Abstract:
Objective:To evaluate the effect of patient-controlled intravenous analgesia (PCIA) with dexmedetomidine mixed with subanesthetic dose of ketamine on anxiety and depression in the patients with advanced cancer pain.Methods:Sixty patients of either gender with advanced cancer pain, aged 24-82 yr, with poor analgesic effect or obvious adverse reactions after three-step analgesic treatment, were selected and randomly divided into 2 groups ( n=30 each) using a random number table method: routine treatment group (group R) and dexmedetomidine mixed with ketamine group (group DK). The initial dose of morphine for PCIA was 1/3 of the oral dose in group R. In group DK, ketamine 5.4 mg/kg (90 μg·kg -1·h -1) and dexmedetomidine 6 μg/kg (0.1 μg·kg -1·h -1) were added on the basis of group R. Tropisetron 8 mg was added to analgesics and diluted to 200 ml with normal saline in both groups.The analgesic pump was programmed to deliver 4 ml with an initial dose of 4 ml, lockout interval of 15 min and background infusion at 4 ml/h.The numerical rating scale score, Ramsay sedation score, Chinese version of State-Trait Anxiety Inventory score and Beck Depression Inventory-Ⅱ score were recorded before PCIA and at 4, 12, 24 and 48 h of PCIA.The development of effective analgesia and satisfactory sedation, occurrence and degree of depression, score for patient's quality of life and satisfaction score, consumption of morphine and adverse reactions such as constipation, nausea and vomiting, agitation and respiratory depression were recorded within 48 h of PCIA. Results:Compared with group R, the NRS score was significantly decreased, the rate of effective analgesia was increased, Beck Depression Inventory-Ⅱscore and Chinese version of State-Trait Anxiety Inventory score were decreased, the incidence and degree of depression were decreased, incidence of nausea and vomiting and constipation, consumption of morphine and pressing times of PCIA pump were decreased, and the score for patient's quality of life and satisfaction score were increased in group DK ( P<0.05). Conclusion:PCIA with dexmedetomidine mixed with subanesthetic dose of ketamine can significantly enhance the analgesic effect, improve anxiety and depression, and raise the quality of life when used for the patients with advanced cancer pain.
