This is a research study to compare how long injectable pain medications (anesthetics) commonly used in dermatologic surgery are effective for. This study will compare a short-acting anesthetic, lidocaine with epinephrine, to one of two long-acting anesthetics (ropivacaine or bupivacaine). This study will also directly compare the duration of actions of ropivacaine and bupivacaine. The investigators hypothesize that the duration of anesthesia of short-acting anesthetics will not differ significantly from long-acting anesthetics at a single site and there will not be a significant difference between the two long-acting anesthetics at a single site.
Abdominal wall blocks are frequently used as part of multimodal analgesia for pain control after abdominal surgery. There are studies using the Transversus Abdominis Plane Block for postoperative pain control in laparoscopic cholecystectomies. In this study, the investigators aimed to compare the advantages of these two methods by applying the Transversus Abdominis Plan Block for postoperative pain control after laparoscopic cholecystectomy with the help of postoperative USG and laparoscopy during surgery.In this study, the investigators aimed to compare the advantages of these two methods by applying the Transversus Abdominis Plan Block for postoperative pain control after laparoscopic cholecystectomy with the help of postoperative USG and LAPAROSCOPY during surgery.
As of October 2019, when the investigators received the approval of the ethics committee, patients who were decided to undergo kyphoplasty with vertebral compression fracture will be included in the study. The patients will be divided into three groups according to the anesthetic method as conventional local anesthesia infiltration (CLIA) method and extrapedicular infiltration anesthesia (EPIAA) and 30 other patients as US guided erector spina group (ESP) for a total of 60 patients. The degree of pain in the intraoperative period will be assessed using a numerical rating scale. Patients with severe pain (NRS> 4) will receive 50 micrograms of fentanyl as an additional analgesic. Sedation levels of the patients will be evaluated with ramsey sedation scale (1-6). Patients with a sedation score of 1 will receive 2 mg of midazolam. During the procedure, pain scores at 0 minutes, 15, 30 and 45 minutes, sedation scores, additional analgesic and sedation amounts administered, and hemodynamic parameters will be recorded. The statistical difference between the groups will be compared
The clinical trial will compare pain perception during dental local anesthesia injections with and without using soft tissue vibration device prior to injection. The primary goal is to test the effectiveness of such devices in pain/discomfort reduction during intraoral local anesthesia injections in various techniques (infiltration and block anesthesia).
Peripheral nerve blocks with use of USG allowed visualisation of the structures and nerves and made the block administrations safe, quick and comfortable. However there are few publications concerning the minimum local anesthetic volume capable of providing blocks. In this study the investigastors aimed to find Minimum Effective Volume Of Local Anesthetic For Ultrasound-Guided İnfraclavicular Approach for Brachial Plexus Blockade in upper limb operations.
Investigators' goal is to determine whether Erector Spinae Plane Block would provide a better analgesia, help mobilization and early discharge or increase satisfaction for patients undergoing Percutaneous Nephrolithotomy(PNL). One of the two groups will receive ESP catheterization after general anesthesia conducted. The other group will receive routine analgesia protocol used for PNL. The total amount of drugs administered, pain scores(NRS) at certain time intervals and at certain events(removal of nephrostomy and pain at mobilization) will be recorded and compared.
Introduction: The risk of systemic toxicity when using bupivacaine is a persistent problem, making its pharmacokinetic study crucial to the safety of regional anesthesia (RA). Little evidence exists regarding the effect of different concentrations of this drug on peak plasma levels. The present study compares two bupivacaine concentrations to establish how the concentration and exchange area affect the peak plasma level of this drug during axillary brachial plexus block. Latency and postoperative analgesia periods were also compared. Methods: 32 patients were randomly assigned to two groups. In the 0.25% group, 10 ml of 0.25% bupivacaine was injected per nerve; in the 0.5% group, 5 ml of 0.5% bupivacaine was injected per nerve. Peripheral blood samples were collected every 15 min during the first hour and every 30 min during the second hour to establish serum level dosage. High-performance liquid chromatography coupled with mass spectrometry was used for the analysis.
Severe pain following shoulder surgery is common and remains a major challenge. The interscalene nerve block is well suited for operations on the shoulder or upper arm, for providing surgical anesthesia as well as prolonged effective postoperative analgesia. Modern ultrasound guided ISB (US-ISB) allows for more accurate, targeted deposition of local anesthetic. The current trend is to lower the volume of local anesthetic for ultrasound-guided interscalene block in order to reduce potential complications such as phrenic nerve paralysis and local anesthetic toxicity. However, at low volumes the analgesic duration of the block could be compromised. Studies to elucidate the best local anesthetic agent, concentration and adjuncts to prolong analgesia at low volumes are needed. Ropivacaine and Bupivacaine are long acting local anesthetics commonly used for peripheral nerve blocks, however, there are no studies comparing their analgesic duration in the setting of low volume interscalene block to date. This study will investigate the analgesic duration of 0.5% Ropivacaine versus 0.5% Bupivacaine with 1:200,000 epinephrine versus 1% Ropivacaine for low volume US-ISB. This study aims to conduct a comparison of the duration of post operative analgesia achieved by these agents, hence allowing the appropriate local anesthetic agent and concentration selection in low-volume techniques.
Anecdotal reports suggest buffering lidocaine with epinephrine just before intraoral injection reduces time of onset, results in a deeper anesthetic effect, without the "sting" with injection from a low pH. Additional data are needed to establish clinical important outcomes such as the peak blood level of lidocaine as compared to the non-buffered drug combination. Clinical pilot studies are proposed as the start of a series of investigations to support or modify the use of the buffered anesthetic for intraoral procedures.
