“…31 Real-time ultrasound-guided LP is most often performed using a longitudinal (in-plane), paramedian approach. [31][32][33][34][35][36][37] One prospective study using a conventional curvilinear transducer and a longitudinal paramedian approach demonstrated a 97% success rate with a median of 3 needle passes (interquartile range 1-6). 34 Although small studies describing real-time ultrasound guidance appear promising, lumbar spine mapping to mark the needle insertion site is currently the most common technique with the largest body of supporting evidence.…”

Purpose of review: To review the literature and describe techniques to use ultrasound to guide performance of lumbar puncture (LP). Recent findings:Ultrasound evaluation of the lumbar spine has been shown in randomized trials to improve LP success rates while reducing the number of attempts and the number of traumatic taps. Summary: Ultrasound mapping of the lumbar spine reveals anatomical information that is not obtainable by physical examination, including depth of the ligamentum flavum, width of the interspinous spaces, and spinal bone abnormalities, including scoliosis. Using static ultrasound, the lumbar spine anatomy is visualized in transverse and longitudinal planes and the needle insertion site is marked. Using real-time ultrasound guidance, the needle tip is tracked in a paramedian plane as it traverses toward the ligamentum flavum. Future research should focus on efficient methods to train providers, costeffectiveness of ultrasound-guided LP, and the role of new needle-tracking technologies to facilitate the procedure. Neurol Clin Pract 2016;6:358-368 P oint-of-care ultrasound is being increasingly used to guide bedside procedures. For certain bedside procedures, such as central venous catheterization, use of ultrasound guidance is now considered the standard of care. For other procedures, such as lumbar puncture (LP), ultrasound can facilitate performance of the procedure by revealing underlying anatomy. Although many clinicians can perform LP based on landmarks with high success rates, an increasing body of evidence supports the use of ultrasound guidance, particularly in obese patients with less palpable landmarks. A recent study demonstrated a 19% failure rate of LPs performed in a neurology clinic when landmarks alone were used. A strong correlation between body mass index (BMI) and procedure failure was shown with half of the failed LPs in patients with a BMI .35.

“…This theoretically confers an increased margin of safety as the needle path and/or tip position can be superimposed on the image of the underlying tissues. Real-time needle guidance has been shown in several studies to improve success rates and reduce procedure times for a number of interventional tasks [25][26][27][28][29][30][31][32].…”

Ultrasound-guided procedures are increasingly common in a variety of acute care settings, such as the operating room, critical care unit and emergency room. However, accurate judgment of needle tip position using traditional ultrasound technology is frequently difficult, and serious injury can result from inadvertently advancing beyond or through the target. Needle navigation is a recent innovation that allows the clinician to visualize the needle position and trajectory in real time as it approaches the target. A novel ultrasound machine has recently been introduced that is portable and designed for procedural guidance. The eZono 4000™ features an innovative needle navigation technology that is simple to use and permits the use of a wide range of commercially available needles, avoiding the inconvenience and cost of proprietary equipment. This article discusses this new ultrasound machine in the context of other currently available ultrasound machines featuring needle navigation.

“…Since then multiple case studies and case series have been published on real time needle guidance in performing neuraxial blocks [17,18]. Recently the use of GPS guidance for spinal needle placement was studied by Brinkman et al in human cadavers and attracted much research in this area [19][20][21][22][23][24][25][26][27].…”

Neuraxial blockade is still largely performed as a blind procedure. Despite of developments in the type of needles used and drugs administered, the process of locating the epidural or intra-thecal space is still limited to identification of landmarks by palpation and reliance on tactile feedback of the operator. Ultrasound has provided the long needed "eye" to the procedure and has already shown promise of improving the safety and efficacy or neuraxial blocks. This review focuses on understanding the sonoanatomy of the neuraxial space, performing a systematic pre-procedural ultrasound scan, and reviewing the available evidence.

Real‐time ultrasound‐guided spinal anesthesia using the SonixGPS ultrasound guidance system: a feasibility study

Abstract: The SonixGPS® system simplifies real-time ultrasound-guided spinal anesthesia to a large extent, especially the out-of-plane approach. Nevertheless, it remains a complex multi-step procedure that requires time, specialized equipment, and a working knowledge of spinal sonoanatomy.
