The effect of lumbar epidural analgesia on the development of deep vein thrombosis of the legs after open prostatectomy 总被引:3,自引:0,他引:3
The occurrence of deep vein thrombosis (DVT) was studied by the 125-I-fibrinogen uptake test in 38 patients subjected to retropubic prostatectomy. The patients were randomly allocated to two groups: continuous lumbar epidural analgesia for up to 24 hours and general anaesthesia with intermittent positive pressure ventilation. Two of the 17 patients in the epidural group (12%) developed DVT in contrast 11 of the 21 patients in the general anaesthetic group (51%). The difference between the groups was significant. It is concluded that epidural analgesia offers a protection against postoperative DVT and is worth further investigation. 相似文献

Prevention of deep vein thrombosis after total hip replacement. The effect of low-molecular-weight heparin with spinal and general anaesthesia. 总被引:1,自引:0,他引:1
A Planès N Vochelle M Fagola J Feret M Bellaud 《The Journal of bone and joint surgery. British volume》1991,73(3):418-422
Enoxaparin, a low-molecular-weight heparin, has been used together with spinal or general anaesthesia in a prospective, randomised study of 188 consecutive elective hip replacements. Bilateral venography was performed on all patients on day 13 after operation. Group I (65 patients) received spinal anaesthesia and no immediate injection of enoxaparin. Group II (61 patients) received spinal anaesthesia and 20 mg of enoxaparin one hour after the onset of anaesthesia. Group III (62 patients) was operated on under general anaesthesia and received 40 mg of enoxaparin 12 hours prior to surgery. This group acted as the control group. In all three groups, 40 mg of enoxaparin was given 12 hours after the end of surgery and continued on a once-daily basis. Proximal DVT occurred in 6% of group I, 6.7% of group II and 6.5% of group III, not a significant difference. Distal DVT was present in 11% of group I, 5% of group II and 0% of group III; this was a highly significant difference (p = 0.007). Tolerance was good and the incidence of bleeding low in the three groups. Our results confirm the low rate of DVT in patients operated on under general anaesthesia with the standard procedure of 40 mg of enoxaparin on a once-daily basis started pre-operatively. The 40 mg-dose is also safe and effective in association with spinal anaesthesia if half the dose (20 mg) is injected an hour after the lumbar puncture. 相似文献

A Controlled Study on the Effect of Epidural Analgesia with Local Anaesthetics and Morphine on Morbidity after Abdominal Surgery 总被引:6,自引:0,他引:6

A hundred patients scheduled for elective abdominal surgery were randomized to either general anaesthesia (low-dose fentanyl) and systemic morphine for postoperative pain or combined general anaesthesia and epidural analgesia with etidocaine 1.5% intraoperatively (T4-S5) and bupivacaine 0.5% 5 ml/4 h for 24 h and morphine 4 mg/12 h for 72 h. Postoperative pain was better controlled by the epidural regimen (P less than 0.0001). We found no significant reduction in postoperative mortality (6% to 2%), pneumonia (28% to 20%), cardiac dysrhythmia (10% to 5%) and wound complications (14% to 11%) by the epidural analgesic regimen. The incidence of deep venous thrombosis (125I-fibrinogen scan) was 32% after general anaesthesia and low-dose heparin and 34% after epidural analgesia with no prophylactic antithrombotic treatment (P greater than 0.9). Postoperative weight loss and decrease in serum-albumin and serum-transferrin, as well as the reduction in haemoglobin and the need for postoperative transfusions, were similar in the two groups. Convalescence, as assessed by postoperative fatigue, restoration of bowel function (flatus, bowel movement and food intake) and the time until the patients were self-aided at their preoperative level, was not reduced by epidural analgesia. Since 50% of the patients in each group suffered from one or more of the above-mentioned postoperative complications, this epidural regimen was not effective in reducing postoperative morbidity after major abdominal surgery despite the achievement of adequate pain relief. 相似文献

In 50 patients scheduled for infrarenal aortic bypass surgery the cardiovascular effects of two anaesthetic regimes were investigated prior to surgery. A Swan-Ganz-catheter was used for haemodynamic measurements. These patients, having been randomized into two groups, were optimally volume loaded (PCWP 10 mmHg) before anaesthesia. In 24 patients a thoracic epidural was induced with 12-15 ml 0.25% plain bupivacaine. When segmental anaesthesia had extended from T4/5 to L1/2 general anaesthesia was additionally applied (flunitrazepam 1.5-2 mg, pancuronium bromide 0.1 mg/kg). In 26 patients neuroleptanaesthesia was induced (droperidol 0.1-0.2 mg/kg, fentanyl 0.01 mg/kg, pancuronium bromide 0.1 mg/kg, and thiopentone 100-150 mg. Haemodynamic measurements were made before injection into the epidural catheter, after complete spread of anaesthesia, before commencing general anaesthesia and 10-15 min thereafter. Results: Neither of the two procedures were associated with severe haemodynamic alterations. In the epidural group HR fell slightly during latency of complete spread and increased to the same extend following general anaesthesia. The epidural caused MAP (104 to 88 mmHg), mean PAP (20 to 14 mmHg), PCWP (10 to 7.5 mmHg), and RAP (4.5 to 2.5 mmHg) to decrease moderately but no further changes were effected by the subsequent general anaesthesia. SVR and PVR were not influenced by either epidural or by general anaesthesia. CI (3.6 to 3.41 . min-1 . m-2), LVSWI (67 to 52 p . m-1), and cardiac minute work index (55 to 40 J . min-1 . m-2) decreased during latency of complete spread but were no further influenced by general anaesthesia. The haemodynamic changes of neuroleptanaesthesia were almost identical to those of the combined epidural-general anaesthesia. For the operation which followed, a continuous infusion of 0.125 per cent plain bupivacaine (0.25 ml/kg X h) via epidural catheter (in combination with N2O/O2-anaesthesia) was sufficient for complete analgesia in the epidural group. These findings lead to the conclusion that a small bolus volume and a low concentration of bupivacaine result in good anaesthesia while avoiding serious haemodynamic alterations. 相似文献

The effect of lumbar epidural analgesia and of general anaesthesia on the peroperative velocity of flow in the femoral vein was measured with Doppler ultrasound technique in 38 patients undergoing retropubic prostatectomy. The patients were randomly allocated to the epidural or the general procedure. The 125I-fibrinogen test was used to detect deep vein thrombosis (DVT). Epidural analgesia was associated with a significant (ca. 120%) increase in the femoral venous flow velocity. The peak flow showed a moderate (47%) increase, whereas the minimum flow was greatly increased (188%). The increase was significant already 2 min after induction of the analgesia and the rate continued to rise for about 11 min. General anaesthesia significantly reduced the flow velocity in the femoral vein. Immediately after induction of the anaesthesia the velocity approached zero, but gradually rose, and after about 8 min was stabilized at level 40% below the preoperative velocity. The peak flow velocity in all patients of this group fell by 24 to 40%. Only 2 of 17 patients with epidural analgesia, but 11 of 21 with general anaesthesia had postoperative DVT. In the 11 patients with DVT the mean minimum velocity of flow was decreased (by 85%), but in the 10 without DVT it was increased (by 175%). The difference was not statistically significant. Increased velocity of flow in the femoral vein, especially of minimum flow, seems to counteract development of DVT. 相似文献

Intra- and post-operative blood loss and haemodynamics in total hip replacement when performed under lumbar epidural versus general anaesthesia 总被引:1,自引:0,他引:1
The effects of lumbar epidural anaesthesia and two types of general anaesthesia on blood loss and haemodynamics during and after hip replacement were compared in three groups of patients. One group (n = 14) received continuous lumbar epidural anaesthesia, another group (n = 10) was given inhalational anaesthesia and spontaneous breathing after endotracheal intubation, and the third group (n = 14) received artificial ventilation after intubation and pancuronium and fentanyl intermittently i.v. Intra-operative blood loss in patients under epidural anaesthesia was 950 +/- 300 ml (mean +/- SD) and blood loss during the following 24 h-i.e. as long as the epidural anaesthesia was maintained-was 370 +/- 80 ml. These figures were significantly lower than the intra- and post-operative blood losses in patients under general anaesthesia with narcotics as post-operative pain treatment: 1140 +/- 200 ml (inhalational anaesthesia) followed by 480 +/- 70 ml and 1540 +/- 340 ml (artificial ventilation) followed by 500 +/- 110 ml. The intra-operative blood loss in the general anaesthesia group with spontaneous breathing was significantly smaller than the blood loss in the artificially ventilated group, whereas the post-operative blood loss in the two general anaesthetic groups was similar. Haemodynamic differences explain these differences in blood loss. Thus epidural anaesthesia induced hypotension on the arterial and venous sides. Intra-operatively, inhalational anaesthesia also induced hypotension on the arterial and venous sides compared with general anaesthesia using artificial ventilation. Post-operatively, the general anaesthesia groups behaved haemodynamically similarly and no differences in blood loss were seen. The reduction in blood loss, notably associated with lumbar epidural anaesthesia, is beneficial in decreasing the hazard and cost of blood transfusion. 相似文献

人工全髋关节置换术后下肢深静脉血栓形成的多因素分析 总被引:7,自引:3,他引:4
目的:分析影响人工全髋关节置换术(THA)后下肢深静脉血栓形成(DVT)的危险因素。方法:对98例(112个关节)人工全髋置换术术后DVT发生情况进行分析。其中男55例,女43例;平均年龄59.12岁(41~81岁)。术前及术后7~10d均用彩色多普勒检查双下肢深静脉血流通畅情况及DVT的发生。对17项临床因素与人工关节置换术后DVT形成的相关性进行了分析。结果:术后发生DVT41例,DVT发生率为41.84%(41/98),其中无症状DVT患者占58.54%(24/41)。经Logistic多因素回归分析,与DVT相关的因素有5个,其中年龄、肥胖及肢体延长大于2cm使术后发生DVT的风险分别增加到1.952、3.349及7.376倍(P<0.05);硬膜外麻醉和踝泵练习使术后发生DVT的可能性减少到原来的0.132和0.265(P<0.01)。结论:年龄、肥胖及肢体延长大于2cm是人工关节置换术后发生DVT的危险因素,而硬膜外麻醉和踝泵练习是减少术后发生DVT的保护因素。关节置换术后无症状DVT的大量存在,提示术后最好常规行双下肢彩色多普勒检查,一旦有DVT发生,及时治疗,防止发生致命性肺栓塞。 相似文献
