Background:
@EN Many factors affecting the spread of spinal anesthesia have been investigated. But L3-4 or L4-5 interspace was choosen which was known as the site of buffering, in their study. We investigated the effect of someof these factors on sensory
blockade
level by using L2-3 interspace.
@ES Methods:
@EN Eightyfive patients, ASA physical status I-II, were involved in our study. Sensory blockade level was checked with pinprick test at 10 minutes and 30 minutes. The effect of age, sex height, weight, CSF pressure and pressure difference
generated
when
full fiexed and non-full flexed lateral position on sensory blockade level was studied whereas other factors such as puncture technique, dosage and condition. And also studied the effect of degree of flexion at injection on the sensory blockade
level.
@ES Results:
@EN Height and CSF pressure were correlated with sensory blockade level at 10 minutes after injection (R*=14, P<0.01). Only height was correlated with sensory blockade level at 30 minutes after injection (R*=0.09, P<0.01).
@ES Conclusion:
@EN Only height was correlated with sensory blokade level at 30 minutes. So height might be considered as the impressive minor factor affecting the extent of sensory blockade level. (Korean J Anesthesiol 1996; 30:321~326)
