Summary

Local anesthesia-related pain is associated with injection speed. An electronic constant-speed injector was developed for slow and steady injection to alleviate dermatological anesthesia pain. The investigators aimed to validate the efficacy of an electronic constant-speed injector in reducing pain during local infiltrative anesthesia by comparing it to the conventional manual injection method. Patients who underwent local infiltrative anesthesia in an area \>5 cm during scalp surgery were selected. Each side of the surgical field was randomly assigned a manual or electronic injector for local infiltration. Each participant used the numeric rating scale (NRS) to rate infiltration-related pain on each side.

DEVICE

Electronic injector

At room temperature, 1% lidocaine combined with 1:100,000 epinephrine was used as a local anesthesia. The electronic constant-speed injector, i-JECT® (MediHub Inc., Gyeonggi-do, Korea) (Figure 1) was used, and the injection speed of the injector was set at level 1 (0.25 mL/s) or level 2 (0.4 mL/s). The injection site in a patient was divided into two sides (left and right). The method of local infiltration (manual or using the electronic injector) was randomly assigned to each side of the surgical field, and 2.5 cc (0.5 cc at five separate areas) of local anesthetic was injected individually using a 5 cc syringe with a 31-gauge needle. All injections were administered by a single surgeon (Sung Joo Tommy Hwang) to reduce inter-operator variation.
