ReviewInjection pressures measuring for a safe peripheral nerve block.
The performance of a precise and safe peripheral nerve blockade (PNB) can currently rely on the aid of the ultrasounds and nerve stimulators. The injection pressure monitoring may be beneficial to perform a safer procedure. This review focuses on the pressures measured during PNB among studies conducted on animal, and human models. ⋯ So it is desirable to make further studies in order to assess them. In the future, the monitoring of the pressure could allow the use of a minimal quantity of anesthetic, empowering the safety of the nerve blocks. Moreover, the sensitive system should not be invasive and it should not hinder the job of the anesthetists.

Pain relief for posterior fossa craniotomies as well as occipital neuralgia, are indications for the use of the greater occipital nerve block in children. The greater occipital nerve originates from the C2 spinal nerve and is accompanied by the occipital artery as it supplies the posterior scalp. ⋯ In infants, the greater occipital nerve can be blocked approximately 23 mm from the external occipital protuberance, medial to the occipital artery. This distance is equal to the width of the medial three fingers at the proximal interphalangeal joint of the patient.

Lumbar spine fusion with anterior (ALIF) or lateral (LLIF) approach is a moderately painful procedure associated with significant length of hospital stay (LoS) and opioid requirements. We developed an opioid-sparing analgesic pathway of care for ALIF and LLIF, featuring transversus abdominis plane (TAP) block. In this study, we assessed the feasibility of performing the TAP block as an analgesic adjunct for ALIF or LLIF. ⋯ Applying TAP block to spine surgery is a novel pain management strategy. This study demonstrates high patient acceptance and the general safety of the technique. Although lacking a control arm, these results also provide preliminary data supporting efficacy.
