Filter by:This prospective, randomized study, control study aims to compare the analgesic effect, opioids consumption, quality of recovery, length of hospital stay and et al. between unilateral continuous quadratus lumborum block (QLB) and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing hepatectomy with right J-shape subcostal incision.
The aim of this study is to explore whether the use of ultrasound guided phrenic nerve block can reduce the postoperative pain in the shoulder after liver resection. The intervention is directed postoperative to the patients experiencing novel right sided shoulder pain.
The purpose of this study is to compare lumbar plexus block to fascia iliac block done in adult patients who have undergone hip arthroscopy surgery. Visual analogue scores, opioid consumption, and quality of recovery 48 hours post operatively will be used for comparison.
This prospective, randomized study,control study aims to compare the analgesic effect,opioids consumption,quality of recovery,length of hospital stay and incidence of chronic pain,et al. between single-injection QLB(quadratus lumborum block)+ intravenous patient-controlled analgesia (IPCA) and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing laparoscopic renal surgeries.
This prospective, randomized study,control study aims to compare the analgesic effect,opioids consumption,quality of recovery,length of hospital stay and incidence of chronic pain,et al. single-injection TPVB +continuous(pulsatile infusion) TPVB and intravenous patient-controlled analgesia (IPCA) alone in patients undergoing hepatectomy with right J-shape subcostal incision.
This study compares the long-axis and short-axis technique of continues adductor canal block for total knee replacement surgery. Half participants will receive long-axis catheterization, while the other half will receive short-axis catheterization.
In this study, the investigators will compare the intraoperative opioid consumption for patients undergoing breast cancer surgery. The patients will be divided in two groups, the first one will receive a pectoral nerve block right after induction of anesthesia and the second one, the control group, will not receive the pectoral block. Our hypothesis is that the pectoral nerve block reduces the opioid consumption during the surgery.
Obturator nerve block is an effective method to prevent adductor muscles contraction during transurethral resection of bladder tumour localized on the lateral wall. Due to prior spinal anaesthesia the patient does not feel uncomfortable during the blockade and the interadductor approach gives the possibility to perform it in the lithotomy position. The aim of the study was to evaluate the safety and effectiveness of ultrasound-guided obturator nerve identification and blockade for TURBT.
Ultrasound-guided regional anesthesia is increasingly being used in the modern surgical environment to provide specific intraoperative anesthesia and postoperative analgesia. Infiltration of local anesthesics around peripheral nerves firs blocks sympathetic, then sensory, then motor nerve function. Sympathectomy-induced vasodilation following brachial plexus block results in increased skin temperature and arterial flow within minutes. Although it has not been shown to reliably increase diameter or cross-sectional area of distal arteries, brachial plexus block does change the pattern and quantity of blood flow to the hand. Given that the magnitude of change of flow cannot be attributed to vessel radius, the investigators suspect that the more laminar fluid dynamics are due to vascular tone. The investigators study aims to quantify alterations in physiology and peripheral vasodilator response. The investigators anticipate that axially block will significantly improve regional blood flow.
Can the association of dexamethasone to the local anaesthetic in a single-shot femoral and sciatic nerve block improve analgesia postoperatively in patients submitted to total knee arthroplasty? Primary aim: Evaluate the efficacy of the association of dexamethasone to the local anaesthetic in a SSFNB and SSSNB in reducing pain scores, assessed by VAS. Outcome measures: Mean pain scores in both groups. Secondary aims: Evaluate opioid consumption in the postoperative period (8- 12h, 24h, 48h) and assess incidence of side effects and complications (numbness, paraesthesias, weakness, site infection, haematoma and falls).
