Wall blocks for breast cancer in pregnant patients: saving general anaesthesia also benefits foetal wellness.

Although it is uncommon in general, breast cancer is the most commonly diagnosed cancer during pregnancy. Pregnant patients should receive treatment based on nonpregnant guidelines, with special adjustments for diagnosis, staging, oncology, and obstetrics. This situation is particularly concerning for the health of a long-awaited foetus, especially after medical intervention to aid fertilization. To ensure the baby's safety, it is best to conclude the pregnancy as soon as possible in many cases. We know this is not always possible. This case report discusses the application of the pecto-serratus plane block (PSP) in a patient at seven months gestation undergoing breast quadrantectomy due to the abrupt onset of breast cancer. This study is limited as it involves only one patient. However, it highlights the relevance of locoregional anaesthesia in para-physiological states such as pregnancy.
