RESUMEN
OBJECTIVE: Large pressure ulcers are a well know problem occurring frequently on immobilized patients. They can develop rapidly especially over bony prominences on the elderly, ICU patients and on patients after spinal cord injury. Plastic surgical treatment can be challenging if the defects are large and complications occur like affection of anal region or development of a Marjolin's scar ulcer. Large defects of the sacral region are well known in our university hospital. Common local flaps like gluteal rotation or (double) V-Y advancement flap are often used for the treatment of smaller defects. In special cases these therapies are not sufficient. Rarely we use fillet flap of the lower extremity to cover large sacral defects on patients who were unable to walk before. SUBJECTS AND METHOD: In this case report we demonstrate two relatively young paraplegic patients (49 and 57years old) with large sacral defect wounds. One case occurred in 2017, the other in 2019. After spinal cord injury many years ago both of them developed chronic pressure ulcers of the sacral region. In the case of 2017 a Marjolin's scar ulcer developed as a complication. Both patients had previously lost a leg during the surgical treatment. We used the other remaining leg as a fillet flap in combination with interdisciplinary rectum extirpation for sufficient surgical treatment. RESULTS: In both cases adequate coverage of the sacral defect was achieved after interdisciplinary surgical treatment including rectum extirpation. Fillet flaps were safe, even after necessary surgical revisions. In one of the cases a vacuum wound therapy and several debridements were needed. After rehabilitation the patient of the earlier case is able to fully mobilize himself in everyday life and is even able to use public transport. CONCLUSION: Using a fillet flap of the lower extremity to cover large sacral ulcers is often the last possibility of surgical treatment. Though many complications can occur, full rehabilitation and social participation is possible after fillet flap surgery even with loss of both legs. Depending on patient's motivation and availability of orthopedic technology like special electric wheel chairs and other tools full mobility can be achieved.

OBJECTIVE: We assessed the impact of a noise-reduction program in a pediatric operating theatre. BACKGROUND: Adverse effects from noise pollution in theatres have been demonstrated. METHODS: In 156 operations spatially resolved, sound levels were measured before and after a noise-reduction program on the basis of education, rules, and technical devices (Sound Ear). Surgical complications were recorded. The surgeon's biometric (saliva cortisol, electrodermal activity) and behavioral stress responses (questionnaires) were measured and correlated with mission protocols and individual noise sensitivity. RESULTS: Median noise levels in the control group versus the interventional group were reduced by -3 ± 3 dB(A) (63 vs 59 dB(A), P < 0.001) with a grossly decreased number of peaks greater than 70 dB(A) (Δn = -61/hour, P < 0.01). The intervention significantly reduced non-operation-related noise. The incidence of postoperative complications was significantly lower in patients of the intervention group (n = 10/56 vs 20/58 control; P < 0.05). "Responders," surgeons with an above-average noise sensitivity (correlation r = -0.6 for the work subscale of the NoiseQ questionnaire, P < 0.05), experienced improved intrateam communication, a decrease in disturbing conversations and sudden noise peaks (P < 0.05). Biometrically, the intervention decreased both the surgeon's pre- to postoperative rise in cortisol by approximately 20% and the surgeon's electrodermal potentials of greater than 15 µS, indicating severe stress by 60% (P > 0.05). CONCLUSIONS: Spontaneous noise during pediatric operations attains the magnitude of a lawn mower and peaks resemble a passing truck. The sound intensity could be reduced by 50% by specific measures. This reduction was associated with a significantly lowered number of postoperative complications. The surgeon's benefits are idiosyncratic with "responders" experiencing marked improvements.
