Pharmacological and non-pharmacological interventions to promote sleep in intensive care units: a critical review.

PURPOSE: Although it is generally recognized that poor sleep is common in the intensive care unit (ICU), it is still unclear which interventions can effectively improve sleep in this setting. In this review, we critically analyze the various pharmacological and non-pharmacological measures that have been proposed to tackle this problem. METHODS: A search of MEDLINE/PubMed, SciELO, and the Brazilian Virtual Library in Health (LILACS and BNDEF) databases was performed. Results were reviewed and 41 articles on pharmacological and non-pharmacological interventions to promote sleep in ICU were analyzed. RESULTS: Non-pharmacological interventions including eye mask and earplugs, bundles to reduce noise and lighting, and organization of patient care were shown to improve subjective and objective sleep quality, although the level of evidence was considered low. Assist-control ventilation was associated with a greater objective sleep quality than spontaneous modes, such as pressure support ventilation and proportional assist ventilation. Among pharmacological interventions, a moderate level of evidence was found for oral melatonin, with increases in both objective and subjective sleep quality. Continuous nocturnal infusion of dexmedetomidine was reported to increase sleep efficiency and favorably modify the sleep pattern, although evidence level was moderate to low. CONCLUSIONS: Several non-pharmacological and pharmacological measures can be helpful to improve sleep in critical patients. Further high-quality studies are needed to strengthen the evidence base.

Prognostic clinical indicators of short-term survival for ineffective breathing pattern in children with acute respiratory infection.

AIMS AND OBJECTIVES: To identify prognostic clinical indicators of short-term survival for ineffective breathing pattern in children with acute respiratory infection. BACKGROUND: Despite the studies of survival for nursing diagnosis, there is not enough evidence about the clinical indicators that are associated with a worse prognosis for ineffective breathing pattern. DESIGN: A prospective cohort study. METHODS: One hundred and thirty-six children were followed up for a minimum of six and a maximum of 10 consecutive days. The survival rate for ineffective breathing pattern was calculated using Nelson-Aalen's method. An extended Cox model was adjusted to identify the main prognostic clinical indicators for this nursing diagnosis. RESULTS: Over half of the sample had an ineffective breathing pattern at the first evaluation. The occurrence of new cases was observed until the ninth day of monitoring, and the survival rate after this day was low. According to the Cox model, the main clinical indicators of a poor prognosis were an abnormal breathing pattern, the use of accessory muscles, dyspnoea and increase in the anterior-posterior chest diameter. CONCLUSIONS: Children with acute respiratory infection who present with an abnormal breathing pattern, the use of accessory muscles to breathe, dyspnoea and increased anterior-posterior diameter have a poor prognosis for an ineffective breathing pattern. RELEVANCE TO CLINICAL PRACTICE: Survival analyses of nursing diagnoses allow the identification of clinical indicators that can be used in clinical practice as prognostic markers. The identification of indicators associated with a poor clinical prognosis allows nurses to intervene early and to maximise the possibility of a good outcome.

Clinical Differentiation of Respiratory Nursing Diagnoses among Children with Acute Respiratory Infection.

The aim of this study was to identify the defining characteristics that allow clinical differentiation of the nursing diagnoses, ineffective breathing pattern (IBP), ineffective airway clearance (IAC), and impaired gas exchange (IGE). A secondary analysis with a cohort design was developed from 1128 records obtained during the hospital stay of 136 children with acute respiratory infection. Groups of defining characteristics with greater differentiation capacity were identified by multiple correspondence analyses. The results showed that the defining characteristics that better differentiate the studied diagnoses are agitation, irritability and diaphoresis for IGE; dyspnea, use of accessory muscles to breathe, orthopnea, and abnormal breathing pattern for IBP and excessive sputum, absence of cough, difficulty verbalizing, nasal flaring, and adventitious breath sounds for IAC. Twelve defining characteristics that can assist clinicians to differentiate the three main respiratory nursing diagnoses among children with acute respiratory infection were identified in this study.

Ineffective breathing pattern in cardiac postoperative patients: Diagnostic accuracy study.

PURPOSE: The aim of this study was to analyze the accuracy of the defining characteristics of ineffective breathing pattern (IBP) in postoperative cardiac patients. METHODS: A diagnostic accuracy study was performed with 98 patients. Measures of sensitivity, specificity, predictive values, likelihood ratios, diagnostic odds ratio, and area under the ROC curve were calculated. RESULTS: IBP was present in 23.5% of the patients. Alterations in depth of breathing (sensitivity 96%, negative likelihood ratio 0.11%) and pursed-lip breathing (sensitivity 99%, negative likelihood ratio 0.07%) were the most sensitive defining characteristics for IBP, while altered chest excursion (specificity 97%, positive likelihood ratio 11.41%) and prolonged expiration phase (specificity 99%, positive likelihood ratio 42.39%) were the most specific. CONCLUSION: Some clinical indicators were more related to the presence or absence of IBP than others. Knowledge of such measures can help nurses to assess patients more accurately.

Ineffective breathing pattern in children and adolescents with congenital heart disease: accuracy of defining characteristics.

AIMS AND OBJECTIVES: The purpose of this study was to assess the prevalence of ineffective breathing pattern and the accuracy of its defining characteristics, among children and adolescents with congenital heart disease. BACKGROUND: The NANDA International nursing diagnosis, ineffective breathing pattern, has been noted to have high prevalence in different clinical contexts and age groups. Despite that, nurses continue to report difficulties in confirming this diagnosis. The lack of data regarding the sensitivity, specificity and predictive values of the defining characteristics contribute to decreased certainty in diagnosing ineffective breathing pattern. DESIGN: A diagnostic accuracy study. METHODS: This study of diagnostic accuracy was conducted with 61 children and adolescents with congenital heart disease. Two nurses were trained by the primary investigator on use of defining characteristics in the diagnostic process for ineffective breathing pattern. RESULTS: Ineffective breathing pattern was present in 26·2% of the children and adolescents sampled. When analysing the defining characteristics, alterations in depth of breathing, showed high values of sensitivity and specificity. In addition, orthopnoea, tachypnoea and use of accessory muscles to breathe, showed high values of specificity; dyspnoea showed high values of sensitivity. Finally, assumption of three-point position, bradypnoea and increased anterior-posterior diameter were not found to be statistically significant for this sample population. CONCLUSION: Five defining characteristics of ineffective breathing pattern presented measures of accuracy with statistically significant values in children with congenital heart disease. RELEVANCE TO CLINICAL PRACTICE: The findings can help nurses during the diagnostic process, as they identify which defining characteristics can be used to confirm or rule out the probability of occurrence of the diagnosis.

[Clinical indicators of "ineffective breathing pattern" in children with congenital heart disease]. / Indicatori clinici di "Modello di respirazione inefficace" nei bambini con cardiopatie congenite.

UNLABELLED: Clinical indicators of ineffective breathing pattern in children with congenital heart disease. OBJECTIVES: To analyze the accuracy of clinical predictors of nursing diagnosis "Ineffective breathing pattern in children with congenital heart disease". METHOD: 1:1 case-control study with 30 children with congenital heart disease. Fifteen children with the nursing diagnosis "Ineffective breathing pattern" (cases) were compared with other 15 without this diagnosis (controls). A total of 15 clinical indicators were analyzed for their sensibility, specificity, predictive values, likelihood ratios and area under the ROC curve. RESULTS: Four indicators showed an area under the ROC curve > 70%: chest x-ray findings (0.750), adventitious breath sounds (0.737), coughing (0.710) and asymmetric chest expansion (0.702). The indicators of the chest x-ray findings and adventitious breath sounds had a better overall performance for the identification of ineffective breathing pattern. DISCUSSION: These findings suggest that both indicators can be useful for inference of ineffective breathing pattern. Moreover, the presence of the diagnosis was associated with a greater likelihood of the presence of cough, and its absence with an increased probability of the absence of asymmetric chest expansion and percussive sounds. CONCLUSIONS: The comparison among populations with different diseases and carriers of the same nursing diagnosis shows that the predictive ability of clinical indicators can be influenced.

Hyperinflammation in COVID-19 Obese Patients Treated With Tocilizumab: A Successful Case Series.

The cytokine storm syndrome has been suggested as a mechanism in the pathophysiology of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2; COVID-19 [coronavirus disease 2019]) infection. Drugs such as tocilizumab, an interleukin-6 antagonist, have shown good results in other scenarios of hyperinflammatory state and might also be effective in COVID-19 disease. However, the best dosing regimen and the timing of infusion is currently unknown, specifically in obese patients. We report the first cases of tocilizumab administration in obese patients during the first days of COVID-19 worsening hypoxemia. This infusion was not adjusted by weight, following the manufacturer maximal dose limit. We kept a strict monitoring for possible infections, prior and during the treatment. All patients showed good improvements on chest-computed tomography images and oxygenation and were discharged from hospital shortly after, without complications or intubation. This case series highlights that tocilizumab seems to be effective to treat hyperinflammation of critical COVID-19 obese patients, even when the infusion of the ideal dose is not feasible to be administered. It also shows the importance of early timing in the decision to treat and the relevance of infections exclusion prior to the induction of immunosuppression by tocilizumab.

RESULTS: Thirty two indicators presented item-objective congruence higher than 0.80. The content validity index higher than 0.80 was identified in at least 16 indicators for each criterion. CONCLUSION: Implementation of these concepts is helpful but they need to be kept under review.

Prognostic indicators of short-term survival of ineffective airway clearance in children with acute respiratory infection: a longitudinal study.

Background: Studies that establish the indicators of clinical status deterioration of Ineffective airway clearance remain scarce. Prognostic studies provide data for nurses identify clinical indicators that suggest a higher chance of early development of a nursing diagnosis. Objective: To identify the prognostic indicators of short-term survival of ineffective airway clearance (IAC) in children with acute respiratory infection (ARI). Design: A prospective open cohort study. Methods: This study was with a group of 136 children with acute respiratory infection who were followed for a minimum of six and a maximum of ten consecutive days. Children who had not completed six days of monitoring or who were carriers of diseases that would alter the specific symptoms of respiratory infection were excluded. The survival rate of ineffective airway clearance was calculated using Nelson-Aalen's method. A Cox regression model was used to analyze the influence of clinical indicators on survival time of this diagnosis. Results: The diagnosis survival rate was extremely low (only 0.4% on the 5th day of follow-up). The greatest reduction in survival rate was observed in the first 48 h (survival rate = 2.5%). Four defining characteristics associated with a worse prognosis of IAC among children with ARI: ineffective cough (RR = 5.86; 95% CI: 3.53-9.72), absence of cough (RR = 2.92; 95% CI: 1.68-5.08), adventitious breath sounds (RR = 2.47; 95% CI: 2.01-3.03), and diminished breath sounds (RR = 1.23; 95% CI: 1.05-1.45). Conclusion: Four clinical indicators showed a strong relationship with an increased risk of worsening clinical status associated with this nursing diagnosis. Impact statement: Clinical deterioration related to ineffective airway clearance among children with acute respiratory infection is fast and requires particular attention from nurses.

Impaired Gas Exchange: Prognostic Clinical Indicators of Short-Term Survival in Children with Acute Respiratory Infection.

PURPOSE: To establish prognostic indicators of survival for impaired gas exchange (IGE) (00030). METHODS: Secondary analysis of data from an open prospective cohort developed with a group of 136 children with acute respiratory infection (ARI). FINDINGS: On Day 1, IGE (00030) was present in 42.6% of the sample. New cases arose until the last day of evaluation. With regards to defining characteristics, only hypoxemia and abnormal skin color were associated with a higher risk of developing diagnosis. CONCLUSIONS: Children with ARI who exhibit hypoxemia and abnormal skin color had a worse prognosis for IGE (00030). IMPLICATIONS FOR NURSE PRACTICE: Nurses can use the research findings as a predictive marker of the evolution of the patient's health status.

CONCLUSION: Ineffective coughing and adventitious breath sounds had better predictive capacity for Ineffective airway clearance in the sample.

Analysis of ineffective breathing pattern and impaired spontaneous ventilation of adults with oxygen therapy.

OBJECTIVE: to analyze the manifestation of the defining characteristics of the nursing diagnoses of ineffective breathing pattern and impaired spontaneous ventilation, of the NANDA International and the defining characteristics identified in the literature for the concept of "ventilation" in adult patients hospitalized in an intensive care unit with use of oxygen therapy. METHOD: clinical diagnostic validation study, conducted with 626 patients in intensive care using oxygen therapy, in three different modalities. Multiple correspondence analysis was used to verify the discriminative capacity of the defining characteristics and latent class analysis to determine the diagnostic accuracy of them, based on the severity level defined by the ventilatory mode used. RESULTS: in the multiple correspondence analysis, it was demonstrated that the majority of the defining characteristics presented low discriminative capacity and low percentage of explained variance for the two dimensions (diagnoses). Latent class models, separately adjusted for the two diagnoses, presented a worse fit, with sharing of some defining characteristics. Models adjusted by level of severity (ventilation mode) presented better fit and structure of the component defining characteristics. CONCLUSION: clinical evidence obtained in the present study seems to demonstrate that the set of defining characteristics of the two nursing diagnoses studied fit better in a single construct.

Clinical indicators of ineffective airway clearance in children with acute respiratory infection.

The identification of clinical indicators with good predictive ability allows the nurse to minimize the existing variability in clinical situations presented by the patient and to accurately identify the nursing diagnosis, which represents the true clinical condition. The purpose of this study was to analyze the accuracy of NANDA-I clinical indicators of the nursing diagnosis ineffective airway clearance (IAC) in children with acute respiratory infection. This was a prospective cohort study conducted with a group of 136 children and followed for a period of time ranging from 6 to 10 consecutive days. For data analysis, the measures of accuracy were calculated for clinical indicators, which presented statistical significance in a generalized estimated equation model. IAC was present in 91.9% of children in the first assessment. Adventitious breath sounds presented the best measure of accuracy. Ineffective cough presented a high value of sensitivity. Changes in respiratory rate, wide-eyed, diminished breath sounds, and difficulty vocalizing presented high positive predictive values. In conclusion, adventitious breath sounds showed the best predictive ability to diagnose IAC in children with respiratory acute infection.

Defining characteristics of the nursing diagnosis "ineffective airway clearance".

OBJECTIVE: to analyze the defining characteristics of the nursing diagnosis "ineffective airway clearance" in children with acute respiratory infection. METHOD: cross-sectional descriptive study, developed in two hospitals specialized in care for children. It was held a detailed respiratory evaluation of the child to identify the defining characteristics of the diagnosis under study. RESULTS: a total of 249 children were evaluated, 55.8% were male and the median age was 13.76 months. Ineffective airway clearance was identified in 222 children (89.2%). The following defining characteristics presented statistically significant associations: dyspnea, expectoration, orthopnea, respiratory adventitious sounds, decreased breath sounds and ineffective cough. Decreased breath sounds, ineffective cough and respiratory adventitious sounds composed the logistic regression model. CONCLUSION: the characteristics decreased breath sounds, ineffective cough and respiratory adventitious sounds have better predictive capacity for the diagnosis "ineffective airway clearance" in children with acute respiratory infection.

Impaired gas exchange: accuracy of defining characteristics in children with acute respiratory infection.

OBJECTIVE: to analyze the accuracy of the defining characteristics of the Impaired gas exchange nursing diagnosis in children with acute respiratory infection. METHOD: open prospective cohort study conducted with 136 children monitored for a consecutive period of at least six days and not more than ten days. An instrument based on the defining characteristics of the Impaired gas exchange diagnosis and on literature addressing pulmonary assessment was used to collect data. The accuracy means of all the defining characteristics under study were computed. RESULTS: the Impaired gas exchange diagnosis was present in 42.6% of the children in the first assessment. Hypoxemia was the characteristic that presented the best measures of accuracy. Abnormal breathing presented high sensitivity, while restlessness, cyanosis, and abnormal skin color showed high specificity. All the characteristics presented negative predictive values of 70% and cyanosis stood out by its high positive predictive value. CONCLUSION: hypoxemia was the defining characteristic that presented the best predictive ability to determine Impaired gas exchange. Studies of this nature enable nurses to minimize variability in clinical situations presented by the patient and to identify more precisely the nursing diagnosis that represents the patient's true clinical condition.

[The adequacy of the defining characteristics of the diagnostics "impaired gas exange" and spontaneous ventilation" in asmathic children]. / Adecuación de las características definitorias en los diagnósticos de deterioro del intercambio de gases y de la ventilación espontánea en niños asmáticos.

OBJECTIVE: To determine the diagnostic accuracy measures of defining characteristics of respiratory nursing diagnoses "impaired gas exchange" and "impaired spontaneous ventilation" in asmathics children in emergency department. METHODS: Observational, descriptive transversal study developed between April and September 2013 in a hospital in northeastern Brazil with a sample of 205 children. Diagnoses were established by nurses trained experts in this field. Measures of sensitivity, specificity, positive and negative value prediction right positive and negative likelihood ratio and diagnostic odds for the defining characteristics identified were calculated. RESULTS: 28.8% of the evaluated children had "impaired gas exchange". Dyspnea, abnormal breathing, tachycardia and hypoxemia had higher frequencies. Hypoxemia presented as clinical feature high sensitivity and specificity. 5.9% of the evaluated children had "impaired spontaneous ventilation" and their most frequent defining characteristics were dyspnea, increased heart rate and decreased SaO2. The increasing use of accessory muscles to breathe presented the best measures of validity for this diagnosis. CONCLUSION: The hypoxemia and increased use of accessory muscles presented the best measures of the validity respectively to "deterioration in gas exchange" and "impairment of spontaneous ventilation". These characteristics is necessary to provide for adequate definition and use of diagnostics in clinical practice.
