Seprafilm in Open Abdomens: a Study of Wound and Adhesion Characteristics in Trauma Damage Control Patients (OASIT)

• Wound healing characteristics [ Time Frame: Participants will be followed until their open abdomen is closed. Depending on the nature and severity of the wound, this period may last as long as 1 year after the patient has been discharged. ] [ Designated as safety issue: Yes ]
  There will not be a fixed duration of outpatient follow-up (fixed follow-up in trauma patients is not practical due to the unpredictable nature of trauma population), an average (mean) follow-up will be determined for the entire cohort of patients for the purposes of the study, up to a maximum of 1 year (if available) following hospital discharge.
  
  

• Adhesion characteristics [ Time Frame: Up to 1 year ] [ Designated as safety issue: No ]
  Patients undergoing surgery in either arm of the study will be assessed for severity of intra-abdominal adhesions during each return trip to the operating room. Any patients taken back to the operating room for up to 1 year will be assessed for adhesion severity.
  
  

Data to be analyzed includes:

Age, gender, traumatic injuries, trauma alert level, procedure information, length of hospital stay, length of ICU stay, interval between admission and initial operation, interval between operations, whether operation took place during the day or night, duration of operation in minutes, number of surgeons present during the operation, description of the initial operation, justification for using damage control approach, complications noted, injuries missed or delayed in diagnosis, Acute Physiology and Chronic Health Evaluation II (APACHE II) calculations at various time points, Simplified Acute Physiology Score (SAPS II) calculations at various time points, Glasgow Coma Score (GCS) calculations at various time points, changes in GCS at over time, Injury Severity Score (ISS) at various time points, Abbreviated Injury Scale (AIS) at various time points, Penetrating Abdominal Trauma Index score (if applicable) at various time points, complete blood count (CBC) results at various time points, blood chemistry results at various time points, blood gas results at various time points, subject randomization information, number of operations, adhesion scores (Zuhlke and Yaacobi) for each operative procedure, contamination score for each operative procedure, diagnosis and description of sub-procedures for each operative procedure, wound characteristics from the start and end of all operative procedures (e.g. length and width of the fascia and skin), type of abdominal coverage or closure, discharge destination (e.g. home, short term rehabilitation facility, etc.), Functional Outcome Measure score, Glasgow Outcome Score (GOS) at various time points, number and interval of post discharge follow-up visits, wound characteristics since discharge at several time points and complications/complaints noted since discharge at several time points.
