60 subjects aged 21-42 with an indication of caesarean section underwent spinal aneasthesia by 10mg Marcaine 0.5%. Patients were met ASAII criterion. Among them 8.2% had got mild blood hypertention. Subarachnoid anaesthesia gave high efficacy because its prompty effect and prolonged anaesthesia, the patients were vigilant without complication owing to aspiration of gastric succus. Subarachnoid anaesthesia did not suppress the respiration and the central nervous system. The post operative monitoring was more simply, possibly to prevent anaesthesic complications for the mother and especially for the infant.

Effect of marcaine plus fentanyl combination for lumbar epidural anesthesia was investigated in random series of 33 patients who were undergoing lumbar discectomy. Patients received 1mg/kg marcaine with 1mcg/kg fentanyl. The volume of local anesthetic solution was calculated basing on the number of segments that needed to block: 1.5 - 1.6ml per segment. It was found that the marcaine plus fentanyl combination provided high effect (100%) on epidural anesthesia, rapid onset (7.51.8 min), long working duration (33070 min), caused milder hemodynamic changes, decreased the incidence of adverse events and produced satisfactory operating condition.

A prospective study involved 64 patients (43 men, 21 women) aged from 20 to 62 years with lumbar disc herniation who had operated at Military Hospital 103. These patients were divided into 2 groups. Group 1 received marcaine (0.25%-0.375%) plus fentanyl, group 2 received marcaine (0.35% - 0.5%) alone for lumbar epidural anesthesia. The volume of local anesthetic solutions injected epidurally was calculated based on number of segments that had to block, with dose of 1.5 - 1.6 ml per segment. The results showed that compare with marcaine alone, the combination of marcaine and fentanyl provided better analgesic effect, faster onset and longer duration of action, caused milder hemodynamic changes, decreased the incidence of adverse effects and produced satisfactory post-operative condition

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.

BACKGROUND: The purpose of our study was to evaluate whether, by varing the duration of lateral decubitus, subarachnoid administration of hyperbaric bupivacaine in a lateral decubitus position could produce a differential spread between the dependent and nondependent sides, and also to determine the clinical advantage of this procedure. METHODS: In a lateral position with the operating side dependent, all patients received 15mg of hyperbaric 0.5% bupivacaine and were randomized into four groups according to the duration of lateral decubitus after subarachnoid injection: Group I: patients immediately turned supine after the injection, Group II: 5 min in lateral decubitus position after the injection, then supine, Group III: 10 min in lateral decubitus position after the injection, then supine, Group IV: 15 min in lateral decubitus position after the injection, then supine. The maximum sensory block level using pinprick test, the time to maximum sensory block, the duration of sensory block, the time to complete motor block and the duration of complete motor block in the dependent and nondependent sides were measured. RESULTS: There were no statistical difference in maximum sensory block level, duration of sensery block, and duration of complete motor block between both sides in the same group nor among four groups. CONCLUSIONS: In conclusion, there was no significant influence of lateral decubitus on the spread of hyperbaric bupivacaine and the present study does not demonstrate any clinical advantage of a prolonged lateral position for 15 min after subarachnoid injection.

The changes of methemoglobin concentration in the blood after the use of lidocatine or Marcaine were investigated in the human and the rabbits. In the human the drugs were give by the epidural route and intramuscularly in rabbits. Lidocaine did not increase the methemoglobin concentration in humans but marcaine increased the methemoglobin concentration in the blood.

BACKGORUND: The relationship among age, height and sensory block height in elderly patients who underwent spinal anesthesia using 0.5% heavy bupivacaine were studied. METHODS: Ninety-seven elderly patients, 65 years of age or older, who were scheduled for spinal anesthesia were divided into four groups. 8 mg of 0.5% heavy bupivacaine was injected in patients who were shorter than 160 cm, and 9 mg was injected in patients who were taller than 160 cm. Then they were further divided into a 65 74 year old group and an older than 75 year old group, and the area of sensory block was compared by the age and height. RESULTS: Sensory block height was not significantly different between the 65 74 year old group and the older than 75 year old group. Height did not correlate with sensory block height in all groups, and the distribution shapes showed variable patterns. CONCLUSiONS: The effect of age and height on the spinal sensory block height in elderly patients is small.
