Objective To investigate the effect of esmolol pretreatment on propofol injection pain..Methods Ninety patients undergoing breast cancer surgery under general anesthesia were ran-domly assigned into three groups (n=30 each).Group E were pretreated with 5 mg/ml(total 2 ml)es-molol group L with 20 mg/ml (total 2 ml)lidocaine and group N with 2 ml normal saline.After one minute,each group was administrated propofol intravenouly.The pain and hemodynamic data were re-corded.Results Compared with group N,propofol injection pain degree decreased obviously in groups E and L (P <0.05).propofol injection pain occurred in 25 (83.3%)in group N,was signifi-cantly higher than that of 12 (40.0%)in group E and 14 (46.7%)in group L (P <0.05),propofol injection pain had no significant difference between groups E and L.Compared with T1 ,SBP,DBP decreased in groups E and L at T2 ,SBP decreased in group N at T2 significantly (P <0.05).Com-pared with T2 ,DBP was significantly higher at T3 in group E (P <0.05).Conclusion Pretreatment with low dose esmolol was effective in attenuating pain during propofol injection.

Objective To compare the influences of different routes of nutrition on the outcome and respiratory muscle strength of elderly patients in respiratory intensive care unit (RICU). Methods Totally 147 elderly patients in RICU were equally randomized into combined nutrition group ( combinination of parenteral nutrition and enteral nutrition), total enteral nutrition (EN) group, and total parenteral nutrition (PN) group. The changes of energy metabolism, respiratory muscle strength, and short-term outcome were observed or determined.Results Plasma albumin (ALB), hemoglobin (Hb), creatinine (Cr) levels, and nitrogen balance significantly increased in all group 7 days later ( all P ＜ 0. 01 ), while blood urea nitrogen (BUN) significantly decreased ( P ＜0.01 ). The increase of ALB, Hb, Cr levels, and nitrogen balance were significantly more remarkable than that in EN group and PN group (P＜0.05 or P＜0.01). The decrease of BUN level in the combined nutrition group was significantly more remarkable than that in EN group ( P ＜ 0. 05 ). After nutritional support, the maximum inspiratory pressure in the combined nutrition group (P =0. 021 ) and EN group (P = 0. 011 ) became significantly higher, and occlusion pressure at 0.1 second inspiration level in the combined nutrition group became significantly lower ( P =0. 025). The incidences of infectious and non-infectious complications in PN group were significantly higher than those in EN group (P = 0. 002 and 0. 017, respectively) and combined nutrition group ( P = 0. 005 and 0. 004, respectively). Gastric retention was more common in EN group than that in PN group ( P = 0. 035). The weaning time,length of RICU stay, length of hospital stay and 20-day-mortality were significantly decreased in the combined nutrition group than those in the other two groups ( all P ＜ 0. 05 ). Conclusion The effectiveness of the combined application of PN and EN is superior to PN or EN alone in improving nutritional status and respiratory muscle strength as well as in improving the short-term outcome in elderly patients in RICU..

Objective The aim of this study is to evaluate the effects of drug,electric cardiovertion,radiofrepuency ablation and implantable anti-atrial-fibrillation pacemaker on patients with persistent idiopathic atrial fibrillation.Methods 58 patients with persistent idiopathic atrial fibrillation were treated with drug or electric cardjovertion,radiofrequence ablation and anti-atrial-fibrillation pacemaker.Results There were 30 patients successfully converted to sinus rhythm by drug.The mean conversion time of drug was 8?5 days.22 patients were converted by electric cardioversion.10% of cases(6 of 58)failed to convert by both methods.In follow-up period,12 cases of patients were healed,19 cases got significant improvement,14 cases got moderate improvement,8 cases had no improvement.The total efficiency rate was 76%.18 cases in successful cardioversion patients were healed,5 cases got significant improvement,5 cases got moderate improvement,4 cases had no improvement.The total efficiency rate was 75%(14 of 18).2 cases got improvement by anti-atrial-fibrillation pacemaker.Conclusion Combined treatment of drug,electric cardioversion,radiofreqency ablation and anti-atrial-fibrillation pacemaker can imrove cure rate of persistent idiopathic atrial fibrillation.

Objective:To investigate the onset mechanism of cervical vertigo from the proprioceptive sensation and provide clinical basis for its treatment.Methods:Among the 121 cases that conformed to the diagnostic criteria of cervical vertigo,70 cases who presented with negative neck-rotation test and cervical vertigo without obvious vascular factors by transcranial Doppler(TCD)were assigned to the observation group,while 51 cases who presented with positive neck-rotation test and cervical vertigo due to spasm of vertebral basal artery or insufficient blood supply by TCD were assigned to the control group.The cases in the two groups were treated once every day,5 days make up one treatment course and the resuIts were statistically analyrzed after one treatment course.Results:The skull triaxial spatial offset of the cases in the two groups were significantly reduced after the treatment (P<＜0.01).However, there was no statistically significant difference between the skull triaxial spatial offset between the two groups (p＞0.05).It is not conclusive that the therapeutic effect in the two groups was significantly different after one treatment course.Conclusion:Tuina manipulation therapy can improve the skull spatial ofrset repositioning ability of the Patients.

Objective To determine the optimum dose of oxycodone inhibiting responses to tracheal intubation with a double-lumen endobronchial tube in patients undergoing one-lung ventilation (OLV).Methods Sixty adult patients aged 55-64 yr, weighing 60-80 kg, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective thoracic surgery requiring OLV, were randomly divided into 3 different doses of oxycodone groups (O1-3 groups, n =20 each).Anesthesia was induced with iv midazolam 0.05 mg/kg, oxycodone 0.30, 0.35 and 0.40 mg/kg (O1.3 groups, respectively) , propofol 1.5 mg/kg and rocuronium 0.9 mg/kg.The patients were tracheally intubated using a double-lumen endobronchial tube and mechanically ventilated.Before anesthesia induction (T0) , immediately before and after intubation (T1,2) , and 1 and 5 min after intubation (T3.4) , arterial blood samples were taken to determine the concentrations of serum norepinephrine (NE) and epinephrine (E) using high-performance liquid chromatography.The occurrence of bucking, body movement, hypertension, and tachycardia were observed.Results The concentrations of serum NE and E were significantly increased at T2,3 than at T1 in group O1 (P＜0.05).Compared with group O1 , the concentrations of serum NE and E were significantly decreased at T2,3 , and the incidence of bucking, body movement, hypertension, and tachycardia was decreased in O2 and O3 groups (P＜0.05).There was no significant difference in the parameters mentioned above between O2 and O3 groups (P ＞ 0.05).Conclusion The optimum dose of oxycodone inhibiting responses to tracheal intubation with a double-lumen endobronchial tube is 0.35 mg/kg in patients undergoing OLV.

OBJECTIVETo investigate the type and corresponding operation methods of ulnar lateral mass in distal radial fractures.
