Filter by: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.
To adequately assess postoperative pain in the coronary artery bypass surgical population a multicentered retrospective chart review was carried out; the study utilized a nonexperimental comparative descriptive study design. The retrospective review was conducted over a six-month time frame, consisting of June 2017 through November 2017, at two hospitals within the same organization. The data collection process began in late December of 2017 and January of 2018. The assessment of postop pain was performed by using a standard 11-point numeric pain rating scale on post extubation day one and the day of discharge.
Patients were randomly allocated into Two equal study groups each contain (40) patients : Patients in Group A received supraclavicular block using 25mL of 0. 5% bupivacaine and 1 mL normal saline and patients in Group B received 25 mL 0. 5% bupivacaine and 1 mL neostigmine (0.5 mg). The investigators found that neostigmine when used as an adjuvant to bupivacaine in ultrasound guided supraclavicular brachial plexus block has advantage over bupivacaine alone especially in the quality of sensory block and provide safe and effective post-operative analgesia in patients undergoing forearm surgeries
The purpose of this phase 3 study is to evaluate the efficacy and safety of an analgesic drug candidate, VVZ-149 Injections for treating post-operative pain following abdominoplasty.
The purpose of this phase 2 study is to evaluate the efficacy and safety of an analgesic drug candidate, VVZ-149 Injections for treating post-operative pain following bunionectomy.
Total knee arthroplasty is a common and effective surgical procedure for patients with end‐stage knee osteoarthritis, and wound pain is still a problem for many of the patients.
This study aims to 1) observe the course of pain, 2) utilization of opioid pain medication, and 3) possible effect of a behavioral intervention delivered via an automated mobile phone messaging robot in patients undergoing surgical treatment of a traumatic orthopaedic injury.
