Home-related falls: An underestimated mechanism of injury

BACKGROUND:

The home is a leading location for falls, but the epidemiology and outcome of falls at home (FH) have not been adequately described. Our aim was to evaluate FH, particularly in the bathroom.

MATERIALS AND METHODS:

We conducted a retrospective analysis of patients with a history of FH admitted to the Level I trauma center in Qatar. Patients were divided into Group 1: <60 years and Group 2: 60 year or older, and their data were analyzed and compared.

RESULTS:

A total of 98 patients with FH in the bathroom with a mean age of 51 ± 18 years, mostly males (73.5%) were identified over 3 years. One out of every 50 trauma patients admitted was a victim of a fall in the bathroom. Group 2 had significantly more females and sustained a single-site injury. Group 1 had more involvement of alcohol (P = 0.02) and sustained more multiple injuries (44% vs. 23%; P = 0.02). The mean Injury Severity Score and length of hospital stay was comparable among the two groups. Head, abdomen, and facial injuries were significantly higher in Group 1 whereas lower extremity injuries and mortality were significantly higher in Group 2.

CONCLUSION:

FH, particularly in the bathroom, is an underrecognized mechanism of injury with a unique dichotomous epidemiology based on age. This needs increased public awareness and primary prevention programs for high-risk populations.

False negative pericardial Focused Assessment with Sonography for Trauma examination following cardiac rupture from blunt thoracic trauma: a case report

INTRODUCTION

The Focused Assessment with Sonography for Trauma examination is an invaluable tool in the initial assessment of any injured patient. Although highly sensitive and accurate for identifying hemoperitoneum, occasional false negative results do occur in select scenarios. We present a previously unreported case of survival following blunt cardiac rupture with associated negative pericardial window due to a concurrent pericardial wall laceration.

CASE PRESENTATION

A healthy 46-year-old white woman presented to our level 1 trauma center with hemodynamic instability following a motor vehicle collision. Although her abdominal Focused Assessment with Sonography for Trauma windows were positive for fluid, her pericardial window was negative. After immediate transfer to the operating room in the setting of persistent instability, a subsequent thoracotomy identified a blunt cardiac rupture that was draining into the ipsilateral pleural space via an adjacent tear in the pericardium. The cardiac injury was controlled with digital pressure, resuscitation completed, and then repaired using standard cardiorrhaphy techniques. Following repair of her injuries (left ventricle, left atrial appendage, and liver), her postoperative course was uneventful.

CONCLUSIONS

Evaluation of the pericardial space using Focused Assessment with Sonography for Trauma is an important component in the initial assessment of the severely injured patient. Even in cases of blunt mechanisms however, clinicians must be wary of occasional false negative pericardial ultrasound evaluations secondary to a concomitant pericardial laceration and subsequent decompression of hemorrhage from the cardiac rupture into the ipsilateral pleural space.

Dilemma of Blunt Bowel Injury: What are the Factors Affecting Early Diagnosis and Outcomes

Blunt bowel and mesenteric injury (BBMI) is frequently a difficult diagnosis at initial presentation. We aimed to study the predictors for early diagnosis and outcomes in patients with BBMI. Data were collected retrospectively from the database registry between January 2008 and December 2011 in the only Level I trauma unit in Qatar. Patients with BBMI were divided into Group A (surgically treated within 8 hours) and Group B (treated after 8 hours). Data were analyzed and χ2, Student's t test, and multivariate regression analysis were performed appropriately. Among 984 patients admitted with blunt abdominal trauma (BAT), 11 per cent had BBMI with mean age of 35 ± 9.5 years. Polytrauma and isolated bowel injury were identified in 53 and 42 per cent, respectively. Mean Injury Severity Score (ISS) was higher in Group A in comparison to Group B (18 ± 11 vs 13 ± 8; P = 0.02). Presence of pain and seatbelt sign ( P = 0.02) were evident in Group B. Hypotension ( P = 0.004) and hypothermia ( P = 0.01) were prominent in Group A. The rate of positive Focused Assessment Sonography for Trauma was greater in Group A ( P = 0.001). Among operative findings, bowel perforation was more frequent in Group B ( P = 0.04), whereas mesenteric full-thickness hematoma was significantly higher in Group A. Pelvic fracture was more frequent finding in Group A ( P = 0.005). The overall mortality rate was 15.6 per cent. In patients with BAT, the presence of abdominal pain, hypotension, ISS greater than 16, hypothermia, pelvic fracture, and mesenteric hematoma might help in early diagnosis of BBMI. Moreover, base deficit and mean ISS were independent predictors of mortality. Delayed operative interventions greater than 8 hours increased morbidity rate but had no significant impact on mortality.

Concurrent rib and pelvic fractures as an indicator of solid abdominal organ injury

OBJECTIVES

To study the association of solid organ injuries (SOIs) in patients with concurrent rib and pelvic fractures.

METHODS

Retrospective analysis of prospectively collected data from November 2007 to May 2010. Patients' demographics, mechanism of injury, Injury severity scoring, pelvic fracture, and SOIs were analyzed. Patients with SOIs were compared in rib fractures with and without pelvic fracture.

RESULTS

The study included 829 patients (460 with rib fractures ± pelvic fracture and 369 with pelvic fracture alone) with mean age of 35 ± 12.7 years. Motor vehicle crashes (45%) and falls from height (30%) were the most common mechanism of injury. The overall incidence of SOIs in this study was 22% (185/829). Further, 15% of patient with rib fractures had associated pelvic fracture. SOI was predominant in patients with concurrent rib fracture and pelvic fracture compared to ribs or pelvic fractures alone (42% vs. 26% vs. 15%, respectively, p = 0.02).

CONCLUSIONS

Concurrent multiple rib fractures and pelvic fracture increases the risk of SOI compared to either group alone. Lower RFs and pelvic fracture had higher association for SOI and could be used as an early indicator of the presence of SOIs.

Rib Fracture Patterns Predict Thoracic Chest Wall and Abdominal Solid Organ Injury

Blunt trauma patients with rib fractures were studied to determine whether the number of rib fractures or their patterns were more predictive of abdominal solid organ injury and/or other thoracic trauma. Rib fractures were characterized as upper zone (ribs 1 to 4), midzone (ribs 5 to 8), and lower zone (ribs 9 to 12). Findings of sternal and scapular fractures, pulmonary contusions, and solid organ injures (liver, spleen, kidney) were characterized by the total number and predominant zone of ribs fractured. There were 296 men and 14 women. There were 38 patients with scapular fracture and 19 patients with sternal fractures. There were 90 patients with 116 solid organ injuries: liver (n = 42), kidney (n = 27), and spleen (n = 47). Lower rib fractures, whether zone-limited or overlapping, were highly predictive of solid organ injury when compared with upper and midzones. Scapular and sternal fractures were more common with upper zone fractures and pulmonary contusions increased with the number of fractured ribs. Multiple rib fractures involving the lower ribs have a high association with solid organ injury, 51 per cent in this series. The increasing number of rib fractures enhanced the likelihood of other chest wall and pulmonary injuries but did not affect the incidence of solid organ injury.
