Abstract Introduction: The majority of women having planned cesarean section receive spinal anesthesia for the procedure. Typically, spinal opioids are administered during the same time as a component of multimodal analgesia to provide pain relief in the 16-24 h period postoperatively. The quadratus lumborum block is a regional analgesic technique that blocks T5-L1 nerve branches and has an evolving role in postoperative analgesia for lower abdominal surgeries and may be a potential alternative to spinal opioids. If found effective, it will have the advantage of a reduction in opioid associated adverse effects while providing similar quality of analgesia. Methods: We performed bilateral quadratus lumborum block in 3 women who received a spinal anesthetic for a cesarean delivery and evaluated their post-operative opioid consumption and patient satisfaction. Results: In all 3 patients, there was no additional opioid consumption during the first 24 h after the block. Numeric Rating Scale (NRS) for pain was less than 6 for the first 24 h. Women were all very satisfied with the quality of pain relief. Discussion: Quadratus lumborum block may be a promising anesthetic adjuvant for post-cesarean analgesia. Further randomized controlled trials are needed to compare the efficacy of the quadratus lumborum block with intrathecal opioids.

Resumo Introdução: A maioria das mulheres agendadas para cesariana recebe anestesia raquidiana para o procedimento. Tipicamente, os opioides administrados por via espinhal (VE) são administrados ao mesmo tempo como um componente da analgesia multimodal para proporcionar alívio da dor no período pós-operatório de 16-24 horas. O bloqueio do quadrado lombar (QL) é uma técnica de analgesia regional que bloqueia os ramos nervosos T5- L1 e tem um papel crescente na analgesia pós-operatória de cirurgias abdominais inferiores, pode ser uma potencial opção para os opioides VE. Se for considerado eficaz, esse bloqueio terá a vantagem de uma redução nos efeitos adversos associados aos opioides e proporcionará qualidade semelhante de analgesia. Métodos: O bloqueio bilateral do quadrado lombar foi feito em três mulheres que receberam raquianestesia para parto cesário e o consumo de opioides no pós-operatório e a satisfação das pacientes foram avaliados. Resultados: Em todas as três pacientes, não houve consumo adicional de opioide durante as primeiras 24 horas após o bloqueio. A escala de avaliação numérica (EAN) para dor foi inferior a 6 durante as primeiras 24 horas. Todas as mulheres ficaram muito satisfeitas com a qualidade do alívio da dor. Discussão: O bloqueio do QL pode ser um adjuvante promissor para analgesia pós-cesariana. Estudos randomizados e controlados são necessários para comparar a eficácia do bloqueio do quadrado lombar com opioides administrados por via intratecal.
