Estudio comparativo en intubación orotraqueal entre anestesiólogos (Quirófano) e intensivistas (Unidad De Terapia Intensiva) en un hospital del Gobierno de la Ciudad de Buenos Aires (GCBA) / Comparative study in orotracheal intubation between anesthesiologists (Operating Room) and intensivists (Intensive Therapy Unit) in a hospital in the Government of the City of Buenos Aires (GCBA), argentina

La intubación orotraqueal (IOT) como otros procedimientos, no se lleva a cabo de igual manera acorde a las distintas especialidades médicas. Para analizar estas diferencias, se han comparado especialistas en terapia intensiva y de anestesiología en diferentes contextos: unidad cerrada y quirófano. Material y Método: Se realizó un estudio de tipo observacional, prospectivo y comparativo con 18 especialistas, 8 anestesiólogos y 10 intensivistas, analizando 20 prácticas de IOT en cada ámbito. Se excluyeron médicos sin especialidad, pacientes menores de 18 años, embarazadas, pacientes con traumatismo cervical y en parada cardiorrespiratoria. Resultados: No se demostraron diferencias en la dificultad en la instrumentación de la vía aérea entre los pacientes intubados por ambas especialidades. Existió mayor utilización de elementos para posicionar la cabeza a favor del grupo de anestesiología (p < 0.05). La pre oxigenación fue utilizada en igual proporción en ambos grupos y el uso de relajantes musculares fue mayor en anestesiologos (p < 0.05). El tiempo de apnea fue superior en los anestesiólogos 58 seg vs 12,8 seg. La técnica de secuencia de intubación rápida fue usada por el 100% de los anestesiólogos contra el 40% de los intensivistas. El éxito y la intubación en un intento fue igual entre los grupos. Las complicaciones: hipoxemia e hipotensión arterial fue mayor entre los intensivistas (p < 0.05). Conclusión La eficacia en la IOT fue igual entre ambos grupos con mayor seguridad en el grupo de anestesiólogos.

Orotracheal intubation (OTI) like other procedures isn´t performed in the same way in different medical specialities. In order to study these differences we have compared the procedure in intensive care units and in operating rooms performed by intensivists and anesthesiologists repectively.. Design: observational, prospective and compared study. Material: 18 specialists, 8 anesthesiologists and 10 intensivists, measuring 20 OTIs in each site. Non-specialist physicians, patients younger than 18 years old, pregnant women, cervical trauma and cardiac arrest patients were excluded. It was approved by the Bioetics Institution Committee. Results: Differences between specialities regarding airway instrumentation difficulty in intubated patients were not observed. More head positioning devices were required by anesthesiologists than by intensivists (p < 0.05). Preoxygenation was used in the same proportion in both groups, whereas neuromuscular blocking drug use was greater among anesthesiologists (p < 0.05). Apnea time was superior in anesthesiologists (58 seconds vs. 12.8 seconds). Rapid sequence intubation technique was used by 100% of anesthesiologists compared to 40% of intensivists. Successful OTI at first attempt was equal between groups. Hypoxemia and arterial hypotension complications were more frequent among intensivists (p < 0.05). Conclusion: OTI effectiveness was equal in both groups, with more safety among anesthesiologists.

OBJECTIVE@#To investigate the baseline levels of microorganisms' growth on the hands of anesthesiologists and in the anesthesia environment at a cancer hospital.@*METHODS@#This study performed in nine operating rooms and among 25 anesthesiologists at a cancer hospital. Sampling of the hands of anesthesiologists and the anesthesia environment was performed at a ready-to-use operating room before patient contact began and after decontamination.@*RESULTS@#Microorganisms' growth results showed that 20% (5/25) of anesthesiologists' hands carried microorganisms (> 10 CFU/cm 2) before patient contact began. Female anesthesiologists performed hand hygiene better than did their male counterparts, with fewer CFUs ( P = 0.0069) and fewer species ( P = 0.0202). Our study also found that 55.6% (5/9) of ready-to-use operating rooms carried microorganisms (> 5 CFU/cm 2). Microorganisms regrowth began quickly (1 hour) after disinfection, and increased gradually over time, reaching the threshold at 4 hours after disinfection. Staphylococcus aureus was isolated from the hands of 20% (5/25) of anesthesiologists and 33.3% (3/9) of operating rooms.@*CONCLUSION@#Our study indicates that male anesthesiologists need to pay more attention to the standard operating procedures and effect evaluation of hand hygiene, daily cleaning rate of the operating room may be insufficient, and we would suggest that there should be a repeat cleaning every four hours.

Research progress on health hazards and occupational protection of prolymethylmethacrylate bone cement in the operating room / 中华劳动卫生职业病杂志

There are many occupational risk factors in operating room work. Polymethyl methacrylate (PMMA) , as a kind of common bone filling and repairing material, is widely used in the fixation of artificial joints, oral braces and orthopedic prosthesis. However, PMMA will release methyl methacrylate (MMA) monomer when it is implanted into human tissues and polymerized to harden, which is toxic to the body. This paper analyzes harmful factors in using PMMA bone cement, and then explores corresponding occupational protection knowledge, in order to reduce the occurrence of occupational hazards related to PMMA bone cement and enhance the self-protection ability of the operation room medical staff.

Time comparison of artificial airway establishment in operating room and on slope using endotracheal intubation and laryngeal mask / 北京大学学报(医学版)

OBJECTIVE@#To compare the completion time of endotracheal intubation and laryngeal mask implantation in operating room and on slope of ski resort, and to discuss the optimal method of estab-lishing artificial airway on slope of ski resort.@*METHODS@#The simulator was placed with the head under the feet on slope of ski resort. The artificial airway was established by tracheal intubation assisted by video laryngoscope (endotracheal intubation group) and laryngeal mask placement (laryngeal mask group) respectively by an anesthesiologist who wore full set of ski suits, helmets, goggles, gloves and ski boots. Each method was repeated 5 times, and the operation time of artificial airway establishment was recorded. While the simulated human was placed flat on the operating table in an operating room of a hospital, and the artificial airway was established by the same anesthesiologist using the same methods. Time was recorded and repeated for 5 times. The completion time of endotracheal intubation and laryngeal mask placement in the operating room and on the ski slope were compared.@*RESULTS@#The operating time of tracheal intubation in the operating room was longer than that of laryngeal mask placement [(79.8±10.4) s vs. (53.4±2.7) s, P=0.005], and the operating time of endotracheal intubation on the ski slope was longer than that of laryngeal mask placement [(209.2±32.7) s vs. (72.2±3.1) s, P=0.001]. The time of endotracheal intubation group on the slope of the ski resort was longer than that in the opera-ting room(t=-7.851, P=0.001). The time of laryngeal mask group on the slope was longer than that in the operating room (t=-19.391, P < 0.001).@*CONCLUSION@#On ski slope, both of tracheal intubation assisted by video laryngoscope and laryngeal mask placement can quickly complete the establishment of artificial airway, but the time required is longer than that in the operating room. The time of laryngeal mask placement to establish artificial airway is shorter than that of tracheal intubation assisted video laryngoscope, which may have a certain advantage in ski rescue.

Applicability of the Disruptions in Surgery Index in the Cardiovascular Management Scenarios - A Marker for Developing Functionally Efficient Teams

Abstract Introduction: To support the development of practices and guidelines that might help to reduce adverse events related to human factors, we aimed to study the response and perception by members of a cardiovascular surgery team of various error-driven or adverse features that might arise in the operating room (OR). Methods: A previously validated Disruptions in Surgery Index (DiSI) questionnaire was completed by individuals working together in a cardiovascular surgical unit. Results were submitted to reliability analysis by calculating the Cronbach's alpha coefficient. Non-parametric Kruskal-Wallis test and Dunn's post-test were performed to estimate differences in perceptions of adverse events or outcomes between the groups (surgeons, nurses, anesthesiologists, and technicians). P<0.05 was considered statistically significant. Results: Cronbach's alpha reliability coefficients showed consistency within the recommended range for all disruption types assessed in DiSI: an individual's skill (0.85), OR environment (0.88), communication (0.81), situational awareness (0.92), patient-related disruption (0.89), team cohesion (0.83), and organizational disruption (0.83). Nurses (27.4%) demonstrated significantly higher perception of disruptions than surgeons (25.4%), anesthetists (23.3%), and technicians (23.0%) (P=0.005). Study participants were more observant of their colleagues' disruptive behaviors than their own (P=0.0001). Conclusion: Our results revealed that there is a tendency among participants to hold a positive self-perception position. DiSI appears to be a reliable and useful tool to assess surgical disruptions in cardiovascular OR teams, identifying negative features that might imperil teamwork and safety in the OR. And human factors training interventions are available to develop team skills and improve safety and efficiency in the cardiovascular OR.

Desarrollo de técnicas microquirúrgicas usando tinción vascular con y sin silicona en placenta humana con modelos craneales 3D / Development of microsurgical techniques using vascular staining with and without silicone in human placenta with 3D cranial models

En las ultimas décadas, ha habido un cambio en la formación en las especialidades quirúrgicas, lo cual ha llevado a plantearse la necesidad de adquisición de habilidades por fuera del quirófano por medio de la simulación. El objetivo de este trabajo es demostrar que el uso de placentas humanas con modelo craneal tridimensional (3D), es un método de alta fidelidad y retroalimentación para el desarrollo de técnicas microquirúrgicas. Se realizó un estudio de evaluación técnica en el Laboratorio de Microcirugía Dr. Evandro de Oliveira del Hospital de la Beneficiencia de Portugal de São Paulo, utilizando 15 placentas con técnicas de coloración y preservación vascular con silicona para moldes; realizando ejercicio de anastomosis vasculares, ejercicios de disección parenquimatosa placentaria que remedan la disección aracnoidea y del valle silviano, además de simulación de resección de tumores. Cualitativamente la placenta humana es un método con alta fidelidad y retroalimentación, además, es de acceso universal para la adquisición de habilidades microquirúrgicas, que asociada a un modelo craneal 3D permite el perfeccionamiento de craneotomías, coordinación visomotriz, propiocepción y relación de profundidad que se requieren para abordajes neuroquirúrgicos.

In the last decades, there has been a change in training in surgical specialties, which has led to the need to acquire skills outside the operating room through simulation. The aim of this work is to demonstrate that the use of human placentas with a three-dimensional (3D) cranial model is a high fidelity and feedback method for the development of microsurgical techniques. A technical evaluation study was carried out in the Dr. Evandro de Oliveira Microsurgery Laboratory of the Hospital de la Beneficiencia de Portugal in São Paulo, using 15 placentas with coloration techniques and vascular preservation with silicone for molds; performing vascular anastomosis, placental parenchymal dissection exercises that mimic arachnoid and sylvian fissure dissection, in addition to simulating tumor resection. Qualitatively, the human placenta is a method with high fidelity and feedback, and it is also universally accessible for the acquisition of microsurgical skills, which, associated with a 3D cranial model, allows the refinement of the craniotomies, visomotor coordination, proprioception, and depth relationship required for neurosurgical approaches.

El abdomen agudo fue el diagnóstico operatorio más frecuente con 98 (58,3 %). Las complicaciones aportaron el 11,9 % de los fallecidos; los eventos adversos, 29,7 %, y por el curso natural de la enfermedad, murió un 58,3 %. El síndrome de disfunción múltiple de órganos y el shock séptico resultaron las principales causas de muerte (62 %). Conclusiones: la mortalidad operatoria estuvo asociada a factores de riesgo como edad avanzada, enfermedades crónicas y cirugía de urgencia. Los eventos adversos elevan la incidencia de mortalidad en cirugía mayor. Las infecciones son la principal causa de mortalidad operatoria (AU).

ABSTRACT Introduction: medical care itself causes, in certain situations, health problems that could be very important for the patient. The mortality analysis is one of the parameters used to study safety performing procedures of major surgery. Objective: to determine the factors associated to operatory mortality in major surgeries. Materials and methods: a retrospective, descriptive and observational study was carried out of the patients who passed away after undergoing a major surgery in the Military Hospital Dr. Mario Munoz Monroy in the period between January 2011 and December 2019. Results: 77.3 % of the deceased were elder people. The main co-morbidities were arterial hypertension, diabetes mellitus and ischemic heart disease. The most frequent surgery diagnosis was acute abdomen with 98 patients (58.3 %). Complications yielded 11.9 % of the deceases, adverse events 29.7 % and 58.3 % died due to the natural course of the disease. The organs multiple dysfunction syndrome and septic shock were the main causes of dead (62 %). Conclusions: operatory mortality was associated to risk factors like advanced age, chronic diseases and emergency surgery. The adverse events increase mortality incidence in major surgery. Infections are the main causes of operatory mortality (AU).

Cancelamento cirúrgico: percepção de enfermeiros do bloco operatório / Surgery cancellation: perception of surgical block nurses / Cancelación quirúrgica: percepción de los enfermeros del quirófano

Objetivo: Identificar a percepção de enfermeiros do bloco operatório sobre os motivos para o cancelamento de cirurgias eletivas e as estratégias para reduzir as taxas de suspensão. Método: Estudo de abordagem qualitativa realizado em um hospital de alta complexidade do Recife, Pernambuco, Brasil, com enfermeiros atuantes no bloco operatório. A coleta de dados foi realizada por meio de entrevistas gravadas com sete enfermeiros responsáveis pelas cirurgias eletivas. Para o tratamento dos dados, utilizou-se a técnica da análise de conteúdo de Bardin. Resultados: Os discursos foram agrupados em duas categorias temáticas: lacunas no planejamento cirúrgico, com três subcategorias, e prevenção de situações evitáveis, com duas subcategorias. Conclusão: Os motivos para o cancelamento de cirurgias estavam relacionados ao planejamento do ambiente cirúrgico e à preparação clínica do paciente. Os enfermeiros identificaram esses motivos como situações evitáveis e consideraram que a comunicação efetiva e atitudes de liderança assertivas são estratégias que reduzem os índices de suspensão cirúrgica.

Objective: To identify the perception of surgical block nurses of the reasons for the cancellation of elective surgeries and strategies to reduce suspension rates. Method: This is a qualitative study carried out in a tertiary hospital of Recife, Pernambuco, Brazil, with nurses working in the surgical block. Data were collected through recorded interviews with seven nurses responsible for elective surgeries. Data treatment was based on Bardin's content analysis technique. Results: The statements were grouped into two thematic categories: gaps in surgical planning, with three subcategories, and prevention of avoidable situations, with two subcategories.

Spinal anesthesia increases the frequency of extubation in the operating room and decreases the time of mechanical ventilation after cardiac surgery

Abstract Introduction: The delayed extubation of patients undergoing mechanical ventilation (MV) in the postoperative period of cardiac surgery (CS) is associated with mortality. The adoption of spinal anesthesia (SA) combined with general anesthesia in CS influences the orotracheal intubation time (OIT). This study aims to verify if the adoption of SA reduces the time of MV after CS, compared to general anesthesia (GA) alone. Methods: Two hundred and seventeen CS patients were divided into two groups. The GA group included 108 patients (age: 56±1 years, 66 males) and the SA group included 109 patients (age: 60±13 years, 55 males). Patients were weaned from MV and, after clinical evaluation, extubated. Results: In the SA group, considering a 13-month period, 24% of the patients were extubated in the operating room (OR), compared to 10% in the GA group (P=0.00). The OIT was lower in the SA group than in the GA group (SA: 4.4±5.9 hours vs. GA: 6.0±5.6 hours, P=0.04). In July/2017, where all surgeries were performed in the GA regimen, only 7.1% of the patients were extubated in the OR. In July/2018, 94% of the surgeries were performed under SA, and 64.7% of the patients were extubated in the OR (P=0.00). The OIT on arrival at the intensive care unit to extubation, comparing July/2017 to July/2018, was 5.3±5.3 hours in the GA group vs. 1.7±3.9 hours in the SA group (P=0.04). Conclusion: The adoption of SA in CS increased the frequency of extubations in the OR and decreased OIT and MV time.
