ABSTRACT
Abstract Objective To evaluate the prevalence of persistent pain in the postoperative period of fractures of the distal extremity of the radius, as well as to detect early signs of neuropathic pain to develop protocols for the prevention of chronic postoperative pain. Methods Prospective study, carried out with 56 patients who underwent open reduction and internal fixation of fractures of the distal extremity of the radius with a volar locking plate from March to September 2020. The patients were submitted to assessment of neuropathic pain and functional capacity through the Douleur Neuropathique 4 questionnaire (DN4) and Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH) questionnaires. Qualitative variables were compared using the Mann-Whitney U test and their correlation was analyzed using the Spearman Correlation and Equality of Two Proportions tests. Results A total of 43 patients aged between 18 and 66 years old were included in the present study; 39.5% of the participants scored ≥ 4 on the DN4 questionnaire. In relation to Quick-DASH, the average was 38.6. There was no statistically significant difference between the gender of the patient and the DN4 value (p= 0.921). There was also no statistical correlation between the quantitative variables DN4 and Quick-DASH (p= 0.061). Conclusions The prevalence of neuropathic pain in analyzed postoperative patients was significant, and the presence of signs and symptoms of neuropathic pain was a positive predictive factor for pain persistence beyond 2 months in 100% of cases. Thus, with early diagnosis of the neuropathic component of pain, associated with the nociceptive component, adequate pain control can be achieved, preventing its chronicity, and ensuring better rehabilitation.
RESUMO
Resumo Objetivo Avaliar a prevalência de dor persistente no pós-operatório de fratura da extremidade distal do rádio, assim como detectar precocemente sinais de dor neuropática com o intuito de desenvolver protocolos de prevenção da dor crônica pós-operatória. Métodos Estudo prospectivo, realizado com 56 pacientes submetidos a redução aberta e fixação interna de fratura da extremidade distal do rádio com placa volar bloqueada no período de março a setembro de 2020. Os pacientes foram submetidos a avaliação de dor neuropática e capacidade funcional através dos questionários Douleur Neuropathique 4 questionnaire (DN4) e Quick Disabilities of the Arm, Shoulder, and Hand (Quick-DASH, na sigla em inglês). As variáveis qualitativas foram comparadas pelo teste de Mann-Whitney e sua correlação foi analisada pelos testes de correlação de Spearman e de Igualdade de Duas Proporções. Resultados Foram incluídos no presente estudo 43 pacientes, com idades entre 18 e 66 anos; 39,5% dos participantes apresentaram pontuação ≥ 4 no questionário Douleur neuropathique 4 questionnaire (DN4). Em relação ao Quick-DASH, a média foi de 38,6. Não houve diferença estatística significante entre o sexo do paciente e o valor do DN4 (p= 0,921). Também não foi encontrada correlação estatística entre as variáveis quantitativas DN4 e Quick-DASH (p= 0,061). Conclusões A prevalência de dor neuropática nos pacientes pós-operatórios analisados foi significativa e a presença de sinais e sintomas de dor neuropática foi fator preditivo positivo para a persistência da dor além de 2 meses em 100% dos casos. Assim, com diagnóstico precoce do componente neuropático de dor, associado ao componente nociceptivo, é possível obter o controle adequado da dor, impedindo sua cronificação e garantindo uma melhor reabilitação.
