BACKGROUND: 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 some of these factors on sensory blockade level by using L2-3 interspace. METHODS: Eightyfive patients, ASA physical status I - Il, 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 flexed and non-full flexed lateral position on sensory blockade level was studied whereas other factors such as puncture technique, dosage and concentration of drug and patients position after injection, were kept constant under the same condition. And also studied the effect of degree of flexion at injection on the sensory blockade level. RESULTS: Height and CSF pressure were correlated with sensory blockade level at 10 minutes after injection(R2=0.14, P<0.01). Only height was correlated with sensory blockade level at 30 minutes after injection(R2=0.09, P<0.0l). CONCLUSIONS: Only height was correlated with sensory blokade level at 30 minutes. So, height might be considered as the most impressive minor factor affecting the extent of sensory blockade level.

A randomized study was carried out on 90 patients from 16 to 65 age old were surgically operated lower extremities at Anesthesia Department of Viettiep Hospital from February 2004 to February 2005. The patients were divided into 2 groups: ASA I and ASA II. Results: after 30 initial minute of anesthesia, the pulse frequency decreased in 40/45 patients of group I (88.89%), in 44/45 (97.78%) patients of group II. There wasn’t any case in two groups had the pulse less than 60 times/minute. There were 42/45 patients (93.33%) in group I and 45/45 patients (100%) in group II had a decrease of artery pressure during 30 minute of anesthesia. Respiratory frequency pre and post anesthesia in two group were different not significantly (p>0.05). There was no case of respiratory failure required interventions. Pre- post anesthesia, SpO2 in group I and group II changed not significantly (p>0.05). The side effects during surgery: nausea, vomit, tremble and shiver; after surgery: headache, urine retention. The position of patients was used in order to distribute much more on onside had excellent effect for lower extremities surgery. Levels of sensory and motor block were very good without significant side effect

A prospective study was conducted on 380 patients at age of 16 to 65 who were operated at The Anaesthetic and Recuperative Department of Vietnam-Sec Hospital from Jun 2003 to April 2005. The patients were divided randomly into two groups: Group I using the needle anesthesia Whitacre 25G and Group II using the needle anesthesia Quincke 25G. Results: the pulses of both groups before and after anesthesia were different (p>0.05), the arterial pressure 30 minutes after anesthesia of both groups reduced (p>0.05) the rate of respiratory before and after anesthesia of both groups were different, no case with side effect on respiratory which needed intervention. Spinal anesthesia with hyperbaric Marcain 0.5% (dose 0.2mg/kg) at L3-L4 interspaces causes completely anesthesia for lower extremities operations, side effects were negligible
