Cánula nasal de alto flujo en pacientes críticos: una revisión narrativa / High Flow Nasal Cannula in Critically Ill Patients: a Narrative Review

La cánula nasal de alto flujo se ha convertido en una de las principales estrategias de soporte ventilatorio no invasivo en la insuficiencia respiratoria aguda hipoxémica, principalmente después de la pandemia de COVID-19. Sin embargo, su uso se extiende más allá de este escenario y abarca diferentes condiciones clínicas como el período postextubación, período postquirúrgico, insuficiencia respiratoria hipercápnica y soporte vital en pacientes inmunodeprimidos, trasplantados u oncológicos. Los manuscritos que avalan su aplicación han sido ampliamente difundidos y el grado de evidencia es lo suficientemente alto como para recomendar su uso. Por tanto, es necesario destacar sus efectos fisiológicos como el confort, una fracción inspirada de oxígeno precisa, el lavado de CO2 o la optimización del volumen pulmonar de fin de espiración para comprender su mecanismo de acción y mejorar los resultados de los pacientes. El objetivo de esta revisión narrativa es ofrecer un resumen breve y conciso de los efectos y beneficios de aplicar esta terapia en diferentes escenarios clínicos sin la estructura rígida de una revisión sistemática. Con base en estas líneas, el lector curioso puede ampliar la evidencia científica que avala el empleo de la cánula nasal de alto flujo en cada escenario particular. (AU);

High-flow nasal cannula has become one of the main strategies for non-invasive ventilatory support in hypoxemic acute respiratory failure, mainly after the COVID-19 pandemic. However, its use extends beyond this scenario and covers different clinical conditions such as the post-extubation period, post-surgical period, hypercapnic respiratory failure and life support in immunosuppressed, trasplant or cancer patients. Manuscripts that support its application have been widely disseminated and the degree of evidence is high enough to recommend its use. Therefore, it is necessary to highlight its physiological effects such as comfort, precise fraction of inspiratory oxygen, CO2 lavage or optimize end-expiratory lung volume to understand its mechanism of action and improve patients' outcomes. The objective of this narrative review is to offer a brief and concise summary of the benefits of applying this therapy in different clinical scenarios without the rigid structure of a systematic review. Based on these lines, the curious reader can expand the scientific evidence that supports the use of the high-flow nasal cannula in each particular scenario. (AU);

Perioperative mortality and morbidity of hip fractures among COVID-19 infected and non-infected patients: A systematic review and meta-analysis / 中华创伤杂志(英文版)

PURPOSE@#Hip fractures among elderly patients are surgical emergencies. During COVID-19 pandemic time, many such patients could not be operated at early time because of the limitation of the medical resources, the risk of infection and redirection of medical attention to a severe infective health problem.@*METHODS@#A search of electronic databases (PubMed, Medline, CINAHL, EMBASE and the Cochrane Central Register of Controlled Trials) with the keywords "COVID", "COVID-19″, "SARS-COV-2", "Corona", "pandemic", "hip fracture", "trochanteric fracture" and "neck femur fracture" revealed 64 studies evaluating treatment of hip fracture in elderly patients during COVID-19 pandemic time. The 30-day mortality rate, inpatient mortality rate, critical care/special care need, readmission rate and complications rate in both groups were evaluated. Data were analyzed using Review Manager (RevMan) V.5.3.@*RESULTS@#After screening, 7 studies were identified that described the mortality and morbidity in hip fractures in both COVID-19 infected (COVID-19 +) and non-infected (COVID-19 -) patients. There were significantly increased risks of 30-day mortality (32.23% COVID-19 + death vs. 8.85% COVID-19 - death) and inpatient mortality (29.33% vs. 2.62%) among COVID-19 + patients with odds ratio (OR) of 4.84 (95% CI: 3.13 - 7.47, p < 0.001) and 15.12 (95% CI: 6.12 - 37.37, p < 0.001), respectively. The COVID-19 + patients needed more critical care admission (OR = 5.08, 95% CI: 1.49 - 17.30, p < 0.009) and they remain admitted for a longer time in hospital (mean difference = 3.6, 95% CI: 1.74 - 5.45, p < 0.001); but there was no difference in readmission rate between these 2 groups. The risks of overall complications (OR = 17.22), development of pneumonia (OR = 22.25), and acute respiratory distress syndrome/acute respiratory failure (OR = 32.96) were significantly high among COVID-19 + patients compared to COVID-19 - patients.@*CONCLUSIONS@#There are increased risks of the 30-day mortality, inpatient mortality and critical care admission among hip fracture patients who are COVID-19 +. The chances of developing pneumonia and acute respiratory failure are more in COVID-19 + patients than in COVID-19 ‒ patients.

Superiority of sugammadex in preventing postoperative pulmonary complications / 中华医学杂志(英文版)

BACKGROUND@#Postoperative pulmonary complications often lead to increased mortality and financial burden. Residual paralysis plays a critical role in postoperative pulmonary complications. This meta-analysis was performed to determine whether sugammadex overmatches neostigmine in reducing postoperative pulmonary complications.@*METHODS@#PubMed, Embase, Web of Science, Medline through Ovid, Cochrane Library, Wanfang, China National Knowledge Infrastructure, and Chinese BioMedical Literature Databases were searched from their inception to 24 June, 2021. Random effects models were used for all analyses. Cochrane risk of bias tool was used to assess the quality of RCTs, while Newcastle Ottawa Quality Assessment Scale was used to assess for the quality of cohort studies.@*RESULTS@#Seventeen studies were included in the meta-analysis. Pooled data from cohort studies showed reversing neuromuscular blocking with sugammadex had less risk of compound postoperative pulmonary complications (relative risk [RR]: 0.73; 95% confidence interval [CI]: 0.60-0.89; P  = 0.002; I2  = 81%), pneumonia (RR: 0.64; 95% CI: 0.48-0.86; I2  = 42%) and respiratory failure (RR: 0.48; 95% CI: 0.41-0.56; I2  = 0%). However, pooled data from RCTs did not show any difference between the two groups in pneumonia (RR: 0.58; 95% CI: 0.24-1.40; I2  = 0%) and no respiratory failure was reported in the included RCTs. The difference was not found between sugammadex and neostigmine about atelectasis in pooled data from either RCTs (RR: 0.85; 95% CI: 0.69-1.05; I2  = 0%) or cohort studies (RR: 1.01; 95% CI: 0.87-1.18; I2  = 0%).@*CONCLUSION@#The evidence of superiority of sugammadex was limited by the confounding factors in cohort studies and small scale of RCTs. Whether sugammadex precedes neostigmine in preventing pulmonary complications after surgery is still unknown. Well-designed RCTs with large scale are needed.@*REGISTRATION@#PROSPERO ( https://www.crd.york.ac.uk/PROSPERO/ ); CRD 42020191575.

Design and application of decompression fixator to prevent HFNC facial pressure injury / 中华危重病急救医学

As a new respiratory support technique, high-flow nasal cannula oxygen therapy (HFNC) has been widely used in clinical practice in recent years. During HFNC treatment, due to the long time and continuous wearing of nasal stopper and fasteners on the patient face, it is easy to cause medical device-related pressure injury on multiple facial skin. Moreover, when the patient's position changes greatly, because there is no good fixed design at the HFNC nasal stopper, it is easy to shift or turn the nasal stopper outward, causing abnormal ventilation and failure to achieve the purpose of clinical oxygen therapy. To overcome above problems, medical staff in the intensive care unit of department of infectious diseases, Tongji Hospital Tongji Medical College of HUST designed a new type of decompression fixator to prevent HFNC face pressure injury, and obtained national utility model patent (ZL 2022 2 0754626.1). The integrated design structure of the device has the functions of decompression of facial skin and fixation of nasal stopper, which can ensure the effect of oxygen therapy and improve the oxygen therapy experience and patient comfort, which is suitable for clinical promotion.

Clinical characteristics of plastic bronchitis and risk factors for recurrence in children / 中国当代儿科杂志

OBJECTIVES@#To study the clinical characteristics of plastic bronchitis (PB) in children and investigate the the risk factors for recurrence of PB.@*METHODS@#This was a retrospective analysis of medical data of children with PB who were hospitalized in Children's Hospital of Chongqing Medical University from January 2012 to July 2022. The children were divided into a single occurrence of PB group and a recurrent PB group and the risk factors for recurrence of PB were analyzed.@*RESULTS@#A total of 107 children with PB were included, including 61 males (57.0%) and 46 females (43.0%), with a median age of 5.0 years, and 78 cases (72.9%) were over 3 years old. All the children had cough, 96 children (89.7%) had fever, with high fever in 90 children. Seventy-three children (68.2%) had shortness of breath, and 64 children (59.8%) had respiratory failure. Sixty-six children (61.7%) had atelectasis and 52 children (48.6%) had pleural effusion. Forty-seven children (43.9%) had Mycoplasma pneumoniae infection, 28 children (26.2%) had adenovirus infection, and 17 children (15.9%) had influenza virus infection. Seventy-one children (66.4%) had a single occurrence of PB, and 36 cases (33.6%) had recurrent occurrence of PB (≥2 times). Multivariate logistic regression analysis showed that involvement of ≥2 lung lobes (OR=3.376) under bronchoscopy, continued need for invasive ventilation after initial removal of plastic casts (OR=3.275), and concomitant multi-organ dysfunction outside the lungs (OR=2.906) were independent risk factors for recurrent occurrence of PB (P<0.05).@*CONCLUSIONS@#Children with pneumonia accompanied by persistent high fever, shortness of breath, respiratory failure, atelectasis or pleural effusion should be highly suspected with PB. Involvement of ≥2 lung lobes under bronchoscopy, continued need for invasive ventilation after initial removal of plastic casts, and concomitant multi-organ dysfunction outside the lungs may be risk factors for recurrent occurrence of PB.

Therapeutic efficacy of volume-guaranteed high frequency oscillation ventilation on respiratory failure in preterm infants with a gestational age of 28-34 weeks: a prospective randomized controlled study / 中国当代儿科杂志

OBJECTIVES@#To investigate the therapeutic efficacy of volume-guaranteed high frequency oscillation ventilation (HFOV-VG) versus conventional mechanical ventilation (CMV) in the treatment of preterm infants with respiratory failure.@*METHODS@#A prospective study was conducted on 112 preterm infants with respiratory failure (a gestational age of 28-34 weeks) who were admitted to the Department of Neonatology, Jiangyin Hospital Affiliated to Medical School of Southeast University, from October 2018 to December 2022. The infants were randomly divided into an HFOV-VG group (44 infants) and a CMV group (68 infants) using the coin tossing method based on the mode of mechanical ventilation. The therapeutic efficacy was compared between the two groups.@*RESULTS@#After 24 hours of treatment, both the HFOV-VG and CMV groups showed significant improvements in arterial blood pH, partial pressure of oxygen, partial pressure of carbon dioxide, and partial pressure of oxygen/fractional concentration of inspired oxygen ratio (P<0.05), and the HFOV-VG group had better improvements than the CMV group (P<0.05). There were no significant differences between the two groups in the incidence rate of complications, 28-day mortality rate, and length of hospital stay (P>0.05), but the HFOV-VG group had a significantly shorter duration of invasive mechanical ventilation than the CMV group (P<0.05). The follow-up at the corrected age of 6 months showed that there were no significant differences between the two groups in the scores of developmental quotient, gross motor function, fine motor function, adaptive ability, language, and social behavior in the Pediatric Neuropsychological Development Scale (P>0.05).@*CONCLUSIONS@#Compared with CMV mode, HFOV-VG mode improves partial pressure of oxygen and promotes carbon dioxide elimination, thereby enhancing oxygenation and shortening the duration of mechanical ventilation in preterm infants with respiratory failure, while it has no significant impact on short-term neurobehavioral development in these infants.

Congenital pulmonary alveolar proteinosis in a neonate / 中国当代儿科杂志

The male patient was referred to the hospital at 44 days old due to dyspnea after birth and inability to wean off oxygen. His brother died three days after birth due to respiratory failure. The main symptoms observed were respiratory failure, dyspnea, and hypoxemia. A chest CT scan revealed characteristic reduced opacity in both lungs with a "crazy-paving" appearance. The bronchoalveolar lavage fluid (BALF) showed periodic acid-Schiff positive proteinaceous deposits. Genetic testing indicated a compound heterozygous mutation in the ABCA3 gene. The diagnosis for the infant was congenital pulmonary alveolar proteinosis (PAP). Congenital PAP is a significant cause of challenging-to-treat respiratory failure in full-term infants. Therefore, congenital PAP should be considered in infants experiencing persistently difficult-to-treat dyspnea shortly after birth. Early utilization of chest CT scans, BALF pathological examination, and genetic testing may aid in early diagnosis.

Expert Consensus on Acute Respiratory Failure in Critically Ill Cancer Patients (2023) / 中国医学科学杂志(英文版)

Objective This consensus aims to provide evidence-based recommendations on common questions in the diagnosis and treatment of acute respiratory failure (ARF) for critically ill cancer patients.Methods We developed six clinical questions using the PICO (Population, Intervention, Comparison, and Outcome) principle in diagnosis and treatment for critical ill cancer patients with ARF. Based on literature searching and meta-analyses, recommendations were devised. The GRADE (Grading of Recommendation Assessment, Development and Evaluation) method was applied to each question to reach consensus in the expert panel. Results The panel makes strong recommendations in favor of (1) metagenomic next-generation sequencing (mNGS) tests may aid clinicians in rapid diagnosis in critically ill cancer patients suspected of pulmonary infections; (2) extracorporeal membrane oxygenation (ECMO) therapy should not be used as a routine rescue therapy for acute respiratory distress syndrome in critically ill cancer patients but may benefit highly selected patients after multi-disciplinary consultations; (3) cancer patients who have received immune checkpoint inhibitor therapy have an increased incidence of pneumonitis compared with standard chemotherapy; (4) critically ill cancer patients who are on invasive mechanical ventilation and estimated to be extubated after 14 days may benefit from early tracheotomy; and (5) high-flow nasal oxygen and noninvasive ventilation therapy can be used as a first-line oxygen strategy for critically ill cancer patients with ARFs. A weak recommendation is: (6) for critically ill cancer patients with ARF caused by tumor compression, urgent chemotherapy may be considered as a rescue therapy only in patients determined to be potentially sensitive to the anticancer therapy after multidisciplinary consultations. Conclusions The recommendations based on the available evidence can guide diagnosis and treatment in critically ill cancer patients with acute respiratory failure and improve outcomes.

La estancia hospi talaria fue 12,1 ± 7 d (14 ± 9 en supervivientes y 5,7 ± 3 en pacientes fallecidos). La gasometría arterial al ingreso reveló PaCO2: 52,7 ± 13,7 mmHg; PaO2: 72,2 ± 16,2 mmHg y pH de 7,36 ± 0,08. Se halló pH < 7,35 en el 18,6% y PaCO2 > 45 en el 57,4%. La PaCO2 al alta fue menor (46,1 ± 4,6; p > 0,05). El modo ST se utilizó en 34 (79%) pacientes. El período de ventilación fue 12,7 ± 10,2 días con uso de 6,9 ± 3,1 h/d. Un tercio recibió cuidados paliativos (13,9% de mortalidad). Tres pacientes (7%) fueron transferidos a la unidad de cuidados intensivos por deterioro clínico y treinta y cinco egresaron con ventilación crónica (94,6%). Conclusiones: Hubo escasas transferencias a la unidad de cuidados intensivos. La mortalidad hospitalaria fue baja y los que fallecieron tenían instrucciones anticipadas.

Introduction: Clinical experience has allowed the use of non-invasive ventilation out side the acute-care setting. We describe the clinical profile and evolution of patients who received non-invasive ventilation in a regular ward. Materials and methods: Retrospective study in patients with ventilatory support for one year in a general hospital. Results: Non-invasive ventilation was delivered to 43 patients, 67.4% of which had hy percapnia. The male/female ratio was 1:1. Age and BMI (Body Mass Index) were 68.3 ± 12.4 years and 30.1 ± 12.3 kg/m2, and the main diagnoses were chronic obstructive pulmonary disease, neuromuscular disease and obesity-hypoventilation. One third of patients began non-invasive ventilation in the Intensive Care Unit, and two thirds had been using non-invasive ventilation at their homes before being admitted with exacerba tion of chronic obstructive pulmonary disease (39.5%) or disease progression (14%). Hospital length of stay was 12.1 ± 7 d (14 ± 9 in survivors and 5.7 ± 3 in deceased patients). Arterial blood gas analysis on admission showed: PaCO2 (partial pressure of arterial carbon dioxide), 52.7 ± 13.7 mmHg; PaO2 (partial pressure of arterial oxygen), 72.2 ± 16.2 mmHg, and pH, 7.36 ± 0.08. A pH level < 7.35 was found in 18.6%, and PaCO2 > 45 in 57.4%. PaCO2 values upon discharge were lower (46.1 ± 4.6; p > 0.05). The ST (spontaneous-timed) mode was used in 34 patients (79%). The ventilation period was 12.7 ± 10.2 days, using 6.9 ± 3.1 h/d. One third of patients received palliative care (13.9% of mortality). Three patients (7%) were transferred to the Intensive Care Unit due to clinical decline, and thirty-five were discharged with chronic ventilation (94.6%). Conclusions: there were few referrals to the Intensive Care Unit. Hospital mortality was low, and patients who died had advance directives.

Introducción: La ventilación mecánica no invasiva es una alternativa ventilatoria para los casos con COVID-19. Objetivo: Describir las características y la evolución de la ventilación mecánica no invasiva en los pacientes egresados en el Centro Provisional para pacientes moderados con COVID-19 en Figali, Panamá. Métodos: Estudio descriptivo, retrospectivo, longitudinal. Incluyó a todos los pacientes adultos egresados entre junio y julio del 2021 que recibieron ventilación mecánica no invasiva. Se utilizó un cuestionario cuya fuente primaria fue la historia clínica individual digital. Se emplearon técnicas de la estadística descriptiva. Resultados: De 217 ingresados con COVID-19 moderado, 78 (35,9 por ciento) necesitaron ventilación mecánica no invasiva, iniciada con media al noveno día de síntomas y segundo después del ingreso. De estos, el 62,8 por ciento eran obesos y el 29,5 por ciento hipertensos. En el 56,4 por ciento, la frecuencia respiratoria ≥30 y la disminución de la razón PaO2/FiO2 fueron los indicadores principales que decidieron el inicio de la VMNI. Del total de ventilados, el 62,8 por ciento tuvo un síndrome de distrés respiratorio agudo moderado-grave y esto se relacionó con el fracaso de la ventilación. La ventilación fue exitosa en el 65,4 por ciento. La razón PaO2/FiO2 <150 (62,9 por ciento), la frecuencia respiratoria ≥30 (55,6 por cientpo y el agotamiento físico (51,85 por ciento), indicaron la falla de la ventilación. Conclusiones: La ventilación mecánica no invasiva es un proceder efectivo en pacientes con COVID-19 y distrés respiratorio moderado o severo; aunque su éxito se relaciona con las formas menos graves. La PaO2/FiO2 baja junto a la clínica, fueron indicadores clave para evaluar inicio, éxito o fracaso de la ventilación mecánica no invasiva; no así los valores de PaO2, PaCO2 y SpO2(AU)

Introduction: Non-invasive mechanical ventilation is a ventilatory alternative for COVID-19 cases. Objective: To describe the characteristics and evolution of non-invasive mechanical ventilation (NIMV) in patients discharged from Provisional Center for moderate COVID-19 patients in Figali, Panama. Methods: A descriptive, retrospective, longitudinal stu was carried out in all adult patients discharged from June to July 2021 and who received non-invasive mechanical ventilation. A questionnaire was used using the digital individual medical record as primary source. Descriptive statistics techniques were used. Results: 35.9percent of the patients (78/217) who were admitted required non-invasive mechanical ventilation on the ninth day of symptoms and the second day after admission. 62.8percent (49/78) were obese and 29.5percent (23/78) hypertensive. The respiratory rate ≥30 and the decrease in the PaO2/FiO2 ratio decided the begining of non-invasive mechanical ventilation in 56.4percent (78/217) of those admitted. 62.8percent (49/78) had moderate-severe acute respiratory distress syndrome, and the severity was related to ventilation failure out of the total number of ventilated patients. Ventilation was successful in 65.4percent (51/78). PaO2/FiO2 <150 (62.9percent), respiratory rate ≥30 (55.6percent) and physical exhaustion (51.85percent) decided ventilation failure. Conclusions: Non-invasive mechanical ventilation is an effective procedure in COVID-19 patients and moderate or severe respiratory distress; although its success is related to the less severe forms. Low PaO2/FiO2, together with symptoms, were key indicators to assess the begining, success or failure of NIMV; not so the values of PaO2, PaCO2 and SpO2(AU)

Introducción: Múltiples han sido las muertes y contagios por el nuevo coronavirus. En medio de este contexto el contagio de la enfermedad en pacientes embarazadas ha sido bien documentado. Objetivo: Presentar los eventos ocurridos en embarazadas para transmitir la experiencia a quienes tratan estas pacientes. Presentación del caso: Se expone el caso de una gestante de 24 años, obesa, con embarazo de 25 semanas. Fue ingresada con neumonía por COVID-19 y evolución hacia la insuficiencia respiratoria grave que fallece durante la cesárea. Se recibió en el quirófano con hipoxemia e hipercapnia, taquicardia, cianosis, oliguria y ventilada a presión positiva con oxígeno al 100 %. Se conduce con ketamina, fentanilo y rocuronio. A los 35 min, y posterior a la histerotomía, presentó bradicardia progresiva, por lo que se inicia compresiones torácicas externas y tratamiento farmacológico. Se recuperó el ritmo sinusal a los 12 min, pero recidiva la parada en asistolia a los 20 min, con cianosis en esclavina. Se implementó compresiones y administración de epinefrina hasta fallecer 30 min después por no recuperación de ritmo y signos ciertos de la muerte. Conclusiones: La atención multidisciplinaria mejora las condiciones de tratamiento en todas las etapas. El manejo anestésico individualizado ofrece una estrategia invaluable en casos como estos, independientemente del resultado. El tromboembolismo pulmonar en la gestante es un riesgo latente y asociado a la COVID-19, incrementa, exponencialmente, su letalidad.

Introduction: Multiple deaths and infections due to the new coronavirus have occurred. In the midst of this context, the spread of the disease in pregnant patients has been well documented. Objective: Present the events that occurred in pregnant women, in order to share the experience with those who treat these patients. Presentation of the case: The case of a 24-year-old pregnant woman, obese, with a pregnancy of 25 weeks is presented. She was admitted with COVID-19 pneumonia and evolution towards severe respiratory failure led to her death during cesarean section. She was received in the operating room with hypoxemia and hypercapnia, tachycardia, cyanosis, oliguria and ventilated at positive pressure with 100% oxygen. She was treated with ketamine, fentanyl and rocuronium. At 35 min, and after hysterotomy, she presented progressive bradycardia, so external chest compressions and pharmacological treatment were initiated. The sinus rhythm was recovered at 12 min, but the asystole stop relapsed at 20 min, with cyanosis. Compressions and administration of epinephrine were implemented until death 30 minutes later due to non-recovery of rhythm and certain signs of death. Conclusions: Multidisciplinary care improves treatment conditions at all stages. Individualized anesthetic management offers an invaluable strategy in cases like these, regardless of the outcome. Pulmonary thromboembolism in pregnant women is a latent risk associated with COVID-19, exponentially increasing its lethality.

Caracterización clínica de los pacientes con COVID-19 moderado / Clinical characterization of patients with moderate COVID-19

Introducción: En Panamá, para asumir la masiva demanda de casos con COVID-19, fueron creados centros temporales para atención médica en algunos establecimientos públicos. Objetivo: Caracterizar clínicamente a pacientes ingresados con COVID-19 moderado. Métodos: Estudio descriptivo, ambispectivo, de serie de casos, realizado entre febrero y abril del 2021. Incluyó todos los ingresos en los 5 primeros meses del Centro de Atención Integral para Casos Moderados por COVID-19 en Figali. Se diseñó un cuestionario para cada paciente con datos recogidos de las historias clínicas individuales electrónicas. Resultados: De 628 pacientes ingresados, el 58,1 por ciento eran hombres y 41,6 por ciento del grupo etario de ≥ 60 años. El 54,94 por ciento ingresó luego de 7 días de síntomas, procedentes principalmente de hoteles de aislamiento (39,65 por ciento) y hospitales (26,43 por ciento). Los síntomas más frecuentes fueron la tos, disnea, fiebre y debilidad. El 84,39 por ciento fueron clasificados como COVID-19 moderados. El 51,75 por ciento requirió del ingreso en la Unidad de Cuidados Respiratorios Especiales y de estos el 3,82 por ciento necesitó ventilación mecánica invasiva. El 67,70 por ciento fue dado de alta al hogar y 14,59 por ciento fue transferido a hospitales de tercer nivel luego de la intubación orotraqueal. Conclusiones: El Centro-Figali brindó atención médica a pacientes con COVID-19 moderados, severos y críticos. Prevalecieron los síntomas generales y respiratorios altos, que se intensificaron en la fase pulmonar de la enfermedad y motivaron el ingreso. Entre los hombres, adultos mayores y pacientes con enfermedades crónicas no transmisibles estuvieron la mayoría de los ingresados y fallecidos(AU)

Introduction: In Panama, temporary centers for medical care were created in some public establishments to meet the massive demand for cases with COVID-19. Objective: To clinically describe hospitalized patients with moderate COVID-19. Methods: A descriptive, ambispective, case series study was conducted from February to April 2021. It included all admissions in the first 5 months of the Comprehensive Care Center for Moderate Cases due to COVID-19 in Figali. A questionnaire was designed for each patient with data collected from individual electronic medical records. Results: Out of 628 admitted patients, 58.1 percent were men and 41.6 percent were in the age group ≥60 years. 54.94 percent were admitted after 7 days of symptoms, mainly from isolation hotels (39.65 percent) and hospitals (26.43 percent). The most frequent symptoms were cough, dyspnea, fever and weakness. 84.39 percent were classified as moderate COVID-19. 51.75 percent required admission to the Special Respiratory Care Unit, and out of these 3.82 percent required invasive mechanical ventilation. 67.70 percent were discharged and 14.59 percent were transferred to third level hospitals after orotracheal intubation. Conclusions: Centro Figali provided medical care to patients with moderate, severe and critical COVID-19. General and upper respiratory symptoms prevailed, which intensified in the pulmonary phase of the disease and led to admission. Among men, older adults and patients with chronic non-communicable diseases were the majority of those admitted and deceased(AU)

Posición prono en embarazada con neumonía grave por COVID-19 / Prone position in pregnant woman with severe COVID-19 pneumonia

Resumen Se han comunicado buenos resultados clínicos al poner en posición prono a pacientes con Síndrome de Distrés Respiratorio Agudo por COVID-19. Objetivo: Describir la maniobra prono, sus resultados clínicos y cuidados asociados, en una mujer de 34 años de edad con 26 semanas de embarazo, que estaba en ventilación mecánica, por un cuadro clínico de neumonía multifocal por COVID-19. Se realizó maniobra prono lateralizada hacia izquierda, en tres etapas, preparación, ejecución y evaluación. Luego de 62 h de prono, se observó una recuperación favorable de la gestante: la relación PaO2/FiO2 aumentó de 151 a 368 mmHg, y disminuyó el compromiso radiológico pulmonar, sin que se detectaran complicaciones fetales. Conclusiones: Esta maniobra que puede beneficiar a pacientes con insuficiencia respiratoria grave, en embarazadas debe ser una técnica protocolizada, con equipos de trabajo experimentados e implementación adecuada.

Good clinical results have been reported when placing patients with acute respiratory distress syndrome due to COVID-19 in a prone position. Objective: To describe the prone maneuver, its clinical results and associated care in a 34-year-old woman with 26 weeks of pregnancy, who was on mechanical ventilation, due to a clinical picture of COVID-19 multifocal pneumonia. Lateralized prone maneuver was carried out to the left, in three stages, preparation, execution and evaluation. After 62 hours of prone, a favorable recovery of the pregnant woman was observed: PaO2/FiO2 ratio increased from 151 to 368 mmHg, and the pulmonary radiological compromise decreased, without fetal complications being detected. Conclusions: This maneuver that might benefit patients with severe respiratory failure, in pregnant women should be a protocolized technique, with experienced work teams and adequate implementation.
