Effective post-surgical pain management is a crucial component of a patient's postoperative course following posterior colporrhaphy. Narcotics are the cornerstone for postoperative analgesia with a frequent re-dosing requirement, a lengthy list of side effects and adverse reaction risks. The colorectal, orthopedic and general surgery literatures have reported on an extended-release bupivacaine liposomal injection, Exparel®, which remarkably reduces acute post-operative pain; however, literature regarding this medication specific to Urogynecology and Gynecology is limited. The investigators propose a prospective, randomized, double blind, trial with 120 subjects recruited from the Walter Reed National Military Medical Center (WRNMMC) Urogynecology Clinic to study postsurgical pain control after posterior repair. There will be two arms in the study; one arm with bupivacaine alone and a second arm with bupivacaine mixed with Exparel®(extended-release, liposomal bupivacaine) injected vaginally in patients undergoing posterior colporrhaphy. Subjects will be randomized to receive either 20 milliliter (mL) of plain bupivacaine or 20mL (10ml+10ml) mixture of bupivacaine plus Exparel®. The primary objective of the trial will be to evaluate the postsurgical vaginal pain using a visual analog pain scale at days 1, 2, 3 post-procedure. All subjects will have acetaminophen, a non-steroidal anti-inflammatory drug and narcotic pain medication available for pain control regardless of assignment, which is the usual postoperative pain control regimen. The investigators hypothesize a 30% difference in post-operative pain measurements between the two groups. Additional objectives of this study are to evaluate total medication usage on days 1, 2 and 3 and any post-operative voiding and defecatory dysfunction, comparing the two groups
Thoracic epidural analgesia (TEA) is the basic method of analgesia in patients undergoing pulmonary lobectomy. TEA is considered to be a safe and thoroughly investigated method of pain relief that rarely causes serious complications. However, blocking the nerves as they emerge from the spinal column (paravertebral block, PVB) may represent an alternative method with some potential benefits. In this study, TEA and PVB will be compared for patients undergoing pulmonary lobectomy by video assisted thoracoscopic surgery. The aim of the study is to test the hypothesis, that PVB is a time-saving procedure compared with TEA on the day of surgery and that PVB is as efficient in postoperative pain reduction as TEA.
The aim of work is to assess and compare the analgesic efficacy of bilateral erector spinae plane block with that of bilateral transversus abdominis plane block after elective cesarean section.
The study aims to determine the tolerability of repeated doses of Maxigesic® IV over an extended period of exposure.
Magnesium sulfate has been shown to be useful in many situations in medicine, such as eclampsia prevention and treatment, pulmonary hypertension, arterial pressure, asthma, cardiac arrhythmias and pheochromocytoma. Recently there has been a growing a big interest in this drug as an useful adjuvant in anesthesia, with analgesic and anesthetic sparing effect, antihyperalgesic property and potentialization of the neuromuscular blocker agent effect. On the other hand there has been a growing concern related to opioid administration, such as hyperalgesia, delayed return of intestinal function and the (still controversial) possibility of facilitating effect on tumor growth and metastases in cancer patients. This project is based on a previous randomized, double blind prospective trial (conducted by one of these authors and not yet published) comparing two groups of patients who received general intravenous total anesthesia with propofol in controlled target infusion. The surgical stress index is obtained by the interaction between the interval between heart beats and the amplitude of the photoplethysmography wave, whose algorithm generates a number related to the hemodynamic result of the increase of the sympathetic tone, which has shown to be the most sensitive resource in detecting the imbalance between the stimulus nociceptive and anti-nociception.
Intense e recurrent nociceptive stimulation, which occurs in the postoperatively, can trigger sensitization of the peripheral and central nociceptive pathway, leading to chronic pain. Patients with rotator cuff injury often present to surgery due to referred moderate to intense long-term pain. During the immediate postoperative period, pain is rare due to the routine administration of a brachial plexus blockade as an adjuvant to improve the quality of postoperative analgesia. However, after the second postoperative day, the effect of the blockade ceases, and the pain becomes high and hard to treat, leading the patient to request administration of more frequent and more potent analgesics. The aim of this project is to assess the postoperative analgesic benefits of a brachial plexus blockcade 2 days before arthroscopic surgical correction of rotator cuff injury by reducing the sensitization of the nociceptive pathway.
ESP block advantages include its simplicity, easy identifiable ultrasonographic landmarks and low risk for serious complications as injection is into tissue plane that is distant from pleura, major blood vessels and discrete nerves. Coupled with the fact that the erector spinae muscle and ESP extend down to the lumbar spine, ESP block was hypothesized to be performed at the level of L4. In a recent case report, ultrasound guided ESP block was successfully performed at L4 transverse process level for postoperative analgesia after total hip arthroplasty. However, confirmation of the efficacy of ESP block in hip replacement surgeries needed more investigation.
Magnesium sulfate has been applied in various situations due to actual or potential benefits related to neuroprotection, treatment of eclampsia/pre-eclampsia, arterial hypertension, adrenergic reflex under laryngoscopy/intubation and, shivering, nausea and vomiting, among others. In anesthesia it has been useful as an analgesic adjuvant; however, the method to calculate the dose of magnesium sulfate in obese population is unclear. The objective of this project is to compare two methods of dose calculation based either on the real weight or corrected ideal weight.
Total knee replacement (TKR) is a commonly performed surgical procedure, and is associated with moderate to severe acute postoperative pain. Poor acute postoperative pain control has been associated with increased morbidity, prolonged recovery, reduced patient satisfaction and chronic post-surgical pain. Multimodal analgesia in the context of enhanced recovery after surgery programs is advocated for conventional total knee replacement. More recently, robotic arm assisted total knee replacement has been introduced. TKR is most commonly performed under spinal anaesthesia or general anaesthesia using inhalational agents or propofol total intravenous anaesthesia (TIVA). It is unclear which is the best anaesthetic technique for postoperative analgesia. There has been no head to head trial comparing these 3 anaesthetic techniques in the context of modern multimodal and enhanced recovery after surgery (ERAS) protocols for conventional and robotic arm assisted TKR. Propofol TIVA may reduce postoperative pain and opioid consumption after surgery, but the overall evidence is still controversial. Whether propofol TIVA provides better analgesia compared to inhalational anaesthesia for TKR is not known. A prospective, randomized controlled trial providing head to head comparisons between general anaesthesia with propofol TIVA, inhalational anaesthesia, and spinal anaesthesia under is indicated. In this study, we plan to perform a randomized controlled trial to compare postoperative analgesia after robotic arm assisted TKR in three commonly used anaesthetic techniques: 1) spinal anaesthesia (SA), 2) general anaesthesia with inhalational anaesthesia (GAS), 3) general anaesthesia with propofol TIVA (TIVA). This clinical trial will be conducted within the framework of modern multimodal analgesic and enhanced recovery after surgery pathways.
