RESUMO
OBJECTIVE: To investigate the risk of postoperative surgical site infections after plate fixation of the anterior pelvic ring subsequent to preperitoneal pelvic packing (PPP). DESIGN: Retrospective observational cohort study. SETTING: Level I academic trauma center. PATIENTS: Adult trauma patients with unstable pelvic ring injuries requiring surgical fixation of the anterior pelvic ring. INTERVENTION: Pelvic plate fixation was performed as a staged procedure after external fixation and PPP/depacking (PPP group; n = 25) or as a single-stage primary internal fixation (control group; n = 87). MAIN OUTCOME MEASURE: Incidence of postoperative surgical site infections of the pelvic space. RESULTS: Anterior pelvic plate fixation was performed in 112 patients during a 5-year study period. The PPP group had higher injury severity scores and transfused packed red blood cells than the control group (injury severity score: 46 ± 12.2 vs. 29 ± 1.5; packed red blood cells: 13 ± 10 vs. 5 ± 2; P < 0.05). The mean time until pelvic depacking was 1.7 ± 0.6 days (range: 1-3 days) and 3.4 ± 3.7 days (range: 0-15 days) from depacking until pelvic fracture fixation. Two patients in the PPP group and 8 patients in the control group developed a postoperative infection requiring a surgical revision (8.0% vs. 9.2%; n.s.). Both PPP patients with a pelvic space infection had undergone anterior plate fixation for associated acetabular fractures. CONCLUSIONS: These data support the safety of the PPP protocol for bleeding pelvic ring injuries due to the lack of increased infection rates after fracture fixation. Caution should be applied when considering PPP in patients with associated acetabular fractures. LEVEL OF EVIDENCE: Therapeutic Level III.

OBJECTIVE: To investigate the safety and feasibility of performing definitive fracture fixation in multiply injured patients in the presence of an open abdomen after laparotomy. DESIGN: Retrospective observational cohort study. SETTING: Level-I academic trauma center. PATIENTS: Adult polytrauma patients with the presence of an open abdomen after "damage control" laparotomy and associated major fractures of long bones, acetabulum, pelvis, or spine, requiring surgical repair (n = 81). INTERVENTION: Timing of definitive fracture fixation in relation to the timing of abdominal wall closure. MAIN OUTCOME MEASURE: Incidence of orthopedic surgical site infections. RESULTS: During a 15-year time window from January 1, 2000 until December 31, 2014, we identified a cohort of 294 consecutive polytrauma patients with an open abdomen after laparotomy. Surgical fixation of associated fractures was performed after the index laparotomy in 81 patients. In group 1 (n = 32), fracture fixation occurred significantly sooner despite a concurrent open abdomen, compared with group 2 (n = 49) with abdominal wall closure before fixation (mean 4.4 vs. 11.8 days; P = 0.01). The incidence of orthopaedic surgical site infections requiring a surgical revision was significantly lower in group 1 (3.1%) compared to group 2 (30.6%; P = 0.002). CONCLUSIONS: Definitive fracture fixation in the presence of an open abdomen is performed safely and associated with a significant decrease in clinically relevant surgical site infections, compared with delaying fracture fixation until abdominal wall closure. These data suggest that the strategy of imposing a time delay in orthopaedic procedures while awaiting abdominal wall closure is unjustified. LEVEL OF EVIDENCE: Therapeutic Level III.

BACKGROUND: A 2015 American Association for the Surgery of Trauma trial reported a 32% mortality for pelvic fracture patients in shock. Angioembolization (AE) is the most common intervention; the Maryland group revealed time to AE averaged 5 hours. The goal of this study was to evaluate the time to intervention and outcomes of an alternative approach for pelvic hemorrhage. We hypothesized that preperitoneal pelvic packing (PPP) results in a shorter time to intervention and lower mortality. METHODS: In 2004, we initiated a PPP protocol for pelvic fracture hemorrhage. RESULTS: During the 11-year study, 2,293 patients were admitted with pelvic fractures; 128 (6%) patients underwent PPP (mean age, 44 ± 2 years; Injury Severity Score (ISS), 48 ± 1.2). The lowest emergency department systolic blood pressure was 74 mm Hg and highest heart rate was 120. Median time to operation was 44 minutes and 3 additional operations were performed in 109 (85%) patients. Median RBC transfusions before SICU admission compared with the 24 postoperative hours were 8 versus 3 units (p < 0.05). After PPP, 16 (13%) patients underwent AE with a documented arterial blush.Mortality in this high-risk group was 21%. Death was due to brain injury (9), multiple organ failure (4), pulmonary or cardiac failure (6), withdrawal of support (4), adverse physiology (3), and Mucor infection (1). Of those patients with physiologic exhaustion, 2 died in the operating room at 89 and 100 minutes after arrival, whereas 1 died 9 hours after arrival. CONCLUSIONS: PPP results in a shorter time to intervention and lower mortality compared with modern series using AE. Examining mortality, only 3 (2%) deaths were attributed to the immediate sequelae of bleeding with physiologic failure. With time to death under 100 minutes in 2 patients, AE is unlikely to have been feasible. PPP should be used for pelvic fracture-related bleeding in the patient who remains unstable despite initial transfusion. LEVEL OF EVIDENCE: Therapeutic study, level IV.

BACKGROUND: Massive transfusion protocols (MTPs) have become standard of care in the management of bleeding injured patients, yet strategies to guide them vary widely. We conducted a pragmatic, randomized clinical trial (RCT) to test the hypothesis that an MTP goal directed by the viscoelastic assay thrombelastography (TEG) improves survival compared with an MTP guided by conventional coagulation assays (CCA). METHODS: This RCT enrolled injured patients from an academic level-1 trauma center meeting criteria for MTP activation. Upon MTP activation, patients were randomized to be managed either by an MTP goal directed by TEG or by CCA (ie, international normalized ratio, fibrinogen, platelet count). Primary outcome was 28-day survival. RESULTS: One hundred eleven patients were included in an intent-to-treat analysis (TEG = 56, CCA = 55). Survival in the TEG group was significantly higher than the CCA group (log-rank P = 0.032, Wilcoxon P = 0.027); 20 deaths in the CCA group (36.4%) compared with 11 in the TEG group (19.6%) (P = 0.049). Most deaths occurred within the first 6 hours from arrival (21.8% CCA group vs 7.1% TEG group) (P = 0.032). CCA patients required similar number of red blood cell units as the TEG patients [CCA: 5.0 (2-11), TEG: 4.5 (2-8)] (P = 0.317), but more plasma units [CCA: 2.0 (0-4), TEG: 0.0 (0-3)] (P = 0.022), and more platelets units [CCA: 0.0 (0-1), TEG: 0.0 (0-0)] (P = 0.041) in the first 2 hours of resuscitation. CONCLUSIONS: Utilization of a goal-directed, TEG-guided MTP to resuscitate severely injured patients improves survival compared with an MTP guided by CCA and utilizes less plasma and platelet transfusions during the early phase of resuscitation.
