China Pharmacist 2017;20(2):281-284
Objective:To compare the preventive effects of dezocine or parecoxib used alone or combination on emergence pain and agitation in the patients undergoing radical hysterectomy. Methods: Sixty ASA Ⅰ~Ⅱ patients undergoing radical hysterectomy were randomly divided into three groups. At the time of sewing incision, the dezocine group (group D, n=20) received dezocine in-travenous injection at the dosage of 0. 1 mg·kg-1, the parecoxib group (group P, n=20) received parecoxib intravenous injection at the dosage of 0.8 mg·kg-1, and the combination group (group DP, n=20) received 0.1 mg·kg-1dezocine and 0.8 mg·kg-1 parecoxib. When the operation was finished, the patients were transferred to the recovery room with endotracheal tubes, and recovered and extubated without the administration of reversal agents. Visual analogue scale ( VAS) for pain and Aono' s four-point scale for e-mergence agitation ( EA) were measured. The recovery time, extubation time, VAS, degree of EA and side effects such as nausea, vomiting, respiratory depression and hypersomnia during the emergence were also evaluated and recorded. Results:There were no sig-nificant differences in recovery time and extubation time among the three groups (P >0. 05). The VAS score and degree of EA in group DP were lower than that in group D (4. 65 ± 1. 69) and group P (5. 95 ± 1. 82) (P<0. 05), and the VAS score in group D was lower than that in group P (P<0. 05). The incidence of moderate and severe pain during the emergence in group DP (20%) was low-er than that in group D and group P (75% and 85%, respectively, P<0. 05), and that was lower in group D when compared with that in group P(P<0. 05). There were no significant differences in the incidence of degree of EA higher than 3 among the three groups (P>0. 05), and no side effects such as nausea, vomiting, respiratory depression and hypersomnia were detected during the emergence. Conclusion:Intravenous injection of 0. 1 mg·kg-1 dezocine combined with 0. 8 mg·kg-1 parecoxib at the time of sewing incision shows effective analgesia and emergence agitation reduction without obvious complications in the patients undergoing radical hysterecto-my.

AIM: To investigate the function of matrix metalloproteinase-3 (MMP-3) and urokinase-type plasminogen activator receptor (uPAR) to macroangiopathy in type 2 diabetes mellitus. METHODS: The levels of MMP-3 and uPAR in plasma were determined by ELISA sandwich method in 26 healthy controls and 39 patients with type 2 diabetes mellitus including 15 complication-free cases and 24 with macroangiopathy. RESULTS: The plasma level of uPAR but not MMP-3 was higher in patients without macroangiopathy than that in normal controls (P

Objective To compare the development of gastric insufflation related to different peak inspiratory pressures (PIPs) during facemask ventilation in the pediatric patients.Methods Ninety male pediatric patients,aged 2-4 yr,of American Society of Anesthesiologists physical status Ⅰ,scheduled for elective surgery under general anesthesia,were randomly divided into 5 groups (n =18 each) using a random number table:PIP 8 cmH2O group (group P8),PIP 10 cmH2O group (group P10),PIP 12 cm H2O group (groupP12),PIP 14cmH2O group (group P14) and PIP 16 cmH2O group (group P16).Anesthesia was induced with fentanil,propofol and rocuronium in sequence.After loss of eyelash reflex,positive pressure facemask ventilation was performed for a 120 s period in pressure-controlled mode.Gastric insufflation was detected by real-time ultrasonography of the antrum,and cross-sectional antral area was measured using ultrasonography before facemask ventilation and at 120 s of facemask ventilation.The pulse oximetry (SpO2),tidal volume (VT),end-tidal pressure of carbon dioxide (PETCO2) and end-tidal oxygen concentration (ETO2) were recorded at 30,60,90,and 120 s of facemask ventilation.The development of gastric insufflation and hypoventilation was recorded.Results Compared with group P8,the incidence of gastric insufflation was significantly increased in group P16 (P<0.01),and no significant change was found in the incidence of gastric insufflation in the other groups (P>0.05),the incidence of hypoventilation was significantly decreased,VT and ETO2 were increased,and PET CO2 was decreased in P12,P14 and P16 groups,and PETCO2 was significantly decreased at 120 s of facemask ventilation (P< 0.05 or 0.01),and no significant change was found in the other parameters in group P10 (P>0.05).Compared with P12 and P14 groups,VT was significantly increased,PEHTCO2 was decreased at 120 s of facemask ventilation (P<0.05),and no significant change was found in the incidence of hypoventilation and ETO2 in group P16 (P>0.05).There was no significant difference between group P12 and group P14 in the incidence of hypoventilation,VT,PETCO2 and ETO2 (P>0.05).The pediatric patients showed a certain CO2 accumulation [PETCO2 (40.6±4.0) mmHg] at 120 s of facemask ventilation in group P8,and the pediatric patients showed excessive ventilation [PETCO2 (23.6± 1.4) mmHg],and cross-sectional antral area was not measured using ultrasonography in three cases because of excessive gastric insufflation in group P16.Conclusion PIP at 12-14 mmHg in pressure-controlled ventilation mode can not only ensure adequate preoxygenation and but also avoid excessive gastric insufflation during facemask ventilation in the pediatric patients.

Induced current electrical impedance tomography (ICEIT) is a new branch of electrical impedance tomography (EIT). We have designed and set up a high accuracy ICEIT hardware system with 32 electrodes based on physical phantom, and we have brought forward a new method to reduce the additive electromotive force (EMF) in circuit of the electrode leads. By use of the technique of twisted pair wire, the additive EMF in the circuit of the electrode leads has been reduced to 10% of that before use and the precision of the system has been improved. The precision of the final results is better than 0.5% after 1000 measurement data averaged. Applying the reconstructive algorithm, we have obtained preliminary images based on physical phantom.
