Background
A retrospective review of 1,147 patients who received epidural analgesia (EA) in surgical wards from January 2008 to December 2009 to determine the prevalence of early ambulation and assess the efficacy and safety of EA for postoperative pain management.Aim
Outcome measures were the prevalence of ambulation, pain scores at rest/movement and adverse events.Methods
Patients (N = 1,147) who received postoperative EA between January 2008 and December 2009 were included. Motor function was assessed using the Bromage scale. Ambulation was defined as: Day 1: mobilisation from bed to chair, walking on the spot, taking a few steps, thereafter walks of increasing duration and distance at least twice daily. Pain scores were measured using the verbal numerical rating scale (0–10), ≤4 signifying successful analgesia. Daily assessments and data recordings were performed by clinical nurse specialists (CNSs) using standardised charts. Data collected included patient demographics, surgical procedure, ambulation achieved, pain scores at rest/movement and adverse events. The data was analysed using Microsoft Excel®.Results
The prevalence of ambulation was 88 % and this was maintained for the duration of EA. Ninety-eight percent of patients reported pain scores of ≤4 at rest and 88 % reported pain scores of ≤4 on movement. Adverse events included motor block 12 %, nausea 9 %, hypotension 8 %, catheter dislodgement 3.8 %, leakage from insertion site 1.6 %, decubitus ulcers 0.58 % and infection 0.001 %. Mean duration of EA was 4 days.Conclusions
Ward-based EA facilitates early ambulation, provides excellent postoperative pain relief and is associated with low prevalence of adverse events. 相似文献5.

Effect of pre-electroacupuncture on p38 and c-Fos expression in the spinal dorsal horn of rats suffering from visceral pain 总被引:1,自引:0,他引:1
Background Acupuncture is an effective way to relieve pain, but the mechanism by which electroacupuncture (EA) decreases the visceral pain state still remains unclear. This study aimed to evaluate the effects of pre-electroacupuncture on pain behaviors, p38 phosphorylation, and c-Fos protein and mRNA expression in both the colonic wall and spinal dorsal horn of rats suffering from visceral pain. This study also investigated the probable signaling regulatory mechanism of the analgesic effect induced by electroacupuncture. Methods All rats were randomized into the control (Con) group, the Con+EA group, the visceral pain (VP) group, and VP+EA group (n=8 for all groups). The visceral pain model was established using 40 ul of 5% formalin solution injected into the colon of rats. EA was applied to the bilateral Jiaji acupoints for 20 minutes before application of visceral pain. Parameters for EA were set at a continuous wave (20 Hz) and intensity where the rats shook their whiskers but did not scrabble (≤1 mA). The visceral pain score was recorded and the expressions of p38 and c-Fos protein were detected using Western blotting. Real-time quantitative PCR was also used to determine the expression of c-Fos mRNA. Results Rats in the VP group immediately presented with obvious visceral pain behaviors after being injected with formalin. p38 activity and c-Fos protein and mRNA expression in both the colonic wall and spinal dorsal horn were higher in the VP group than in the Con group (P 〈0.05). By contrast, visceral pain behaviors were delayed in rats from the VP+EA group. p38 activity and c-Fos protein and mRNA expression were lower in the VP+EA group than that in the VP group (P〈0.01). Conclusions Pre-electroacupuncture of the Jiaji acupoint has prophylactic analgesic effects on rats suffering from visceral pain. The p38 signal transduction pathway may be partly involved in the regulatory mechanism of this analgesic effect. 相似文献

BACKGROUND: The analgesic efficacy and bioavailability of 30 mg intramuscular ketorolac was studied in 24 patients with severe or very severe postoperative pain. METHODS: Pain and pain relief were determined by a five-point verbal rating scale and data were submitted to a probability analysis. Ketorolac plasma levels were determined by high-performance liquid chromatography. RESULTS: Two patients chose not to finish the study; 22 patients completed the study achieving at least good pain relief. Of these 22 patients, 13 reached complete pain relief. Ketorolac was rapidly absorbed. Notwithstanding, pain relief increased gradually, showing considerable delay with regard to plasma concentrations. Analysis of the probability-time curves revealed that 25% of the patients obtained moderate pain relief at 7 min after ketorolac administration, 50% at 11 min, 75% at 29 min, and 95% at 60 min. Good pain relief was achieved in 25, 50, and 75% of the patients at 1.1, 1.8, and 2.7 h, respectively. Complete pain relief was achieved in 25% and 50% of the patients at 2.6 h and 3.7 h, respectively. The probability of exhibiting an acceptable pain relief in responsive patients for more than 5 h was 0.97. No serious side effects were detected. CONCLUSIONS: Results show that 30 mg intramuscular ketorolac is an adequate treatment for postoperative pain in the Mexican population. Therefore, the use of higher doses is not justified. Due to gradual installation of analgesia, administration of additional analgesic medication before 1 h is not recommended. 相似文献

Subjective symptomatic improvement is experienced by 90% of patients after coronary bypass surgery. Objective exercise testing reduces this incidence to 70%. An analysis of the multifactorial genesis of pain relief based on data of non-randomized trials reveals that graft patency plays a dominant but not unique role in causing improved symptomatology. In a number of cases, intra-operative myocardial infarctions seem to explain the pain relief but may also have opposite effects. Changes in left ventricular function operate bidirectionally but data on this variable in relation to changes in symptomatology are not amenable for detailed analysis. Progression in native vessel lesions apparently opposes pain relief and has its greatest impact in connection with graft closure. Residual post-operative angina is evidently related also to incomplete revascularization. 相似文献

实验用大鼠76只,用辐射热-甩尾法测痛,以电针后痛阈变化的百分率评价镇痛效应;用放射免疫分析法测定脑内L-Enk含量。发现脑室注入三肽-促甲状腺素释放激素(TRH)后,能显著降低电针镇痛效果;提高丘脑内L-Enk含量,但痛阈与脑内L-Enk含量的变化无相关关系。本文证明,TRH在电针镇痛过程中是对抗作用。已知针刺镇痛与脑内多种神经质和肽类有关,在不利于针刺镇痛的因素中,TRH是新添的“一员”。 相似文献

Objectives:To assess the effect of bupivacaine application following pulsed radiofrequency (PRF) ablation on trigeminal facial pain.Methods:A total of 73 patients with trigeminal facial pain refractory to conservative therapy were randomized into 2 groups. Group I subjects underwent PRF ablation procedure, followed by the injection of 1 ml of bupivacaine. Whereas, Group II underwent the same procedure followed by the injection of 1 ml of normal saline. Pain relief duration, the time of onset of pain relief, and analgesic effect evaluated by numerical pain rating scale were considered as outcomes.Results:Thirty-nine patients in Group I and 34 in Group II. The duration of pain relief in the 2 groups was comparable (5 months in Group I vs. 6 months in Group II, p=0.53). The onset of pain relief in the patients of Group I was shorter than Group II (0 days vs. 4.5 days, p<0.001). The binary logistic regression analysis revealed that the application of bupivacaine alone had a significant effect on the reduction of the intake of medications (p<0.05).Conclusion:In situations involving patients who require rapid pain relief, bupivacaine injection following PRF ablation can be employed to provide immediate relief without subjecting the patients to the risks associated with major complications. 相似文献
