Review Comparative StudyPeripherally inserted central venous catheters are not superior to central venous catheters in the acute care of surgical patients on the ward.
Peripherally inserted central venous catheters (PICC) have supplanted central venous catheters (CVC) for the administration of intravenous antibiotics and total parenteral nutrition to patients in our hospital. From the literature, it appears that this change has occurred in a number of other surgical units. Accounting for the change are the expected advantages of low complication rates at insertion, prolonged use without complications and interruption, and cost- and time-savings. ⋯ We believe that there is no clear evidence that PICC is superior to CVC in acute care settings. Each approach offers its own advantages and a different profile of complications. Therefore, the choice of central venous access should be individualized for surgical patients on the ward. More comparative prospective studies are needed to document the advantages of PICC over CVC.

Biography Historical Article"To afford the wounded speedy assistance": Dominique Jean Larrey and Napoleon.
Dominique Jean Larrey (1766-1842) has been described as the father of modern military surgery and is considered even today as the model military surgeon. He developed a plan of rapid evacuation of wounded soldiers from the battlefield during combat, using flexible medical units which he named ambulances volantes ("flying ambulances"). He won the admiration of Napoleon Bonaparte (1769-1821), who was amazed by the results of Larrey's sanitary system. ⋯ The surgeon became a master of wound management and limb amputation. In his vivid battlefield journals, Larrey documented the course of tetanus, the pathophysiology of cold injury, the effective control of hemorrhage, the drainage of empyema and hemothorax, the aspiration of pericardial effusion or hemopericardium, and the packing of sucking chest wounds. Larrey established a categorical rule for the triage of war casualties, treating the wounded according to the observed gravity of their injuries and the urgency for medical care, regardless of their rank or nationality.

Sensitivity and specificity of intraoperative recurrent laryngeal nerve stimulation test for predicting vocal cord palsy after thyroid surgery.
Recurrent laryngeal nerve (RLN) palsy after thyroidectomy, although infrequently encountered, can decrease quality of life. In addition to the hoarseness that occurs with unilateral RLN palsy, bilateral RLN palsy leads to dyspnea and often to life-threatening glottal obstruction. Therefore, intraoperative awareness of the nerve's status is of great importance. This study examined the sensitivity and specificity of a palpation technique to detect contraction of the posterior cricoarytenoid muscle (PCA) through the posterior hypopharyngeal wall while the RLN was being stimulated with a disposable nerve stimulator during thyroid surgery (the laryngeal palpation test) to predict postoperative RLN deficits. ⋯ The laryngeal palpation test is not a particularly useful method for predicting the level of RLN function after thyroidectomy. All patients must be examined postoperatively by direct laryngoscopy or laryngofiberoscopy to check vocal cord mobility. Even if there is no contraction of the PCA and we detect vocal cord palsy immediately after surgery, vocal cord palsy often recovers within 1 year when visual preservation of RLN is successful.

Randomized Controlled Trial Multicenter StudyHemoglobin-based oxygen carriers in trauma care: scientific rationale for the US multicenter prehosptial trial.
The greatest need for blood substitutes worldwide is in patients with unanticipated acute blood loss, and trauma is the most likely scenario. The blood substitutes reaching advanced clinical trials today are red blood cell (RBC) substitutes derived from hemoglobin. The hemoglobin-based oxygen carriers (HBOCs) tested currently in advanced clinical trials are polymerized hemoglobin solutions. ⋯ To date, >500 injured patients have been enrolled in this multicenter trial, and the final interim analyses support the original target of 720.

Randomized Controlled TrialPreoperative enteral immunonutrition improves postoperative outcome in patients with gastrointestinal cancer.
The purpose of this study was to evaluate the effect of preoperative immunonutrition pharmaceutics (IMPACT) diet versus standard enteral nutrition (EN) on the nutritional status and immunity of patients with colorectal or gastrointestinal (GI) cancer and to evaluate whether it influences the incidence of postoperative complication. ⋯ Preoperative enteral IM in patients with GI cancer improves nutritional status and immunity and decreases the incidence of postoperative complications and infections.
