Impact of Bedside Laparotomy Simulation and Microlearning on Trauma Nurse Role Clarity, Knowledge, and Confidence.

BACKGROUND: The care of patients undergoing low-volume, high-risk emergency procedures such as bedside laparotomy (BSL) remains a challenge for surgical trauma critical care nurses. OBJECTIVES: This study evaluates simulation and microlearning on trauma nurse role ambiguity, knowledge, and confidence in caring for patients during emergency BSL. METHODS: The study is a single-center, prospective pretest-posttest design conducted from September to November 2022 at a Level I trauma center in the Mid-Atlantic United States using simulation and microlearning to evaluate role clarity, knowledge, and confidence among surgical trauma intensive care unit (STICU) nurses. Participants, nurses from a voluntary convenience sample within a STICU, attended a simulation and received three weekly microlearning modules. Instruments measuring role ambiguity, knowledge, and confidence were administered before the simulation, after, and again at 30 days. RESULTS: From the pretest to the initial posttest, the median (interquartile range [IQR]) Role Ambiguity scores increased by 1.0 (1.13) (p < .001), and at the 30-day posttest, improved by 1.33 (1.5) (p < .001). The median (IQR) knowledge scores at initial posttest improved by 4.0 (2.0) (p < .001) and at the 30-day posttest improved by 3.0 (1.75) (p< .001). The median (IQR) confidence scores at initial posttest increased by 0.08 (0.33) (p = .009) and at the 30-day posttest improved by 0.33 (0.54) (p = .01). CONCLUSIONS: We found that simulation and microlearning improved trauma nurse role clarity, knowledge, and confidence in caring for patients undergoing emergency BSL.

Retrospective study of polytrauma patients's medical records that presented abdominal trauma, comperad to abdominal trauma and extra-abdominal injuries

This study sought to retrospectively assess the relationship between intra and extra-abdominal injuries in polytrauma patients undergoing laparotomy at the Regional University Hospital of Maringá between 2017 and 2018.This study was based on 111 electronic medical records from the Brazilian public health system "SUS", admitted to the hospital due to trauma and undergoing laparotomy, comparing two groups: abdominal injury without extra-abdominal injury (WoEI) and abdominal injury with extra-abdominal injury (WiEI).A total of 111 medical records were analyzed, 57 from 2017 and 54 from 2018. Of these 111records, 43 (39%) were trauma victims with only abdominal injuries and 68 (61%) trauma victims with abdominal and extra-abdominalinjuries. Most patients were male (85%), with an average age of 33 years, ranging from 14 to 87 years. In statistical analysis, according to the T-test, there was significance (p > 0.05) between the WoEI and WiEI groups for data collected regarding death rates and hospitalization days. As for the morbidity rate and difference between genders (male and female), there was no statistical significance (p < 0.05).Polytraumapatients are exposed to greater kinetic energy, with more severe conditions and therefore required more in-hospital care.
