Abstract
Objectives

Achieving adequate perioperative analgesia can be challenging in patients undergoing breast surgeries due to the complex nerve supply of the breast and axilla. The study aims to investigate the efficacy of ESPB in comparison to conventional regional anesthesia techniques (TPVB and PECS).

Methods

Eighty female patients who were scheduled for elective MRM, with ASA score I–II, and aged between 18 and 60 years, were included in the study. Patients were randomized into four groups, the TPVB, PECS, ESPB, and the control group. All patients in either block groups received 25 ml bupivacaine 0.25% with ultrasound guidance. The control group received only opioids for perioperative pain management. The patients were observed for 48 h after surgery for the duration of analgesia (primary outcome).

Results

ESPB has a shorter duration of analgesia than PECS block with no significant statistical difference compared with group TPVB. Morphine consumption is increased in ESPB compared to the PECS group, with an insignificant difference compared to group TPVB. There was an insignificant difference between the groups concerning hemodynamics and complications, with one pneumothorax case reported in the TPVB group.

Conclusion

PECS and ESPB represent a good alternative to TPVB for post-mastectomy analgesia with a superior analgesic effect of PECS block regarding opioid consumption, duration of the analgesia, and VAS score.

Resumen
Objetivos

Lograr la analgesia perioperatoria adecuada puede ser difícil en los pacientes sometidos a cirugías de mama, debido a la compleja inervación de la mama y la axila. El objetivo delestudio es investigar la eficacia de bloqueo del plano del músculo erector de la columna (ESPB) en comparación con las técnicas anestésicas regionales convencionales (bloqueo paravertebral torácico [TPVB] y bloqueo del nervio pectoral [PECS] ecoguiado).

Métodos

Se incluyó en el estudio a 80 mujeres programadas para MRM electiva, con puntuación ASA I–II, y edades comprendidas entre 18 y 60 años. Se aleatorizó a las pacientes en cuatro grupos: TPVB, PECS, ESPB y grupo control. Todas las pacientes de los grupos de bloqueo recibieron 25 ml de bupivacaína al 0,25% mediante guía ecográfica. El grupo control recibió únicamente opioides para el manejo del dolor perioperatorio. Se observó a las pacientes durante 48 horas postoperatorias, para medir la duración de la analgesia (resultado primario).

Resultados

ESPB reflejó una menor duración de la analgesia en comparación con el bloqueo PECS, sin diferencia estadísticamente significativa en comparación con el grupo TPVB. El consumo de morfina se incrementó en ESPB en comparación con el grupo PECS, con una diferencia insignificante en comparación con el grupo TPVB. Se produjo una diferencia no significativa entre los grupos en términos de hemodinámica y complicaciones, reportándose un caso de neumotórax en el grupo TPVB.

Conclusión

PECS y ESPB representan una buena alternativa a TPVB para analgesia post-mastectomía, reflejando el bloqueo PECS un efecto analgésico superior en cuanto a consumo de opioides, duración de la analgesia, y puntuación EVA.
