ABSTRACT

ObjectiveTo study the clinical efficacy and safety of Narcotrend (NT) monitor for the prevention of awareness during general anesthesia.MethodsFour hundred and thirty-two patients with elective extubation and general anesthesia (ASA Ⅰ-Ⅱ) were divided into observation group and control group with 216 cases each by random digits table.All patients were treated with total intravenous anesthesia.The patients were given anesthetics by NT monitor in observation group and detemined by the clinical experience of anesthesiologists in control group.The mean arterial pressure (MAP),heart rate (HR),respiratory rate(RR),pulse oxygen saturation(SpO2),NT stages (NTS),NT index (NTI),total sedatives,awaking time,extubation time,Ramsay score was recorded.All patients in the postoperative on the first day and the fourth day were followed-up two times to understand the perception and memory in patients undergoing the situation.ResultsThere was no know in operation in observation group,there was 1 case with suspectedknow and 1 case with definite know in control group.Compared with control group,the awaking time and extubation time was decreased in observation group [ ( 6.0 ± 2.8 ) min vs.( 10.0 ± 4.9 ) min,( 12.0 ± 5.5 ) min vs.( 19.0 ± 6.9) min] (P < 0.05 ); MAP and HR was even more stable.In addition to midasolam,the remaining amount of the drug was less (P < 0.05 ).Ramsay score at awaking,extubation and out of the operating room in observation group was lower than that in control group (P < 0.05).ConclusionNT monitor for total intravenous anesthesia increases the safety of general anesthesia,and it can be reduced to some extent,intraoperative awareness.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate whether pretreatment with repeated electroacupuncture (EA) at the Baihui acupoint could induce ischemic tolerance against transient focal cerebral ischemic injury in rats.</p><p><b>METHODS</b>Thirty male Sprague-Dawley (SD) rats were randomly divided into 3 groups (n=10 for each): the control group consisted of animals receiving no treatment, the isoflurane (ISO) group had animals that inhaled 1.5% isoflurane for 30 min a day for 5 days, and animals in the EA group received electroacupuncture at the Baihui acupoint for 30 min a day for 5 days under 1.5% isoflurane anesthesia. Twenty-four hours after the last treatment, the middle cerebral artery was occluded with No. 3 nylon monofilament for 120 min. The neurological outcomes were evaluated 24 h after reperfusion. The infarct volumes were then assessed using 2% triphenyltetrazolium chloride staining after the neurological outcome evaluation.</p><p><b>RESULTS</b>The neurological deficit score (NDS) of the EA group [1 (0-2)] was lower than that of the ISO group [2 (1-3)] and the control group [2 (1-4)], P < 0.05. The infarct volume of the EA group (38.3 +/- 25.4 mm(3)) was significantly smaller than that of the control group (220.5 +/- 66.0 mm(3)) and the ISO group (168.6 +/- 57.6 mm(3)) 24 h after reperfusion.</p><p><b>CONCLUSION</b>Electroacupuncture at the Baihui acupoint 30 min a day for 5 days significantly reduces neurological injury induced by transient middle cerebral artery occlusion.</p>

ABSTRACT

OBJECTIVE:To evaluate the clinical effects of urapidil on cardiovascular response induced by sympathetic stimulation during front approach cervical vertebra operation.METHODS:One hundred and twenty patients undergoing front approach cervical vertebra operation were randomly divided into three groups.Patients in URA group treated with0.5mg/kg urapidil and patients in NIC group treated with5?g/kg nicardipine when systolic blood pressure(SBP)and heart rate(HR)increased by sympathetic nerve stimulation during the operation.And patients in COM group only increased their anesthesia degree with isoflurane at the same situation.The patients’SBP and HR were observed and compared among three groups at the time before the sympathetic nerve stimulation,and5minutes and10minutes after the drugs treatment respective?ly.RESULTS:The patients’SBP and HR in URA group had no significantly increase after administration of urapidil.In NIC group,although the patients’SBP had no significantly increase,the patients’HR increased significantly after nicardipine was used.But the patients’SBP and HR increased significantly after improved anesthesia degree with isoflurane.CONCLUSION:Urapidil has better effect on sympathetic cardiovascular response during the front approach cervical vertebra operation com?pared with nicardipine.
