We hypothesized that the relationship among beta-blocker use, heart rate control, and perioperative cardiovascular outcome would be similar in patients at all levels of cardiac risk. ⋯ Among patients at all levels of cardiac risk undergoing noncardiac surgery, administration of beta-blockers should achieve adequate heart rate control and should be carefully monitored in patients who are not at high cardiac risk.

Many surgeons believe that early mobilization of patients with blunt solid organ injuries increases the risk of delayed hemorrhage. ⋯ The timing of mobilization of patients with blunt solid organ injuries does not seem to contribute to delayed hemorrhage requiring laparotomy. Protocols incorporating periods of strict bed rest are unnecessary.

Comparative Study
Portal vein ligation as an efficient method of increasing the future liver remnant volume in the surgical treatment of colorectal metastases.
To compare the volumetric increase of segments 2 and 3, segment 4, and the caudate lobe after portal vein ligation (PVL) and portal vein embolization (PVE). The small size of the remnant liver and chemotherapy-induced liver injury increase the risk of postoperative hepatic insufficiency after major hepatic resection for colorectal liver metastases. Portal vein ligation has been suggested to be less effective than embolization in inducing hypertrophy of the remnant liver. ⋯ Portal vein ligation is as effective as PVE in inducing hypertrophy of the remnant liver volume.

To critically analyze a large single-institution experience with distal pancreatectomy (DP), with particular attention to the risk factors, outcome, and management of the postoperative pancreatic fistula (PF). ⋯ Pancreatic fistula is the most common complication after DP and its incidence varies depending on the definition applied. Several risk factors for developing a PF were identified. Splenic preservation after DP is safe. The grade of a PF correlates well with clinical outcomes, and most PFs may be managed nonoperatively.

To predict how much blood will be needed based on the number of injured patients arriving after a multiple-casualty incident. ⋯ One unit of blood per evacuated victim is sufficient in a small multiple-casualty incident and 2 U is sufficient in a large multiple-casualty incident. Half of the PRBC units should be blood group O.
