Abstract
Objective

The use of interfascial plane blocks for postoperative analgesia is becoming more widespread because they are easier to perform and have fewer complications. This prospective, single-blind, randomized controlled study compares the efficacy of serratus plane block (SPB) and erector spinae plane block (ESPB) for postoperative analgesia in patients undergoing unilateral breast surgery.

Methods

Seventy-four ASA I–II patients aged 18–65 years who underwent elective unilateral breast surgery were included in the study. After exclusion, 70 patients were randomized to receive SPB (n=35) or ESPB (n=35). In both groups, nerve blocks were administered under ultrasound guidance with 25ml of 0.25% bupivacaine. Postoperative pain (assessed using the visual analogue scale [EVA]), duration of analgesia, tramadol consumption, and incidence of complications were recorded.

Results

There were no significant differences in EVA scores between groups. However, duration of analgesia was significantly higher in the ESPB group (395.6±141.9min) vs the SPB group (290.3±148.3min) (p=0.003). Total tramadol consumption over 24h was similar between groups: 70.9±48.6mg in the SPB group and 70.3±50.5mg in the ESPB group. Minimal postoperative complications, including nausea and vomiting, were noted with no significant difference between groups.

Conclusion

Both SPB and ESPB were safe and provided similar postoperative analgesia in patients undergoing unilateral breast surgery. ESPB provides longer lasting analgesia, and therefore improves patient comfort in the early postoperative period.

Resumen
Objetivo

El uso de bloqueos en el plano interfascial para analgesia postoperatoria se ha generalizado cada vez más, debido a que son más fáciles de realizar y tienen menores complicaciones. Este estudio controlado aleatorizado prospectivo y uniciego compara la eficacia del bloqueo del plano de los músculos serrato (SPB) y erector de la columna (ESPB) para analgesia postoperatoria en pacientes que reciben cirugía unilateral de la mama.

Métodos

En el estudio se incluyeron setenta y cuatro pacientes ASA I-II de edades comprendidas entre 18 y 65 años sometidas a cirugía unilateral de la mama. Tras la exclusión, se aleatorizó a 70 pacientes para que recibieran SPB (n=35) o ESPB (n=35). En ambos grupos, los bloqueos nerviosos fueron administrados mediante guía ecográfica con 25ml de bupivacaína al 0,25%. Se registraron el dolor postoperatorio (evaluado mediante la escala visual analógica [EVA]), la duración de la analgesia, el consumo de tramadol y la incidencia de complicaciones.

Resultados

No existieron diferencias significativas en las puntuaciones EVA entre los grupos. Sin embargo, la duración de la analgesia fue significativamente más alta en el grupo ESPB (395,6±141,9 minutos) en comparación con el grupo SPB (290,3±148,3 minutos) (p=0,003). El consumo de tramadol total a lo largo de 24 horas fue similar entre ambos grupos: 70,9±48,6mg en el grupo SPB y 70,3±50,5mg en el grupo ESPB. Se advirtieron complicaciones postoperatorias mínimas, incluyendo náuseas y vómitos, sin diferencia significativa entre los grupos.

Conclusión

Tanto SPB como ESPB fueron seguros y aportaron analgesia postoperatoria similar postoperativa en las pacientes sometidas a cirugía unilateral de la mama. ESPB aporta una analgesia de mayor duración, mejorando por tanto la comodidad del paciente en el periodo postoperatorio temprano.
