RESUMO

RESUMO Objetivo Avaliar modificações cardiorrespiratórias em decorrência de sessão única de oxigenoterapia hiperbárica. Método Estudo aleatorizado com pacientes: grupos-controle e oxigenoterapia hiperbárica. As avaliações ocorreram no início, durante e após a exposição ao oxigênio puro acima de uma atmosfera, durante 2 horas. A pressão arterial sistêmica, saturação periférica de oxigênio, frequência de pulso, volume e capacidade pulmonar, pressões inspiratória e expiratória máximas foram avaliadas. A saturação periférica de oxigênio, frequência de pulso e pressão arterial sistêmica foram avaliadas durante a pressurização na primeira hora. Os dados foram avaliados pelo teste de ANOVA, Mann-Whitney e teste t independente (p<0,05). Resultados Foram avaliados 14 pacientes adultos. No grupo sob terapia (sete sujeitos), idade: 49,57±14,59 anos houve redução da frequência de pulso de 16 batimentos por minuto após 35 minutos de terapia (análise intragrupo), e a saturação periférica de oxigênio foi maior neste mesmo período se comparado ao grupo-controle. Conclusão A oxigenoterapia hiperbárica promove alterações cardiorrespiratórias com o aumento da saturação periférica de oxigênio e redução da frequência de pulso, sem alterar os níveis pressóricos arteriais e a força, volumes e capacidades respiratórios.

ABSTRACT Objective To evaluate cardiorespiratory alterations due to a single session of hyperbaric oxygen therapy. Method Randomized study with patients: a control group and hyperbaric oxygen therapy. Evaluations occurred in the beginning, during, and after exposure to pure oxygen above atmosphere for 2 hours. Systemic blood pressure, peripheral oxygen saturation, pulse rate, lung volume and lung capacity, and maximal inspiratory and expiratory pressures were evaluated. Peripheral oxygen saturation, pulse rate, and systemic blood pressure were evaluated during the pressurizing in the first hour. Data were evaluated by means of ANOVA, Mann-Whitney, and independent t-test (p<0.05). Results A total of 14 adult patients were evaluated. In the group under therapy (seven subjects), aged: 49.57±14.59 years, there was a decrease in the pulse rate of 16 beats per minute after 35 minutes of therapy (intragroup analysis), and the peripheral oxygen saturation was higher within the same period compared to the control group. Conclusion The hyperbaric oxygen therapy promotes cardiorespiratory alterations with the increase of the peripheral oxygen saturation and decrease of the pulse rate, without altering blood pressure levels and the strength, volumes, and respiratory capacities.

RESUMO

INTRODUCTION: VACTERL association is an acronym that includes vertebral anomalies (V), anal atresia (A), cardiac defects (C), tracheoesophageal fistula (TEF) or esophageal atresia (EA), renal anomalies (R), and limb defects (L). Airway anomalies have rarely been reported with VACTERL association. PATIENT CONCERNS: A 10-month-old boy who had been diagnosed with anal atresia and received surgical corrections soon after birth consulted our institution by complaining repeated cough and fever. DIAGNOSIS: Diagnosis of VACTERL association was finally made. Bronchoscopy and chest CT with computed tomography angiography confirmed multiple airway abnormalities including bridging bronchus, airway malacia, and complete tracheal rings. INTERVENTIONS: Supplemental oxygen was provided and antibiotics was initiated. OUTCOMES: The patient resolved gradually and was discharged 10 days later. The follow-up showed the patient has remained well just with mild psychomotor retardation. CONCLUSION: Multiple airway anomalies may be seen in VACTERL association. It is worthwhile to make special note for evaluating the tracheobronchial pulmonary system by chest CT and bronchoscopy, especially patients presenting with breathing anomalies.

RESUMO

Current therapeutic methods for chronic thromboembolic pulmonary hypertension (CTEPH) can improve hemodynamic status and are expected to improve prognoses. However, some patients experience dyspnea during effort and continue supplemental oxygenation despite their hemodynamic status being fully improved. Considering the pathogenesis of CTEPH, the dead space and intrapulmonary shunt are assumed to be responsible for hypoxia in CTEPH, but their contributions are unclear. It is also unclear whether they are improved after treatment. The aim of this study was to investigate the implications of the dead space ratio (DSR) and the intrapulmonary shunt ratio (ISR) for hypoxia in CTEPH and treatment for CTEPH.We retrospectively measured the DSR and ISR of 23 consecutive patients with CTEPH. For 11 of these 23 (10 were treated by balloon pulmonary angioplasty, one with riociguat), we also measured these parameters before and after CTEPH treatments. Overall, the DSR and ISR were abnormally elevated (DSR: 0.63 ± 0.06; ISR: 0.20 ± 0.05). After treatment, mean pulmonary artery pressure was improved (from 40.3 ± 8.1 to 25.5 ± 2.7 mmHg). Although atrial oxygen saturation (SaO2), DSR and ISR were improved (SaO2: from 90.2 ± 3.2 to 93.7 ± 1.8%; DSR: from 0.64 ± 0.06 to 0.58 ± 0.05; ISR: from 0.20 ± 0.04 to 0.18 ± 0.02), these improvements were slight compared with that of mean pulmonary artery pressure.The DSR and ISR were abnormally elevated in patients with CTEPH and their improvement by treatment was limited. Only DSR can be a useful marker for normalization of hypoxia in CTEPH.

RESUMO

OBJECTIVE: High-flow nasal cannula oxygenation (HFNC) characterized as a new non-invasive respiratory support technology, has been widely used in recent years. Compared with conventional oxygen therapy (COT), non-invasive ventilation (NIV), HFNC can offset patient discomforts, and effectively arrest the deterioration of acute respiratory failure (ARF) in immunosuppressed patients. Although there is no benefit of HFNC over COT on reducing mortality in immunocompromised patients with ARF, HFNC is associated with a lower intubation rate and the improved prognosis of transplant recipients and solid cancer patients. Although the association between the prognosis of HFNC treatment and the pathogenic differences of ARF patients remains unknown, HFNC has, as one of the alternative methods for treating ARF in immunosuppressed patients, outstanding clinical significance. The treatment of HFNC in immunosuppressed patients with ARF, such as transplantation, malignancy, pneumocystis pneumonia, and interstitial pneumonia are reviewed in this article, in order to guide the clinical application of HFNC in such patients.

RESUMO

BACKGROUND: Oxygen is like any other medication that can cause severe consequences if administered inappropriately. OBJECTIVE: To audit the pattern of acute oxygen therapy on regular hospital wards of a referral centre in Ilorin, Nigeria. METHODS: We reviewed 150 patients that received or had a prescription for acute oxygen therapy in three months and extracted relevant information using a proforma. RESULTS: About one-third of the patients (30%) were >65 years of age and the male to female ratio was 1:1. The commonest indication and medical condition for acute oxygen administration were hypoxemia (70.7%) and pneumonia (26.0%), respectively. Pneumonia accounted for most (41.2 %) of the oxygen therapy in childhood. The majority of patients (88.0%) had written order for oxygen prescription, 40.7% had a prescription to target oxygen saturation and only 31.3% achieved their target saturation. Oxygen prescription was adequate (documentation of delivery device, flow rate of oxygen, and target oxygen saturations) in 40.7% of patients. The assessment, monitoring and titration of oxygen therapy were adequate in 92.7%, 65.3% and 28 % of patients respectively. Overall mortality was 27.3% in patients receiving acute oxygen supplementation. Eleven patients had unstable COPD, and 63.6 %, 54.5 % and 45.6 % of them had adequate oxygen prescription, monitoring and titration respectively. The challenges to oxygen use were faulty delivery devices, emptied oxygen cylinders, inability to routinely do arterial blood gas analysis and lack of hospital oxygen protocol. CONCLUSION: The current practice of acute oxygen therapy is not satisfactory and interventions are advocated to improve the healthcare providers' administration of oxygen.

RESUMO

BACKGROUND: In some low-resource settings bubble continuous positive airway pressure (bCPAP) is increasingly used to treat children with pneumonia. However, the time required for healthcare workers (HCWs) to administer bCPAP is unknown and may have implementation implications. This study aims to compare HCW time spent administering bCPAP and low-flow nasal oxygen care at a district hospital in Malawi during CPAP IMPACT (Improving Mortality for Pneumonia in African Children Trial). METHODS: Eligible participants were 1-59 months old with WHO-defined severe pneumonia and HIV-infection, HIV-exposure, severe malnutrition, or hypoxemia and were randomized to either bCPAP or oxygen. We used time motion techniques to observe hospital care in four hour blocks during treatment initiation or follow up (maintenance). HCW mean time per patient at the bedside over the observation period was calculated by study arm. RESULTS: Overall, bCPAP required an average of 34.71 min per patient more than low-flow nasal oxygen to initiate (bCPAP, 118.18 min (standard deviation (SD) 42.73 min); oxygen, 83.47 min (SD, 20.18 min), p < 0.01). During initiation, HCWs spent, on average, 12.45 min longer per patient setting up bCPAP equipment (p < 0.01) and 11.13 min longer per patient setting up the bCPAP nasal interface (p < 0.01), compared to oxygen equipment and nasal cannula set-up. During maintenance care, HCWs spent longer on average per patient adjusting bCPAP, compared to oxygen equipment (bCPAP 4.57 min (SD, 4.78 min); oxygen, 1.52 min (SD, 2.50 min), p = 0.03). CONCLUSION: Effective bCPAP implementation in low-resource settings will likely create additional HCW burden relative to usual pneumonia care with oxygen.

RESUMO

La neumonía adquirida en la comunidad (NAC) constituye una causa frecuente de hospitalización y mortalidad en pacientes internados. Distintas escalas pronósticas como el CURB-65 o el Indice de Severidad de la Neumonía (PSI) son utilizados al valorar la admiisión hospitalaria de un paciente con NAC. La hipoxemia es una complicación frecuente de la neumonía. A pesar de esto, hasta nuestro conocimiento, el tiempo requerido de oxigenoterapia en pacientes con NAC hospitalizados en una sala general no ha sido evaluada. Los objetivos del presente estudioi fueron: evaluar los días de oxigenoterapia en pacientes con NAC y su correlación con el puntaje de PSI obtenido en la admisión. Cuarenta y seis pacientes fueron evaluados en forma prospectiva. El promedio general de días de utilización de oxigenoterapia fue de 6,25±5.93 días. Los mayores de 60 años requirieron 2 días más de oxigenoterapia que los más jóvenes (6.7±3.57 vs 4.3±2.70 días, p: 0,07). La media del PSI fue de 135,76±29,94 puntos para mayores de 60 años y 63±30 puntos para los más jóvenes equivalente a las clases de riesgo V y II respectivamente. Los días de oxigenoterapia fueron 7,38±4,09 días para los pacientes de clase V y 3.5±3,53 días para los pacientes de clase I. El coeficiente de correlación lineal entre puntaje PSI y días de oxigenoterapia fue de 0,34 equivalente a una correlación positiva baja. Futuras investigaciones, que incluyan un mayor número de pacientes, serán necesarias en pos de encontrar herramientas pronósticas sobre oxigenoterapia en NAC (AU)


Duration of oxygen therapy in patients with community-acquired pneumonia and its relationship with the Pneumonia Severity Index (PSI). Community-acquired pneumonia (CAP) is one of the most common cause of morbidity and mortality in hospitalized patients. Mayor decision of admission to the hospital, included severity of illness score (CURB-65) or prognostics models such as the Pneumonia Severity Index (PSI). Decreased of arterial PO2 un blood gas analysis, occurred in many patients with pneumonia. However, the mean duration of oxygen utilization in patients with CAP has not been evaluated. The goals of the present study were to evaluate the duration in days of oxygen therapy in patients with CAP and correlate the duration of this therapy with the PSI score obtained on admission of the patients. Forty-six patients were prospectively studied. Mean duration of oxygen therapy was 6.25±5,93 days. Patients older than 60 years required 2 days more of oxygen therapy compared with younger population (6,7±3,57 vs 4,3±2,70 days, p: 0,07), Mean PSI was 135,76±29,94 points for patients older than 60 years (class V) and 64±30 points for patients younger than 60 years (class II). Duration of oxygen therapy was 7,38±4,09 days for patients in Class V and 3,50±3,53 days for patients in Class I. Pearson correlation coefficient between PSI and days of oxygen therapy was 0,34, equivalent to a low positive linear correlation. Future studies of larger populations in the duration and utilization of oxygen treatment in hospitalized patients with CAP (AU)

RESUMO

Two landmark studies demonstrated survival benefit in chronic obstructive pulmonary disease (COPD) complicated by chronic hypoxaemia with the prescription of long-term oxygen therapy (LTOT). Best practice evidence therefore recommends that individuals with stable COPD and resting hypoxaemia (PaO2≤7.3 kPa) should be assessed for long-term oxygen therapy. However, it is estimated that up to one-quarter of COPD patients prescribed LTOT continue to smoke. Oxygen therapy consequently presents an obvious fire hazard in the case of such patients, who are therefore at greater risk of death or sustaining devastating head and neck burns. This article critically analyses, through the context of a care study, the professional, ethical and legal issues involved in making a safe prescribing decision for LTOT in an individual with COPD who is a current smoker. Home oxygen prescription is a growing trend in the COPD population, and it is important for nurse prescribers to be aware of the issues highlighted in the article to ensure safe prescribing practices.

RESUMO

Until now, we routinely administered oxygen to trauma patients in prehospital settings irrespective of whether oxygen delivery affected the prognosis. To determine the necessity of prehospital oxygen administration (POA) to trauma patients, we aimed to assess whether POA contributed to in-hospital mortality.This was a multicenter propensity-matched cohort study involving 172 major emergency hospitals in Japan. During 2004 to 2010, 70,683 patients with trauma aged ≥15 years were eligible for enrolment. The main outcome measures were survival until hospital discharge after POA, and propensity score analyses were used to adjust for patient factors and hospital site.Of 32,225 trauma patients, 19,985 (62.0%) were administered oxygen by the emergency medical services in prehospital settings and 12,240 (38.0%) did not receive oxygen. Overall, 29,555 patients (90.7%) survived till hospital discharge. In the multivariable unconditional logistic regression, POA had an odds ratio (OR) of 0.33 (95% confidence interval [CI], 0.30-0.37; P <.001) for favorable in-hospital mortality. Furthermore, there were significant differences in all the important variables between the POA and no POA groups (P <.001); therefore, we used propensity score matching analysis. After adjustment for the covariates of selected variables, we found that POA was not associated with a higher rate of survival after hospitalization (adjusted OR, 1.02; 95% CI, 0.99-1.04; P = .27). Even after adjustment for all covariates, POA did not improve in-hospital mortality (adjusted OR, 1.01; 95% CI, 0.99-1.03; P = .08).In this study, POA did not improve in-hospital mortality in trauma patients. However, further studies are needed to validate our results.

RESUMO

OBJECTIVE: To investigate the characteristics and failure risk factors of sequential high-flow nasal cannula oxygen therapy (HFNC) after weaning from invasive ventilation. METHODS: The patients who received sequential HFNC after weaning from invasive ventilation admitted to surgical intensive care unit (ICU) of Peking University People's Hospital from June 1st 2016 to May 31st 2018 were retrospectively analyzed. Clinical variables, respiratory therapy parameters, respiratory variables, cardiac variables and outcomes were reviewed and analyzed. Treatment characteristics of HFNC after weaning was analyzed. Patients were divided into HFNC success group and HFNC failure group according to the failure of HFNC, and the differences between the two groups were compared. The independent risk factors of HFNC treatment failure were analyzed by Logistic regression analysis. The value of predictive treatment failure of risk factors and regression models were analyzed by receiver operating characteristic (ROC) curve. RESULTS: A total of 99 patients were included, 61 men, and the median age was 67.0 (57.0, 76.0) years old. The medianinitial HFNC flow was 50 (50, 60) L/min, and inspired oxygen concentration (FiO2) was 0.50 (0.40, 0.60). Eighteen patients experienced HFNC failure (18.2%). Compared with the HFNC success group, the sequential organ failure assessment (SOFA) score in the HFNC failure group was higher [4 (3, 5) vs. 2 (1, 3), P < 0.01], B type natriuretic peptide (BNP) before HFNC therapy were significant higher [ng/L: 647.2 (399.2, 1 331.3) vs. 127.2 (55.2, 369.5), P < 0.01], and respiratory frequency (RR) and heart rate (HR) were significant faster, mean arterial pressure (MAP) was significant higher, oxygen index (PaO2/FiO2) was significant lower after 30 minutes HFNC treatment [RR (times/min): 26 (22, 28) vs. 19 (17, 21), HR (bpm): 105 (97, 107) vs. 85 (77, 90), MAP (mmHg, 1 mmHg = 0.133 kPa): 104.3 (101.7, 110.7) vs. 92.3 (88.3, 97.7), PaO2/FiO2 (mmHg): 207.3 (185.8, 402.8) vs. 320.2 (226.2, 361.5), all P < 0.05]. It was shown by multiple Logistic regression analysis that the SOFA score [odds ratio (OR) = 2.818, P = 0.022, ß = 1.036], BNP before HFNC treatment (OR = 1.002, P = 0.033, ß = 0.002) and HR after HFNC treatment 30 minutes (OR = 1.140, P = 0.032, ß = 0.131) were independent risk factors for HFNC treatment failure. It was shown by ROC curve that the area under the ROC curve (AUC) for the prediction of HFNC failure was 0.840, 0.859, 0.860 and 0.962 for SOFA, BNP before HFNC treatment, HR after HFNC treatment 30 minutes, and regression model, all had good forecast values (all P < 0.01). CONCLUSIONS: HFNC is one of the commonly used oxygen therapy methods in the ICU, but not all patients who are treated as a sequential therapy after invasive mechanical ventilation weaning can benefit from it. SOFA score, BNP before HFNC treatment and HR after 30 minutes HFNC treatment were independent risk factors of HFNC failure. Each independent risk factor and regression model can predict the success of HFNC treatment.

RESUMO

OBJECTIVE: To determine the high-risk factors for early failure of high-flow nasal cannula (HFNC) oxygen therapy in children with acute respiratory insufficiency (ARI). METHODS: The clinical data of 123 children with ARI were reviewed who received HFNC oxygen therapy in the pediatric intensive care unit from January to June, 2018. The children who did not require an upgrade of respiratory support during hospitalization and were successfully weaned from HFNC were classified as HFNC success group (69 cases). Of the remaining children (54 cases) who required an upgrade of their respiratory support during hospitalization, those that needed to upgrade their respiratory support within 48 hours of receiving HFNC were classified as early HFNC failure group (46 cases). Risk factors for early failure of HFNC were determined using multivariate logistic regression analysis. RESULTS: The incidence rates of shock, sepsis, intracranial hypertension syndrome, and multiple organ dysfunction syndrome were significantly higher in the early HFNC failure group than in the HFNC success group (P<0.05). Before implementation of respiratory support, the early HFNC failure group had significantly lower Glasgow coma score, pH value, and oxygenation index and significantly higher Pediatric Risk of Mortality (PRISM) score and PaCO2/PaO2 ratio than the HFNC success group (P<0.05). Multivariate logistic regression analysis showed that PRISM score >4.5 and PaCO2/PaO2 ratio >0.64 were independent risk factors for early HFNC failure (OR=5.535 and 9.089 respectively; P<0.05). CONCLUSIONS: Pediatric ARI patients with PRISM score >4.5 or PaCO2/PaO2 ratio >0.64 have relatively high risk of early HFNC failure.

RESUMO

RATIONALE: Rigid bronchoscopy under general anesthesia enables performing diagnostic and/or therapeutic procedures in the tracheobronchial tree. As most patients undergoing rigid bronchoscopy have moderate to severe respiratory disease or central airway obstruction, the operators often face the risk of hypoxemia when inserting the rigid bronchoscope into the patients' airway. Applying high flow nasal cannula (HFNC) oxygen therapy before the insertion of the bronchoscope allows to maintain high fractional inspired oxygen (FiO2) and thus leading to maximizing apnea time before desaturation. PATIENT CONCERNS AND DIAGNOSIS: Case 1: A 70-year-old female patient was diagnosed with lung cancer in the left lower lobe and a tracheal mass of about 2.6 cm * 0.8 cm in size.Case 2: A male patient, 77 years old, 55.7 kg and 157.3 cm in height, had been diagnosed with chronic obstructive pulmonary disease, and was scheduled for the bronchoscopic volume reduction surgery upon exacerbation of his symptoms of dyspnea and cough with sputum. INTERVENTIONS: Preoxygenation was performed with HFNC (Fisher&Paykel Optiflow Thrive, New Zealand) for 3 minutes before the administration of anesthetic medications. The oxygen flow was set at 50 L/min and the FiO2 at 1.0. SpO2 increased to 100%. OUTCOMES: The HFNC oxygen has shown its effectiveness in safely maintaining the patients' SpO2 during the prolonged apneic period of inserting bronchoscope. LESSONS: HFNC oxygen is an effective tool in oxygenating the patients during the induction of rigid bronchoscopy, and that it may be a superior alternative to the conventional method of preoxygenation.
