Rethinking the routine: Preoperative laboratory testing among American Society of Anesthesiologists class 1 and 2 patients before low-risk ambulatory surgery in the 2017 National Surgical Quality Improvement Program cohort.

BACKGROUND: Routine preoperative laboratory testing is not recommended for American Society of Anesthesiologists classification 1 or 2 patients before low-risk ambulatory surgery. METHODS: The 2017 National Surgical Quality Improvement Program data set was retrospectively queried for American Society of Anesthesiologists class 1 and 2 patients who underwent low-risk, elective outpatient anorectal, breast, endocrine, gynecologic, hernia, otolaryngology, oral-maxillofacial, orthopedic, plastic/reconstructive, urologic, and vascular operations. Preoperative laboratory testing was defined as any chemistry, hematology, coagulation, or liver function studies obtained ≤30 days preoperatively. Demographics, comorbidities, and outcomes were compared between those with and without testing. The numbers needed to test to prevent serious morbidity or any complication were calculated. Laboratory testing costs were estimated using Centers for Medicare and Medicaid Services data. RESULTS: Of 111,589 patients studied, 57,590 (51.6%) received preoperative laboratory testing; 26,709 (46.4%) had at least 1 abnormal result. Factors associated with receiving preoperative laboratory testing included increasing age, female sex, non-White race/ethnicity, American Society of Anesthesiologists class 2, diabetes, dyspnea, hypertension, obesity, and steroid use. Mortality did not differ between patients with and without testing. The complication rate was 2.5% among tested patients and 1.7% among patients without tests (P < .01). The numbers needed to test was 599 for serious morbidity and 133 for any complication. An estimated $373 million annually is spent on preoperative laboratory testing in this population. CONCLUSION: Despite American Society of Anesthesiologists guidelines, a majority of American Society of Anesthesiologists class 1 and 2 patients undergo preoperative laboratory testing before elective low-risk outpatient surgery. The differences in the rates of complications between patients with and without testing is low. Preoperative testing should be used more judiciously in this population, which may lead to cost savings.

Experience of clinical screening for COVID-19 among patients undergoing elective orthopedic surgeries: an alternative proposal.

BACKGROUND: The coronavirus disease 2019 (COVID-19) pandemic is the largest global event in recent times, with millions of infected people and hundreds of thousands of deaths worldwide. Colombia has also been affected by the pandemic, including by the cancellation of medically necessary surgical procedures that were categorized as nonessential. The objective of this study was to show the results of the program implemented in two institutions in Bogotá, Colombia, in April 2020 to support the performance of elective essential and nonessential low- and medium-complexity orthopedic surgeries during the mitigation phase of the COVID-19 pandemic, which involved a presurgical clinical protocol without serological or molecular testing. METHODS: This was a multicenter, observational, retrospective, descriptive study of a cohort of patients who underwent elective orthopedic surgery at two institutions in the city of Bogota, Colombia, in April 2020. We implemented a preoperative clinical protocol that did not involve serological or molecular tests; the protocol consisted of a physical examination, a survey of symptoms and contact with confirmed or suspected cases, and presurgical isolation. We recorded the types of surgeries, the patients' scores on the medically necessary, time-sensitive (MeNTs) scale, the presence of signs, symptoms, and mortality associated with COVID-19 developed after the operation. RESULTS: A total of 179 patients underwent orthopedic surgery. The average age was 47 years (Shapiro-Wilk, P = 0.021), and the range was between 18 and 81 years. There was a female predominance (61.5%). With regard to the types of surgeries, 86 (48%) were knee operations, 42 (23.5%) were hand surgeries, 34 (19%) were shoulder surgeries, and 17 (9.5%) were foot and ankle surgeries. The average MeNTs score was 44.6 points. During the 2 weeks after surgery, four patients were suspected of having COVID-19 because they developed at least two symptoms associated with the disease. The incidence of COVID-19 in the postoperative period was 2.3%. Two (1.1%) of these four patients visited an emergency department where RT-PCR tests were performed, and they tested negative for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). No patients died or were hospitalized for symptoms of COVID-19. CONCLUSION: Through the implementation of a presurgical clinical protocol consisting of a physical examination; a clinical survey inquiring about signs, symptoms, and epidemiological contact with suspected or confirmed cases; and presurgical isolation but not involving the performance of molecular or serological diagnostic tests, positive results were obtained with regard to the performance of low- and medium-complexity elective orthopedic surgeries in an early stage of the COVID-19 pandemic. LEVEL OF EVIDENCE: IV.

Is Preoperative Preparation Time a Barrier to Small Children Being Ready for Kidney Transplantation?

BACKGROUND: Small children are less frequently transplanted when compared with older. The objective of the present study was to compare the preparation time for transplantation in children of different weights and to identify factors associated with a delay in the workup of small children. METHODS: We report on a retrospective cohort comprising all children referred for renal transplantation (RTx) workup between 2009 and 2017. The main outcome was transplantation workup time, defined as the time elapsed between the first consultation and when the child became ready for the surgery. RESULTS: A total of 389 children (63.5% males) were selected, with a median weight of 18 kg (interquartile range, 11-32). Patients were categorized into 2 groups: group A (study group): ≤15 kg (n = 165) and group B (control group): >15 kg (n = 224). The probability of being ready for RTx was comparable between groups A and B. The cumulative incidence rate difference between groups is -0.05 (95% confidence interval, -0.03 to 0.02). The median time for RTx workup was 5.4 (2.4-9.4) in group A and 4.3 (2.2-9.0) months in group B (P = 0.451). Moreover, the presence of urinary tract malformation was associated with the need for longer transplantation workup time (P < 0.001). CONCLUSIONS: In children >7 kg, the workup time for transplantation is not related to body weight. In a specialized center, children weighing 7-15 kg became ready within the same timeframe as children weighing >15 kg, despite the smaller children had greater difficulty being nourished, dialyzed, and a greater need for surgical correction of the urinary tract pretransplant.

Clinical practice guidelines for surgical antimicrobial prophylaxis: Qualitative appraisals and synthesis of recommendations.

RATIONALE, GOALS, AND OBJECTIVES: Clinical practice guidelines (CPGs) for preoperative care have been developed for surgical antimicrobial prophylaxis (SAP). The objective of this study was to synthetize recommendations for SAP based on best-evaluated CPGs. METHODS: A systematic literature search for documents related to SAP, published between January 2011 and December 2016, was conducted on MEDLINE (PubMed), EMBASE, and specific CPG websites. Three reviewers independently assessed the rigour of development and editorial independence of CPGs based on domains 3 and 6 of the Appraisal of Guidelines for Research & Evaluation II (AGREE II) instrument. CPGs with domain 3 scores of 50% and greater were selected for synthesis of recommendations. Two reviewers independently extracted CPG recommendations from among these documents. A third reviewer performed the synthesis of recommendations. RESULTS: The search retrieved 363 documents, of which 29 CPGs were appraised using AGREE II. Only eight (28%) scored 50% and greater in domain 3. Most CPGs addressed topics related to preoperative care, including SAP. No conflicting recommendations were found, and most recommendations were based on clinical practice. The only recommendation for which there was a difference among CPGs was with respect to the time to initiate the administration of antibiotics (1 hour before or close to the time of the surgical incision). Four CPGs provide recommendations that demonstrate concern about inadequate SAP prolongation. CONCLUSION: Several CPGs for SAP were developed without the desired methodological rigour or transparency. Synthesis of recommendations for best-evaluated CPGs provides a broad approach owing to the complementarity of the recommendations.

Being-patient-waiting-for-cardiac-surgery: the preoperative period under the Heideggerian perspective.

OBJECTIVE: to investigate the patients' experience in the cardiac surgery preoperative period under the Heideggerian perspective. METHOD: exploratory qualitative research. Twelve patients were interviewed, from March to April, 2016, while they waited for myocardial revascularization surgery or valve replacement surgery. RESULTS: the analysis of the speeches allowed finding two dimensions of the being-there-patient-waiting-for-cardiac surgery, two meanings of the beingness: being-there-in-a-reduced-world and being-there-in-a-unknown-world. CONCLUSION: the experiences were related to alterations and limitations coming from the surgery, potential generators of anxiety, depression and existential conflicts in the cardiac surgery preoperative period. Reinforcing the care as being-with-the-other is suggested, considering the dimensions referred to and the patient's integrality.

PRE-OPERATIVE FASTING: WHY ABBREVIATE?

INTRODUCTION: Considering the practice of preoperative fasting based on observations on the gastric emptying delay after induction and the time of this fast is closely linked to organic response to trauma, arise the question about preoperative fasting period necessary to minimize such response and support the professional with clinical and scientific evidence. AIM: To review the aspects related to the abbreviation of preoperative fasting from the metabolic point of view, physiology of gastric emptying, its clinical benefits and the currently recommendations. METHOD: Literature review was based on articles and guidelines published in English and Portuguese, without restriction of time until January 2017, in PubMed, SciELO and Cochrane with the descriptors: surgery, preoperative fasting, carbohydrate. From the universe consulted, 31 articles were selected. RESULTS: The literature suggests that the abbreviation of fasting with beverage added carbohydrates until 2 h before surgery, can bring benefits on glycemic and functional parameters, reduces hospitalization, and does not present aspiration risk of healthy patients undergoing elective surgery. Another nutrient that has been added to the carbohydrate solution and has shown promising results is glutamine. CONCLUSION: The abbreviation of preoperative fasting with enriched beverage with carbohydrates or carbohydrate and glutamine seems to be effective in the care of the surgical patient, optimizing the recovery from of postoperative period.

Preoperative ANemiA among the elderly undergoing major abdominal surgery (PANAMA) study: Protocol for a single-center observational cohort study of preoperative anemia management and the impact on healthcare outcomes.

INTRODUCTION: Preoperative anemia and old age are independent risk factors for perioperative morbidity and mortality. However, despite the high prevalence of anemia in elderly surgical patients, there is limited understanding of the impact of anemia on postoperative complications and postdischarge quality of life in the elderly. This study aims to investigate how anemia impacts elderly patients undergoing major abdominal surgery in terms of perioperative morbidity, mortality and quality of life for 6 months postoperatively. METHODS AND ANALYSIS: We will conduct a prospective observational study over 12 months of 382 consecutive patients above 65 years old, who are undergoing elective major abdominal surgery in Singapore General Hospital (SGH), a tertiary public hospital. Baseline clinical assessment including full blood count and iron studies will be done within 1 month before surgery. Our primary outcome is presence of morbidity at fifth postoperative day (POD) as defined by the postoperative morbidity survey (POMS). Secondary outcomes will include 30-day trend of POMS complications, morbidity defined by Clavien Dindo Classification system (CDC) and Comprehensive Complication Index (CCI), 6-month mortality, blood transfusion requirements, days alive out of hospital (DaOH), length of index hospital stay, 6-month readmission rates and Health Related Quality of Life (HRQoL). HRQoL will be assessed using EuroQol five-dimensional instrument (EQ-5D) scores at preoperative consult and at 1, 3, and 6 months. ETHICS AND DISSEMINATION: The SingHealth Centralised Institutional Review Board (CIRB Ref: 2017/2640) approved this study and consent will be obtained from all participants. This study is funded by the National Medical Research Council, Singapore (HNIG16Dec003) and the findings will be published in peer-reviewed journals and presented at academic conferences. Deidentified data will be made available from Dryad Repository upon publication of the results.

Comparative Effectiveness and Risks of Bowel Preparation Before Elective Colorectal Surgery.

OBJECTIVE: The objective of this study was to determine the relationship between bowel preparation and surgical site infections (SSIs), and also other postoperative complications, after elective colorectal surgery. BACKGROUND: SSI is a major source of postoperative morbidity/costs after colorectal surgery. The value of preoperative bowel preparation to prevent SSI remains controversial. METHODS: We analyzed 32,359 patients who underwent elective colorectal resections in the American College of Surgeons National Surgery Quality Improvement Program database from 2012 to 2014. Univariable and multivariable analyses were performed; propensity adjustment using patient/procedure characteristics was used to account for nonrandom receipt of bowel preparation. RESULTS: 26.7%, 36.6%, 3.8%, and 32.9% of patients received no bowel preparation, mechanical bowel preparation (MBP), oral antibiotics (OA), and MBP + OA, respectively. After propensity adjustment, MBP was not associated with decreased risk of SSI compared with no bowel preparation. In contrast, both OA and OA + MBP were associated with decreased risk of any SSI (adjusted odds ratio 0.49, 95% confidence interval 0.38-0.64; and adjusted odds ratio 0.45, 95% confidence interval 0.40-0.50, respectively) compared with no bowel preparation. OA and MBP + OA were associated with decreased risks of anastomotic leak, postoperative ileus, readmission, and also shorter length of stay (all P < 0.05). Bowel preparation was not associated with increased risk of cardiac/renal complications compared with no preparation. CONCLUSIONS: The use of MBP alone before elective colorectal resection to prevent SSI is ineffective and should be abandoned. In contrast, OA and MBP + OA are associated with decreased risks of SSI and are not associated with increased risks of other adverse outcomes compared with no preparation. Prospective studies to determine the efficacy of OA are warranted; in the interim, MBP + OA should be used routinely before elective colorectal resection to prevent SSI.

RESUMO Introdução : Considerando que a prática do jejum pré-operatório é baseada nas observações do retardo do esvaziamento gástrico após a indução anestésica e que o tempo deste jejum está intimamente ligado à resposta orgânica ao trauma, surge o questionamento acerca do período de jejum necessário para minimizar tal resposta e respaldar a atuação profissional em evidências clinicocientíficas. Objetivo : Revisar a abreviação do jejum pré-operatório, sob o ponto de vista metabólico, da fisiologia do esvaziamento gástrico, seus benefícios clínicos e recomendações atualmente vigentes. Método : A revisão foi baseada em artigos e guidelines publicados em inglês e português, sem restrição de tempo até janeiro de 2017, no PubMed, SciELO e Cochrane com os descritores: cirurgia, jejum pré-operatório, carboidrato. Do universo consultado 31 artigos foram selecionados. Resultados : A literatura aponta que a abreviação do jejum com bebida enriquecida com carboidratos até 2 h antes do procedimento cirúrgico pode trazer benefícios sobre parâmetros glicêmicos, funcionais, redução da hospitalização, além de não oferecer risco de broncoaspiração em indivíduos saudáveis submetidos à operações eletivas. Outro nutriente frequentemente adicionado a esta solução de carboidratos, com resultados promissores, é a glutamina. Conclusão : A abreviação do jejum pré-operatório com bebida enriquecida com carboidratos ou carboidratos e glutamina parece mostrar-se eficaz no cuidado ao paciente cirúrgico otimizando a recuperação do período pós-operatório.

Safe surgery: validation of pre and postoperative checklists.

Objective: to develop, evaluate and validate a surgical safety checklist for patients in the pre and postoperative periods in surgical hospitalization units. Method: methodological research carried out in a large public teaching hospital in the South of Brazil, with application of the principles of the Safe Surgery Saves Lives Programme of the World Health Organization. The checklist was applied to 16 nurses of 8 surgical units and submitted for validation by a group of eight experts using the Delphi method online. Results: the instrument was validated and it was achieved a mean score ≥1, level of agreement ≥75% and Cronbach's alpha >0.90. The final version included 97 safety indicators organized into six categories: identification, preoperative, immediate postoperative, immediate postoperative, other surgical complications, and hospital discharge. Conclusion: the Surgical Safety Checklist in the Pre and Postoperative periods is another strategy to promote patient safety, as it allows the monitoring of predictive signs and symptoms of surgical complications and the early detection of adverse events.

CHANGING PARADIGMS IN PREOPERATIVE FASTING: RESULTS OF A JOINT EFFORT IN PEDIATRIC SURGERY.

BACKGROUND:: Current researches associate long fasting periods to several adverse consequences. The fasting abbreviation to 2 h to clear liquids associated with the use of drinks containing carbohydrates attenuates endocrinometabolic response to surgical trauma, but often is observed children advised to not intake food from 00:00 h till the scheduled surgical time, regardless of what it is. AIM:: To evaluate the safety of a protocol of preoperative fasting abbreviation with a beverage containing carbohydrates, and early postoperative feeding in children underwent elective small/mid-size surgical procedures during a national task-force on pediatric surgery. METHODS:: Thirty-six patients were prospectively included, and for several reasons five were excluded. All 31 who remained in the study received a nutritional supplement containing 150 ml of water plus 12.5% maltodextrin 2 h before the procedure. Data of the pre-operative fasting time, anesthetic complications and time of postoperative refeeding, were collected. RESULTS:: Twenty-three (74.2%) were males, the median age was 5 y, and the median weight was 20 kg. The median time of pre-operative fasting was 145 min and the time of post-operative refeeding was 135 min. There were no adverse effects on the anesthetic procedures or during surgery. Post-operatively, two children (6.5%) vomited. CONCLUSION:: The abbreviation of pre-operative fasting to 2 h with beverage containing carbohydrate in pediatric surgery is safe. Early refeeding in elective small/mid-size procedures can be prescribed. RACIONAL:: Trabalhos atuais associam longos períodos de jejum com diversas consequências adversas. A abreviação do jejum de 2 h para líquidos claros associado ao uso de bebidas contendo carboidratos atenua resposta endocrinometabólica ao trauma, porém frequentemente as crianças são orientadas a não ingerir alimentos a partir das 00:00 h do dia anterior à operação, independente do horário do procedimento cirúrgico. OBJETIVO:: Avaliar a segurança de um protocolo de abreviação do jejum pré-operatório, com o uso de bebida contendo carboidratos, e realimentação precoce. MÉTODOS:: Foram avaliados prospectivamente 36 crianças submetidas a procedimentos cirúrgicos eletivos de pequeno e médio porte. Cinco foram posteriormente excluídos do estudo. Todos os 31 remanescentes receberam suplemento nutricional com maltodextrina 12,5% em 150 ml de água aproximadamente 2 h antes do procedimento. Foram coletados dados do tempo de jejum pré-operatório, complicações anestésicas e tempo de realimentação. RESULTADOS:: Vinte e três (74,2%) eram do gênero masculino, com idade mediana de cinco anos e peso mediano de 20 kg. O tempo mediano de jejum pré-operatório foi de 145 min e o tempo mediano para realimentação foi de 135 min. Não houve eventos adversos durante a anestesia ou operação. No período pós-operatório, duas (6,5%) crianças vomitaram. CONCLUSÃO:: A abreviação de jejum pré-operatório para 2 h com uso de bebida contendo carboidratos, em operações eletivas de crianças, é seguro e não está associado ao maior risco de broncoaspiração pulmonar. Realimentação precoce pode ser prescrita nos procedimentos cirúrgicos analisados.

A avaliação pré-anestésica para cirurgia oftalmológica em idosos é realmente necessária? A realidade de um hospital público / The pre-anesthetic evaluation for ophthalmic surgery in the elderly is really necessary? The reality of a public hospital

RESUMO Objetivos: A avaliação pré-anestésica (APA) e a realização de exames laboratoriais são questionadas para cirurgias oftalmológicas ambulatoriais por acrescentarem custos e retardarem a cirurgia. Estas são de baixo risco, mas os pacientes são idosos e com várias comorbidades. O objetivo deste estudo foi determinar se a APA é realmente necessária nestes pacientes em um hospital público. Métodos: Foi conduzido um estudo retrospectivo em 297 prontuários contendo a APA de pacientes para cirurgias oftalmológicas em um hospital público. Foram avaliados através da história, exame clínico e exames complementares, a proporção de pacientes que apresentaram na APA doenças desconhecidas ou não controladas e alterações dos exames complementares. Resultados: A média de idade dos pacientes foi de 71,5 anos, com 95,28% tendo pelo menos uma doença crônica. A doença mais prevalente foi hipertensão arterial sistêmica (62,96%), que em 7,7% dos pacientes estavam sem controle adequado; 2.3% não tinham diagnóstico de HAS. O diabetes mellitus tipo 2 apareceu em segundo (22,22%), com 5,3% sem controle adequado. Glicemia acima de 100 mg.dl-1 foi encontrada em 25,92%, sem diagnóstico conhecido. Do total, 84,8% tomavam pelo menos um medicamento. Somente 73,4% dos pacientes foram liberados para a cirurgia na primeira consulta. Conclusão: A APA em oftalmologia é capaz de detectar doenças não diagnosticadas, ou condições clínicas instáveis, e exerce um papel não só de otimização do paciente para a cirurgia como de atendimento primário, desempenhando papel importante na saúde global da população e, portanto, considerada necessária nos pacientes idosos do sistema público de saúde.

ABSTRACT Objectives: Pre-anesthetic assessment (PAA) and laboratory tests are questioned for ophthalmic procedures due to their additional costs and surgery delays. These are lower risks, nonetheless, patients are elderly and suffer from multiple comorbidities. The aim of this study was to determinate if it is really necessary in a public hospital. Method: a retrospective study on 297 medical records containing the pre-anesthetic questionary from ophthalmic surgery patients in a public hospital was leaded. By the anamnesis, clinical examination and laboratory tests, the rate of patients who came up with unknown or uncontrolled diseases for the pre-anesthetic evaluation among with unsettled lab tests were analyzed. Results: The patients's mean age was 71.5 years old. 95.28% of them suffer from at least one chronic disease. The most prevailer illness was systemic arterial hypertension (SAH) (62.96%), which in 7.7% of were uncontroled. Also 2.3% had no diagnosis of SAH. The DM2 appeared in second (22.22%), with 5.3% without proper management. Glycaemia above 100 mg.dl1 was found in 25.92%, undiagnosed; 84.8% of the total were taking at least one medication. Only 73.4% of patients were released for surgery in the first moment. Discussion: To sum up, PAA in ophthalmology surgery is able to bring up undiagnosed diseases, or unstable medical conditions, and it plays a role not only in optimize the patient for surgery, but also as primary care. It can be an important deal to improve population's health, therefore, considered necessary in elderly patients in the public health system.

The accuracy of different methods for diagnosing septal deviation in patients undergoing septorhinoplasty: A prospective study.

OBJECTIVE: This study aimed to determine the diagnostic accuracy of different diagnostic tests in predicting nasal septum deformities during preoperative planning for septorhinoplasty. METHODS: Consecutive patients who underwent septorhinoplasty between June 2011 and August 2012 were included (n = 30) and underwent a protocol of diagnostic tests, including nasal speculoscopy, craniofacial computed tomography (CT), three-dimensional (3D) reconstruction of the nasal septum by CT and nasal endoscopy. A modified Guyuron classification of septal deformities was used for classifying the septal deviations. Direct surgical assessment of the nasal septum during open septorhinoplasty was the reference standard with which each of the diagnostic tests was compared. Sensitivity, specificity and predictive values of each test were calculated. RESULTS: The preoperative diagnosis was nasal bone fracture in 11 patients, nasal septal fracture in 15 and post-traumatic nasal deformity in four. For type A deviations (localised), craniofacial CT showed the highest performance with a sensitivity of 100%, specificity of 100%, positive predictive value (PPV) of 100% and negative predictive value (NPV) of 99%. For type B septal deformations (C shape), nasal endoscopy (sensitivity, 100%; specificity, 87.5%; PPV, 87.7%; and NPV, 100%) showed the highest performance. For type C deformities (S shape), nasal endoscopy (sensitivity, 70%; specificity, 100%; PPV, 100%; and NPV, 87%) showed the highest performance. The accuracy for nasal endoscopy was 27/30 (90%), 26/30 (87%) for craniofacial CT, 22/30 (73%) for 3D reconstruction and 10/28 (36%) for speculoscopy. CONCLUSIONS: Nasal endoscopy and craniofacial CT were more accurate and precise than nasal speculoscopy and 3D reconstruction for preoperative evaluation of the nasal septum, thus enabling more appropriate surgical planning for septorhinoplasty.

Safe pediatric surgery: development and validation of preoperative interventions checklist.

OBJECTIVES: This study was aimed at developing and validating a checklist of preoperative pediatric interventions related to the safety of surgical patients. METHOD: Methodological study concerning the construction and validation of an instrument with safe preoperative care indicators. The checklist was subject to validation through the Delphi technique, establishing a consensus level of 80%. RESULTS: Five professional specialists in the area conducted the validation and a consensus on the content and the construct was reached after two applications of the Delphi technique. CONCLUSION: The "Safe Pediatric Surgery Checklist", simulating the preoperative trajectory of children, is an instrument capable of contributing to the preparation and promotion of safe surgery, as it identifies the presence or absence of measures required to promote patient safety.
