On January 2013, a disaster at Santa Maria (RS) due to a fire in a confined space caused 242 deaths, most of them by inhalation injury. On November 2013, four individuals required intensive care following smoke inhalation from a fire at the Memorial da América Latina in São Paulo (SP). The present article reports the clinical progression and management of disaster victims presenting with inhalation injury. Patients ERL and OC exhibited early respiratory failure, bronchial aspiration of carbonaceous material, and carbon monoxide poisoning. Ventilation support was performed with 100% oxygen, the aspirated material was removed by bronchoscopy, and cyanide poisoning was empirically treated with sodium nitrite and sodium thiosulfate. Patient RP initially exhibited cough and retrosternal burning and subsequently progressed to respiratory failure due to upper airway swelling and early-onset pulmonary infection, which were treated with protective ventilation and antimicrobial agents. This patient was extubated following improvement of edema on bronchoscopy. Patient MA, an asthmatic, exhibited carbon monoxide poisoning and bronchospasm and was treated with normobaric hyperoxia, bronchodilators, and corticosteroids. The length of stay in the intensive care unit varied from four to 10 days, and all four patients exhibited satisfactory functional recovery. To conclude, inhalation injury has a preponderant role in fires in confined spaces. Invasive ventilation should not be delayed in cases with significant airway swelling. Hyperoxia should be induced early as a therapeutic means against carbon monoxide poisoning, in addition to empiric pharmacological treatment in suspected cases of cyanide poisoning.
Objective To assess the impact of intracranial pressure monitoring on the short-term outcomes of traumatic brain injury patients.Methods Retrospective observational study including 299 consecutive patients admitted due to traumatic brain injury from January 2011 through July 2012 at a Level 1 trauma center in São Paulo, Brazil. Patients were categorized in two groups according to the measurement of intracranial pressure (measured intracranial pressure and non-measured intracranial pressure groups). We applied a propensity-matched analysis to adjust for possible confounders (variables contained in the Crash Score prognostic algorithm).Results Global mortality at 14 days (16%) was equal to that observed in high-income countries in the CRASH Study and was better than expected based on the CRASH calculator score (20.6%), with a standardized mortality ratio of 0.77. A total of 28 patients received intracranial pressure monitoring (measured intracranial pressure group), of whom 26 were paired in a 1:1 fashion with patients from the non-measured intracranial pressure group. There was no improvement in the measured intracranial pressure group compared to the non-measured intracranial pressure group regarding hospital mortality, 14-day mortality, or combined hospital and chronic care facility mortality. Survival up to 14 days was also similar between groups.Conclusion Patients receiving intracranial pressure monitoring tend to have more severe traumatic brain injuries. However, after adjusting for multiple confounders using propensity scoring, no benefits in terms of survival were observed among intracranial pressure-monitored patients and those managed with a systematic clinical protocol.
Objective Our aim was to assess the feasibility and preliminary results of implementing a telehealth system, Alice Agora, as a tool for optimizing health delivery in a new primary care-based health system. Results We had 4193 consultations over the last 6 months (February and August 2021). Preliminary results show patients high level of satisfaction (Consumer satisfaction score of 4.92). The chief complaints were related to upper respiratory tract (n = 1542; 28.5%), gastrointestinal (n = 781; 14.43%), musculoskeletal (n = 607; 11.22%), and other (n = 643; 11.88%). We found that 20.1% (842) of the cases were solved digitally, that is, by a chat only with a nurse, through the use of health protocols, and 43.9% were solved by nurses with medical assistance. Only 6.6% (277) of the cases had to be referred to the emergency room (ER). This means that 64% of the cases were completely resolved by our nurses-driven system. Forty-eight hours readmission rates were higher for the uncoordinated ER cases compared with the coordinated cases (14.81% vs. 5.87%; p = 0.016). The same pattern was observed for the 72-h readmission rates (16.67 vs. 7.26%; p = 0.02).
Uso de suporte hemodinâmico e respiratório por meio de oxigenação extracorpórea por membrana (ECMO) venoarterial em um paciente politraumatizado INTRODUCTIONThe use of extracorporeal membrane oxygenation (ECMO) as respiratory support has been widely acknowledged as a rescue technique for refractory hypoxemia in H1N1-infected patients.(1) Recently, our institution adopted the use of ECMO in the intensive care unit (ICU) for selected refractory cardiopulmonary dysfunction cases.In the venoarterial modality, venous blood is oxygenated and pumped back into the arterial system, providing total/nearly total cardiorespiratory support. This method is mostly used in patients who are difficult to wean from cardiopulmonary bypass following acute myocardial infarction or in cases of refractory cardiac arrest. (2) Few investigators have reported the use of ECMO for simultaneous posttraumatic cardiac and pulmonary dysfunctions. (3,4) In this article, we report the case of a 48-year-old male patient with cardiogenic shock and hypoxemia due to cardiac and pulmonary contusions, who was successfully supported by venoarterial ECMO until cardiorespiratory recovery. CASE REPORTA 48-year-old male patient, with no previous comorbidities, was brought to the emergency service of Hospital das Clínicas after a serious traffic accident (automobile versus motorcycle). The patient was a motorcycle rider who was not wearing a helmet. At the accident site, he had an oxygen saturation of ABSTRACTThere are few reports in the literature regarding the use of venoarterial extracorporeal membrane oxygenation (ECMO) for double-dysfunction from both heart and lung contusions in polytrauma patients. This article reports a 48-year-old patient admitted after a traffic accident. He rapidly progressed to shock with low cardiac output due to myocardial contusion and refractory hypoxemia due to pulmonary contusion, an unstable chest wall and bilateral pneumothorax. ECMO was an effective rescue procedure in this dramatic situation and was successfully discontinued on the fourth day after the trauma. The patient also developed an extensive brain infarction and eventually died on the seventh day after admission. Conflicts of interest:The ECMO membranes were donated by Maquet Cardiopulmonary.
