Participants to be enrolled in this study will have been scheduled to have laparoscopic genitourinary surgery and EPAD monitoring as part of their clinical care intraoperatively. Patients scheduled for genitourinary surgery are often at risk for developing nerve injuries due to intraoperative positioning. Somatosensory evoked potential devices (SSEP) are commonly used to detect pending injury to peripheral nerves. The purpose of the present study is to use SSEP monitoring to determine the incidence and potential causes of significant changes in SSEP waveforms and correlate these changes with neurologic status of the brachial plexus after robotic surgery.
This is an open-label, non-comparative phase II clinical trial to assess efficacy and safety of tongue conservation treatment with sequential induction chemotherapy, tongue conservation surgery and postoperative concurrent chemoradiotherapy (CCRT) in patients with advanced oral tongue cancer.
This is a prospective, single-center, cohort study in patients undergoing surgical procedures to collect data using Masimo SedLine EEG device in order to evaluate a newer version of PSI measurement against an older version of PSI measurement.
The Foley catheter is one component in a catheter insertion procedure that could contribute to a catheter associated urinary tract infection (CAUTI). Improvements in the catheter insertion procedure using the ERASE CAUTI Tray system may help to lower these infection rates.
The purpose of this study is to evaluate the effect of pharmacogenetic (PGx) guided treatment when implemented into the pre-operative process for patients undergoing an elective spinal surgical procedure and requiring post-operative acute pain management, as compared to a group of subjects with the same attributes without the guidance of PGx testing for their post-surgery pain management. This study will also evaluate whether PGx testing can reduce narcotic consumption, opioid-related adverse effects, time to mobilization, medical visits and costs.
Cervical incompetence complicates approximately 1 in 500 pregnancies . Those women with cervical incompetence are at risk for second trimester spontaneous abortion and preterm labor. Cervical cerclage reduces these risks but must be performed under general or neuraxial anesthesia. Some anesthesiologists prefer neuraxial anesthesia, as it reduces fetal exposure to medications and avoids the risks associated with loss of maternal airway reflexes under general anesthesia. Spinal anesthesia, in particular, has the added advantage of being technically simple while still providing a rapid, dense sensory block. For cerclage placement, patients require a sensory block from the T10 to S4 dermatome in order to cover sensation from the cervix as well as the vagina and perineum. Patients presenting for cerclage under spinal anesthesia pose a dosing challenge given the physiologic changes associated with pregnancy. As women progress with their pregnancy, they require lower doses of intrathecal local anesthetic to achieve similar block level. Multiple studies have demonstrated that these changes start during the second trimester. Inadequate sensory coverage with a spinal anesthetic typically necessitates conversion to general anesthesia, causing additional time wasted and added risk to the patient and fetus. Anecdotally, this is the reason why some anesthesiologists choose general anesthesia for patients undergoing cerclage over a spinal anesthetic. As there is currently no literature determining the correct dosage for these patients, we propose a dose-response study to determine the ED90 of intrathecal lidocaine for adequate anesthesia for elective cervical cerclage placement.The findings of this study will help determine the minimum dose of intrathecal lidocaine necessary to provide adequate spinal anesthesia for cervical cerclage for 90% of women. This will help decrease the frequency of inadequate anesthesia for cervical cerclage.
Caudal injection of local anesthetic is a neuraxial technique routinely performed on young children for postoperative analgesia after lower abdominal and lower extremity surgical procedures. One of the major limitations of the use of single shot neuraxial injections for this purpose is the limited duration of action of the injected local anesthetic. Adjuvant medications, such as clonidine and epinephrine, have been added to the local anesthetic to prolong the duration of the neuraxial block, with varying results. Dexamethasone is a synthetic glucocorticoid steroid commonly used in the perioperative setting for a multitude of indications, including the prolongation of local anesthetic based analgesia. It has been shown that the administration of dexamethasone either intravenously or via perineural injection can significantly increase the duration of analgesia derived from a local anesthesia based peripheral nerve block. Literature also suggests that the effect of dexamethasone is equivalent whether given intravenously or perineurally. Interest in dexamethasone enhanced caudal analgesia exists and a previous study noted that caudal anesthesia can be prolonged by intravenous dexamethasone. The study was criticized for using a higher dose of dexamethasone (0.5 mg/kg) than is routinely used in the pediatric population outside of airway procedures, which may expose patients to dose related side effects of dexamethasone. A large meta-analysis has suggested that 0.1 mg/kg is effective for analgesic prolongation, but no direct study of low dose intravenous dexamethasone in combination with caudal anesthesia has been performed.
To identify a better method using a combination of routine anesthetic drugs to improve hemodynamic stability during Mayfield head pinning for craniotomy surgery.
The Foley catheter is one component in a catheter insertion procedure that could contribute to a catheter associated urinary tract infection (CAUTI). Improvement in the catheter insertion procedures using the ERASE CAUTI Tray system may help to lower these infection rates.
It has been shown that N-methyl-D-aspartate (NMDA) receptor antagonists (such as ketamine) potentiate analgesic drug's efficacy. Polyamines are allosteric modulators of NMDA receptors. In animal studies, polyamine-free diet has shown antinociceptive properties. This research aims at evaluating analgesic properties of polyamine-low diet after laparoscopic cholecystectomy performed in an ambulatory setting.
