FUNDAMENTO: Técnicas cirúrgicas de revascularização miocárdica sem o uso de circulação extracorpórea (CEC) projetaram esperanças de resultados operatórios com menor dano sistêmico, menor ocorrência de complicações clínicas e menor tempo de internação hospitalar, gerando expectativas de menor custo hospitalar. OBJETIVO: Avaliar o custo hospitalar em pacientes submetidos à cirurgia de revascularização miocárdica com e sem o uso de CEC, e em portadores de doença multiarterial coronariana estável com função ventricular preservada. MÉTODOS: Os custos hospitalares foram baseados na remuneração governamental vigente. Acrescentaram-se aos custos uso de órteses e próteses, complicações e intercorrências clínicas. Consideraram-se o tempo e os custos de permanência na UTI e de internação hospitalar. RESULTADOS: Entre janeiro de 2002 e agosto de 2006, foram randomizados 131 pacientes para cirurgia com CEC (CCEC) e 128 pacientes sem CEC (SCEC). As características basais foram semelhantes para os dois grupos. Os custos das intercorrências cirúrgicas foram significativamente menores (p < 0,001) para pacientes do grupo SCEC comparados ao grupo CCEC (606,00 ± 525,00 vs. 945,90 ± 440,00), bem como os custos na UTI: 432,20 ± 391,70 vs. 717,70 ± 257,70, respectivamente. Os tempos de permanência na sala cirúrgica foram (4,9 ± 1,1 h vs. 3,9 ± 1,0 h), (p < 0,001) na UTI (48,2 ± 17,2 h vs. 29,2 ± 26,1h) (p < 0,001), com tempo de entubação (9,2 ± 4,5 h vs. 6,4 ± 5,1h) (p < 0,001) para pacientes do grupo com e sem CEC, respectivamente. CONCLUSÃO: Os resultados permitem concluir que a cirurgia de revascularização miocárdica, sem circulação extracorpórea, proporciona diminuição de custos operacionais e de tempo de permanência em cada setor relacionado ao tratamento cirúrgico.

BACKGROUND: Surgical techniques of myocardial revascularization without the use of extracorporeal circulation (ECC) have raised hopes of attaining operative results with less systemic damage, lower occurrence of clinical complications and shorter hospital stay duration, generating expectations of lower hospital costs. OBJECTIVE: To evaluate the hospital costs in patients submitted to myocardial revascularization with and without ECC and in those with stable multiarterial coronary disease with preserved ventricular function. METHODS: The hospital costs were based on the existing governmental reimbursement. The costs included that of ortheses and prostheses and clinical complications. The time and costs of ICU stay and hospital stay duration were considered. RESULTS: Between January 2002 and August 2006, 131 patients were randomized to surgery with ECC (SECC), whereas 128 were randomized to surgery without ECC (WECC). The basal characteristics were similar for both groups. The costs of surgical complications were significantly lower (p < 0.001) in patients from the WECC when compared to the SECC group (606.00 ± 525.00 vs. 945.90 ± 440.00), as well as ICU costs: 432.20 ± 391.70 vs. 717.70 ± 257.70, respectively. The duration of the operating room stay were 4.9 ± 1.1 h vs. 3.9 ± 1.0 h, p < 0.001; at the ICU it was 48.2 ± 17.2 h vs. 29.2 ± 26.1h) (p < 0.001), with intubation time of 9.2 ± 4.5 h vs. 6.4 ± 5.1h, p < 0.001 for patients from the group with and without ECC, respectively. CONCLUSION: The present study allowed us to conclude that the myocardial revascularization surgery without extracorporeal circulation results in the decrease of operational costs and duration of the stay in each section related to the surgical treatment.

FUNDAMENTO: Técnicas de cirurgia de revascularização miocárdica (RM) sem o uso de circulação extracorpórea (CEC) possibilitou resultados operatórios com menor dano sistêmico, menor ocorrência de complicações clínicas, menor permanência na sala de terapia intensiva e também no tempo de internação, gerando expectativas de melhor qualidade de vida (QV) dos pacientes. OBJETIVO: Avaliar a QV em pacientes submetidos à cirurgia de revascularização com e sem CEC. MÉTODOS: Em pacientes com doença multiarterial coronariana (DAC) estável e função ventricular preservada, aplicou-se o Short-Form Health Survey (SF-36) Questionnaire antes da cirurgia e depois de 6 e 12 meses. RESULTADOS: Entre janeiro de 2002 e dezembro de 2006, foram randomizados 202 pacientes para cirurgia de RM. As características demográficas clínicas laboratoriais e angiográficas foram semelhantes nos dois grupos. Desses pacientes, 105 foram operados sem CEC e 97 com CEC. Na evolução, 22 pacientes sofreram infarto, 29 relataram angina, um reoperou, 3 tiveram AVC e nenhum morreu. A avaliação da QV mostrou similaridade nos dois grupos em relação ao componente físico e mental. Todavia, encontrou-se significativa melhora da capacidade funcional e percepção do aspecto físico nos pacientes do sexo masculino. Além disso, um expressivo número de pacientes dos dois grupos retornou ao trabalho. CONCLUSÃO: Em todos os pacientes estudados, observaram-se melhora progressiva da qualidade de vida e retorno precoce ao trabalho, independentemente da técnica cirúrgica empregada. Exceto pela melhor percepção da capacidade funcional e do aspecto físico experimentado pelos homens, não houve diferença estatística nos resultados dos demais domínios alcançados pelos dois grupos estudados.

BACKGROUND: Coronary artery bypass grafting techniques without using cardiopulmonary bypass (off-pump CABG) result in less systemic damage, less clinical complications, less time spent in the intensive care unit, and shorter hospital stays, thereby raising the perspective of improved quality of life (QOL) for patients. OBJECTIVE: To assess quality of life in patients who underwent on-pump and off-pump CABG. METHODS: The Short-Form Health Survey (SF-36) Questionnaire was administered to patients with stable multivessel coronary artery disease (CAD) and preserved ventricular function before and at six and 12 months after surgery. RESULTS: Between January 2002 and December 2006, a total of 202 patients were randomized to either on-pump or off-pump CABG. Demographic, clinical, laboratory, and angiographic characteristics were similar in both groups. One hundred and five patients underwent off-pump CABG and 97 underwent on-pump CABG. In the postoperative course, 22 patients had myocardial infarction, 29 reported angina, one was reoperated, and three experienced stroke. No patient died. Quality of life, as measured by the SF-36 questionnaire, was shown to be similar in both groups regarding physical and mental components. However, male patients showed a significant improvement in physical functioning and role limitations due to physical problems. Also, a large number of patients in both groups returned to work. CONCLUSION: Progressive enhancement in quality of life and early return to work were observed for all patients, regardless of the surgical technique used. Save for a greater improvement in physical functioning and role limitations due to physical problems experienced by male patients, no statistically significant differences were found in the other domains between groups.
