Abstract: | Ultrasound is a particularly valuable imaging technique when performing nerve blocks at the cervical level. High-frequency probes provide high-quality resolution and are safe in skilled hands. Typically, interventions performed at the cervical level have been carried out with the help of x-rays, with the corresponding disadvantages such as the exposure to radiation and the inherent inability to observe radiotransparent structures such as blood vessels and nerves. Ultrasound allows us to visualize soft tissues and guide the tip of the needle to our target, without harming particularly delicate structures found in the path of the needle. This is important in nerve root blocks where the identification of periradicular nerves is crucial for the safety of the block itself. Likewise, ultrasound allows us to manipulate the needle with greater precision in the correct location; as is the case in cervical sympathetic nerve block where we can observe the injection of the liquid behind the prevertebral fascia and in front of the fascia of the longus colli muscle. In this article, we describe the most frequent techniques used in the pain clinic to treat headache and cervical pain, with special emphasis on the safety of the procedure. |
