Paravertebral somatic nerve block for outpatient inguinal herniorrhaphy: an expanded case report of 22 patients.
Inguinal herniorrhaphy is a common outpatient surgical procedure. However, anesthetic techniques for inguinal herniorrhaphy are still associated with numerous side effects. Paravertebral somatic nerve block (PSNB) has the potential advantage to offer unilateral abdominal wall anesthesia and long-lasting pain relief with minimal side effects. We report our initial trial of PSNB for outpatient inguinal herniorrhaphy. ⋯ The results of our initial experience suggest that PSNB is a potentially safe and effective technique. In general, the block provided long-lasting pain relief in most patients with few side effects. A randomized study comparing paravertebral blocks with conventional anesthesia choices is suggested given the findings in this initial series of patients.

Randomized Controlled Trial Clinical TrialThe recovery profile of hyperbaric spinal anesthesia with lidocaine, tetracaine, and bupivacaine.
Surgical procedures previously considered too lengthy for the ambulatory surgery setting are now being performed during spinal anesthesia. The complete recovery profile of tetracaine and bupivacaine are now of interest but are not available in the literature. This study was conducted to compare times to ambulation, voiding, and complete block resolution, as well as the incidence of back and radicular pain, after spinal anesthesia with lidocaine, bupivacaine, and tetracaine. ⋯ Among individual subjects, lidocaine exhibited the shortest recovery profile. However, the recovery profiles of the three anesthetics were very variable between subjects. Time to meeting discharge criteria after bupivacaine or tetracaine was faster in a few subjects than that after lidocaine in other subjects. For ambulatory anesthesia, times to two- and four-segment regression do not accurately predict time to readiness for discharge after spinal anesthesia.
