目的:探析口腔种植牙术后肿胀疼痛采取新癀片进行治疗的效果及对炎性因子的影响。方法:选取2015年1月至2019年12月北京中医药大学东直门医院收治的口腔种植牙术后肿胀疼痛患者300例作为研究对象,按照随机数字表法随机分为对照组和观察组,每组150例,对照组采用红霉素治疗,观察组采用新癀片联合红霉素治疗,比较2组患者术后肿胀和术后疼痛持续时间、牙槽骨吸收量、种植牙功能、种植体唇侧骨厚度、周围边缘骨吸收量、炎性反应因子水平、治疗优良率等指标。结果:与对照组比较,观察组术后肿胀持续时间、术后疼痛持续时间明显较短(P<0.05);观察组种植牙功能评分等明显高于对照组(P<0.05);观察组种植体唇侧骨厚度、周围边缘骨吸收量与对照组比较有明显差别(P<0.05);观察组CPR、IL-6、PCT等炎性反应因子水平明显较低(P<0.05);观察组治疗总有效率明显高于对照组(P<0.05)。结论:口腔种植牙术后肿胀疼痛应用新癀片进行治疗,能获得较为理想的效果,改善炎性反应因子水平,有着极大的推广价值。 相似文献

Purpose: The purpose of this study was to determine the effectiveness of an individualized physical rehabilitation programs aimed at improving respiratory function in women with post-mastectomy syndrome. Methods: In a randomized controlled trial 50 women with post-mastectomy syndrome were enrolled in the experimental group (EG, n = 25) or the comparison group (CG, n = 25). The program for the EG included: aqua aerobics (i.e. aqua jogging, aqua building, and aqua stretching); conditional swimming; and recreational aerobics. The program for the CG included: conditional swimming and Pilates exercises. Both intervention groups attended individualized physical rehabilitation programs three times per week for 48 weeks. The primary outcome measure was spirometry of the patients measured before, 6 and 12 months after the intervention. Results: This study demonstrated that most of the respiratory function parameters increased significantly in both groups over the year of exercise training. After the year of training the individualized physical rehabilitation program for the EG was significantly better (p < 0.01) as compared with the CG, except for inspiratory reserve volume and maximal voluntary ventilation, which were not statistically different. Conclusions: The results of the study suggest that individual programs of physical rehabilitation could be considered effective for the improvement of respiratory function of the patients with post-mastectomy syndrome. The results obtained could serve as a basis for more widespread clinical program development. 相似文献

Serum lactate is a non-specific marker of tissue hypoperfusion. Elevated serum lactate is used in the differential diagnosis of acute intestinal ischemia. Although this practice is controversial, in the absence of other validated markers lactate is still used because of its high sensitivity.We present the cases of two patients who developed acute mesenteric ischemia as a post-surgical complication. The patients reported moderate abdominal pain —a non-specific symptom in the postoperative context— and tests showed progressively increasing serum lactate levels, which facilitated suspicion and subsequent diagnostic confirmation through an imaging test.These cases highlight the physiopathological importance of lactate elevation in the perioperative context and of performing a differential diagnosis of its possible causes, including mesenteric ischemia. Although the outcome was negative in the first case, early suspicion allowed us to make an effective diagnosis and administer appropriate treatment in the second patient. 相似文献

ObjectivesTo evaluate operative comfort and stress in patients undergoing stapedotomy for otosclerosis under local versus general anesthesia.Material and methodsConsecutive otosclerosis patients managed over a 9-month period responded to 3 validated questionnaires to assess peri- and post-operative comfort: Glasgow Benefit Inventory, Cohen's Perceived Stress Scale and the Posttraumatic Stress Disorder Checklist Scale. These results and audiometric data were compared between local and general anesthesia groups.ResultsTwenty-one patients were included in the local anesthesia group and 7 in the general anesthesia group, after exclusion of patients with history of otosclerosis surgery. There was no significant inter-group difference on Glasgow Benefit Inventory (P = 0.38) or Posttraumatic Stress Disorder Checklist Scale (P = 0.86). Perceived Stress Scale scores were higher in the general anesthesia group (P = 0.038). In total, 67% of patients reported no discomfort under local anesthesia, and 86% were ready to undergo the procedure under local anesthesia again. There were no significant differences in postoperative symptoms, or in air-bone gap ≤ 10 dB (local anesthesia 81%, general anesthesia 71%; P = 0.156).ConclusionsLocal anesthesia in otosclerosis surgery did not increase stress or postoperative symptoms compared to general anesthesia. Audiometric results were not affected by type of anesthesia. 相似文献
