Lumbar tattoos, magnetic resonance imaging, and obstetric anesthesia: what do they have in common?

Tattoo complications and magnetic resonance imaging: a comprehensive review of the literature

Tattooed patients undergoing magnetic resonance imaging (MRI) can develop cutaneous complications during the procedure. Our aim was to review all published case reports on MRI-induced tattoo complications to identify a possible pattern. So far, 17 cases have been reported. Five (29%) of the cases were in cosmetic tattoos. Symptoms are abrupt and painful with fast onset during MRI, sometimes requiring termination of the procedure. Clinical signs are absent or manifested as inflammation sensed as burning. No thermal skin burns have been recognized. Full recovery is fast, with no sequelae. MRI-induced tattoo complications are uncommon. Patients with cosmetic and traditional tattoos can undergo routine MRI.

Tattoo and epidural analgesia: Rise and fall of a myth

Since 2002, it has been unclear whether epidural analgesia (EA) could safe through a lower back tattoo. Theoretical risks of pigment tissue coring have led to precautionary measures and misconception that EA should be excluded. We reviewed chronologically the 18 years of medical literature summarizing the so-called risks of EA through lower back tattoo in parturient women. To date, no convincing complication has been ever reported after an EA through a tattoo. We hope this review will bring a closure to a 18-year-old "non-issue" that has poisoned and stressed unnecessarily a generation of parturient.

Tattooing and various piercing: anaesthetic considerations

PURPOSE OF REVIEW

Body art is increasing since the 1990s. Anaesthesiologists would be more and more confronted to patient with tattooing or piercing, or both. This review discusses the anaesthetic potential risks and complications observed with tattooing and piercing, their management and prevention.

RECENT FINDINGS

Airway management during anaesthesia is of particular interest with oral jewelry. Patients often refuse to remove their piercing for fear of tract closure. There are no serious complications reported after epidural puncture through a tattoo, although any long-term consequence cannot be discarded yet. Even theoretical concerns are more and more debated.

SUMMARY

Oral and nasal piercing is of particular concern because of the risks of swallowing and aspiration. Consequently, patients should be advised to remove piercing before anaesthesia. Emergency situations are especially risky and anaesthesiologists should be aware of the piercing removal techniques. In case of piercing loss, radiographies and fiberoptic endoscopy of the upper airways and digestive tracts should be performed to eliminate aspiration or swallowing of the foreign body. Epidurals should not be denied to parturients with lumbar tattooing. However, it seems still prudent to avoid direct tattoo puncture or when unavoidable, to nick the skin prior to inserting the needle through the tattoo.
