Ultrasound-assisted vs. landmark-guided paramedian spinal anaesthesia in the elderly: A randomised controlled trial
BACKGROUND
Neuraxial ultrasound might improve the efficacy of spinal anaesthesia but this has not been tested for the paramedian approach in the elderly.
OBJECTIVE
The current study aims to assess whether the ultrasound-assisted paramedian technique can decrease the number of needle passes required for success compared with the landmark-guided paramedian technique in the elderly.
DESIGN
Randomised controlled study.
SETTING
Single-institution, tertiary-level hospital in Seoul, Republic of Korea from October 2017 to January 2018.
PATIENTS
Eighty patients aged at least 60 years undergoing orthopaedic surgery.
INTERVENTION
All received paramedian spinal anaesthesia by either the landmark-guided or preprocedural ultrasound-assisted technique.
MAIN OUTCOME MEASURES
The number of needle passes required for successful dural puncture.
RESULTS
The number of needle passes (median [interquartile range]) was significantly lower (1.0 [1.0 to 2.0] vs. 4.5 [2.0 to 7.0]) and the success rate at first pass significantly higher at 65.0 vs. 17.5% in the ultrasound compared with the landmark group (both P
