inflammatory medication can be administered. The tissue plasminogen activator has been effective in maintaining perfusion and decreasing the need for amputation when administered within 24 hours of rewarming
A 30-week pregnant trauma patient's vital signs include a blood pressure of 94/62 mm Hg and a heart rate of 108 beats/minute. Fetal heart tones are 124 beats/minute.
