The sounds of music in the operating room.

BACKGROUND: Little information is available about the effect of music on the operating room (OR) staff. PURPOSE: The objective of this study was to evaluate the perception of the influence of music on physicians and nurses working in the OR. METHODS: A questionnaire was designed and 250 copies were distributed to the doctors and nurses working in the OR at three hospitals. One hundred and seventy-one returned the completed questionnaire and were included in this study. RESULTS: 63% of the participants listen to music on a regular basis in the OR. Classical music is the most requested (58%) and most of the responders do not choose the type of music according to the type of the procedure. In our study, the nurses were more likely to listen to music and the willingness is higher among the female responders. The desired volume is lower as age increases and 78.9% of the participants claimed that music in the OR makes them calmer and more efficient. CONCLUSION: According to our study, music has a positive effect on the staff working in the operating rooms.

Effect of hyperbaric oxygen on survival of composite grafts in rats.

Most treatment with hyperbaric oxygen (HBO) in plastic surgery is for wounds, burns, crush injuries, and infections. We aimed to find out if HBO increases the survival of composite grafts in rats. Twenty Sprague-Dawley rats were randomly assigned to two equal groups (treatment and control). A template 30 x 30 mm was placed on the skin and a composite graft taken from the upper back was harvested and then resutured to the fascia in situ. The treated group was placed in a hyperbaric chamber set at 202 kPa and 100% oxygen for 90 minutes daily for two weeks. Control animals were given no treatment. After death the mean surviving internal surface area of the graft was 372.5 (117.9) mm2 in the control group and 561.3 (85.7) mm2 in the experimental group (p=0.001). Treatment with HBO improved the surviving area of composite grafts in rats, and the beneficial effect was prominent only on the inner surface of the graft.

A side-by-side prospective study of intense pulsed light and Nd:YAG laser treatment for vascular lesions.

Recently, lasers and light systems are used more for the treatment of vascular lesions due to their noninvasiveness, ease of use, and short recovery time. This side-by-side prospective study compares results, satisfaction, and complications after intense pulsed light (IPL) and Nd:Yag laser treatment of small vascular lesions. Twenty-five patients with telangiectases, leg veins, or cherry angiomas underwent treatment of the same category of lesion in the same area. One year after completing treatment, patients were asked to report their satisfaction level after comparing digital photos before and after treatment; 72% felt they had good to excellent results after Nd:Yag treatment, while only 48% felt the same after IPL. The most common side effect after Nd:Yag was hyperpigmentation. Satisfaction level was significantly higher after Nd:Yag than after IPL. Patients with telangiectases, cherry angiomas, or leg veins <1 mm were more satisfied after IPL, while those with leg veins >1 mm were more satisfied after Nd:Yag. Overall, satisfaction with treatment of vascular lesions was greater with Nd:Yag although this method was more painful.

Searching for the favorable donor site for fat injection: in vivo study using the nude mice model.

BACKGROUND: The use of suctioned fat grafts for correction of soft tissue defects is a widespread procedure in esthetic and reconstructive surgery. The main disadvantage of this simple and sensible procedure is the unpredictable absorption rate of the fat graft. A lot of research has been performed aiming for enhancement of the take of the fat grafts. OBJECTIVE: Our study was performed to find if there is any favorable donor site for fat harvesting. METHODS: This in vivo experiment using the nude mice model enables the study of the long-term survival of human fat in an animal model. The fat was harvested from three donor areas: the thigh, abdomen, and breast of a 48-year-old woman who came for an elective esthetic procedure. After centrifugation, 1 cc of fat was injected subcutaneously into the scalp of the nude mouse. There were 15 mice in each of the three groups, according to the selected donor sites. The animals were sacrificed 16 weeks after the procedure. The extracted fat was evaluated in terms of weight, volume, and six histologic parameters: integrity, vascularization, cyst formation, fibrosis, necrosis, and inflammation. RESULTS: This study could not find any statistically significant differences between the three investigated donor sites in the evaluated parameters. CONCLUSION: On the basis of this study, there is no favorable area for harvesting fat grafts. The donor site can be chosen according to the preference of the surgeon and the patient.

Enhancing the take of injected adipose tissue by a simple method for concentrating fat cells.

Injection of aspirated fat for the correction of tissue defects is a common procedure in plastic surgery. The reported rates of fat cell survival vary greatly in the medical literature, and different techniques of harvesting, processing, and reinjecting the fat cells are claimed to be responsible for these differences. However, there is no agreement concerning the best way to process the harvested fat before reinjection. The present study was initiated to examine and evaluate the effect of a simple method of isolating the fat particles on the outcome of fat graft survival. In this study, the nude mouse model was used to examine the survival and take of the fat graft concentrated before injection by the cumbersome recommended closed centrifugation technique in comparison with the authors' recommended open method, using an operating room cotton towel as a platform for concentrating the fat cells and separating them from fluids, oil, and debris. One milliliter of concentrated human fat cells preprocessed by towel separation was injected into the nuchal subcutis of 11 nude mice in the study group, and the same amount of fat that was preprocessed by centrifugation was injected into 11 control mice. Injected fat survived in both groups. No significant differences were found regarding fat graft weight and volume, although a tendency for better survival was noticed in the experimental group. Histologic evaluation of the grafts revealed significantly less fibrosis within the study group, meaning that the quality of the fat grafts was better. The authors found this method to be simple, cheap, and friendly to the surgeon in comparison with traditional processing using the centrifuge.

Long-term fat preservation.

The injection of autologous free fat obtained by suction-assisted lipectomy for the correction of soft tissue defects is a common procedure in plastic surgery. However, unpredictable partial absorption of the injected fat often necessitates repeated harvesting and injection. Fat preservation for future re-injection is indicated to avoid repeated fat harvesting procedures. A previous study has shown that fat obtained by suction can be preserved by freezing for at least 2 weeks. The purpose of the present study was to investigate the effect of freezing autologous free fat for 7 months on the take of the fat graft. Human fat obtained by suction-assisted lipectomy was centrifuged and stored in a domestic refrigerator at -18 degrees C for 7 months. After thawing, the fat was injected into the scalp of 10 nude mice, which served as the study group. In the control group (n = 10), fresh fat was injected. Fifteen weeks later, the fat grafts were dissected out. Volumes, weights, and histological parameters were compared between the groups. The injected fat survived in both the study and the control groups but the histological parameters were significantly inferior in the frozen fat. The weight of the frozen fat was also significantly less compared with the fresh fat. The volume of the frozen fat was inferior but not significantly. Based on this in vivo experiment, it is suggested to refrain from using fat that has been frozen for 7 months or longer. The longest period and the optimal conditions for fat preservation should be further investigated.
