Eficacia y seguridad del bloqueo de nervio supraescapular guiado por ultrasonido en pacientes con dolor crónico de hombro / Efficacy and safety of ultrasound-guided suprascapular nerve block in patients with chronic shoulder pain
Se realizaron 46 bloqueos. El 78,3% de los pacientes presentaron una disminución del dolor de al menos el 50% a los 2 días y el 47,8% al mes, con una diferencia estadísticamente significativa (p < 0,0001) entre las medianas de la EVA inicial, al segundo día y al mes. No se presentaron complicaciones.
A descriptive, prospective, follow-up study was conducted in a cohort of 46 patients with chronic shoulder pain disorder who received interventional treatment under ultrasound guidance at the Colombian Pain Institute between October 2011 and May 2012, with the objective of determining efficacy and safety of the procedure. Data were gathered before the procedure, and then two days later and one month after the procedure. Pain intensity was measured using the visual analogue scale (VAS).
Results:
Forty-six blocks were performed. Overall, 78.3% of the patients experienced at least 50% reduction of pain two days later, and 47.8% had pain relief after one month, with a statistically significant difference (p < 0.0001) between the starting VAS median score and the median scores on the second postoperative day and at one month. There were no complications.
Conclusions:
Ultrasound-guided suprascapular blockade is an effective and safe treatment option in patients with chronic shoulder pain.
