Randomized Controlled Trial Comparative Study Clinical TrialHospital discharge after ambulatory knee arthroscopy: A comparison of epidural 2-chloroprocaine versus lidocaine.
This prospective, randomized, double-blind study compares the efficacy of epidural 2-chloroprocaine and lidocaine for attaining hospital discharge criteria after ambulatory knee arthroscopy. We hypothesized that 2-chloroprocaine would facilitate earlier discharge than lidocaine. ⋯ Epidural 3% 2-chloroprocaine without epinephrine is an advantageous choice for ambulatory knee arthroscopy. It enables readiness for discharge an hour sooner than 1.5% lidocaine, requires fewer reinjection interventions, and may reduce delayed discharge secondary to prolonged time to void. This clinical study shows the superiority of epidural 3% 2-chloroprocaine over 1.5% lidocaine for expediting hospital discharge after ambulatory surgery.

Randomized Controlled Trial Comparative Study Clinical TrialSelective ulnar nerve localization is not essential for axillary brachial plexus block using a multiple nerve stimulation technique.
The multiple-injection technique for axillary block, in which the 4 distal nerves of the plexus are located by a nerve stimulator and separately injected, has been shown to produce a rapid onset and a high success rate. However, this technique may be more difficult and time consuming than other axillary block methods. A simplified multiple-nerve stimulation technique, in which the ulnar nerve was not located, was compared in the present double-blind study to the 4-injection approach. ⋯ A triple-injection method of axillary block in which the ulnar nerve was not purposely located provides a spread and a latency of sensory block equal to that obtained with a 4-injection technique. A shorter performance time is an advantage of this approach.

Randomized Controlled Trial Clinical TrialSpinal anesthesia with hypobaric bupivacaine for knee arthroscopies: effect of posture on motor block.
The clinical impact of patient positioning on motor block during unilateral spinal anesthesia was the focus of our study. It was assumed that a 45 degrees rotation toward the prone position would minimize blocking the ventral motor roots compared with using the conventional lateral decubitus position. ⋯ The position of the patient affects the spread of the spinal anesthesia when clearly hypobaric agents are used. However, this small modification in positioning of the patient did not lead to a clinically meaningful difference in the spread of the motor block.

Comparative StudyAn observational study of the frequency and pattern of use of epidural steroid injection in 25,479 patients with spinal and radicular pain.
Frequency of epidural steroid injections (ESI) and characteristics of patients receiving them are unknown or poorly described. Patients believed to respond better to ESI include young or middle-aged individuals, those with recent onset or a radicular pattern of pain, and patients without previous spinal surgery. The aim of this study is to estimate the frequency of ESI, to examine the characteristics of patients who have them recommended, and to determine if clinical practice reflects published data pertaining to indications for ESI. ⋯ ESI are commonly used to treat patients with spinal and radicular pain. There is some consistency between clinical practice and published recommendations for ESI use.

Case ReportsAxillary brachial plexus block with patient controlled analgesia for complex regional pain syndrome type I: a case report.
Brachial plexus block (BPB) has been cited as a treatment modality for complex regional pain syndrome type I (CRPS I) of the upper limb. However, there are no reports using axillary BPB with patient controlled analgesia (PCA) for the treatment of CRPS I. This report is based on the retrospective observations of the outcome and effects of axillary BPB with PCA in a patient with CRPS I. ⋯ Axillary BPB with PCA may provide patients with CRPS I of the upper limb a feasible and effective treatment. .
