of various factors such as reduced tear production and impaired protective mechanisms. Despite the significance of ocular care in ICU settings, there is a lack of consensus on effective interventions, leading to inadequate prevention of ocular surface disease (OSD).

AIM

This systematic review aimed to assess the effectiveness of nursing eye care in preventing OSD in ICU patients. Secondary objectives included identifying primary risk factors for ocular injuries and examining the most effective preventive methods.

STUDY DESIGN

A systematic review following PRISMA guidelines was conducted, encompassing a literature search, article selection, quality assessment and data synthesis. Studies meeting inclusion criteria were observational studies and clinical trials, focusing on adults admitted to ICUs under sedation and receiving mechanical ventilation.

RESULTS

Of 3545 initially identified articles, 12 studies met inclusion criteria. These studies involved a total of 1853 participants. Various interventions were assessed, including saline rinsing, lubricating drops, gel lubricants, occlusion with polyethylene dressing, passive blinking and eyelid closure with tape. Moist chamber occlusion every 6 h combined with gel lubrication emerged as the most effective method in preventing OSD.

CONCLUSIONS

Gel lubrication along with moist chamber occlusion proved to be the most effective strategy in preventing ocular injuries in ICU patients. Conversely, the routine use of physiological saline was associated with increased severity of corneal lesions. Properly defined protocols and well-trained nursing teams are crucial for reducing ocular injuries in ICU settings.

RELEVANCE TO CLINICAL PRACTICE

The findings underscore the importance of implementing evidence-based eye care protocols in ICUs, emphasizing the use of gel lubrication and ocular surface protection to mitigate the risk of OSD. This highlights the need for comprehensive training programmes for ICU nursing staff to ensure optimal ocular care delivery.

Causal validation of the risk for corneal injury in critically ill adults

BACKGROUND

The validity of a nursing diagnosis depends on a continuous investigation process in different populations to provide clinical evidence. The risk for corneal injury nursing diagnosis was approved in 2013 and only reviewed in 2017, demonstrating the need to perform a clinical validation to improve it.

AIM

To perform a causal validation of the risk for corneal injury nursing diagnosis in critically ill adults.

STUDY DESIGN

A prospective cohort study was performed in two intensive critical care units in Northern Brazil with adults aged over 18 years without corneal injury at admission. The patients were evaluated for 10 days, using a data collection tool composed of risk factors for the risk for corneal injury nursing diagnosis. The independent variables were described through absolute and relative frequency. The accuracy measures and risk factors were identified through Cox regression, considering a 95% confidence interval.

RESULTS

The nurses assessed 209 critically ill adults and identified that 76.0% of them presented the risk for corneal injury nursing diagnosis, with 16.3% developing a corneal injury, all having previously presented the risk for corneal injury nursing diagnosis. The risk factors identified were eyeball exposure (hazard ratio: 1.78; 95% CI: 1.27-2.51), Glasgow score < 6 (hazard ratio: 1.73; 95% CI: 1.15-2.60) and periorbital oedema (hazard ratio: 1.43; 95% CI: 1.03-1.99), with these factors showing high specificity, and the mechanical ventilation variable, showing high sensitivity, with ROC curve of .86.

CONCLUSION

Eyeball exposure, Glasgow score < 6 and periorbital oedema are the risk factors of the risk for corneal injury nursing diagnosis, in critically ill adults. These risk factors guide nursing interventions. This causal validation can improve the risk for corneal injury nursing diagnosis levels of evidence in the NANDA International Taxonomy.

RELEVANCE TO CLINICAL PRACTICE

It is necessary to guide nursing interventions for critically ill adults with lowered level of consciousness and corneal exposure for the prevention of corneal injury.

[Use of dexpanthenol in corneal damage]

Issues of regeneration of the cornea, which is the most vulnerable structure of the eyeball, suffering from various diseases and injuries, burns, when wearing contact lenses and glaucoma, are highly relevant for ophthalmologists. It is also necessary to minimize damage and stimulate corneal epithelization during and after the use of steroidal and non-steroidal anti-inflammatory drugs, antibacterial drugs and antiseptics, which have a cytotoxic effect and often inhibit regeneration processes, potentially even leading to the development of corneal epithelial defects. This review analyzes the effectiveness of a promising drug 5% dexpanthenol in terms of improving the reparative processes and the function of epithelial cells.

Nursing care to COVID-19 patients on hemodialysis and in prone position: an experience report

OBJECTIVE

To describe the experience report of a nurse providing care to COVID-19 patients on hemodialysis and in prone position.

METHOD

Experience report. This study was conducted in a philanthropic hospital in a Brazilian capital from May to August 2020 during the Coronavirus pandemic.

RESULTS

The nurse has faced several challenges concerning structure, material, human resources, and care when treating COVID-19 patients on hemodialysis and in prone position. Management based on dialogue and shared evidence-based information and implementation of a new care protocol were a foundation for care reorganization of the Nursing team for providing care to COVID-19 patients.

CONCLUSION

This experience emphasizes the importance of nursing care to patients' responses, with actions based on care protocols, strengthening human relations. The conduction of different study designs is necessary to contribute to an improved nursing care and survival of patients experiencing COVID-19 complications.

Comparative efficacy of various preventive methods for exposure keratopathy among critically ill patients: A network meta-analysis of randomized controlled trials

BACKGROUND

There is a wide variety of preventive methods currently available for the treatment of exposure keratopathy. Because of a lack of evidence from head-to-head randomized controlled trials (RCTs), the relative effects of these preventive methods in exposure keratopathy patients remain unclear. The purpose of our study is to carry out a network meta-analysis comparing the efficacy of different methods for the prevention of exposure keratopathy and rank these nursing methods for practical consideration.

METHODS

A literature search was performed of the MEDLINE (PubMed), EMBASE, Web of Science, China National Knowledge Infrastructure Library (CNKI), China Science and Technology Journal Database (Weipu), WanFang Database and China Biology Medicine disc. Two authors independently extracted data from each included RCTs according to a predesigned Excel spreadsheet and assessed the methodological quality of included RCTs using the Cochrane risk of bias tool. Data was analyzed using the R (V.3.6.2) and the Stata (V.15.0).

RESULTS

21 RCTs involving 2022 patients and evaluating 11 preventive methods were included. Rankings based on posterior probabilities revealed that artificial tear ointment might be the best way to prevent exposure keratopathy (35%), polyethylene covers might be the second-best (31%), swimming goggles might be the third-best (21%), foam dressing might be the fourth-best (18%).

CONCLUSIONS

This network meta-analysis indicated that artificial tear ointment, polyethylene covers, swimming goggles and foam dressing might be selected for the prevention of exposure keratopathy in intensive care unit patients, which is important in future research. Although evidence is scant, more attention should be paid to head-to-head comparisons of the most commonly used prevention methods in this field.

Risk for corneal injury in intensive care unit patients: A cohort study

AIM

To identify the incidence and risk factors for corneal injury amongst critically ill patients.

METHOD

A prospective cohort study with adult patients from one intensive care unit in Northern Brazil. Logistic regression was performed to predict the risk factors associated with corneal injury.

RESULTS

Data from 149 patients revealed 18.8% (28/149) corneal injuries. Factors independently associated with corneal injury were patients with eyeball exposure (OR: 27.31; 95% CI: 3.50-212.78); lagophthalmos (OR: 17.15; 95% CI: 5.78-50.85); chemosis (OR: 7.39; 95% CI: 2.28-23.97), periorbital oedema (OR: 7.99; 95% CI: 2.19-29.13) and hospitalisation >7-days (OR: 11.96; 95% CI: 3.27-43.66) had a significantly higher risk of developing corneal injury in this ICU.

CONCLUSION

Corneal injury was a common complication amongst critically ill patients and was associated with altered physiological function of the eyes such as exposure, lagophthalmos, chemosis and periorbital oedema. This study suggests introduction of a corneal injury prevention protocol for nursing and adding lagophthalmos and chemosis to the NANDA-I Taxonomy, thus contributing to the assessment and monitoring for the risk for corneal injury in critically ill patients.
