Abstract

Background: Airborne personal protective equipment is required for healthcare workers when performing aerosol-generating procedures on patients with infectious diseases. Chest compressions, one of the main components of cardiopulmonary resuscitation, require intense and dynamic movements of the upper body. We aimed to investigate the protective effect of tight-fitting powered air-purifying respirators (PAPRs) during chest compressions. Methods: This single-center simulation study was performed from February 2021 to March 2021. The simulated workplace protection factor (SWPF) is the concentration ratio of ambient particles and particles inside the PAPR mask; this value indicates the level of protection provided by a respirator when subjected to a simulated work environment. Participants performed continuous chest compressions three times for 2 min each time, with a 4-min break between each session. We measured the SWPF of the tight-fitting PAPR during chest compression in real-time mode. The primary outcome was the ratio of any failure of protection (SWPF <500) during the chest compression sessions. Results: Fifty-four participants completed the simulation. Overall, 78% (n = 42) of the participants failed (the measured SWPF value was less than 500) at least one of the three sessions of chest compressions. The median value and interquartile range of the SWPF was 4304 (685–16,191). There were no reports of slipping down of the respirator or mechanical failure during chest compressions. Conclusions: Although the median SWPF value was high during chest compressions, the tight-fitting PAPR did not provide adequate protection.

Abstract

Endo-tracheal tube obstruction due to an extensive blood clot is a recognized but very rare complication. A ball-valve obstruction in the airway could function as a check valve for the lung and thorax, resulting in tension pneumothorax-like abnormalities. A 47-year-old female patient had undergone implantation of a left ventricular assist device 3 weeks prior. On post-operative day 17, planned thoracentesis was performed for drainage of a pleural effusion. Despite the drainage, the patient’s oxygenation did not improve, and emergency tracheal intubation was conducted. Subsequent computed tomography revealed bilateral pneumothorax. Two days later, the patient’s trachea was extubated without complication, and a mini-tracheostomy tube was placed. Three hours later, reintubation was conducted due to progressive tachypnea. Although successful intubation was confirmed, ventilation became increasingly difficult and finally impossible. Marked increase in pulmonary artery and central venous pressures suggested progression of the previous tension pneumothorax. After emergency extracorporeal membrane oxygenation was initiated, fiberoptic bronchoscopy revealed the presence of a massive clot and ball-valve obstruction of the endotracheal tube. Two weeks later, the patient died due to severe hypoxic brain damage. Diagnosis of ball valve clot is not simple, but intensivists should consider this rare complication.

Abstract

High-flow nasal cannula (HFNC) oxygen is a therapy that has demonstrated survival benefits in acute respiratory failure (ARF). However, the role of HFNC in ARF due to interstitial pneumonia (IP) is unknown. The aim of this study was to compare the effects of HFNC therapy and non-invasive positive pressure ventilation (NPPV) in ARF due to IP. This retrospective observational study included 32 patients with ARF due to IP who were treated with HFNC (n = 13) or NPPV (n = 19). The clinical characteristics, intubation rate and 30-day mortality were analyzed and compared between the HFNC group and the NPPV group. Predictors of 30-day mortality were evaluated using a logistic regression model. HFNC group showed higher mean arterial blood pressure (median 92 mmHg; HFNC group vs 74 mmHg; NPPV group) and lower APACHEII score (median 22; HFNC group vs 27; NPPV group) than NPPV group. There was no significant difference in the intubation rate at day 30 between the HFNC group and the NPPV group (8% vs 37%: p = 0.069); the mortality rate at 30 days was 23% and 63%, respectively. HFNC therapy was a significant determinant of 30-day mortality in univariate analysis, and was confirmed to be an independent significant determinant of 30-day mortality in multivariate analysis (odds ratio, 0.148; 95% confidence interval, 0.025–0.880; p = 0.036). Our findings suggest that HFNC therapy can be a possible option for respiratory management in ARF due to IP. The results observed here warrant further investigation of HFNC therapy in randomized control trials.

Abstract

A 37-year-old man diagnosed with diffuse large B-cell lymphoma two weeks previously, visited our emergency department with sudden dyspnea. He had a severe respiratory failure with saturated percutaneous oxygen at 80% (room air). Chest radiography showed a large amount of left pleural effusion. After 1000 mL of the effusion was urgently drained, reexpansion pulmonary edema (RPE) occurred. Despite ventilator management, oxygenation did not improve and venovenous extracorporeal membrane oxygenation (VV-ECMO) was initiated in the intensive care unit. The next day, contrast-enhanced computed tomography showed a massive thrombus in the right pulmonary artery, at this point the presence of pulmonary thromboembolism (PTE) was revealed. Fortunately, the patient's condition gradually improved with anticoagulant therapy and VV-ECMO support. VV-ECMO was successfully discontinued on day 4, and chemotherapy was initiated on day 8. We speculated the following mechanism in this case: blood flow to the right lung significantly reduced due to acute massive PTE, and blood flow to the left lung correspondingly increased, which could have caused RPE in the left lung. Therefore, our observations suggest that drainage of pleural effusion when contralateral blood flow is impaired due to acute PTE may increase the risk of RPE. < Learning objective: This is a case of reexpansion pulmonary edema (RPE) in the left lung following acute pulmonary thromboembolism (PTE) in the right lung associated with malignant lymphoma, managed by venovenous extracorporeal membrane oxygenation. Contralateral pleural drainage could increase the risk of RPE because contralateral pulmonary blood flow is assumed to increase when PTE obstructs blood flow. Pleural drainage should be performed carefully in patients with malignant tumors because PTE may be hidden.>., (© 2020 Japanese College of Cardiology. Published by Elsevier Ltd.

Abstract

This is a 3-case report of successful descending thoracic and thoracoabdominal aortic surgery by preserving the spinal perfusion artery (SPA) identified preoperatively. In Case 1, an 85-year-old woman, computed tomography (CT) showed Crawford type Ⅴ thoracoabdominal aortic aneurysm (TAAA:60 mm) and a SPA originated from L2. In Case 2, a 76-year-old man, CT revealed type Ⅳ TAAA( 58 mm) and a SPA originated from Th11. In Case 3, a 74-year-old man, CT detected an infectious pseudoaneurysm(44 mm) in the descending thoracic aorta with 2 SPAs originating from Th10 and L2. The ranges of graft replacement were Th7-Th12, Th12-L4, and Th8-Th10, respectively, while preserving all SPAs. All patients recovered well without postoperative neurological deficits. Although the protective effect of the SPA preservation against the spinal cord ischemia is still controversial, preoperative identification of the SPA was useful for planning a surgical strategy for descending thoracic and thoracoabdominal aortic repair surgery.
