Meta-Analysis Review
BACKGROUND
Tracheal intubation is a commonly performed procedure that can be associated with complications and result in patient harm. Videolaryngoscopy (VL) may decrease this risk as compared with Macintosh direct laryngoscopy (DL). This review evaluates the risk and benefit profile of VL compared with DL in adults.
METHODS
We searched MEDLINE, Embase, CENTRAL, and Web of Science on February 27, 2021. We included RCTs comparing VL with DL in patients undergoing tracheal intubation in any setting. We separately compared outcomes according to VL design: Macintosh-style, hyperangulated, and channelled.
RESULTS
A total of 222 RCTs (with 26 149 participants) were included. Most studies had unclear risk of bias in at least one domain, and all were at high risk of performance and detection bias. We found that videolaryngoscopes of any design likely reduce rates of failed intubation (Macintosh-style: risk ratio [RR]=0.41; 95% confidence interval [CI], 0.26-0.65; hyperangulated: RR=0.51; 95% CI, 0.34-0.76; channelled: RR=0.43, 95% CI, 0.30-0.61; moderate-certainty evidence) with increased rates of successful intubation on first attempt and better glottic views across patient groups and settings. Hyperangulated designs are likely favourable in terms of reducing the rate of oesophageal intubation, and result in improved rates of successful intubation in individuals presenting with difficult airway features (P=0.03). We also present other patient-oriented outcomes.
CONCLUSIONS
In this systematic review and meta-analysis of trials of adults undergoing tracheal intubation, VL was associated with fewer failed attempts and complications such as hypoxaemia, whereas glottic views were improved.

Meta-Analysis Review
Benefits and harms of normal saline instillation before endotracheal suctioning in mechanically ventilated adult patients in intensive care units: A systematic literature review and meta-analysis.
OBJECTIVES
This systematic review aimed to identify the effects of normal saline instillation before endotracheal suctioning on clinical outcomes in critically ill patients on a mechanical ventilator.
RESEARCH METHODOLOGY
This review was based on the guidelines of the National Evidence-based Healthcare Collaborating Agency in Korea and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist. Six electronic databases were searched for relevant literature. Other sources were also searched, including the reference lists of identified reports and previous systematic reviews. After the initial literature search, a two-step retrieval process was performed to select eligible studies. Then, data were collected using a newly developed form, and the risk of bias was assessed using the checklists of the Joanna Briggs Institute. Data were analyzed using both narrative syntheses and meta-analyses.
RESULTS
In total, 16 studies: 13 randomized controlled trials and three quasi-experimental studies, were included. From the narrative syntheses, instilling normal saline before endotracheal suctioning was associated with a decrease in oxygen saturation, prolonged time for oxygen saturation to recover to baseline, decreased arterial pH, increased secretion amount, reduced incidence of ventilator-associated pneumonia, increased heart rate, and increased systolic blood pressure. Meta-analyses showed a significant difference in heart rate at five minutes after suctioning but no significant differences in oxygen saturation at two and five minutes after suctioning and heart rate at two minutes after suctioning.
CONCLUSION
This systematic review indicated that instilling normal saline before performing endotracheal suctioning has more harmful effects than benefits.
IMPLICATIONS FOR CLINICAL PRACTICE
As recommended in the current guidelines, it is necessary to refrain from routine normal saline instillation before endotracheal suctioning.

Meta-Analysis
BACKGROUND
Despite several clinical index tests that are currently applied for airway assessment, unpredicted difficult laryngoscopy may still represent a serious problem in anesthesia practice. The aim of this systematic review and meta-analysis was to evaluate whether preoperative airway ultrasound can predict difficult direct laryngoscopy in adult patients undergoing elective surgery under general anesthesia.
METHODS
We searched the Medline, Scopus, and Web of Science databases from their inception to December 2020. The population of interest included adults who required tracheal intubation for elective surgery under general anesthesia without clear anatomical abnormalities suggesting difficult laryngoscopy. A bivariate model has been used to assess the accuracy of each ultrasound index test to predict difficult direct laryngoscopy.
RESULTS
Fifteen studies have been considered for quantitative analysis of summary receiver operating characteristic (SROC). The sensitivity for distance from skin to epiglottis (DSE), distance from skin to hyoid bone (DSHB), and distance from skin to vocal cords (DSVC) was 0.82 (0.74-0.87), 0.71 (0.58-0.82), and 0.75 (0.62-0.84), respectively. The specificity for DSE, DSHB, and DSVC was 0.79 (0.70-0.87), 0.71 (0.57-0.82), and 0.72 (0.45-0.89), respectively. The area under the curve (AUC) for DSE, DSHB, DSVC, and ratio between the depth of the pre-epiglottic space and the distance from the epiglottis to the vocal cords (Pre-E/E-VC) was 0.87 (0.84-0.90), 0.77 (0.73-0.81), 0.78 (0.74-0.81), and 0.71 (0.67-0.75), respectively. Patients with difficult direct laryngoscopy have higher DSE, DSVC, and DSHB values than patients with easy laryngoscopy, with a mean difference of 0.38 cm (95% confidence interval [CI], 0.17-0.58 cm; P = .0004), 0.18 cm (95% CI, 0.01-0.35 cm; P = .04), and 0.23 cm (95% CI, 0.08-0.39 cm; P = .004), respectively.
CONCLUSIONS
Our study demonstrates that airway ultrasound index tests are significantly different between patients with easy versus difficult direct laryngoscopy, and the DSE is the most studied index test in literature to predict difficult direct laryngoscopy. However, it is not currently possible to reach a definitive conclusion. Further studies are needed with better standardization of ultrasound assessment to limit all possible sources of heterogeneity.

Meta-Analysis Review
PURPOSE
Compare outcomes of adult patients admitted to ICU- length of ICU stay, length of mechanical ventilation (MV), and time until extubation- according to the use of propofol versus midazolam.
METHODS
We searched MEDLINE, EMBASE, LILACS, and Cochrane databases to retrieve RCTs that compared propofol and midazolam used as sedatives in adult ICU patients. We applied a random-effects, meta-analytic model in all calculations. We applied the Cochrane collaboration tool and GRADE. We separated patients into two groups: acute surgical patients (hospitalization up to 24 h) and critically-ill patients (hospitalization over 24 h and whose articles mostly mix surgical, medical and trauma patients).
RESULTS
Globally, propofol was associated with a reduced MV time of 4.46 h (MD: -4.46 [95% CI -7.51 to -1.42] p = 0.004, I2 = 63%, 6 studies) and extubation time of 7.95 h (MD: -7.95 [95% CI -9.86 to -6.03] p < 0.00001, I2 = 98%, 16 studies). Acute surgical patients sedation with propofol compared to midazolam was associated with a reduced ICU stay of 5.07 h (MD: -5.07 [95% CI -8.68 to -1.45] p = 0.006, I2 = 41%, 5 studies), MV time of 4.28 h (MD: -4.28; [95% CI -4.62 to -3.94] p < 0.0001, I2 = 0%, 3 studies), extubation time of 1.92 h (MD: -1.92; [95% CI -2.71 to -1.13] p = 0.00001, I2 = 89%, 9 studies). In critically-ill patients sedation with propofol compared to midazolam was associated with a reduced extubation time of 32.68 h (MD: -32.68 [95% CI -48.37 to -16.98] p = 0.0001, I2 = 97%, 9 studies). GRADE was very low for all outcomes.
CONCLUSIONS
Sedation with propofol compared to midazolam is associated with improved clinical outcomes in ICU, with reduced ICU stay MV time and extubation time in acute surgical patients and reduced extubation time in critically-ill patients.

Meta-Analysis
Efficacy and safety of adjunctive corticosteroids in the treatment of severe community-acquired pneumonia: a systematic review and meta-analysis of randomized controlled trials.
BACKGROUND
This systematic review and meta-analysis aimed to investigate the clinical efficacy and safety of systemic corticosteroids in the treatment of patients with severe community-acquired pneumonia (sCAP).
METHODS
A comprehensive search was conducted using the Medline, Embase, ClinicalTrials.gov, and Scopus databases for articles published until April 24, 2023. Only randomized controlled trials (RCTs) that assessed the clinical efficacy and safety of adjunctive corticosteroids for treating sCAP were included. The primary outcome was the 30-day all-cause mortality.
RESULTS
A total of severe RCTs involving 1689 patients were included in this study. Overall, the study group had a lower mortality rate at day 30 than the control group (risk ratio [RR], 0.61; 95% CI 0.44 to 0.85; p < 0.01) with low heterogeneity (I = 0%, p = 0.42). Compared to the control group, the study group had a lower risk of the requirement of mechanical ventilation (RR 0.57; 95% CI 0.45 to 0.73; p < 0.001), shorter length of intensive care unit (MD - 0.8; 95% CI - 1.4 to - 0.1; p = 0.02), and hospital stay (MD - 1.1; 95% CI - 2.0 to - 0.1; p = 0.04). Finally, no significant difference was observed between the study and the control groups in terms of gastrointestinal tract bleeding (RR 1.03; 95% CI 0.49 to 2.18; p = 0.93), healthcare-associated infection (RR 0.89; 95% CI 0.60 to 1.32; p = 0.56), and acute kidney injury (RR 0.68; 95% CI 0.21 to 2.26; p = 0.53).
CONCLUSIONS
In patients with sCAP, adjunctive corticosteroids can provide survival benefits and improve clinical outcomes without increasing adverse events. However, because the pooled evidence remains inconclusive, further studies are required.

Meta-Analysis
BACKGROUND
Respiratory distress, particularly respiratory distress syndrome (RDS), is the single most important cause of morbidity and mortality in preterm infants. In infants with progressive respiratory insufficiency, intermittent positive pressure ventilation (IPPV) with surfactant has been the usual treatment, but it is invasive, potentially resulting in airway and lung injury. Continuous positive airway pressure (CPAP) has been used for the prevention and treatment of respiratory distress, as well as for the prevention of apnoea, and in weaning from IPPV. Its use in the treatment of RDS might reduce the need for IPPV and its sequelae.
OBJECTIVES
To determine the effect of continuous distending pressure in the form of CPAP on the need for IPPV and associated morbidity in spontaneously breathing preterm infants with respiratory distress.
SEARCH METHODS
We used the standard strategy of Cochrane Neonatal to search CENTRAL (2020, Issue 6); Ovid MEDLINE and Epub Ahead of Print, In-Process & Other Non-Indexed Citations, Daily and Versions; and CINAHL on 30 June 2020. We also searched clinical trials databases and the reference lists of retrieved articles for randomised controlled trials and quasi-randomised trials.
SELECTION CRITERIA
All randomised or quasi-randomised trials of preterm infants with respiratory distress were eligible. Interventions were CPAP by mask, nasal prong, nasopharyngeal tube or endotracheal tube, compared with spontaneous breathing with supplemental oxygen as necessary.
DATA COLLECTION AND ANALYSIS
We used standard methods of Cochrane and its Neonatal Review Group, including independent assessment of risk of bias and extraction of data by two review authors. We used the GRADE approach to assess the certainty of evidence. Subgroup analyses were planned on the basis of birth weight (greater than or less than 1000 g or 1500 g), gestational age (groups divided at about 28 weeks and 32 weeks), timing of application (early versus late in the course of respiratory distress), pressure applied (high versus low) and trial setting (tertiary compared with non-tertiary hospitals; high income compared with low income) MAIN RESULTS: We included five studies involving 322 infants; two studies used face mask CPAP, two studies used nasal CPAP and one study used endotracheal CPAP and continuing negative pressure for a small number of less ill babies. For this update, we included one new trial. CPAP was associated with lower risk of treatment failure (death or use of assisted ventilation) (typical risk ratio (RR) 0.64, 95% confidence interval (CI) 0.50 to 0.82; typical risk difference (RD) -0.19, 95% CI -0.28 to -0.09; number needed to treat for an additional beneficial outcome (NNTB) 6, 95% CI 4 to 11; I = 50%; 5 studies, 322 infants; very low-certainty evidence), lower use of ventilatory assistance (typical RR 0.72, 95% CI 0.54 to 0.96; typical RD -0.13, 95% CI -0.25 to -0.02; NNTB 8, 95% CI 4 to 50; I = 55%; very low-certainty evidence) and lower overall mortality (typical RR 0.53, 95% CI 0.34 to 0.83; typical RD -0.11, 95% CI -0.18 to -0.04; NNTB 9, 95% CI 2 to 13; I = 0%; 5 studies, 322 infants; moderate-certainty evidence). CPAP was associated with increased risk of pneumothorax (typical RR 2.48, 95% CI 1.16 to 5.30; typical RD 0.09, 95% CI 0.02 to 0.16; number needed to treat for an additional harmful outcome (NNTH) 11, 95% CI 7 to 50; I = 0%; 4 studies, 274 infants; low-certainty evidence). There was no evidence of a difference in bronchopulmonary dysplasia, defined as oxygen dependency at 28 days (RR 1.04, 95% CI 0.35 to 3.13; I = 0%; 2 studies, 209 infants; very low-certainty evidence). The trials did not report use of surfactant, intraventricular haemorrhage, retinopathy of prematurity, necrotising enterocolitis and neurodevelopment outcomes in childhood.
AUTHORS' CONCLUSIONS
In preterm infants with respiratory distress, the application of CPAP is associated with reduced respiratory failure, use of mechanical ventilation and mortality and an increased rate of pneumothorax compared to spontaneous breathing with supplemental oxygen as necessary. Three out of five of these trials were conducted in the 1970s. Therefore, the applicability of these results to current practice is unclear. Further studies in resource-poor settings should be considered and research to determine the most appropriate pressure level needs to be considered.

Meta-Analysis Review
Effectiveness of interventions to prevent pressure injury in adults admitted to intensive care settings: A systematic review and meta-analysis of randomised controlled trials.
OBJECTIVE
The aim of the study was to investigate the effectiveness of interventions to prevent pressure injury in adults admitted to intensive care settings.
REVIEW METHOD USED
This is a systematic review and meta-analysis of randomised controlled trials.
DATA SOURCES
Five databases (CINAHL, MEDLINE, Scopus, Web of Science, and Embase) were searched in mid-2019. Searches were updated (in April 2020) to year end 2019.
REVIEW METHODS
From an overarching systematic review and meta-analysis examining the effectiveness of pressure injury preventative interventions in adults admitted to acute hospital settings, trials conducted in intensive care were separated for an intensive care-specific synthesis. Two reviewers, with a third as an arbitrator, undertook study selection, data extraction, and risk-of-bias assessment. Included trials were grouped by intervention type for narrative synthesis and for random-effects meta-analysis using intention-to-treat data where appropriate.
RESULTS
Overall, 26 trials were included. Ten intervention types were found (support surfaces, prophylactic dressings, positioning, topical preparations, continence management, endotracheal tube securement, heel protection devices, medication, noninvasive ventilation masks, and bundled interventions). All trials, except one, were at high or unclear risk of bias. Four intervention types (endotracheal tube securement, heel protection devices, medication, and noninvasive ventilation masks) comprised single trials. Support surface trials were limited to type (active, reactive, seating, other). Meta-analysis was undertaken for reactive surfaces, but the intervention effect was not significant (risk ratio = 0.24, p = 0.12, I = 51%). Meta-analyses demonstrated the effectiveness of sacral (risk ratio = 0.22, p < 0.001, I = 0%) and heel (risk ratio = 0.31, p = 0.02; I = 0%) prophylactic dressings for pressure injury prevention.
CONCLUSIONS
Only prophylactic sacral and heel dressings demonstrated effectiveness in preventing pressure injury in adults admitted to intensive care settings. Further intensive care-specific trials are required across all intervention types. To minimise bias, we recommend that all future trials are conducted and reported as per relevant guidelines and recommendations.

Meta-Analysis Review
BACKGROUND
Post-extubation dysphagia has been associated with adverse health outcomes. To assist service planning and process development for early identification, an understanding of the number of patients affected is required. However, significant variation exists in the reported incidence which ranges from 3% to 62%.
OBJECTIVES
The objective of this study was to (i) conduct a meta-analysis on the incidence of dysphagia after endotracheal intubation in adult critically ill patients and (ii) describe the extent of heterogeneity within peer-reviewed articles and grey literature on the incidence of dysphagia after endotracheal intubation.
DATA SOURCES
Databases CINAHL, Cochrane Library, Embase, MEDLINE, PubMed, SpeechBITE, and Google Scholar were systematically searched for studies published before October 2019.
REVIEW METHODS
Data extraction occurred in a double-blind manner for studies meeting the inclusion criteria. Risk of bias was determined using critical appraisal tools relevant to the individual study design. The overall quality of the synthesised results was described using the Grading of Recommendations Assessment, Development and Evaluation methodology. Raw data were transformed using Freeman-Tukey arcsine square root methodology. A random-effects model was utilised owing to heterogeneity between studies.
RESULTS
Of 3564 identified studies, 38 met the criteria for inclusion in the final review. A total of 5798 patient events were analysed, with 1957 dysphagic episodes identified. The combined weighted incidence of post-extubation dysphagia was 41% (95% confidence interval, 0.33-0.50). Of the patients with dysphagia, 36% aspirated silently (n = 155, 95% confidence interval, 0.22-0.50). Subgroup meta-regression analysis was unable to explain the heterogeneity across studies when accounting for the method of participant recruitment, method of dysphagia assessment, median duration of intubation, timing of dysphagia assessment, or patient population.
CONCLUSION
Dysphagia after endotracheal intubation is common and occurs in 41% of critically ill adults. Given the prevalence of dysphagia and high rates of silent aspiration in this population, further prospective research should focus on systematic and sensitive early identification methods.

PURPOSE
The purpose of this article was to determine specific skin injury prevention interventions for neonates in the NICU.
DESIGN
The design was a systematic review.
SAMPLE
PubMed, Cumulative Index of Nursing and Allied Health Literature (CINAHL), Embase, and Scopus were systematically searched to identify quantitative studies identifying skin injury preventions for neonates in the NICU.
OUTCOMES
The outcomes included skin integrity or skin condition.
RESULTS
Nineteen studies were included in the review. Twelve studies included a randomized design. Barriers were the main interventions for the prevention of pressure injury, medical adhesive skin injury, diaper dermatitis, and general skin condition. The types of barriers included hydrocolloids, polyurethane-based dressings, film-forming skin protectant, or emollients. Nonbarrier interventions included rotation between a mask and nasal continuous positive airway pressure (NCPAP) interfaces, utilization of prescribed guidelines to decrease pressure injuries, and use of a lower concentration of chlorhexidine gluconate as a disinfectant.

Meta-Analysis
OBJECTIVE
This study aimed to investigate the effects of different types and frequencies of physiotherapy on ventilator weaning among patients in the intensive care unit (ICU) and to identify the optimal type and frequency of intervention.
DATA SOURCES
PubMed, Cochrane Library, EMBASE, and Airiti Library.
STUDY SELECTION
Randomized controlled trials that provided information on the dosage of ICU rehabilitation and the parameters related to ventilator weaning were included.
DATA EXTRACTION AND MANAGEMENT
Treatment types were classified into conventional physical therapy, exercise-based physical therapy, neuromuscular electrical stimulation (NEMS), progressive mobility, and multi-component. The frequencies were divided into high (≥ 2 sessions/day or NEMS of > 60 minutes/day), moderate (one session/day, 3-7 days/week or NEMS of 30-60 minutes/day), and low (one session/day, < 3 days/week, or NEMS of < 30 minutes/day).
DATA SYNTHESIS
Twenty-four articles were included for systematic review and 15 out of 24 articles were analyzed in the meta-analysis. Early rehabilitation, especially the progressive mobility treatment exerted an optimal effect in reducing the ventilator duration in patients in the ICU (standardized mean difference [SMD] = 0.91; 95% confidence interval [CI] = 0.23-1.58; P < 0.01). Regarding the treatment frequency, the high-frequency intervention did not result in a favorable effect on ventilator duration compared with the moderate frequency of treatment (SMD = 0.75; 95% CI = -1.13-2.64; P = 0.43).
CONCLUSION
Early rehabilitation with progressive mobility is highly recommended to decrease the ventilation duration received by patients in the ICU. Depending on clinical resources and the tolerance of patients, the frequency of interventions should reach moderate-to-high frequency, that is, at least one session per day and 3 days a week.
