Intra-abdominal compartment syndrome (ACS) is a devastating complication in burn patients with a high mortality. Apart from high-volume resuscitation as known risk factor, also mechanical ventilation seems to influence the development of ACS. The TIRIFIC trial is a retrospective, matched-pair analysis. Thirty-eight burn patients with ACS were matched for burned total body surface area (TBSA), age and mechanical ventilation (MV). In contrast to the already published part I addressing fluid resuscitation as a risk factor, the parameters analyzed in part II were maximum and average PEEP and peak pressure levels as well as serum lactate levels and prokinetic therapy. For subgroup-analysis the ACS-group was split up into an early-onset and late-onset ACS-group according to the median time between burn trauma and ACS. The groups were analyzed with a two-sided Mann-Whitney-U-test with significance set at p less then 0.05. In the ACS-group all ventilation pressures (maximum and average PEEP and peak pressure levels) were significantly increased compared to control. The subgroup-analysis showed significantly increased maximum PEEP and peak pressure levels in early- and late-onset ACS-groups versus control. learn more However, the average ventilation pressure levels were only increased in the early-onset ACS-group (average PEEP p = 0.0069; average peak pressure p = 0.05). The TIRIFIC trial showed significantly increased ventilation pressures in the ACS group in general as a surrogate parameter to support early diagnostics. Especially, maximum PEEP levels and peak pressures are significantly increased in both, early- and late-onset ACS. As an addition to the actual WSACS guidelines we suggest IAP measurement in mechanically ventilated burn patients if ventilating pressures are rising continuously without a clear pulmonary or otherwise identifiable reason. INTRODUCTION Aggressive fluid resuscitation has been extensively discussed after the establishment of fluid creep phenomenon as a morbidity and mortality factor in burn children. Sepsis is currently the leading cause of death in survivors of burn shock. OBJECTIVES To evaluate the association between fluid creep and infection in burn children exposed to two different fluid resuscitation strategies with the use of albumin. METHODS A cohort of 46 burn children with 15-45% of body surface area (BSA) admitted up to 12 h after the incident were evaluated. Patients from early albumin group (n = 23) received 5% albumin between 8 and 12 h from injury and patients from delayed albumin group (n = 23) received 5% albumin after 24 h. Outcomes analysed were development of fluid creep, length of stay in the hospital, number of surgery procedures and infection until hospital discharge. RESULTS Compared to the delayed group, patients that received early albumin had a shorter length of stay in the hospital (p = 0.007), less fluid creep (4.3% × 56.5%) (p less then 0.001), less skin graft procedure (47.8% × 78.3%) (p = 0.032) and less debridement (73.9% × 100%) (p = 0.022). Both length of stay in the hospital and fluid creep arising were associated with infection (p less then 0.05). CONCLUSION Fluid creep, surgery procedures and length of stay in hospital parameters showed better results in burn children treated with early albumin. Fluid creep and length of stay in the hospital were associated with infection, providing a negative prognosis. Our aim was to investigate the bone thickness at the site of titanium miniplates inserted to retain nasal prostheses. We studied 13 patients who had had titanium miniplates inserted for retention of nasal prostheses with a total of 60 titanium bone screws. A trajectory along each bone screw was segmented in fused computed tomographic (CT) data. Bone thickness was measured along this trajectory on the preoperative CT. The median bone thickness at the positions of the screws implanted on the frontal process of the maxillary bone was 1.4 (range 0.2-6.9) mm (mean 1.8).
