The learning process of the hydrolocalization technique performed during ultrasound‐guided regional anesthesia

Abstract

The Hloc performed during the OOP approach of ultrasound-guided regional anesthesia is a simple technique with a relatively short learning process feasible for efficient placement of ABs.

A Scoping Review of the Evidence for Teaching Ultrasound-Guided Regional Anesthesia

“…49 Showing indirectly where the tip of the needle is may be demonstrated safely using a hydrolocalization technique resulting in the performance of a high rate of successful blocks. 16 This is an example of visuospatial skill and supports the assertion that good visuospatial skills correlate with good UGRA performance. 21 This correlates with work in the surgical field.…”

“…9 A formal structured UGRA training program is described as the optimum way to provide "the coexistence of an appropriate patient, trainee, trainer, and environment." 8 Motor Skills [12][13][14][15][16][17][18][19][20][21][22][23][24][25][26] There is an increasing evidence base 14,20 for simulation using low-or high-fidelity models to decrease the time taken to attain proficiency. Discovery learning occurs at a variable rate, 15 but expert formative feedback 12 shortens the learning curve to an average of 10 procedures (with less complex UGRA blocks).…”

“…Acquisition of motor skills also occurs at a variable rate, 15,17 but visuospatial skills seem to be a better predictor of good performance compared with hand-eye motor skills. 21 Early literature emphasized needle-tip demonstration by the novice 13 or awareness of the tip location 16 to ensure the avoidance of critical errors.…”

Dominant hand operating probe vs needle: a comparison study of ultrasound‐guided needle placement in phantom models

“…While the learning curve for simulated ultrasound‐guided interventional tasks by novices is short, errors are common, especially in first attempts (2–3 per block attempt) . Errors and prolonged and multiple attempts at needle placement may reduce trainees' confidence and impede the learning process.…”

“…[6] Hidrolokalizasyon ile iğne ucundan itibaren oluşan sıvı hareketi ve sıvı konsolidasyonunun farklı USG görüntüsünden yararlanılır. Hidrolokalizasyon bir mekanik birikim yarattığı için olgumuzda arter çevresinde görülen sinir paketine ulaşmak için veni arterden uzaklaştırma yöntemi olarak yararlanılmıştır.…”
