Comparative Study
Analysis of the effect of conversion from open to closed surgical intensive care unit.
To compare the effect on clinical outcome of changing a surgical intensive care unit from an open to a closed unit. ⋯ Conversion of a tertiary care surgical intensive care unit from an open to closed environment reduced dopamine usage and overall complication and mortality rates. These results support the concept that, when possible, patients in surgical intensive care units should be managed by board-certified intensivists in a closed environment.

John Collins Warren and his act of conscience: a brief narrative of the trial and triumph of a great surgeon.
On examination of the correspondence among the principals involved, as well as the original patent application being prepared by Morton, it has become possible to reconstruct some of the remarkable details attending the first use of ether anesthesia at the Massachusetts General Hos pital in the autumn of 1846. At the time that Warren invited Morton to demonstrate the use of his "ethereal vapor" for anesthesia in a minor operation on Oct. 16, 1846, the exact chemical composition of the agent used was being held secret by Morton; Warren was clearly disturbed by this unethical use of a secret "nostrum." When the time arrived 3 weeks later for its possible use for a serious "capital" operation, Warren employed a simple stratagem of public confrontation to discover from Morton the true nature of the substance to be used. ⋯ Despite this revelation to the immediate participants, a veil of secrecy continued to surround the substance for many months, an anomalous situation evidently traceable to Morton's desire for personal reward from the discovery. It was this matter of secrecy, rather than priority for its discovery, that surrounded the early use of ether anesthesia with controversy and recrimination both in this country and abroad.

To determine if cellular and soluble HLA-DR molecules may be relevant in severely injured patients for the development of gram-positive or gram-negative sepsis. ⋯ In severely injured patients, decreased levels of cellular and soluble HLA-DR appear as early indicators of an immune deviation associated with the development of severe sepsis. Moreover, immune alterations of different cell types may promote distinct kinds of septicemia.

To test the authors' hypothesis of the causal mechanism(s) of postoperative tetany in patients with Graves disease. ⋯ Postoperative tetany occurs in patients with secondary hyperparathyroidism caused by a relative deficiency in calcium and vitamin D because of their increased demand for bone restoration after preoperative medical therapy concomitant with transient hypoparathyroidism after surgery. Calcium and vitamin D supplements may be recommended before and/or after surgery for patients in whom postoperative tetany is expected to develop.
