Nevertheless, providing home non-invasive positive pressure ventilation encounters several challenges, including compliance, training inadequacies, and limited resources. Therefore, the objective of this study was to observe the impact of home non-invasive positive pressure ventilation on patients with chronic respiratory failure, specifically focusing on its effects on the mean pulmonary artery pressure, diaphragmatic excursion, and associated complications. Results The study included a total of 48 patients, consisting of 26 males (54.1%) and 22 females (45.9%). The baseline mean pulmonary artery pressure (PAP) was found to be 39.79 ± 7.51. Additionally, the baseline diaphragmatic excursion in quiet breathing was measured to be 1.80 ± 0.38 cm, while the baseline diaphragmatic excursion in deep breathing was recorded as 4.35 ± 0.99 cm. Following the implementation of home non-invasive ventilation, specifically bilevel-positive airway pressure or continuous positive airway pressure, significant improvements were observed in the aforementioned parameters. The most commonly reported complications among the patients included skin ulcers and aerophagia. Furthermore, mortality rate of 6.3% was observed. Conclusions The use of home non-invasive positive pressure ventilation has been shown to be a successful and sustainable therapeutic approach for persons suffering from chronic respiratory failure. This therapy method has significantly improved PAP, diaphragm force, and overall mortality rates. The use of ultrasonography to evaluate pulmonary pressure or diaphragmatic excursion is considered a beneficial and straightforward approach for the follow-up of subjects with chronic respiratory failure.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135591935","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim To evaluate the role of early use of continuous positive airway pressure (CPAP) in management of moderate to severe COVID-19 patients at risk of OSA. Settings and design This was experimental clinical trial. Patients and methods Eighty (80) patients with moderate to severe COVID-19 at risk of OSA were enrolled. They were simply randomized into two equal groups: non-CPAP group and CPAP group. Non-CPAP group will receive medical treatment plus oxygen therapy according to recommendation of protocol of the Egyptian Ministry of Health 2020 and CPAP group as in non-CPAP group plus using CPAP. Results Our findings showed that there were higher percentages in hospital deaths and longer duration of hospital stay as well as increased need for invasive mechanical ventilation in non-CPAP group compared to CPAP group patients: ( P -value = 0.03), ( P -value = 0.04), and ( P -value = 0.01), respectively.

Failure to decannulate may result from several reasons, such as severe dysphagia, retention of copious secretions requiring invasive airway clearing techniques, or tracheal stenosis. Meanwhile, the combined use of either non-invasive ventilation during bronchoscopy has been reported as a successful strategy in different diagnostic and therapeutic clinical conditions. Case presentation We describe a patient admitted to the intensive care unit due to respiratory failure after a decannulation process and the use of non-invasive ventilation as rescue therapy during urgent flexible bronchoscopy to support this procedure and control acute hypercapnic respiratory failure and avoid recannulation process.

Although ECMO therapy has advanced significantly, complications like thrombosis and bleeding continue to be substantial, necessitating rapid transport of patients to the radiology suite to reveal crucial findings for further treatment plans or care. Even though the low flow rate for veno-arterial ECMO (VA-ECMO) support during contrast-enhanced CT is well known, the flow rate for veno-venous ECMO support during CT, especially computed tomography pulmonary angiography, is not well understood. Our case emphasizes that CTPA can be performed safely in trauma patients with ECMO runs and any suspected complications during ECMO runs may delay or worsen the clinical prognosis therefore immediate radiological verdicts may reveal significant findings to plan the treatment accordingly. Also, there were no complications associated with our examinations or transport. Our case highlights that VV-ECMO like VA-ECMO induces flow-dependent alterations in the patient’s circulation due to contrast injections, which might lead to an incorrect interpretation of CTPA. However, CTPA is safe, and bringing down the VV-ECMO flow rate of zero with vigilant monitoring of vitals and ventilation support helps radiologists to predict and interpret the contrast flow based on injection and cannula sites in the diagnosing and evaluation of pulmonary embolism patients with acute respiratory failure during ECMO.","PeriodicalId":34128,"journal":{"name":"Egyptian Journal of Bronchology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2023-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135395674","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recurrent hypoxia, which accompanies OSAHS, increases the degradation of ATP, which in turn increase uric acid concentration that can be used as a biomarker of tissue hypoxia in OSAHS. There is still debate about whether OSAHS is an independent contributor to pulmonary arterial hypertension. Aim of the work This study aimed to correlate serum uric acid levels and PAH in OSAHS patients. Methods We enrolled 100 patients diagnosed with OSAHS using polysomnography. Patients were divided into three severity groups: mild OSA (5 ≤ AHI < 15), moderate OSA (15 ≤ AHI < 30), and severe (30 ≤ AHI < 60). Serum uric acid was measured the morning after polysomnography. All patients underwent standard echocardiograms, and pulmonary artery systolic pressure calculation was done. Results Among our studied patients (66% males, 34% females), the mean age was 53.04 ± 8.45 years. Six percent, 38%, and 56% were diagnosed as mild, moderate, and severe OSAHS, respectively. The mean AHI was 31.93 ± 11.78 event. Pulmonary HTN was detected in 78% of patients. Those with elevated uric acid levels represented 92.3% of patients versus 9.1% of patients without pulmonary HTN, p < 0.001.

Medical history, anthropometric measures, and full night-attended polysomnography were done. Results Regarding STOP-Bang questionnaire, there was a statistically significantly higher proportion of women with hypertension, BMI more than 35 kg/m2, and neck size more than 17.5 cm in the postmenopausal group compared with the premenopausal group (P<0.05). The presence of restless leg syndrome was reported in 87.9% of the postmenopausal compared with 81% in the premenopausal group.
