Abstract:
ObjectiveTo investigate the effect of patient-controlled epidural analgesia(PCEA) with opioids on serous myelin basic protein(MBP) and somatosensory evoked potential(SEP) of lower limbs in puerperants.MethodsA total of 120 puerperants,after receiving cesarean section,were divided into four groups by random number table method as group B,BR,MR and R randomly,and each group included 30 cases.After surgery,each case received PCEA:group B received 0.008% butrophanol;group BR received 0.008% butrophanol + 0.2% ropivacaine;group MR received 0.004% morphine +0.2% ropivacaine and group R received 0.2% ropivacaine only.VAS score,OAA/S score,adverse effect occurrence,concentration changes of serous MBP,SEP of both lower limbs and neurological function were observed at 2h(T1 ),4h(T2),8 h(T3),12h(T4),24 h(T5) and 48h (T6) after surgery.ResultsVASscoresofgroupBR(1.64±0.38,1.86±0.62,1.93±0.67) and MR( 1.74 ±0.39,1.91±0.58,1.98 ±0.63) at T3,T4,T5 were lower than those of group B(4.6 ±0.5,4.6 ±0.3,4.7 ±0.3)and R(2.64 ±0.41,2.83 ±0.91,3.37 ±0.87) (P<0.05).There was no significance in four groups in OAA/S score at each point (P > 0.05 ).Incidence of nausea ( 6 cases),vomiting ( 2 cases) and abdominal distention ( 5cases) of group M was higher than that of other three groups(P<0.05).There was no significant difference in concentrations of serous MBP,SEP and neurological function in all four groups between preoperative time and 48h after operation(P>0.05).ConclusionLower-dose and lower- concentration opioids used for PCEA have no influence on serum MBP and SEP.
