1.Side effects of spinal anesthesia with Marcaine 0.5%
Journal of Vietnamese Medicine 1999;233(2):4-8
Spinal anesthesia with Marcaine 0.5%, for various kinds of operations was evaluated for complications. 90 patients were randomly allocated in to 2 groups: Group I: using isobaric Marcaine 0.5% and Group II: using hyperbaric Marcaine 0.5%, Patients were put on vigilant monitored for detecting effects on respiratory and cardiovascular system peri and postoperatively. Results: Group I and II showed significant different effects on cardiovascular system (P<0.05) by the deduction on blood pressure (>20%): group I: 2.22%; group II: 8.89% and the deduction on mean pulse: group I: 2.18 beat/minute; group II: 13.13 beat/minute. Affect on respiratory system was trivial in both groups. Other complications were not differ significantly (p<0.05) including: Nausea and vomit: group I: 2.22%; group II: 4.44%; Chill: group I: 2.22%; group II: 6.66%; Headache: group I: 4.44%; group II: 6.66%.

2.Spinal anesthesia with 0.5% isobaric Marcaine for lower extremity surgery
Journal of Medical and Pharmaceutical Information 2000;8():21-23
The study was carried out in the Department of Anesthesia, Military Hospital 103. 45 consent informed patients underwent spinal anesthesia with 0.5% Marcaine for lower extremity surgery. The level and the quality of sensory block and motor block were assessed. Results: Sensory block assessment using pinprick showed the onset of analgesic effect appeared at the T12 after 6.24 (t.SE±0.63) minutes; duration of analgesia after 20 min of induction was found up to T6 in 5 patients. Analgesia satisfied for the surgeries was evaluated as good in 91.11% and medium in 8.89% of the patients. Motor block was assessed using four-point Bromage scale. The onset of first degree motor paralysis was 4.96 (t.SE±0.63) min; duration prolonged for 145.67 (t.SE±8.53) min. Quality of paralysis was also assessed; first degree: 100%, second degree: 88.89%, third degree: 66.67% of patients. Hypotension (20% down from the original value) was found in 2.22% and headache in 4.44%. There was no any evidence of respiratory suppression.

3.Influence of patient position in spinal anesthesia with hyperbaric marcain 0.5%
Journal of Vietnamese Medicine 2005;311(6):40-45
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

4.Comparing the percentage of headache following spinal anesthesia with Whitacre needle and Quincke needle
Journal of Medical and Pharmaceutical Information 2005;0(12):22-25
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
