ABSTRACT
Objective To compare the effects of sedation induced with propofol and midazolam on anterior pituitary hormone in mechanically ventilated patients with traumatic brain injury.Methods Eighty-four patients with acute traumatic brain injury,aged 20-60 yr,weighing 50-70 kg,undergoing mechanical ventilation during sedation induced with propofol or midazolam,were randomly divided into 2 groups ( n =42 each)propofol group (group P) and midasolam group (group M).Ramsay sedation score was maintained at 2-4.In group P,propofol was continuously infused at the initial infusion rate of 1.5-6.0 mg·kg-1 ·h-1 and propofol 50 mg was injected intravenously to increase the depth of sedation when needed.In group M,midazolam was continuously infused at the initial infusion rate of 0.10-0.35 mg· kg-1· h-1 and midazolam 7.5 mg was injected intravenously to increase the depth of sedation when needed.The patients were ventilated for 70-120 h.Glasgow Coma Scale scores were assessed before sedation and Glasgow Outcome Scale scores were assessed 4 weeks after admission to the intensive care unit.Venous blood samples were collected at 24 and 72 h of sedation and 4 weeks after admission to the intensive care unit for determination of the levels of serum cortisol,thyroid-stimulating hormone,prolactin,and growth hormone by ELLSA.Results Compared with group M,the levels of serum cortisol and growth hormone were significantly decreased and the level of thyroid-stimulating hormone was significantly increased at 24 and 72 h of sedation in group P ( P < 0.05 or 0.01 ),and the parameters mentioned above were in the normal range.There was no significant difference in the serum prolactin level and outcome between the two groups (P > 0.05).Conclusion The effects of sedation induced with propofol and midazolam on anterior pituitary hormone are comparable in mechanically ventilated patients with traumatic brain injury.
