ABSTRACT
Background: Surgical removal of impacted lower third molars is a common oral surgical procedure, generally followed by moderate to severe postoperative pain. Transdermal drug delivery as a concept offers interesting possibilities for postoperative pain control. Aims and Objectives: to evaluate and compare the degree of post-operative analgesia, patient compliance and frequency of adverse events between transdermal ketoprofen patch and transdermal fentanyl patch following third molar extraction. Methods: Total 7 patients aged 18-65 years with impacted mandibular third molar teeth were included in the study. The study drugs transdermal patches of fentanyl and ketoprofen was applied one hour before the surgical procedure on the skin, preferably in an area devoid of any hair. The selected mandibular third molar tooth of either of the side was extracted in the first appointment using an aseptic protocol. Every patient was given a Verbal Pain Intensity and Pain Relief chart ( both 5- point scales with values 0-4 ) for assessing pain intensity and pain relief for all the three post-operative days. Results: During the first four hours of operative day, the difference observed between the two groups was not found to be statistically significant (p=0.881). Whereas during the first eight hours of operative day the difference observed between the two groups was not found to be statistically significant (p=0.141). During the first twelve hours of operative day, the difference observed between the two groups was not found to be statistically significant (p=0.276). At the end of operative day, the difference observed between the two groups was found to be statistically significant (p=0.048). Conclusion: Transdermal fentanyl patch was more effective for immediate pain relief than transdermal ketoprofen patch for pain control following removal of mandibular impacted third molars.
ABSTRACT
Background: Most parturient women request analgesia, of which, there are two types; opioids and non-opioids. Opioids include morphine and meperidine, while non-opioids, which are milder forms of painkillers, include acetaminophen (paracetamol) and non-steroid anti-inflammatory drugs. The major concerns associated with opioids are the risk of neonatal respiratory depression, the cost and availability.Methods: The aim of this study was to compare the efficacy and safety of paracetamol versus meperidine for intra-partum pain relief. A total of 92 primiparous singleton term pregnant women were randomly allocated to receive intravenous paracetamol (1000 mg), or intramuscular meperidine (50 mg), at the beginning of the active phase of labor. The primary outcome was the labor pain perception, assessed using the visual analogue scale (VAS), at baseline, 15, 30, 60 and 120 minutes after administration of the drug.Results: Women of both groups showed significant reduction of the VAS after administration of the medication. There were no differences between both groups regarding the mode of delivery and the durations of the first or second stages of labor. However, meperidine was associated with higher rates of dizziness and nausea/vomiting. The 1-min Apgar scores were significantly lower in meperidine group. However, there were no differences in the 5-min Apgar score, need for neonatal resuscitation or neonatal respiratory distress.Conclusions: intravenous paracetamol as analgesia during labor is effective with no fetal or maternal adverse effects. Its use should have more chance for intrapartum pain relief. Additionally, it can be used as adjuvant with other types of analgesics.
