ABSTRACT
Objective Analyze current clinical practice guidelines related to pre-anesthesia as-sessment to provide a resource for healthcare providers (or institutions)seeking protocols of their own.Methods National and international guideline databases were searched along with healthcare or-ganizations and associations.Content analysis method was used to analyze clinical practice guidelines searched from internet and obtained in the database search.Results Five clinical practice guidelines were included.A total of 39 items related to pre-anesthesia assessment were identified and when divid-ed into 3 essential areas:1)past history and present medical,2)physical examination,and 3)labora-tory examination.There is no guidance to general anesthesia currently in China.Pre-anesthesia testing in the presence of specific clinical characteristics was recommended.Conclusion We should develop local clinical practice guidelines of preanesthesia assessment with consideration of the actual medical situations in China.
ABSTRACT
<p><b>OBJECTIVE</b>To study pharmacokinetic of puerarin in rats following different methods of administration of Tongqiao Sanyu prescription.</p><p><b>METHOD</b>Tongqiao Sanyu prescription was administered to rats by caudal vein injection, nasal administration and oral administration. Plasma samples were extracted with methanol and the plasma concentration of puerarin was analyzed by RP-HPLC. The pharmacokinetic parameters and bioavailability were calculated with Kinetica software.</p><p><b>RESULT</b>The main pharmacokinetic parameters were as follows: AUC(0-infinity) of caudal vein injection was (787.99 +/- 70.44) mg x min x L(-1); AUC(0-infinity) of nasal administration was (376.56 +/- 93.93) mg x min x L(-1); AUC(0-infinity) and oral administration (The dose was decuple higher than that of caudal vein injection and nasal administration) was (491.18 +/- 110.64) mg x min x L(-1). The absolute bioavailability of puerarin was 47.78% by nasal administration and 6.23% by oral administration.</p><p><b>CONCLUSION</b>The bioavailability of nasal administration is higher than oral administration significantly, this result can provide some scientific foundantion for the method of administration and the reform of dosage form of Tongqiao Sanyu prescription.</p>
