RESUMO
Objective To explore the efficacy and safety of dexmedetomidine combined with propofol on double-balloon enteroscopy.Methods Forty cases of patients ASA Ⅰ-Ⅱ grade who underwent double-balloon enteroscopy were divided into dexmedetomidine combined with propofol group (combine group) and propofol group by random digits table with 20 cases each group.Combine group was given load 0.7 μg/kg (intravenous infusion for 10 min) before induction and 0.2 μg/ (kg·h) continuous infusion during the surgery.All the patients were used propofol by target concentration with 2.5-4.0 mg/L for target-controlled infusion heart rate (H R),mean arterial pressure (MAP),respiratory rate (RR),peripheral oxygen saturation (SpO2) were recorded before examination(T0),eye lash reflex time(T1),during the perform (T2),the end of check (T3),sedation score,induction time,recovery time,total propofol amount,rates of adverse reaction and satisfaition were recorded.Results The induction time,recovery time was no statistically significant difference between two groups (P ＞ 0.05).The RR,SpO2 was no statistically significant difference between two groups at different time points (P ＞0.05).The HR at T1,T2 in combine group was significantly lower than that at T0 and in propofol group same period[(65.8 ± 7.3),(68.6 ± 8.2) times/min vs.(84.6 ± 7.1) and (77.6 ± 7.2),(89.6 ± 8.4) times/min,P ＜ 0.05].The MAP at T1 in combine group was significantly higher than that at T0 and in propofol group same period [(88.9 ± 9.4) mm Hg (1 mm Hg =0.133 kPa) vs.(81.3 ± 4.5) and (73.5 ± 6.8) mm Hg,P ＜ 0.05],at T2 was significantly lower than that in propofol group [(80.6±6.6) mm Hgvs.(88.5 ±7.6) mm Hg,P＜0.05].Sedation score 1 score 18 cases,2 scores 2 cases in combine group; 1 score 3 cases,2 scores 17 cases in propofol group,the difference was statistically significant (P ＜ 0.05).Combine group apnea two cases,moving,choking three cases,propofol group were eight cases and seven cases,the difference was statistically significant (P ＜ 0.05).The total propofol amount in combine group was significantly lower than that in propofol group [(421 ± 76) mg vs.(638 ± 89) mg,P ＜ 0.05].Conclusion Dexmedetomidine composite target controlled infusion of propofol used for double-balloon enteroscopy can produce good narcotic analgesic which is safe and effective anesthesia.
RESUMO
@#To study the effects of rCBF and brain function in the patients with cerebral infarction byearly rehabilitation training. 89 cases were randomized into rehabilitation and control groups and were ex-amined rCBF by 133Xe inhalation method and BEAM. Total effect rate was 93.9%in rehabilitationgroup,to the control 77.5%(X2=3. 95,P<0.05). The rCBF rised up in two groups,but it was higher inthe foriner,to the contro1,t=4. 99,P<0. 01. BEAM improve rate was 95.9%,to the control,77.5%(X2=5. 30,P<0. 05). So we confirmed that early rehabilitation training may promote rCBF and improve brainfunction of patients with cerebral infarction.
