OBJECTIVE: To investigate superiorities of a special needle-over-cannula adopting different location methods for continuous femoral @entity616 (CFNB) for @entity1746 . METHODS: 60 elderly @entity1 intending to receive scheduled knee or hip replacement surgery were recruited and divided into 3 groups randomly. Group 1 (n=20) adopted fascial pop for continuous femoral @entity616 and @entity86 with indwelling cannula. Group 2 (n=20) adopted location guided by B ultrasound, and Group 3 (n=20) adopted fascial pop combined with B ultrasound. RESULTS: There was significant difference in the performing time of cannula indwelling on average between each two groups (P<0.01). There was no significant difference among three groups about visual analogue scale (VAS) score, Ramsay sedation score (RSS), incidence of @entity390 and vomit, or @entity1 's satisfaction at 6, 12, 24 and 48 h. Infection at the puncture site, toxic reaction of local anesthetics and @entity1576 were absent during the cannula indwelling. All the @entity1 did not receive any other analgesic, and the indwelling time of external cannula was 45.3 hours on average. There was only one @entity1 in group 2 who felt mild @entity158 in front of the thigh after removing the indwelling cannula. No stolidity or other abnormal symptom was found among the remaining @entity1 . CONCLUSIONS: Shorter indwelling cannula time and higher success rate of single attempt placement suggest that fascial pop combined ultrasound guidance is worth for clinical recommendation.
