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

Diprivan is intravenous anesthetic agent with many advantages. 20 patients received the diprivan for abdominal fatty removal. The results have shown that the homodynamic during operation was stable. The hypotension occurred only during preanasthesics. The heart beat was also reduced due to the change of sensitivity of sensory focus and pressure reflex, this reduction was corresponded with hypotension but within allowed range. These easily controlled and were stable throughout an operation

BACKGROUND: We designed this study to find the appropriate dose of fentanyl for the prevention of emergence agitation in pediatric tonsillectomy patients under sevoflurane anesthesia. METHODS: Sixty pediatric patients receiving sevoflurane anesthesia for tonsillectomy was assigned to 3 groups. Fentanyl 0.5microgram/kg (group 1), 1.0microgram /kg (group 2), or 1.5microgram/kg (group 3) was administered intravenously 10 min before the end of surgery. Agitation score was checked at the postanesthesia care unit. RESULTS: The results showed a lower incidence of severe agitation in groups 2 and 3 than in group 1. There was no difference between groups 2 and 3. CONCLUSIONS: For preventing emergence agitation after sevoflurane anesthesia, we recommend using fentanyl in a dose of more than 1.0micrgram/kg.

The effects of fentanyl anesthesia on the changes of hemodynamic(HR, BP), blood suger, electrolytes and ABGA during induction of anesthesia and cardiopumonary bypass under fentanyl anesthesia were studied in three groups of 30 patients. The results were as follows: 1) The changes of HR & BP were significatly decreased under fentanyl anesthesia compaired to morphine anesthesia. 2) The level of blood sugar was increased during whole procedures in all groups and it was the least in large dose fentanyl group. 3) The changes of electrolyte and arterial blood gas value during CPB were not remakable.

BACKGROUND: This study compared the efficacy of intravenous fentanyl with lidocaine as a pretreatment for the prevention of a withdrawal response after a rocuronium injection. METHODS: Eighty patients were divided into four groups according to the drugs used for pretreatment as follows: group I: normal saline, group II: lidocaine 0.5 mg/kg, group III: lidocaine 1.0 mg/kg, group IV: fentanyl 1microgram/kg. Twenty seconds after inducing anesthesia, each pretreatment drug was injected. After twenty seconds, rocuronium was injected. The incidence and severity of the withdrawal responses was assessed. The BIS value and heart rate was recorded at each point (T0: baseline, T1: pretreatment drug injection, T2: 10 seconds after pretreatment drug injection, T3: rocuronium injection, T4: 10 seconds after rocuronium injection, T5: 20 seconds after rocuronium injection). RESULTS: The incidence of withdrawal movement was significantly lower in groups II and III than in groups I and IV (P = 0.002). The BIS was significantly lower in group IV than in groups I, II and III at T2 and group I at T3 (P < 0.05). The heart rate at T4 was significantly lower in group IV than in group II (P < 0.05). An assessment of BIS at the withdrawal movements showed a significantly higher value in the severe group than in the none and mild groups at T5 (P < 0.05). CONCLUSIONS: A pretreatment with 0.5 mg/kg or 1.0 mg/kg of lidocaine effectively reduced the incidence of a withdrawal response by the rocuronium injection. However, 1.0 mg/kg of lidocaine most effectively prevented the withdrawal response without causing any significant changes in heart rate.

BACKGROUND: This study examined the efficacy of patient-controlled epidural analgesia (PCEA) for post-cesarean section pain control and compared the suitability of four different volumes of continuous background infusion (CBI). METHODS: Sixty patients were received 0.125% bupivacaine with 5 g/ml fentanyl by PCEA (2 ml of demand dose and 10 minutes of lockout interval) and CBI. Experimental groups were divided four groups according to the volumes of CBI; 1 ml/hr, 2 ml.hr, 3 ml/hr and 4 ml/hr of CBI during 48 hours postoperatively. RESULTS: Total amount of fentanyl and bupivacaine consumption was significantly higher in 1ml/hr of CBI group than 2 ml/hr of CBI group during first 24 hours, and in 4 ml/hr of CBI group than 1 ml/hr and 3 ml/hr of CBI group during second 24 hours. CBI/maximum hourly demand dose was 15~23%. There is no significant difference between the groups in pain score, side effects and patient's satisfaction. CONCLUSIONS: This study suggests that two or three ml/hr of CBI can provide the most effective postoperative analgesia and the optimal ratio of CBI/maximum hourly demand dose is about 20%.
