Distraction as a simple and effective method to reduce pain during local anesthesia: A randomized controlled trial.

BACKGROUND: The administration of local anesthetics is considered the most unpleasant part of office-based surgery. Many procedural and pharmacological strategies have been developed to minimize pain. In children and adolescents, distraction has been demonstrated to be an effective way of minimizing pain during local anesthesia. We present a randomized controlled trial of the effect of distraction on pain during local anesthesia in adults. MATERIAL AND METHODS: We have included 115 patients undergoing small office-based surgery to either the face, wrist, or hand. We randomized these patients between two groups: a control group and an intervention group. The intervention group watched a distractive video during the administration of the local anesthetic; for the rest the surgical procedures were performed in an equal fashion in both groups. Preoperative anxiety was scored from 0 to 10 and pain experienced during the injection of local anesthetic was measured on the visual analogue scale of pain (VAS), ranging from 0 to 10. Patient satisfaction was measured on the Patient Satisfaction Questionnaire (PSQ-18), ranging from 18 to 90. RESULTS: Patients had an equal anticipated pain score in control and intervention group. In the intervention group, a reduction of pain scores of 1 point was observed (p = 0.01). There was no difference in patient satisfaction scores between both groups. DISCUSSION: In this study, we demonstrate the pain minimizing effect of distraction during the administration of local anesthesia. Less experienced pain did not result in improved patient satisfaction in our study. We encourage physicians to seek ways to actively distract patients during unpleasant procedures.

[Sunburn of a reconstructed breast: risk of denervated tissue]. / Zonverbranding van een gereconstrueerde borst.

More and more women opt for breast reconstruction with autologous tissue after breast removal. Reconstruction with a deep inferior epigastric perforator (DIEP) flap is the most common technique. In this operation, the nerves of the DIEP flap are cut. This creates a denervated reconstructed breast which is not only numb, but also lacks autonomic response. This makes the tissue more susceptible to thermal injury. We present a case of a 66-year-old woman who underwent uncomplicated breast reconstruction with a DIEP flap 8 months ago. She recently noticed a second-degree burn on her reconstructed breast after she had been sitting in the sun whilst dressed. She did not feel anything and noticed it by accident. Familiarity with this phenomenon is important for all parties involved in care and aftercare of breast cancer and breast reconstruction, so adequate information can be provided. Reinnervation of the reconstructed breast could be a solution, but more research is needed.

[Pyoderma gangrenosum following breast surgery]. / Pyoderma gangrenosum na mammachirurgie.

Pyoderma gangrenosum is a rare, destructive ulcerative condition of the skin. The painful ulcers may occur spontaneously, or result from a minor injury or surgery. The clinical presentation can mimic a necrotizing bacterial infection; however, no micro-organisms can be cultured from the skin lesions and the ulcers fail to respond to antibiotic therapy. Surgical interventions can aggravate the disease process. We describe 2 patients, a 22-year-old woman and a 45-year-old woman, with ulcerative wound abnormalities after breast surgery. After failure of antibiotic therapy and standard wound care, tissue biopsy of the wounds confirmed the clinical diagnosis 'pyoderma gangrenosum'. Wound healing began after systemic steroid treatment. Delays in diagnosis and treatment of pyoderma gangrenosum may result in extensive ulceration and scarring. It is, therefore, important to recognise the characteristic clinical features at an early stage and to start appropriate treatment immediately.
