[The 5-5-2 criteria for biliary cannulation and post endoscopic retrograde cholangiopancreatography complications: Experience in a reference hospital, Peru]. / Criterios 5-5-2 de canulación biliar y complicaciones post colangiopancreatografía retrógrada endoscópica: Experiencia en un hospital de referencia, Perú.

The European Society for Gastrointestinal Endoscopy (ESGE) defines "difficult biliary cannulation" by the presence of one or more of the following: more than 5 contacts with the papilla, more than 5 minutes attempting to cannulate, or inadvertent cannulation of the pancreatic duct in 2 or more times (5-5-2 criteria), recommending these cut-off points to perform advanced cannulation techniques in order to reduce the rate of post-ERCP adverse events. Our objective was to evaluate the performance of the 5-5-2 criteria and their association with post-ERCP complications in a reference hospital in Peru. We performed a prospective analytical case-control study and 120 patients who underwent ERCP were enrolled. The case group included 30 patients who met at least one of the 5-5-2 criteria and the control group included 90 patients without any of these criteria. The ERCP- related complications in both groups and their association with each of the 5-5-2 criteria were compared. The ERCP-related complications that occurred were post-ERCP pancreatitis (6.6% in the case group vs. 3.3% in the control group), bleeding (3.3% controls vs. 0% cases) and perforation (1.1% controls vs. 0% cases); no statistically significant differences were observed. The criterion of 2 or more unintended cannulations to the pancreatic duct showed a significant association (OR= 10.29, CI: 1.47-71.98; p= 0.005) with the incidence of post-ERCP pancreatitis. The criteria 5 minutes and 5 attempts were not associated with post-ERCP complications. In conclusion, among 5-5-2 criteria only the unintended cannulation of 2 or more times into the pancreatic duct was associated with an increased risk of post-ERC pancreatitis. The time and number of attempts criteria could be cautiously expanded without increasing the rate of post-ERCP complications.

Pure Cut or Endocut for Biliary Sphincterotomy? A Multicenter Randomized Clinical Trial.

INTRODUCTION: Adverse events (AE) after endoscopic retrograde cholangiopancreatography (ERCP) are not uncommon and post-ERCP acute pancreatitis (PEP) is the most important one. Thermal injury from biliary sphincterotomy may play an important role and trigger PEP or bleeding. Therefore, this study evaluated the outcomes of 2 electric current modes used during biliary sphincterotomy. METHODS: From October 2019 to August 2021, consecutive patients with native papilla undergoing ERCP with biliary sphincterotomy were randomized to either the pure cut or endocut after cannulation. The primary outcome was PEP incidence. Secondary outcomes included intraprocedural and delayed bleeding, infection, and perforation. RESULTS: A total of 550 patients were randomized (272 pure cut and 278 endocut). The overall PEP rate was 4.0% and significantly higher in the endocut group (5.8% vs 2.2%, P = 0.034). Univariate analysis revealed >5 attempts ( P = 0.004) and endocut mode ( P = 0.034) as risk factors for PEP. Multivariate analysis revealed >5 attempts ( P = 0.005) and a trend for endocut mode as risk factors for PEP ( P = 0.052). Intraprocedural bleeding occurred more often with pure cut ( P = 0.018), but all cases were controlled endoscopically during the ERCP. Delayed bleeding was more frequent with endocut ( P = 0.047). There was no difference in perforation ( P = 1.0) or infection ( P = 0.4999) between the groups. DISCUSSION: Endocut mode may increase thermal injury leading to higher rates of PEP and delayed bleeding, whereas pure cut is associated with increased intraprocedural bleeding without clinical repercussion. The electric current mode is not related to perforation or infection. Further RCT assessing the impact of electric current on AE with overlapping preventive measures such as rectal nonsteroidal anti-inflammatory drugs and hyperhydration are needed. The study was submitted to the Brazilian Clinical Trials Platform ( http://www.ensaiosclinicos.gov.br ) under the registry number RBR-5d27tn.

Independent clinical and echocardiographic predictors of restenosis after percutaneous mitral balloon commissurotomy in a large, consecutive cohort followed for 24 years

OBJECTIVES: to enlighten preprocedural risk factors of mitral valve restenosis in a large, single-center cohort of patients submitted to percutaneous mitral balloon commissurotomy (PMBC) for the treatment of mitral stenosis (MS) secondary to rheumatic heart disease. METHODS: this is a database analysis of a single-center, high-volume tertiary institution involving all consecutive PMBC procedures performed in the mitral valve (MV). Restenosis was diagnosed when MV area was <1.5 cm2 and/or loss of 50% or more of the immediate procedural result aligned with the return/worsened symptoms of heart failure. The primary endpoint was to determine the preprocedural independent predictors of restenosis after PMBC. Results: among a total of 1921 PMBC procedures, 1794 consecutive patients without previous intervention were treated between 1987 and 2010. Throughout 24 years of follow-up, MV restenosis was observed in 483 cases (26%). Mean age was 36 years and most (87%) were female. Median follow-up duration was 9.03 years (interquartile range, 0.33-23.38). Restenosis population, however, presented a significantly lower age at the procedure time as well as a higher Wilkins-Block score. At multivariate analysis, independent preprocedure predictors of restenosis were left atrium diameter (hazard risk [HR], 1.03; 95% confidence interval [CI], 1.02-1.05; P<.04), preprocedure maximum gradient (HR, 1.02; 95% CI, 1.00-1.03; P=.04), and higher Wilkins-Block score (>8) (HR, 1.38; 95% CI, 1.14-1.67; P<.01). CONCLUSIONS: at long-term follow-up, MV restenosis was observed in a quarter of the population undergoing PMBC. Preprocedure echocardiographic findings, including left atrial diameter, maximum MV gradient, and Wilkins-Block score were found to be the only independent predictors.

Minimally invasive therapy for the resolution of a subcapsular hepatic hematoma in a newborn. / Terapia mínimamente invasiva para el manejo de un hematoma subcapsular hepático en un recién nacido.

OBJECTIVE: To describe an innovative alternative to exploratory laparotomy in a newborn with a sub capsular hepatic hematoma secondary to umbilical vein catheterization. CLINICAL CASE: A preterm baby with a history of hyaline membrane disease, pulmonary hypertension, and large patent ductus arteriosus, requiring mechanical ventilation and the use of vasoactive drugs. Umbilical catheters were inserted and through an abdomen X-ray, we observed their proper position. The patient evolved with greater requirements of vasoactive drugs, abdominal wall pallor, and abdominal distention. Abdominal ultrasound showed a subcapsular hepatic hematoma, with no signs of active bleeding, so expectant management was decided. The patient required increased vasoactive drugs and presented a decrease in hematocrit. New ultrasound showed a larger subcapsular hematoma, abundant perihe patic fluid, and the intraparenchymal position of the umbilical catheter was confirmed. Endovascular embolization was performed through the umbilical catheter with Gelita®, achieving occlusion of the capsular path. Posterior ultrasound showed a reduction of the hematoma. CONCLUSIONS: The use of embolization through angiography is not commonly used in pediatric emergencies. It is a procedure with fewer comorbidities and complications than exploratory laparotomy, therefore it should be considered as first-line therapy in patients like the one presented above. The limitation for its routine performance is the lack of available angiography operating room and trained interventional radio logy team.

Endoscopic Biliary Large Balloon Dilation Lithotripsy for Giant and Impacted Stones Removal: A Western Series.

BACKGROUND: Endoscopic removal of packed, large, or impacted stones, in which a basket cannot be deployed or is unable to grasp the stone(s), is challenging and inevitably leads to repeated procedures such as stent insertion and extra- or intracorporal lithotripsy. In this study, we describe the results of an alternative stone disintegration technique in a considerable series of patients using an esophageal/pyloric balloon for stone fragmentation or making working space in the bile duct to allow the deployment of the basket, a technique we call endoscopic biliary large balloon lithotripsy. METHODS: We retrieved data from 1,429 endoscopic retrograde cholangiopancreatographies (ERCPs) from 2 prospective trials performed between 2014 and 2019. Patients with difficult bile duct stones, in which a balloon dilator up to 15 mm was used to crush or increase the working space parallel to the stones in the common or hepatic duct, were included in the study. RESULTS: From the 1,429 ERCPs, 299 had difficult stones (>1 cm, impacted or multiple stones). Large balloon lithotripsy was employed in 46 cases after endoscopic papillotomy and endoscopic biliary large balloon dilation with failed attempted balloon or basket stone(s) extraction. Failure to clear the bile duct at first ERCP occurred in 4 cases (91.3% of success). Complications were observed in 5 patients (10.8%; 1 perforation, 1 pancreatitis, and 3 bleedings), who were treated conservatively. CONCLUSIONS: Large balloon lithotripsy, in order to crush the stones or make working room for baskets or balloons in the bile duct, is an effective, safe, and low cost technique for impacted, packed, or giant bile duct stones.

Flushing na manutenção de cateteres intravenosos: um estudo observacional da prática de enfermagem na terapia intensiva / Flushing in the maintenance of intravenous catheters: an observational study of nursing practice in intensive care

A manutenção da permeabilidade do cateter intravenoso usado em pacientes hospitalizados é essencial para prevenir danos e garantir a segurança da terapia intravenosa. Dentre os cuidados de enfermagem preconizados para essa manutenção está o flushing, que é a aplicação de solução salina no lúmen do cateter com o objetivo de limpeza. Essa pesquisa teve como objetivos: Caracterizar a prática da equipe de enfermagem na realização do flushing para a manutenção de cateteres intravenosos utilizados por pacientes hospitalizados em cenários de cuidados intensivos; Avaliar a associação de características profissionais da equipe de enfermagem com a prática do flushing na manutenção de cateteres intravenosos em pacientes hospitalizados em cenários de cuidados intensivos; Analisar a prática do flushing em relação às melhores evidências para a manutenção dos cateteres intravenosos, na perspectiva da segurança do paciente; Elaborar, à luz dessa análise, uma tecnologia de cuidado voltada a promover as boas práticas de enfermagem na realização do flushing para a manutenção dos cateteres intravenosos. Estudo observacional, transversal e com abordagem quantitativa, realizado em quatro cenários de cuidados intensivos de um hospital universitário do município do Rio de Janeiro. Participaram 108 profissionais de enfermagem que realizavam a manutenção dos dispositivos intravenosos e estavam envolvidos na prática do flushing. Os dados foram coletados através de observação por meio checklist e aplicação de questionário estruturado, no período de novembro de 2019 a janeiro de 2020. A análise ocorreu por meio de estatística descritiva, analítica e inferencial. Foram realizadas 404 observações da prática do flushing, das quais em 23% não houve a realização do flushing e, em 77%, a prática do flushing foi realizada em algum momento da manipulação do dispositivo intravenoso. Das observações em que houve algum momento de flushing, em 52% os profissionais utilizaram frasco de grande volume no preparo; 97% utilizaram solução fisiológica; 70% aplicaram a técnica de pressão contínua no êmbolo da seringa; 64,5% não avaliaram previamente a permeabilidade. Houve predomínio da prática do flushing após a administração de medicamentos, com emprego do volume e seringa de 10 ml. Possuir formação específica ligada a acesso venoso, conhecimento de guidelines e tempo de exercício profissional inferior a cinco anos foram variáveis que aumentaram as chances de realização do flushing na prática. Quanto aos dados do questionário: 88% dos participantes responderam que efetuam o procedimento do flushing na sua prática; 93% descreveram o soro fisiológico como a solução de escolha; 49,5% relataram realizar o flushing com a pressão contínua no êmbolo da seringa, enquanto 35% aplicam a técnica push pause. No que tange à frequência, apenas 22% referiram que realizam o flushing antes, entre e após a administração de um medicamento. Entretanto, quando essa frequência foi graduada numa escala, nos dados do cateter venoso central, principal dispositivo manipulado na prática, 64% referiram que realizam muitas vezes/sempre o flushing antes da administração do medicamento, 68% realizam muitas vezes/sempre entre a administração dos medicamentos e 79% realizam muitas vezes/sempre após a administração. Concluiu-se que existiram fragilidades na prática do flushing em relação às recomendações de boas práticas que se configuram erros de medicação. Esses resultados indicam a necessidade de investimentos em melhorias nos cenários estudados em vista das boas práticas na terapia intravenosa. Em face disso, elaborou-se uma tecnologia na forma de guia de cuidado para a prática do flushing, a ser implementada na instituição como uma barreira à recorrência dos erros.

Maintaining the patency of the intravenous catheter used in hospitalized patients is essential to prevent damage and ensure the safety of intravenous therapy. Among the nursing care recommended for this maintenance is flushing, which is the application of saline solution in the lumen of the catheter with the objective of cleaning. This research aimed to: Characterize the practice of the nursing team in performing flushing for the maintenance of intravenous catheters used by hospitalized patients in intensive care settings; To evaluate the association of professional characteristics of the nursing team with the practice of flushing in the maintenance of intravenous catheters in hospitalized patients in intensive care settings; To analyze the practice of flushing in relation to the best evidence for the maintenance of intravenous catheters, from the perspective of patient safety; To develop, in the light of this analysis, a care technology aimed at promoting good nursing practices in performing flushing for the maintenance of intravenous catheters. Observational, cross-sectional study with a quantitative approach, carried out in four intensive care settings at a university hospital in the city of Rio de Janeiro. Participants were 108 nursing professionals who performed the maintenance of intravenous devices and were involved in the practice of flushing. Data were collected through observation using a checklist and application of a structured questionnaire, from November 2019 to January 2020. The analysis was carried out using descriptive, analytical and inferential statistics. A total of 404 observations of flushing were performed, of which 23% did not perform flushing and, in 77%, flushing was performed at some point during the handling of the intravenous device. Of the observations in which there was some moment of flushing, in 52% the professionals used a large volume bottle in the preparation; 97% used saline solution; 70% applied the technique of continuous pressure on the plunger of the syringe; 64.5% had not previously evaluated permeability. There was a predominance of flushing after drug administration, using the volume and 10 ml syringe. Having specific training related to venous access, knowledge of guidelines and time of professional practice of less than five years were variables that increased the chances of performing flushing in practice. As for the data from the questionnaire: 88% of the participants answered that they perform the flushing procedure in their practice; 93% described saline as the solution of choice; 49.5% reported flushing with continuous pressure on the syringe plunger, while 35% applied the push pause technique. Regarding the frequency, only 22% reported that they perform flushing before, between and after the administration of a medication. However, when this frequency was graded on a scale, in the data of the central venous catheter, the main device manipulated in practice, 64% reported that they often/always perform flushing before drug administration, 68% perform it often/always between administration of medications and 79% perform it often/always after administration. It was concluded that there were weaknesses in the practice of flushing in relation to the recommendations of good practices that configure medication errors. These results indicate the need for investments in improvements in the scenarios studied in view of good practices in intravenous therapy. In view of this, a technology was developed in the form of a care guide for the practice of flushing, to be implemented in the institution as a barrier to the recurrence of errors.

Mantener la permeabilidad del catéter intravenoso utilizado en pacientes hospitalizados es esencial para prevenir daños y garantizar la seguridad de la terapia intravenosa. Entre los cuidados de enfermería recomendados para ese mantenimiento está el flushing, que es la aplicación de solución salina en la luz del catéter con el objetivo de limpiarlo. Esta investigación tuvo como objetivo: Caracterizar la práctica del equipo de enfermería en la realización de lavados para el mantenimiento de los catéteres intravenosos utilizados por pacientes hospitalizados en cuidados intensivos; Evaluar la asociación de las características profesionales del equipo de enfermería con la práctica de lavado en el mantenimiento de catéteres intravenosos en pacientes hospitalizados en cuidados intensivos; Analizar la práctica del flushing en relación a la mejor evidencia para el mantenimiento de catéteres intravenosos, desde la perspectiva de la seguridad del paciente; Desarrollar, a la luz de este análisis, una tecnología asistencial dirigida a promover buenas prácticas de enfermería en la realización de lavados para el mantenimiento de catéteres intravenosos. Estudio observacional, transversal, con abordaje cuantitativo, realizado en cuatro unidades de cuidados intensivos de un hospital universitario de la ciudad de Rio de Janeiro. Participaron 108 profesionales de enfermería que realizaban el mantenimiento de los dispositivos intravenosos y participaban en la práctica del flushing. Los datos fueron recolectados a través de la observación mediante una lista de cotejo y aplicación de un cuestionario estructurado, de noviembre de 2019 a enero de 2020. El análisis se realizó mediante estadística descriptiva, analítica e inferencial. Se realizaron un total de 404 observaciones de lavado, de las cuales el 23% no realizó lavado y en el 77% se realizó lavado en algún momento durante la manipulación del dispositivo intravenoso. De las observaciones en las que hubo algún momento de rubor, en 52% los profesionales utilizaron un biberón de gran volumen en la preparación; 97% utilizó solución salina; el 70% aplicó la técnica de presión continua sobre el émbolo de la jeringa; El 64,5% no había evaluado previamente la permeabilidad. Predominó el rubor tras la administración del fármaco, utilizando el volumen y jeringa de 10 ml. Tener formación específica relacionada con el acceso venoso, el conocimiento de las guías y un tiempo de ejercicio profesional inferior a cinco años fueron variables que aumentaron las posibilidades de realizar lavados en la práctica. En cuanto a los datos del cuestionario: el 88% de los participantes respondieron que realizan el procedimiento de lavado en su práctica; el 93% describió la solución salina como la solución de elección; El 49,5% refirió enjuagar con presión continua sobre el émbolo de la jeringa, mientras que el 35% aplicó la técnica de empujar pausa. En cuanto a la frecuencia, solo el 22% informó que realiza lavados antes, entre y después de la administración de un medicamento. Sin embargo, cuando se graduó esta frecuencia en una escala, en los datos del catéter venoso central, el principal dispositivo manipulado en la práctica, el 64% informó que a menudo/siempre realiza lavado antes de la administración del medicamento, el 68% lo realiza a menudo/siempre entre administración de medicamentos y el 79% lo realiza seguido/siempre después de la administración. Se concluyó que existieron debilidades en la práctica del flushing en relación a las recomendaciones de buenas prácticas que configuran errores de medicación. Estos resultados indican la necesidad de inversiones en mejoras en los escenarios estudiados en vista de las buenas prácticas en terapia intravenosa. Ante esto, se desarrolló una tecnología en forma de guía de cuidados para la práctica del rubor, para ser implementada en la institución como barrera a la reincidencia de errores.

Risk Factors for Success, Complications, and Death after Endoscopic Sphincterotomy for Bile Duct Stones: A 17-Year Experience with 2,137 Cases.

BACKGROUND: Risk factors for post-endoscopic retrograde cholangiopancreatography (ERCP) complications are well-studied. However, risk factors for complications and success after endoscopic sphincterotomy (EST) for duct stones are poorly determined. This study aimed to verify risk factors for mortality, complications, and success after EST. METHODS: A multivariate analysis was carried out in a dataset of ERCPs performed during 17 years. RESULTS: A total of5,226 ERCPs were performed, of which 2,137 were in patients with bile duct stones (1,458 women and 679 men; mean age = 57 years) who underwent EST with attempted stone removal. There were 171 (8%) complications, with pancreatitis in 87 (4.1%), bleeding in 48 (2.2%), other complications in 36 (1.8%), and mortality of 0.6%. Successful stone(s) removal was obtained in 2,028 cases (94.9%). On multivariate analysis, mortality was associated with age >60 years (1 vs. 0.2%), cholangitis (4.3 vs. 0.3%), and EST-related complications (5.8 vs. 0.2%). Complications were associated with unsuccessful stone removal (13.4 vs. 7.5%) and difficult cannulation (13.9 vs. 5.4%). An unsuccessful EST was independently related to difficult cannulation (86.2 vs. 98.7%), precutting (79.4 vs. 96.4%), and complications (86.5 vs. 95.6%). CONCLUSIONS: Risk factors for complications after EST for stones are delayed bile duct cannulation and failed stone retrieval. Mortality is higher in older patients, those who presented with an EST-related complication, or those who presented initially with cholangitis. Difficult cannulation, EST-related complications, and precutting were associated with an unsuccessful procedure. In this series, outpatient EST with attempted stone retrieval was found to be as safe as performing the procedure in hospitalized patients.

Analgesic efficacy of 10% lidocaine spray during nasoenteral catheterization: Randomized triple-blind trial.

BACKGROUND: Pain is a common experience during nasoenteral catheterization. Although the procedure causes discomfort and distress to patients, procedural pain remains neglected and undertreated. OBJECTIVE: To evaluate the analgesic efficacy of the use of 10% lidocaine spray during nasoenteral catheterization. METHOD: A randomized, triple-blind trial of 50 patients was performed. The patients were randomly assigned to two groups: an intervention group (IG), in which 10% lidocaine spray combined with 2% lidocaine gel was used, and a control group (CG), in which a saline solution spray combined with 2% lidocaine gel was used. Pain and discomfort were assessed during and after nasoenteral catheterization using numerical rating scale (NRS) and the visual analogue scale (VAS), respectively. RESULTS: Intervention group participants reported lower pain scores during (0.20 ± 0.71 vs. 5.00 ± 2.84, p < .001; |d| = -0.677) and after (0.00 ± 0.00 vs. 2.80 ± 2.83, p < .001; |d| = -0.718) nasoenteral catheterization compared to the CG. CONCLUSION: Spraying 10% lidocaine spray before nasoenteral catheterization was most effective for relieving discomfort and pain, with lower pain and discomfort recorded in NRS and VAS. Topical administration of 10% lidocaine spray is therefore a suggested measure for procedural pain relief related to nasoenteral catheterization. SIGNIFICANCE: The use of 10% lidocaine spray was more effective in relieving procedural pain and discomfort during nasoenteral catheterization. Patients who received 10% lidocaine spray registered lower discomfort and pain scores than those from 2% lidocaine gel group; there were less complications among patients in the IG.

Canulación biliar difícil: precorte precoz tipo fistulotomía para evitar la pancreatitis post CPRE. Un análisis retrospectivo de dos años / Difficult biliary cannulation: early precut fistulotomy to avoid post ERCP pancreatitis. A retrospective analysis for two years

Antecedentes: La canulación biliar difícil es un factor de riesgo para la pancreatitis post-CPRE. En estos casos el precorte es la técnica más usada. Objetivo: Demostrar que el precorte tipo fistulotomía es seguro y eficaz. Materiales y métodos: Se revisaron los datos de mayo de 2016 a mayo de 2018. Se definió canulación difícil como: litiasis impactada, canulación inadvertida del conducto pancreático en tres ocasiones e incapacidad para lograr la canulación en 3 minutos. Las medidas de resultados fueron la canulación biliar exitosa y la pancreatitis post-CPRE. Resultados: Se realizó precorte tipo fistulotomía en 96 casos (67 mujeres, 29 hombres). La tasa de éxito de la canulación biliar fue del 95,8% (92/96). Ochenta pacientes tenían factores de riesgo para pancreatitis post CPRE: 29 tuvieron un solo factor de riesgo, 26 tuvieron dos, 19 tuvieron tres y 6 tuvieron cuatro. Factores de riesgo ampulares de canulación difícil: calculo impactado 9 casos, abultamiento de la papila en 10 casos, ubicación inferior del orificio papilar en 38 casos, localización parcial del poro papilar en 23 y estenosis del orificio papilar en 16 casos. Diez pacientes tuvieron divertículo periampular, 7 pacientes tuvieron conducto biliar normal. Ninguno de los pacientes experimentó pancreatitis. Tres pacientes tuvieron sangrado precoz, una paciente presento sangrado tardío. Un paciente (2%) tuvo fiebre y fue hospitalizado. Conclusiones: En casos de canulación biliar difícil el precorte tipo fistulotomía es seguro y eficaz.

Background: Difficult biliary cannulation is a risk factor for post-ERCP pancreatitis. In these cases, precutting is the most used technique. Objective: To demonstrate that precut fistulotomy is safe and effective. Materials and methods: Data from May 2016 to May 2018 were reviewed. Difficult cannulation was defined as: impacted lithiasis, inadvertent cannulation of the pancreatic duct on three occasions and inability to achieve deep biliary cannulation in 3 minutes. The outcome measures were successful biliary cannulation and post-ERCP Pancreatitis. Results: Precut fistulotomy was performed in 96 cases (67 women, 29 men). The success rate of biliary cannulation was 95.8% (92/96). Eighty patients had risk factors for post-ERCP pancreatitis: 29 had 1 risk factor, 26 had 2 risk factors, 19 had 3 risk factors, and 6 had four risk factors. Ampullary risk factors of difficult cannulation: impacted stone in the papilla: 9 cases, papilla bulging: 10 cases, lower location of the hole papillary 38 cases, partial location of the papillary pore 23 and papillary orifice stenosis 16 cases. Ten patients had periampullary diverticulum, 7 patients had normal bile duct. None of the patients experienced Pancreatitis. Three patients had early bleeding, one patient had late bleeding. One patient (2%) had a fever and was hospitalized. Conclusions: In cases of difficult biliary cannulation, the precut fistulotomy is safe and effective.

Virtual Reality for Pediatric Needle Procedural Pain: Two Randomized Clinical Trials.

OBJECTIVE: To assess the efficacy and safety of a virtual reality distraction for needle pain in 2 common hospital settings: the emergency department (ED) and outpatient pathology (ie, outpatient laboratory). The control was standard of care (SOC) practice. STUDY DESIGN: In 2 clinical trials, we randomized children aged 4-11 years undergoing venous needle procedures to virtual reality or SOC at 2 tertiary Australian hospitals. In the first study, we enrolled children in the ED requiring intravenous cannulation or venipuncture. In the second, we enrolled children in outpatient pathology requiring venipuncture. In the ED, 64 children were assigned to virtual reality and 59 to SOC. In pathology, 63 children were assigned to virtual reality and 68 to SOC; 2 children withdrew assent in the SOC arm, leaving 66. The primary endpoint was change from baseline pain between virtual reality and SOC on child-rated Faces Pain Scale-Revised. RESULTS: In the ED, there was no change in pain from baseline with SOC, whereas virtual reality produced a significant reduction in pain (between-group difference, -1.78; 95% CI, -3.24 to -0.317; P = .018). In pathology, both groups experienced an increase in pain from baseline, but this was significantly less in the virtual reality group (between-group difference, -1.39; 95% CI, -2.68 to -0.11; P = .034). Across both studies, 10 participants experienced minor adverse events, equally distributed between virtual reality/SOC; none required pharmacotherapy. CONCLUSIONS: In children aged 4-11 years of age undergoing intravenous cannulation or venipuncture, virtual reality was efficacious in decreasing pain and was safe.

Innominate vs. axillary artery cannulation in aortic surgery: a systematic review and meta-analysis

Abstract Objective: To investigate whether axillary artery cannulation has supremacy over innominate artery cannulation in thoracic aortic surgery. Methods: A comprehensive search was undertaken among the four major databases (PubMed, Excerpta Medica dataBASE [EMBASE], Scopus, and Ovid) to identify all randomized and nonrandomized controlled trials comparing axillary to innominate artery cannulation in thoracic aortic surgery. Databases were evaluated and assessed up to March 2017. Results: Only three studies fulfilled the criteria for this meta-analysis, including 534 patients. Cardiopulmonary bypass time was significantly shorter in the innominate group (P=0.004). However, the innominate group had significantly higher risk of prolonged intubation > 48 hours (P=0.04) than the axillary group. Further analysis revealed no significant difference between the innominate and axillary groups for deep hypothermic circulatory arrest time (P=0.06). The relative risks for temporary and permanent neurological deficits as well as in-hospital mortality were not significantly different for both groups (P=0.90, P=0.49, and P=0.55, respectively). Length of hospital stay was similar for both groups. Conclusion: There is no superiority of axillary over innominate artery cannulation in thoracic aortic surgery in terms of perioperative outcomes; however, as the studies were limited, larger scale comparative studies are required to provide a solid evidence base for choosing optimal arterial cannulation site.

Risk factors associated with late-onset neonatal sepsis / Factores de riesgo asociados a sepsis neonatal tardía

Background: Sepsis is one of the main causes of morbidity and mortality in neonates. Objective: To identify the risk factors for neonatal sepsis in a neonatal unit from March to October, 2016. Methods: Case-control study. The factors analyzed were: a) neonatal factors such as: type of delivery, sex, birth weight, gestational age, criteria for systemic inflammatory response syndrome, type of sepsis (early or late) and blood culture result; B) invasive methods such as: central catheterization, total parenteral nutrition, umbilical catheterization and mechanical ventilation; C) maternal factors such as: number of prenatal controls, infection during pregnancy, premature rupture of membranes, maternal age and maternal fever. Odds Ratio was used to determine association. Results: For the development of early-onset sepsis, significant risk factors were: thermodynamic imbalance, tachycardia and maternal fever. With regard to late-onset sepsis, significant associations were found for thermodynamic imbalance, umbilical catheterization, mechanical ventilation and insufficient prenatal care. Conclusions: Thermodynamic imbalance, tachycardia, mechanical ventilation, umbilical catheterization, maternal fever, and insufficient prenatal care were the probable risk factors associated with neonatal sepsis.

Introducción: la sepsis es una de las principales causas de morbimortalidad en neonatos. Objetivo: identificar los factores de riesgo para sepsis neonatal en una unidad de neonatología durante los meses de marzo a octubre del año 2016. Métodos: estudio de casos y controles. Los factores analizados fueron: a) factores neonatales como: tipo de parto, sexo, peso al nacimiento, edad gestacional, criterios de síndrome de respuesta inflamatoria sistémica, tipo de sepsis (temprana o tardía) y resultado de hemocultivo; b) métodos invasivos como: cateterismo central, nutrición parenteral total, cateterismo umbilical y ventilación mecánica y; c) factores maternos como: número de controles prenatales, infección durante el embarazo, ruptura prematura de membranas, edad materna y fiebre materna. Se utilizó razón de momios (RM) para determinar asociación. Resultados: para el desarrollo de sepsis temprana, los factores de riesgo significativos fueron: el desequilibrio termodinámico, la taquicardia y la fiebre materna. Respecto a la sepsis tardía se encontraron asociaciones significativas para el desequilibrio termodinámico, el uso de cateterismo umbilical, la ventilación mecánica y los controles prenatales insuficientes. Conclusión: el desequilibrio termodinámico, la taquicardia, la ventilación mecánica, el cateterismo umbilical, la fiebre materna y los controles prenatales insuficientes fueron los probables factores de riesgo significativos asociados a sepsis neonatal.

[Difficult biliary cannulation: early precut fistulotomy to avoid post ERCP pancreatitis. A retrospective analysis for two years]. / Canulación biliar difícil: precorte precoz tipo fistulotomía para evitar la pancreatitis post CPRE. Un análisis retrospectivo de dos años.

BACKGROUND: Difficult biliary cannulation is a risk factor for post-ERCP pancreatitis. In these cases, precutting is the most used technique. OBJECTIVE: To demonstrate that precut fistulotomy is safe and effective. MATERIALS AND METHODS: Data from May 2016 to May 2018 were reviewed. Difficult cannulation was defined as: impacted lithiasis, inadvertent cannulation of the pancreatic duct on three occasions and inability to achieve deep biliary cannulation in 3 minutes. The outcome measures were successful biliary cannulation and post-ERCP Pancreatitis. RESULTS: Precut fistulotomy was performed in 96 cases (67 women, 29 men). The success rate of biliary cannulation was 95.8% (92/96). Eighty patients had risk factors for post-ERCP pancreatitis: 29 had 1 risk factor, 26 had 2 risk factors, 19 had 3 risk factors, and 6 had four risk factors. Ampullary risk factors of difficult cannulation: impacted stone in the papilla: 9 cases, papilla bulging: 10 cases, lower location of the hole papillary 38 cases, partial location of the papillary pore 23 and papillary orifice stenosis 16 cases. Ten patients had periampullary diverticulum, 7 patients had normal bile duct. None of the patients experienced Pancreatitis. Three patients had early bleeding, one patient had late bleeding. One patient (2%) had a fever and was hospitalized. CONCLUSIONS: In cases of difficult biliary cannulation, the precut fistulotomy is safe and effective.

Comparative Analysis of Adverse Events After Esophageal Balloon and Bougie Dilations in Children.

BACKGROUND: Pneumatic balloon and bougie dilation are widely used methods for pediatric esophageal dilation. There are no studies directly comparing the safety of these techniques in pediatric patients. This study compared adverse events (AEs) of balloon and bougie dilation in children at a single institution. METHODS: AEs were identified by means of a prospective clinical registry of all procedure related AEs from 2012 to 2015 at a single institution. Identified AEs underwent retrospective review of procedural and clinical details. The category of each AE was recorded and severity was assigned using a 5-point scoring system. AEs were compared between balloon and bougie dilation for different severities. RESULTS: There were 105 patients who underwent 246 dilation sessions. Balloon dilation was performed more commonly (n = 190, 77%) as compared to Maloney dilators (n = 56, 23%). Patients with balloon dilation were younger (3.0 vs 14.5 years, P = 0.0001) and more likely to have strictures from caustic ingestion (42% vs 2%, P < 0.0001) or surgical anastomoses (34% vs 5% P < 0.0001). Bougie dilation was used more commonly in patients with eosinophilic esophagitis (77% vs 7%, P < 0.0001)). In multivariate analysis, each year of increasing age was associated with a 12% increase in any AEs (P = 0.015), but no difference in clinically significant AEs (grade 2 or higher) was identified between dilation methods. CONCLUSIONS: Bougie and balloon dilation did not have significant differences in AE rates, but the patient populations differed between the 2 methods. The dilation method should depend on stricture characteristics and endoscopist expertise with each method.
