'Common sense and a thick hide'. Physicians providing care to their own family members.
OBJECTIVE: To determine how frequently physicians treat their relatives in 17 categories of care, their reasons for deciding to treat, and their level of comfort with this practice. DESIGN: Mailed survey. SETTING: Rural, suburban, and urban practices in Oregon. SUBJECTS: Two thousand fourteen physicians in the following specialties: general practice, family practice, general internal medicine, general surgery, orthopedic surgery, obstetrics/gynecology, and pediatric medicine. RESULTS: One thousand two hundred ninety-two questionnaires (64%) were returned. Minor prescribing was done most frequently, followed by routine pediatric care, physical examinations, and minor surgery. All other forms of care occurred rarely, and there appears to be a gradient based on the level of complexity, seriousness, and potential for conflict with privacy. In general, older, male, and rural physicians provided more services to family members than their younger, female, and urban counterparts. General and family practitioners performed the most family care; general internists, the least. The most important reasons for providing care were convenience for the patient and request from relatives. Providers were most comfortable providing care to their children and least comfortable providing care to their grandparents. CONCLUSIONS: There is a wide range of practice, depending on the nature of the care and provider characteristics. Physicians report treating their own family members rarely and face significant dilemmas when doing so.
Low conductivity irrigating solutions for arthroscopy.
The purpose of this study was to find a nonconductive physiologic solution to use for arthroscopy when electrosurgery is performed. We studied the effect of several solutions on proteoglycan synthesis in bovine articular cartilage slices, and the effect of using an electrosurgical instrument in various solutions in bovine knee joints. Both HEPES buffer 0.3 M (N-2-hydroxyethylpiperazine-N'-2-ethanesulfonic acid) (Sigma Chemical Company, St. Louis, Missouri) and glycerol 2.6% gave good results in both categories. The glycerol solution appears to be the best from those tested since it supported cartilage metabolism somewhat better and is far less expensive than HEPES solution. Thus, in the use of electrosurgery during arthroscopic procedures, solutions such as Ringer's lactate and saline are too conductive to be effective or safe. Distilled water is nonphysiologic. Glycerol 2.6% is safe and effective and supports articular cartilage metabolism reasonably well for up to 2 h.
