Assessment of computer-controlled local anesthetic delivery system for pain control during restorative procedures: A randomized controlled trial.

ABSTRACT: Background. . Local anesthesia is given to decrease pain perception during dental treatments, but it may itself be a reason for pain and aggravate the dental fear. Computer-controlled local anesthetic delivery system (CCLADS) is one of the alternatives for decreasing the patients' pain during local anesthesia. This study compared the time required for the recovery from anesthesia, pain/discomfort during injection and pain/discomfort 24 hours after administering local anesthesia with CCLADS, a standard self-aspirating syringe and a conventional disposable 2-mL syringe. Methods. The study was conducted on 90 subjects (an age group of 20-40 years), who suffered from sensitivity during cavity preparation. They were randomly divided into three groups of 30 individuals each to receive intraligamentary anesthesia (2% lignocaine with 1:80,000 adrenaline) using either of the three techniques: CCLADS, a standard self-aspirating syringe, or a conventional disposable 2-mL syringe. The onset of anesthesia, time required for recovery from anesthesia (in minutes), pain/discomfort during injection and pain/discomfort 24 hours after administering local anesthesia were recorded. Results. The time required for the onset of anesthesia and recovery from anesthesia was shorter with CCLADS (4.83±2.31 and 34.2±1.895, respectively) as compared to the standard self-aspirating group (10.83±1.90 and 43.5±7.581, respectively) and the conventional group (11.00±2.03 and 43.5±6.453, respectively) (P<0.001). The patients in the CCLADS group experienced no pain during local anesthesia administration as compared to the patients in the self-aspirating and conventional groups. The CCLADS and self-aspirating groups showed lower pain response as compared to the conventional group for pain after 24 hours. Conclusion. CCLADS can be an effective and pain-free alternative to conventional local anesthetic procedures.

Project description:BackgroundThe use of sedation during interventional procedures has continued to rise resulting in increased costs, complications and reduced validity during diagnostic injections, prompting a search for alternatives. Virtual reality (VR) has been shown to reduce pain and anxiety during painful procedures, but no studies have compared it to a control and active comparator for a pain-alleviating procedure. The main objective of this study was to determine whether VR reduces procedure-related pain and other outcomes for epidural steroid injections (ESI).MethodsA randomized controlled trial was conducted in 146 patients undergoing an ESI at 6 hospitals in Thailand and the United States. Patients were allocated to receive immersive VR with local anesthetic, sedation with midazolam and fentanyl plus local anesthetic, or local anesthetic alone. The primary outcome was procedure-related pain recorded on a 0-10 scale. Other immediate-term outcome measures were pain from a standardized subcutaneous skin wheal, procedure-related anxiety, ability to communicate, satisfaction, and time to discharge. Intermediate-term outcome measures at 4 weeks included back and leg pain scores, function, and success defined as a ≥2-point decrease in average leg pain coupled with a score ≥5/7 on a Patient Global Impression of Change scale.FindingsProcedure-related pain scores with both VR (mean 3.7 (SD 2.5)) and sedation (mean 3.2 (SD 3.0)) were lower compared to control (mean 5.2 (SD 3.1); mean differences -1.5 (-2.7, -0.4) and -2.1 (-3.3, -0.9), respectively), but VR and sedation scores did not significantly differ (mean difference 0.5 (-0.6, 1.7)). Among secondary outcomes, communication was decreased in the sedation group (mean 3.7 (SD 0.9)) compared to the VR group (mean 4.1 (SD 0.5); mean difference 0.4 (0.1, 0.6)), but neither VR nor sedation was different than control. The trends favoring sedation and VR over control for procedure-related anxiety and satisfaction were not statistically significant. Post-procedural recovery time was longer for the sedation group compared to both VR and control groups. There were no meaningful intermediate-term differences between groups except that medication reduction was lowest in the control group.InterpretationVR provides comparable benefit to sedation for procedure-related pain, anxiety and satisfaction, but with fewer side effects, superior communication and a shorter recovery period.FundingFunded in part by grants from MIRROR, Uniformed Services University of the Health Sciences, U.S. Dept. of Defense, grant # HU00011920011.
