Randomized Controlled Trial Multicenter Study
Safety and Efficacy of Needle-Free Powder Lidocaine Delivery System in Adult Patients Undergoing Venipuncture or Peripheral Venous Cannulation: Randomized, Double-blind, Placebo-controlled Trial.
The purpose of this study was to evaluate the efficacy, safety, and tolerability of a needle-free powder lidocaine delivery system compared with sham placebo in adults. ⋯ This clinical trial demonstrated that use of a needle-free powder lidocaine delivery system resulted in a significant reduction of pain during venipuncture and peripheral intravenous cannulation in adults. Both the predefined primary endpoint and all 3 secondary endpoints were met. The needle-free powder lidocaine delivery system may be an option for analgesia during venous access procedures in adults.

Randomized Controlled Trial Multicenter Study Comparative Study
Comparison of intra-articular bupivacaine-morphine with bupivacaine-tenoxicam combinations on post-operative analgesia in patients with arthroscopic meniscectomy: a prospective, randomised study.
There are many alternatives for post-operative pain relief in patients who have had general anaesthesia. The aim of this study was to evaluate the efficacy of intra-articular bupivacaine + morphine and bupivacaine + tenoxicam applications in post-operative pain control in patients undergoing knee arthroscopy with general anaesthesia. ⋯ level 1, therapeutic, randomised, multicentric study.

Multicenter Study Controlled Clinical Trial
The Effects of Local Anesthesia Administration on Pain Experience During Interventional Spine Procedures: A Prospective Controlled Trial.
It has been postulated that local anesthetic administration may be the most painful part of interventional spine procedures. Despite this, there is a lack of evidence supporting the commonly used traditional technique of anesthetic delivery as part of these procedures. This study tested three hypotheses: 1) alternative method of local anesthesia injection is superior to the traditional method; 2) using the traditional method of injection is not superior to using no local anesthetic; and 3) treatment needle size, anesthetic injection technique, and sedation are associated with pain experienced during procedures. ⋯ The alternative method was superior (P < 0.05) to the traditional method on post procedural pain scores. Injecting local anesthetic with the traditional or alternative method was not superior to using no local anesthetic. Treatment needle size, pain at one inch of treatment needle insertion, and baseline pain were all significantly (P < 0.05) associated with overall procedural pain. Further studies are needed optimize and justify local anesthetic injections for these procedures.

Randomized Controlled Trial Multicenter StudyA Multicenter Evaluation of a Closed-Loop Anesthesia Delivery System: A Randomized Controlled Trial.
Closed-loop systems for anesthesia delivery have been shown to outperform traditional manual control in different clinical settings. The present trial was aimed at evaluating the feasibility and efficacy of Bispectral Index (BIS)-guided closed-loop anesthesia delivery system (CLADS) in comparison with manual control across multiple centers in India. ⋯ Our study in a multicenter setting proves the consistently better performance of automated anesthesia drug delivery compared with conventional manual control. This highlights an important advantage of an automated system for delivering standardized anesthesia, thereby overcoming differences in practices among anesthesiologists.

Randomized Controlled Trial Multicenter Study Comparative StudyUltrasound-Guided Single-Injection Infraclavicular Block Versus Ultrasound-Guided Double-Injection Axillary Block: A Noninferiority Randomized Controlled Trial.
Single-injection ultrasound-guided infraclavicular block is a simple, reliable, and effective technique. A simplified double-injection ultrasound-guided axillary block technique with a high success rate recently has been described. It has the advantage of being performed in a superficial and compressible location, with a potentially improved safety profile. However, its effectiveness in comparison with single-injection infraclavicular block has not been established. We hypothesized that the double-injection ultrasound-guided axillary block would show rates of complete sensory block at 30 minutes noninferior to the single-injection ultrasound-guided infraclavicular block. ⋯ We failed to demonstrate that the rate of complete sensory block of the double-injection axillary block is noninferior to the single-injection infraclavicular block. However, the rate of complete sensory block at 30 minutes is statistically significantly lower with the axillary block. The ultrasound-guided single-injection infraclavicular block thus seems to be the preferred technique over the axillary for upper arm anesthesia.
