Abstract

Background:

There are many published studies about loss of consciousness related to general trauma however works on loss of consciousness in respect to orthopedic injuries are scarce.

Aim:

The aim of this study was to investigate whether loss of consciousness worsens the prognosis of patients with orthopedic injuries.

Method:

A retrospective cohort study of orthopedic traumas was performed in the university Hospital of Base in São José do Rio Preto. All accident victims with injuries of the extremities classified as Score 3 or 4 by the Abbreviated Injury Scale (AIS) were included in this observational quantitative study. Patients with minor injuries and injuries that did not involve the extremities were not included. The association of loss of consciousness at the scene of the accident with evolution to death was investigated. The t-test, chi-squared and Fisher exact tests, and relative risk were used for statistical analysis. An alpha error of 5% (p-value ≤ 0.05) was considered statistically significant.

Results:

A total of 245 patients with ages between 13 and 98 years old and a mean of 45.4 years had extremity AIS scores of 3 or 4. Of these, significantly more men (170 - p< 0.001) suffered this type of injury than women (71). Thirty-six (14.94%) of these patients lost consciousness compared to 205 (85.06%) who did not lose consciousness. The total death rate in this group of patients was 5.39%; 9 (25%) of the 36 patients who lost consciousness and 4 (1.95%) of the 205 who did not lose consciousness died (Fisher exact test: p-value = 0.0001 and relative risk = 12,813 – 95% confidence index: 4,166 to 39,408).

Conclusion:

Loss of consciousness in patients with orthopedic injuries of the extremities is associated to a higher death rate.

Keywords: Injuries of the extremity, trauma, loss of consciousness.

"It is important that students and researchers from all over the world can have easy access to relevant, high-standard and timely scientific information. This is exactly what Open Access Journals provide and this is the reason why I support this endeavor."


Jacques Descotes
(Centre Antipoison-Centre de Pharmacovigilance, France)

"Publishing research articles is the key for future scientific progress. Open Access publishing is therefore of utmost importance for wider dissemination of information, and will help serving the best interest of the scientific community."


Patrice Talaga
(UCB S.A., Belgium)

"Open access journals are a novel concept in the medical literature. They offer accessible information to a wide variety of individuals, including physicians, medical students, clinical investigators, and the general public. They are an outstanding source of medical and scientific information."


Jeffrey M. Weinberg
(St. Luke's-Roosevelt Hospital Center, USA)

"Open access journals are extremely useful for graduate students, investigators and all other interested persons to read important scientific articles and subscribe scientific journals. Indeed, the research articles span a wide range of area and of high quality. This is specially a must for researchers belonging to institutions with limited library facility and funding to subscribe scientific journals."


Debomoy K. Lahiri
(Indiana University School of Medicine, USA)

"Open access journals represent a major break-through in publishing. They provide easy access to the latest research on a wide variety of issues. Relevant and timely articles are made available in a fraction of the time taken by more conventional publishers. Articles are of uniformly high quality and written by the world's leading authorities."


Robert Looney
(Naval Postgraduate School, USA)

"Open access journals have transformed the way scientific data is published and disseminated: particularly, whilst ensuring a high quality standard and transparency in the editorial process, they have increased the access to the scientific literature by those researchers that have limited library support or that are working on small budgets."


Richard Reithinger
