Este estudo objetivou avaliar o perfil clínico e epidemiológico de pacientes submetidos à cirurgia de prótese de quadril e que sofreram complicações relacionadas a esta no pós-operatório. A pesquisa foi realizada no período de 2002 a 2006; a amostra inicial foi composta de 398 cirurgias de pacientes submetidos à Artroplastia Primária de Quadril, realizadas em um hospital escola especializado da Cidade de São Paulo. Em 48 destas cirurgias ocorreram complicações pós-operatórias, compondo a amostra final deste estudo. Houve predominância de indivíduos do sexo feminino (66,7%), com média de idade de 59 anos, casados ou em união estável/amasiado (43,4%), provenientes da cidade de São Paulo (55,3%). Referente à escolaridade a maioria (58,1%) tinha fundamental completo. Quanto à ocupação houve predominância de aposentados e pacientes que desenvolvem atividades técnicas e ocupacionais, ambos com 35,1%. Infecção do quadril foi o motivo predominante para revisão da prótese de quadril (33,3%). A Vancomicina e a Ceftazidima, associadas, foram os antibióticos mais utilizados (58,1%). O estudo contribui para a estruturação de um cuidar multidisciplinar e especializado, pois possibilita o conhecimento da clientela, através de um perfil sociodemográfico e clínico, proporcionando mecanismos para intervenções de modo a transformar a assistência de Enfermagem em Ortopedia e Traumatologia e Reabilitação Física / This study was aimed at evaluating the clinical and epidemiological profile of patients submitted to hip prosthesis surgery who had complications related to it in the post-surgery period. The research was conducted between 2002 and 2006; the initial sample was comprised of 398 surgeries of patients submitted to Primary Hip Arthroplasty, performed at a specialized school hospital in the city of São Paulo. In 48 of those surgeries there were post-surgery complications, thus comprising the final sample of this study. There was a predominance of females (66.7%), with average age of 59, married or with a stable union (43.4%), living in the city of São Paulo (55.3%). Regarding education, most (58.1%) had finished primary school. As for occupation, the majority were retirees and patients that perform technical and occupational activities, both with 35.1%. Hip infection was the most common cause for hip prosthesis revision (33.3%). Vancomycin and ceftazydime, used together, were the most used antibiotics (58.1%). The study helps the development of a multidisciplinary, specialized care because it brings information about the clientele through a socio-demographic and clinical profile, thus providing mechanisms for interventions so as to transform care in Orthopedic and Traumatology Nursing and in Physical Rehabilitation Nursing

Post surgical adhesions (PSAs) are an inevitable outcome of surgery and their presence leads to pathogeneses and significant economic impact. The studies within this thesis utilised standard and reproducible abrasion models, in rabbits, pigs and rats, to investigate the formation and maturation of PSAs with strict quantitative analyses. These studies have shown that the development of PSAs is a series of complex, multi-factorial processes. PSA development can be classified into two stages: (i) PSA modelling occurring up to/including 16 hours post injury characterised by the inflammatory response and fibrin deposition and maturation; and (ii) PSA remodelling occurring from 16 hours onwards and characterised by tissue repair, collagen deposition and maturation and chemical mediation by TGF-P. Treatment with VivostatTM System Derived (novel) Fibrin Sealant significantly reduced the formation of PSAs with mean PSA reduction of 80% for the rabbit uterine horn abrasion model, from 3 separate studies; 83% for the pig stomach/colon/caecum abrasion model, from 2 separate studies; 80% for the rat caecum abrasion model. This is significantly better than other fibrin sealants investigated in this thesis. PSA prevention with novel fibrin sealant demonstrated a similar pattern to PSA development, with two stages of development evident: (i) tissue generation modelling occurring up to/including 16 hours post injury characterised by the inflammatory response and fibrin deposition and maturation; and (ii) tissue generation remodelling occurring from 16 hours onwards and characterised by tissue repair, collagen deposition and maturation and chemical mediation by TGF-P. However the extent and subsequent time taken for these changes to occur was significantly reduced. The prevention of PSAs and alterations of wound healing by novel fibrin sealant is most probably due to the sealant acting as a haemostat, as well as a physical barrier. Thus preventing fibrinous and subsequent fibrous PSA formation.

Mobile technologies have the potential to improve patient monitoring, medical decision making and in general the efficiency and quality of health delivery. They also pose new security and privacy challenges. The objectives of this work are to (i) Explore and define security and privacy requirements on the example of a post-surgical care application, and (ii) Develop and test a pilot implementation Post-Surgical Care Studies of surgical out- comes indicate that timely treatment of the most common complications in compliance with established post-surgical regiments greatly improve success rates. The goal of our pilot application is to enable physician to optimally synthesize and apply patient directed best medical practices to prevent post-operative complications in an individualized patient/procedure specific fashion. We propose a framework for a secure protocol to enable doctors to check most common complications for their patient during in-hospital post- surgical care. We also implemented our construction and cryptographic protocols as an iPhone application on the iOS using existing cryptographic services and libraries.

Background: Thousands of Canadians undergo cardiac surgery each year with the aim of relieving symptoms (e.g., angina) and improving health-related-quality-of-life (HRQoL). Despite the demonstrated symptom-related benefits of these surgeries, evidence suggests that the development of chronic post-surgical pain (CPSP) is a major clinical problem. To date, several perioperative factors have been examined for their potential to confer risk for CPSP. Purpose: The purpose of the study was to explore the association between preoperative moderate to severe anxiety and depressive symptoms; moderate to severe acute postoperative pain; and cumulative opioid dose consumption with the development of CPSP at six months and 12 months after cardiac surgery. Method: Design. This thesis was a prospective observational cohort sub-study of adults undergoing cardiac surgery in a tertiary care hospital setting (n=735), recruited from Hamilton Health Sciences, Canada over a five year period. Measures. The independent variables included state anxiety, depressive symptoms, acute postoperative pain intensity, and opioid dose consumption. At baseline, the Spielberger State-Trait Anxiety Inventory (STAI) assessed state anxiety and the Hospital Anxiety and Depression Scale (HADS) assessed depressive symptoms. The Brief Pain Inventory-Short Form (BPI-SF) assessed acute postoperative pain intensity on postoperative days three (in-hospital) and 30 (at home via telephone). All instruments have established reliability and validity in cardiac surgery patients (e.g., STAI Cronbach’s alpha (α) =0.82; HADS α=0.81; BPI-SF α=0.87). Medical records were reviewed and total dose of opioids consumed up to three days postoperatively, were collected via analgesic chart audit and converted into milligrams of parenteral morphine equivalent dose using standard dosage tables. Dependent variable. The primary outcome of CPSP was assessed dichotomously (i.e., yes/no) at six months and 12 months after cardiac surgery. If present, CPSP was assessed via the BPI-SF. At baseline, data was collected on pre-specified model covariates (e.g., age, sex). Data Analyses. Logistic regression was used to model the primary outcome with the presence of CPSP at six months and 12 months, while adjusting for model covariates. Secondary linear regression models were constructed to examine the effect of the independent variables on the severity of CPSP with statistical significance set at p-values <0.05. Results: The incidence of CPSP was 8.7% at six months and 4.1% at 12 months after cardiac surgery. Baseline demographics (i.e., age, sex) and medical status (i.e., diabetes mellitus) were significantly associated with the presence of CPSP. Moderate to severe preoperative anxiety was not significantly associated with CPSP at six months (adjusted OR 0.629, 95% CI [0.300, 1.322], p=0.222) or 12 months (adjusted OR 0.743, 95% CI [0.242, 2.285], p=0.604). Moderate to severe preoperative depressive symptom was not significantly associated with CPSP at six months (adjusted OR 0.676, 95% CI [0.152, 3.005], p=0.607) or 12 months (adjusted OR 3.216, 95% CI [0.835, 12.382], p=0.089). Acute postoperative pain rated as pain ‘right now’ on day three was significantly associated with CPSP at six months (adjusted OR 2.263, 95% CI [1.255, 4.081], p=0.007) and 12 months (adjusted OR 2.749, 95% CI [1.174, 6.441], p=0.020). Acute postoperative pain ‘right now’ on day 30 was significantly associated with CPSP at six months (adjusted OR 2.913, 95% CI [1.304, 6.505], p=0.009). Cumulative opioid dose consumed was significantly associated with the development of CPSP at six months (adjusted OR 1.001, 95% CI [1.000, 1.002], p=0.003) and 12 months (adjusted OR 1.001, 95% CI [1.000, 1.001], p=0.033) after cardiac surgery. Significance: The findings demonstrate that acute postoperative pain ‘right now’ and cumulative opioid dose consumed are risk factors for CPSP after cardiac surgery. These findings offer targets for nursing staff to identify potentially at-risk patients, implement evidence-based pain management strategies, as well as contribute to nursing-led research designed to target CPSP after cardiac surgery. / Dissertation / Doctor of Philosophy (PhD)

With chronic post surgical pain affecting up to one third of patients undergoing surgeries and the price of treatment being astoundingly high there has been a transition in research to investigate and identify risk factors. Through identification of risk factors new preventative measures can be taken to ensure better surgical outcomes. The role that psychosocial factors can play in the development of chronic post surgical pain has long been recognized yet its mechanisms are still unknown. We aim to investigate how environment can play a direct role in pain perception and sensitivity. We used a Chronic Mild Stress (CMS) paradigm to induce depression in 10 adult male mice, we used 10 control mice who were left in standard opti cages, and 10 enriched mice who were placed in large enrichment cages. CMS mice were exposed to a series of stressors and all mice underwent spared nerve injury surgery. During spared nerve injury the common peroneal and tibial branches of the sciatic nerve were severed while the sural branch was left intact. Overall well-being and pain threshold of mice were tested via Von Frey, Hot Plate, Heat Place Preference, Dynamic Weight Bearing, Hole Board, and Social Interaction. It was found that CMS mice experienced thermal hyperalgesia yet normal thermal threshold sensation. CMS mice also spent less time interacting with novel mice in social interaction, and less amount of time exploring the center of the hole board arena than control or enriched mice. While Von Frey results did not change over the course of the experiment, dynamic weight bearing results indicated spared nerve injury surgery was successful and produced chronic pain. Results indicate that environment plays a role in thermal pain perception and CMS affected overall well being of mice as CMS mice exhibited more timid and anxious behavior.

This diploma thesis focuses on information awareness among mothers of children hospitalized at surgical intensive care units. Four research questions were formulated on the basis of literature review. The theoretical part of this thesis gives an overview of basic facts concerning information awareness and care of children at surgical ICUs. Furthermore, it describes the way information is passed on in praktice. A part of the theoretical section also comprises of the list enumerating the most common diagnoses with which children found themselves to be placed at surgical ICUs and it contains, as well, the description of admittance of children for a surgical intervention, pre-surgical care, post-surgical care and discharge of children from hospital to homecare. Collection of data for the practical part of the diploma thesis was conducted at two intensive care units in the University Hospital in Motol, Prague, and UH Brno in the CR. Five respondents were intentionally selected from each ICU with whom semi-structured interviews were conducted, which are summarized in sub-chapter 4.2. The results of interviews with individual respondents were further subjected to analysis and summarized in summary tables. The Diploma thesis had two objectives. The first objective was to ascertain subjective information awareness of mothers about their children´s illnesses and possible complications or consequences related to these illnesses. We wanted to find out whether mothers were subjectively satisfied with information provided about thein children´s illnesses and possible complications or consequences related to these illnesses. We also wanted to discover whether they experienced any information deficit in this area and what were their most frequent questions to the medical personnel. It was ascertained through interviews that the majority of respondents was not satisfied with information provided. The second objective was to discover subjective information awareness pertaining to the period of hospitalization at surgical ICU and child´s subsequent homecare. We wanted to know whether mothers felt that they were kept informed enough about pre-surgical and post-surgical care of their child and whether or not they were satisfied with information pertaining to child´s subsequent homecare. We were also interested in whether or not they experienced any deficit of information received and what were their most frequent questions to the medical personnel. It was discovered through an analysis that the majority of respondents was not satisfied with information pertaining to pre-surgical care and complications which might have arised during the surgical intervention. As for information centred on the date of operation and possible duration of hospitalization most respondents were satisfied with it. Furthermore, the majority of respondents were satisfied with information provided about child´s subsequent homecare. We discovered that respondents were not informed satisfactorily by medical personnel about other contacts such as for clubs for parents, stoma clubs and centres of early intervention. It was possible to ascertain from the results that each respondent saw deficits in different areas of information provision as well. In the list of such information deficit areas are information about the character of surgical intervention, the ward rules, and the fact that doctors and nurses do not have enough time. Moreover, the respondents also perceived the deficit in sharing of information among medical personnel. On the basis of final results which point to experience of unsatisfactory information awareness among mothers about pre-surgical care for the child we developed in a written form the Information for parents about pre-surgical and post-surgical care brochure. We also prepared due to the fact that mothers sensed the lack of written information about the ward the Information for parents about the ward brochure.

CNPQ / The medication reconciliation process (RIM) have great impact in preventing adverse events and errors related to drugs and is a formal process of obtaining a complete and accurate listing of household medication that is compared to the hospital prescription list. The discrepancies found during this process can cause harm to patients. This becomes more serious when polymedicated patients, using three or more medications at home, undergo surgical procedure of urgency. OBJECTIVE. Evaluate occurrence of discrepancies in the pharmacotherapy of surgical patients at a hospital in the state of Sergipe. METHODOLOGY. This was an observational study of descriptive exploratory, cross-sectional study between August and November 2014, to assess the occurrence of discrepancies in the pharmacotherapy of patients admitted to the surgical hospital admission. Polymedicated patients were considered those who used three or more drugs. In the initial interview we consider as sources of information the patient himself, the companion, the domestic use of drugs led to hospitalization and consultation of the record. Discrepancies were classified as unintentional variation among the drugs used before admission and the prescribed medication list after surgery may be: failure of drugs, differences in dose, differences in the frequency / schedule of administration, duplicity therapy and interaction between medications. The data were tabulated and analyzed. RESULTS. No período do estudo 422 pacientes foram admitidos no internamento pós-cirúrgico. Desses, 80 (19%) atenderam ao critério de inclusão, composto por 43 (53,8%) mulheres e 37 (46,3%) homens, com média de idade 64,14 anos ± 17,0. O motivo de internação mais prevalente foi amputação de membro inferior ou superior 33 (41,3%); a média de medicamentos do domicílio foi 4,7 ± 1,9. Foi encontrado um total de 444 discrepâncias, com uma média por paciente de 5,5 ± 2,78, as mais prevalentes foram interação, que representou mais da metade de todas as discrepâncias identificadas, 53,4% (n=237) e a omissão que constituiu 25,7% (n=114). Foram realizadas 106 intervenções e apenas n=15 (14,2%) foram aceitas. CONCLUSION. Polymedicated patients undergoing surgery require special care since they are under the care of medical specialists focused on meeting the reason for his hospitalization. The study suggests that the discrepancies found may represent high risk for safety of these patients, a more effective process of identification of home therapy is necessary when the patient is subjected to hospitalization; some comorbidities are related to the large number of medications. Thus, actions to promote patient safety in hospital admission and reduce medication errors should be practiced. / O processo de reconciliação de medicamentos (RM) tem grande impacto na prevenção de eventos adversos e erros relacionados a medicamentos e consiste num processo formal de obtenção de uma lista completa e precisa dos medicamentos do domicílio que é comparada com a lista de prescrição hospitalar. As discrepâncias encontradas durante esse processo podem causar danos aos pacientes. Isso se torna mais grave quando pacientes polimedicados, em uso de três ou mais medicamentos no domicílio, são submetidos a procedimento cirúrgico de urgência. OBJETIVO. Avaliar ocorrência de discrepâncias na farmacoterapia de pacientes cirúrgicos em um hospital do Estado de Sergipe. METODOLOGIA. Foi realizado um estudo observacional do tipo exploratório descritivo, de delineamento transversal entre Agosto e Novembro de 2014, para avaliação da ocorrência de discrepâncias na farmacoterapia de pacientes admitidos no internamento cirúrgico do hospital. Foram considerados pacientes polimedicados, aqueles que faziam uso de três ou mais medicamentos. Na entrevista inicial consideramos como fontes de informação o próprio paciente, o acompanhante, os medicamentos de uso domiciliar levados a internação e a consulta ao prontuário. As discrepâncias foram classificadas como qualquer variação não intencional entre os medicamentos utilizados antes da admissão e a lista de medicamentos prescrita após a intervenção cirúrgica podendo ser: omissão de medicamentos, diferenças na dose, diferenças na frequência/horário de administração, duplicidade terapêutica e interação entre medicamentos. Os dados obtidos foram tabulados e analisados. RESULTADOS. No período do estudo 422 pacientes foram admitidos no internamento pós-cirúrgico. Desses, 80 (19%) atenderam ao critério de inclusão, composto por 43 (53,8%) mulheres e 37 (46,3%) homens, com média de idade 64,14 anos ± 17,0. O motivo de internação mais prevalente foi amputação de membro inferior ou superior 33 (41,3%); a média de medicamentos do domicílio foi 4,7 ± 1,9. Foi encontrado um total de 444 discrepâncias, com uma média por paciente de 5,5 ± 2,78, as mais prevalentes foram interação, que representou mais da metade de todas as discrepâncias identificadas, 53,4% (n=237) e a omissão que constituiu 25,7% (n=114). Foram realizadas 106 intervenções e apenas n=15 (14,2%) foram aceitas. CONCLUSÃO. Os pacientes polimedicados submetidos a cirurgia requerem cuidados especiais uma vez que estão sob cuidados de médicos especialistas focados no atendimento do motivo do seu internamento. O estudo sugere que as discrepâncias encontradas podem representar alto risco para segurança desses pacientes, sendo necessário um processo mais efetivo de identificação da terapia domiciliar quando o paciente é submetido a internação; algumas comorbidades estão relacionadas ao elevado número de medicamentos em uso. Assim, ações que promovam a segurança do paciente na admissão hospitalar e reduzam os erros de medicamentos devem ser praticadas.

Hospital Universitário Antonio Pedro / A micobacteriose pós-cirúrgica (MPC) vem emergindo nos últimos anos no Brasil e no mundo como uma infecção relacionada à assistência a saúde, representando um grave problema de saúde pública. Em 2006, vários casos foram informados à Secretaria de Estado de Saúde do Rio de Janeiro (SES/RJ). A partir de março daquele ano, teve início um trabalho conjunto dessa Secretaria e do Ministério da Saúde, que definiu diretrizes para a confirmação do surto/epidemia, para o levantamento das causas, para a identificação das espécies do patógeno envolvido e para estabelecer medidas de prevenção e controle. Este estudo teve como objetivo descrever os aspectos clínicos e sociodemográficos dos pacientes atendidos no Serviço de Infectologia do Hospital Universitário Antônio Pedro (HUAP), Universidade Federal Fluminense, com diagnóstico de MPC no período 2006-2009. Casuística e métodos: De abril de 2006 a junho de 2009 foram atendidos no Serviço de Infectologia do HUAP 125 pacientes encaminhados pela SES/RJ por serem casos suspeitos ou confirmados de micobacteriose não tuberculosa adquirida após procedimentos cirúrgicos. Os pacientes chegaram ao HUAP com a ficha própria de notificação de caso de MPC preenchida com os dados da identificação, do procedimento relacionado à infecção, da abordagem diagnóstica e da terapêutica prévia. O tratamento medicamentoso obedeceu às diretrizes estabelecidas pela SES/RJ e pela Agência Nacional de Saúde. Os dados contidos nestas fichas, bem como outras informações concernentes à evolução clínica, tratamento dispensado no HUAP e resposta terapêutica, foram inseridos em um banco de dados especialmente desenvolvido para a pesquisa. Resultados: A maior parte dos casos de MPC ocorreu em pacientes do sexo feminino (77,6%) e a colecistectomia laparoscópica foi o procedimento cirúrgico mais frequente (48,8%). A média do período de incubação foi de 41 dias e a mediana de 31 dias, O sinal clínico mais comum foi a presença de secreção (86,5%), seguida da de nodulações (65,6%). A maior parte dos casos apresentou lesões superficiais e múltiplas (44,8%). Em 45,6% dos casos foram colhidos suabes e tecido para cultura antes do início do tratamento e a positividade deste material foi de 43,5%, valor significantemente maior que o observado quando a coleta de material foi feita após o início do tratamento (16,7%). O tratamento com três fármacos (claritromicina, etambutol e terizidona) foi feito em 90,4% (113/125) dos pacientes, com duração média de 226 dias e mediana de 229 dias. Foram submetidos a pelo menos uma abordagem cirúrgica 77,6% (97/125) dos casos, principalmente aqueles que apresentavam lesões profundas (44/56). Efeitos adversos foram observados em 62,4% (78/125) dos casos, sendo boca amarga o mais frequente. Conclusão: Apesar do longo tempo de tratamento com múltiplos fármacos, a grande maioria dos pacientes aderiu ao tratamento e evoluiu para a cura sem recidivas. / Post-surgical mycobacteriosis (PSM) is emerging as a serious public health problem in Brazil and in the world. In 2006 a number of infections were reported to the Secretary of Health in the Rio de Janeiro State. Starting in March of this year, a joint effort was initiated by this Secretary and the Ministry of Health, in order to set up guidelines to confirm the outbreak/epidemic, to identify its causes, to identify the species of the pathogen involved, and to establish measures of prevention and control. The aim of this work was to describe the clinical and sociodemographic findings of the patients treated at the Infectious Diseases Service of Hospital Universitário Antônio Pedro (HUAP), Universidade Federal Fluminense, who had PSM from 2006 to 2009. Patients and Methods: From April 2006 to June 2009, 125 patients were referred by the Secretary of Health of the Rio de Janeiro State to HUAP with suspected or confirmed PSM. Each patient arrived at HUAP had a PSM case report form with data on identification, infection-related procedures, diagnostic approaches, and previous therapy. The treatment was defined by the Secretary of Health of the Rio de Janeiro State and the Health National Agency. The data from these case report forms, as well as other information associated with clinical evolution, treatment at HUAP, and therapeutic response were inserted into a database specially developed for this research. Results: Most PSM cases occurred in female patients (77.6%) and laparoscopic cholecystectomy was the most frequent surgery (48.8%). The mean incubation period was 41 days (median: 31 days). The most common presentation was drainage (86.5%) and nodules (65.6%). Most cases had multiple and superficial lesions (44.8%). Swab and tissue cultures were performed before treatment in 45.6% of the patients and their positivity was 43.5%, value significantly higher than that found when the specimens were obtained after the onset of treatment (16,7%). Most patients (90.4% - 113/125) were treated with a combined therapy using 3 drugs (clarithromycin, ethambutol and terizidone), with a mean duration of 226 days (median: 229 days). Surgical debridement was performed in 77.6% (97/125) of the cases, mainly in those with deep tissues lesions (44/56). Drug adverse effects occurred in 62.4% (78/125) of the cases, and bitter taste was the most common. Conclusion: In spite of multiple-drug and long-term treatment, most patients adhered to therapy and evolved to cure without relapses.

In this thesis, rodent models of chronic pain were used to explore analgesic mechanisms that may potentially be engaged in spinal and peripheral compartments by systemically-administered amitriptyline, a tricyclic antidepressant. The first project (Chapter 2) identified the roles of spinal adenosine A1 and serotonin 5-HT7 receptors, as well as of peripheral adenosine A1 receptors, in the acute antinociceptive effects of amitriptyline in mice. The second project (Chapter 3) examined the potential utility of amitriptyline as a preventive analgesic against persistent post-surgical pain, and involved perioperative administration of amitriptyline after peripheral nerve injury in rats. Changes in post-injury behavioural outcomes, as well as spinal noradrenergic sprouting, were assessed. Overall, spinal serotonergic pathways linked to adenosine A1 receptors, as well as peripheral adenosine A1 receptors, appear to be important in antinociception by amitriptyline. Preventive analgesia by this drug does not appear to result from anatomical changes in spinal noradrenergic pathways.
