Filter by:Numerous instrumentation techniques have been suggested for the nonsurgical retreatment of teeth with primary failure of endodontic therapy in laboratory studies. However, there is limited clinical evidence about those different techniques. The objective of this study is to compare the prevalence and intensity of postoperative pain, as well as the success rate after endodontic retreatment with hand or engine-driven reciprocating instrumentation. A randomized clinical trial will be performed, considering two comparison groups: hand preparation with stainless steel instruments or engine-driven reciprocating preparation with the Reciproc NiTi System (VDW, Munich, Germany), to verify which technique would lead to lower postoperative pain levels and higher endodontic success rates. Secondary outcomes related to technique efficiency will be also registered, evaluating the capacity of filling material removal and the time spent on the clinical procedures. Eighty individuals who need endodontic retreatment in single-rooted teeth will be selected (n=40/group). Endodontic reintervention will be carried out in two visits. Periapical radiographs taken after root filling removal protocols will be transferred to an image analysis software. Then, the percentage of remaining filling material in relation to the total area of the root canal will be evaluated. The clinical time spent with the removal procedure protocol will be registered, in minutes, by a digital stopwatch. After each visit, postoperative pain will be assessed using a numerical rating scale. The record of pain and analgesic drug intake will be performed in 12, 24, 48 hours and 7 days after the clinical procedures. Success rates will be evaluated after 3, 6, 12 and 24 months, through clinical and radiographic examination, considering the Periapical Index, a 5-point score system. Data of both groups (percentage of remaining debris, operating time, postoperative pain, clinical and radiographic success) will be analyzed for normality by the Shapiro-Wilk test. Assuming normal distribution, the data will be compared by t test. Pearson's correlation coefficient will be applied to detect possible correlations between the evaluated outcomes. Differences will be considered significant at P=0.05.
The overall research plan is PECS/SAP blocks with liposomal bupivacaine improve the Overall Benefit Analgesia Score averaged over the postoperative days 1, 2, and 3. A 20% reduction on geometric means (i.e., true ratio of geometric means of 0.80) in OBAS will be considered the minimal clinically important benefit.
Transversalis fascia plane block is a regional anesthesia technique described ten years ago. Its use for many indications has been identified by case reports in the literature. As the investigators have considered that transversalis fascia plane block could be efficacious for providing postoperative analgesia in the cesarean section, the investigators have implemented the application of this blockade into practice at the clinic. The main purpose of this study is to evaluate the analgesic effect of ultrasound-guided bilateral transversalis fascia plane block in cesarean section.
The aim of this study was to assess the efficacy of bilateral ESPB on postoperative analgesia in patients undergoing total abdominal hysterectomy under general anesthesia.
the purpose of this study is monitoring Postoperative pain in Children Aged from 3 to 5 years following Full mouth Dental Rehabilitation under General Anesthesia
Retrospective Evaluation of Erector Spinae Plane Blocks
Lichtenstein herniorrhaphy still remains one of the most often performed inguinal hernia repair techniques. It is frequently associated with acute postoperative and chronic pain. Due to insufficient effect of non-steroidal anti-inflammatory drugs, they are often overdosed. However opioids have many side effects. Interventional treatment, such as transversus abdominis plain (TAP) block requires an additional intervention and has relatively short effect, also could not be applied in outpatient conditions. The hypoalgesic effect of transcutaneous electric nerve stimulation (TENS) is well known for many years, but effectiveness during postoperative period is still controversial and maybe therefore didn't come to daily practice. However it could be a promising part of multi-modal pain treatment for hernia patients. This study analyse the hypoalgesic effect of TENS and its impact on hernia specific quality of life (QoL) after Lichtenstein hernia repair. Aim#1 To determine whether use of TENS is effective for acute postoperative pain relief. Aim#2 To determine whether use of TENS have impact on hernia specific QoL in early and late postoperative period. Aim#3 To identify factors associated with effectiveness/ineffectiveness of TENS procedures. Aim#4 To determine whether a psychological condition (depression, anxiety and pain catastrophisation) is somehow associated with TENS effectiveness.
This study is a comparison of the analgesic efficacy of transversus abdominis plane (TAP) blocks with ropivacaine bolus plus continuous ropivacaine infusion via catheters versus single shot TAP blocks with liposomal bupivacaine.
The purpose of this study is to assess pharmacokinetics of liposomal bupivacaine (Exparel) after multilevel intercostal injections of this local anesthetic for pain control during and after thoracoscopic surgeries. The specific aim of this study is to evaluate plasma concentration of bupivacaine after intraoperative intercostal injections of 266 mg of liposomal bupivacaine and compare it to plasma concentrations of bupivacaine after intercostal injections of 2mg/kg of 0.5% plain Bupivacaine with maximal dose of 30 ml or 150 mg. The hypothesis of the study is that plasma concentration of bupivacaine after intercostal injections of 266 mg of liposomal bupivacaine will be similar to concentrations after injections of plain bupivacaine, and will remain below the toxic level threshold range of 2000-3000 ng/mL (2-3 mg/L) at which central nervous system and cardiovascular adverse events would be expected to occur. The secondary objective is to evaluate if intercostal injections of 266 mg of liposomal bupivacaine will significantly reduce opioid consumption and postsurgical pain, within the first 48 hours and up to 3 months after minimally invasive thoracic surgeries, to determine if both acute and chronic post-thoracotomy pain can be decreased by intraoperative intercostal injections of liposomal bupivacaine. Additionally, the rate of pneumonia, the rate of atrial fibrillation and length of hospital stay will be assessed as secondary outcomes after thoracic surgeries. These outcomes can be affected by the level of postoperative pain and inflammation. Significance of this study: If positive, the results of this research have the potential to significantly improve pain management after thoracoscopic surgery. Based on prior experience, prolonged analgesia after liposomal bupivacaine injection is safe, and may help reduce perioperative opioid consumption and decrease opioid related complications. It will improve patient comfort, eliminate need for indwelling neuraxial catheters and risks associated with them.
Subepithelial connective tissue graft (SCTG) has greater predictability for root coverage and causes minimal discomfort to patient. Although donor site heals with primary intention causing less scar tissue, in some different harvesting procedures primary flap closure may not be achieved due to nature of thick palatal tissues. Some potential complications may occur at donor site such as: necrosis of graft and palatal site, pain, excessive hemorrhage, protracted discomfort, donor site infection and in some cases donor site paresthesia. Platelet rich fibrin (PRF) is a platelet concentrate obtained by a simple procedure that does not require biochemical blood involvement.Based on the known biological effects of PRF, the aim of this study is to evaluate the PRF in the management of soft tissue donor sites in term of bleeding and pain sensation, and to observe the changes in tissue healing after a subepithelial connective tissue graft procedure at palatal donor site.
