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

In a randomized study of 16 pediatric patients undergone open-heart surgery, the postoperative recovery time and ventilatory support time of the patients anesthetized with fentany (fentanyl group, n=8) was compared with those of the patients anesthetized with morphine (morphine group, n=8). All patients were premedicated with 0.1 mg/kg of morphine and 0.008mg/kg of glycoppyrolate i.m. 1hr prior to anesthesia. In morphine group, anesthesia was induced with morphine 0.5mg/kg and thiopental 3 mg/kg and in fentanyl group with fentanyl 5 ug/kg and thiopental 3 mg/kg. Anesthesia was maintained with assigned opiate based upon cardiovascular signs. The total doses of opiates are 3.2mg/kg in morphine group and 34.3pg/kg in fentanyl group. In fentanyl group the time to regain consciousness (107+/-53min), ventilatory support time (209+/-53min) and the time from end of operation to extubation (589+/-82min) are significantly shorter than in morphine group (142+/-41min, 838+/-220min, 1470+/-269min, respectively). From the above results fentanyl is more suitable i.v. anesthetic agent for open-heart surgry in respect of postoperative ventilatory care.

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: Intrathecal opioid, a useful adjunct to prolong analgesic effects, potentiates spinal anesthesia. The present study was designed to evaluate the effect of intrathecal fentanyl on the hypnotic requirements of propofol during spinal anesthesia. METHODS: Sixty patients scheduled for elective urologic surgery under spinal anesthesia were randomly assigned to one of four groups. In Group 1 (n =15), spinal anesthesia was performed with hyperbaric bupivacaine 10 mg, in Group 2 (n = 15) with hyperbaric bupivacaine 10 mg plus fentanyl 10microgram, in Group 3 (n = 15) with hyperbaric bupivacaine 10 mg plus fentanyl 20microgram, and in Group 4 (n = 15) with hyperbaric bupivacaine 10 mg plus fentanyl 30microgram. After performing spinal anesthesia, the target plasma concentration of propofol was set at 2.0microgram/ml. Effect site concentration (Ce) was measured when the BIS's reached 80 or 70. Ce was titrated to maintain a BIS of 70-80. Observer's sedation scoring (OAA/S), systolic and diastolic pressures, SpO2 and total infusion dose were measured every 10 minutes for 1 hour. RESULTS: Ce's at a BIS of 80 were 1.2+/-0.3microgram/ml (Group 1), 1.0+/-0.3microgram/ml (Group 2), 0.9+/-0.2microgram/ml (Group 3), and 0.8+/-0.2microgram/ml (Group 4), respectively. Ce's at a BIS of 70 were 1.6+/-0.2microgram/ml (Group 1), 1.5+/-0.4microgram/ml (Group 2), 1.2+/-0.3microgram/ml (Group 3), and 1.2+/-0.3microgram/ml (Group 4), respectively. Ce's of Group 3 and Group 4 at BISs of 70 and 80 were significantly lower than those of Group 1 (P<0.05), and the propofol requirements of Groups 3 and 4 to maintain a BIS of 70-80 were significantly less than those of Group 1 (P<0.05). CONCLUSIONS: These results indicate that adding more than 20microgram of fentanyl to hyperbaric bupivacaine for spinal anesthesia reduces the hypnotic requirement of propofol.

Stress cardiomyopathy is characterized by transient systolic dysfunction of the apical and/or mid segment of the left ventricle. The main pathophysiology of stress cardiomyopathy is the excessive release of catecholamine. Opioid withdrawal can initiate a surge of catecholamine and an attack of stress cardiomyopathy. In this case, we report a case of stress cardiomyopathy due to iatrogenic withdrawal from transdermal fentanyl.
