Current fashion in body art includes low back tattoos of varying designs and colors, a trend that presents unique concerns for anesthesia providers. Does the placement of epidural catheters risk the introduction of tattoo pigment dyes into the epidural space through the process of coring? Are there specific risks associated with tattoo dyes and epidural needle placement? We performed a comprehensive review of the literature using multiple search databases with the intent to form guidelines for practice using a level of evidence taxonomy. ⋯ Continued investigation is necessary before comprehensive practice guidelines regarding the practice of placing epidural needles and catheters through lumbar tattoos can be developed. We suggest avoidance of piercing tattoos when performing epidural punctures until there is sound evidence of short-term and long-term safety.

Comparative Study
Patient outcomes comparing CRNA-administered peripheral nerve blocks and general anesthetics: a retrospective chart review in a US Army same-day surgery center.
We compared outcomes between patients receiving general anesthesia (GA) vs regional block (RB) in a military same-day surgery unit (SDSU), where Certified Registered Nurse Anesthetists (CRNAs) delivered all RBs and GA. All patient charts from 2003 through 2006 were reviewed. Patients were included if they were 18 years or older, had an ASA physical status I or II, and underwent a shoulder or knee arthroscopy that used either RB or GA. ⋯ The GA group received more morphine equivalents of narcotic in the operating room (22.9 vs 15.1 mg, P < .001) yet still had higher pain scores postoperatively than the RB group (1.1 vs 0.3, P < .001). The GA group received a significantly greater number of antiemetic doses intraoperatively (0.58 vs 0.04, P < .001) but still had a higher, although nonsignificant, rate of emesis (15.5% vs 10.0%). Patients receiving RB had less pain and received less analgesia without any increase in postoperative nausea and vomiting, hospital time, or anesthesia-related complications.

Familial hyperkalemic periodic paralysis (HYPP) is a rare genetic disorder in which the sodium channels in skeletal muscle cells have altered structure and function. Small elevations in serum potassium lead to inactivation of sodium channels, causing episodic weakness or paralysis. Exposure to cold, anesthesia, fasting, emotional stress, potassium ingestion, and rest after exercise can stimulate an attack. ⋯ Careful attention was given to monitoring and maintenance of core temperature, use of insulin and glucose to maintain normokalemia, and carbohydrate loading the night before surgery. The patient recovered from the anesthetic without complication and had pain relief for approximately 22 hours postoperatively because of the femoral nerve block. The patient was without weakness or paralysis related to HYPP in the postanesthesia care unit or throughout his hospitalization.

Randomized Controlled Trial
Effects of guided imagery on postoperative outcomes in patients undergoing same-day surgical procedures: a randomized, single-blind study.
The purpose of this investigation was to evaluate the effects of guided imagery on postoperative outcomes in patients undergoing same-day surgical procedures. Forty-four adults scheduled for head and neck procedures were randomly assigned into 2 groups for this single-blind investigation. Anxiety and baseline pain levels were documented preoperatively. ⋯ At 2 hours, the guided imagery group reported significantly less pain (P = .041). In addition, length of stay in PACU in the guided imagery group was an average of 9 minutes less than in the control group (P = .055). The use of guided imagery in the ambulatory surgery setting can significantly reduce preoperative anxiety, which can result in less postoperative pain and earlier PACU discharge times.

This study was designed to identify the systolic blood pressure (SBP) and mean arterial pressure (MAP) at which rebleeding occurs when a clot is formed by a hemostatic agent, Celox or TraumaDEX, compared with a standard dressing. Fifteen pigs (5 each) were assigned randomly to 1 of 3 groups: Celox, TraumaDEX, or standard pressure dressing as a control. In all animals, the femoral artery and vein were transected to simulate traumatic injury. ⋯ There were statistically significant differences between Celox (mean SBP, 166.4 mm Hg; mean MAP, 1376 mm Hg) and the control (mean SBP, 88.25 mm Hg; mean MAP, 59.7 mm Hg), and between TraumaDEX (mean SBP, 152.2 mm Hg; mean MAP, 113.2 mm Hg) and the control (P < .05). However, no statistically significant difference existed between Celox and TraumaDEX. Celox and TraumaDEX effectively prevent rebleeding compared with standard dressing.
