The purpose of this systematic review was to determine the analgesic efficacy and adverse effects of ibuprofen in comparison with other traditional non-opioid analgesics after third molar surgery. A total of 17 full texts were identified in PubMed and assessed using the Cochrane Collabo-ration’s risk of bias tool by two independent researchers. The sum of pain intensity differences, total pain relief, the overall evaluation, the number of patients requiring rescue analgesics, and adverse effects were collected. Data were analyzed using the Review Manager Software 5.3. for Windows. A total of 15 articles met the criteria. The qualitative and quantitative analysis showed that ibuprofen is more effective to relieve post-operative dental pain than acetaminophen, meclofenamate, aceclofenac, bromfenac, and aspirin. Moreover, ibuprofen and traditional non-steroidal anti-inflammatory drugs have a similar safety profile. In conclusion, ibuprofen 400 mg appears to have good analgesic efficacy and a safety profile similar to other traditional non-steroidal anti-inflammatory drugs after third molar surgery.
OBJECTIVES:: Postoperative pain can contribute to increased risk for complications and lengthened hospital stays. The objective was to analyze the effects of perioperative vitamin C supplementation on postoperative pain and the development of complex regional pain syndrome I (CRPS I) in patients undergoing surgical procedures.
METHODS:: A systematic review of published literature was performed through April 2014. References from relevant studies were scanned for additional studies. Results were screened for relevance independently, and full-text studies were assessed for eligibility. Reporting quality was assessed using a modified Newcastle-Ottawa Scale.
RESULTS:: The search strategy yielded 710 studies, of which 13 were included: seven on postoperative pain and six on CRPS I. In the final analysis, one relevant study found a reduction in postoperative morphine utilization after preoperative vitamin C consumption, while another showed no difference in postoperative pain outcomes between the vitamin C and control groups. A meta-analysis of three applicable CRPS I studies showed a decrease in postoperative CRPS I after perioperative vitamin C supplementation (relative risk (RR)=2.25; tau=0).
DISCUSSION:: There is moderate level evidence supporting the use of a 2 g preoperative dose of vitamin C as an adjunct for reducing postoperative morphine consumption, and high level evidence supporting perioperative vitamin C supplementation of 1 g per day for 50 days for CRPS I prevention after extremity surgery. Additional studies are necessary to increase the level of evidence to determine the overall effectiveness and optimum dosage of vitamin C.
Complex regional pain syndrome (CRPS) is a devastating condition often seen after foot and ankle injury and surgery. Prevention of this pathology is attractive not only to patients but also to surgeons, because the treatment of this condition can be difficult. We evaluated the effectiveness of vitamin C in preventing occurrence of CRPS in extremity trauma and surgery by systematically reviewing relevant studies. The databases used for this review included: Ovid EMBASE, Ovid MEDLINE, CINAHL, and the Cochrane Database. We searched for comparative studies that evaluated the efficacy of more than 500 mg of daily vitamin C. After screening for inclusion and exclusion criteria, we identified 4 studies that were relevant to our study question. Only 1 of these 4 studies was on foot and ankle surgery; the rest concerned the upper extremities. All 4 studies were in favor of this intervention with minimal heterogeneity (Tau(2) = 0.00). Our quantitative synthesis showed a relative risk of 0.22 (95% confidence interval = 0.12, 0.39) when daily vitamin C of at least 500 mg was initiated immediately after the extremity surgery or injury and continued for 45 to 50 days. A routine, daily administration of vitamin C may be beneficial in foot and ankle surgery or injury to avoid CRPS. Further foot and ankle specific and dose-response studies are warranted.
BACKGROUND: We have reviewed the analgesic efficacy of cyclooxygenase-2 (COX-2) inhibitors compared with traditional non-steroidal anti-inflammatory drugs (NSAIDs), different COX-2 inhibitors, and placebo in post-operative pain.
METHODS: Randomized controlled trials were evaluated. Outcome measures were pain scores and demand for supplementary analgesia 0-24 h after surgery.
RESULTS: Thirty-three studies were included in which four COX-2 inhibitors, rofecoxib 50 mg, celecoxib 200 and 400 mg, parecoxib 20, 40 and 80 mg, and valdecoxib 10, 20, 40, 80 mg were evaluated. Ten of these studies included 18 comparisons of rofecoxib, celecoxib, or parecoxib with NSAIDs. Rofecoxib 50 mg and parecoxib 40 mg provided analgesic efficacy comparable to that of the NSAIDs in the comparisons, and with a longer duration of action after dental surgery but possibly not after major procedures. Celecoxib 200 mg and parecoxib 20 mg provided less effective pain relief. Four studies included five comparisons of rofecoxib 50 mg with celecoxib 200 and 400 mg. Rofecoxib 50 mg provided superior analgesic effect compared with celecoxib 200 mg. Data on celecoxib 400 mg were too sparse for firm conclusions. Thirty-three studies included 62 comparisons of the four COX-2 inhibitors with placebo and the COX-2 inhibitors significantly decreased post-operative pain.
CONCLUSION: Rofecoxib 50 mg and parecoxib 40 mg have an equipotent analgesic efficacy relative to traditional NSAIDs in post-operative pain after minor and major surgical procedures, and after dental surgery these COX-2 inhibitors have a longer duration of action. Besides, rofecoxib 50 mg provides superior analgesic effect compared with celecoxib 200 mg.
