Dynamic changes in respiratory frequency/tidal volume may predict failures of ventilatory liberation in patients on prolonged mechanical ventilation and normal preliberation respiratory frequency/tidal volume values.
Rapid shallow breathing index (RSBI, respiratory frequency [f] divided by tidal volume [Vt]) has been used to prognosticate liberation from mechanical ventilation (LMV). We hypothesize that dynamic changes in RSBI predict failed LMV better than isolated RSBI measurements. We conducted a retrospective study of patients who were mechanically ventilated (MV) for longer than 72 hours. ⋯ The RSB-P was higher for failed LMVs (118) than for successful LMVs (48.8, P < 0.01) with failures having larger proportion of pre-LMV d-RSBI values greater than 1.5 (39.0 vs 10.7%, P < 0.03). Pre-LMV RSB-P may offer early prediction of failed LMV in patients on MV for longer than 72 hours despite normal pre-LMV i-RSBI. Divergence between RSB-P for successful and failed LMVs occurred earlier than i-RSBI divergence with a greater proportion of pre-LMV d-RSBI greater than 1.5 among failures.

Recombinant factor VIIa to correct coagulopathy in patients with traumatic brain injury presenting to outlying facilities before transfer to the regional trauma center.
Timely correction of coagulopathy in patients with traumatic brain injury (TBI) improves mortality. Recombinant, activated factor VII (VIIa) has been identified as an effective method to correct coagulopathy in patients with TBI. We performed a retrospective study (January 1, 2008-December 31, 2009) of all patients with TBI and coagulopathy (international normalized ratio (INR) > 1.5) transferred to our Level I trauma center. ⋯ Upon arrival to our trauma center the VIIa group had a lower INR (1.0 vs 3.0, P = 0.02) and lower mortality (0% vs 39%, P = 0.03). In coagulopathic patients with TBI presenting to outlying institutions with limited resources to quickly provide plasma, VIIa efficiently corrects coagulopathy before transfer to definitive care at the regional trauma center. More rapid correction of coagulopathy with VIIa in this patient population may improve mortality.

Quality of life after laparoscopic cholecystectomy for biliary dyskinesia in the pediatric population: a pilot study.
This pilot study examined symptom relief and quality of life in pediatric patients who received laparoscopic cholecystectomy surgery at our institution for biliary dyskinesia. We used two validated questionnaires: the Child Health Questionnaire (CHQ-PF28), to assess general well-being, and the Gastrointestinal Quality of Life Index (GIQLI), to measure gastrointestinal-related health. After Institutional Review Board approval, all patients under the age of 18 years who underwent laparoscopic cholecystectomy for biliary dyskinesia between November 2006 and May 2010 received mailed questionnaires. ⋯ Children experiencing long-term symptom cessation after laparoscopic cholecystectomy reported higher quality of life than those who had incomplete or only short-term relief. However, regardless of the degree of symptom relief, the degree of quality of life experienced by our study sample of patients with biliary dyskinesia is lower than that of a comparable U. S. pediatric sample.

The impact of American College of Surgeons trauma center designation and outcomes after early thoracotomy: a National Trauma Databank analysis.
Trauma centers are designated by the American College of Surgeons (ACS) into four different levels based on resources, volume, and scientific and educational commitment. The purpose of this study was to evaluate the relationship between ACS center designation and outcomes after early thoracotomy for trauma. The National Trauma Databank (v. 7.0) was used to identify all patients who required early thoracotomy. ⋯ Nonteaching institutions however, were independently associated with poorer outcomes after early thoracotomy. These findings may have important implications in educational commitment of institutions. Further prospective evaluation of these findings is warranted.
