Abstract:
Objective To evaluate the effect of intraoperative application of dexmedetomidine on acute post-traumatic stress disorder (PTSD) in female patients with lower limb fracture.Methods Ninety female patients with lower limb fractures caused by traffic accident,of American Society of Anesthesiologists physical status Ⅰ or Ⅱ,aged 20-35 yr,weighing 40-72 kg,scheduled for elective internal fixation,were divided into 3 groups (n =30 each) using a random number table:control group (group C),low-dose dexmedetomidine group (group D1) and high-dose dexmedetomidine group (group D2).Ropivacaine (0.75％) 10-15 ml was injected into the epidural space,and operation was started after pain disappeared at the plane T8-10.Two percent lidocaine 5-10 ml was intermittently injected to maintain the anesthetic plane at T10.After successful epidural anesthesia,dexmedetomidine 0.5 and 1.0 μg/kg were intravenously infused over 30 min in D1 and D2 groups,respectively,while the equal volume of normal saline was given in group C.Patient-controlled epidural analgesia was performed with 0.15％ ropivacaine after operation and lasted until 48 h postoperatively,maintaining visual analogue scale score ≤ 3 (baseline).Morphine 3 mg was intravenously injected for rescue analgesia when visual analogue scale score＞3.The requirement for rescue analgesia within 48 h after operation was recorded.Acute Stress Disorder Scale (ASDS),Self-Rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) scores were assessed at 1 h before operation and on 1,3 and 7 days after operation.The patients were followed up for 3 months by telephone,and the PTSD Checklist-Civilian Version score was evaluated.The occurrence of acute PTSD (PTSD Checklist-Civilian Version score ＞ 38) was recorded.Results Compared with group C,the ASDS,SAS and SDS scores were significantly decreased on 1,3 and 7 days after operation,and the incidence of acute PTSD was decreased in D1 and D2 groups (P＜0.05).Compared with group D1,the ASDS scores were significantly decreased on 1,3 and 7 days after operation,and the incidence of acute PTSD was decreased (P＜0.05),and no significant change was found in SAS or SDS scores at each time point in group D2 (P＞ 0.05).There was no significant difference in the requirement for rescue analgesia between the three groups (P＞0.05).Conclusion Intraoperative application of dexmedetomidine can reduce the occurrence of acute PTSD and it is dose-related in female patients.
