The Influence of Injected Volume on Discomfort During Administration of Digital Block.

Background: Digital nerve block is associated with pain. In a search for methods to reduce the discomfort, we investigated how the volume of anaesthetic fluid influences pain during subcutaneous digital nerve block, and how it affects the success of the anaesthesia.

Methods: A randomized blinded prospective study was performed on 36 healthy volunteers.

The influence of Lidocaine temperature on pain during subcutaneous injection.

Background: Injection of local anaesthetics is an uncomfortable procedure. The purpose of this study was to determine the influence of lidocaine temperature on pain during subcutaneous injection.

Methods: A randomised, double blind trial with 36 healthy volunteers was performed.

The importance of needle gauge for pain during injection of lidocaine.

Background: Local anaesthetics such as lidocaine are used both in minor and major surgical procedures, and can be painful. Different methods have been investigated to reduce the discomfort of the injections. This study investigated if different needle gauges can influence the pain experienced during injection of lidocaine.

The influence of injection speed on pain during injection of local anaesthetic.

Study Objective: To determine the influence of injection speed on pain during injection of local anaesthetics.

Methods: In a blinded randomised study with 36 healthy volunteers, each volunteer received three injections of 4.5 ml lidocaine subcutaneously on the abdomen.

Does adjusting the pH of lidocaine reduce pain during injection?

Background: Receiving local anaestethic injection is painful. A double-blinded randomised study with 32 healthy adult volunteers was performed, with the aim of investigating the effect of buffering lidocaine to reduce the pain during injection.

Methods: Each participant received two subcutaneous injections of 4.
