Randomized Controlled Trial Multicenter Study Comparative Study
Human polymerized hemoglobin for the treatment of hemorrhagic shock when blood is unavailable: the USA multicenter trial.
Human polymerized hemoglobin (PolyHeme, Northfield Laboratories) is a universally compatible oxygen carrier developed to treat life-threatening anemia. This multicenter phase III trial was the first US study to assess survival of patients resuscitated with a hemoglobin-based oxygen carrier starting at the scene of injury. ⋯ Patients resuscitated with PolyHeme, without stored blood for up to 6 U in 12 hours postinjury, had outcomes comparable with those for the standard of care. Although there were more adverse events in the PolyHeme group, the benefit-to-risk ratio of PolyHeme is favorable when blood is needed but not available.

Anastomotic leak is a dreaded complication of intestinal surgery and has been associated with a high mortality rate. But it is uncertain exactly which patient populations are at risk of death from the leak. We sought to assess the impact of surgeon volume on leak rate and to better understand the relationship of a leak to postoperative mortality. ⋯ The variability in leak rate by surgeons doing similar operations suggests that many leaks may be preventable. But death after a leak is most often a surrogate for a critically ill patient and was infrequently the actual cause of death.

Proficiency in placing infraclavicular subclavian venous catheters can be achieved through practice and repetition. But few data specifically document insertion technical errors, which mentors could teach novice operators to avoid. ⋯ In subclavian central venous access attempts, there are six common technical errors. Mentors can improve novice operators' proficiency by teaching them to avoid these errors.

Obesity is associated with an increased risk of postoperative complications after colectomy for cancer, but it is unclear which specific complications occur more frequently in obese patients. Our objective was to assess the association of body mass index (BMI) on short-term outcomes after colectomy for cancer. ⋯ Compared with normal weight patients, morbidly obese patients had a higher risk of surgical site infection, dehiscence, pulmonary embolism, and renal failure, but not other complications or mortality. Quality initiatives should include these specific complications.

Recent studies suggest that preoperative cardiac stress testing is unnecessary in low to intermediate cardiac risk patients undergoing operations, and that targeted beta blockade is cardiac protective. ⋯ In patients undergoing vascular surgery or major amputation, with low to intermediate cardiac risk, preoperative targeted beta blockade alone is more effective than selective cardiac stress testing and nontargeted beta blockade in preventing cardiac morbidity.
