Filter by:The aim of this work to compare between the efficacy of ultrasound guided TAP block with dexamethasone as an adjuvant versus ultrasound guided TAPB with methyl prednisolone as an adjuvant to local anesthetic for postoperative pain management in lower abdominal hysterectomy procedures.
It is widely accepted that thoracotomy causes severe acute pain. This increases the frequency of postoperative pulmonary complications and postoperative morbidity. Many analgesic methods have been proposed for thoracotomy pain, including thoracic epidural analgesia (TEA), thoracic paravertebral block (TPVB), intercostal nerve blocks (ICSB), erector spinae plane block (ESPB), serratus anterior plane block (SAPB). Among these methods, ultrasound-guided TPVB and ESPB are the most used methods. TPVB has left its place to newer techniques such as ESPB due to its proximity to the pleura and its deeper location. ESPB is more superficial, easy to access, and less likely to have complications. In addition, ESPB application is increasing in patients who underwent thoracotomy and VATS. There is no consensus on the dose of analgesia in these studies. There are studies on volumes between 10 ml and 40 ml in the literature. In this study, it was aimed to compare the volumes of 20 ml and 30 ml containing local anesthetic at the same concentration (0.25% bupivacaine) of ESPB block to be performed with USG in patients who underwent thoracotomy.
On average, more than 130 Americans die every day from opioid overdose. Surgeons provide 37% of all opioid prescriptions in the United states, second only behind pain management physicians. A recent report found that patients who receive a 5-day supply of opioid medication have a 10% chance of using opioids 12 months later. Additionally, studies have shown that many opioid abusers are not the intended recipient, with over half diverting them from friends and family. Rhinoplasty is one of the most common procedures performed by facial plastic surgeons, with over 215,000 performed in the United States in 2017. Patients undergoing nasal surgery have been shown to be at significant risk for persistent and prolonged opioid use after filling an opioid prescription in the perioperative period. Thus, the management of postoperative pain without contributing to the opioid epidemic is a imperative. The first three days following nasal surgery are generally associated with considerable pain, with the highest levels occuring within the initial 24 hours. Published studies have demonstrated the benefit of non-opioid medications following rhinoplasty, such as pregabalin and celecoxib. There has also been growing recognition of the benefits of "pre-emptive analgesia," such as the use of local anesthesia, which not only helps control pain, but in turn decreases the anxiety caused by pain and can prevent patient turning to narcotics to break the cycle. These studies have predominantly focused on the immediate postoperative period, e.g. the first 24 hours. Currently, many surgeons use lidocaine with 1% epinephrine as local anesthesia for rhinoplasty due to its widespread availability, rapid time to onset, and safety profile. Several studies have shown the benefit of Marcaine bupivacaine over lidocaine for pain control and opioid consumption during the first 24 hours after surgery. This is not surprising, as the half-life of lidocaine is approximately 90 minutes in a healthy individual, compared to 160 minutes for Marcaine bupivacaine. However, there are no studies to date that have evaluated the effect that long-acting local anesthesia has on post-operative opioid consumption past the first 24 hours after surgery. Our study aims to compare total postoperative opioid use for patients who received lidocaine as local anesthesia at the time of surgery versus a mixture of lidocaine and Marcaine bupivacaine.
The primary objective is to compare the success of the inferior alveolar nerve block using ultrasound versus a traditional landmarking technique (which historically has an approximate failure rate as high as 33.8%). The secondary objective is to demonstrate that delivering a block under ultrasound guidance does not cause any additional pain to patients, as well as to reconfirm data shown in a previous study that the intra-oral transducer is well-tolerated among patients.
Background: The use of local anesthetics as a supplement to conventional techniques in breast surgery is widely reported in the literature. Currently there is controversy regarding the efficacy of surgery for breast infusion of local anesthetic after surgery. The aim of this study demonstrate the efficacy of administering a local anesthetic into the surgical bed of women operated radical mastectomy for breast cancer for the control of postoperative pain. Material and methods: double-blind randomized clinical trial. The investigators recruited patients who underwent modified radical mastectomy that met inclusion and exclusion criteria. The intervention group were infused with L-bupivacaine 0.50% 2 ml/h for 48 hours, and saline control group at 2 ml/h during surgery and anesthetic technique 48 hours. Local anesthetic and rescue medication was identical in both groups. Statistical analysis: The baseline patient characteristics of the patients were analyzed by Chi square or Student t always meet criteria of normality, otherwise it will use the Mann-Whitney. To determine the effectiveness of treatment as well as pain scale adverse events will be held on chi-square test.
This study will test the hypothesis that sequential injection of 1.5% mepivacaine followed 90 seconds later by 0.5% ropivacaine in ultrasound guided supraclavicular block provides a quicker onset and a longer duration of analgesia than an equi-dose mixture of the two local anesthetics.
