ABSTRACT

Abstract Spinal cord infarction is an uncommon phenomenon, which can be caused by different etiologies, constituting a real diagnostic challenge which can lead to devastating consequences. General anesthesia in beach chair positioning with intraoperative hypotension in order to avoid surgical bleeding are associated with hypoperfusion and potential neurological ischemia-related complications. We present a case of spinal cord ischemia in the context of shoulder surgery in a beach chair position.

ABSTRACT

Abstract Background: The Argon Beam Coagulator (ABC) achieves hemostasis but has potential complications in the form of argon gas embolisms. Risk factors for embolisms have been identified and ABC manufacturers have developed guidelines for usage of the device to prevent embolism development. Case report: A 49 year-old male with history of recurrent cholangiocarcinoma status post resection presented for resection of a cutaneous biliary fistula. Shortly after initial use of the ABC, the patient underwent cardiac arrest. After resuscitation, air bubbles were observed in the left ventricle via Transesophageal Echo (TEE). Conclusion: Although argon embolisms have been described more commonly during laparoscopies, this patient most likely experienced an argon gas embolism during an open resection of a cutaneous biliary fistula via the biliary tract or vein with possible transpulmonary passage of the embolism. Consequently, a high degree of suspicion should be maintained for an argon gas embolism during ABC use in laparoscopic, open, and cutaneous surgeries.


Resumo Introdução: A Coagulação por Feixe de Argônio (CFA) promove hemostasia, mas pode levar a complicações na forma de embolia por gás argônio. Os fatores de risco para embolias foram identificados e os fabricantes de aparelhos de CFA desenvolveram diretrizes para o uso do dispositivo para impedir a ocorrência de embolia. Relato de caso: Paciente masculino de 49 anos com história de colangiocarcinoma recorrente pós-ressecção foi submetido à ressecção de fístula cutâneo-biliar. Logo após o início do uso do aparelho de CFA, o paciente apresentou parada cardíaca. Após o retorno da atividade cardíaca, a Eecocardiografia Transesofágica (ETE) detectou bolhas de ar no ventrículo esquerdo. Conclusões: Embora a embolia associada ao argônio seja mais frequentemente descrita durante laparoscopia, este paciente mais provavelmente apresentou embolia provocada pelo argônio durante cirurgia aberta para ressecção de fístula cutâneo-biliar, após o argônio ganhar acesso à circulação sanguínea através das vias biliares ou da veia biliar e possível passagem do êmbolo pela circulação pulmonar. Desta maneira, deve-se suspeitar de embolia por argônio, de forma judiciosa, durante o uso de CFA em procedimento cirúrgico laparoscópico, aberto ou cutâneo.

ABSTRACT

Abstract Introduction Tranexamic acid is a hemostatic agent, which inhibits fibrin degradation, which may be beneficial in controlling bleeding during surgery. Objectives The purpose of this study was to provide a meta-analysis and review of the effects of tranexamic acid on hemorrhage and surgical fields and side effects on patients during endoscopic sinus surgery. Methods Two authors independently searched six databases (Medline, Scopus, Embase, Web of Science, Google Scholar and Cochrane library) from the start of article collection until July 2018. Postoperative complications such as intraoperative bleeding, operative time, hypotension, nausea, vomiting, and coagulation profile were included in the analysis of tranexamic acid (Treatment Group) and placebo (Control Group) during the operation. Results The amount of blood loss during surgery was statistically lower in the treatment group compared to the placebo group, and the surgical field quality was statistically higher in the treatment group than in the placebo group. On the other hand, there was no significant difference in operation time, hemodynamics, or coagulation profile between groups. In addition, tranexamic acid had no significant effect on vomiting and thrombosis compared to the Control Group. Conclusion This meta-analysis has shown that topical administration of tranexamic acid can reduce the amount of bleeding during surgery and improve the overall quality of the surgery. Hemodynamic instability during surgery, vomiting after surgery, or abnormal clotting profile were not reported. Additional studies are needed to confirm the results of this study because there are fewer studies.


Resumo Introdução O ácido tranexâmico é um agente hemostático, que inibe a degradação da fibrina e pode ser benéfico no controle do sangramento durante a cirurgia. Objetivos Fazer uma metanálise e revisão dos efeitos do ácido tranexâmico na hemorragia e nos campos cirúrgicos e efeitos colaterais em pacientes durante a cirurgia endoscópica do seio nasal. Método Dois autores realizaram independentemente uma busca em seis bancos de dados (Medline, Scopus, Embase, Web of Science, Google Scholar e Cochrane) desde o início da coleta de artigos até julho de 2018. Complicações pós-operatórias como sangramento intraoperatório, tempo operatório, hipotensão, náusea, vômitos e perfil de coagulação foram incluídos na análise do ácido tranexâmico (grupo de tratamento) e placebo (grupo controle) durante a cirurgia. Resultados A quantidade de perda de sangue durante a cirurgia foi estatisticamente menor no grupo de tratamento comparado com o grupo placebo e a qualidade do campo cirúrgico foi estatisticamente maior no grupo de tratamento do que no grupo placebo. Por outro lado, não houve diferença significante no tempo cirúrgico, hemodinâmica ou perfil de coagulação entre os grupos. Além disso, o ácido tranexâmico não teve efeito significante na ocorrência de vômitos e trombose em comparação ao grupo controle. Conclusão Esta metanálise mostrou que a administração tópica de ácido tranexâmico pode reduzir a quantidade de sangramento durante a cirurgia e melhorar a qualidade geral dela. Instabilidade hemodinâmica durante a cirurgia, vômitos após a cirurgia ou perfil de coagulação anormal não foram relatados. Estudos adicionais são necessários para confirmar os resultados desta pesquisa, porque há poucos estudos na literatura.

ABSTRACT

ABSTRACT Purpose: To investigate risk factors for complications in patients undergoing adrenalectomy. Materials and Methods: A retrospective search of our institutional database was performed of patients who underwent adrenalectomy, between 2014 and 2018. Clinical parameters and adrenal disorder characteristics were assessed and correlated to intra and post-operative course. Complications were analyzed within 30-days after surgery. A logistic regression was performed in order to identify independent predictors of morbidity in patients after adrenalectomy. Results: The files of 154 patients were reviewed. Median age and Body Mass Index (BMI) were 52-years and 27.8kg/m2, respectively. Mean tumor size was 4.9±4cm. Median surgery duration and estimated blood loss were 140min and 50mL, respectively. There were six conversions to open surgery. Minor and major post-operative complications occurred in 17.5% and 8.4% of the patients. Intra-operative complications occurred in 26.6% of the patients. Four patients died. Mean hospitalization duration was 4-days (Interquartile Range: 3-8). Patients age (p=0.004), comorbidities (p=0.003) and pathological diagnosis (p=0.003) were independent predictors of post-operative complications. Tumor size (p<0.001) and BMI (p=0.009) were independent predictors of intra-operative complications. Pathological diagnosis (p<0.001) and Charlson score (p=0.013) were independent predictors of death. Conclusion: Diligent care is needed with older patients, with multiple comorbidities and harboring unfavorable adrenal disorders (adrenocortical carcinoma and pheocromocytoma), who have greater risk of post-operative complications. Patients with elevated BMI and larger tumors have higher risk of intra, but not of post-operative complications.

ABSTRACT

ABSTRACT Introduction: To determine the impact of time from biopsy to surgery on outcomes following radical prostatectomy (RP) as the optimal interval between prostate biopsy and RP is unknown. Material and methods: We identified 7, 350 men who underwent RP at our institution between 1994 and 2012 and had a prostate biopsy within one year of surgery. Patients were grouped into five time intervals for analysis: ≤ 3 weeks, 4-6 weeks, 7-12 weeks, 12-26 weeks, and > 26 weeks. Oncologic outcomes were stratified by NCCN disease risk for comparison. The associations of time interval with clinicopathologic features and survival were evaluated using multivariate logistic and Cox regression analyses. Results: Median time from biopsy to surgery was 61 days (IQR 37, 84). Median follow-up after RP was 7.1 years (IQR 4.2, 11.7) while the overall perioperative complication rate was 19.7% (1,448/7,350). Adjusting for pre-operative variables, men waiting 12-26 weeks until RP had the highest likelihood of nerve sparing (OR: 1.45, p = 0.02) while those in the 4-6 week group had higher overall complications (OR: 1.33, p = 0.01). High risk men waiting more than 6 months had higher rates of biochemical recurrence (HR: 3.38, p = 0.05). Limitations include the retrospective design. Conclusions: Surgery in the 4-6 week time period after biopsy is associated with higher complications. There appears to be increased biochemical recurrence rates in delaying RP after biopsy, for men with both low and high risk disease.

ABSTRACT

Background: Placing central venous lines under ultrasonographic guidance reduces the complications of the procedure. Aim: To compare prevalences of complications of central venous line placements with or without ultrasonographic guidance. Material and Methods: Descriptive study that contemplated the comparison of two groups of patients subjected to a central venous line placement at a nephrology service for renal replacement therapy. In one group of 100 patients, the line was placed without ultrasonographic guidance between 2008 and 2012. Between 2015 and 2017 the line was placed in 138 patients using ultrasonographic guidance. The prevalences of complications with both types of procedures were recorded. Results: The frequency of complications of procedures with and without ultrasonographic guidance was 0.7 and 18% respectively (prevalence ratio 0.04, 95% confidence interval 0-0.3). Ninety five percent of recorded complications were arterial puncture, followed by hematomas in 10% and pneumothorax in 5%. The higher prevalence of complications was observed in emergency line placement without ultrasonographic guidance. There was a direct association between the number of line placement attempts in a single procedure and the prevalence of complications. Conclusions: Ultrasonographic guidance is associated with a reduction in the prevalence of central venous line complications.

ABSTRACT

Abstract Background: The analysis of risk factors for predicting related complications has not been reported to date. Objective: This study aims to investigate the risk factors of related complications of percutaneous transluminal septal myocardial ablation (PTSMA) for hypertrophic obstructive cardiomyopathy (HOCM) retrospectively. Method: Clinical data, and one-year follow-up results of patients with HOCM, who underwent PTSMA between January 2000 and July 2013 in the Department of Cardiology, Liaoning Province People's Hospital, Liaoning Province, China, were retrospectively analyzed to determine risk factors for operative complications with multiple logistic regression analysis. All p values are two-sided, with values of p < 0.05 being considered statistically significant. Results: Among 319 patients with HOCM, PTSMA was performed in 224 patients (120 males and 104 females, mean age was 48.20 ± 14.34 years old). The incidence of PTSMA procedure-related complications was 36.23% (66/224), which included three cardiac deaths, two cardiac shocks, one ST-segment elevated myocardial infarction, two ventricular fibrillations, 20 third-degree atrioventricular (AV) blocks (four patients were implanted with a permanent pacemaker (PPM)), 32 complete right bundle branch blocks, two complete left bundle branch blocks, and four puncture-related complications. After multivariate logistic regression analysis, it was found that age, gender, coronary artery diseases, diabetes, heart rate, cardiac function on admission, the number of septal ablations, and the volume of alcohol were not independent risk factors correlated to the whole complications, except for hypertension (OR: 4.856; 95% CI: 1.732-13.609). Early experience appears to be associated with the occurrence of complications. Conclusion: Hypertension was an independent risk factor for PTSMA procedure-related complications. It might be much safer and more efficient if PTSMA procedures are restricted to experienced centers, according to the analysis results for the learning curve.


Resumo Fundamento: A análise dos fatores de risco para previsão de complicações relacionadas não foi relatada até o momento. Objetivo: Este estudo tem como objetivo investigar retrospectivamente os fatores de risco de complicações relacionadas da ablação miocárdica septal transluminal percutânea (PTSMA) para cardiomiopatia hipertrófica obstrutiva (CMHO). Método: Dados clínicos e resultados de acompanhamento de um ano de pacientes com CMHO submetidos a PTSMA entre janeiro de 2000 e julho de 2013 no Departamento de Cardiologia do Hospital Popular da Província de Liaoning, província de Liaoning, China, foram analisados retrospectivamente para determinar fatores de risco para complicações operatórias com análise de regressão logística múltipla. Todos os valores de p são bilaterais, com valores de p < 0,05 sendo considerados estatisticamente significativos. Resultados: Entre os 319 pacientes com CMHO, a PTSMA foi realizada em 224 pacientes (120 homens e 104 mulheres, com idade média de 48,20 ± 14,34 anos). A incidência de complicações relacionadas ao procedimento PTSMA foi de 36,23% (66/224), incluindo três mortes cardíacas, dois choques cardíacos, um infarto do miocárdio com supradesnivelamento de ST, duas fibrilações ventriculares e 20 bloqueios atrioventriculares (AV) de terceiro grau (quatro pacientes receberam implantes de marca-passo permanente), 32 bloqueios completos de ramo direito, dois bloqueios completos de ramo esquerdo e quatro complicações relacionadas com a punção. Após análise de regressão logística multivariada, verificou-se que idade, sexo, doenças coronarianas, diabetes, frequência cardíaca, função cardíaca à admissão, número de ablações septais e volume de álcool não foram fatores de risco independentes correlacionados com as complicações totais, exceto para hipertensão (OR: 4,856; IC 95%: 1,732-13,609). A experiência principiante parece estar associada à ocorrência de complicações. Conclusão: A hipertensão arterial foi um fator de risco independente para complicações relacionadas com o procedimento de PTSMA. Pode ser muito mais seguro e eficiente se os procedimentos de PTSMA forem restritos a centros experientes, de acordo com os resultados da análise para a curva de aprendizado.

ABSTRACT

Background: Perioperative cardiac arrest (PCA) is a rare but important event in the operating room. Aim: To describe PCA events at a Clinical Hospital in Santiago, Chile. Material and Methods: Registry of PCA that occurred in the operating room (OR) and during procedures not carried out in the OR between September 2006 and November 2017. Precipitating events, type of anesthesia and results of resuscitation maneuvers were described. Results: Eighty events (five outside of the OR) during 170,431 surgical procedures were recorded, resulting in an incidence of 4.4 events per 10,000 interventions. Hypotension/hypoperfusion was the most frequently found preexisting condition (42.5%). The main cause was the presence of preoperative complications (57.5%). Nineteen cases (23.8%) were attributable to anesthesia, with an incidence of 1.11 per 10,000 anesthetic procedures. Survival rate at hospital discharge was 52.5%. The figure for PCA caused by anesthesia was 84.2%. Conclusions: The incidence of PCA and its survival is similar to that reported abroad. In general, PCA has a better prognosis than other types of cardiac arrest, especially if it has an anesthetic cause.

ABSTRACT

ABSTRACT Background: Percutaneous biliary drainage is a safe procedure. The risk of bleeding complications is acceptable. Frequently, patients with biliary obstructions usually have coagulation disorders thus increasing risk of bleeding. For this reason, patients should always fit the parameters of hemostasis. Aim: To determine whether the percentage of bleeding complications in percutaneous biliary drainage is greater in adults with corrected hemostasis prior to the procedure regarding those who did not require any. Methods : Prospective, observational, transversal, comparative by independent samples (unpaired comparison). Eighty-two patients with percutaneous biliary drainage were included. The average age was 64±16 years (20-92) being 38 male and 44 female. Patients who presented altered hemostasis were corrected and the presence of bleeding complications was evaluated with laboratory and ultrasound. Results: Of 82 patients, 23 needed correction of hemostasis. The approaches performed were: 41 right, 30 left and 11 bilateral. The amount of punctures on average was 3±2. There were 13 (15.8%) bleeding complications, 12 (20%) in uncorrected and only one (4.34%) in the corrected group with no statistical difference. There were no differences in side, number of punctures and type of drainage, but number of passes and the size of drainage on the right side were different. There was no related mortality. Conclusion: Bleeding complications in patients requiring hemostasis correction for a percutaneous biliary drainage was not greater than in those who did not require any.


RESUMO Racional: A drenagem biliar percutânea é procedimento seguro. O risco de complicações hemorrágicas é aceitável. Frequentemente, os pacientes com obstruções biliares apresentam distúrbios de coagulação, aumentando o risco de sangramento. Por esse motivo, eles devem sempre ser adequados aos parâmetros da hemostasia. Objetivo: Determinar se a porcentagem de complicações hemorrágicas na drenagem biliar percutânea é maior em adultos com hemostasia corrigida antes do procedimento em relação àqueles que necessitaram nenhuma. Métodos: Estudo prospectivo, observacional, transversal, comparativo por amostras independentes (comparação não pareada). Oitenta e dois pacientes foram submetidos à drenagem biliar percutânea. A idade média foi de 64±16 anos (20-92), 38 eram homens e 44 mulheres. Os pacientes que apresentaram hemostasia alterada foram corrigidos, e a presença de complicações hemorrágicas foi avaliada com exames laboratoriais e ultrassonográficos. Resultados: Dos 82 pacientes, 23 necessitaram de correção da hemostasia. O acesso à direita foi em 41 casos, 30 à esquerda e 11 bilaterais. A quantidade de punções em média foi de 3±2. Houve 13 (15,8%) complicações hemorrágicas, 12 (20%) no grupo não corrigido e apenas uma (4,34%) no corrigido sem diferença estatística. Não houve diferenças no lado, no número de perfurações e no tipo de drenagem, mas o número de passagens e o tamanho da drenagem no lado direito foram diferentes. Não houve mortalidade. Conclusão: As complicações hemorrágicas em pacientes que necessitam de correção da hemostasia antes da drenagem biliar percutânea não são maiores do que naqueles que não a requerem.

ABSTRACT

OBJECTIVE: To evaluate the lower vena cava Collapse Index (CI) as a predictor parameter of hypotensive episodes after general anesthesia induction in ASA I and II patients who were scheduled for elective surgery. MATERIALS AND METHODS: A prospective, observational and simple blind study was designed. A sample of 80 patients was recruited. In the preoperative stage, they underwent protocolarized sedation and CI was obtained. Prior to induction, the baseline values ​​of heart rate, non-invasive mean arterial pressure and continuous electrocardiographic tracing in DII were noted. In the post-orotracheal intubation stage, the aforementioned hemodynamic monitoring variables were recorded manually for 10 minutes. RESULTS: The data of 78 individuals are presented. After anesthetic induction, 8 (10.3%) patients developed hypotension. The adjustment of the univariate logistic regression model for CI shows a good diagnostic capacity, with the area under the ROC curve equal to 0.76. The chance of presenting hypotension is increased by 62% by increasing the CI by 5 points (p = 0.003). Regarding the negative predictive value, we found that with values ​​corresponding to the cutoff points between 39% and 46%, a probability of at least 93.1% of not presenting hypotension was obtained. The optimal cutoff point of the CI to predict hypotension is estimated at 43%, with a sensitivity of 62.5% and a specificity of 92.9%. CONCLUSION: A lower IC was associated with a lower probability of developing intraoperative hypotension. The use of this tool could be useful to anticipate which patients will be prone to intra-surgical hypotension.


OBJETIVO: Evaluar el índice de colapsabilidad (IC) de la vena cava inferior (VCI) como predictor de episodios hipotensivos posinducción de anestesia general en cirugía electiva de pacientes ASA I y II. MATERIALES Y MÉTODOS: Se diseñó un estudio prospectivo, observacional y simple ciego. Se reclutó una muestra de 80 pacientes. En etapa preoperatoria fueron sometidos a una sedación protocolizada y se obtuvo el IC. Previo a la inducción, se anotaron los valores basales de la frecuencia cardíaca, la presión arterial media y el trazado electrocardiográfico continuo en DII. Posintubación orotraqueal, se registraron manualmente las variables hemodinámicas mencionadas durante 10 minutos. RESULTADOS: Se presentan datos de 78 individuos. Luego de la inducción, 8 (10,3%) pacientes desarrollaron hipotensión. El ajuste del modelo de regresión logística univariado para IC muestra una buena capacidad diagnóstica, siendo el área bajo la curva ROC igual a 0,76. La chance de presentar hipotensión se incrementa en un 62% al aumentar el IC en 5 puntos (p = 0,003). En cuanto al valor predictivo negativo, encontramos que con valores correspondientes a los puntos de corte entre 39% y 46%, se obtenía una probabilidad de 93,1% de no presentar hipotensión. El punto de corte óptimo del IC para predecir hipotensión se estima en 43%, con una sensibilidad del 62,5% y una especificidad del 92,9%. CONCLUSIÓN: Un menor IC se asoció con una menor probabilidad de desarrollar hipotensión intraoperatoria. El uso de esta herramienta podría ser de utilidad para anticipar qué pacientes serán propensos a hipotensión intraquirúrgica.

ABSTRACT

Hypercapnia during the intraoperative period is one of the relevant conditions for the anesthesiologist, which can even condition the anesthetic technique, in case of an eventual complication. Where ventilatory monitoring and the interpretation of said disorder allows to diagnose, plan and treat the physiological consequences in the patient. We present the case of a 20 year old patient, scheduled for orthognathic surgery for diagnosis of mandibular body fracture, without added pathologies, no chest trauma, no ventilation disorders. It is presented with the objective of discussing the different considerations to be taken before the progressive establishment of hypercapnia, its causes, consequences and its management.

ABSTRACT

INTRODUCTION: Chronic kidney disease is a clinical entity secondary to the common final pathway of multiple etiologies with risk factors common to other chronic diseases. OBJECTIVE: To identify the risk factors related to the appearance of anesthetic complications in chronic renal patients undergoing emergency surgery. METHOD: A prospective cohort study was performed in patients with chronic kidney disease undergoing emergency surgery. The exposed cohort consisted of 15 patients with chronic kidney disease who developed complications during the study period. RESULTS: Age over 40 years, patients with ischemic heart disease and hypertensive patients presented a higher risk of anesthetic complications. Obesity and bronchial asthma were no risk factors. It was demonstrated that when the time elapsed between hemodialysis and the operation was less than 2 hours, the risk of anesthetic complications increased, the stage of the disease and the associated drugs were not related to the appearance of complications. Patients who received general anesthesia had three times more risk of complications than those under regional anesthesia. CONCLUSIONS: Age, arterial hypertension, ischemic heart disease, heart failure and the use of general anesthesia are risk factors associated with complications.


INTRODUCCIÓN: La enfermedad renal crónica es una entidad clínica secundaria a la vía final común de múltiples etiologías con factores de riesgo comunes a otras enfermedades crónicas. OBJETIVO: Identificar los factores de riesgo relacionados con la aparición de complicaciones anestésicas en enfermos renales crónicos intervenidos de urgencia. MÉTODO: Se realizó un estudio de cohorte prospectivo en pacientes con enfermedad renal crónica intervenidos por cirugía general de urgencia. La cohorte expuesta estuvo constituida por 15 pacientes con enfermedad renal crónica que desarrollaron complicaciones en el período en estudio. RESULTADOS: La edad mayor o igual a 40 años, los pacientes con cardiopatía isquémica y los hipertensos presentaron mayor riesgo de complicaciones anestésicas, no así la obesidad al igual que el asma bronquial. Se demostró que cuando el tiempo transcurrido entre la hemodiálisis y la operación fue inferior a 2 horas se incrementó el riesgo de complicaciones anestésicas, el estadio de la enfermedad y los medicamentos asociados no estuvieron relacionados con la aparición de complicaciones. Los pacientes a los que se administró anestesia general tuvieron tres veces más riesgo de complicaciones que aquellos que fueron intervenidos con anestesia regional. CONCLUSIONES: La edad, la hipertensión arterial, la cardiopatía isquémica, la insuficiencia cardiaca y el empleo de anestesia general son factores de riesgo asociados a complicaciones, en los pacientes portadores de IRC, sometidos a cirugía de urgencia.

ABSTRACT

ABSTRACT Prostatic utricle cyst is a rare congenital anomaly. Symptomatic cysts require treatment. Surgical excision is the treatment of choice, but is challenging due to close proximity to vas deferens, ejaculatory ducts, bladder, prostate, rectum and pelvic nerves. Complications include rectal injury, ureteral injury, impotence, infertility and faecal incontinence. We here report a rare complication in which bladder was accidentally removed during laparoscopic excision of prostatic utricle cyst. To best of our knowledge such a complication has never been reported previously. We also describe the possible cause of this accident and suggest ways to prevent this disastrous complication.

ABSTRACT

Antecedentes. Durante una esofagoscopía en niños, pueden ocurrir complicaciones durante la dilatación. Identificamos alteraciones cardiorrespiratorias durante la esofagoscopía con o sin dilatación con globo y las complicaciones posoperatorias, en niños con anestesia. Métodos. Estudio prospectivo, observacional de procedimientos endoscópicos en niños de 0-16 años. Se dividieron en dos grupos: con endoscopía-dilatación (Grupo ED) y dilatación con globo por estenosis esofágica, y con endoscopía sin dilatación (Grupo E): endoscopía diagnóstica, esofagoscopía de control o escleroterapia. Registramos parámetros hemodinámicos y ventilatorios y las complicaciones durante la endoscopía, la dilatación y el seguimiento de dos horas en la sala de recuperación. Resultados. Incluimos 102 procedimientos en 60 pacientes. La presión inspiratoria máxima (PIM) aumentó significativamente en ambos grupos (p < 0,001) y aumentó significativamente durante el procedimiento en el grupo ED (p < 0,001). La diferencia en la PIM antes y después de la endoscopía se correlacionó negativamente en ambos grupos. Al subdividir los grupos según el punto de corte de 2 años para comparar la diferencia en la PIM antes y después de la endoscopía, la PIM aumentó de manera estadísticamente significativa en ambos grupos en los menores de 2 años. En el grupo ED, la frecuencia cardíaca aumentó estadísticamente significativa (p < 0,001). Conclusión. Durante la endoscopía, la PIM aumentó en niños con o sin dilatación con globo, especialmente en el grupo ED, y fue mayor en los niños más pequeños. Es necesario observar y tratar atentamente las complicaciones cardiorrespiratorias graves durante la dilatación con globo y con anestesia general.


Background. Complications can occur during esophagoscopy as a result of applied procedure in children, especially during dilation techic. Our aim was to identify cardio-respiratory alterations during esophagoscopy with or without baloon dilation under anesthesia in children, and to investigate the postoperative complications. Methods. Prospective, observational study of endoscopic procedures in patients 0-16 years. The patients were divided into two groups: the endoscopy-dilation group (Group ED: endoscopy and balloon dilation due to esophageal stricture) and endoscopy without dilation (Group E: endoscopy for diagnostic reasons, control esophagoscopy or sclerotherapy). Hemodynamic and ventilatory parameters alterations and complications during endoscopy, dilation and two-hours follow-up time in the postoperative recovery room were recorded. Results. 102 procedures in 60 patients were included. Peak inspiratory pressure (PIP) values significantly increased after endoscopy in both groups (p<0.001). There was a significant increase in mean PIP values in the dilation group during the procedure (p<0,001). The difference in PIP values before and after the endoscopy was negatively correlated with age in both groups. When the groups were subdivided taking two years of age as a cut-off point in comparing PIP difference before-after endoscopy, PIP increase was statistically significant in both groups under two-years old. In the dilation group, statistically significant increase of HR was detected during the procedure (p<0,001). Conclusion. During endoscopy PIP increased in patients with or without baloon dilation especially in the dilation group. PIP increase was higher in younger children. Severe respiratory and cardiovascular complications during balloon dilation under general anesthesia should be carefully observed and managed.

ABSTRACT

Abstract Background and objectives Ischemic cardiomyopathy is characterized by imbalance between supply and demand of myocardial oxygen. Endoscopic transthoracic sympathectomy is a therapeutic option indicated in refractory cases. However, the patient's position on the operating table may favor ischemic coronary events triggering the Bezold-Jarisch reflex. Case report A female patient, 47 years old, with refractory ischemic cardiomyopathy, admitted to the operating room for endoscopic transthoracic sympathectomy, developed the Bezold- Jarisch reflex with severe bradycardia and hypotension after placement in semi-sitting position to the procedure. Conclusion Bradyarrhythmia, hypotension, and asystole are complications potentially associated with patient placement in a semi-sitting position, particularly in cases with previous ischemic heart disease.


Resumo Justificativa e objetivos A cardiomiopatia isquêmica caracteriza-se pelo desbalanço entre a oferta e o consumo de oxigênio pelo miocárdio. A simpatectomia transtorácica endoscópica é uma opção terapêutica indicada nos casos refratários. Contudo, a posição do paciente na mesa cirúrgica pode favorecer eventos coronarianos isquêmicos e deflagrar o reflexo de Bezold-Jarisch. Relato de caso Paciente do sexo feminino, 47 anos, portadora de cardiomiopatia isquêmica refratária, admitida na sala de cirurgia para simpatectomia transtorácica endoscópica, deflagrou o reflexo de Bezold-Jarisch e desenvolveu bradicardia e hipotensão graves logo após colocação em posição semissentada para o procedimento. Conclusão Bradiarritmia, hipotensão e assistolia são complicações potencialmente associadas à colocação do paciente em posição semissentada, especialmente nos casos em que há prévio comprometimento isquêmico do coração.

ABSTRACT

Abstract Objective The aim of this study is to report a case of a clinically significant obstruction during mechanical ventilation caused by the dissection of the wired endotracheal tube's lumen during general anesthesia in a pediatric patient. Case report A 12-years old patient undergoing general anesthesia for open appendectomy was intubated with a wired endotracheal tube and difficult removal of the guide. After starting the mechanical ventilation, there was increased expiratory fraction of CO2 and need for increased inspiratory pressure. Chance of complications with higher incidences were raised and treated unsuccessfully. Finally, during patient reintubation, the dissection of the endotracheal tube lumen was observed, and ventilation was restored to normal. Conclusion Anesthesia involves numerous possible complications. Suspicion and constant vigilance are essential for early diagnosis and treatment of any threat to the individual integrity. This case is relevant for emphasizing a possible very rare complication related to airway, which can quickly cause hypoxia and irreversible damage. Thus, this case contributes to the detection of this complication more frequently.


Resumo Objetivo Relatar um caso de obstrução à ventilação mecânica clinicamente significativa causada por dissecção do lúmen do tubo endotraqueal aramado durante anestesia geral em um paciente pediátrico. Relato Paciente de 12 anos submetido à anestesia geral para apendicectomia aberta foi intubado com tubo endotraqueal aramado e retirada de guia do tubo difícil. Após iniciar a ventilação mecânica houve aumento da fração expiratória de CO2 e necessidade de aumento da pressão inspiratória. Hipóteses de complicações com maiores incidências foram aventadas e tratadas sem sucesso. Finalmente, ao reintubar o doente, foi verificada dissecção do lúmen do tubo endotraqueal e a ventilação foi restaurada à normalidade. Conclusão O ato anestésico envolve inúmeras possíveis complicações. A suspeição e a vigilância constantes são essenciais para diagnosticar e tratar precocemente qualquer ameaça à integridade do indivíduo. O presente caso é relevante por enfatizar uma possível complicação muito incomum relacionada às vias aéreas capaz de causar hipóxia e danos irreversíveis rapidamente. Dessa forma, o caso contribui para que essa intercorrência seja detectada com maior frequência.

ABSTRACT

Abstract Tension pneumocephalus is rare but has been well documented following trauma and neurosurgical procedures. It is a surgical emergency as it can lead to neurological deterioration, brainstem herniation and death. Unlike previous cases where tension pneumocephalus developed postoperatively, we describe a case of intraoperative tension pneumocephalus leading to sudden, massive open brain herniation out of the craniotomy site. The possible causative factors are outlined. It is imperative to rapidly identify possible causes of acute intraoperative brain herniation, including tension pneumocephalus, and institute appropriate measures to minimize neurological damage.


Resumo O pneumoencéfalo hipertensivo é raro, mas foi bem documentado após trauma e procedimentos neurocirúrgicos. Trata-se de uma emergência cirúrgica porque pode levar à deterioração neurológica, herniação do tronco cerebral e morte. Ao contrário de casos anteriores, nos quais o pneumoencéfalo hipertensivo se desenvolveu no pós-operatório, descrevemos um caso de pneumoencéfalo hipertensivo desenvolvido no período intraoperatório que levou a uma herniação cerebral súbita, maciça e aberta para fora do local da craniotomia. Os possíveis fatores causais são destacados. É imperativo identificar rapidamente as possíveis causas da herniação cerebral aguda no intraoperatório, incluindo o pneumoencéfalo hipertensivo, e instituir medidas apropriadas para minimizar os danos neurológicos.

ABSTRACT

Las reacciones anafilácticas intraoperatorias son impredecibles, infrecuentes y pueden poner en riesgo al paciente. Tienen una incidencia de 1/10 000 a 1/20 000 produciéndose en la mayoría de los casos por bloqueantes musculares, látex y antibióticos. No hay estadística de las reacciones alérgicas sistémicas durante otros procedimientos médicos. El estudio diagnóstico posterior a una reacción es complejo debiendo incluir toda la medicación utilizada en el procedimiento. En este estudio retrospectivo describimos 15 pacientes, de los cuales 10 tuvieron reacciones anafilácticas en un procedimiento quirúrgico, 2 en endoscopías y 1 en una ecografía transvaginal. Los dos pacientes restantes presentaron una reacción alérgica sistémica durante una ecografía transvaginal y un procedimiento odontológico. Estudiamos los pacientes con toda la medicación utilizada, incluimos látex y, eventualmente, los detergentes y desinfectantes, de haber sido empleados. Tres de las 10 cirugías no pudieron realizarse por desarrollarse la reacción durante la inducción anestésica, en cinco casos debieron interrumpirse y solo en dos se terminaron. Las reacciones posteriores a endoscopías fueron severas, requiriendo internación en terapia intensiva; las reacciones en ecografías transvaginales y procedimientos odontológicos fueron asistidas en emergencias. Los agentes causales en las cirugías incluyeron bloqueantes musculares, látex, cefalosporina, azul patente y ranitidina; en endoscopías el agente causal fue el orto-ftalaldehído (OPA), en las ecografías transvaginales el látex y en el procedimiento odontológico la amoxicilina. El objetivo de este artículo es describir la etiología de las reacciones alérgicas sistémicas y anafilácticas intraoperatorias y en procedimientos médicos, recalcando su gravedad y la necesidad de su identificación.


Anaphylaxis during anesthesia is an unpredictable, severe, and rare reaction. It has an incidence of 1/10 000 to 1/20 000 surgeries. In most series, the responsible drugs include neuromuscular blocking agents, latex, or antibiotics. The frequency and etiology of systemic allergic reactions in other medical procedures are largely unknown. The identification of responsible drugs of anaphylaxis is a complex task, requiring testing of all medications and substances used during surgery. We describe our experience in a retrospective study of 15 patients. Ten subjects developed anaphylaxis during surgery, two in endoscopic studies and one in a trans-vaginal ultrasound. The remaining two subjects, one in a trans-vaginal ultrasound and another during a dental procedure had a systemic allergic reaction. We studied all patients with all medications administered during the procedures, including latex and detergents and disinfectants. Three surgeries had to be suspended at induction of anesthesia, five were stopped incomplete and two were completed. Both patients that presented a reaction during endoscopy required intensive care unit admission and the rest were observed in a Hospital. The responsible drugs during surgery anaphylaxis were neuromuscular blocking agents, latex, patent blue, and ranitidine. Ortho-phthalaldehyde (OPA) was identified during endoscopic studies; latex was responsible in transvaginal ultrasounds; and amoxicillin in the dental procedure. The aim of the present article is to review our experience studying allergic systemic reactions and anaphylaxis during general anesthesia and medical procedures, emphasizing the severity of these reactions and the need for causative drug identification.
