OBJECTIVE To test the hypothesis that subcutaneous wound oxygen tension (PsqO2) has a predictive relation to the development of wound infection in surgical patients. DESIGN A noninterventional, prospective study. SETTING A university department of surgery. PATIENTS One hundred thirty operative general surgical patients at notable risk of infection as(More)
Complications and outcomes were monitored following the implantation of 1655 breast implants over a 15-year period. Smooth, polyurethane, and textured implants were used in a variety of clinical settings. The time course of capsular contracture was analyzed by the Kaplan-Meier method. Regardless of implant type or indication for surgery, the probability of(More)
Oxygen tension and collagen deposition were measured in standardized, subcutaneous wounds in 33 postoperative surgical patients. Pertinent clinical and wound parameters were analyzed by Pearson's correlation test and sequential linear regression analysis. Collagen deposition was directly and significantly proportional to wound oxygen tension and measures of(More)
BACKGROUND Breast implants have been used worldwide for more than 40 years. Despite extensive clinical experience, there is continued concern about the safety of these devices. The purpose of this study was to compare the efficacy, complication rates, frequency of reoperation, and degree of patient satisfaction with different types of implants. METHODS(More)
Subcutaneous tissue oxygen tension was measured as an index of perfusion in 44 postoperative patients. Hypoperfusion was defined as suboptimal tissue oxygen tension unresponsive to increased inspired oxygen but becoming responsive after increased fluid infusion. Twelve of thirty patients who underwent major abdominal and flank operations were found to be(More)
The safety and practicality of nipple-sparing mastectomy (NSM) are controversial. Review of a large breast center’s experience identified 99 women who underwent intended NSM with subareolar biopsy and breast reconstruction for primary breast cancer. Outcome was assessed by biopsy status, postoperative nipple necrosis or removal, cancer recurrence, and(More)
Breast conservation therapy, consisting of lumpectomy, axillary node dissection, whole-breast irradiation, and a boost to the tumor bed, is an increasingly popular option for the treatment of breast cancer. Among patients with stage I and stage II disease, breast conservation therapy yields survival rates equivalent to those for mastectomy. The cosmetic(More)
Smooth-walled silicone implants have been widely used in breast surgery. Capsular contracture, causing undesirable firmness and spherical deformity, has been a common problem. Recent studies suggest that polyurethane-covered breast implants are associated with a lower incidence of capsular contracture. The statistical methodology employed in some of these(More)
Eighty-five patients with augmentation mammaplasty were surveyed. Patients were polled about knowledge of risks, level of concern, awareness of media publicity, incidence of complications, and degree of satisfaction with breast implants. Sixty-one percent of the patients were satisfied or very satisfied with implants, whereas 32% were somewhat or very(More)
