Does Spinal Block Through Tattooed Skin Cause Histological Changes in Nervous Tissue and Meninges?: An Experimental Model in Rabbits.
Although there is no documented evidence that tattoo pigments can cause neurological complications, the implications of performing neuraxial anesthesia through tattooed skin are unknown. In this study, we aimed to assess whether spinal puncture performed through tattooed skin of rabbits determines changes over the spinal cord and meninges. In addition, we sought to evaluate the presence of ink fragments entrapped in spinal needles. ⋯ On the basis of the present results, intrathecal injection of saline through a needle inserted through tattooed skin is capable of producing histological changes over the meninges of rabbits. Ink fragments were entrapped inside the spinal needles, despite the presence of a stylet.

Review Meta AnalysisThe Effects of Perioperative Regional Anesthesia and Analgesia on Cancer Recurrence and Survival After Oncology Surgery: A Systematic Review and Meta-Analysis.
Potentially, perioperative regional anesthesia and analgesia (RA) could influence the outcomes of patients with cancer. The aim of this systematic review and meta-analysis was to evaluate the effects of perioperative RA on survival and cancer recurrence after oncologic surgery. ⋯ Our meta-analysis suggests that RA may improve overall survival but not reduce cancer recurrence after oncologic surgery.

ReviewNeurological Complications Related to Elective Orthopedic Surgery: Part 3: Common Foot and Ankle Procedures.
Part III of a review series on neurological complications of orthopedic surgery, this article describes the mechanisms and likelihood of peripheral nerve injury associated with some of the most common elective foot and ankle procedures for which anesthesiologists may administer regional anesthesia. Relevant information is broadly organized according to type of surgical procedure to facilitate reference by anesthesiologists and members of the anesthesia care team.

Randomized Controlled Trial Comparative StudyEffects of Preoperative Serotonin-Receptor-Antagonist Administration in Spinal Anesthesia-Induced Hypotension: A Randomized, Double-blind Comparison Study of Ramosetron and Ondansetron.
The adverse effects of spinal anesthesia (SA) include arterial hypotension and bradycardia. The aim of this study was to compare the effects of 2 type 3 serotonin receptor antagonists in SA-induced adverse effects. Specifically, we assessed whether ramosetron was more effective than ondansetron in reducing SA-induced decreases in blood pressure (BP) and heart rate (HR). ⋯ The administration of ramosetron (0.3 mg) significantly attenuated the SA-induced decrease in BP compared with 4 or 8 mg of ondansetron and HR compared with 4 mg of ondansetron.

ReviewNeurological Complications Related to Elective Orthopedic Surgery: Part 1: Common Shoulder and Elbow Procedures.
Many anesthesiologists are unfamiliar with the rate of surgical neurological complications of the shoulder and elbow procedures for which they provide local anesthetic-based anesthesia and/or analgesia. Part 1 of this narrative review series on neurological complications of elective orthopedic surgery describes the mechanisms and likelihood of peripheral nerve injury associated with some of the most common shoulder and elbow procedures, including open and arthroscopic shoulder procedures, elbow arthroscopy, and total shoulder and elbow replacement. Despite the many articles available, the overall number of studied patients is relatively low. Large prospective trials are required to establish the true incidence of neurological complications following elective shoulder and elbow surgery.
