Double-dorsal Versus Single-volar Digital Block

Not Applicable

Completed

• Conditions: Anesthesia, Local; Nerve Block; Pain; Laceration of Skin
• Interventions: Procedure: Dorsal digital block; Procedure: Palmar digital block

• Registration Number: NCT06274073
• Lead Sponsor: Ankara City Hospital Bilkent

Brief Summary

The aim of this study is to compare the traditional dorsal double injection digital block with the palmar single injection technique in the suturing of acute traumatic hand finger lacerations in terms of injection pain score (NRS), anesthesia onset time, and success of anesthesia.

It is understood that single injection digital block and double injection digital block techniques do not have significant advantages over each other in terms of pain levels and procedure times.

However, the need for rescue anesthesia was evaluated to be lower in the single injection digital block technique. This difference is especially due to measurements in the volar region incisions.

According to the results of this study, we think that choosing the single injection digital block technique for volar region incisions is a more rational approach, especially in terms of the data of the need for rescue anesthesia.

Arm && Interventions

Group	Intervention	Description
Double injection dorsal digital block	Dorsal digital block	The needle was inserted into the proximal dorsal root of the proximal phalanx, into both the medial and lateral parts, perpendicular to the fingers and the frontal plane. After the aspiration, the injection was performed slowly and the needle was withdrawn concurently. A total of 3 ml of anesthetic agent (prilocaine hydrochloride) was injected into both the medial and lateral parts of the finger, 1.5 ml for each side.
Single injection palmar digital block	Palmar digital block	The needle was inserted into the subcutaneous region from the palmar side to the root of the proximal phalanx, perpendicular to the frontal plane and the finger. For anesthesia, 3 ml of anesthetic agent (prilocaine hydrochloride) was applied to the described point with this single injection and the needle was slowly removed.

Primary Outcome Measures

Name	Time	Method
Anesthesia pain score	3rd minute	Numerical rating scale (NRS): 0 to 10 (min-max); higher scores indicates more pain

Secondary Outcome Measures

Name	Time	Method
Anesthesia onset time	Measurements are provided per 30 seconds (30-60-90-120 seconds and more if necessary)	Time achieved to total anesthesia
