Epidural and Intravenous Patient-Controlled Analgesia Following Lumbar Spinal Fusion Surgery

Postoperative analgesia following spine surgery is difficult to manage. Current treatment modalities rely heavily on opioid analgesics with all of the inherent limitations and side effects. While current best practice focuses on a 'multimodal approach' (i.e. using multiple different drugs and techniques to control pain after surgery), there is no consensus regarding which components of this multimodal therapy provide optimal analgesia. This prospective randomized study will enroll patients undergoing elective Lumbar Spinal Fusion Surgery at Zale Lipshy University Hospital. The primary objective is to determine the comparative efficacy of epidural analgesia, as compared with intravenous (IV) patient-controlled analgesia (PCA), on post-operative analgesia.

Interscalene Bupivacaine With Either Liposomal Bupivacaine or Continuous Peripheral Nerve Block for Shoulder Arthroscopy

This investigation will be a prospective, randomized trial. The study population will consist of adult patients scheduled to undergo major shoulder arthroscopy procedures with anesthesiology at the Ambulatory Services Center (Outpatient Surgery Center). Forty-six subjects will be enrolled in this study and will be randomized into one of two arms: 1) Single-injection bupivacaine HCl plus a subsequent bupivacaine CISB, 2) Single-injection bupivacaine HCl plus liposomal bupivacaine included in the same injection. These procedures will take place, using an ultrasound-guided method, approximately one hour prior to surgical procedure. Subjects will be followed for seven days to assess pain control by the Modified Brief Pain Inventory (MBPI) survey and outcome factors related to study and procedure using the American Shoulder and Elbow Surgeon Shoulder Score (ASES Shoulder Score).

A Study to Compare the Long-term Outcomes After Two Different Anaesthetics (TREX)

There is considerable evidence that most general anaesthetics modulate brain development in animal studies. The impact is greater with longer durations of exposure and in younger animals. There is great controversy over whether or not these animal data are relevant to human clinical scenarios. The changes seen in preclinical studies are greatest with GABA agonists and NMDA antagonists such as volatile anaesthetics (eg sevoflurane), propofol, midazolam, ketamine, and nitrous oxide. There is less evidence for an effect with opioid (such as remifentanil) or with alpha 2 agonists (such as dexmedetomidine). Some, but not all, human cohort studies show an association between exposure to anaesthesia in infancy or early childhood and later changes in cognitive tests, school performance or risk of developing neurodevelopmental disorders. The evidence is weak due to possible confounding. A recent well designed cohort study (the PANDA study) comparing young children that had hernia repair to their siblings found no evidence for a difference in a range of detailed neuropsychological tests. In that study most children were exposed to up to two hours of anaesthesia. The only trial (the GAS trial) has compared children having hernia repair under regional or general anesthesia and has found no evidence for a difference in neurodevelopment when tested at two years of age. The GAS and PANDA studies confirm the animal data that short exposure is unlikely to cause any neurodevelopmental impact. The impact of longer exposures is still unknown. In humans the strongest evidence for an association between surgery and poor neurodevelopmental outcome is in infants having major surgery. However, this is also the group where confounding is most likely. The aim of our study is to see if a new combination of anaesthetic drugs results in a better long-term developmental outcome than the current standard of care for children having anaesthesia expected to last 2 hours or longer. Children will be randomised to receive either a low dose sevoflurane/remifentanil/dexmedetomidine or standard dose sevoflurane anaesthetic. They will receive a neurodevelopmental assessment at 3 years of age to assess global cognitive function.

ESP vs QL for Total Abdominal Hysterectomy

Patients undergoing open total abdominal hysterectomy (n=82) at Parkland Memorial Hospital will be randomized into one of two groups to receive either ultrasound-guided bilateral ESP block with liposomal bupivacaine (Group 1) or ultrasound-guided bilateral QL block with liposomal bupivacaine (Group 2) for postoperative pain management. The remaining aspect of perioperative care, including the general anesthetic technique and postoperative care will be standardized and will be similar for all patients. The duration of the involvement in the study will be until 72 hours postoperatively. Anesthesia providers will identify potential subjects during their Pre-Anesthesia Evaluation Clinic visit and/or Day Surgery Unit pre-anesthetic assessment. There will be no incentive or payment to the patients. Patients in Group 1 will receive ultrasound-guided bilateral ESP block in the preoperative holding area prior to surgery. Patients in Group 2 will receive ultrasound-guided QL block in the preoperative holding area prior to surgery. All patients will have general anesthesia per previously established Parkland Enhanced Recovery After Surgery (ERAS) protocols. Postoperatively, patients in both Groups will receive acetaminophen 1000 mg orally every 8 hours, meloxicam 15 mg orally every 24 hours, and immediate-release oxycodone 5 - 10mg orally every 4 hours as needed for breakthrough pain. The postoperative analgesia will be documented using the Numeric Rating Scale (0-10 scale where 0=no pain and 10=worst pain). In addition, total opioid dose over the 72-hours study period will be documented. Postoperative nausea will be measured using a categorical scoring system (none=0, mild=1, moderate=2, severe=3) and episodes of vomiting will be documented. Rescue anti-emetics will be given to any patient who complains of nausea and/or vomiting. All variables will be assessed at 4, 6, 12, 24, 48, and 72 hours, postoperatively by an investigator blinded to group allocation.
