Filter by:In this retrospective study, postoperative pain score, epidural patient controlled analgesia (Epi-PCA) related complications, the risk factors for requirement of rescue analgesics and antiemetics will be evaluated in young and elderly patients, respectively, using fentanyl and ropivacaine-based Epi-PCA during postoperative 48 hours after various surgeries.
This research study is testing whether the local anesthetic lidocaine is as effective as ropivacaine for post-operative pain control in continuous thoracic paravertebral nerve blocks. Ropivacaine and Lidocaine are FDA-approved drugs that has been successfully used in this hospital for post-operative pain control for the past few years, thus has become the standard drugs used for this nerve block. Lidocaine has numerous potential advantages over ropivacaine, such as faster onset of action, better safety profile and greater anti-inflammatory action. Catheters placed near both sides of a patient's spine for postoperative pain control are called thoracic paravertebral nerve blocks and are a part of routine care. Through those catheters, a "numbing" medication, or local anesthetic, to block the transmission of pain from the surgical incision to the spinal cord, thus reducing pain. The research part of the study is whether subjects will receive either the local anesthetic lidocaine or ropivacaine. The goal of this study is to determine whether the lidocaine controls pain better and facilitates a faster recovery after abdominal surgery than ropivacaine. In this research study, the investigators will compare patient-reported pain scores, any additional pain medication requirements for adequate pain control, time it takes for bowel function to return to normal following surgery, as well as the incidence of any side effects, such as numbness and weakness, subjects may experience between those receiving lidocaine versus those receiving ropivacaine. The investigators will screen 100 patients and enroll 60 subjects into this study.
Breast augmentation surgery can cause important postoperative pain, especially when bilateral subpectoral implants are used. The investigators hypothesized that a technique of regional analgesia, the pectoral nerve block type I (or "PECS I block") would reduce pain within the first twenty-four hours and, in turn, morphine consumption and associated side effects. This is a randomized, controlled, double-blind study which compares intra and postoperative analgesia with or without PECS I block in breast surgery.
ASA I-II 3-12 years old children participated to this study. All Participants will divide into the three groups. In Groups I, 2,5 mg/kg propofol and 0,5 mg/kg ketamine will apply at anaesthesia induction. General anaesthesia will be performed with 5/1 ratio of ketamine-propofol mixture with %67 of Mcfarlan dose regiment. In Groups II, 2,75 mg/kg propofol and 0,41 mg/kg ketamine will apply at anaesthesia induction. General anaesthesia will be performed with 6,7/1 ratio of ketamine-propofol mixture with %80 of Mcfarlan dose regiment. In Groups III, 3 mg/kg propofol and 0,3 mg/kg ketamine will apply at anaesthesia induction. General anaesthesia will be performed with 10/1 ratio of ketamine-propofol mixture with %90 of Mcfarlan dose regiment. After than surgical operation recovery time, PAED scores, FLACC scores, Staying time in PACU will be recorded. These data will be evaluated with statistically.
The purpose of this phase 2 study is to evaluate the efficacy and safety of an analgesic drug candidate, VVZ-149 Injections. The study is designed as randomized, double-blind, parallel, and placebo-controlled study.
Objective: The objective of the study was to assess the usefulness of ThPVB in postoperative pain management after open renal resection surgery. Design, setting, participants: It was a prospective, randomised, open label study held in a university hospital between 08.2013-12.2014. 58 Patients enrolled in the study were scheduled for elective open renal surgery (open nephrectomy or open nephron-sparing surgery) and randomised into two groups - group PVB (n=27) and group GEN (n=31). Interventions: PVB group received preoperative ThPVB with 0,5% bupivacaine followed by general anaesthesia. GEN group received standard general anaesthesia. Both groups were treated postoperatively with oxycodone IV PCA (patient controlled analgesia) combined with non-opioid analgesics as rescue drugs. The investigators recorded pain severity in VAS, oxycodone requirement in time points, total oxycodone requirement, and sedation levels throughout the first 48h. The investigators measured opioid related adverse events 24 and 48 h postoperatively and patients satisfaction 48h postoperatively.
Background and Objectives: Postoperative analgesia and early recovery are relevant for hospital discharge after hemorrhoidectomy. This study investigated the postoperative analgesic effect with local infiltration compared with spinal block. Methods: This randomized study included 40 patients aged 18 to 60 years old. Local group (LG) received local infiltration under general anaesthesia; spinal group (SG) received a subarachnoid block. LG received general anaesthesia with propofol, atracurium and propofol infusion as well as a local infiltration of 20 ml 0.75% ropivacaine. SG received 2 ml of 0.5% hyperbaric bupivacaine. Analgesic supplementation was with 50µg of fentanyl for LG and 1% lidocaine for SG. There were assessed: postoperative pain intensity, sphincter relaxation, motor blockade of lower limbs, time to discharge, analgesic dose over 1 week and adverse effects.
The purpose of this study is to determine if the infusion of the local anesthetic ropivacaine (a numbing medicine) and the non-steroidal anti-inflammatory drug ketorolac (a pain killer similar to ibuprofen) through a catheter placed along the cesarean delivery incision, will reduce the pain experienced after cesarean section and need for narcotic pain medicine.
The aim is to investigate the effect of perineural administration of a series of different volumes of local anaesthesia (ropivacaine 0.2%) on nerve block duration and the variability of the duration in the common peroneal nerve and the sciatic nerve in healthy volunteers. The hypothesis is that nerve block duration is correlated to local anaesthetic volume, but only to a certain degree. After a sufficient volume a 'saturation level' will be reached, and nerve block duration will not increase further.
This is a randomised controlled trial which will compare the Quadratus Lumborum (QL) Block with the Transversus Abdominis Plane (TAP) Block in terms of analgesic efficacy, ease of performance and safety when administered postoperatively in patients who undergo laparoscopic nephrectomy. To fulfill this purpose, three groups of patients each with 32 patients, will be formed. Patients in the Transversus Abdominis Plane (TAP) group and Quadratus Lumborum (QL) group will each receive the respective blocks with 0.4 ml/kg of 0.25% Bupivacaine, after completion of surgery. The third (Control group) will not receive any blocks. After shifting patients to recovery all three groups will be put into intravenous patient controlled analgesia (PCA) Morphine as rescue analgesic regimen as per a set protocol. Morphine consumption over the first postoperative 24 hours, ease of performance of individual blocks and associated adverse events, adverse events associated with opioid use, patient recovery and satisfaction will be noted.
