Effect of psychosocial nursing intervention on analgesic efficacy of labour analgesia in parturients / 中华麻醉学杂志

ABSTRACT

Objective To evaluate the effect of psychosocial nursing intervention on the analgesic efficacy of labour analgesia in parturients.Methods A total of 160 parturients,aged 18-35 yr,with a singleton fetus in vertex presentation at 38-41 week gestation,who required labor analgesia voluntarily,were divided into 2 groups (n =80 each) using a random number tablecontrol group (group C) and psychosocial nursing intervention group (group Ⅰ).The epidural catheter was placed at L2.3 interspace when the cervical dilation was 3 cm,and 0.1％ ropivacaine 12 ml was injected.And then patient-controlled epidural analgesia (PCEA) was performed.The solution for PCEA contained 0.1％ ropivacaine and hydromorphone hydrochlorid 2.5 μg/ml (diluted to 160 ml in 0.9％ normal saline).The catheter was connected to a PCEA pump programmed to deliver 6 ml with a lockout interval of 12 min,background infusion at 0.1 ml/h and limit dose of 30 ml/h.After the initial administration of ropivacaine,parturients were only informed of the usages and notice items of the PCEA pump in group C,and in addition psychological nursing intervention was carried out,and the peak effect of drugs and principle of PCEA pump were also introduced in group Ⅰ.The intensity of pain was assessed using visual analogue scale score before labour analgesia and at 15,30,60,120,180 and 240 min after labour analgesia.The development of adverse reactions such as lower extremity numbness,motor nerve block,nausea and vomiting,pruritus,urinary retention and hypotension after labour analgesia was recorded.Parturient's satisfaction with labour analgesia was evaluated at 24 h after the end of delivery,and the rate of satisfactory analgesia was calculated.Results Compared with group C,visual analogue scale scores were significantly decreased at 60,120,180 and 240 min after labour analgesia,and the rate of satisfactory analgesia was increased in group Ⅰ (P＜0.05).One patient developed motor nerve block at 30 min after labour analgesia in group C,and no patient developed motor nerve block after labour analgesia in group Ⅰ.No adverse reactions such as lower extremity numbness,nausea and vomiting,pruritus,urinary retention or hypotension were found in the two groups.Conclusion Psychosocial nursing intervention can raise the analgesic efficacy of labour analgesia in parturients.
