Efectividad del uso transoperatorio de solución electrolizada de superoxidación para la prevención de infecciones postoperatorias en cirugía de terceros molares / Effectiveness of the trans-operative use of electrolyzed superoxidation solution for the prevention of post-operative infections in third molar surgery

La cirugía de terceros molares es uno de los procedimientos más realizados dentro de la práctica odontológica, generalmente conlleva la prescripción de fármacos, incluidos antibióticos indicados para prevenir la aparición de procesos infecciosos. La resistencia antimicrobiana es considerada como un problema de salud pública a nivel mundial, por lo que el uso de antibióticos debe ser cauteloso. La solución electrolizada de súperoxidación ha demostrado tener efectos bactericidas, virucidas y ha sido utilizada para la prevención y el tratamiento de procesos infecciosos. El objetivo del presente estudio fue demostrar la efectividad de dicha solución en la prevención de infecciones posteriores a la cirugía de terceros molares. Se realizó un estudio aleatorizado, ciego, prospectivo en 20 pacientes utilizando un diseño split mouth, en donde cada paciente fue sujeto control y experimental, en el grupo control se irrigó durante el procedimiento con solución de súperoxidación y no se prescribió antibiótico posterior, mientras que en el grupo control se irrigó con solución fisiológica y se prescribió antibiótico posterior. Se realizaron 40 cirugías en 20 pacientes utilizando en cada paciente ambas terapéuticas. Se analizó el dolor postoperatorio, inflamación y presencia de infección. El dolor y la inflamación fueron ligeramente superiores en el grupo experimental al tercer día; sin embargo, al séptimo día los resultados fueron similares. No se presentó ningún caso de infección postoperatoria. El uso de solución de súperoxidación transoperatoria puede ser una herramienta muy útil en la prevención de infecciones postoperatorias posterior a cirugía de terceros molares en pacientes sanos en cirugías con dificultad leve a moderada (AU)

Third molar surgery is one of the most performed procedures in dental practice, generally involving the prescription of drugs including antibiotics indicated to prevent the onset of infectious processes. Antimicrobial resistance is considered a public health problem worldwide, so the use of antibiotics should be cautious. The electrolyzed super oxidation solution has been shown to have bactericidal and virucidal effects and has been used for the prevention and treatment of infectious processes. The objective of the present study was to demonstrate the effectiveness of said solution in the prevention of infections after third molar surgery. A randomized, blind, prospective study was conducted in 20 patients using a split mouth design where each patient was a control and experimental subject, in the control group they were irrigated during the procedure with super oxidation solution and no subsequent antibiotic was prescribed. while the control group was irrigated with physiological solution and a subsequent antibiotic was prescribed. Forty surgeries were performed on 20 patients using both therapies in each patient. Postoperative pain, inflammation and presence of infection were analyzed. Pain and inflammation were slightly higher in the experimental group on third day, however on seventh day the results were similar. There were no cases of postoperative infection. The use of trans operative super oxidation solution can be a very useful tool in the prevention of postoperative infections after third molar surgery in healthy patients undergoing surgeries with mild to moderate difficulty.(AU)

Association between enhanced recovery after surgery protocol compliance and clinical complications: a cohort study

Abstract Background Enhanced Recovery After Surgery (ERAS) protocol is composed by evidence-based interventions that aim to improve recovery through a reduction in surgical stress response. Although ERAS protocols have been introduced across the globe, exhaustive implementation is not as common. We aimed to study the ERAS protocol compliance in colorectal surgery, assessing the relationship between compliance and postoperative complications. Methods A single-center cohort study was conducted. All consecutive patients admitted to elective colorectal surgery were included. We assessed study endpoints according to ERAS protocol perioperative compliance score above 75%. Our primary endpoint was a composite of postoperative events, which includes in-hospital postoperative complications and need for reoperation after 30 days and need for readmission after discharge. Secondary endpoints were surgery-to-discharge time, postoperative use of only non-opioid adjuvants and the individual components of the primary endpoint. Results A total of 224 colorectal patients were included. The primary endpoint occurred in 59.2% (n = 58) of non-compliant patients comparing to 34.1% (n = 43) in compliant patients. In univariate analysis, compliance to ERAS protocol had an inferior risk for the primary endpoint (p< 0.001). In a logistic regression model, compliance was independently associated with a reduced risk for the primary endpoint with a odds-ratio of 0.42 (95% CI 0.23-0.75, p= 0.004). Conclusion Compliance with the ERAS protocol is associated with less complications, a reduced surgery-to-discharge time and use of only non-opioid adjuvants in the postoperative period. More studies are needed to target the most appropriate compliance goal.

Implementation of an ERAS program in patients undergoing thoracic surgery at a third-level university hospital: an ambispective cohort study

Abstract Objective To analyze the effects of an ERAS program on complication rates, readmission, and length of stay in patients undergoing pulmonary resection in a tertiary university hospital. Methods Ambispective cohort study with a prospective arm of 50 patients undergoing thoracic surgery within an ERAS program (ERAS group) versus a retrospective arm of 50 patients undergoing surgery before the protocol was implemented (Standard group). The primary outcome was the number of patients with 30-day surgical complications. Secondary outcomes included ERAS adherence, non-surgical complications, mortality, readmission, reintervention rate, pain, and hospital length of stay. We performed a multivariate logistic analysis to study the correlation between outcomes and ERAS adherence. Results In the univariate analysis, we found no difference between the two groups in terms of surgical complications (Standard 18 [36%] vs. ERAS 12 [24%], p = 0.19). In the ERAS group, only the readmission rate was significantly lower (Standard 15 [30%] vs. ERAS 6 [12%], p = 0.03). In the multivariate analysis, ERAS adherence was the only factor associated with a reduction in surgical complications (OR [95% CI] = 0.02 [0.00, 0.59], p = 0.03) and length of stay (HR [95% CI] = 18.5 [4.39, 78.4], p < 0.001). Conclusions The ERAS program significantly reduced the readmission rate at our hospital. Adherence to the ERAS protocol reduced surgical complications and length of stay.

Preliminary application of combined auditory monitoring technique in resection of vestibular neurinoma / 中华耳鼻咽喉头颈外科杂志

Objective: To explore the value of electrically evoked auditory brainstem response (EABR) monitoring combined with brainstem auditory evoked potential (BAEP) and compound action potential (CAP) monitoring during vestibular schwannoma resection for the protection of the cochlear nerve. Methods: Clinical data from 12 patients with vestibular schwannomas who had useful hearing prior to surgery were analyzed at the PLA General Hospital from January to December 2021. Among them, there were 7 males and 5 females, ranging in age from 25 to 59 years. Before surgery, patients underwent audiology assessments (including pure tone audiometry, speech recognition rate, etc.), facial nerve function evaluation, and cranial MRI. They then underwent vestibular schwannoma resection via the retrosigmoid approach. EABR, BAEP, and CAP were simultaneously monitored during surgery, and patients' hearing preservation was observed and analyzed after surgery. Results: Prior to surgery, the average PTA threshold of the 12 patients ranged from11 to 49 dBHL, with a SDS of 80% to 100%. Six patients had grade A hearing, and six patients had grade B hearing. All 12 patients had House-Brackman grade I facial nerve function prior to surgery. The MRI indicated tumor diameters between 1.1 and 2.4 cm. Complete removal was achieved in 10/12 patients, while near-total removal was achieved in 2/12 patients. There were no serious complications at the one-month follow-up after surgery. At the three-month follow-up, all 12 patients had House-Brackman grade I or II facial nerve function. Under EABR with CAP and BAEP monitoring, successful preservation of the cochlear nerve was achieved in six of ten patients (2 with grade B hearing, 3 with grade C hearing, and 1 with grade D hearing). Successful preservation of the cochlear nerve was not achieved in another four patients (all with grade D hearing). In two patients, EABR monitoring was unsuccessful due to interference signals; however, Grade C or higher hearing was successfully preserved under BAEP and CAP monitoring. Conclusion: The application of EABR monitoring combined with BAEP and CAP monitoring during vestibular schwannoma resection can help improve postoperative preservation of the cochlear nerve and hearing.

Prevention and treatment of postoperative complications of esophageal cancer / 中华胃肠外科杂志

Surgery is the primary treatment for esophageal cancer, but the postoperative complication rate remains high. Therefore, it is important to prevent and manage postoperative complications to improve prognosis. Common perioperative complications of esophageal cancer include anastomotic leakage, gastrointestinal tracheal fistula, chylothorax, and recurrent laryngeal nerve injury. Respiratory and circulatory system complications, such as pulmonary infection, are also quite common. These surgery-related complications are independent risk factors for cardiopulmonary complications. Complications, such as long-term anastomotic stenosis, gastroesophageal reflux, and malnutrition are also common after esophageal cancer surgery. By effectively reducing postoperative complications, the morbidity and mortality of patients can be reduced, and their quality of life can be improved.

Advances of perioperative acute kidney injury in elderly patients undergoing non-cardiac surgery / 中南大学学报(医学版)

The risk of developing perioperative acute kidney injury (AKI) in elderly patients increases with age. The combined involvement of aging kidneys, coexisting multiple underlying chronic diseases, and increased exposure to potential renal stressors and nephrotoxic drugs or invasive procedures constitute susceptibility factors for AKI in elderly patients. The perioperative AKI in elderly patients undergoing noncardiac surgery has its own specific population characteristics, so it is necessary to further explore the characteristics of AKI in elderly patients in terms of epidemiology, clinical diagnosis, risk factors, and preventive and curative measures to provide meaningful clinical advice to improve prognosis, accelerate recovery, and reduce medical burden in elderly patients. Since AKI has the fastest-growing incidence in older patients and is associated with a worse prognosis, early detection, early diagnosis, and prevention of AKI are important for elderly patients in the perioperative period. Large, multicenter, randomized controlled clinical studies in elderly non-cardiac surgery patients with AKI can be conducted in the future, with the aim of providing the evidence to reduce of the incidence of AKI and to improve the prognosis of patients.

Clinical study of using basement membrane biological products in pelvic floor reconstruction during pelvic exenteration / 中华胃肠外科杂志

Objective: To investigate the value of reconstruction of pelvic floor with biological products to prevent and treat empty pelvic syndrome after pelvic exenteration (PE) for locally advanced or recurrent rectal cancer. Methods: This was a descriptive study of data of 56 patients with locally advanced or locally recurrent rectal cancer without or with limited extra-pelvic metastases who had undergone PE and pelvic floor reconstruction using basement membrane biologic products to separate the abdominal and pelvic cavities in the Department of Anorectal Surgery of the Second Affiliated Hospital of Naval Military Medical University from November 2021 to May 2022. The extent of surgery was divided into two categories: mainly inside the pelvis (41 patients) and including pelvic wall resection (15 patients). In all procedures, basement membrane biologic products were used to reconstruct the pelvic floor and separate the abdominal and pelvic cavities. The procedures included a transperitoneal approach, in which biologic products were used to cover the retroperitoneal defect and the pelvic entrance from the Treitz ligament to the sacral promontory and sutured to the lateral peritoneum, the peritoneal margin of the retained organs in the anterior pelvis, or the pubic arch and pubic symphysis; and a sacrococcygeal approach in which biologic products were used to reconstruct the defect in the pelvic muscle-sacral plane. Variables assessed included patients' baseline information (including sex, age, history of preoperative radiotherapy, recurrence or primary, and extra-pelvic metastases), surgery-related variables (including extent of organ resection, operative time, intraoperative bleeding, and tissue restoration), post-operative recovery (time to recovery of bowel function and time to recovery from empty pelvic syndrome), complications, and findings on follow-up. Postoperative complications were graded using the Clavien-Dindo classification. Results: The median age of the 41 patients whose surgery was mainly inside the pelvis was 57 (31-82) years. The patients comprised 25 men and 16 women. Of these 41 patients, 23 had locally advanced disease and 18 had locally recurrent disease; 32 had a history of chemotherapy/immunotherapy/targeted therapy and 24 of radiation therapy. Among these patients, the median operative time, median intraoperative bleeding, median time to recovery of bowel function, and median time to resolution of empty pelvic syndrome were 440 (240-1020) minutes, 650 (200-4000) ml, 3 (1-9) days, and 14 (5-105) days, respectively. As for postoperative complications, 37 patients had Clavien-Dindo < grade III and four had ≥ grade III complications. One patient died of multiple organ failure 7 days after surgery, two underwent second surgeries because of massive bleeding from their pelvic floor wounds, and one was successfully resuscitated from respiratory failure. In contrast, the median age of the 15 patients whose procedure included combined pelvic and pelvic wall resection was 61 (43-76) years, they comprised eight men and seven women, four had locally advanced disease and 11 had locally recurrent disease. All had a history of chemotherapy/ immunotherapy and 13 had a history of radiation therapy. The median operative time, median intraoperative bleeding, median time to recovery of bowel function, and median time to relief of empty pelvic syndrome were 600 (360-960) minutes, 1600 (400-4000) ml, 3 (2-7) days, and 68 (7-120) days, respectively, in this subgroup of patients. Twelve of these patients had Clavien-Dindo < grade III and three had ≥ grade III postoperative complications. Follow-up was until 31 October 2022 or death; the median follow-up time was 9 (5-12) months. One patient in this group died 3 months after surgery because of rapid tumor progression. The remaining 54 patients have survived to date and no local recurrences have been detected at the surgical site. Conclusion: The use of basement membrane biologic products for pelvic floor reconstruction and separation of the abdominal and pelvic cavities during PE for locally advanced or recurrent rectal cancer is safe, effective, and feasible. It improves the perioperative safety of PE and warrants more implementation.

Effect of intraoperative alveolar recruitment maneuver on intraoperative oxygenation and postoperative pulmonary function tests in patients undergoing robotic-assisted hysterectomy: a single-blind randomized study

Abstract Background Robotic-Assisted Hysterectomies (RAH) require Trendelenburg positioning and pneumoperitoneum, which further accentuate alteration in respiratory mechanics induced by general anesthesia. The role of Recruitment Maneuver (RM) as a lung-protective strategy during intraoperative surgical settings has not been much studied. We planned this study to evaluate the effect of RM on perioperative oxygenation and postoperative spirometry using PaO2/FiO2 and FEV1/FVC, respectively in patients undergoing RAH. Methods Sixty-six ASA I‒II female patients scheduled for elective RAH were randomized into group R (recruitment maneuver, n = 33) or group C (control, n = 33). Portable spirometry was done one day before surgery. Patients were induced with general anesthesia, and mechanical ventilation started with volume control mode, with Tidal Volume (TV) of 6-8 mL.kg−1, Respiratory Rate (RR) of 12 min, inspiratory-expiratory ratio (I: E ratio) of 1:2, FiO2 of 0.4, and Positive End-Expiratory Pressure (PEEP) of 5 cmH2O. Patients in group R received recruitment maneuvers of 30 cmH2O every 30 minutes following tracheal intubation. The primary objectives were comparison of oxygenation and ventilation between two groups intraoperatively and portable spirometry postoperatively. Postoperative pulmonary complications, like desaturation, pulmonary edema, pneumonia, were monitored. Results Patients who received RM had significantly higher PaO2 (mmHg) (203.2+-24.3 vs. 167.8+-27.3, p < 0.001) at T2 (30 min after the pneumoperitoneum). However, there was no significant difference in portable spirometry between the groups in the postoperative period (FVC, 1.40 ± 0.5 L vs. 1.32 ± 0.46 L, p= 0.55). Conclusion This study concluded that intraoperative recruitment did not prevent deterioration of postoperative spirometry values; however, it led to improved oxygenation intraoperatively.

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.

The clinical impact of the systolic volume variation guided intraoperative fluid administration regimen on surgical outcomes after pancreaticoduodenectomy: a retrospective cohort study

Abstract Background Pancreaticoduodenectomy is associated with high morbidity. Many preoperative variables are risk factors for postoperative complications, but they are primarily non-modifiable. It is not clear whether an intraoperative goal-directed fluid regimen might be associated with fewer postoperative surgical complications compared to current conservative, non-goal-directed fluid practices. We hypothesize that the use of Systolic Volume Variation (SVV)-guided intraoperative fluid administration might be beneficial. Methods Data from 223 patients who underwent pancreaticoduodenectomy in our institution between 2015 and 2019 were reviewed. Patients were classified into two groups based on the use of intraoperative use of SVV to guide the administration of fluids. The decision to use SVV or not was made by the attending anesthesiologist. Subjects were classified into SVV-guided intraoperative fluid therapy (SVV group) and non-SVV-guided intraoperative fluid therapy (non-SVV group). Uni and multivariate regression analyses were conducted to determine if SVV-guided fluid therapy was significantly associated with a lower incidence of postoperative surgical complications, such as Postoperative Pancreatic Fistula (POPF), Delayed Gastric Emptying (DGE), among others, after adjusting for confounders. Results Baseline, demographic, and intraoperative characteristics were similar between SVV and non-SVV groups. In the multivariate analysis, the use of SVV guidance was significantly associated with fewer postoperative surgical complications (OR = 0.48; 95% CI 0.25-0.91; p= 0.025), even after adjusting for significant covariates, such as perioperative use of epidural, pancreatic gland parenchyma texture, and diameter of the pancreatic duct. Conclusions VV-guided intraoperative fluid administration might be associated with fewer postoperative surgical complications after pancreaticoduodenectomy.

Adding autogenic drainage to chest physiotherapy after upper abdominal surgery: effect on blood gases and pulmonary complications prevention. Randomized controlled trial

ABSTRACT BACKGROUND: Hypoxemia and pulmonary complications are common after upper abdominal surgery (UAS). OBJECTIVE: To examine whether inclusion of autogenic drainage (AD) in chest physiotherapy after UAS confers additional benefits in improving blood gases and reducing postoperative pulmonary complications (PPCs). DESIGN AND SETTING: Randomized controlled study conducted at Kasr Al-Ainy teaching hospital, Egypt. METHODS: A randomized controlled trial was conducted on 48 subjects undergoing elective UAS with high risk of developing PPCs. The study group received AD plus routine chest physiotherapy (deep diaphragmatic breathing, localized breathing and splinted coughing) and the control group received routine chest physiotherapy only. The outcomes included arterial blood gases measured at the first and seventh postoperative days, incidence of PPCs within the first seven days and length of hospital stay. RESULTS: Baseline characteristics were similar between groups. In the AD group, SaO2, PaO2, PaCO2 and HCO3 significantly improved (P < 0.05) while in the physiotherapy group, only SaO2 and PaO2 significantly improved (P < 0.05). Nonetheless, significant differences in post-treatment SaO2 and PaO2 between the groups were observed. The overall incidence of PPCs was 16.66% (12.5% in the AD group and 20.8% in the physiotherapy group) (absolute risk reduction -8.3%; 95% confidence interval, CI, -13.5 to 29.6%), with no significant difference between the groups. The AD group had a significantly shorter hospital stay (P = 0.0001). CONCLUSION: Adding AD to routine chest physiotherapy after UAS provided a favorable blood gas outcome and reduced the length of hospital stay. It tended to reduce the incidence of PPCs. TRIAL REGISTRATION: ClinicalTrials.gov: NCT04446520.

Cuidados de enfermería al paciente trasplantado renal período pre-operatorio, pos trasplante inmediato y temprano en la Unidad de Trasplante Renal del Hospital de Especialidades Carlos Andrade Marín / Nursing care of the renal transplant patient pre-operative, immediate posttransplant and early post-transplant periods in the Renal Transplant Unit of the Carlos Andrade Marín Specialties Hospital

El trasplante renal es considerado como la mejor alternativa de tratamiento sustitutivo para la enfermedad renal crónica terminal (ERCT)1, es el procedimiento quirúrgico que consiste en reemplazar un riñón sano de un donante vivo o cadavérico a una persona con diagnóstico de ERCT, que ayuda a mejorar su calidad de vida, la reinserción a sus actividades sociales, físicas, emocionales, laborales y sexuales. La Organización Nacional de Trasplantes de España (ONT) en el año 2018, reportó que en la Unión Europea se realizaron 21 102 y en Latinoamérica 12 806 trasplantes renales2, en Ecuador el Ministerio de Salud Pública (MSP) en los años 2007-2020 reportó un total de 1 6153, le correspondió al Hospital de Especialidades Carlos Andrade Marín (HECAM) el 32% del total de trasplantes renales realizados entre el periodo 2007-20184. La evaluación del potencial receptor es realizada por un equipo multidisciplinario con formación académica, experiencia certificada en los diferentes procesos y acreditados por el Instituto Nacional de Donación y Trasplantes (INDOT)5. Los cuidados de enfermería enmarcados en esta ruta, son especializados e integrales, que incluyen los períodos pre operatorio, pos trasplante inmediato y temprano al incorporar además un proceso educativo entre enfermera, paciente y familia/ cuidador, con el fin de preservar la sobrevida del injerto.

Renal transplantation is considered the best alternative replacement treatment for end-stage chronic kidney disease (ESRD)1, it is the surgical procedure that consists of replacing a healthy kidney from a living or cadaveric donor to a person diagnosed with ESRD, which helps to improve their quality of life, reintegration to their social, physical, emotional, work and sexual activities. The National Transplant Organization of Spain (ONT) in 2018, reported that In the European Union 21 102 and in Latin America 12 806 renal transplants were performed2, in Ecuador the Ministry of Public Health (MSP) in the years 2007-2020 reported a total of 1 6153, corresponded to the Carlos Andrade Marín Specialties Hospital (HECAM) 32% of the total number of renal transplants performed between 2007-20184. The evaluation of the potential recipient is performed by a multidisciplinary team with academic training, certified experience in the different processes and accredited by the National Institute of Donation and Transplantation (INDOT)5. The nursing care framed in this route is specialized and comprehensive, including the pre-operative, immediate post-transplant and early post-transplant periods, incorporating an educational process between nurse, patient and family/caregiver, in order to preserve graft survival.

Evolución del traumatismo penetrante cardíaco operado / Penetrating cardiac injury: evolution of characteristics, severity and mortality in surgery treated patients

Resumen Introducción: El traumatismo penetrante cardíaco (TPC) es una lesión poco frecuente y con alta morbilidad y mortalidad. Objetivo: Analizar la evolución de características clínicas, anatómicas, gravedad, morbilidad y mortalidad de pacientes operados por TPC. Materiales y Métodos: Estudio analítico de pacientes tratados quirúrgicamente por TPC en Hospital Clínico Regional "Dr. Guillermo Grant Benavente", Concepción, Chile. Se analizaron los periodos: enero-1990 a diciembre-2004 y enero-2005 a diciembre-2019. Se comparó: sexo, edad, lesiones asociadas, agente y mecanismo del traumatismo, comportamiento fisiopatológico, ubicación anatómica de la lesión, clasificaciones del traumatismo cardíaco Attar, Saadia y OIS-AAST, IGT (índices de gravedad del traumatismo): ISS, RTS-T y TRISS, morbilidad y mortalidad según periodos. Se realizó análisis estadístico con SPSS25®, se utilizaron las pruebas chi-cuadrado, exacta de Fisher y Mann-Whitney. Se consideró significativo un valor p < 0,05. Resultados: Total 235 TPC, 112 en el primer periodo y 123 en el segundo. Mecanismo arma blanca en 96 (85,7%) y 104 (84,6%) según periodos. En el segundo periodo se observó un aumento de lesiones extratorácicas asociadas, paro cardiorrespiratorio y lesión de ubicación izquierda. Las clasificaciones del traumatismo cardíaco y los IGT ISS, RTS-T y TRISS mostraron mayor gravedad y probabilidad de muerte en los pacientes del segundo periodo. La mortalidad no mostró diferencias: 14 (12,5%) y 14 (11,4%) según periodos (p = 0,792). Discusión: En nuestra serie los pacientes tratados por TPC han evolucionado hacia un perfil de mayor gravedad tanto en parámetros fisiológicos como anatómicos. La mortalidad se ha mantenido estable a través del tiempo.

Background: Penetrating cardiac injury (PCI) is a rare injury with high morbidity and mortality. Aim: To analyze the evolution of clinical and anatomical characteristics, severity, morbidity and mortality of patients operated on by PCI. Materials and Methods: Analytical study of patients surgically treated for PCI at the "Guillermo Grant Benavente" Regional Clinical Hospital, Concepción, Chile. Two periods were analyzed: January-1990 to December-2004 and January-2005 to December-2019. Sex, age, associated injuries, trauma agent and mechanism, pathophysiological behavior, anatomic location of the injury, classifications of cardiac trauma: Attar, Saadia and OIS-AAST, TSI (trauma severity indices): ISS, RTS-T and TRISS, morbidity and mortality were compared according to periods. Statistical analysis was performed with SPSS25®, the chi-square, Fisher exact and Mann-Whitney tests were used. A p value < 0.05 was considered significant. Results: Total 235 PCI, 112 in the first period and 123 in the second. Stab as mechanism in 96 (85.7%) and 104 (84.6%) according to periods. An increase in associated extra thoracic injuries, cardiorespiratory arrest, and injury to the left location were observed in the second period. The cardiac trauma classifications and the TSI ISS, RTS-T and TRISS showed greater severity and probability of death in the second period patients. Mortality did not show differences: 14 (12.5%) and 14 (11.4%) according to periods, p = 0.792. Discussion: In our series, patients treated with PCI have evolved towards a more severity profile in both, physiological and anatomical parameters. Mortality has been stable over time.
