Abstract
The dimensions of currently available spinal needles (0.7 mm (22-gauge) to 0.45 mm (26-gauge) external diameter) were measured and compared with the International Standard (ISO 7864-1984 E). The in vitro performance of the needles was assessed by comparing times to appearance of cerebrospinal fluid and flow rates through the needles. There were wide variations in the measurements and performance of the different needles.This publication has 0 references indexed in Scilit:
