In this study, the effect of nerve blockade and radiofrequency treatment applied to the nerve on pain in chronic migraine patients will be investigated. Occipital nerve blockade group (control group): Depending on the location of the pain, blockade will be applied unilaterally or bilaterally with 5 cc of 2% prilocaine for each sıde. Pulse Radiofrequency application to the greater occipital nerve will be applicated after radiofrequency cannula placed near the greater occipital nerve location with 42 degree, for 240 seconds.
We aimed to investigate the effectiveness of the pericapsular nerve group (PENG) block applied with preoperative ultrasonography (USG) in patients who were operated on under spinal anesthesia due to hip fracture and whether it influences spinal anesthesia success. The files of 100 patients were reviewed observationally, and 60 patients were included in the study. The patients were divided into two groups: Group P (n = 30) comprising patients who underwent PENG block under USG guidance before the start of surgery and the control group (Group C; n = 30) of patients in whom tramadol infusion was started. From the files of the patients, the transition from the bed to the operating table, lateral decubitus position, skin incision, postoperative exit, postoperative 2nd, 4th, 12th, and 24th hour numeric rating scale (NRS) values, spinal anesthesia duration and number of attempts, and perioperative total tramadol consumption were recorded. During the transfer from the patient bed to the operating table and during the lateral decubitus position, postoperative exit and postoperative 2nd, 4th, 8th, 12th, and 24th hour NRS values were found to be significantly lower in Group P. In addition, lower spinal anesthesia time, lower number of spinal anesthesia attempts, and lower perioperative total tramadol consumption were detected in Group P. We found that PENG block applied preoperatively to patients with spinal anesthesia decreased the perioperative pain score, increased the success of spinal anesthesia by facilitating positioning for spinal anesthesia, and decreased the need for postoperative opioids.
Upper abdominal incisions, such as the oblique subcostal laparotomy, can cause severe pain and can lead to significant respiratory impairment. Erector spinae plane (ESP) block is the deposition of local anaesthetic (LA) in the interfascial plane at the paraspinal region. It provides effective visceral and somatic analgesia. External oblique intercostal plane (EOIP) block is a newly described block at which local anaesthetic (LA) is deposited in the interfascial plane deep to external oblique muscle at the sixth intercostal space. It provides blockade of the thoracoabdominal nerves at the level of T6 to T10. In this study, the investigators compare between ultrasound (US) guided external oblique intercostal plane block and erector spinae plane block, in providing postoperative analgesia for upper abdominal surgeries
Customized bone blocks need CBCT and digital software to design the block needed to rehabilitate. Some advantages are reduced surgical time and better adaptation of the graft, leading to less complications. Objectives: The primary aim of this study is to determine the bone regeneration capacity through a histological study and the bone volumetric changes of allograft bone blocks in the posterior site of the mandible. The secondary outcome will be to assess the survival and success rate of dental implants placed in the allograft regenerated area. Materials and Methods: After studying the CBCT to regenerate the posterior sites of the mandible, the investigators will design CAD/CAM freeze- dried bone allograft to fit exactly on the defect morphology that the patients present. A full thickness flap will be released to have a correct access of the defects. The sterile blocks have to fit perfectly on the defect and fixed by screws. Covered with resorbable membranes fixed with pines and suture. 4 months later, 2nd CBCTwill be performed. During the implant surgery, a bone trephine will be removed and sent into a Laboratory to make a histological study of the bone block for histomorphometry. After 3 months, second-stage surgery and healing caps will be placed if needed. Impressions will be taken 2 weeks after to perform the final crowns.
ESP is the deepest back muscle originating from the transverse processes of the vertebrae. Blocks applied to this region are effective for a longer time and in the broader area than those applied to superficial muscles. Recently, pulsed radiofrequency treatments have also been performed in myofascial pain, and successful results have been obtained. The investigators aim to investigate whether there is a difference between these two applications in terms of treatment efficacy.
This study will consist of patients 18 years and older who are undergoing elective hip replacement with planned same day discharge. The patients will be randomized to receive a PENG+LFC or QL block prior to undergoing the surgery to help with postoperative pain control. The primary goal will be assessing postoperative opioid use during the first 72 hours after surgery. Secondary outcomes will include postoperative pain scores from, 0-72 hours. Additional outcomes consist of time to first ambulation, functional and mobility outcomes, PACU duration, patient satisfaction and opioid related side effects.
Central neuraxial and regional anesthesia and analgesia techniques significantly reduce perioperative morbidity and mortality in the knee and below-knee surgeries.Nerve blocks appear to have better analgesic efficacy compared to placebo or patient-controlled analgesia (PCA). In addition, opioid-related side effects such as postoperative nausea, vomiting, pruritus, sedation, and respiratory depression are less. Therefore, interest in regional blocks such as femoral, sciatic, adductor, combined femoral, and sciatic is increasing. The knee joint is innervated by various nerves (genicular nerves) from the femoral, obturator, and sciatic nerves, and a comprehensive but simple technique is needed for postoperative analgesia. Complete and comprehensive postoperative analgesia was possible with this block, a simple single injection technique. The aim of our study is to evaluate the intraoperative analgesia efficacy of femoral, adductor canal block, and 4in1 block in patients who will undergo knee surgery.
In recent years, the use of regional anesthesia techniques as part of multimodal analgesia strategies to maximize pain control in patients has reduced opioid requirements and promoted early mobility and rehabilitation in the perioperative period. Regional anesthesia has benefits, mainly peripheral nerve blocks (PNB), muscle relaxation, and postoperative analgesia, thus allowing for control of postoperative pain and early discharge from the hospital. In addition, using PNB techniques provides: Hemodynamic stability. Reduced need for a post-anesthetic care unit (PACU). Reduced unplanned hospitalization for pain control. Less airway management. Reduced incidence of opioid-related adverse events. Greater patient satisfaction The main feature of rebound pain is that it is severe pain, within 8-24 hours after PNB. It usually remains severe for 2-6 hours, but the subsequent pain trajectory is consistent with the recovery process expected at surgical intervention. Therefore, rebound pain is temporary and different from persistent post-surgical pain (PPSP). Rebound pain often occurs at night. However, this is probably related to the 8 to 12-hour duration of most single-injection PNBs and the completion of most elective surgeries during daylight hours.
