Analysis and modeling of data monitoring vital signs and waveforms in patients in a surgical/trauma intensive care unit (STICU) may allow for early identification and treatment of patients with evolving respiratory failure. ⋯ Among STICU patients, a multivariate model predicted increases in risk of intubation in the following 24 hours based on vital sign data available currently on bedside monitors. Further refinement could allow for earlier detection of respiratory decompensation and intervention to decrease preventable morbidity and mortality in surgical/trauma patients.

Controversy persists as to whether positive operative margins are an independent prognostic factor for resected pancreatic cancer. This study evaluated the impact of the resection margin status on the patterns of recurrence and prognosis after resection for pancreatic cancer. ⋯ In the setting of pancreatectomy, when we evaluated the definitions of R0 resection, the margin status influenced the local recurrence rate but had no impact on the patients' survival.

Despite reports of randomized, control trials and cohort studies that do not support the use of drains, most surgeons routinely place prophylactic, intraperitoneal drains at the time of pancreatic resections. We sought to evaluate the outcome of elective pancreatic resection with or without prophylactic peripancreatic drainage. The primary outcome was the rate of postoperative complications. Total pancreatectomy and pancreatectomy for chronic pancreatitis were excluded. ⋯ In a tertiary, high-volume, Hepatobiliary and pancreatic (HBP) surgery center, the routine prophylactic draining of the abdominal cavity after pancreatic resection did not decrease the frequency or severity of postoperative complications. Prophylactic peripancreatic drainage also did not decrease the requirement for interventional procedures. Interventional radiology and transgastric endoscopic drainage of the post-pancreatectomy collection are feasible and improve patients' outcomes. Malnutrition and the type of operation were independent factors for postoperative complications.

Lung contusion (LC) is a unique direct and focal insult that is considered a major risk factor for the initiation of acute lung injury and acute respiratory distress syndrome. We have shown recently that consumption of nitric oxide (due to excess superoxide) resulting in peroxynitrite formation leads to decreased vascular reactivity after LC. In this study, we set out to determine whether the superoxide scavenger Mn (III) tetrakis (4-benzoic acid) porphyrin chloride (MnTBAP) plays a protective role in alleviating acute inflammatory response and injury in LC. ⋯ Superoxide dismutase mimetic-MnTBAP reduced permeability and oxidative injury in LC and may have a therapeutic role in diminishing inflammation in LC.

The benefit of somatostatin for the prevention of pancreatic fistula has been debated widely in the literature. The aim of this study was to evaluate the efficacy of somatostatin in preventing pancreatic fistulas and improving postoperative outcomes after pancreatic resection. ⋯ Somatostatin use was associated with a significant decrease in both the rate of fistula formation and the number of clinically important fistulas in our pancreatectomy patients. Continued evaluation of somatostatin use in relation to both intraoperative predictors and costa are needed to better define the population that will gain clinical benefit and cost savings.
