RESUMO

OBJECTIVES: Despite phototherapy (in the form of photodynamic therapy (PDT)-mediated oxidative stress) being utilized in the management of oral potentially malignant disorders (OPMDs), the evidence of certainty remains unclear. Hence, this systematic review and meta-analysis (PROSPERO # CRD42021218748) is aimed to evaluate the clinical efficacy of PDT-induced oxidative stress in OPMDs METHODS: PubMed, Embase, Web of Science, Scopus, and Cochrane Library databases were searched without restriction of language or year of publication. In addition, gray literature was searched and a manual search was performed. Two independent reviewers screened all the studies, assessing data extraction, risk of bias and certainty of evidence. A narrative synthesis was carried out. For the meta-analysis, random effects were considered to determine the prevalence of a total and a partial remission (PR) of oral potentially malignant disorders (OPMDs). The certainty of evidence was explored using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach. RESULTS: Twenty-three studies were included in the qualitative and quantitative syntheses. A total of 880 patients were included (564 males; 218 females) with an age range between 24 and 89-years-old. The results showed the prevalence of the total and partial remissions respectively for the following OPMLs: actinic cheilitis (AC): 69.9% and 2.4%; oral leukoplakia (OL): 44% and 36.9%; oral verrucous hyperplasia (OVH): 98.5%; oral erythroleukoplakia (OEL): 92.1% and 7.9%. The prevalence of no remission of OL was 18.8%. CONCLUSIONS: PDT demonstrated significant results in clinical remission of OPMDs and most of the eligible studies have shown a total or a partial remission of the included lesions, but at a low or a very low certainty of evidence. Hence, further clinical studies with robust methodology are warranted to offer further validated data. Also, further evidence is required to understand further the mechanism of PDT-induced oxidative stress.

RESUMO

AIM: Studies assessing the association between admission time to paediatric intensive care unit (PICU) and mortality are sparse with conflicting results. We aimed to evaluate the impact of time of admission on PICU mortality within 48 h after admission. METHODS: This was a single-centre prospective cohort. We collected data from all consecutive children aged 1 month to 16 years over 10 years. RESULTS: We included a total of 1368 admissions, with a PICU mortality of 6.6%. Compared with daytime admissions, the overall mortality rate (5.3% vs. 8.5%, P = 0.026) and the mortality within 48 h after admission were higher for those admitted during night-time (2% vs. 4.2%, P = 0.021). There were no differences between mortality rates and the day of admission (weekend admissions vs. weekday admissions). The adjusted odds of death within 48 h after admission was 2.5 (95% confidence interval = 1.22-5.24, P = 0.012) for patients admitted at night-time. A secondary analysis assessing trends in mortality rates during admission showed that the last 5 years of study were more responsible for the chances of death within 48 h (odds ratio = 7.6, 95% confidence interval = 1.91-30.17, P = 0.0039). CONCLUSION: Admission to the PICU during night shifts was strongly associated with death compared to daytime admissions. A time analysis of the moment of admission is necessary as a metric of quality of care to identify the interruption or improvement in the continuity of care. Further studies are needed to assess the modified contributing factors.

RESUMO

We aimed to evaluate the effects of two brands of bST (bovine somatoropin) on productive performance and on Minas Padrão cheese yield. Fifteen Girolando cows with more than 60 days of lactation were used. The animals were distributed in a randomized block design, according to days in milk, with three treatments (somatotropin A, somatotropin B, and control). The animals received a balanced diet with commercial concentrate and corn silage as roughage. It was measured milk yield and composition, dry matter intake, body condition score (BCS), and feeding behavior; it was compared by Tukey at 5.0% of significance level. Physical-chemical composition of Minas Padrão cheese was obtained from the different treatments, was also measured, being evaluated in a completely randomized design, and compared by Tukey at 1.0% of significance level. The dry matter intake per body weight lower in control treatment (p < 0.05) was equal to 2.85, somatotropin A was equal to 3.17, and somatotropin B was equal to 3.17. Animals that received bST showed higher milk production (p < 0.05), with control being 17.56 kg/day, somatotropin A 21.12 kg/day, and somatotropin B 20.69 kg/day. The physical-chemical composition of milk showed significant differences (p < 0.05) for the fat, protein, and dry extract contents. The somatotropin applications also influenced the BCS (p < 0.05) and the feeding behavior in time for total intake, time spent with rumination, and idleness. The application of bST increased milk yield and technical and economic yields of Minas Padrão cheese did not show significant differences between treatments.

RESUMO

PURPOSE: Although several studies assess unplanned extubation (UE) in children, few have addressed determinants of UE and factors associated with reintubation in a case-controlled manner. We aimed to identify the risk factors and outcomes associated with UE in a pediatric intensive care unit. METHODS: Cases of UE were randomly matched with control patients at a ratio of 1:4 for age, severity of illness, and admission diagnosis. For cases and controls, we also collected data associated with UE events, reintubation, and outcomes. RESULTS: We analyzed 94 UE patients (0.75 UE per 100 intubation days) and found no differences in demographics between the 2 groups. Logistic regression revealed that patient agitation (odds ratio [OR]: 2.44; 95% confidence interval [CI]: 1.28-4.65), continuous sedation infusion (OR: 3.27; 95% CI: 1.70-6.29), night shifts (OR: 9.16; 95% CI: 4.25-19.72), in-charge nurse experience <2 years (OR: 2.38; 95% CI: 1.13-4.99), and oxygenation index (OI) >5 (OR: 76.9; 95% CI: 16.79-352.47) were associated with UE. Risk factors for reintubation after UE included prior level of sedation (COMFORT score < 27; OR: 7.93; 95% CI: 2.30-27.29), copious secretion (OR: 11.88; 95% CI: 2.20-64.05), and OI > 5 (OR: 9.32; 95% CI: 2.45-35.48). CONCLUSIONS: This case-control study showed that both patient- and nurse-associated risk factors were related to UE. Risk factors associated with reintubation included lower levels of consciousness, copious secretions, and higher OI. Further evidence-based studies, including a larger sample size, are warranted to identify predisposing factors in UEs.

RESUMO

OBJECTIVES: Tracheal suctioning is a routine procedure in mechanically ventilated children, however, in severe head-injured patients it can result in potential deleterious increase in intracranial pressure. We aimed to assess the effect of tracheal lidocaine administration on intracranial pressure during tracheal suctioning. DESIGN: Prospective randomized controlled crossover study. SETTING: PICU of a tertiary hospital. PATIENTS: Eleven patients with severe head trauma (Glasgow Coma Scale score 4-8) INTERVENTIONS:: Lidocaine (1.5 mg/kg) or saline solution was endotracheally instilled before a standardized tracheal suctioning maneuver. Each patient received both treatments in a crossover design. Cerebral hemodynamic and systemic and ventilatory effects were assessed at four time points: in baseline (T0), within 2 minutes (T1), 5 minutes (T2), and 15 minutes after tracheal instillation (T3). The 2-minute time interval around tracheal suctioning was used to assess each treatment efficacy MEASUREMENTS AND MAIN RESULTS:: The time course of intracranial pressure was different throughout the study in both treatment groups, with a significant increase of intracranial pressure from 14.82 ± 3.48 to 23.27 ± 9.06 with lidocaine (p = 0.003) and from 14.73 ± 2.41 to 30.45 ± 13.14 with saline (p = 0.02). The mean variation in intracranial pressure immediately after tracheal suctioning was smaller with lidocaine instillation than saline (8.45 vs 15.72 mm Hg; p = 0.006). Patients treated with lidocaine returned to baseline intracranial pressure value at 5 minutes after tracheal suctioning whereas those receiving saline solution returned to baseline intracranial pressure value at 15 minutes. Although patients treated with lidocaine had no significant hemodynamic changes, patients receiving saline solution experienced a higher mean value of mean arterial pressure (99.36 vs 81.73 mm Hg; p = 0.004) at T1. CONCLUSIONS: This preliminary study showed that tracheal lidocaine instillation can attenuate increase in intracranial pressure induced by tracheal suctioning and favor a faster return to the intracranial pressure baseline levels without significant hemodynamic and ventilatory changes.

RESUMO

PURPOSE: Reintubation following unplanned extubation (UE) is often required and associated with increased morbidity; however, knowledge of risk factors leading to reintubation and subsequent outcomes in children is still lacking. We sought to determine the incidence, risk factors, and outcomes related to reintubation after UEs. METHODS: All mechanically ventilated children were prospectively tracked for UEs over a 7-year period in a pediatric intensive care unit. For each UE event, data associated with reintubation within 24 hours and outcomes were collected. RESULTS: Of 757 intubated patients, 87 UE occurred out of 11 335 intubation days (0.76 UE/100 intubation days), with 57 (65%) requiring reintubation. Most of the UEs that did not require reintubation were already weaning ventilator settings prior to UE (73%). Univariate analysis showed that younger children (<1 year) required reintubation more frequently after an UE. Patients experiencing UE during weaning experienced significantly fewer reintubations, whereas 90% of patients with full mechanical ventilation support required reintubation. Logistic regression revealed that requirement of full ventilator support (odds ratio: 37.5) and a COMFORT score <26 (odds ratio: 5.5) were associated with UE failure. There were no differences between reintubated and nonreintubated patients regarding the length of hospital stay, ventilator-associated pneumonia rate, need for tracheostomy, and mortality. Cardiovascular and respiratory complications were seen in 33% of the reintubations. CONCLUSION: The rate of reintubation is high in children experiencing UE. Requirement of full ventilator support and a COMFORT score <26 are associated with reintubation. Prospective research is required to better understand the reintubation decisions and needs.

RESUMO

OBJECTIVES: Postextubation dysphagia is common and associated with worse outcomes in the PICU. Although there has been an increased participation of speech-language pathologists in its treatment, there is limited evidence to support speech-language pathologists as core PICU team member. We aimed to assess the impact of speech-language pathologists interventions on the treatment of postextubation dysphagia. DESIGN: A quasi-experimental prospective study. In the historical group (controls), patients received a standard care management for dysphagia whereas the intervention group was routinely treated by speech-language pathologists. SETTING: PICU of a tertiary hospital. PATIENTS: Children who were endotracheally intubated for a period greater than 24 hours with greater oral intake limitation as defined by a Functional Oral Intake Scale less than or equal to 3. INTERVENTION: Routine speech-language pathologist assessment. MEASUREMENTS AND MAIN RESULTS: A total of 74 patients were enrolled to receive intervention (January 2015 to December 2016) and 41 patients to the historical group (January 2014 to December 2014). There were no differences in the demographic and clinical characteristics. The historical group had both longer time to initiate oral intake (7 vs 4 d; p = 0.0002; hazard ratio, 2.33) and to reach full oral intake compared with intervention group (9 vs 13 d; p < 0.001; hazard ratio, 2.51). A total of 32 controls (78%) and 74 intervention patients (100%) were on total oral intake at discharge (p ≤ 0.001). Three of nine control patients were feeding tube dependent at hospital discharge. Also, controls had a longer length of hospital stay (25 vs 20 d) and a higher rate of reintubation when compared with those patients of intervention group (10% vs 2%). CONCLUSIONS: Incorporating speech-language pathologists in the routine management of postextubation dysphagia can result in faster functional improvement and favorable patient outcomes. Yet, further and larger studies in pediatric dysphagia are required to support the related interventions and strategies to guide clinical practice.

RESUMO

INTRODUCTION: Contrast-induced nephropathy requiring dialysis support is rarely reported, whereas severe liver injury after contrast agent administration has not been described in children yet. CLINICAL CASE: A previously healthy 10-year-old boy with diagnosis of cerebral arteriovenous malformation underwent a cerebral angiogram study with iohexol (3 mL/kg). After 4 days, he developed vomiting and abdominal pain. Laboratory results showed abnormal liver function tests, including marked elevation of transaminases. In the next day, he evolved with oliguria and blood arterial hypertension. At this time, he presented with worsening renal function tests. Peritoneal dialysis was required for 13 days. The patient had a self-limiting course and received only supportive treatment. CLINICAL PRESENTATION: This report highlights delayed complications related to low non-ionic contrast media with a rare presentation that can be neglected or unrecognized by pediatric specialties.

RESUMO

A nanostructured immunosensor based on the liquid crystal (E)-1-decyl-4-[(4-decyloxyphenyl)diazenyl]pyridinium bromide (Br-Py) and gold nanoparticles supported by the water-soluble hybrid material 3-n-propyl-4-picolinium silsesquioxane chloride (AuNP-Si4Pic(+)Cl(-)) was built for the detection of troponin T (cTnT), a cardiac marker for acute myocardial infarction (AMI). The functionalized nanostructured surface was used to bind anti-cTnT monoclonal antibodies through electrostatic interaction. The immunosensor (ab-cTnT/AuNP-Si4Pic(+)Cl(-)/Br-Py/GCE) surface was characterized by microscopy techniques. The electrochemical behavior of the immunosensor was studied by cyclic voltammetry and electrochemical impedance spectroscopy. A calibration curve was obtained by square-wave voltammetry. The immnunosensor provided a limit of detection of 0.076 ng mL(-1) and a linear range between 0.1 and 0.9 ng mL(-1) (appropriate for AMI diagnosis).

RESUMO

AIM: Although the modified Clinical Pulmonary Infection Score (CPIS) has been used to guide treatment decisions in adults with ventilator-associated pneumonia (VAP), paediatric studies are lacking. We assessed a modified CPIS tool to define VAP resolution and identify treatment failure at an early stage. METHODS: We identified 70 mechanically ventilated children with VAP according to the Center for Disease Control criteria. Modified CPIS was initially measured at VAP onset and then three and five days afterwards. Children were defined as low risk or high risk based on a cut-off score of six. RESULTS: There were 50 high-risk and 20 low-risk patients. Culture results were positive in 64% of the high-risk patients and just 10% of the low-risk patients. Patients on adequate therapy significantly improved their CPIS scores by day three, regardless of the likelihood of VAP. A lack of score improvement demonstrated sensitivity of 100% and specificity of 83% when it came to detecting treatment failure. The area under the receiver operating curve was 0.92. CONCLUSION: Serial modified CPIS measurements showed that low-risk patients with negative cultures at day three should be considered for a short course of antibiotics. In contrast, high-risk patients with no score improvement were potentially failing their treatment.

RESUMO

BACKGROUND: The absence of pediatric surgeons in many centers results in restriction of patient access to pediatric subspecialty care. The aim of this study was to compare the outcomes of children treated for appendicitis by pediatric surgeons (PS) and by general surgeons (GS). METHODS: This was a retrospective review of the charts of all consecutive patients <16 years old who underwent appendectomy during 2 years The primary outcome measure was the overall rate of complications. Secondary outcome measures included length of hospital stay (LOS), symptom duration, time from emergency department diagnosis to surgery, and readmission rate within 30 days. RESULTS: A total of 94 patients (PS group, n = 66; GS group, n = 28) were included. PS patients were younger. For patients with complicated appendicitis, complications were significantly more prevalent in the GS group (57% vs 15%; P = 0.0001). Median LOS was not significantly different between the two groups for complicated appendicitis, but patients with non-complicated appendicitis had a significant longer LOS when treated by PS (3.74 ± 1.5 vs 2.57 ± 1.21 days; P = 0.0041). Patients in the PS group had a prolonged use of antibiotics (2 vs 4 days; P = 0.001), and longer LOS (3 vs 4 days; P = 0.0018). CONCLUSIONS: Overall complication rates were similar between PS and GS. Complications were significantly more prevalent in patients with complicated appendicitis who were treated by GS.

RESUMO

Shiga toxin-producing Escherichia coli and Shigella dysenteriae have been associated with bloody diarrhea and hemolytic uremic syndrome (HUS) in humans. However, there have been only a couple of reports describing bloody diarrhea associated with Acinetobacter spp. and there are no reports of these bacteria causing HUS in children. Here, we report the case of a nine-month-old boy with bloody diarrhea who developed non-oliguric renal failure. The clinical and laboratory findings supported the diagnosis of Acinetobacter hemolyticus infection associated with HUS. The patient responded favorably to antibiotic therapy plus conservative treatment. In conclusion, Acinetobacter infection should be considered as a plausible cause of HUS in cases where E. coli infection is not involved. The rapid transformation ability of Acinetobacter is a matter of concern.

RESUMO

BACKGROUND: Ketamine has been considered as an adjunct for children who do not reach their predefined target sedation depth. However, there is limited evidence regarding the use of ketamine as a prolonged infusion (i.e., >24 hours) in the pediatric intensive care unit (PICU). OBJECTIVE: We sought to evaluate the safety and effectiveness of continuous ketamine infusion for >24 hours in mechanically ventilated children. METHODS: We conducted a prospective cohort study in a tertiary PICU from January 2020 to December 2022. The primary outcome was the incidence of adverse events (AEs) after ketamine initiation. The secondary outcome included assessing the median proportion of time the patient spent on the Richmond Agitation-Sedation Scale (RASS) goal after ketamine infusion. Patients were also divided into two groups based on the sedative regimen, ketamine-based or non-ketamine-based, to assess the incidence of delirium. RESULTS: A total of 269 patients were enrolled: 73 in the ketamine group and 196 in the non-ketamine group. The median infusion rate of ketamine was 1.4 mg/kg/h. Delirium occurred in 16 (22%) patients with ketamine and 15 (7.6%) patients without ketamine (p = 0.006). After adjusting for covariates, logistic regression showed that delirium was associated with comorbidities (odds ratio [OR] 4.2), neurodevelopmental delay (OR 0.23), fentanyl use (OR 7.35), and ketamine use (OR 4.17). Thirty-one (42%) of the patients experienced at least one AE following ketamine infusion. Other AEs likely related to ketamine were hypertension (n = 4), hypersecretion (n = 14), tachycardia (n = 6), and nystagmus (n = 2). There were no significant changes in hemodynamic variables 24 h after the initiation of ketamine. Regarding the secondary outcomes, patients were at their goal RASS level for a median of 76% (range 68-80.5%) of the time in the 24 hours before ketamine initiation, compared with 84% (range 74.5-90%) of the time during the 24 h after ketamine initiation (p < 0.001). The infusion rate of ketamine did not significantly affect concomitant analgesic and sedative infusions. The ketamine group experienced a longer duration of mechanical ventilation and a longer length of stay in the PICU and hospital than the non-ketamine group. CONCLUSION: The use of ketamine infusion in PICU patients may be associated with an increased rate of adverse events, especially delirium. High-quality studies are needed before ketamine can be broadly recommended or adopted earlier in the sedation protocol.

RESUMO

BACKGROUND: Although unplanned postoperative admission to PICUs (unplanned intensive care admission [UIA]) is uncommon, it might be associated with increased costs, morbidity, and mortality. However, detailed knowledge of risk factors and outcomes after UIA in children is still lacking. OBJECTIVES: To determine prevalence, risk factors, and outcomes of UIA patients compared with non-UIA patients. DESIGN: Case-control study. SETTING: A tertiary university-affiliated hospital. PATIENTS: All postoperative children admitted to the PICU were monitored for UIA. About 28 cases and 88 controls were included. INTERVENTIONS: none. MEASUREMENTS AND MAIN RESULTS: The overall prevalence of UIA was 2.6%. About 28 patients (24.1%) of 116 had unplanned admission. Multiple logistic regression revealed that factors predicting UIA were airway abnormality (odds ratio 16.2, 95% confidence interval 2.65-99.6), anesthetic factors (odds ratio 5.8, 95% confidence interval 1.06-32.2), and hypoxia intraoperative (odds ratio 7.4, 95% confidence interval 1.21-46.24). Procedures on abdomen, emergency surgery, combined anesthesia, and occurrence of intraoperative adverse events were also risk factors for an UIA. Patients with UIA had longer duration of mechanical ventilation than non-UIA patients (4.5 vs. 2 days, p = 0.01), but there were no differences in length of PICU and hospital stays. Preventable adverse events were detected in 25% of UIA children. CONCLUSIONS: Airway abnormality, anesthetic factors, and hypoxia intraoperative were risk factors associated with UIA. Although preventable events contribute significantly to unplanned PICU admissions, they constitute a room of opportunity in quality improvement programs.

RESUMO

INTRODUCTION: Although lumbar puncture (LP) is a relatively straightforward procedure and is usually associated with low morbidity, rare and significant neurological complications can occur. Intramedullary spinal cord abscess (ISCA) after lumbar puncture is one of these serious complications; however, this complication has not yet been reported in children. CASE REPORT: After 27 days in another medical facility, a 1-year-old girl was admitted to our hospital with a diagnosis of fever of unknown origin. Prior to the second admission, she had undergone multiple traumatic LP attempts. The patient was referred to our institution with progressive and ascending weakness. Three days later, this weakness involved all of the patient's four limbs. A LP was performed and showed purulent cerebrospinal fluid (CSF). An emergent spinal magnetic resonance imaging was performed and revealed an intramedullary lesion extending from the T2 to L3 level. Broad-spectrum antibiotics and steroids were administered to the patient, and a T2-L3 laminectomy was performed. The postoperative course was uneventful, but a neurologic deficit, including lower limb paralysis, remained. CONCLUSION: The index of suspicion for a pyogenic infection of the intramedullary space should be higher if progressive flaccid paralysis develops within a few days after a lumbar procedure. Nevertheless, the diagnosis may be challenging due to the rarity of this condition. Any misdiagnosis or delay of adequate treatment may lead to unfavorable outcomes.

RESUMO

Elizabethkingia meningoseptica is an unusual, highly resistant, gram- negative bacillus. While E. meningoseptica-associated meningitis outbreaks have been well-documented in hospital neonatal wards and among immunocompromised adults, reports describing this microorganism in critically ill children are scarce. The purpose of this report was to describe a case of a 3 year-old girl who developed pneumonia caused by E. meningoseptica in the setting of previous use of broad-spectrum antibiotics and to review the pediatric literature regarding this pathogen.

RESUMO

BACKGROUND: In this study, we updated the state of knowledge on unplanned tracheal extubations in the intensive care unit. We focused on the following topics: incidence, risk factors, reintubation after unplanned extubation, outcomes, and prevention. Based on this review, recommendations were made for preventing unplanned extubations. METHODS: Electronic databases were searched for relevant publications from January 1, 1950 through June 30, 2011 on the MEDLINE, EMBASE, CINAHL, SciELO, LILACS, and Cochrane systems. Fifty articles were eligible for data abstraction. Study quality was assessed using the Newcastle-Ottawa Scale. Grades of recommendation were assessed according to the Oxford Centre for Evidence-Based Medicine. RESULTS: Unplanned extubations occur at a rate of 0.1 to 3.6 events per 100 intubation days. Risk factors associated with unplanned extubations included male gender (odds ratio [OR] 4.8), APACHE score ≥17 (OR 9.0), chronic obstructive pulmonary disease, restlessness/agitation (OR 3.3-30.6), lower sedation level (OR 2.0-5.4), higher consciousness level (OR 1.4-2.0), and use of physical restraints (OR 3.1). Reintubation rates ranged from 1.8% to 88% of unplanned extubations. Thirteen studies assessed preventive measures for avoiding unplanned extubations. These studies focused on data collection tools, standardization of procedures, staff education, staff surveillance, and identification and management of high-risk patients. These studies reported reductions in unplanned extubation rate from 22% to 53%. The best methods of securing the endotracheal tube and use of physical restraints remain controversial issues. CONCLUSIONS: Despite numerous publications on unplanned extubation, few studies assess preventive strategies for adverse events, and few clinical trials have assessed unplanned extubations. Recommendations are proposed based on the currently available literature.

RESUMO

OBJECTIVE: To evaluate the performance of the Transport Risk Index of Physiologic Stability (TRIPS) score at admission for early mortality prediction. METHODS: The study included all consecutive outborn infants admitted to a single neonatal intensive care unit (NICU) over a 3-year period. The data collected included demographic variables, 7-day NICU mortality, and severe (≥ grade 3) intraventricular hemorrhage (IVH), TRIPS score at admission, and Score for Neonatal Acute Physiology II (SNAP-II) and SNAP-Perinatal Extension-II (SNAPPE-II) scores. RESULTS: A total of 175 neonates were enrolled. TRIPS at admission discriminated 7-day mortality from survival with a receiver operating characteristic (ROC) area of 0.80, and predictive performance of TRIPS for severe IVH showed a ROC area of 0.67. The TRIPS had good calibration for all strata (p = 0.49). For gestational age (GA) >32 weeks, the area under the curve (AUC) for TRIPS was 0.71, whereas the AUC for GA ≤32 weeks was 0.99 for 7-day mortality. Predictive performance of TRIPS for 7-day mortality was similar to that of SNAP-II and SNAPPE-II. CONCLUSION: TRIPS score at admission had a good performance to discriminate high-risk patients for 7-day mortality, mainly infants with GA ≤32 weeks. TRIPS might be a useful triage tool if applied at the time of first contact with a transport service.

RESUMO

Aminophylline exerts a renovascular effect, acting by adenosine receptor blockade or type IV phosphodiesterase inhibition. Clinically, these drugs have been used with furosemide to induce diuresis in adults and neonates. However, reports on use of aminophylline in diuretic-dependent children are limited to a few studies. We report a case series of four critically ill children unresponsive to furosemide continuous infusion who were subsequently given aminophylline as an adjunct diuretic in the treatment of fluid overload. No side effects were evident. Administration of aminophylline at low doses (3 mg/kg) successfully promoted increased urine output over the 6-h study period in all four children.

RESUMO

OBJECTIVE: To assess the current evidence for the efficacy of care bundles in reducing unplanned extubations (UEs) in critically ill children. DESIGN: Systematic review according to the Cochrane guidelines and meta-analysis using random-effects modelling. METHODS: We searched MEDLINE, EMBASE, CINAHL, Web of Science, Scopus, Cochrane and SciELO databases from inception until April 2021. We conducted a quality appraisal for each study using the Newcastle-Ottawa Scale and Standards for Quality Improvement Reporting Excellence (SQUIRE) V.2.0 checklist. MAIN OUTCOME: The primary outcome measure was UE rates per 100 intubation days. RESULTS: We screened 10 091 records and finally included 11 studies. Six studies were pre/post-intervention studies, and five were interrupted time-series studies. The methodological quality was 'good' in 70%, and the remaining as 'fair' (30%). The most frequently used implementation strategies were staff education (100%), root cause analysis (100%), and audit and feedback (82%). Key bundle care components comprised identification of high-risk patients, endotracheal tube care and sedation protocol. Not all studies fully completed the SQUIRE V.2.0 checklist. Meta-analysis revealed a reduction in UE rate following the introduction of care bundles (rate ratio: 0.40 (95% CI: 0.19 to 0.84); p=0.02), which equates to a 60% reduction in UE rates. CONCLUSIONS: We found that identifying high-risk patients, endotracheal tube care and protocol-directed sedation are core elements in care bundles for preventing UEs. However, there are several methodological gaps in the literature, including poor evaluation of adherence to bundle components. Future studies should address these gaps to strengthen their validity.
