Journal of Medical Research.2009;38(8):113-115.

Objective To investigate the regulation effect of bispectral index (BIS) on the depth of total intravenous anesthesia (TI-VA) by comparing with regulating the depth of anesthesia according to the changes of hemodynamics. Methods 60 ASA Ⅰ～Ⅱ patients undergoing laparoscopic cholecystectomy (LC) were randomly assigned into controlled group (group C) and trial group (group T) ,with 30 patients in each group, according to the rules of regulating the titration of propofol during TIVA. The target of group C was to keep SBP/DBP 100 ～ 140mmHg/60 ～ 89mmHg and that of group T was to keep BIS 40 ～ 60 during anesthesia. The measure indexes included SBP/DBP, HR, BIS, total dosis of Propofol, time to extubate, time to leave operating room and OAA/S (observer's assessment of alert-ness/sedation). After operation, we evaluated whether awareness during surgery happens. Results As compared with group C, there were higher SBP/DBP and BIS in group T after induction of anesthesia, during aeroperitonia, immediately after finishing operation and just before extubating endotracheal catheter, but less dosis of propofol and less time of extubation and leaving operating room in group T. The differences had significance (P <0.01). There were no significant differences in the changes of HR between two groups (P >0.05) and no awareness during surgery happened in both groups. Conclusion TIVA regulated by BIS during LC can decrease the dosis of propofol, accelerate the recovery from anesthesia and avoid extremely deep anesthesia and awareness during surgery.

Journal of Medical Research.2009;38(8):55-57.

Objective To study the clinical application and its impact factors of tidal flow - volume measurement in infants with bronchiolitis and pneumonia. Methods Thirty infants with bronchiolitis and thirty infants with pneumonia were studied. Tidal breathing flow- volume loops were obtained after the patients were sedated. The tidal volume per kilogram(VT/kg) ,the fraction of tidal volume ex-heled at peak tidal expiratory flow (PTEF) to total tidal volume (VPTEF/VE), and the fraction of exhaled time at PTEF to total expirato-ry time (TPTEF/TE) were measured. Results VT/kg was not significant different between the bronehiolitis group and the pneumonia group. VPTEF/VE and TPTEF/TE were lower in the bronehiolitis group than those in the pneumonia group. Conclusion The measure-ment of tidal breathing flow - volume loops is a good technology, which would be helpful to evaluate airway obstruction in wheezing in-fants. The impact factors should be controlled during the measurement. Otherwise, the results would be affected.

Journal of Medical Research.2009;38(8):42-44.

Objective To study the changes of ventilatory function of young soldiers coming from different regions during cold - tol-erance training. Methods The recruited young soldiers were divided into 2 groups:Group Ⅰ (50 coming from the northern region)and group Ⅱ (50 coming from the southern region) . According to the new training outline of cold -tolerance in winter,their ventilatory func-tions were tested before training and 60 days after training. Ventilatory functions were compared between smoking and non - smoking sub-jects. Results 25% forced expiratory flow (FEF25%) , 50% forced expiratory flow (FEF50%) and 75% forced expiratory flow (FEF75 %) were significant different between two groups before the course of training (P < 0.05). After 60 days, ventilatory functions of two groups were improved significantly as compared with that before training (P <0.01 ,P <0.05). There was no significant difference in ventilatory between two groups after 60 days of training (P > 0.05). There was significant difference in partial small airway function be-tween smoking and non - smoking subjects. Conclusion Cold air could decline the small airway function of soldiers coming from south-ern region before training. Cold -tolerance training has significant influence on soldiers' ventilatory function. Long- term and heavy smok-ing could decline the small airway function.
