Resident doctors still work too long: report


(Reuters) - First-year residents may soon get a reprieve from grueling hospital shifts that last more than 24 hours, but that is not enough to prevent an alarming number of medical errors, according to a report released on Friday.
Starting July 1, new rules will require first-year residents to work shifts no longer than 16 straight hours. But that will not spare more experienced residents from working as long as 28 hours at a stretch.
A group of 26 doctors and patient safety experts are calling for limiting all resident physician work to shifts of 12 to 16 hours. Their report was published on Friday in the journal Nature & Science of Sleep journal.
"What started as a good system has evolved into a system where the residents are extremely sleep deprived, caring for some of the sickest patients in the country, and that's a set-up for disaster," Dr. Christopher Landrigan, one of the report's authors, said in an interview.
The report is the product of a conference held last year at Harvard Medical School. It also recommends that residents should be subject to increased supervision by attending physicians and hand off routine work like blood draws or paperwork to other staff.
The group cited U.S. government statistics that show as many as 180,000 patients each year die due to harm resulting from their medical care.
The new resident work rules are based on recommendations from the Institute of Medicine, which estimated implementation would cost $1.7 billion, mostly to hire additional hospital staff. Landrigan said the costs would be offset by reducing medical errors.
"Few people enter a hospital expecting that their care and safety are in the hands of someone who has been working a double-shift or more with no sleep," said Dr. Lucian Leape, adjunct professor of health policy at the Harvard School of Public Health and a co-author of the report.
"If they knew, and had a choice, the overwhelming majority would demand another doctor or leave," he said in a statement.
The Accreditation Council for Graduate Medical Education (ACGME), the body that oversees residency training, issued the new rules for first-years in September 2010. It has said it was committed to examining resident hours "with a goal of making them better."
Landrigan said he does not expect the report to change the rules for other residents anytime soon, because of tradition and costs.

Manejo de la hiponatremia: proveyendo tratamiento y evitando daño


Manejo de la hiponatremia: proveyendo tratamiento y evitando daño
Management of hyponatremia: providing treatment and avoiding harm.

Cleve Clin J Med. 2010 Oct;77(10):715-26.
Abstract
Hyponatremia, in its most severe form, requires urgent infusion of hypertonic saline to correct cerebral edema. However, overly rapid correction of chronic hyponatremia can cause osmotic demyelination syndrome. The authors review the treatment of hyponatremia in order to provide clinicians with a sound approach in a variety of settings in which severity, symptoms, and underlying disease states influence therapy. Also discussed is the current role of vasopressin antagonists in treatment.

Abstract
CONTEXT: Fluid absorption is inevitable complication of transuretheral resection of prostate and serum electrolytes changes can indirectly assess the irrigation fluid absorption. AIMS: To monitor the extent of 1.5% glycineirrigation fluid absorption during transurethral resection of prostate (TURP), by measuring the changes of serum sodium and potassium levels peri-operatively. SETTINGS AND DESIGN: This is a randomized prospective cohort observational study. MATERIALS AND METHODS: The 86 male patients of ASA grades I to III in the age group of 50 to 80 years, scheduled for elective TURP surgery under central neuraxial block, were studied. Their preoperative and post-operative serum sodium, potassium and calcium levels were measured. When duration of surgery exceeds 60 min, serum sodium and potassium levels were done intra-operatively with venous blood samples by using blood gas analyser. The height of irrigation fluid column was kept constant at 60 cm. These changes were correlated with the volume of irrigating fluid used, duration of procedure and the volume of prostate gland resected. STATISTICAL ANALYSIS USED: The values of pre and postoperative sodium, potassium and calcium serum levels were compared and statistical significance of the difference in values was assessed using Student's paired t test. RESULTS: Statistically significant reduction of serum sodium levels (hyponatremia) and elevation of serum potassium levels (hyperkalemia) were observed post-operatively, which was directly proportional to volume of irrigating fluid used, duration of procedure and volume of prostate gland resected. No significant changes in serum calcium level were observed. CONCLUSIONS: To measure serum electrolytes changes during TURP surgery, it is simple and economical method for indirect assessment of fluid absorption for early identification of TURP syndrome
