Nursing evaluation of pediatric preoperative anxiety: a qualitative study / Avaliação de enfermagem da ansiedade pré-operatória pediátrica: um estudo qualitativo? / Evaluación enfermera de la ansiedad prequirúrgica pediátrica: estudio cualitativo

Abstract Objective: to explore and describe how perioperative nurses assess and interpret the child's behavior before entering the operating room, identifying the strategies they use to reduce anxiety and the proposals for improvements. Method: descriptive qualitative study using semi-structured interviews and participant observation of daily routines. Thematic analysis of data. This study follows the recommended criteria for publication of articles of the qualitative methodology Consolidated Criteria for Reporting Qualitative Research. Results: four topics emerged from the data: a) assessment of anxiety or close communication with the child and their family; b) evaluating what was observed; c) managing anxiety and d) improving the assessment or proposals for improvements in daily practice. Conclusion: nurses assess anxiety in their daily practice through observation using their clinical judgment. The nurse's experience is decisive for the appropriate assessment of the preoperative anxiety in child. Insufficient time between waiting and entering the operating room, lack of information from child and their parents about the surgical procedure, and parental anxiety make it difficult to assess and properly manage anxiety.

Anesthesia and breastfeeding / Lactancia materna y anestesia

Abstract The importance of breastfeeding with its positive impact on the wellbeing of the mother-infant pair is well established. Anesthesiologists should encourage the promotion of lactation by being willing to give reassurance during the preoperative period and preparing a plan that does not interfere with safe breastfeeding. There is concern regarding the transfer of drugs into breast milk, which may lead to inconsistent advice from many health professionals and to early discontinuation. However, evidence shows that most anesthetic drugs are safe in terms of transfer into breast milk, and hence, compatible with breastfeeding, which should be resumed after anesthesia as soon as the mother is alert and feels well enough to hold her infant, without the need to "pump and dump". This review provides pharmacokinetic information on commonly used anesthesia drugs and their passage into breast milk, to help practitioners discuss risks and benefits with the mother, emphasizing that anesthesia should not interfere with the benefits of breastfeeding. Four practical clinical scenarios are presented: pregnant women concerned about the effect of epidural analgesia on subsequent breastfeeding, spinal anesthesia for c-section and lactation, patients who will receive general anesthesia during cesarean section, and finally women who are breastfeeding and require anesthesia for elective or urgent surgery. Neuraxial anesthesia allows for better pain control and immediate skin-to-skin contact at the time of childbirth. Also, it interferes the least with the woman's ability to care for her infant. Regional techniques, opioid-sparing techniques and outpatient surgery are preferred. Drugs such as opioids and longer-acting benzodiazepines should be administered cautiously, particularly in repeat doses.

Resumen La lactancia materna tiene evidentes beneficios para el binomio maternofetal. El anestesiólogo debe ser un agente en la promoción de la lactancia, estar dispuesto a resolver dudas en el preoperatorio y elaborar un plan que no interfiera con su seguridad. Hay preocupación referente a la transferencia de los medicamentos (endovenosos y/o neuroaxiales) hacia la leche, que puede conducir a un consejo inconsistente de muchos profesionales de la salud, lo cual contribuye a la suspensión temprana de la lactancia materna. Sin embargo, existe evidencia de que la mayoría de los medicamentos que se utilizan en la anestesia (general y neuroaxial) son compatibles con la lactancia materna. Se debe iniciar la lactancia materna después de la anestesia tan pronto como la madre esté alerta y se sienta bien, sin necesidad de extraerla y eliminarla. Esta revisión entrega información farmacocinética sobre los medicamentos y técnicas anestésicas comúnmente utilizadas para que los profesionales realicen un balance riesgo-beneficio con la madre, enfatizando que la anestesia no debe interferir con los beneficios de la lactancia. Se presentan cuatro escenarios clínicos prácticos: embarazada preocupada por el efecto de la analgesia peridural en su lactancia posterior, anestesia raquídea para cesárea y efecto en lactancia, pacientes que requieren anestesia general para cesárea y, por último, paciente puérpera que requiere anestesia para cirugía. Las técnicas neuroaxiales permiten un mejor control del dolor y contacto piel con piel precoz en el parto vaginal o cesárea, lo que facilita que la madre inicie la lactancia más rápido. Si el escenario lo permite, se prefieren técnicas regionales, técnicas ahorradoras de opioides y cirugía ambulatoria, teniendo precaución con ciertos opioides y benzodiacepinas de acción larga especialmente ante dosis repetidas.

The Frailty Based on the Memorial Sloan Kettering Frailty Index for Prediction of Surgical Outcome in Advance Epithelial Ovarian Cancer-Experience of a Single Center in Mexico.

Retrospective impact evaluation of frailty as measured by the Memorial Sloan Kettering Frailty Index (MSK-FI) on outcomes in older women surgically treated for advanced epithelial ovarian cancer (EOC). Women ≥ 60 years with stage IIIC/IV EOC who underwent primary debulking surgery (PDS) or interval debulking surgery (IDS) were included. Medical records were reviewed for patients' characteristics and outcomes. We retrospectively applied the MSK-FI which included 10 comorbidities and functional assessment that were extracted from medical records. The MSK-FI ranges from 0 to 11; a score of ≥ 3 was considered frail. Associations were assessed using logistic regression and Cox proportional hazards regression. We identified 79 patients treated with PDS (n = 36, 45.5%) or IDS (n = 43, 54.4%) with complete data. The prevalence of frailty based on MSK-FI was 25%. Almost half of the frail patients (47.3%) were admitted to the ICU compared to 16% of non-frail patients (p = 0.006). In univariable analysis, the MSK-FI was associated with postoperative complications [OR 1.57 (95% CI 1.04-2.37), p = 0.03] and ICU admission [OR 2.05 (95% CI 1.30-3.23), p = 0.002], but not with readmission rate [OR 1.29 (95% CI 0.65-2.59), p = 0.5], postoperative mortality [OR 1.02 (95% CI 0.51-2.00), p = 0.9], and hospital stay [ß 0.60 (95% CI - 1.19-2.41)]. In multivariable analysis, the frailty index was independently associated with postoperative complications [OR 1.54 (95% CI 1.02-2.34), p = 0.04] and ICU admissions [OR 1.97 (95% CI 1.23-3.16), p = 0.004]. Frailty, based on the Memorial Sloan Kettering Frailty Index, is associated with adverse postoperative outcomes in older women with advanced ovarian cancer, suggesting that MSK-FI can improve the predictive ability of current surgical assessment tools.

The inductor role of cardiac consultation in the pre-anesthetic evaluation of asymptomatic patients submitted to non-cardiac minor and intermediate-risk surgery: a cross-sectional study.

INTRODUCTION: Asymptomatic patients with moderate functional capacity do not require Coronary Artery Disease (CAD) workup in the preoperative period of non-cardiac surgeries, especially when scheduled for minor and intermediate-risk surgeries. The workup is inappropriate because it promotes over diagnosing and pointless treatments. Moreover, those patients usually undergo cardiology assessment, in addition to pre-anesthetic evaluation. OBJECTIVE: Investigate the role of cardiology consultation as mediator in inappropriate assessment of CAD for preoperative of non-cardiac surgeries. METHOD: Retrospective study performed in a private anesthesia service using medical charts of asymptomatic patients with a history of controlled systemic disease and moderate functional capacity, submitted to pre-anesthetic consultation for minor and intermediate risk surgeries. Cardiology consultations were identified by the presence of a consultation report by a cardiologist. CAD workup was defined as undergoing cardiac stress tests. RESULTS: We included 390 medical charts of patients with mean age of 48.6 ± 15.4 years, 67% women and 69% intermediate risk surgeries. CAD workup was infrequent and performed in 3.9% of patients. Besides, pre-anesthetic evaluation, 93 (24%) patients had a cardiology consultation. Among those patients, 15.1% were submitted to CAD workup, compared to 0.34% of patients without cardiology assessment (p < 0.001; RR = 4.4; 95% CI: 3.5-5.6). CONCLUSIONS: Inappropriate testing for CAD investigation is infrequent for asymptomatic individuals submitted to minor and intermediate risk surgeries. However, cardiology consultation increases substantially the likelihood of a patient undergoing CAD workup, suggesting that, unlike the anesthesiologist, the cardiologist is a major mediator of this kind of management.

Preoperative patient education: can we improve satisfaction and reduce anxiety? / Informação pré-operatória ao paciente: podemos melhorar a satisfação e reduzir a ansiedade? / Información preoperatoria al paciente: ¿podemos mejorar la satisfacción y reducir la ansiedad?

BACKGROUND AND OBJECTIVES: Patients' knowledge deficits concerning anesthesia and the anesthesiologist's role in their care may contribute to anxiety. The objective of this study was to develop anesthesia patient education materials that would help improve patient's satisfaction regarding their knowledge of the perioperative process and decrease anxiety in a community hospital with a large Spanish-speaking population. METHODS: A survey (Survey A) in English and Spanish was administered to all adult anesthesiology preoperative clinic patients during a 4-week period. The data were analyzed and then a patient education handout was developed in both English and Spanish to assist with our patients' major concerns. A second survey (Survey B) was administered that was completed after the education handout had been put into use at the clinic. The survey asked for basic demographic information and included questions on satisfaction with regard to understanding of anesthesia as well as worries regarding surgery and pain. RESULTS: In the patients who received the handout, statistically significant improvement was found in the questions that asked about satisfaction with regard to understanding of type of anesthesia, options for pain control, what patients are supposed to do on the day of surgery, and the amount of information given with regard to anesthetic plan. There was no difference in anxiety related to surgery in patients who received the educational handout compared to those patients who did not. CONCLUSIONS: Patient education handouts improved patient's satisfaction regarding their knowledge of the perioperative process but did not reduce anxiety related to surgery. .

JUSTIFICATIVA E OBJETIVOS: A falta de conhecimento dos pacientes em relação à anestesia e ao papel do anestesiologista em sua assistência pode contribuir para a ansiedade. O objetivo deste estudo foi desenvolver materiais explicativos para o paciente sobre a anestesia que poderiam ajudar a melhorar a satisfação do paciente em relação ao seu conhecimento do processo perioperatório e a diminuir a ansiedade em hospital comunitário com uma grande população de língua espanhola. MÉTODOS: Durante quatro semanas, uma pesquisa (Pesquisa A) em inglês e espanhol foi feita no período pré-operatório com todos os pacientes adultos que seriam submetidos à anestesia. Os dados foram analisados e, posteriormente, um folheto explicativo foi desenvolvido em inglês e espanhol para esclarecer as principais preocupações dos pacientes. Uma segunda pesquisa (Pesquisa B) foi feita após a colocação do folheto explicativo em uso na clínica. A pesquisa investigou as informações demográficas básicas e incluiu perguntas sobre a satisfação relacionada à compreensão da anestesia, bem como as preocupações com a cirurgia e a dor. RESULTADOS: Nos pacientes que receberam o folheto houve melhoria estatisticamente significativa em relação às perguntas sobre a satisfação com a compreensão do tipo de anestesia, as opções para o controle da dor, o que os pacientes deveriam fazer no dia da cirurgia, bem como a quantidade de informações prestadas sobre o plano anestésico. Não houve diferença na ansiedade relacionada à cirurgia entre os pacientes que receberam e os que não receberam o folheto educativo. CONCLUSÕES: Os folhetos explicativos melhoraram a satisfação do paciente em relação ao conhecimento do processo perioperatório, mas não reduziram a ansiedade relacionada à cirurgia. .

Apnea del sueño como factor de riesgo en intervenciones quirúrgicas

La prevalencia de síndrome de apnea - hipopnea de sueño (SAHS) en la población general oscila entre 2 al 6% según el grupo etario y género. Pocos pacientes tienen diagnóstico confirmado y muchos menos se encuentran en tratamiento. En el transcurso de la vida deberán ser sometidos a distintos tipos de cirugías. El aumento del riesgo quirúrgico ha sido demostrado en varios estudios. Un meta-análisis confirmó el aumento de complicaciones (desaturación posoperatoria, insuficiencia respiratoria aguda, eventos cardíacos y la necesidad de traslado a UTI) en esta población. Se destaca además el auge de la cirugía bariátrica para tratar pacientes obesos mórbidos, que además tienen una alta incidencia de SAHS. Se revisan los múltiples mecanismos fisiopatológicos implicados tanto en el pre y postoperatorio, la influencia del tipo de cirugía, los efectos de medicamentos sedantes, anestésicos y analgésicos sobre la función respiratoria. Se recomienda una correcta evaluación preoperatoria. Cuestionarios validados, Berlín, STOP-BANG, P-SAP pueden ayudar en esta tarea, junto con el criterio clínico. El posoperatorio es el momento más crítico y que requiere mayores controles. Parece racional y prudente el uso de los equipos de CPAP para los pacientes que previamente los utilizan en su hogar. No está totalmente validada esta recomendación para los enfermos que no estén adaptados. Su uso podría disminuir las complicaciones relacionadas.(AU)

The prevalence of obstructive sleep apnea (SAHS) in the general population ranges from 2 to 6% by age group and gender. Few patients with confirmed diagnosis and fewer are treated. In the course of life must be subjected to different types of surgeries. The increased surgical risk has been demonstrated in several studies. A meta-analysis confirmed the increased complications (postoperative desaturation, acute respiratory failure, cardiac events and the need for transfer to ICU) in this population. The rise of bariatric surgery for morbidly obese patients, who also have a high incidence of SAHS is further underlined. Multiple pathophysiological mechanisms involved before and after surgery, the influence of the type of surgery, the effects of sedative drugs, anesthetics and analgesics on respiratory function are reviewed. Proper preoperative evaluation is recommended. Validated questionnaires, Berlin, STOP-BANG, P-SAP can help in this task, along with clinical judgment. Postoperative time is the most critical and requires greater controls. It seems prudent and rational use of CPAP equipment for patients who previously used in the home. Not fully validated this recommendation for patients who are not suitable. Its use could reduce related complications.(AU)

Manejo preoperatorio de medicamentos en pacientes hipertensos / Preoperative pharmacological management of hypertensive patients

The proportion of older hypertensive patients that require a surgical procedure has increased in the last years. These patients require a through preoperative assessment, considering the medications in use, laboratory and images. An adequate pharmacological management of patients with hypertension in the perioperative period will prevent cardiovascular complications. Therefore the health care team must assure that patients with hypertension will be operated in optimal conditions.

La hipertensión arterial es una enfermedad con alta prevalencia en la población chilena, llegando a casi el 75 por ciento en el grupo de mayores de 65 años. En el ámbito quirúrgico, el número de pacientes de edad mayor y que padecen hipertensión arterial ha aumentado significativamente, lo que nos obliga a realizar una adecuada y detallada evaluación preoperatoria del paciente hipertenso con el fin de conocer su condición al momento de la cirugía, los medicamentos antihipertensivos que utiliza y solicitar los exámenes de laboratorio y/o de imágenes necesarios. Una adecuada asesoría al paciente respecto al manejo de su medicación antihipertensiva preoperatoria pretende disminuir las complicaciones en todo el período perioperatorio, tanto por su suspensión como por su mantención. De esta forma se busca establecer las medidas que permitan al paciente enfrentar el procedimiento quirúrgico en las mejores condiciones posibles.

Control glucémico en el proceso perioperatorio de los pacientes con diabetes mellitus / Glycemia control in the perioperative process of patients presenting with diabetes mellitus

El paciente diabético requiere con frecuencia algún tipo de cirugía o la realización de un proceder diagnóstico invasivo, que puede, incluso, ser realizado de urgencia. En la actualidad el riesgo quirúrgico del diabético ha disminuido gracias a los avances en las técnicas anestésicas y al control metabólico perioperatorio, aunque las complicaciones aún son más frecuentes, y generan una hospitalización prolongada y una tasa mayor de invalidez. En la evaluación preoperatoria se deben precisar las características de la diabetes, el tipo de proceder quirúrgico, el riesgo anestésico quirúrgico, y realizar los ajustes necesarios al tratamiento habitual. La infusión continua de insulina endovenosa con aporte de glucosa es el método más racional y fisiológico en la mayoría de las intervenciones quirúrgicas, lo que implica monitoreo glucémico frecuente con ajustes inmediatos. Algunas situaciones especiales, como las cirugías complejas o las de urgencia, requieren esquemas terapéuticos específicos, por lo que cada equipo debe tener su protocolo de trabajo, según las particularidades de las intervenciones quirúrgicas que realicen. El control metabólico perioperatorio es esencial para evitar las alteraciones metabólicas e hidroelectrolíticas agudas y favorecer la evolución satisfactoria en el posoperatorio. Por su importancia, se realiza una revisión con un enfoque actual, que ayude a mejorar la calidad de la atención al paciente diabético que requiere de una intervención quirúrgica(AU)

The diabetic patients require frequently some type of surgery or the implementation of an invasive diagnostic procedure which may even be carried out as an emergence. Nowadays the surgical risk of the diabetic patient has decrease thanks to the advances in the anesthetic techniques and to the perioperative metabolic control, although the complications are more frequent and to generate a lengthy hospitalization and a great disability rate. In the preoperative assessment it is necessary to specify exactly the diabetes's features, the type of surgical procedure, surgical anesthetic risk and to perform the fitting necessary in the habitual treatment. The continuous infusion of intravenous insulin with glucose is the more rational and physiologic method in most of surgical interventions, involving the frequent glycemia monitoring with immediate fittings. Some special situations including complicated surgeries or those of emergence, require specific therapeutical schemes, thus each staff must to have its work protocol, according the peculiarities of the surgical interventions performed. The perioperative metabolic control is essential to avoid the metabolic and acute hydroelectrolytic alterations and to favor the satisfactory course during the postoperative period. Due its significance, authors carried out a review with the current approach helping to improve the quality of care of diabetic patient requiring a surgical intervention(AU)

Aspectos gerais da avaliação pré-operatória do paciente idoso cirúrgico / General features of the preoperative assessment of surgical elderly patient

As intervenções cirúrgicas em pacientes idosos têm se tornado cada vez mais frequentes, uma vez que esta população vem apresentando crescimento em número significativo nas últimas décadas e consequentemente expondo-se por mais tempo às morbidades de resolução cirúrgica. Apesar de um número importante de idosos apresentarem envelhecimento saudável e tolerarem o ato cirúrgico sem muitas intercorrências, sabe-se também que a morbi-motalidade que envolve a operação é mais frequente no indivíduo idoso e requer muito mais cuidado naquele com comorbidades. O presente trabalho se propõe a rever alguns aspectos que merecem ser mais cuidadosamente observados, porque envolvem modificações morfológicas e funcionais do organismo senescente, que guardam relação com o aumento da morbidade e da mortalidade em todo o período peri-operatório. A avaliação pré-operatória, portanto, deve pautar-se em exame criterioso de toda história clínica do paciente com vistas a estabelecer medidas de prevenção de eventos mórbidos, evitar iatrogenias, estabelecer critérios que alertem para um maior risco e desenvolver enfoque multidisciplinar.

The surgical interventions in elderly patients have become more frequent once this population have presented expressive increase in last decades, resulting a longer exposure to surgical resolution morbidities. Despite a large number of elder people presents a healthy aging and support the surgical act well, the morbidity and mortality that involves the surgery is more often in elderly and request more care to ones with comorbidities. The present work purpose to review some aspects that must be more carefully observed because involves morphological and functional changes from senescent organism that bring into relation with the increase of morbidity and mortality in preoperative period. Thus, the preoperative evaluation must be based on carefully clinical examination in order to prevent morbid events, iatrogenic ones, to set up risk criteria and to development a multidisciplinary focus.

A influência de sintomas de depressão na frequência de complicações pós-operatórias precoces de pacientes submetidos a cirurgia torácica / The influence of symptoms of depression on the early postoperative complications of thoracic surgical patients

Introdução: É sabido que a depressão exerce papel deletério no pós-operatório de cirurgias ortopédicas e cardiovasculares. Objetivo: Avaliar a influência de sintomas depressivos sobre a ocorrência de complicações no período pós-operatório precoce de pacientes submetidos a cirurgia torácica não cardíaca. Metodologia: Como desenho foi definido uma série de casos prospectiva. Cenário: hospital universitário terciário. Sujeitos: quarenta e oito pacientes (idade média: 62±9 anos; 29 homens) tratados com toracotomia e ressecção de parênquima pulmonar pneumonectomia (16,6 por cento); lobectomia ou ressecção menor (83,4 por cento). Métodos: candidatos consecutivos a cirurgia torácica não cardíaca a céu aberto tiveram seus níveis de depressão avaliados na semana anterior ao procedimento cirúrgico utilizando-se o Inventário Beck de Depressão (BDI). As equipes cirúrgica e clínica e o paciente eram cegos para o resultado de BDI. As seguintes variáveis foram coletadas e registradas após a realização do procedimento cirúrgico: 1) tempo de permanência em unidade de tratamento intensivo (UTI) superior a três dias; 2) necessidade de ventilação mecânica secundária a insuficiência respiratória; 3) pneumonia; e 4) necessidade de reintervenção cirúrgica. Resultados: houve diferença significativa de 10,2 pontos (IC95 por cento: 20,37 a 0,02) nos índices pré-operatórios de BDI entre pacientes que desenvolveram ou não desenvolveram pneumonia no pós-operatório, 21,0±9,5 e 10,8±8,2, respectivamente (p=0,04). Conclusões: estado depressivo pode afetar negativamente o pós-operatório precoce de pacientes submetidos a cirurgia torácica não cardíaca, levando a um aumento na taxa de pneumonias.

Introduction: It is known that depression plays a deleterious role in the postoperative recovery of patients submitted to orthopedic and cardiovascular surgeries. Aim: To evaluate the influence of depression symptoms on the occurrence of postoperative complications in patients submitted to non-cardiac thoracic surgeries. Methods: The design was a prospective case series. Setting: Tertiary school hospital. Subjects: 48 patients (mean age 62±9 years; 29 males) submitted to thoracotomy and resection of the pulmonary parenchyma pneumonectomy (16.6 percent); lobectomy or smaller resection (83,4 percent). Methods: Consecutive candidates to non-cardiac open thoracic surgery had their levels of depression evaluated one week before the surgical procedure using the Beck Depression Inventory (BDI). The clinical and surgical teams and the patient were blind to the BID result. The following variables were collected and recorded after the performance of the surgical procedure: 1) time of stay in the intensive care unit (ICU) above 3 days; 2) need for mechanical ventilation secondary to respiratory failure; 3) pneumonia; and 4) need for surgical reintervention. Results: There was a significant difference of 10.2 points (CI95 percent: 20.37 to 0.02) in the BDI preoperative indexes among the patients who developed or did not develop pneumonia in the post-operative period (21.0±9.5 and 10.8±8.2, respectively) (p=0.04). Conclusions: A depressive state may adversely affect the early postoperative recovery of patients submitted to non-cardiac thoracic surgeries, leading to an increase in the rate of pneumonias.
