Objective To evaluate the effects of different rates of remifentanil infusion on cardiovascular response to tracheal intubation in older patients. Methods Thirty ASA Ⅰ-Ⅲ patients aged 65-75 yrs weighing 50-80 kg scheduled for elective abdominal operation were randomly divided into 3 groups (n = 10 each) according to the remifentanil infusion rate: group A 0.05 ?g?kg-1?min-1; group B 0.1 ?g?kg-1?min-1 and group C 0.15 ?g ?kg-1?min-1. The patients were premedicated with intramuscular phenobarbital 0.1 g and atropine 0.5 mg. Radial artery and subclavian vein were cannulated for BP and CVP monitoring and blood sampling. ECG, BP, HR and SpO2 were monitored during anesthesia. After 10 min stabilization induction of anesthesia was commenced with remifentanil infusion for 10 min. Midazolam 0.1 mg?kg-1 was then given Ⅳ. Succinylcholine 1.5 mg?kg-1 was given to facilitate intubation after the patients lost consciousness. BP and HR were recorded immediately before induction of anesthesia (T0, baseline), immediately after intubation (T1 ) and at 2, 5 and 10 min after intubation (T2 ,T3 ,T4 ) . Cardiovascular intubation response was defined as increase in SP or HR by 15% of the baseline value within 2 min after intubation. Blood samples were taken at T0-4 for determination of plasma concentration of norepinephrine (NE) and epinephrine (E) by HPLC. Side effects such as chest wall rigidity and hypotension were also recorded. Results The cardiovascular intubation response rate was significantly higher in group A (80%) than in group B (10% ) and C (10% ) . The incidence of side effects was significantly higher in group C (70% ) than in group B (20%) and A. Plasma NE and E concentrations were significantly increased after intubation in group A (at T2-4) and B (at T2,3) as compared with baseline values at T0; while in group C only plasma NE concentration was significantly increased at T2 and T3 and there was no significant change in plasma E concentration after intubation. The plasma NE and E concentrations were significantly higher in group A (T2-4) and B (T2,3) than in group C. Conclusion The appropriate infusion rate of remifentanil for tracheal intubation is 0.10 ?g?kg-1 ?min-1 in older patients.

Abstract?AIM: To determine the relation between each of the optical coherence tomography ( OCT) patterns, etiologies and visual acuity in patients with cystoid macular edema ( CME) .?METHODS:Fifty-seven eyes with CME from 52 patients were included in our study. The data of this cross sectional study was collected rfom p atient s wtih CME assessed by OCT, who also underwent fun dus photography and visual acuity test the same day. The best corrected visual acuity ( BCVA ) was assessed by using E chart a nd converted in logarithm of the minimum angle of resolution( logMAR ) . Thevisual acuity varied from 2.3 logMAR to 0 logMAR w ith a mean of 1.11±0.57. The etiology was determined from medical history and the fundus ph otograph of the patient. Four O CT grades established according to ratio between the vertical size of largest cyst and the maximum macular thickness (<30 %,≥30% <60%,≥60% <90%and≥90%) were considered. The correlation was established by calculating the Pearson's correlatio n coefficient “r” and the statistical significance was considered when P value was inferior to 0.05.?RESULTS: OCT grade I V was the most associated with very severe visual loss with the greatest mean VA of 1.96± 0.23 logMAR and the correlation between OCT grades and visual acuity was strongly statistically significant ( r =0.729, P <0.001 ). The central retinal vein occlusion ( CRVO) was the most underlying disease associated with worsev ision, with the gre atest mean VA of 2 logMAR and the correlation was statistically significant ( r=0.375, P=0.004).Another associated OCT pattern, the disruption of bot h inner segment/outer segment ( IS/OS) and external limiting membrane ( ELM) , was inversely associated with severe visual loss ( high mean VA=1.11 ±0.57 logMAR, with statistically significant correlation, r=-0.346, P=0.008 ) . The presence of both vitreoretinal traction components and outer retinal layers disruption were significantly associated with OCT grade IV ( r=0.390, P=0.003) and CRVO (r=0.362, P=0.006).?CONCLUSION:In this study, the OCT fourth grade and CRVO seem to be more significantly associated with the worse vision in patients with CME.

OBJECTIVE To find out the main polluting bacteria in the medical establishments in Langfang city so as to direct the work of disinfecting and reduce the rate of the nosocomical infection in the medical establishments. METHODS The environment of the medical establishments was divided to five groups, including the air, the object surface , the medical workers hands, the using disinfectant and the medical equipment. RESULTS The main polluting bacteria in the air, on the object surface and the medical equipment were the Gram-positive cocci. The main polluting bacteria in the using disinfectant was the Gram-negative bacilli. The Gram-negative bacilli were more than the Gram-positive cocci on the hands of the medical worker. The main bacteria were Staphylococcus epidermidis, Escherichia coli and Acinetobacter. The using disinfectant was with the maximum qualified rate (98.8%), and with only 6 samples unqualified. The air was with the minimum qualified rate (58.22%). CONCLUSIONS No spores gemma which are difficult to be killed have been found and the unqualified samples in various environment are mainly due to the weak awareness of disinfection and the careless attitude.
