The study is a prospective, randomised, controlled double-blind clinical trial. The primary aim was to evaluate the efficacy of caudal block and ilioinguinal-iliohypogastric nerve block with PI and PVI in pediatric inguinal hernia operations under general anesthesia. The secondary aim is to evaluate postoperative analgesic agent consumption and to evaluate the correlation of PI and PVI values with hemodynamic parameters. Pediatric patients between the ages of 2-8 years who are planned to undergo elective inguinal hernia operation will be included in the study. After the patients scheduled for inguinal hernia surgery are admitted to the operating room, routine monitoring will be performed as performed. In addition to routine monitoring, a Radical-97TM Pulse CO-OximeterTM (Masimo Corp, Irvine, CA, USA) probe will be attached to the toe to monitor PI and PVI. Patients will be given anaesthetic drugs as routinely administered. After LMA by randomisation by closed envelope method, caudal or ilioinguinal-iliohypogastric nerve block will be performed by an experienced anaesthetist as the investigators routinely perform in patients other than the control group.. PI, PVI, pulse, saturation, noninvasive arterial pressure values will be recorded before induction, after induction, after LMA, before applied block, after applied block (after surgical incision) at 0, 5, 10, 15, 20, 25 and 30 minutes and at the end of anaesthesia. All patients will be given paracetamol 10mg/kg iv, which is a routine intravenous (iv) analgesic, at the end of surgery. In case of perioperative complications, the complications will be recorded. Flacc pain scale (Face, Legs, Activity, Cry, Consolability) will be applied at 0, 2, 6 hours postoperatively. Postoperative analgesic use and discharge time will be recorded. Flacc pain scale will be performed by an anaesthetist blinded to the study.
Postoperative pain after laparoscopic hepatectomy is composed of multiple factors, and the peak pain of postoperative pain mainly occurs within the first 24 hours, so it is particularly important to find an appropriate analgesic method. Transversus abdominis plane block (TAPB) and Rectus sheath blocks (RSB) are widely used in abdominal surgery, but too deep a needle tip during RSB may puncture abdominal organs. TAPB and RSB can only provide somatic analgesia, but lack visceral analgesia. Recently, Erector spinae plane block (ESPB) has been used in some studies for analgesia after abdominal surgery. The purpose of this study is to compare the analgesic effect and postoperative recovery effect of erector spinae plane block and transverse abdominis plane block combined with rectus sheath block in patients undergoing laparoscopic hepatectomy. Therefore, this study has important clinical implications.
Tests such as the pin-prick test, cold application or the Bromage scale are currently used to measure the success of nerve blocks and are considered subjective assessments as they require verbal consent from the patient. Near Infrared Spectroscopy (NIRS) measures the differential absorption and reflection of near infrared light transmitted by human tissues, providing a tissue-oxygen saturation index. Modern NIRS-based instruments use multiple detectors to filter spectroscopy data from skin structures to detect subcutaneous tissue oxygenation. Successful regional anesthesia results in decreased sympathetic activity within the distribution of blocked nerves. Regional oxygen saturation (rSO2) has been shown to increase in innervated areas after sympathetic block.
The more effective use of ultrasound in regional anaesthesia techniques has made different block applications possible. Lumbar plexus block is also used for post-operative analgesia and surgical anaesthesia. Currently, in-plane ultrasound-guided LPB is widely used in short-axis imaging and Shamrock imaging.
Comparison of post-operative pain after total shoulder surgery. The Principle Investigator will be comparing Exparel single shot block to Interscalene catheter
Postoperative pain score, Faces, Legs, Activity, Cry, Consolability (FLACC) is the primary outcome. The secondary outcomes are the first-time requested analgesia, the number of children required analgesia, the total amount of analgesic requirements during first the 24 hours.
The Aim of This Study is to Determine the Minimum Effective Volume of Local Anesthetic (Ropivacaine 0.5%) Required to Produce an Effective Ultrasound-guided Supra-anterior Superior Iliac Spine Fascia Iliaca Compartment Block（SASIS-FICB） for Surgical Anesthesia in 90% of Patients Scheduled for Elective Surgery of One Lower Limbs.
The situation of demand for surgical conditions is quite high when lymph node resection involved in the surgery type, especially abdominal aortic lymph node dissection, and commonly, the surgeons complained about the interference from the intestine which pushed the investigators to increase the level of neuromuscular blockade close to deep NMB. To avoid the application of deep NMB and promote good surgical conditions for laparoscopic gynecological surgery with lymph nodes resection, the investigators explored other preoperative ways to cooperate with surgeons more harmoniously. It's well known that epidural anesthesia and epidural anesthesia combined with spinal anesthesia have the effect of muscle relaxation which has been applied in clinical practice widely. One study indicated that the Transverse Abdominal Plane (TAP) block could change muscle thickness and achieve the effect of muscle relaxation. It leads investigators to a hypothesis that the sheath of rectus abdominis block combined with transverse abdominal plane block may suppress the signal transmission of abdominal nerve, and may be beneficial to improve surgical conditions.
LIA is the mainstay of postoperative analgesia in patients having knee arthroplasty. The combination of ACB-iPACK blocks has also been proposed as an effective analgesic modality for total knee arthroplasty. However, whether combining these two modalities yields any important incremental analgesic benefit remains unclear. The investigators hypothesized that the addition of ACB and iPACK blocks to LIA will yield clinically important analgesic benefits compared to LIA alone in patients having total knee arthroplasty.
