The puncture interspace in observation group was located at the L 1-L 2 and control group at L 3~L 4. The analgesia method and drug concentration of the two groups were identical.
Analgesia method 1 (5 mg butorphanol and 2 mg droperidol were diluted to 60 mL with saline) was used in group C1 and P1, while group C2 and P2 used method 2 (only 5 mg butorphanol changed into 6 mg), and group P3 used method 3 (adding 200 mg tramadol to method two).
Conclusion:Midazolam combined with ropivacaine on patient controlled epidural analgesia produces satisfactory postoperative analgesia with less complications,and is a better analgesia method.
Conclusion: Continuous epidural analgesia could improve pulmonary function after operation and promote oxygenation in lung, so it is a good postoperative analgesia method.
Conclusion The analgesic effect of 0.1% levobupivacaine combined with 0.3% tramadol for PCEA is definite. During analgesia,the functions of patient's circulation and respiration are all stable. This analgesic method is safe and effective for postoperative pain in the elderly.
CONCLUSIONS PCEA is a good analgesic method after thoracic surgery of(esophagus) carcinoma. It can promote patients to cough and reduce PTPI,therefore PCEA is a good method for preventing PTPI.
This study investigates analgesic and Physiological effects of ketaminc on thirty epidural anesthesia patients infused a single dose of ketamine 0.5mg/kg into their epidural space. The principal findings were the following. (1) The time of anelgesic was prolonged notably in the experiment group. ( 2 ) Most patients were perfectly conscious but a few with light somnolence. ( 3 ) There was no association with the respiratory system and circulatory system.(4 ) Retention of urine didn't occur and nousea and vom...
Pain is one of the most commom clinical symptom. There is still no satisfactory treatment for certain forms of pain. 71 cases with trigeminal neurolgia and 73 cases with migraine were treated with waveguide CO_2 laser. Significant relief of pain was observed. It is suggested that the mechanism for pain relief induced by this treatment was the body produced by opi- num--like pain suppresant or the Changes of metabolite of the local tissue which had been irradiated. So it is postulated that waveguide CO_2 las...
In order to study the pusr—operative analgesia effect of epidural injection with hypertonic saline,we observed 60 patients using double—blind method. The control group,the rate of effective post—operative analgesia is 3. 33%,all patients were injected with narcotics. The epidural hypertonic saline group,the rate of effective analgesia is 86. 67%,only 4 patients need narcotics. There are significient difference (P<0. 05, P<0. 01). The algesia effect of epidural hypertonic saline is equal to that of epidural ...
