"Influence of a Whitacre Spinal Needle Orifice Direction on the Level of Sensory Blockade" by McShane, Burgus, Kapp, and Wieczorek (2000). The purpose of this study was to determine effects of the direction of the Whitacre spinal needle orifice with regard to level of sensory blockade and differences in time, during injection of anesthetic into the subarachnoid space. Subjects (n = 50) were a convenience sample of patients seeking elective surgery. The pinprick method was used to collect data, which was analyzed with descriptive, t-test, and chi-square statistics. Findings showed no significant differences for effects on level of sensory blockade or time periods.

The subjects for the study included a convenience sample of 50
