Increased awareness of the spleen's immunologic function and the risk of overwhelming post-splenectomy sepsis has aroused interest in methods of splenic preservation in patients with abdominal trauma. During an 8-year period, 164 patients with documented blunt splenic injuries were treated in accordance with an evolving therapeutic program. Definitive treatment included nonoperative management in 19 patients (group I, 11.6%), repair in 50 (group II, 30.5%) and splenectomy in 95 (group III, 57.9%). Mortality and morbidity were higher in group III (6.3% and 34.3% respectively) according to the Injury Severity Score (ISS 33.3 +/- 13). In group II one patient died from severe head injuries. Only one patient failed nonoperative management and required laparotomy with resultant splenectomy on hospital day 10. Observation without surgery has proved to be safe and effective in children (failure incidence less than 10%); success rates in adults would not parallel the experience reported in children because of differences in anatomy and mechanism of injury. Selective criteria, including hemodynamic stability after initial fluid challenge, normal level of consciousness, lack of peritoneal signs, transfusion requirements of less than 4 units of blood, CT demonstration of minor splenic lesion and exclusion of associated abdominal injuries requiring surgery, make eligible for nonoperative management 12 to 18% of adults with anticipated success in over 75%. Operative repair or partial splenectomy can be employed in many patients, both adults and children, with a 1% incidence of rebleeding necessitating reoperation.

Although clinical studies suggest enteral, as opposed to parenteral, feeding lowers morbidity and mortality rates following severe trauma and after sepsis, it is unknown whether gut absorptive capacity (GAC) is indeed maintained under such conditions. To study this, GAC was determined in patients with blunt trauma (n = 8) and with sepsis (n = 11) by the 1-hour D-xylose absorption test. Excluded were patients with ileus, nasogastric output of more than 600 mL/24 hours, or residual gastric content of more than 25 mL after the D-xylose test. Trauma patients (ISS 8-14) and patients with intra-abdominal sepsis had an initial D-xylose test within 24 to 48 hours of admission, at 72 to 96 hours, and then weekly until D-xylose absorption had returned to normal. D-xylose (25 g in 200 mL water) was given via nasogastric tube to patients and orally to healthy volunteers (controls: n = 8). Results show that GAC was depressed at 24 to 96 hours in both groups but returned to normal by 1 to 3 weeks after trauma or resolution of sepsis. Thus (1) gut absorptive capacity was severely depressed early after trauma and after the onset of sepsis; and (2) the 1-hour D-xylose absorption test provided a simple, quantitative assessment of GAC in critically ill patients. Hence, therapeutic agents that restore gut absorptive capacity may be useful for further reducing morbidity and mortality rates following trauma or the onset of sepsis.

Injury has been hypothesized to cause inflammation through systemic release of lipopolysaccharide and pro-inflammatory cytokines, but this has proved difficult to demonstrate in humans. We looked for evidence of an inflammatory pattern of cytokine gene expression by peripheral blood mononuclear cells (PBM) in six polytraumatized patients (ISS = 25 +/- 8) upon ER admission, and in six matched healthy controls. PBM tumor necrosis factor (TNF)-alpha, interleukin (IL)-1 beta, IL-4, IL-6, IL-10, and interferon (IFN)-gamma message was assessed by semi-quantitative reverse-transcription polymerase chain reaction. No increase in expression of any of the pro-inflammatory cytokines (tumor necrosis factor-alpha, IL-1 beta, or IL-6) was found after trauma, and IFN-gamma tended to decrease. Of the immunosuppressive cytokines, IL-10 expression increased 5-fold (p < .05) but no change in IL-4 was discerned. This pattern is fundamentally different from the cytokine expression patterns expected with sepsis or exposure to lipopolysaccharide. These findings are inconsistent with the occurrence of systemic endotoxemia and subsequent global immunocyte activation early after trauma.

From August 91 to December 94, 20 external fixators were used for severely injured patients (avg. ISS 25.2). The fractures were essentially open book with or without lateral compression and vertical lesions. The indication for fixation was treatment of shock and stabilization in 8 cases, stabilization alone in 9 cases, and in 3 cases as complementary fixation after internal fixation of posterior lesions. The fixation of the pelvis was effective on the amount of blood loss. One acetabulum fracture required surgery, two patients had internal fixation for loss of reduction and two others for late pubic and posterior pain. The clinical results are good; they are more related to the severity of the initial lesion than to the mode of fixation or the quality of the reduction. No superficial sepsis or osteitis was observed in relation to the pins.

Sufficient intravascular fluid therapy is of major importance in the treatment of the critically ill patient. The present study assessed whether the cardiorespiratory response of long-term volume replacement with low-molecular weight (LMW) hydroxyethyl starch solution (HES) differs from that of human albumin (HA). According to a randomized sequence, 30 trauma patients (injury severity score [ISS] between 15 and 30) and 30 sepsis patients (secondary to major general surgery) received either 10% HES (mean molecular weight 200,000 daltons; HES trauma [n = 15], HES sepsis [n = 15]) or human albumin 20% (HA trauma [n = 15], HA sepsis [n = 15]) over 5 days to keep pulmonary capillary wedge pressure (PCWP) between 12 and 18 mm Hg. Cardiorespiratory variables were measured by a pulmonary artery catheter on the day of inclusion into the study and daily during the next 5 days. Gastric intramucosal pH (pHi) was measured by tonometry. Central venous pressure and PCWP were comparable within the subgroups (trauma/sepsis) throughout the entire study period. In the trauma patients, cardiac index (CI), oxygen consumption index (VO2I), and oxygen delivery index (DO2I), significantly increased only in the HES-treated patients. In the sepsis patients, CI, VO2I, and DO2I increased and remained higher than baseline only in the HES group (P < 0.01). Right ventricular ejection fraction (RVEF) was reduced (< 40%) in the HA patients and increased only in the HES patients (from 34% +/- 4% to 42% +/- 3%; P < 0.05). pHi remained normal (> 7.35) in both trauma groups and in the HES-treated sepsis patients. In the HA sepsis group, pH, decreased (> 7.20) within the study period (7.15 +/- 0.12 on Day 4), indicating deteriorated splanchnic perfusion. We conclude that long-term intravascular fluid therapy with HA in traumatized and sepsis patients has no advantages in comparison to LMW-HES. In both groups, volume replacement with HES even resulted in improved systemic hemodynamics. Decrease in pHi in the sepsis patients was blunted by HES infusion indicating improved splanchnic perfusion by this regimen of volume therapy.

The therapeutic concept of limb salvage or immediate amputation is controversial in patients with multiple trauma. Sixty-three multiple trauma patients (injury severity score ISS > 18 patients) with blunt arterial injuries were investigated. Twenty-seven had injuries of the upper limb and 36 patients of the lower limb. In 33 cases a limb salvage procedure was performed (group I), while in 30 cases the limb was amputated (group II). Neither group showed a significant difference in age (I: 33 +/- 3, II: 30 +/- 3 years), ISS (I: 30 +/- 2, II: 29 +/- 2 patients), time of ischemia (I: 238 +/- 30, II: 203 +/- 20 min) ICU stay (I: 18 +/- 4, II: 19 +/- 4 days). Lethality and morbidity were slightly increased in group I (death: I: n = 8; II: n = 4; MOF: I: n = 5; II: n = 3; Sepsis: I: n = 11, II: n = 4). No differences were found in the incidence of local infections (I: n = 12, II: n = 10). Secondary amputations were performed in 7 patients after 12 +/- 2 days (range 3-40; median: 5 days). We conclude that limb salvage did not increase the risk for severe complications. Lethality and morbidity were related to the severity of the injury. To prevent complications, secondary amputations had to be performed early.

In a prospective study (400 patients, intensive care stay > 18 h) the following data were documented daily: Clinical sepsis, a modified sepsis score, Apache II-score, number of organ failure, Elastase-concentrations and injury severity score (ISS > or = 20 = polytrauma). On admission day a prognostic assessment for early diagnosis of septic complications during intensive care could be demonstrated by a combination of the modified sepsis score and the number of organ failures and the presence of polytrauma. All other parameters did not have any predictive value.

To evaluate the nutritional, metabolic and immune effects of dietary arginine, glutamine and omega-3 fatty acids (fish oil) supplementation in immunocompromised patients, we performed a prospective study on the effect of immune formula administered to 11 severe trauma patients (average ISS = 24), 10 burn patients (average % TBSA = 48) and 5 cancer patients. Daily calorie and protein administration were based on the patient's severity (Stress factor with the range of 35-50 kcal/kg/day and 1.5-2.5 g/kg/day, respectively) Starting with half concentration liquid immune formula through nasogastric tube by continuous drip at 30 ml/h and increasing to maximum level within 4 days. The additional energy and protein requirement will be given either by parenteral or oral nutritional support. Various nutritional, metabolic, immunologic and clinical parameters were observed on day 0 (baseline), day 3, 7, and 14. Analysis was performed by paired student-t test. Initial mean serum albumin and transferrin showed mild (trauma) to moderate (burn and cancer) degree of malnutrition. Significant improvement of nutritional parameters was seen at day 7 and 14 in trauma and burn patients. Significant increase of total lymphocyte count (day 7, P < 0.01), CD4 + count (day 7, p < 0.01), CD8 + count (day 7, p < 0.0005 & day 14, p < 0.05), complement C3 (day 7, p < 0.005 day 14, p < 0.01), IgG (day 7, and 14, p < 0.0005), IgA (day 7, p < 0.0005 & day 14, p < 0.05), in all patients. C-reactive protein decreased significantly on day 7 (p < 0.0005) and day 14 (p < 0.005). 3 cases of burn wound infection, one case of UTI and one case of sepsis were observed. Two cases of hyperglycemia in burn, 3 cases of hyperbilirubinemia in trauma, 10 cases of elevated LFT (5 trauma/5 burn), and one case of hyponatremia in cancer patients were observed. Two cases of nausea, 4 cases of vomiting, 5 cases of diarrhea (< 3 times/day), 2 cases of abdominal cramp, 1 case of distension were observed. The feeding of IMMUNE FORMULA was well tolerated and significant improvement was observed in nutritional and immunologic parameters as in other immunoenhancing diets. Further clinical trials of prospective double-blind randomized design are necessary to address the so that the necessity of using immunonutrition in critically ill patients will be clarified.

The effects of kinetic therapy on the oxygenation in the injured lung of 111 polytrauma patients were analysed in an open prospective study. The patient collective comprised 82 men and 29 women. For the total group, the average age was 38.3 years (+/- 16.1). The initial ISS was 39.3 points (+/- 18.9), and the APACHE II evaluated 24 h after including the patient into the study was 13.1 (+/- 5.2). The data of 3 treatment groups were evaluated: 1, acute respiratory disease (ARDS, n = 42); 2, acute lung injury (ALI, n = 36); and 3, prophylaxis (n = 33, a group of prophylactically treated patients with a PaO2/FiO2 ratio > or = 300 and an ISS > or = 15). Positioning therapy was administered in group 3 in order to prevent atelectases, and respirator-induced lung injuries during a foreseeable, relatively long period in the intensive care unit in view of the severity of the trauma. The mean treatment time in the kinetic bed was 6.3 days (+/- 3.9), the time on respirator 18.5 days (+/- 15.4). The patients stayed in the ICU 22.4 days (+/- 15.4) and left the hospital after 35.1 days (+/- 27.7). For scoring the severity of respiratory failure, the lung injury score (LIS) according to Murray and the SOFA score lung (sepsis-related organ failure assessment) according to Vincent were evaluated. The LIS at time of recruitment into the study was 2.2 (+/- 1.0), the SOFA score lung 3.0 (+/- 0.9). In the ALI and ARDS groups a significant improvement in oxygenation was observed (p < 0.0001). No patient of the prophylaxis group developed an ALI or ARDS. The mortality rate in the total group of 10.8% was relatively low in comparison with other published data. Consistent kinetic therapy integrated in a standardised treatment regimen contributes towards improving the negative outcome to date of patients with severe respiratory failure after major trauma.

We determined concentrations of IL-12 (p70), IL-12 (p40) and concomitantly of IL-10 in plasma and partly in culture supernatants stimulated peripheral blood mononuclear cells (PBMC) of 30 traumatized patients (ISS: 17-57; APACHE II: 7-45; during their course on the intensive care unit. Our results showed that individually systemic IL-12 could be extremely increased post trauma (p70 > 1000 pg/ml and p40 > 2500 pg/ml). Patients who succumbed to sepsis/multi organ failure, partly exhibited subnormal systemic IL-12-values. The capacity to synthesize IL-12-p40 from SAC-stimulated PBMC in vitro was individually increased in non-septic patients and correlated to respective plasma values.
