A Randomized Controlled Trial Comparing Haemodynamic Stability In Elderly Patients Undergoing Spinal Anaesthesia At L5, S1 Versus Spinal Anaesthesia At L3, 4 At A Tertiary African Hospital., Vitalis Mung’Ayi, Karen Mbaya, Sharif Thikra, Dorothy Kamya

Anaesthesiology, East Africa

Background: Spinal anaesthesia is a routinely used anaesthetic technique in elderly patients (> 60 years) undergoing operations involving the lower limbs, lower abdomen, pelvis and the perineum. Spinal anaesthesia has several advantages over general anaesthesia including stable haemodynamic variables, less blood loss, less post-operative pain, faster recovery time and less post-operative confusion. Despite these advantages, the sympathetic blockade induced by spinal anaesthesia can result in hypotension, bradycardia, dysrhythmias and cardiac arrests. Conventionally, spinal anaesthesia is performed at the level of L3,4 interspace; with a reported incidence of hypotension in the elderly ranging between 65% and 69%. A possible strategy for …

Univariate analysis was utilized to compare patient demographics and blood product transfusion totals between the PRE and POST cohorts. Multivariate logistic regression …

Certain General Anesthetics Used In Pediatrics Hinder Neurological Development In Infants, Michael R. Hirschi

Selected Honors Theses

General anesthetics act by either blocking N-methyl-d-aspartate (NMDA) receptors or over stimulating γ-aminobutyric acid (GABA) receptors.^1–3 The actions of these receptors are responsible for the anesthetized state and are also crucial in the neurological development of infants.^2,4–8 Animal studies, although limited, provide vital information about general anesthesia’s neurotoxicity its hindrance of neurological development. Exposure to general anesthesia can severely hinder proper neuronal migration, synaptogenesis, and can drastically increase neuronal apoptosis in infant animals.^9–16 General anesthetics are more neurotoxic to infant animals in combination compared to individually.^10,16,17 Additionally, multiple exposures to general anesthesia tend to have compounding …

Does The Addition Of Dexamethasone To Local Anesthetic Used For Peripheral Nerve Block Prolong Analgesia In The Surgical Patient?, Janice M. Oliveira

Nurse Anesthesia MSNA Student Capstones

Pain after orthopedic surgery can be intense. Many anesthesia providers and orthopedic surgeons support the use of peripheral nerve blockade to assist in decreasing the amount of pain a patient may experience post operatively. Select medication adjuncts are being added to peripheral nerve blocks to prolong analgesia. The research presented here focuses on the addition of dexamethasone to peripheral nerve blocks to prolong analgesia. Dexamethasone is a synthetic glucocorticoid that acts as an anti-inflammatory. It has been shown to inhibit the release of inflammatory mediators such as, interleukins and cytokines, facilitating the release of anti-inflammatory mediators, decreasing postoperative pain. Recent …

Understanding And Treating Emergence Delirium, Peter Currie

Nurse Anesthesia MSNA Student Capstones

This paper examines our current understanding of the phenomena of emergence delirium, which can occur following general anesthesia. Much research has been conducted to elucidate the causative factors of this condition, with findings ranging from anxiety to volatile agents and the neurodevelopment of the brain (Aono, Ueda, & Mamiya, 1997; Kain et al., 2004; McLott, Jurecic, Hemphill, & Dunn, 2013). While much of our understanding of emergence delirium has come from studying children, who are more prone to this condition, we can attempt to learn even more by examining the increased incidence of emergence delirium that occurs in those with …

More than half of the population in the United States of America drinks alcohol regularly. Thousands of deaths annually are linked to drug overdoses, and that number continues to rise. Anesthesia professionals can expect to see patients in various levels of substance abuse and recovery during their practice. This case study is presented to discuss a minimal narcotic technique given in a patient with a history of prescription drug abuse, who had been substance free since successfully been through a recovery program years prior.

Detection And Treatment Of Hemorrhage In The Postoperative Patient, Vanessa M. Derosby

Nurse Anesthesia MSNA Student Capstones

Hemorrhage is a devastating event that can occur in the perioperative period. It is estimated that 2.35 in 1000 patients will experience hemorrhage associate with surgery. Adverse outcomes affecting patient morbidity, mortality and quality of life are associated with hemorrhage. Timely detection, diagnosis and appropriate intervention in the setting of hemorrhage are imperative to reduce adverse outcomes of shock such as end organ damage, chronic disability or death. Anesthesia practitioners hold the charge of monitoring and managing the patient’s hemodynamic status and play an integral role in the detection and management of the hemorrhaging patient.

Opioid-Induced Hyperalgesia, Lisa Nieder

Nurse Anesthesia MSNA Student Capstones

Opioids are a fundamental part in the treatment of pain especially within the perioperative setting. While opioids are routinely administered by nurse anesthetists for the treatment of pain, they can be associated with several undesirable side effects including opioid- induced hyperalgesia (OIH). OIH is a complex phenomenon that has a significant impact on the successful treatment of pain in a surgical setting. While there have been many advances in recent years into the topic of OIH, the mechanisms are complex and remain incompletely understood. OIH is believed to occur from changes in both the peripheral and central nervous systems that …

Buprenorphine And The Anesthesia Considerations: A Literature Review, Elizabeth E. Stern

Nurse Anesthesia MSNA Student Capstones

Buprenorphine is a unique pharmaceutical in the management of chronic pain and opioid use disorder (OUD). Buprenorphine is a semisynthetic partial opioid agonist at the mu opioid receptor and an antagonist of the kappa opioid. Buprenorphine Maintenance Therapy (BMT) is utilized for the long-term treatment of patients with OUD. The attraction to this methadone alternative is increased safety profile, more convenient patient access to the drug, as well as increase of ease for the provider. The particular formula used in the US, Suboxone, has properties to discourage intravenous injection to prevent abuse and prevent negative secondary effects of intravascular injections …

Chiral Symmetry Breaking And Chiral Polarization: Tests For Finite Temperature And Many Flavors, Andrei Alexandru, Ivan Horváth

Anesthesiology Faculty Publications

It was recently conjectured that, in SU(3) gauge theories with fundamental quarks, valence spontaneous chiral symmetry breaking is equivalent to condensation of local dynamical chirality and appearance of chiral polarization scale Λ_ch. Here we consider more general association involving the low-energy layer of chirally polarized modes which, in addition to its width (Λ_ch), is also characterized by volume density of participating modes (Ω) and the volume density of total chirality (Ω_ch). Few possible forms of the correspondence are discussed, paying particular attention to singular cases where Ω emerges as the most versatile …

Prehospital Use Of Plasma In Traumatic Hemorrhage (The Pupth Trial): Study Protocol For A Randomised Controlled Trial, Penny S. Reynolds, Mary Jane Michael, Emily D. Cochran, Jacob A. Wegelin, Bruce D. Spiess

Anesthesiology Publications

Background

Severe traumatic injury and haemorrhagic shock are frequently associated with disruptions of coagulation function (such as trauma-induced coagulopathy TIC) and activation of inflammatory cascades. These pathologies may be exacerbated by current standard of care resuscitation protocols. Observational studies suggest early administration of plasma to severely-injured haemorrhaging patients may correct TIC, minimise inflammation, and improve survival. The proposed randomised clinical trial will evaluate the clinical effectiveness of pre-hospital plasma administration compared with standard- of-care crystalloid resuscitation in severely-injured patients with major traumatic haemorrhage.

Methods/design

This is a prospective, randomized, open-label, non-blinded trial to determine the effect of pre-hospital administration of …
