    Abstract:
    Cost containment is a critical factor in today's healthcare industry, so finding ways to decrease length of stay is essential in anesthesia practice. We rely on rapid induction, recovery, and discharge to control cost in outpatient surgery. Subarachnoid block (SAB) is an acceptable anesthetic choice for many outpatient procedures. It is often underused because it may result in delayed discharge. The purpose of this study was to determine if orientation of the spinal needle during administration of SAB affects the time required to meet discharge criteria in a same-day surgical unit. Patients undergoing surgical procedures deemed appropriate for short-acting lidocaine spinal anesthetic were recruited for this randomized, posttest, prospective study. All patients received a hyperbaric lidocaine spinal administered using a 25-gauge Whitacre needle. The needle was oriented in a cephalad (group A) or a lateral (group B) direction. Time to discharge was determined by calculating time elapsed between administration of the SAB and the time when the patient met discharge criteria. The statistical analysis included 50 patients (group A, n = 30; group B, n = 20). Demographics (except weight) were not statistically different between the groups. Total hospital time did not differ between the groups. Regardless of needle orientation, patients in both study groups achieved discharge criteria in similar amounts of time.
