Abstract:
Objective To explore the efficacy and safety of low-dose ketamine for prevention of shivering during cesarean section under subarachnoid space and epidural anesthesia.Methods Ninety pregnant women who scheduled cesarean delivery under subarachnoid space and epidural anesthesia were randomized divided into three groups:control group (30 patients) low-dose ketamine group (30 patients) and high-dose ketamine group (30 patients).0.9％ sodium chloride,0.25 mg/kg(3 ml),and 0.50 mg/kg (3 ml) ketamine were given in three groups before operation.The incidence of shivering and adverse effect were recorded respectively before anesthesia,after anesthesia 15 min and 30 min and after operation 1 h.Results The level of mean arterial pressure (MAP) in control group after anesthesia 15 main and 30 min and after operation 1 h[(62 ± 10),(58 ± 8),(61 ± 11) mm Hg(1 mm Hg =0.133 kPa)] were significantly lower than those in high-dose ketamine group [(78 ± 12),(82 ± 8),(76 ± 11)mm Hg] and low-dose ketamine group [(72 ± 10),(76 ± 6),(80 ± 7) mm Hg],there was significant difference (P ＜ 0.05).There was no shivering need treat in low-dose ketamine group and high-dose ketamine group.The rate of hallucinations and nystagmus in low-dose ketamine group [0,6.7％ (2/30)] was significantly lower than that in high-dose ketamine group [20.0％ (6/30),50.0％ (15/30)],there was significant difference (P ＜ 0.05).Conclusion The pretreatment with low-dose ketamine on shivering during cesarean section under subarachnoid space and epidural anesthesia has better preventive effectiveness,0.25 mg/kg of ketamine is more effective than 0.50mg/kg.
