Purpose
Managing patients with hemorrhagic shock is mainly dependent on stopping the bleeding as fast as possible. Emergency Department laparotomy (EDL) is considered one of the approaches to control intra-abdominal bleeding rapidly. This study aims to evaluate the outcomes of EDL in a regional trauma center of Pusan National University Hospital in a 4-year period.
Methods
The medical records and data of patients who underwent EDL from January 2016 to December 2019 were analyzed. Patients who underwent preperitoneal pelvic packing only or did not receive surgery immediately after EDL were excluded.
Results
Twenty-four patients who underwent EDL were included in the study. 18 patients had sustained blunt trauma, and 6 suffered from penetrating injuries. Small bowel mesentery and liver injuries were the most frequent. Increase of median systolic blood pressure (SBP) after EDL was 55.5 mmHg. Four (16.7%) out of the 24 survived; one of the four survivors received cardiopulmonary resuscitation (CPR). In the nonsurvivor group, Injury Severity Score was significantly higher (p = 0.013), initial pH was lower (p = 0.035) and the amount of packed red blood cells transfusion after EDL was significantly higher (p = 0.013) than those in the survivor group.
Conclusion
The mortality rate was very high in trauma patients who were required EDL. Although EDL was not proved to be an effective procedure for resuscitation in trauma patients, it could be considered as one of the treatment options for trauma patients in extremis. Further studies are required to examine the effects of EDL.

Purpose:

To assess the effects of whole-body computed tomography (WBCT) on severely injured trauma patients.

Methods:

After the installation of a WBCT scanner, we compared 48 patients who underwent the WBCT (WBCT cohort) with 40 patients prior to the WBCT (pre-WBCT cohort). We evaluated the number of CT, radiation exposure, time interval to decision and clinical outcomes such as length of intensive care unit stay, ventilation period, and acute kidney injury rates.

Results:

In the WBCT cohort, the number of CT scans was significantly less (3.5 times) than in the pre-WBCT cohort (5.5 times; p<0.001). The radiation exposure was significantly lower in the WBCT cohort (24.5 mSv) than in the pre-WBCT cohort (31.3 mSv; p=0.040). The amount of radio-contrast used differed between the groups, but not significantly. Although there were fewer acute kidney injuries in the WBCT cohort (27.1%) than in pre-WBCT cohort (37.5%; p=0.296), especially severe injuries (stage 3 Acute Kidney Injury [AKI] Network: 17.5% in pre-WBCT vs. 6.3% in WBCT; p=0.059), the difference did not reach statistical significance. The hospital length of stay was significantly shorter in the WBCT cohort (21.42 days) than in the pre-WBCT cohort (32.38 days, p=0.019). However, there were no significant differences in the time interval to decision, intensive care unit stay, ventilation days, and mortality.

ConclusionL

The WBCT decreased the number of CT scans and subsequent less use of radio-contrast amount. It also tended to reduce severe AKI.
