Objective To explore the prognostic factors in patients with acute respiratory failure due to chronic obstructive pulmonary disease (COPD) in EICU. Method Clinical data of 39 patients admitted to EICU from May 2005 to May 2007 were retrospectivley analyzed. Results In death group, the pulmonary artery pressure (PAP) ,creatinine (Cr) ,APACHE-Ⅱ score, and APACHE-Ⅲ score were increased (P < 0. 05) and ICU stays were prolonged (P < 0.05) ; Respiratory rate (RR) and Glasgow coma score (GCS) were decreased (P < 0.05). Conclusion PAP, Cr, APACHE-Ⅱ score,APACHE-Ⅲ score,RR and GCS predict the prognosis of the patients with acute respiratory failure due to chronic obstructive pulmonary disease.

The advantages of non-contact medical monitoring radar were introduced compared with the traditional medical monitoring devices. The state of art of three kinds of typical medical monitoring radar schemes over the past decade was reviewed. Researches on breathing and heartbeat signal extraction, isolation and clutter suppression algorithms were summarized. The advantages and disadvantages of these algorithms were also pointed out. The prospects of non-contact medical monitoring radar were explored finally.

40), the values of BIS, electromyogram (EMG), signal quality index (SQI), mean arterial pressure(MAP), and heart rate(HR) were recorded every minute for 5min, then additional vecuronium (0.05mg/kg) was administered, and the values of the parameters above mentioned were registered for the next 10min. Results BIS value decreased significantly 3 min after the administration of the additional vecuronium (P0.05). Conclusion A misleading BIS value may be caused by the decline of muscle relaxant during the maintenance stage of propofol/fentanyl anesthesia, which greatly influence the accuracy of BIS monitoring.

0.7?g/L (n=18) and group 2 ≤0.7?g/L (n=18). Propofol concentration, BIS, and AAI were compared between the two groups. Results The patients in group 2 had a significantly higher propofol concentration in plasma (2.70 mg/L) on awakening compared with that of the group 1 (2.08 mg/L) (P

Objective To compare the analgesic effect, adverse effects of patient-controlled epidural analgesia (PCEA) vs patient-controlled intravenous analgesia (PCIA) and their influences on stress response in thoracotomy patients. Methods 33 ASA I-II patients undergoing elective esophagectomy were randomly assigned to receive either morphine plus droperidol (Group PCIA, n=17) or morphine plus bupivacaine (Group PCEA, n=16) for 3 days postoperatively. Serum concentrations of cortisol, angiotensin Ⅱ (Ang Ⅱ), endothelin (ET) and blood glucose were measured before operation, at the end of the operation and on the next morning after operation. Pain scores with visual analogue scale (VAS) at rest, deep breathing and with cough, and adverse effects were also recorded. Results Blood glucose and cortisol were increased to similar levels in both groups at the end of the operation, but were much lower in Group PCEA postoperatively (P0.05). Pain scores with VAS were much lower in Group PCEA, especially when the patient was at deep breathing or during coughing (P

Objective To compare the analgesic and side effects of tramadol, buprenorphine and morphine in equipotent dosage in patient-controlled intravenous analgesia (PCIA). Methods 53 patients (ASA I-II) scheduled for upper abdominal surgery were randomly allocated to receive 10mg/ml tramadol (group T) or 0.03mg/ml buprenorphine (group B) or 1mg/ml morphine (group M) plus 0.1mg/ml droperidol. Baxter APII PCA pump was used to administer the different analgesic according to the model of LCP, with the amount of loading dose, continuous infusion and bolus of 2.5ml, 0.5ml/h, 1ml respectively. At 4, 8, 16 and 24h postoperatively, pain scores in VAS, comfort scale in BCS, sedation scores with Ramsay score, and the incidences of nausea, vomiting, pruritus, respiratory depression were assessed. Drug consumption in the first 24h and the D/D ratio (demand/deliver) were also recorded. Results VAS and BCS scores showed no significant difference among the 3 groups, but drug consumption within the first 24h and the D/D ratio in group T were higher than those in other 2 groups (P0.05). 8 patients in group T, 5 in group B and 4 in group M suffered from nausea; 1 patient in group T, 2 in group B and 3 in group M complained of pruritus. No respiratory depression was observed in all cases. Conclusion Tramadol and buprenorphine can be safely used as PCIA in patients undergoing upper abdominal surgery, but they are not superior to morphine.

AIM:To evaluate the efficiency of vitrectomy combined with inferior scleral buckling for a special kind of retinal detachment.
METHODS: Nineteen eyes of special retinal detachment had following features: 1 ) the course was more than 6mo;2) there were at least one hole located in the 5 : 00 - 7 : 00 of the marginal retina; 3 ) the detachment range of retina more than 270 degrees and retinal proliferation in retinal detachment. The 19 eyes who received vitrectomy combined with inferior scleral buckling, retinal anatomic reattachment and visual function recovery was observed.
RESULTS: Among these 19 eyes, all eyes retinal anatomic reattachment and best corrected visual acuity ( BCVA ) was improved in various degrees. The BCVA was 0. 01-0. 1 in 5 eyes, 0. 12-0. 3 in 9 eyes, and ≥0. 4 in 5 eyes.
CONCLUSION: It is an effective method to vitrectomy combined with inferior scleral buckling for the special kind of retinal detachment which has following features:1) the course was more than 6mo;2) there were at least one hole located in the 5:00-7:00 of the marginal retina;3 ) the detachment range of retina more than 270 degrees and retinal proliferation of cable in retinal detachment.

Objective To assess the value of thinprep liquid based cytology test (TCT) and Besthesda system (TBS) in diagnosis of cervial lesions. Methods 11000 cases of cervical lesions were detected with TCT and TBS.The samples of atypical squamous cells(ASC) and more severe than ASC lesions were classified into postive cytology,and then cytological results were compared with pathological examination results of cervical biopsies.Results The satisfactory rate of TCT samples was 96.36%, and the postive rate of abnormal epithelial cells diagnosed by TCT was 10.96%(1206/11000). Among 1206 cases, 15 cases(0.14%) of CA, 89 cases (0.81%) of HSIL, 449 cases (4.08%) of LSIL, 73 cases (0.66%) of ASC-H and 580 cases (5.27%) of ASC-US and AGUS. 1128 cases with postive cytologic results received pathological examination. The pathological positive rate of CA, HSIL, LSIL, ASC-H, and ASC-US and AGUS were 100%, 100%, 67.12%, 54.17% and 14.09%, respectively. The coincident rate of two examination methods was 100% for CA, 91.1% for HSIL,57.82% for LSIL and 27.78% for ASC-H. Conclusion TCT and TBS can accurately detect cervical cancer, precancerous lesions and infection of bacteria, virus and other pathogens, and at present is a means of screening cervical cancer.
