Caracterización de las lesiones ocasionadas en combate y su tratamiento / Characterization of injuries during combat and their treatment

Introducción. Colombia es un país que ha tenido el conflicto armado como parte de su historia. Durante más de 50 años, diferentes tipos de armas han sido empleados en la guerra interna. Desde el año 1999 hasta 2010, en el Hospital Militar Central, Bogotá, D.C., Colombia, se atendieron más de 15.000 personas heridas en combate. El objetivo de este estudio fue describir los abordajes quirúrgicos realizados para el tratamiento de lesiones generadas en combate militar, por el servicio de Cirugía general en el Hospital Militar Central, entre los años 2016 y 2021. Métodos. Se condujo un estudio observacional descriptivo de corte transversal, en donde se recolectó información de la base de datos del grupo de Trauma del Hospital Militar Central, sobre los pacientes con lesiones generadas en combate, atendidos por el servicio de cirugía general. Resultados. En total ingresaron 203 pacientes, 99 % de sexo masculino, 87 % pertenecientes al ejército. El departamento de donde más se recibieron heridos fue Arauca (20,7 %). Las armas de fuego de alta velocidad fueron los artefactos relacionados con las heridas en más de la mitad de los casos. Las intervenciones quirúrgicas más frecuentes fueron extracción de cuerpo extraño (28 %), exploración vascular (25,5 %) y toracostomía o toracoscopia (20,6 %). Conclusión. Los procedimientos quirúrgicos para el manejo del trauma militar siguen siendo variados con respecto a la ubicación y el abordaje, razón por la cual el conocimiento del cirujano general debe ser amplio, para estar capacitado para su manejo.

Introduction. Colombia is a country that has had armed conflict as part of its history. For more than 50 years, different types of weapons have been used in internal warfare. From 1999 to 2010, more than 15,000 people injured in combat were treated at the Central Military Hospital, Bogotá, D.C., Colombia. The objective of this study was to describe the surgical approaches carried out for the treatment of injuries generated in military combat, by the General Surgery service at the Central Military Hospital, between 2016 and 2021. Methods. A cross-sectional descriptive observational study was conducted, where information was collected from the database of the Trauma group of the Central Military Hospital on patients with injuries during combat treated by the General Surgery service. Results. A total of 203 patients were admitted, 99% were male, 87% belonged to the Army. The department from which the most wounded were received was Arauca (20.7%). High-velocity firearms were the injury-related weapons in more than half of the cases. The most common surgical interventions performed were foreign body extraction (28%), vascular exploration (25.5%), and thoracostomy or thoracoscopy (20.6%). Conclusion. Surgical procedures for the management of military trauma continue to be varied with respect to location and approach, which is why the general surgeon's knowledge must be extensive to be qualified for its management.

Fascitis necrosante como causa de muerte en trauma de recto. Reporte de caso / Necrotizing fasciitis as a cause of death in rectal trauma. Case report

Introducción. La perforación del recto por trauma cerrado es poco frecuente y se asocia a fracturas pélvicas. En pacientes con perforaciones de recto no traumáticas se ha reportado fascitis necrosante en miembros inferiores, en la mayoría de los casos asociada a alta mortalidad. Caso clínico. Hombre de 36 años con trauma cerrado abdomino-pélvico y perforación de recto inferior, quien recibió manejo quirúrgico mediante derivación intestinal y fijación pélvica. Evolucionó con hematoma escrotal sobreinfectado, inestabilidad hemodinámica, signos de fascitis necrosante y choque séptico 4 días posterior a su ingreso. Resultados. Se tomó muestra para cultivo del hematoma escrotal que reportó E. coli. La patología del desbridamiento escrotal informó necrosis de coagulación en toda la muestra. Conclusión. El tacto rectal debe realizarse siempre ante la presencia de enfisema subcutáneo al examen físico o en la tomografía, para un diagnóstico temprano y manejo quirúrgico multidisciplinario oportuno, según el caso. La presencia de enfisema subcutáneo debe aumentar la sospecha de perforación de recto. Hay pocos reportes de fascitis secundaria a perforación de recto por trauma cerrado, por lo que no se conoce con precisión la mortalidad asociada.

Introduction. Rectal perforation due to blunt trauma is rare and associated with pelvic fractures. Signs of necrotizing fasciitis in lower limbs have been reported in non-traumatic rectal perforations, in most cases associated with high mortality. Case report. A 36-year-old man presents blunt abdomino-pelvic trauma and perforation of the lower rectum. Surgical management by intestinal diversion and pelvic fixation is performed. 4 days after admission, evolves with over-infected scrotal hematoma, hemodynamic instability, signs of necrotizing fasciitis and septic shock. Results. A sample for culture was taken from a scrotal hematoma that reported E. coli. Pathology of scrotal debridement reported coagulation necrosis in the entire specimen. Discussion. Digital rectal examination should always be performed in the presence of subcutaneous emphysema on physical examination or CT scan for early and multidisciplinary diagnosis and surgical management as appropriate. Conclusion. The presence of subcutaneous emphysema should raise the suspicion of rectal perforation. There are few reports of rectal perforation due to blunt trauma and fasciitis, so the associated mortality is not precisely known.

Is the use of ozonated oil effective in the treatment of oral lesions? Systematic review of clinical studies / ¿Es el uso del aceite ozonizado efectivo en el tratamiento de las lesiones orales? Una revisión sistemática de estudios clínicos

Abstract The aim of this study was to perform a systematic review (SR) of the therapeutic effect of ozonated oil for oral lesions treatment. A SR was conducted according to the PRISMA guidelines. The Medline (PubMed), Embase, Cochrane Library, Scielo and LILACS were investigated, together with manual searches, to extract all publications until December 2020, including randomized and non-randomized clinical trials reporting the effects of ozonated oils on the management of oral lesions when compared with other methods. The risk of bias (RoB) of the studies included were assessed by using the RoB 2 tool and ROBINS-I. After analyzing the titles and reading the abstracts, 1932 articles were excluded; the remaining 25 passed a full-text evaluation. Ultimately, 13 articles were included in this SR. There was heterogeneity of the results regarding healing times and intervals of ozonated oil application for the treatment of each type of oral lesion, but in general, there was a shorter healing time when ozonated oil was used as therapy, and no adverse effects were reported. Despite the limited information found and the lack of rigorous methodological standards for the use of ozonated oil on oral lesions, a positive effect was suggested. The findings indicated an advantage in terms of shorter healing times when compared with other conventional treatments. No adverse effects were reported, showing safety and reliability for patient's treatment.

Resumen El objetivo de este estudio fue realizar una revisión sistemática (RS) del efecto terapéutico del aceite ozonizado sobre las lesiones orales. Se realizó una RS siguiendo las directrices PRISMA. Se realizaron búsquedas en Medline (PubMed), Embase, Cochrane Library, Scielo y LILACS, y búsquedas manuales, que abarcaron hasta diciembre de 2020, de ensayos clínicos aleatorizados y no aleatorizados que informaran sobre el efecto de los aceites ozonizados en el tratamiento de las lesiones orales en comparación con cualquier otro método. El riesgo de sesgo (RoB) de los estudios incluidos se evaluó mediante la herramienta RoB 2 y ROBINS-I. Tras analizar los títulos y leer los resúmenes, se excluyeron 1932 artículos; los 25 restantes pasaron una evaluación exhaustiva del texto completo. Finalmente, se incluyeron 13 artículos en esta RS. Hubo heterogeneidad de resultados en cuanto a los tiempos de cicatrización y los intervalos de aplicación del aceite ozonizado para el tratamiento de cada tipo de lesión oral, pero en general, hubo un menor tiempo de cicatrización cuando se utilizó el aceite ozonizado como terapia, y no se comunicaron efectos adversos. A pesar de la limitada información encontrada y de la falta de normas metodológicas rigurosas sobre el uso de aceite ozonizado en lesiones orales, se sugirió un efecto positivo del uso de aceite ozonizado para el tratamiento de lesiones orales. Los resultados indicaron una ventaja en términos de menor tiempo de curación en comparación con otros tratamientos convencionales; además, no se notificaron efectos adversos, por lo que se demostró una opción de tratamiento segura y fiable para los pacientes.

Uso de la tomografía corporal total en pacientes con heridas de arma de fuego y hemodinámicamente inestables: ¿Rompiendo paradigmas de atención inicial? / Whole-body computed tomography in hemodynamically unstable patients with gunshot wounds: A paradigm shift in trauma management?

Introducción. El objetivo del estudio fue analizar el impacto del uso de la tomografía corporal total en la evaluación de los pacientes con trauma penetrante por proyectil de arma de fuego y hemodinámicamente inestables atendidos en un centro de referencia de trauma. Métodos. Se realizó un estudio analítico, retrospectivo, con base en un subanálisis del registro de la Sociedad Panamericana de Trauma ­ Fundación Valle del Lili. Se incluyeron los pacientes con trauma penetrante por proyectil de arma de fuego atendidos entre 2018 y 2021. Se excluyeron los pacientes con trauma craneoencefálico severo, trauma leve y en condición in extremis. Resultados. Doscientos pacientes cumplieron los criterios de elegibilidad, 115 fueron estudiados con tomografía corporal total y se compararon con 85 controles. La mortalidad intrahospitalaria en el grupo de tomografía fue de 4/115 (3,5 %) vs 10/85 (12 %) en el grupo control. En el análisis multivariado se identificó que la tomografía no tenía asociación significativa con la mortalidad (aOR=0,46; IC95% 0,10-1,94). El grupo de tomografía tuvo una reducción relativa del 39 % en la frecuencia de cirugías mayores, con un efecto asociado en la disminución de la necesidad de cirugía (aOR=0,47; IC95% 0,22-0,98). Conclusiones. La tomografía corporal total fue empleada en el abordaje inicial de los pacientes con trauma penetrante por proyectil de arma de fuego y hemodinámicamente inestables. Su uso no se asoció con una mayor mortalidad, pero sí con una menor frecuencia de cirugías mayores.

Introduction. This study aims to assess the impact of whole-body computed tomography (WBCT) in the evaluation of patients with penetrating gunshot wounds (GSW) who are hemodynamically unstable and treated at a trauma referral center. Methods. An analytical, retrospective study was conducted based on a subanalysis of the Panamerican Trauma Society-FVL registry. Patients with GSW treated between 2018 and 2021 were included. Patients with severe cranioencephalic trauma, minor trauma, and those in extremis were excluded. Patients with and without WBCT were compared. The primary outcome was in-hospital mortality, and the secondary outcome was the frequency of major surgeries (thoracotomy, sternotomy, cervicotomy, and/or laparotomy) during initial care. Results. Two hundred eligible patients were included, with 115 undergoing WBCT and compared to 85 controls. In-hospital mortality in the WBCT group was 4/115 (3.5%) compared to 10/85 (12%) in the control group. Multivariate analysis showed that WBCT was not significantly associated to mortality (aOR: 0.46; 95% CI 0.10-1.94). The WBCT group had a relative reduction of 39% in the frequency of major surgeries, with an associated effect on reducing the need for surgery (aOR: 0.47; 95% CI 0.22-0.98). Conclusions. Whole-body computed tomography was employed in the initial management of patients with penetrating firearm projectile injuries and hemodynamic instability. The use of WBCT was not associated with mortality but rather with a reduction in the frequency of major surgery.

Umbral crítico de administración en pacientes con trauma severo y reanimación endovascular: ¿Un concepto útil? / Critical Administration Threshold in severe trauma patients and endovascular resuscitation: A useful concept?

Introducción. Se describe la utilidad del umbral crítico de administración (CAT por su denominación en inglés) como herramienta para la reanimación hemostática en pacientes con trauma severo y oclusión endovascular aórtica. Métodos. Revisión retrospectiva de pacientes adultos con hemorragia por trauma, con o sin oclusión endovascular aórtica (REBOA), atendidos entre enero de 2015 y junio de 2020, en un centro de trauma nivel I en Cali, Colombia. Se registraron variables demográficas, severidad del trauma, estado clínico, requerimiento transfusional, tiempo hasta CAT+ y CAT alcanzado (1, 2 ó 3). Resultados. Se incluyeron 93 pacientes, se utilizó REBOA en 36 y manejo tradicional en 57. El grupo REBOA presentó mayor volumen de sangrado (mediana de 3000 ml, RIC: 1950-3625 ml) frente al grupo control (mediana de1500 ml, RIC: 700-2975ml) (p<0,001) y mayor cantidad de glóbulos rojos transfundidos en las primeras 6 horas (mediana de 5, RIC:4-9); p=0,015 y en las primeras 24 horas (mediana de 6, RIC: 4-11); p=0,005. No hubo diferencias estadísticamente significativas en número de pacientes CAT+ entre grupos o tiempo hasta alcanzarlo. Sin embargo, el estado CAT+ durante los primeros 30 minutos de la cirugía fue mayor en grupo REBOA (24/36, 66,7 %) frente al grupo control (17/57, 29,8 %; p=0,001), teniendo este mayor tasa de mortalidad intrahospitalaria frente a los pacientes CAT-. Conclusión. El umbral crítico de administración es una herramienta útil en la reanimación hemostática de pacientes con trauma y REBOA, que podría predecir mortalidad precoz.

Introduction. The objective is to describe the utility of the Critical Administration Threshold (CAT) as a tool in hemostatic resuscitation in patients with severe trauma and REBOA. Methods. Retrospective review between January 2015 and June 2020 of adult patients with hemorrhage secondary to trauma with or without REBOA in a level I trauma center in Cali, Colombia. Demographic variables, trauma severity, clinical status, transfusion needs, time to CAT+ and number of CAT achieved (1, 2 or 3) were recorded. Results. Ninety-three patients were included, in which REBOA was used in 36 and traditional management in 57. The REBOA group had a higher bleeding volume (3000 ml), IQR: 1950-3625 ml vs the control group (1500 ml, IQR: 700-2975 ml) (p<0.001) and a higher rate of PRBC units transfused in the first 6 hours (median 5, IQR: 4-9); p=0.015 and in the first 24 hours (median 6, IQR: 4-11); p=0.005. There were no statistically significant differences in the number of CAT+ patients between groups or time to CAT+. However, CAT+ status during the first 30 minutes of surgery was higher in the REBOA Group (24/36, 66.7%) vs. the control group (17/57, 29.8%; p=0.001), having this group a higher in-hospital mortality rate vs. CAT- patients. Conclusion. CAT is a useful tool in the hemostatic resuscitation of patients with trauma and REBOA that could predict early mortality.

El verdadero origen histórico del trauma cardíaco penetrante / The true historical origin of penetrating cardiac trauma

Introducción. Los traumatismos cardíacos son lesiones graves y con elevado índice de letalidad, aspecto que influye en el interés mostrado por los lectores cada vez que aparecen reportados en publicaciones científicas. En ocasiones existe cierto grado de incongruencia a la hora de establecer el origen histórico de sucesos o eventos ocurridos y relacionados con la historia de la medicina. En el caso del trauma cardíaco penetrante han sido descritos diversos orígenes en algunos de los artículos científicos publicados, lo cual puede generar un grado de duda en los lectores. Métodos. Se realizó una revisión de la literatura, médica y no médica, para buscar información que ayudara a esclarecer el verdadero origen histórico de esta entidad. Resultados. El trauma cardíaco penetrante fue descrito por primera vez en la obra griega titulada La Ilíada, escrita por Homero en el siglo VIII A.C., y no en El papiro quirúrgico de Edwin Smith, como varios autores mencionan. Conclusiones. De todos los eventos de trauma cardíaco penetrante descritos, el más irrefutable es el narrado en el canto XIII, donde se cuenta la muerte de Alcátoo, producto de una herida cardíaca ocasionada por una lanza arrojada por Idomeneo durante una batalla

Introduction. Cardiac traumatic injuries are serious injuries with a high lethality rate, an aspect that influences the interest shown by readers each time they appear reported in scientific publications. Sometimes there is a certain degree of inconsistency when it comes to establishing the historical origin of occurrences or events related to the history of medicine. In the case of penetrating cardiac trauma, different origins have been described in some of the published scientific articles, which may generate a degree of doubt in the readers. Methods. A review of the medical and non-medical literature was carried out to seek information that would help to clarify the true historical origin of this entity. Results. Penetrating cardiac trauma was first described in a Greek work entitled The Iliad, written by Homer in the 8th century B.C., and not in The Surgical Papyrus of Edwin Smith as several authors mention. Conclusions. Of all the events of penetrating cardiac trauma described, the most irrefutable is the one narrated in canto XIII, where it recounts the death of Alcathous product of a cardiac wound caused by a spear thrown by Idomeneo during a battle.

Lesión cardíaca por arma blanca inadvertida durante la evaluación inicial en el servicio de emergencia / Missed cardiac stab injury during initial evaluation in the Emergency Department

Introducción. La incidencia reportada de traumatismo cardíaco es baja y su grado de resolución es variable, dependiendo de la causa, el mecanismo de la lesión, el lugar donde ocurra y las características del sistema sanitario. Su incidencia ha aumentado recientemente debido al incremento de los accidentes de tránsito y la violencia, predominando los traumatismos penetrantes asociados a heridas por armas cortopunzantes y de fuego. Los traumatismos cardíacos se acompañan de un alto grado de letalidad. Caso clínico. Mujer de 35 años que consultó a emergencia por trauma torácico penetrante ocasionado por arma blanca y fue intervenida de urgencia por derrame pleural izquierdo, sin mejoría hemodinámica. Fue reevaluada detectándose derrame pericárdico con taponamiento cardíaco, ocasionado por lesión cardíaca. Fue tratada quirúrgicamente con resultados satisfactorios. Resultados. Las manifestaciones clínicas en los traumatismos penetrantes generalmente son graves y fatales, pero en algunos casos puede no comprometer tanto la hemodinamia del paciente. Para consolidar el diagnóstico clínico pueden realizarse variados estudios, siendo la ecografía FAST extendida uno de los más recomendados por su elevada sensibilidad y especificidad. Dependiendo del adelanto tecnológico del centro hospitalario y la estabilidad hemodinámica del paciente, el tratamiento quirúrgico es el más indicado. Conclusión. El conocimiento del trauma cardíaco penetrante resulta de gran importancia, no solo para el médico del servicio de emergencia sino también para el médico general. Un diagnóstico rápido y acertado, unido a un manejo adecuado, pueden ser decisivos para salvar la vida del paciente.

Introduction. The reported incidence of cardiac trauma is low and its degree of resolution is variable depending on the cause, the mechanism of injury, the place where it occurs and the characteristics of the health care system. Their incidence has currently increased due to the increase in traffic accidents and violence, with a predominance of penetrating trauma associated with stab wounds and firearms. Cardiac trauma is accompanied by a high degree of lethality. Clinical case. A 35-year-old female patient, evaluated in the emergency room for penetrating thoracic trauma caused by stab wound. She underwent emergency intervention due to left pleural effusion, but without hemodynamic improvement. She was reevaluated and pericardial effusion with cardiac tamponade caused by cardiac injury was detected. She was treated surgically with satisfactory results. Results.The clinical manifestations generally described in penetrating cardiac trauma are severe and fatal, but in some cases and due to the characteristics of the injury caused, the patient's hemodynamics may not be so compromised. To consolidate the clinical diagnosis, several complementary studies can be performed, with FAST ultrasound being one of the most recommended due to its high sensitivity and specificity. Surgical treatment is still the most indicated, depending on the technological progress of the hospital and the hemodynamic stability of the patient. Conclusions.Knowledge of penetrating cardiac trauma is of great importance, not only for the emergency department physician but also for the general practitioner. A quick and accurate diagnosis, together with adequate management can be decisive in saving the patient's life.

Feasibility and safety of a new portable endoscopic system for the diagnosis and treatment of abdominal trauma in animal models / 中华消化内镜杂志

Objective:To compare the feasibility and safety of a new portable endoscopic system and the conventional endoscopic system for the detection and emergency treatment of abdominal trauma in animal models.Methods:Three healthy Bama pigs, which were fasted and water deprivation for 8 h before surgery and then underwent induction anesthesia. A layer-by-layer incision was made into the abdominal cavity of Bama pigs. An artificial pneumoperitoneum was established using a laparoscopic pneumoperitoneum machine. A bullet model was inserted into the abdominal cavity to build the bullet wound model. After the bullet model was removed, a shrapnel model was inserted into the mid-abdomen to build the shrapnel wound model. The two types of endoscopic system were used to detect, remove bullet model or shrapnel model of the three Bama pigs respectively. The procedure order of the two systems was assigned according to the random number table method. The surgical success, operation time, endoscopy pipeline patency, endoscopic operation satisfaction, adverse events and equipment defects were recorded.Results:Three surgeries were performed using the new portable endoscopic system and three other surgeries using the conventional endoscopic system, all of which were successful. The time of the new portable endoscopic system to find and remove the bullet model, and the shrapnel model were 232.33±11.68 s, 300.33±57.70 s, 170.00±44.44 s and 52.67±2.52 s, respectively. The corresponding time of the conventional endoscopic system were 232.67±21.20 s ( t=-0.054, P=0.962), 256.67±67.00 s ( t=0.880, P=0.472), 176.00±52.42 s ( t=-0.111, P=0.922), 58.67±14.84 s ( t=-0.832, P=0.493), respectively. There was no significant difference between the two systems ( P>0.05). The endoscopy tubes of the two endoscopic systems were both smooth. The operator was satisfied with the endoscopic procedures of both endoscopic systems, and no adverse event or device defect occurred. Conclusion:The portable endoscopic system proves to be safe and feasible for the diagnosis and treatment of abdominal trauma in animal models.

Objective:To investigate the resuscitation effect of sodium bicarbonate Ringer's solution on traumatic hemorrhagic shock in patients.Methods:A randomized controlled trial was conducted on 70 patients with traumatic hemorrhagic shock who were admitted to Yiwu Central Hospital between February 2021 and February 2022. The patients were randomly assigned to a control group ( n = 35) and an observation group ( n = 35) using the random number table method. Both groups received routine treatment. The control group was given adequate resuscitation by intravenous injection of a compound sodium chloride injection, while the observation group received restricted resuscitation with sodium bicarbonate Ringer's solution. Related clinical indicators, coagulation function, lactate levels, hemorheological indicators, and incidence of complications were compared between the two groups. Results:The blood oxygen saturation, shock index, pulse pressure difference, and urine output in the observation group were (76.53 ± 2.56)%, (0.43 ± 0.07), (38.56 ± 6.52) mmHg (1 mmHg = 0.133 kPa), and (35.62 ± 4.21) mL/h, respectively. These values were all superior to those in the control group [(65.32 ± 3.21)%, (1.21 ± 0.13), (23.56 ± 4.23) mmHg, (23.65 ± 5.68) mL/h, t = 16.15, 31.25, 11.42, 10.06, all P < 0.001]. The prothrombin time, fibrinogen, activated partial thromboplastin time, and thrombin time in the observation group were (17.65 ± 0.83) seconds, (1.69 ± 0.89) g/L, (39.68 ± 0.52) seconds, and (17.86 ± 0.74) seconds, respectively. These values were significantly superior to those in the control group [(14.56 ± 0.86) seconds, (1.32 ± 0.23) g/L, (35.26 ± 0.16) seconds, and (16.02 ± 0.05) seconds, t = 15.30, 2.38, 48.06, 14.68, all P < 0.05]. The lactate level in the observation group was significantly lower than that in the control group [(2.24 ± 0.53) mmol/L vs. (2.94 ± 0.78) mmol/L, t = 4.39, P < 0.05]. The platelet cohesion, red blood cell deformability, and blood viscosity in each group were significantly reduced, and these indices in the observation group were superior to those in the control group ( t = 13.71, 5.64, 5.67, all P < 0.001). The incidence of complications in the observation group was significantly lower than that in the control group (8.6% (3/35) vs. 60.0% (21/35), χ2 = 10.08, P < 0.05). Conclusion:Restricted resuscitation with sodium bicarbonate Ringer's solution can improve clinical indicators, coagulation function, and lactate levels in patients with traumatic hemorrhagic shock.

Objective:To investigate the clinical effect of preemptive analgesia with pentazocine on perioperative pain management in partial splenectomy.Methods:A total of 100 patients with traumatic splenic rupture who underwent partial splenectomy at Yiwu Central Hospital between October 2019 and November 2021 were randomly assigned to either the control group or the study group, with 50 patients in each group using the random number table method. Both groups received patient-controlled analgesia postoperatively. Additionally, the study group received intravenous pentazocine administration before surgery. The amount of anesthetic used during surgery, postoperative anesthesia recovery indices, postoperative pain response, serum inflammatory factor levels, and the number of effective patient-controlled analgesia pump presses within 48 hours postoperatively were recorded and evaluated. Any adverse drug reactions were also monitored.Results:The dosages of propofol [(462.24 ± 27.13) mg] and remifentanil [(365.98 ± 26.78) μg] in the study group were significantly lower than those in the control group [(511.82 ± 26.32) mg, (406.86 ± 26.08) μg, t = 14.49, 12.63, both P < 0.001). The recovery time of spontaneous breathing [(6.86 ± 0.97) minutes], anesthesia recovery time [(13.24 ± 0.82) minutes] and extubation time [(17.14 ± 1.07) minutes] were significantly shorter than those in the control group [(7.62 ± 0.90) minutes, (14.32 ± 0.84) minutes, (18.22 ± 1.06) minutes, t = 5.80, 8.58, 6.93, all P < 0.001]. The Visual Analogue Scale (VAS) scores in the study group were significantly lower than those in the control group at 24 and 48 hours after surgery, both in resting and coughing state ( t = 7.82, 9.31, 4.95, 8.47, all P < 0.001). The serum levels of tumor necrosis factor-alpha, interleukin-1, and interleukin-6 were significantly lower in the study group than in the control group ( t = 21.53, 25.61, 18.45, 16.90, 17.33, 14.86, all P < 0.001), while the serum level of interleukin-10 was significantly higher in the study group than in the control group ( t = -20.85, -19.61, both P < 0.001). The number of effective patient-controlled pump analgesia presses within 48 hours postoperatively in the study group [(6.24 ± 1.17) times] was significantly lower than that in the control group [(10.26 ± 1.34) times, t = 12.95, P < 0.05). In addition, the overall incidence of adverse drug reactions in the study group [4.00% (2/50)] was significantly lower than that in the control group [18.00% (9/50), χ2 = 5.01, P < 0.05]. Conclusion:Preemptive analgesia with pentazocine for patients undergoing partial splenectomy can effectively reduce the dosage of anesthetics during surgery and the dosage of analgesics after surgery, enhance the recovery from postoperative anesthesia, suppress postoperative inflammatory reactions, alleviate pain responses, and minimize the risk of adverse drug reactions.

Effect of recombinant bovine basic fibroblast growth factor gel combined with silver ion dressing on the donor site in patients with hand trauma undergoing skin grafting / 中国基层医药

Objective:To investigate the efficacy of combined repair therapy using recombinant bovine basic fibroblast growth factor (R-bFGF) gel and silver ion dressing on the donor site of patients with hand trauma undergoing skin grafting.Methods:Eighty patients with hand trauma who underwent skin grafting at Lishui Central Hospital between October 2020 and October 2021 were enrolled in this study. Using a simple random grouping method, the patients were randomly assigned to a control group and an observation group in a 1:1 ratio, with 40 patients in each group. The control group received conventional vaseline gauze treatment, while the observation group was treated with a combination of R-bFGF gel and silver ion dressing. After 2 weeks of treatment, the repair effects of both groups were evaluated. Before and after treatment, the Connor-Davidson Resilience Scale (CD-RISC) scores and Visual Analog Scale (VAS) scores were compared between the control and observation groups. Additionally, wound healing time, granulation tissue growth time, wound epithelium formation time, and dressing change times as well as total active motion of the fingers were evaluated and compared between the two groups.Results:The repair effect in the observation group was significantly superior to that in the control group ( Z = 4.92, P < 0.05). Furthermore, the recovery of hand function in the observation group was notably better than that in the control group ( Z = 4.31, P < 0.05). The CD-RISC score in the observation group was significantly higher than that in the control group [(77.54 ± 11.35) points vs. (70.61 ± 9.72) points, t = 2.93, P < 0.05]. Additionally, the VAS score, wound healing time, granulation tissue growth time, wound epithelium formation time, and dressing change times in the observation group were significantly lower or fewer than those in the control group [(4.95 ± 1.13) points vs. (5.52 ± 1.24) points, (10.43 ± 1.65) days vs. (15.54 ± 1.71) days, (7.42 ± 2.35) days vs. (11.56 ± 2.71) days, (10.25 ± 2.47) days vs. (12.82 ± 2.64) days, and (2.12 ± 0.63) times vs. (3.35 ± 0.86) times, t = -2.15, -13.60, -7.30, -4.50, -7.30, all P < 0.05]. Conclusion:The combined use of R-bFGF gel and silver ion dressing effectively enhances the repair outcomes of skin donor sites, thereby improving the psychological well-being and reducing pain perception in patients with hand trauma. This therapeutic approach markedly promotes the prognosis and functional recovery of these patients, offering valuable clinical reference for the treatment of hand injuries.

New concept and strategy of wound treatment in modern wars / 中华创伤杂志

The treatment of war wounds is the core content of military medicine. Considering the development of weapons, the change of war mode and the need of health services, the treatment of war wounds must be adapted to the requirements of the new situation. Wounds in modern wars are the traumas caused in all-domain hybrid warfare. Through local wars and related military operations, foreign armed forces especially the US armed forces have implemented or improved many technologies and health service countermeasures for the treatment of war wounds, and put forward new concepts and strategies for war wound treatment, which may serve as a valuable reference in the establishment of Chinese combat casualty care system in the conditions of future warfare and a combat casualty care system that fits the Chinese characteristics. For this purpose, the author introduced the new concept and strategy of wound treatment in modern wars from two aspects of the overall health and self-rescue and mutual rescue training, extension of the rescue force and application of new technologies in combat casualty care, hoping to provide a reference for the establishment of a combat casualty care system with Chinese characteristics in the conditions of future warfare.

Clinical application of three-dimensional CT angiography in repair of limb wounds with free lateral thoracic perforator flaps / 中华创伤骨科杂志

Objective:To explore the clinical application of three-dimensional CT angiography (3D-CTA) in repair of limb wounds with free lateral thoracic perforator flaps.Methods:A retrospective study was conducted to analyze the clinical data of 61 patients with limb soft tissue defects who had been treated at The Third Department of Orthopedics, Xingtai General Hospital of North China Medical and Health Group from January 2018 to September 2022. There were 37 males and 24 females with an age of (43.9±12.0) years. Thirty-three left and 28 right sides were injured. Soft tissue defects ranged from 4.0 cm × 3.0 cm to 17.0 cm × 8.0 cm, and flap areas from 5.0 cm × 4.0 cm to 18.0 cm × 9.0 cm. The patients were divided into 2 groups according to the different preoperative vascular exploration methods: an ultrasound group of 30 cases subjected to ultrasound Doppler examination and a 3D-CTA group of 31 cases subjected to 3D-CTA examination. The preoperative findings were compared with those of intraoperative exploration in the 2 groups. The operation time, flap survival rate, patient satisfaction with trauma repair, sensory recovery of the flap area, and the excellent and good rate of the donor area were also compared between the 2 groups.Results:The differences in preoperative general data between the 2 groups were not statistically significant, indicating the 2 groups were comparable ( P>0.05). In the ultrasound group, the inraoperative classification of the lateral thoracic perforator flaps showed a low concordance with preoperative classification (Kappa coefficient of 0.104, P=0.088). In the 3D-CTA group, the classification of lateral thoracic perforator flaps was consistent with the preoperative 3D-CTA examination (Kappa coefficient of 1.00, P<0.001). The preoperative measurements in the 3D-CTA group found that the diameter at the origin of the lateral thoracic artery was (1.2±0.3) mm, the vascular pedicle length (8.1±2.1) cm, and the diameter at the perforator exit (0.6±0.2) mm; the preoperative surface positioning at the perforator exit found that the perforator exit was (1.6±0.3) cm above the horizontal line of the subscapular angle and (5.3±1.4) cm outside the vertical line of the subscapular angle. These measurements were similar to the intraoperative ones [(1.1±0.3) mm, (8.3±2.4) cm, (0.7±0.2) mm, (1.5±0.4) cm, and (5.2±1.5) cm], showing no significant differences ( P>0.05). In contrast, the preoperative measurements of the above indexes in the ultrasound group did not coincide with the actual intraoperative measurements, and the differences were all statistically significant ( P<0.05). The operation time, flap survival rate, rate of patient satisfaction with wound repair, rate of sensory recovery in the flap area, and the excellence and good rate of the donor area in the 3D-CTA group were (52.9±16.7) min, 100.0% (31/31), 96.8% (30/31), 83.9% (26/31), and 87.1% (27/31), respectively, which were significantly better than those in the ultrasound group [(76.3±21.4) min, 86.7% (26/30), 76.7% (23/30), 60.0% (18/30), 63.3% (20/30)] ( P<0.05). Conclusions:As preoperative 3D-CTA examination can clarify the types and anatomical characteristics of the lateral thoracic artery and its perforators, it helps the design and harvest of the lateral thoracic perforator flaps. Compared with the ultrasound Doppler examination, preoperative 3D-CTA examination shortens operation time, raises survival rate of the flaps, and facilitates recovery of the appearance and function of the limb wounds, and leads to little impact on the donor site.
