Background: Whole blood is a product that contains all three blood components (plasma, red blood cells, and platelets). This systemic review and meta-analysis was conducted to identify barriers and obstacles to establishing whole blood transfusion protocols in civilian hospitals. Methods: The study was conducted using PRISMA guidelines with PROSPERO registration No. CRD42024519898. Traumatic patients who needed or received whole blood transfusion were included. A systematic literature review employed a comprehensive search strategy through the PubMed, Google Scholar, Web of Science, ScienceDirect, and ProQuest databases. Meta-analysis was utilized to analyze the outcomes. The risk of bias was assessed using the Newcastle–Ottawa Scale. Results: In total, 310 studies were identified, and 11 studies met the inclusion criteria. The following intervals were used to assess the prevalence of mortality: 6 h 12.15% (0.081, 95% CI [0.023, 0.139]), 24 h 14.08% (0.141, 95% CI [0.111, 0.171]), delayed mortality (28–30 days) 22.89% (0.284, 95% CI [0.207, 0.360]), and in-hospital 18.72%, with relative risk (0.176, 95% CI [0.114,0.238]). Conclusions: Traumatic patients can be effectively resuscitated and stabilized with whole blood transfusion (WBT), but it is essential to provide ongoing critical care, address logistical challenges, and prevent blood product wastage. We recommend utilizing WBT in the early stages of resuscitation for adult civilian trauma patients.

Biliary pancreatitis is a common complication of gallstones. Although most patients experience mild disease, around 20% may develop severe pancreatitis with an increased risk of serious complications during recurrent attacks. The objective of our study is to compare the surgical outcomes and length of stay for early versus delayed cholecystectomy, performed within the same admission, for mild pancreatitis in a Saudi tertiary center with an established Acute Care Surgey Unit. This retrospective cohort study included all patients who underwent cholecystectomy during the index admission for biliary pancreatitis between January 2017 and January 2020. Surgical outcomes and hospital length of stay were collected and analyzed to assess overall outcomes for early and delayed cholecystectomy groups. The early group was defined as surgery performed within 72 hours of presentation. Eighty-six patients were included and allocated to the early and delayed cholecystectomy groups. The median length of hospital stay was significantly shorter in the early cholecystectomy group (4 days, IQR 3–5) compared to the delayed group (7 days, IQR 6–9) (P < .001). There was no significant difference in operative time and postoperative complications. Early cholecystectomy for mild biliary pancreatitis appears safe and feasible and may result in a shorter hospital stay.

Bowel perforation is an emergency condition that requires critical thinking and readily intervention; nevertheless, on occasions, its presentation can be challenging to diagnose. Several etiologies could cause bowel perforation, including obstruction, mass, inflammation, ischemia, etc. On rare occasions, a foreign body could be the cause of perforation, which mandates a detailed history and focused review of the images when the patient’s condition allows. We report a case of ileal perforation caused by an ingested wooden toothpick that was suspected on the CT images, which the patient has no memory of ingesting.

Traumatic liver injury remains a significant contributor to trauma-related morbidity and mortality worldwide. In Saudi Arabia, motor vehicle accidents (MVAs) are the predominant mechanism of injury, particularly among young adults. This study aimed to evaluate the clinical characteristics, management strategies, and outcomes of patients with liver trauma over a ten-year period at a tertiary academic level-one trauma center. A retrospective cohort study was conducted from January 2015 to December 2024. All adult patients (aged 18–65 years) who sustained blunt or penetrating liver injuries and underwent a pan-CT trauma survey were included. Demographic data, Injury Severity Scores (ISSs), imaging timelines, management approach, and clinical outcomes were analyzed. Statistical analysis was performed using JASP software with a significance threshold set at p < 0.05. A total of 111 patients were included, with a mean age of 33 ± 12.4 years; 78.1% were male. MVAs were the leading cause of injury (75.7%). Most patients (80.2%) had low-grade liver injuries and received non-operative management (NOM), with a high NOM success rate of 94.5%. The median time to CT was 55 ± 64 min, and the mean time to operative or IR intervention was 159.9 ± 78.8 min. Complications occurred in 32.4% of patients, with ventilator-associated pneumonia (19.8%) being most common. The overall mortality was 6.3%. Multivariate analysis revealed that shorter time to CT significantly reduced mortality risk (OR = 0.5, p < 0.05), while a positive e-FAST result was strongly associated with increased mortality (OR = 3.3, p < 0.05). Higher ISSs correlated with longer monitored unit stays (ρ = 0.3, p = 0.0014). Traumatic liver injuries in this cohort were predominantly low-grade and effectively managed conservatively, with favorable outcomes. However, delays in imaging and operative intervention were observed, underscoring the requirement for streamlined trauma workflows. These findings highlight the requirement for continuous trauma system improvement, including protocol optimization and timely access to imaging and surgical intervention.

Traumatic Brain Injuries (TBIs) pose a significant global health burden, with high mortality and long-term disability rates. This retrospective cohort study investigates the implementation and impact of the Brain Trauma Foundation (BTF) guidelines on TBI management in a Saudi Arabian tertiary care center. Data from the pre-implementation (2012) and post-implementation (2022) of BTF guidelines periods were compared. The patient demographics, injury severity, guideline adherence, and outcomes were analyzed. The results revealed a 33% increase in severe TBI cases from 2012 to 2022, possibly due to the development of a well-established trauma system designed to manage such cases. More importantly, implementing the BTF guidelines led to a marked improvement in patient outcomes. Compliance with guidelines, including the avoidance of hypoxia and hypotension, hyperosmolar therapy, and DVT prophylaxis significantly increased post-implementation. Mortality rates decreased from 45.4% to 14.2%, accompanied by a reduction in the intensive care unit (ICU) length of stay and an increase in the hospital length of stay. A comparison with international trauma centers highlights the importance of protocol-based management in improving the TBI outcomes and reducing the mortality—factors such as specialist-led care, institutional policies, and increased resources influenced guideline adherence and patient care. This study underscores the critical role of evidence-based guidelines in optimizing TBI management and emphasizes the need for their widespread implementation in clinical practice. In conclusion, this study demonstrates the substantial impact of BTF guidelines on enhancing TBI patient outcomes in a Saudi Arabian tertiary care center. The implementation of these guidelines resulted in a significant reduction in mortality and in an improved adherence to the best practices in TBI management, highlighting the importance of evidence-based protocols in optimizing patient care and outcomes.
