The effects of acute head injury or subarachnoid hemorrhage on the cardiovascular system (CVS) are well known, but data are lacking on the effects of acute spinal cord injury (SCI) on the CVS. The clip compression SCI rat model was used to measure changes in the mean systemic arterial pressure (mSAP), cardiac output (CO), heart rate (HR), total peripheral resistance (TPR), and central venous pressure (CVP) after SCI. Three groups of five animals each were anesthetized with chloralose-urethane: one group underwent only the surgical procedures including laminectomy, and the other two received either a 2.3- or 53.0-gm injury at the T1 spinal cord segment for 1 minute. ⋯ Thus the CVS showed two major alterations after severe SCI: post-traumatic hypotension, and a parallel decline in CO. There were no major changes in TPR, HR, or CVP, although HR ultimately declined. These findings suggest that the decline in CO was not entirely due to decreased sympathetic tone, but may also have resulted from direct myocardial injury, similar to that demonstrated after head injury or subarachnoid hemorrhage.

Hyperextension of the cervical spine in the elderly can cause retropharyngeal hematomas. We report this unusual cause of retropharyngeal hematoma in a 77-year-old women. The airway must be thoroughly evaluated in any such patient in whom this lesion is suspected.

In the past 5 years, 72 moribund patients have undergone resuscitative thoracotomy (RT) at the Medical University of South Carolina: 62 patients underwent the procedure before the adoption of a policy of mandatory rapid transport (scoop and run) for penetrating and unstable victims of trauma by our EMS system (Group I). Group II is comprised of ten patients who underwent RT following adoption of this policy. Resuscitation was successful in three patients in Group I (4.8%) and there were only two survivors (3.2%). ⋯ Only two patients in Group II (20%) lost their vital signs in transport and both died. Four patients in Group II (40%) suffered cardiac arrest after arrival at the hospital. Two of these patients (50%) were successfully resuscitated and one left the hospital (25%).(ABSTRACT TRUNCATED AT 250 WORDS)

Since the initial hour after injury is the most crucial time for trauma patients, resuscitation technique is of vital importance. Standardized courses for first-hour management (ATLAS) have been widely accepted. A teaching format based upon video recording of every resuscitation has been developed. ⋯ Over a 3-month period, average resuscitation time to definitive care decreased for age- and injury severity-matched patient groups cared for by one team. Resuscitations have become more efficient and adherence to assigned responsibilities better. Weekly review of resuscitation contributes to improved technique and trauma care.

Two young children suffered loss of vision in separate incidents following traumatic asphyxia. Visual loss secondary to trauma can occur from a variety of causes. ⋯ In children, visual impairment is easily missed unless the degree of handicap is severe. All children should have their fundi and visual acuity assessed before discharge following significant trauma, including all episodes of traumatic asphyxia.
