Resumo

JUSTIFICATIVA E OBJETIVOS: O Brasil ocupa o segundo lugar entre os países com maiores taxas de cesariana no mundo. Pouco se sabe a respeito das consequências futuras desse procedimento sobre a saúde materna. Este estudo investigou a influência da técnica anestésico-cirúrgica e da analgesia pós-operatória no aparecimento de dor crônica após três meses da cesariana. MÉTODO: Este estudo prospectivo randomizado foi feito em 443 pacientes submetidas a cesariana (eletiva e urgente), com diferentes doses de bupivacaína 0,5% hiperbárica e opioides na raquianestesia. Os grupos foram: G1- 8 mg bupivacaína hiperbárica + 2,5 mg sufentanil + 100 mg morfina; G2- 10 mg bupivacaína hiperbárica + 2,5 mg sulfentanil + 100 mg morfina; G3- 12,5 mg bupivacaína hiperbárica + 100 mg morfina; G4- 15 mg bupivacaína hiperbárica + 100 mg morfina; G5- 12,5 mg bupivacaína hiperbárica + 100 mg morfina (sem anti-inflamatório perioperatório). Dor em repouso e em movimento foram avaliadas no pós-operatório imediato. Contato telefônico foi feito, após três meses do procedimento cirúrgico, para identificação das pacientes com dor crônica. RESULTADOS: A incidência de dor crônica nos grupos foi: G1 = 20%; G2 = 13%; G3 = 7,1%; G4 = 2,2% e G5 = 20,3%. Pacientes que referiram escores de dor mais elevados no período pós-operatório tiveram maior incidência de dor crônica (p < 0,05). CONCLUSÃO: A incidência de dor crônica diminui com o emprego de doses maiores de anestésicos locais e uso de anti-inflamatórios não hormonais. Escores mais elevados de dor no período pós-operatório tiveram associação com aparecimento de dor crônica após três meses da cesariana.

Abstract

BACKGROUND AND OBJECTIVES: Brazil ranks second among countries with the highest rates of cesarean section in the world. Little is known about the future consequences of this procedure on maternal health. This study investigated the influence of anesthetic/surgical technique and postoperative analgesia on the onset of chronic pain after three months of cesarean section. METHOD: This is a prospective randomized study of 443 patients undergoing cesarean section (elective and emergency), with different doses of hyperbaric bupivacaine 0.5% and opioids in spinal anesthesia. Patients were alocated into five groups as follow: G1 received hyperbaric bupivacaine (8 mg), sufentanil (2.5 µg), and morphine (100 µg); G2 received hyperbaric bupivacaine (10 mg), sufentanil (2.5 µg), and morphine (100 µg); G3 received hyperbaric bupivacaine (12.5 mg) and morphine (100 µg); G4 received hyperbaric bupivacaine (15 mg) and morphine (100 µg); G5 received hyperbaric bupivacaine (12.5 mg) and morphine (100 µg), without perioperative anti-inflammatory. Pain at rest and in movement were evaluated in the immediate postoperative period. Phone contact was made after three months of surgery for identification of patients with chronic pain. RESULTS: The incidence of chronic pain in the groups was G1 = 20%; G2 = 13%; G3 = 7.1%; G4 = 2.2%, and G5 = 20.3%. Patients who reported higher pain scores in the postoperative period had a higher incidence of chronic pain (p < 0.05). CONCLUSION: The incidence of chronic pain decreases with higher doses of local anesthetics and use of anti-inflammatory drugs. The higher pain scores in the postoperative period were associated with chronic pain development after three months of cesarean section.
