Ocular risk management in patients undergoing general anesthesia: an analysis of 39,431 surgeries

OBJECTIVE: This study sought to describe and analyze ocular findings associated with nonocular surgery in patients who underwent general anesthesia. METHODS: The authors retrospectively collected a series of 39,431 surgeries using standardized data forms. RESULTS: Ocular findings were reported in 9 cases (2.3:10,000), which involved patients with a mean age of 58.9±19.5 years. These cases involved patients classified as ASA I (33%), ASA II (55%) or ASA III (11%). General anesthesia with propofol and remifentanil was used in 4 cases, balanced general anesthesia was used in 4 cases, and regional block was used in combination with balanced general anesthesia in one case. Five patients (55%) underwent surgery in the supine position, one patient (11%) underwent surgery in the lithotomy position, two patients (22%) underwent surgery in the prone position, and one patient (11%) underwent surgery in the lateral position. Ocular hyperemia was detected in most (77%) of the 9 cases with ocular findings; pain/burning of the eyes, visual impairment, eye discharge and photophobia were observed in 55%, 11%, 11% and 11%, respectively, of these 9 cases. No cases involved permanent ocular injury or vision loss. CONCLUSION: Ophthalmological findings after surgeries were uncommon, and most of the included patients were relatively healthy. Minor complications, such as dehydration or superficial ocular trauma, should be prevented by following systematic protocols that provide appropriate ocular occlusion with a lubricating ointment and protect the eye with an acrylic occluder. These procedures will refine the quality of anesthesia services and avoid discomfort among patients, surgeons and anesthesia staff. .

Cataract surgery: emotional reactions of patients with monocular versus binocular vision / Cirurgia de catarata: aspectos emocionais de pacientes com visão monocular versus binocular

PURPOSE: To analyze emotional reactions related to cataract surgery in two groups of patients (monocular vision - Group 1; binocular vision - Group 2). METHODS: A transversal comparative study was performed using a structured questionnaire from a previous exploratory study before cataract surgery. RESULTS: 206 patients were enrolled in the study, 96 individuals in Group 1 (69.3 ± 10.4 years) and 110 in Group 2 (68.2 ± 10.2 years). Most patients in group 1 (40.6%) and 22.7% of group 2, reported fear of surgery (p<0.001). The most important causes of fear were: possibility of blindness, ocular complications and death during surgery. The most prevalent feelings among the groups were doubts about good results and nervousness. CONCLUSION: Patients with monocular vision reported more fear and doubts related to surgical outcomes. Thus, it is necessary that phisycians considers such emotional reactions and invest more time than usual explaining the risks and the benefits of cataract surgery.Ouvir.

OBJETIVO: Verificar reações emocionais relacionadas à cirurgia de catarata entre pacientes com visão monocular (Grupo 1) e binocular (Grupo 2). MÉTODOS: Foi realizado um estudo tranversal, comparativo por meio de um questionário estruturado respondido por pacientes antes da cirurgia de catarata. RESULTADOS: A amostra foi composta de 96 pacientes no Grupo 1 (69.3 ± 10.4 anos) e 110 no Grupo 2 (68.2 ± 10.2 anos). Consideravam apresentar medo da cirugia 40.6% do Grupo 1 e 22.7% do Grupo 2 (p<0.001) e entre as principais causas do medo, a possibilidade de perda da visão, complicações cirúrgicas e a morte durante o procedimento foram apontadas. Os sentimentos mais comuns entre os dois grupos foram dúvidas a cerca dos resultados da cirurgia e o nervosismo diante do procedimento. CONCLUSÃO: Pacientes com visão monocular apresentaram mais medo e dúvidas relacionadas à cirurgia de catarata comparados com aqueles com visão binocular. Portanto, é necessário que os médicos considerem estas reações emocionais e invistam mais tempo para esclarecer os riscos e benefícios da cirurgia de catarata.

Cancelamento de cirurgias de catarata em um hospital público de referência / Cancellation of cataract surgery in a public hospital

OBJETIVO: Analisar a incidência e causas de cancelamento de cirurgias de catarata em um hospital público de referência. MÉTODOS: Trata-se de um estudo retrospectivo em que foram analisados o número de cancelamentos de facectomias durante o ano de 2009. Foram analisados sexo, idade, tipo de procedimento suspenso (facoemulsificação ou extração extracapsular do cristalino), tipo de anestesia, convênio (Sistema Único de Saúde ou convênio/particular) e motivo de suspensão da cirurgia (causas clínicas, institucionais ou pessoais). RESULTADOS: Foram agendadas no período 2.965 cirurgias de catarata, havendo 650 cancelamentos (21,92%). Dentre as principais razões para a suspensão do procedimento destacaram-se as causas clínicas (86,90%). Os meses de inverno apresentaram os maiores índices de suspensão de cirurgias de catarata. CONCLUSÃO: A taxa de cancelamento de cirurgia de catarata em serviços públicos parece ser a mesma que há 10 anos. A principal causa de suspensão deve-se por condições clínicas (hipertensão, diabetes, falta de exames, etc.).

PURPOSE: To report the incidence and causes of cataract surgery cancellations in a public hospital. METHODS: This is a retrospective study, which examined the number of cancellations of cataract surgery during 2009. We analyzed the type of procedure suspended (phacoemulsification or extracapsular extraction), type of anesthesia, gender, age, covenant (public/private) and the main reasons for suspension of the surgeries (clinical causes, institutional or personal). RESULTS: We analyzed 2,965 scheduled cataract surgeries, with 650 cancellations (21.92%). The main reason for the suspension of the procedure was clinical causes (86.90%). The winter months had the highest suspension rates of cataract surgery. CONCLUSION: The cancellation rate of cataract surgery in Brazilian public system seems to be the same as 10 years ago. The main cause of the suspension should be in clinical conditions (hypertension, diabetes, lack of exams, etc.).

Dificuldades de acesso ao tratamento de pacientes com indicação de cirurgia de catarata nos Sistemas de Saúde Público e Privado / Difficulties in access to treatment for patients undergoing cataract surgery in public and private health systems

OBJETIVO: Estimar o valor dos Projetos Catarata para a comunidade, identificando características e dificuldades de acesso ao diagnóstico e ao tratamento da catarata na rotina de atendimento de diversos Sistemas de Saúde. MÉTODOS: Durante uma campanha de catarata realizada em um hospital universitário foi aplicado um questionário de múltipla escolha somente aos pacientes selecionados para a cirurgia de catarata. Foram avaliadas, dentre outras, as seguintes variáveis: acesso prévio à consulta oftalmológica (serviço público ou privado); motivo(s) para a não realização da cirurgia no serviço inicial. RESULTADOS: Foram avaliados 627 pacientes com diagnóstico de catarata. A maioria 595 (95 por cento) já havia consultado um oftalmologista previamente, sendo que em 63 por cento das situações (375 pacientes) a consulta havia sido realizada há menos de um ano. A última avaliação oftalmológica foi realizada pelo Sistema Único de Saúde (SUS) em 52 por cento dos casos (307 pacientes), e entre estes, a fila de espera foi apontada pela maioria como sendo a causa da não realização da cirurgia. Com relação aos pacientes previamente atendidos em serviços privados, o motivo da não realização da cirurgia foi o custo da cirurgia e custo da lente intraocular. CONCLUSÃO: Os resultados deste estudo sugerem que a rotina de atendimento oftalmológico no SUS em São Paulo não está preparada para atender a demanda por cirurgias de catarata, e o sistema de saúde privado ainda exclui uma parcela da população que possuí acesso à consulta clínica da cirurgia de catarata. É importante a continuidade da realização de campanhas comunitárias para atender a população que não teria como acessar a cirurgia pelas vias convencionais.

PURPOSE: To identify the difficulties in access to diagnosis and treatment of cataract in patients attended during a cataract campaign. METHODS: A questionnaire was administered to patients selected for cataract surgery. We evaluated, among others, the following variables: prior access to ophthalmologists (public or private), reason(s) for not having surgery early in the initial service, the average cost charged by cataract surgery and intraocular lens (IOL) (private services and agreements). RESULTS: A total of 627 patients was evaluated. Most of them - 595 (95 percent) had previously attended an ophthalmologist, and in 63 percent of cases (375 patients) the consultation had been held for less than a year. The last evaluation was performed by the Brazilian Public Health System (SUS) in 52 percent of the cases (307 patients). Regarding the reason for not having surgery in the initial service, the high cost of the surgery (R$ 2.000 - R$ 4.000) and the cost of IOLs (R$ 1.000 - R$ 1.500) was the main obstacle for most attended services and private covenants. CONCLUSION: The results of this study suggest that the routine of ophthalmologic care in SUS at São Paulo is not prepared to answer the demand for cataract surgeries and private healthcare system still excludes a portion of the population. It is important to continue the implementation of community campaigns to serve the population that would be unable to access the surgery through conventional ways.

Phacoemulsification versus extracapsular extraction: governmental costs

PURPOSE: To evaluate the governmental costs of patients undergoing phacoemulsification and extracapsular cataract extraction at a public hospital in a developing country. METHODS: A prospective study was conduced with 205 patients. The subjects were randomized for cataract surgery using either phacoemulsification or extracapsular cataract extraction techniques. RESULTS: Of the 205 patients, 101 patients were submitted to phacoemulsificationand 104 patients were submitted to extracapsular cataract extraction. Brazilian Health Care System expenditures for the surgery and the postoperative period were US$ 95.49 more in the phacoemulsification group than in the extracapsular cataract extractiongroup. If we take into account Social Security expenditures, then we estimate that the average difference for the total direct cost for the government for the surgery and the postoperative period for both procedures was US$ 50.91 or approximately half of the initial difference in cost for the phacoemulsification surgery. The total cost of cataract surgery for the government (excluding social security) was estimated at US$ 258.79 for extracapsular cataract extraction and US$ 309.70 for phacoemulsification per patient. Focusing only on working patients, the total cost was US$ 342.21 for phacoemulsification and US$ 587.71 for extracapsular cataract extraction, a difference of US$ 245.50. This difference can be considered monetarily and socially justifiable when the benefits of the surgical technique are evaluated. CONCLUSION: Under the conditions of this study, we observed that phacoemulsification was an efficient procedure with regard to the impact on public health care system, when all costs are assessed comprehensively, mainly for subjects with regular jobs.
