Objective:To investigate the effects of diluted volumes of intrathecal fentanyl on pruritus during labour analgesia.Methods:One hundred parturients were randomly assigned to one of four groups to receive intrathecal fentanyl 20 μg in either 1.5
2
2.5 ml or 3 ml diluted volumes via a combined spinal-epidural technique(n=25 patients in each group).The incidence and severity of pruritus and pain visual analogue scale(VAS)were assessed.The levels of reduced cold sensation and the occurrences of respiratory depression
fetal bradycardia
nausea
vomiting and hypotension were also recorded.Results:Compared with 1.5ml or 2 ml
3 ml diluted volume led to a decreased occurrence and severity of pruritus(P<0.05).No significant differences were found in VAS and the occurrences of side effects(P>0.05).Conclusion:Increasing diluted volumes of intrathecal fentanyl demonstrated a reduced incidence and severity of pruritus during labour analgesia.
