Brief Review: Does Red Hair Phenotype Affect Propofol Pharmacokinetics Or Pharmacodynamics?, James Espinosa, Frank Wheeler, Robin Lahr, Sergey Medlenov, Alan Lucerna

Rowan-Virtua Research Day

Background: A persistent belief within Emergency Medicine and perioperative culture suggests that individuals with red hair require altered anesthetic dosing. While early studies demonstrated increased requirements for certain volatile anesthetics in red-haired individuals, this association is frequently generalized to propofol without clear supporting evidence.

Objective: To review current literature regarding the relationship between red hair phenotype (and MC1R variants) and propofol pharmacokinetics (PK) and pharmacodynamics (PD).

Methods: A focused narrative review of controlled human studies and relevant clinical outcome data evaluating propofol PK and PD in red-haired individuals.

Results: Evidence supporting altered anesthetic requirement in red-haired individuals primarily derives from …

Setting Up An Ambulatory Gi Endoscopy Suite In The Usa-Anesthesia And Sedation Challenges, Basavana Goudra

Department of Anesthesiology Faculty Papers

Gastrointestinal endoscopy units, both freestanding and associated with ambulatory surgical centers, are on the increase, and the trend is likely to continue. The concept is relatively new, and there are insufficient guidelines and a general dearth of information for prospective planners and physicians. Debate continues in areas such as the selection of patients, appropriateness of procedures, and access to tertiary care. Leaders often scramble to address both critical and non-critical issues, often after the center has opened to the public. They often encounter issues which were not anticipated. In this review, we have provided comprehensive and concise information on the …

Reversal Of Propofol-Induced Depression Of The Hypoxic Ventilatory Response By Bk-Channel Blocker Ena-001: A Randomized Controlled Trial, Simone Jansen, Maarten Van Lemmen, Erik Olofsen, Laurence Moss, Joseph Pergolizzi, Thomas Miller, Robert Colucci, Monique Van Velzen, Philip Kremer, Albert Dahan, Rutger Van Der Schrier, Marieke Niesters

Department of Medicine Faculty Papers

BACKGROUND: The use of anesthetics may result in depression of the hypoxic ventilatory response. Since there are no receptor-specific antagonists for most anesthetics, there is the need for agnostic respiratory stimulants that increase respiratory drive irrespective of its cause. The authors tested whether ENA-001, an agnostic respiratory stimulant that blocks carotid body BK-channels, could restore the hypoxic ventilatory response during propofol infusion. They hypothesize that ENA-001 is able to fully restore the hypoxic ventilatory response.

METHODS: In this randomized, double-blind crossover trial, 14 male and female healthy volunteers were randomized to receive placebo and low- and high-dose ENA-001 on three …

The Effect Of Anesthetic Drugs During Craniotomy On Patient Outcomes, Thomas Vander Woude, Timothy Nold, Katherine Nowak, Donald Penning

Medical Student Research Symposium

Glioblastoma remains an aggressive, highly malignant brain cancer with poor prognosis despite treatment options including surgery, radiotherapy, and chemotherapy. The objective of this retrospective chart review study was to evaluate if there is a correlation between the type and dose of anesthetic drugs administered during craniotomy surgery for glioblastoma and the time to first postoperative tumor progression and mortality. Based on preliminary data in mice, it was hypothesized that the use of propofol during surgery is associated with slower tumor progression and lower mortality, when compared with other anesthetic drugs. In the observed time frame, 133 patients were diagnosed with …

Dexmedetomidine Vs. Propofol In Postoperative Delirium Prevention, Jaclyn Burnett Rn, Srna, Montana Betts Rn, Srna, Christhian De Ochoa Rn, Srna, Maciej Chec Rn, Srna, Dwayne Accardo Dnp, Crna, Aprn

Doctor of Nursing Practice Projects

Purpose/Background Postoperative delirium (POD) is an acute neurological condition affecting large numbers of surgical patients in various practice settings. Patients suffering from this condition face postoperative complications, increased lengths of stay, and tremendous financial burden. Understanding the contributing factors for POD, and how adjustments in intraoperative agents can prevent or reduce the incidence, is a crucial aspect of anesthesia practice. This scoping review will examine associations between POD and the intraoperative use of propofol versus dexmedetomidine with general anesthesia.

Methods Studies in this review were limited to peer-reviewed literature, published in medical and nursing journals within the last five years. …

A Randomized Controlled Trial Comparing The Proportion Of Hypoxia In Sedated Adults Undergoing Upper Gastrointestinal Endoscopy Using Target Controlled Infusion Of Propofol Versus Intermittent Boluses., Catherine Ndosi

Master of Medicine in Anaesthesiology

Background: A wide variety of sedation techniques are employed to facilitate various invasive diagnostic and therapeutic procedures. Increasingly, propofol is emerging as the preferred sedative agent. Traditionally, it has been administered as intermittent boluses to achieve deep sedation to facilitate gastrointestinal endoscopy. Propofol target controlled infusion can be employed to provide suitably conducive conditions for this purpose. Objective: The primary objective sought to compare the proportion of hypoxia between the study group receiving intermittent boluses of propofol at 0.25mg/kg as needed, and the other receiving target-controlled infusion of propofol at 2.5mcg/ml during upper gastrointestinal endoscopy. The secondary objectives were to …

Decreasing Cost In The Gi Endoscopy Suite By Utilizing Best Sedation Practices, Casey Brianne Mancini

Doctoral Projects

Colorectal cancer is a leading cause of cancer death in the United States (Mandel, Tanner, Lichtenstein, Metz, Katzka, Ginsberg, & Kochman, 2008; Siegel, DeSantis, & Jemal, 2014). Because this lethal disease claims lives of many people every year, more patients are undergoing screening colonoscopies, which have greatly aided in decreasing the number of colorectal cancer deaths (Siegel et al., 2014). The most common form of sedation for colonoscopies is moderate sedation with a benzodiazepine and an opioid (Cohen, Hightower, Wood, Miller, & Aisenberg, 2004; Lera dos Santos, et. al., 2013). However, sedation by anesthesia providers using propofol is becoming more …

In The Postoperative Cardiothoracic Surgical Patient Being Mechanically Ventilated, Is There A Difference In Outcomes When Comparing Sedation With Dexmedetomidine Versus Propofol?, Benjamin Heinrich Riebesel

Doctoral Projects

Patients undergoing a cardiothoracic operation typically require mechanical ventilation in the postoperative phase. Each year approximately 395,000 of these operations are performed in the United States alone. As many as 10% of these patients require reoperation within the first few hours of recovery due to complications (Barash & Cullen, 2013). This comprehensive review of the literature was performed to determine whether postoperative sedation with dexmedetomidine leads to better patient outcomes than sedation with propofol. Inclusion criteria included publications written in the English language, articles available in full text, articles written within the last 10 years, and publications with a focus …

A Pilot Study Of Propofol As An Anti-Emetic In Laparoscopic, Gynecologic Surgery Patients, Flem-Flam Aaron Flemister

Doctoral Projects

The goal of this project was to use sub-hypnotic doses of propofol to decrease post operative nausea and vomiting (PONV) rates in the immediate post-operative period in females, ages 18-65, undergoing laparoscopic gynecologic surgery.

PONV is one of the largest complications of anesthesia affecting 20-30% of all surgical patients. Risk factors associated with PONV are female gender, laparoscopy, general anesthesia, opioids, volatile agents, and post-operative pain; all of which are frequently encountered. The incidence of PONV can prolong recovery time, delay discharge, increase patient cost, decrease patient satisfaction, and can cause significant medical complications. Propofol has previously demonstrated anti-emetic properties; …

Inhalation Anesthesia Vs. Total Intravenous Anesthesia For Ambulatory Dental Surgery In Children, Kristin D. Neal

Theses, Dissertations and Capstones

Abstract: The purpose of this study was to compare inhalation anesthesia with sevoflurane versus Total Intra Venous Anesthesia (TIVA) with propofol infusion as it relates to the quality of recovery including postoperative pain, Post Operative Nausea and Vomiting (PONV), and Post Anesthesia Care Unit (PACU) Length Of Stay (LOS) in pediatric patients undergoing ambulatory dental surgery. Introduction: Pediatric dental procedures are increasingly performed in an outpatient setting under general anesthesia due to inadequate cooperation, circumstantial anxiety, and other behavioral and health issues. Commonly used inhalation anesthetics, such as sevoflurane, can induce hyperalgesia in children. While sevoflurane increases the risk PONV, …
