Algoritmo diagnóstico y terapéutico de las lesiones esplácnicas provocadas durante la inserción de sondas pleurales / Diagnostic and Therapeutic Algorithm for Splanchnic Injuries Caused during Chest Tube Insertions

Introducción: La colocación de sondas pleurales es un procedimiento quirúrgico frecuente que puede tener graves complicaciones, las cuales dependen en la mayoría de los casos de la experiencia del operador, el tamaño del tubo y el uso de imágenes para guiar la inserción. Objetivo: Describir las principales lesiones esplácnicas provocadas durante la inserción de sondas pleurales y presentar algoritmos para el diagnóstico precoz y el tratamiento oportuno de estas iatrogenias. Métodos: Se realizó una revisión descriptiva narrativa durante el primer trimestre del año 2023. Se utilizaron las bases de datos electrónicas PubMed, LILACS, EBSCO y Cochrane. Se revisaron artículos publicados desde 1984 hasta el 2022. Se procuró que la mayoría de la información se enmarcara en un período no mayor de 10 años de antigüedad. Desarrollo: De las lesiones esplácnicas de la cavidad torácica, la de pulmón es la más frecuente y puede conducir a sangrado o fuga aérea persistente. Las lesiones vasculares son graves y pueden provocar la muerte si no se toman las medidas pertinentes. Se han descrito lesiones de órganos huecos de la cavidad abdominal que suelen ser parte de una hernia diafragmática. Dentro de las lesiones esplácnicas en el abdomen más frecuentes están la hepática y la esplénica. Conclusiones: Estas lesiones son prevenibles y se debe tener en cuenta su mecanismo de producción para evitarlas. Para este fin recomendamos una selección cuidadosa del sitio de inserción, realizar una confirmación adecuada de la posición de la sonda, manipularla cuidadosamente y monitorear constantemente al paciente(AU)

Introduction: Chest tube insertion is a frequent surgical procedure that can have serious complications, which depend mostly on the practitioner's experience, the tube's size and the use of imaging to guide the insertion. Objective: To describe the main splanchnic injuries caused during chest tube insertion, as well as to present algorithms for early diagnosis and timely treatment of these types of iatrogeny. Methods: A descriptive narrative review was performed during the first quarter of the year 2023. The electronic databases PubMed, LILACS, EBSCO and Cochrane were used. Articles published from 1984 to 2022 were reviewed. Most of the information was secured to be framed within a period of no more than 10 years. Development: Among the splanchnic injuries within the thoracic cavity, lung injury is the most frequent and may lead to bleeding or persistent air leak. Vascular injuries are severe and can lead to death if appropriate measures are not taken. Injuries to hollow organs of the abdominal cavity have been described to be usually part of a diaphragmatic hernia. Among the most frequent splanchnic lesions within the abdomen are the hepatic and splenic injuries. Conclusions: These lesions are preventable and their mechanism of production should be taken into account in order to avoid them. To achieve this, we recommend that the insertion site be carefully selected and that the tube's position be adequately confirmed, as well as the careful handling of the tube and the constant monitoring of the patient(AU)

Pleural Empyema in Six Horses: A Retrospective Case Series.

The clinical findings of pleural empyema in six horses were retrospectively studied using epidemiological, clinical pathology, microbiological, ultrasound, and post-mortem data. The clinical findings included tachycardia (n = 3/6), tachypnea (n = 6/6), cyanotic mucosa (n = 2/6), hyperthermia (n = 4/6), inspiratory or mixed dyspnea (n = 6/6), presence of fluid and/or pleural rubbing (n = 2/6) and coarse crackling on auscultation (n = 4/6). Horses demonstrated leukocytosis (16.22 × 103/µL) with neutrophilia (12.32 × 103/µL) and hyperfibrinogenemia (633.33 mg/dL) and an increase in urea (69.80 mg/kg) and globulins (5.22 g/dL). The pleural fluid exhibited exudate (n = 5/6). The pathogens isolated from transtracheal wash (TTW) and/or pleural effusion included Aspergillus fumigatus, Enterobacter cloacae, alpha and beta hemolytic Streptococcus, Pseudomonas aeruginosa, Salmonella sp., Streptococcus equi subsp. zooepidemicus, and beta hemolytic Staphylococcus. The in vitro tests of microbial sensitivity of the isolates revealed that ceftiofur (5/6) and penicillin (3/6) were the most effective drugs. The fatality rate was 83% (5/6). The main post-mortem finding was the presence of fibrin in the pleural cavity with adhesion between the parietal and visceral pleura. These results show that pleural empyema is a complex disease pathophysiology that is refractory to conventional treatment.

Management of pneumothorax with 8.3-French Pigtail Catheter: description of the ultrasound-guided technique and case series.

Spontaneous and traumatic pneumothorax are most often treated with chest tube (CT) thoracostomy. However, it appears that small-bore drainage systems have similar success rates with lower complications, pain, and discomfort for the patient. We present the description of the ultrasound-guided technique for pneumothorax drainage with an 8.3-French pigtail catheter (PC) in a case series of 10 patients.

Challenging chest drainage: a case report / Drenaje torácico desafiante: reporte de un caso

Introduction. Chest trauma is one of the most common causes of death corresponding to 20 to 25 % of cases. The majority of the patients (85%), can be managed with only a tube thoracostomy. Our objective by presenting this case report is to provide an example of how to manage a challenging chest tube thoracostomy in a patient with cardiac hernia diagnosed in the preoperative phase, based on signs of computed tomography. Case report. A 45-year-old male presented to our emergency department who fell from a light pole 7 meters high. He fell to the ground on his back. Physical examination revealed a huge subcutaneous emphysema on his entire anterior chest wall and presented no sensitivity or movements below the navel line. After the initial assessment and management care, the patient improved. As the patient stabilized we decided to go to CT. The scan revealed pericardial rupture with only the right pericardial circumference intact, the heart herniated into the left pleural space, bilateral pneumothorax, small right hemothorax and a relevant subcutaneous emphysema surrounding the chest. We decided to perform the blunt dissection technique to insert chest tubes bilaterally because of safety. After performed it the patient was transferred to cardiothoracic department. Discussion. There is a variety of techniques to perform tube thoracostomy but the blunt dissection remain the safer, especially when we are facing an anatomic distortion of the heart. Conclusion. We present a case report of a challenging thoracic drainage performed in a patient with traumatic cardiac hernia, which procedure was successful

Introducción. El traumatismo torácico es una de las causas más comunes de muerte y corresponde al 20 a 25 % de los casos. La mayoría de los pacientes (85 %) pueden tratarse solo con toracostomía. Nuestro objetivo al presentar este informe de caso es proporcionar un ejemplo de cómo manejar una toracostomía desafiante en un paciente con hernia cardíaca, diagnosticada en la fase preoperatoria, basada en signos de tomografía computarizada. Presentación del caso. Paciente masculino de 45 años que ingresa a nuestro departamento de emergencias luego de caída de 7 metros de altura (poste de luz), cayendo de espaldas al suelo. El examen físico reveló un enfisema subcutáneo importante en todo el tórax anterior y sin sensibilidad ni movimientos debajo de la línea del ombligo. Después de la evaluación y atención inicial el paciente mejoró y se decidió realizar una tomografía computarizada que reveló la rotura pericárdica, con solo la circunferencia pericárdica derecha intacta, el corazón herniado en el espacio pleural izquierdo, neumotórax bilateral, pequeño hemotórax en el lado derecho y enfisema subcutáneo rodeando completamente el tórax. Se escogió una técnica de disección roma para insertar el tubo torácico en ambos hemitórax, debido a su mayor seguridad. Posteriormente, el paciente fue trasladado al departamento de cirugía cardiotorácica. Discusión. Existe una variedad de técnicas para realizar una toracostomía con sonda, pero la disección roma sigue siendo la más segura, especialmente cuando enfrentamos una distorsión anatómica del corazón. Conclusión. Presentamos el caso de un drenaje torácico desafiante practicado a un paciente con hernia cardíaca traumática, con éxito.

Conservative management in iatrogenic splenic trauma after chest tube insertion.

Insertar un tubo torácico es una maniobra terapéutica de gran valor, pero no exenta de complicaciones. Nuestro objetivo es poner de manifiesto una nueva opción de tratamiento mediante técnicas radiológicas intervencionistas que eviten los riesgos de una cirugía en pacientes seleccionados. Presentamos el caso de un paciente pluripatológico con diagnóstico de empiema pulmonar izquierdo al que de manera accidental se le insertó un tubo torácico en el polo superior esplénico. La comorbilidad del paciente y la presencia de estabilidad hemodinámica abogaron por un tratamiento conservador mediante cateterización esplénica supraselectiva e introducción de cola quirúrgica en la retirada del tubo.

Inserting a chest tube is a therapeutic tool of great value not without complications. Our objective is to highlight a new treatment option using interventional radiological techniques that avoid the risks of surgery in selected patients. We present the case of a multi-pathological patient with a diagnosis of left pulmonary empyema who accidentally inserted a chest tube into the splenic superior pole. The comorbidities of the patient and the presence of hemodynamic stability advocated conservative treatment through supraselective splenic catheterization and the introduction of surgical glue in the withdrawal of the tube.

Videothoracoscopic surgery before and after chest tube drainage for children with complicated parapneumonic effusion / Cirurgia torácica vídeoassistida antes e depois de drenagem torácica em crianças com derrame parapneumônico complicado

Abstract Objectives To evaluate the effectiveness of videothoracoscopic surgery in the treatment of complicated parapneumonic pleural effusion and to determine whether there is a difference in the videothoracoscopic surgery outcome before or after the chest tube drainage. Methods The medical records of 79 children (mean age 35 months) undergoing videothoracoscopic surgery from January 2000 to December 2011 were retrospectively reviewed. The same treatment algorithm was used in the management of all patients. Patients were divided into two groups: in group 1, videothoracoscopic surgery was performed as the initial procedure; in group 2, videothoracoscopic surgery was performed after previous chest tube drainage. Results Videothoracoscopic surgery was effective in 73 children (92.4%); the other six (7.6%) needed another procedure. Sixty patients (75.9%) were submitted directly to videothoracoscopic surgery (group 1) and 19 (24%) primarily underwent chest tube drainage (group 2). Primary videothoracoscopic surgery was associated with a decrease of hospital stay (p = 0.05), time to resolution (p = 0.024), and time with a chest tube (p < 0.001). However, there was no difference between the groups regarding the time until fever resolution, time with a chest tube, and the hospital stay after videothoracoscopic surgery. No differences were observed between groups regarding the need for further surgery and the presence of complications. Conclusions Videothoracoscopic surgery is a highly effective procedure for treating children with complicated parapneumonic pleural effusion. When videothoracoscopic surgery is indicated in the presence of loculations (stage II or fibrinopurulent), no difference were observed in time of clinical improvement and hospital stay among the patients with or without chest tube drainage before videothoracoscopic surgery.

Resumo Objetivos Avaliar a eficácia da cirurgia torácica videoassistida no tratamento de derrame pleural parapneumônico complicado e determinar se há diferença no resultado da cirurgia torácica videoassistida realizada antes ou depois da drenagem torácica. Métodos Analisamos retrospectivamente prontuários médicos de 79 crianças (idade média de 35 meses) submetidas a cirurgia torácica videoassistida de janeiro de 2000 a dezembro de 2011. O mesmo algoritmo de tratamento foi utilizado no manejo de todos os pacientes. Os pacientes foram divididos em dois grupos: o Grupo 1 foi submetido a cirurgia torácica videoassistida como procedimento inicial; o Grupo 2 foi submetido a cirurgia torácica videoassistida após drenagem torácica prévia. Resultados A cirurgia torácica videoassistida foi eficaz em 73 crianças (92,4%); as outras seis (7,6%) necessitaram outro procedimento. Sessenta pacientes (75,9%) foram diretamente submetidos a cirurgia torácica videoassistida (Grupo 1) e 19 (24%) foram primeiramente submetidos a drenagem torácica (Grupo 2). A cirurgia torácica videoassistida primária foi associada à redução do tempo de internação (p = 0,05), do tempo para resolução (p = 0,024) e do tempo com o tubo torácico (p < 0,001). Contudo, não houve diferença entre os grupos a respeito do tempo até que não tivessem mais febre, do tempo com o tubo torácico e do tempo de internação após a cirurgia torácica videoassistida. Não foram observadas diferenças entre os grupos com relação à necessidade de cirurgia adicional e à presença de complicações. Conclusões A cirurgia torácica videoassistida é um procedimento altamente eficaz para tratar crianças com derrame pleural parapneumônico complicado. Quando a cirurgia torácica vídeoassistida é indicada na presença de loculações (fase II ou fibrinopurulenta) não há diferença no tempo de melhora clínica e no tempo de internação entre os pacientes com ou sem drenagem torácica antes da cirurgia torácica videoassistida.

Cervical and transdiaphragmatic paraxiphoid thoracoscopy in dogs: evaluation of respiratory response and blood pressure / Toracoscopias cervical e paraxifóide transdiafragmática em cães: aplicação de técnica e avaliação da resposta respiratória e pressão sanguínea

This study evaluated the cervical and transdiaphragmatic thoracoscopic approaches regarding their implementation, intrathoracic evaluation and application of a chest tube, using the treatment of pneumothorax as an experimental model. After injection of 20ml kg-1 of air per hemithorax, thoracoscopy was made by transdiaphragmatic paraxiphoid or cervical positions. After cavity examination, a thoracic drain was inserted using the surgical site to drain the pneumothorax. The cardiorespiratory function and arterial blood gas were measured during time of evaluation. The cavity examination allowed visualizing the aspect and function of intrathoracic structures. There were no significant differences between the two approaches when comparing the measurements made in each period evaluated. Both enabled intracavitary exploration and application of thoracic drain. Cervical access shows viability, but resulted in the death of two patients, and it not recommended as a substitute for the latter in the insertion of thoracic drains in dogs.(AU)

Este estudo avaliou os acessos toracoscópicos cervical e paraxifóide em relação à sua aplicação, avaliação intratorácica e colocação de dreno torácico, utilizando o tratamento de pneumotórax como modelo experimental. Após a injeção de 20ml kg-1 de ar por hemitórax, a toracoscopia foi realizada pelas técnicas cervical ou paraxifóide transdiafragmática. Após a exploração da cavidade, foi inserido um dreno torácico utilizando o acesso cirúrgico para drenar o pneumotórax. A função cardiorrespiratória e a gasometria arterial foram aferidas durante o tempo de avaliação. A exploração da cavidade permitiu visualização do aspecto e função das estruturas intratorácicas. Não houve diferenças significativas entre os dois acessos quanto aos dados aferidos em cada período de avaliação. Ambos permitiram exploração intracavitária e aplicação do dreno torácico. O acesso cervical demonstra viabilidade, porém resultou na morte de dois pacientes, e não é recomendado como substituta à paraxifóide transdiafragmática para a aplicação de drenos torácicos em cães.(AU)

Retiro de la sonda de pleurostomia con succión negativa continua versus instalación de sonda con sello de agua, en cirugía cardiovascular cerrada en niños / Withdrawal of chest tubes without water seal vs. negative continuous suction after closed cardiovascular surgery procedures in children

Objetivo: identificar la frecuencia y tipo de complicaciones, así como tiempo de estancia hospitalaria, en niños con cirugía cardiovascular a quienes se les dejó sonda de pleurostomía con sello de agua en el posoperatorio y a quienes se les retiró bajo succión continua al término de la toracotomía. Material y métodos: se realizó estudio descriptivo, comparativo y retrospectivo en el Hospital de Pediatría, Centro Médico Nacional Siglo XXI. Se estudiaron 88 niños sin sonda (grupo I) y 42 con sonda de pleurostomía (grupo II), sometidos a cirugía cardiovascular cerrada. Resultados: la frecuencia de complicaciones fue de 27.3 y 59.5 % en los grupos I y II. El enfisema subcutáneo tuvo una frecuencia de 13.6 % en el grupo I y de 45.2 % en el II (p = 0.0001); el neumotórax de 13.6 versus 28.6 % (p = 0.04) y el quilotórax de 2.3 versus 2.4 % (p = 1.0). La mediana del tiempo de estancia hospitalaria fue de tres y seis días en los grupos I y II, respectivamente (p = 0.0001). Conclusiones: en algunos tipos de cirugía cardiovascular cerrada en niños, el retiro de la sonda al término de la pleurostomía previa succión negativa continua, puede disminuir la frecuencia de neumotórax y enfisema subcutáneo y la estancia intrahospitalaria, en comparación cuando se deja la sonda con sello de agua en el posoperatorio.

BACKGROUND: We undertook this study to compare the frequency and type of complications, as well as the length of hospital stay, in children who underwent closed cardiovascular surgery with chest tube drainage during the postsurgical period with children in whom the drainage was withdrawn with continuous suction, once thoracotomy was completed. METHODS: A retrospective, descriptive and analytic study was performed at the IMSS Hospital de Pediatria, located at the XXI Century National Medical Center in Mexico City. Eighty eight children who underwent closed cardiovascular surgery (Group I) without chest tubes and 42 with chest tubes (Group II) were studied. RESULTS: In Group I the frequency of complications was 27.3% and in group II 59.5%. Complications were as follows: subcutaneous emphysema was seen in 13.6% (n=12) of group I and in 45.2% (n=19) of group II (p=0.0001); pneumothorax in 13.6% (n=12) vs. 28.6% (n=12), p=0.04; and chylothorax in 2.3% (n=2) vs. 2.4% (n=1), p=1.0, respectively. The median time of hospital stay in group I was 3 days and in group II was 6 days (p=0.0001). CONCLUSIONS: In children, in some closed cardiovascular surgeries, withdrawal of chest tube drainage with negative suction when thoracotomy is completed may decrease the frequency of pneumothorax, subcutaneous emphysema and length of hospital stay, in comparison with patients in whom chest tube drainage is left during the postoperative period.

Utilidad de la toracotomìa digital en el traumatismo de tórax / Utility of digital thoracotomy in chest trauma

Antecedentes: la toracostomÍa para el drenaje pleural en el trauma de tórax es una inmejorable oportunidad para la exploración digital de la cavidad. Objetivos: evaluar la utilidad de la exploración digital en oportunidad del avenamiento pleural en trauma torácico. Lugar de realización: Hospital de Urgencias de Córdoba. Diseño: estudio prospectivo. Pacientes y métodos: se evaluaron los pacientes con trauma cerrado o penetrante de tórax por herida de arma blanca con indicación de avenamiento pleural y que fueron asistidos por un solo operador, entre ello de julio hasta el30 de diciembre de 2000. Previo a la toracostomía con tubo de 24 french al nivel del 5to espacio intercostal del lado afectado, se efectuó la exploración digital, intentando ubicar lesiones en la cavidad pleural. Resultados: se realizaron en el periodo de 6 meses 36 avenamientos pleurales, 11 por traumatismo cerrado de tórax y 25 por herida de arma blanca. Tres pacientes tuvieron hallazgos positivos en la exploración digital lo que motivo a realizar nuevos procedimientos diagnósticos o terapéuticos. Conclusión: La toracostomía digital no es considerada habitualmente como una operación formal, sino parte de una técnica, en la cual, la inserción del dedo previo a la colocación del tubo de toracostomÍa, nos permite acceder a un diagnóstico de situación en el espacio pleural, confirmar una sospecha, modificar la conducta a seguir y evitar mayor morbilidad para el paciente.

Background: thoracostomy in thoracic trauma is a good opportunity for the digital exploration of pleural cavity. Objectives: To evaluate the utility of digital exploration during chest tube insertion in thoracic trauma. Setting: Hospital de Urgencias. Córdoba. Patients and methods: patients with blunt and penetrating chest trauma by stab wound, who need chest tube insertion and treated by only one surgeon, were evaluated from July 10 to December 31st 2000. Previously to the thoracostomy with 24 French tube in 5th intercostals space, at the affected side, a digital exploration of pleural cavity was done, attempting to find intrathoracic injuries. Results: in a six months period, 36 thoracostomy tubes were placed, due thoracic trauma (11 blunt trauma and 25 penetrating. by stab wound). Three patients had positive findings in the digital exploration, which forced to do another diagnostic or therapeutic procedures...
