Perioperative Ketamine Use For Post Mastectomy Pain, Alessia Cooney, Jaylyn Thompson, Naomi Watkins-Granville

Rowan-Virtua Research Day

PMPS is defined as chronic neuropathic pain following breast cancer procedures in the ipsilateral arm, chest wall, axilla or shoulder.1-3 Approximately 20 to 50% of post mastectomy patients suffer from Post Mastectomy Pain Syndrome (PMPS).1 With more than 3.8 million breast cancer survivors, due to advances in treatment, there is increased importance in findings ways to better manage the quality of life of breast cancer survivors.1,4 Ketamine induces analgesic effects through its non-competitive antagonism of NDMA receptors.5 Low doses of ketamine infusion (20–30 mg x h−1) have been shown to produce analgesia in neuropathic pain states with benefits lasting up …

Beyond The Raskin Protocol: Ketamine, Lidocaine, And Other Therapies For Refractory Chronic Migraine., Jeffrey J. Mojica, Eric S. Schwenk, Clinton Lauritsen, Stephanie J. Nahas

Department of Anesthesiology Faculty Papers

PURPOSE OF REVIEW: The purpose of this review is to discuss the available evidence and therapeutic considerations for intravenous drug therapy for refractory chronic migraine.

RECENT FINDINGS: In carefully monitored settings, the inpatient administration of intravenous lidocaine and ketamine can be successful in treating refractory chronic migraine. Many patients with refractory chronic migraine have experienced treatment failure with the Raskin protocol. The use of aggressive inpatient infusion therapy consisting of intravenous lidocaine or ketamine, along with other adjunctive medications, has become increasingly common for these patients when all other treatments have failed. There is a clear need for prospective studies …

Ketamine In The Past, Present, And Future: Mechanisms, Metabolites, And Toxicity., Eric S. Schwenk, Basant Pradhan, Rohit Nalamasu, Lucas Stolle, Irving W. Wainer, Michael Cirullo, Alexander Olsen, Joseph V. Pergolizzi, Marc C. Torjman, Eugene R. Viscusi

Department of Anesthesiology Faculty Papers

PURPOSE OF REVIEW: While ketamine's analgesia has mostly been attributed to antagonism of N-methyl-D-aspartate receptors, evidence suggests multiple other pathways are involved in its antidepressant and possibly analgesic activity. These mechanisms and ketamine's role in the nociplastic pain paradigm are discussed. Animal studies demonstrating ketamine's neurotoxicity have unclear human translatability and findings from key rodent and human studies are presented.

RECENT FINDINGS: Ketamine's metabolites, and (2R,6R)-hydroxynorketamine in particular, may play a greater role in its clinical activity than previously believed. The activation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) and the mammalian target of rapamycin by ketamine are mechanisms that are still being …

Pain Control: Opioid Vs. Nonopioid Analgesia During The Immediate Postoperative Period, Shamsie M. Lumpkin Bsn, Srna, Isaac W. Parrish Bsn, Srna, Austin S. Terrell Bsn, Srna, Dwayne S. Accardo Dnp, Aprn, Crna

Doctor of Nursing Practice Projects

Background Opioid analgesia has become the mainstay for acute pain management in the postoperative setting. However, the use of opioid medications comes with significant risks and side effects. Due to increasing numbers of prescriptions to those with chronic pain, opioid medications have become more expensive while becoming less effective due to the buildup of patient tolerance. The idea of opioid-free analgesic techniques has rarely been breached in many hospitals. Emerging research has shown that opioid-sparing approaches have resulted in lower reported pain scores across the board, as well as significant cost reductions to hospitals and insurance agencies. In addition to …

Evidence-Based Best Practice Policy Recommendation For Postoperative Sore Throat, Corey Gambrell

Doctoral Projects

Airway management is a fundamental aspect of patient care when general anesthesia is being administered. Unfortunately, tracheal intubation can lead to the development of postoperative sore throat (POST) in the recovery room. POST is a minor yet preventable consequence of manipulation and injury of the airway mucosa. POST is routinely considered a minor postoperative complication; however, the occurrence of POST can have a negative influence on patient satisfaction as well as their perception of the perioperative experience. The etiology of POST is multifactorial, but evidence indicates that prevention is possible when evidenced-based practices are employed by anesthesia providers. A targeted …

Designing The Ideal Perioperative Pain Management Plan Starts With Multimodal Analgesia., Eric S. Schwenk, Edward R. Mariano

Department of Anesthesiology Faculty Papers

Multimodal analgesia is defined as the use of more than one pharmacological class of analgesic medication targeting different receptors along the pain pathway with the goal of improving analgesia while reducing individual class-related side effects. Evidence today supports the routine use of multimodal analgesia in the perioperative period to eliminate the over-reliance on opioids for pain control and to reduce opioid-related adverse events. A multimodal analgesic protocol should be surgery-specific, functioning more like a checklist than a recipe, with options to tailor to the individual patient. Elements of this protocol may include opioids, non-opioid systemic analgesics like acetaminophen, non-steroidal anti-inflammatory …

Subanesthetic Ketamine For Postoperative Analgesia: An Evidenced-Based Project, Jeremy Vance

Doctoral Projects

Roughly 100 million surgical procedures are performed in the United States (U.S.) each year and more than 80% of these patients experience acute postoperative pain. Pain costs the U.S. an estimated $560 to $635 billion annually and is a significant contributor to national rates of mortality, morbidity, and disability. Despite these findings, patients continue to receive suboptimal postoperative pain relief.

The adjunct administration of subanesthetic ketamine is opioid-sparing and can improve the effectiveness of a multimodal pain management approach. This project used an exploratory descriptive design to examine how an evidence-based presentation impacted the clinical practice of certified registered nurse …

Adverse Drug Effects And Preoperative Medication Factors Related To Perioperative Low-Dose Ketamine Infusions., Eric S. Schwenk, Stephen F. Goldberg, Ronak D. Patel, Jon Zhou, Douglas R. Adams, Jaime L. Baratta, Eugene R. Viscusi, Richard H. Epstein

Department of Anesthesiology Faculty Papers

High-dose opioid administration is associated with significant adverse events. Evidence suggests that low-dose ketamine infusions improve perioperative analgesia over conventional opioid management, but usage is highly variable. Ketamine's adverse drug effects (ADEs) are well known, but their prevalence during low-dose infusions in a clinical setting and how often they lead to infusion discontinuation are unknown. The purposes of this study were 3-fold: (1) to identify patient factors associated with initiation of ketamine infusions during spine surgery, (2) to identify specific spine procedures in which ketamine has been used most frequently, and (3) to identify ADEs associated with postoperative ketamine infusions …

Effect Of Low-Dose Ketamine Versus Fentanyl On Attenuating The Haemodynamic Response To Laryngoscopy And Endotracheal Intubation In Patients Undergoing General Anaesthesia At The Aga Khan University Hospital, Nairobi, Angela Ongewe

Theses & Dissertations

Background: The use of drugs to attenuate the haemodynamic response to laryngoscopy and endotracheal intubation is the standard of care during elective surgery. Current evidence is conflicting concerning the best agent and optimal dose for this purpose. In the majority of cases, Fentanyl is widely utilized to attenuate haemodynamic responses. Ketamine, an established available drug, has been scarcely studied in this regard at low doses and against varying doses of other common agents.

Objective: The primary objective was to compare the overall occurrence of hypertension and tachycardia immediately pre-intubation (post-induction) until 10 minutes post intubation between the study group receiving …

A Randomized Control Trial To Assess The Effect Of Aketamineinfusion On Tourniquet Hypertension During General Anaesthesia In Patients Undergoing Upper And Lower Limb Surgery, Joyce Atieno Ongaya

Theses & Dissertations

Background: Tourniquet hypertension arising from tourniquet inflation remains of primary concern to the anaesthetist. One drug commonly used to manage tourniquet hypertension is ketamine. Several studies show that ketamine attenuated the blood pressure rise associated with tourniquet inflation. None of the studies carried out examined the effect of ketamine on tourniquet hypertension for a period of more than one hour or an infusion of the same.

Objective: To compare the effect of an intravenous infusion of ketamine, versus placebo on tourniquet induced hypertension in patients undergoing upper and lower limb surgery under general anaesthesia

Study design: Single blinded Randomized …
