Comparison of 1% chloroprocaine hydrochloride versus hyperbaric bupivacaine spinal in patients undergoing anorectal surgery in an ambulatory surgery center: a double-blind randomized clinical trial.
Preservative-free chloroprocaine is a promising spinal anesthetic for ambulatory surgeries, offering a short duration of action and minimal side effects, which promote faster recovery and discharge. Thus, this study aimed to compare chloroprocaine hydrochloride to the widely used bupivacaine as a spinal anesthetic in ambulatory anorectal surgeries. We hypothesized that chloroprocaine will lead to quicker recovery and discharge, supporting its use in the ambulatory surgical setting. ⋯ Our study demonstrated a significantly reduced time to meeting discharge criteria with chloroprocaine compared with bupivacaine without an increased risk of TNS. Our results support the use of chloroprocaine for spinal anesthesia in ambulatory anorectal surgeries.

Mapping axillary sensory cutaneous nerves for enhanced analgesic approaches in axillary surgery: a cadaveric study.
Innervation of the breast includes branches of thoracic intercostal nerves, the superficial cervical plexus, the brachial plexus, and the intercostobrachial nerve (ICBN). Commonly used blocks for breast surgery provide incomplete analgesia of the axillary region. This cadaveric study aims to identify and map the axillary sensory cutaneous nerves. ⋯ In addition to the ICBN, two branches of the brachial plexus were identified entering axillary subcutaneous tissue. These branches are not currently considered when providing analgesia for breast surgery and may contribute to pain following surgery that involves axillary dissection.

Timing of intravenous dexamethasone and analgesia after brachial plexus block: a randomized, double-blind, placebo-controlled trial.
The addition of intravenous dexamethasone can significantly prolong analgesia and reduce opioid-related side effects after brachial plexus blockade, but the most effective administration time is yet unknown. The objective of this study is to determine if the timing of administration of dexamethasone affects the duration of analgesia after supraclavicular brachial plexus block. ⋯ Our results suggest that perioperative administration of 8 mg of intravenous dexamethasone (from 1 hour prior and up to 2 hours postblock) provides similar duration of analgesia to administration at the time of brachial plexus block.
