ReviewRib fracture fixation: controversies and technical challenges.
Rib fractures are a common injury affecting more than 350,000 people each year in the United States and are associated with respiratory complications, prolonged hospitalization, prolonged pain, long-term disability, and mortality. The social and economic costs that rib fractures contribute to the health care burden of the United States are therefore significant. ⋯ Recently, however, several reports from American centers support an increased application of operative fixation. With this resurgent interest of American surgeons in mind, we review the clinical presentations, potential indications, controversies, and technical challenges unique to rib fracture fixation.

Trauma with resultant hypovolemic shock remains both prevalent and difficult to treat. Standard strategies using volume resuscitation and catecholamine support have historically yielded poor results. Vasopressin has emerged as a possible pharmacologic adjunct, particularly in patients with shock refractory to the administration of fluids and catecholamines. ⋯ It is true that humans show a deficiency in vasopressin minutes after significant hemorrhage that can respond to administration of exogenous vasopressin. When given in physiological dosing regimens, vasopressin appears to be a safe adjunct to other therapy. Definite recommendations regarding indications for use, recommended dose, and long-term outcome in patients with hemorrhagic shock await a much needed prospective, randomized, controlled trial.

ReviewGlucose control and its implications for the general surgeon.
In the face of these conflicting data, how should the practicing surgeon approach the issue of tight glucose control in their critically ill surgical patients? The answer to that question may well change over time as new data emerge. For now, however, it seems reasonable to conclude that tight glucose control to the normal range (80-110 mg/dL) in critically ill general surgery patients (i.e., the Van den Berghe model) is an intriguing but unproven hypothesis that needs to be confirmed by prospective randomized trials in different ICUs and in a relevant patient population. It is quite possible, and probably likely, that levels of hyperglycemia that were previously thought to be inconsequential (180-200 mg/dL) may be harmful when sustained over prolonged periods of time and that better glucose control in the ICU than previously practiced is merited. ⋯ These factors need to be accounted for in daily clinical practice and their roles need to be better understood in future clinical trials. At present, it seems reasonable to attempt to control blood glucose levels in critically ill general surgery patients to moderate levels that avoid deleterious hypoglycemia but have been associated with encouraging clinical results until better data emerge. Until that time, the clinician will need to attempt to balance the potentially detrimental effects of hyperglycemia with the risk of hypoglycemia carefully until future trials involving general surgery patients are completed to clarify this issue.
