Purpose
To evaluate the analgesic efficacy of a diclofenac transdermal patch with diclofenac intra muscular injection in the immediate postoperative period in patients undergoing major oral surgical procedures.Materials and Methods
Subjects who underwent bijaw surgeries for surgical correction of various dentofacial deformities were included. Sixty such patients who belonged to the above entity were randomly categorized into two groups from Jan 2012–Aug 2015. Group A (study group) received a single dose of 100 mg transdermal diclofenac patch, Group B (control group) received 75 mg intramuscular diclofenac and tramadol HCl 2 mg/kg body wt was used as rescue analgesic in the immediate post operative phase. The analgesic efficacy of the drugs are evaluated on periodic patient’s perception of pain in the immediate postoperative phase of 2nd, 6th, 12th, 24th and 48 hours.Results
The mean VAS score in Group A was 2, mean duration of analgesia was 16 h 9 min, and in Group B the mean VAS score was 4, duration of analgesia was 8 h and 4 min. Tramadol HCl was given as rescue analgesia in 22 % (6) of patients belonging to Group A. None of the patients from both the groups reported local complications.Conclusion
A noninvasive application of a single dose of 100 mg transdermal diclofenac patch is more effective than intramuscular diclofenac (75 mg) in the immediate post operative phase, without any significant side-effects is a novel ingress into the field of oral and maxillofacial surgery for post operative pain management.13.

The aim of this pilot study was to evaluate pre-emptive analgesia using the combination tramadol plus meloxicam compared with each individual drug alone for the reduction of pain after extraction of third molars. Fifty-one patients were randomised into three groups (n=17 in each), using a series of random numbers: the first group was given tramadol 25mg and meloxicam 7.5mg; the second tramadol 50mg, and the third meloxicam 15mg, all intramuscularly. Treatments were prepared in identical syringes by an independent investigator and were given immediately. The teeth were removed 50min after the analgesics had been given. Intensity of pain, consumption of analgesics, and adverse effects were evaluated. The intensity of pain was evaluated using a visual analogue scale (VAS) and the area under the curve of the VAS showed significant differences amongst the groups. In conclusion, the study showed that the combination of tramadol 25mg and meloxicam 7.5mg had an analgesic effect similar to that of meloxicam 15mg, but both were better than tramadol 50mg for relief of pain after the extraction of mandibular third molars. 相似文献

Background: Butorphanol tartrate, a mixed synthetic agonistantagonist opioid analgesic has been used for management of postoperative pain in minor and major surgical procedures.(14,20) Tramadol hydrochloride is a centrally acting opioid which is effectively used in postoperative pain in various minor and major surgeries. Materials and methods: Twenty subjects selected randomly received butorphanol tartrate 1 mg intramuscular and 20 subjects received tramadol hydrochloride 50 mg intramuscular after the removal of mandibular third molars. Time of injection, amount of anesthetic injected, duration of surgery, adverse effects were recorded.(21) Results: The mean amount of LA administered in butorphanol group was 2.6450 ml and in tramadol group was 2.640 ml respectively, the mean duration for surgery was 56.75 and 53.5 minutes for butorphanol and tramadol groups respectively which was statistically not significant. Pain assessment was done with VAS which showed mean of 19.2 and 15.5 mm (p = 0.001) which was significant for butorphanol and tramadol respectively after 12 hours. The mean time for rescue medication requirement was 5.9 hours (for tramadol) and 8.4 hours (for butorphanol). Effective analgesic activity was seen by butorphanol 1 mg intramuscular then tramadol 50 mg. Conclusion: Butorphanol 1 mg was more effective than tramadol 50 mg in respect to postoperative analgesia.

Introduction
This study aims to compare two routine procedures of sedation, with and without intravenous adjunct analgesia, in third molar surgery regarding postoperative pain and consumption of analgesics.Material and methods
In a randomized, controlled, single-blinded procedure, 87 men and women aged 18–44 years were divided into two treatment groups, midazolam?+?tramadol (M?+?T) and midazolam?+?saline (M?+?S), and one control group (C), with no additional medication. After removal of a third lower molar, patients recorded postoperative pain on a visual analog scale (VAS) and consumption of analgesics during the first day after surgery.Results
Time from the end of operation until first rescue pill (400 mg Ibuprofen tablet) differed significantly between the M?+?S group (193 min) and the C group (110 min) (p?=?0.001) as well as the M?+?T group (157 min) and the C group (p?=?0.049). The study did not show any significant reduction of postoperative pain, VAS, after third molar surgery in patients who received adjunct pre-emptive intravenous administration of 1 mg/kg tramadol under midazolam sedation.Discussion and conclusion
The lack of significant difference between the study and placebo groups indicates that tramadol at 1 mg/kg might be an insufficient dose, though the suitability for tramadol in oral and maxillofacial surgery has already been settled in other studies. 相似文献19.
目的:探讨七氟醚吸入麻醉在婴儿唇裂术后拆线的可行性。方法:选择年龄小于1岁唇裂术后拆线患儿60例,随机分为氯胺酮肌注组(K),七氟醚吸入组(S)和七氟醚复合笑气吸入组(SN)。K组给予肌注氯胺酮5mg/kg,咪唑安定0.05mg/kg,阿托品0.01mg/kg;S组以8%七氟醚,氧流量6L/min面罩吸入诱导;SN组以8%七氟醚,复合笑气4L/min,氧气2L/min吸入诱导,患儿入睡后改为4%七氟醚,氧流量3L/min维持,吸入2min后开始拆线。术中常规监测患儿HR,SpO2。记录患儿诱导时间、苏醒时间、术中发生体动情况及术中呼吸抑制、分泌物增多等并发症情况。结果:S组和SN组的诱导时间、苏醒时间短于K组,2组间差异无统计学意义。S组和SN组患儿术中体动的发生率小于K组。3组均有患儿发生舌后坠和分泌物增多,但差异无统计学意义。结论:七氟醚吸入诱导和苏醒时间均比肌注氯胺酮麻醉迅速,能够更加安全有效地用于唇裂婴儿术后拆线;复合笑气吸入不能缩短七氟醚吸入麻醉的诱导和苏醒时间。 相似文献
