[Fluid resuscitation in traumatic shock].

OBJECTIVE: To investigate fluid resuscitation affecting the result of treatment of patients with traumatic shock. METHODS: Two hundred and fifty-six cases of patients with traumatic shock treated in our hospital between January 1989 and December 2002 were analysed retrospectively, and the volume-effect relationship between fluid resuscitation during the first hour and future of traumatic shock was summarised. RESULTS: The successful rate of resuscitation was 73.05 percent (187 cases), and traumatic mortality was 26.95 percent (69 cases). After 1-hour trauma, the survival rate was 52.27 percent in patients with 1 liter of resuscitation fluid, 75.90 percent in patients with 15-20 liter of resuscitation fluid, and 78.29 percent of more than 20 liter resuscitation fluid, 86.79 percent in mild shock, 80.34 percent in middle shock and 54.65 percent in severe shock. CONCLUSION: Severe trauma and shock, hypotension and incorrect resuscitation manipulation are the main factors affecting the result of resuscitation and treatment of traumatic shock. It is important to early and correctly expand, especially at the first hour. The aim of resuscitation of traumatic shock is to maintain the hemodynamics and correct O2 defect.

[A tentative research of testosterone supplement therapy on male senile dementia].

OBJECTIVES: To understand the hormone levels in male senile dementia patients and the effects of testosterone supplement theraphy (TST) on male senile dementia. METHODS: The general health condition, mental health condition, hormone levels, and some other aspects were evaluated in 9 patients with male senile dementia without significant contradiction for TST. 9 patients were treated with oral testosterone undecanoate 120 mg per day for six weeks, and relative changes were observed, detected and recorded. RESULTS: In 9 cases of male senile dementia, the average score was 5.33 in mini-mental state examination (MMSE), 14.56 in Hamilton depression scale (HAMD), 5.0 in geriatric depression scale (GDS), 32.56 in partial androgen deficiency of the aging male (PADAM) measuring form. The volume of testis was small (8.33 ml on average). After 1 week of having finished TST, the levels of serum testosterone (T) dropped significantly (dropped from average 2.88 ng/ml to 2.47 ng/ml, P < 0.05) in 9 patients with TST. General evaluation with clinician's global impression(CGI) for 9 patients showed 2 cases fail and 7 cases with progress (3 of them progress significantly). Average score dropped in HAMD form (10.67) and PADAM form (28.11). Physical strength and psychological status improved significantly, but vasomotor symptoms and sexual function failed response to the treatment. CONCLUSIONS: The levels of androgen is low, and the symptoms of androgen deficiency are readily seen in male senile dementia. TST can improve life quality of most patients to some extent.
