The Joint Commission International (JCI) is responsible for upholding standards in healthcare and organizations in compliance receive accreditation. JCI requires quality improvement on patient safety goals, but requirements may prolong the total procedure/surgery time and reduce efficiency. Here, we evaluate the impact of JCI requirements on time periods in the operating room. We included patients who received elective and emergency surgeries under general anesthesia at Juntendo University Hospital between December 2014 and June 2016. Patients were classified as before and after JCI accreditation on December 12, 2015. The primary outcome was total procedure/surgery time. Secondary outcomes include five ...

Every year, millions of children undergo anesthesia for a multitude of procedures. However, studies in both animals and humans have called into question the safety of anesthesia in children, implicating anesthetics as potentially toxic to the brain in development. To date, no studies have successfully elucidated the mechanism(s) by which anesthesia may be neurotoxic. Animal studies allow investigation of such mechanisms, and neonatal piglets represent an excellent model to study these effects due to their striking developmental similarities to the human brain.

This protocol adapts the use of enzyme-based microelectrode array (MEA) technology as a novel way to study ...


Dexmedetomidine (Precedex) Induced Fever, Patrick DeAlmeida DO, Michael Matrale DO 2018 Rowan University SOM

Dexmedetomidine (Precedex) Induced Fever, Patrick Dealmeida Do, Michael Matrale Do

Stratford Campus Research Day

Precedex is an intravenous, α-2 receptor agonist broadly used for analgesia, maintenance of sedation, and alcohol withdrawal treatment in the intensive care unit (ICU).

The most commonly reported adverse effects associated with precedex are hypotension and bradycardia1.

Fever has been reported with a 5-7% incidence rate. Our case shows a very impressive pyrexia in a 49 year old patient most likely associated to Precedex. When compared to the previously three reported cases his fever reached the largest value (T= 107ºF).

As its use becomes more and more common in the ICU, clinicians should be aware of this adverse effect especially ...

Clinicians often hesitate prescribing corticosteroids to treat corticosteroid-responsive conditions in sickle cell disease (SCD) patients because their use can be associated with complications (increased hospital readmission, rebound pain, strokes, avascular necrosis, acute chest syndrome). Consequently, SCD patients may receive suboptimal treatment for corticosteroid-responsive conditions. We conducted a preclinical trial of dissociative (vamorolone) and conventional (prednisolone) corticosteroid compounds to evaluate their effects on nociception phenotype, inflammation, and organ dysfunction in SCD mice. Prednisolone and vamorolone had no significant effects on nociception phenotype or anemia in homozygous mice. Conversely, prednisolone and vamorolone significantly decreased white blood cell counts and hepatic inflammation. Interestingly ...

Morphine Versus Fentanyl Patient-Controlled Analgesia For Postoperative Pain Control In Major Hepatic Resection Surgeries Including Living Liver Donors: A Retrospective Study, Eman M. Nada, Abdulmajeed Alabdulkareem 2018 University of Massachusetts Medical School

Morphine Versus Fentanyl Patient-Controlled Analgesia For Postoperative Pain Control In Major Hepatic Resection Surgeries Including Living Liver Donors: A Retrospective Study, Eman M. Nada, Abdulmajeed Alabdulkareem

Open Access Articles

Background: Liver resection surgery results in significant postoperative pain. However, it is still not clear which opioids used by patient-controlled analgesia (PCA) provides the best pain control and results in the least side effect in a patient with impaired liver function. Our hypothesis was that fentanyl is a better choice than morphine as it is a potent analgesic that its elimination half-life does not depend on the hepatic uptake and metabolism.

The Study Purpose: Is to compare morphine and fentanyl PCA in liver resection patients as regards the degree of pain control, the consumption of opioids, and the side effects ...

Administering Dexamethasone Prior To Peripheral Nerve Blocks, Jacob Millwood 2017 The University of Southern Mississippi

Administering Dexamethasone Prior To Peripheral Nerve Blocks, Jacob Millwood

Doctoral Projects

Post-operative pain creates burdens for the patient and their family members while also drastically increasing the price of cost to the healthcare system. The Institute of Medicine Committee on Advancing Pain Research, Care, and Education states that the annual economic cost of chronic pain in adults is $560-630 billion (IOM, 2011). Regional anesthesia has been shown to provide potent analgesia that often times leads to a reduction in systemic analgesic requirements, opioid related side effects, general anesthesia requirements, and possibly the incidence of chronic post-operative pain. There are several adjunct medications that can be combined with peripheral nerve blocks to ...

Peri-Operative Regional Nerve Blocks (Pnb) In The Treatment Of Pain In Patients Undergoing Operative Fixation Of Lower Extremity Fractures, Joshua K. Radi 2017 Western Michigan University

Peri-Operative Regional Nerve Blocks (Pnb) In The Treatment Of Pain In Patients Undergoing Operative Fixation Of Lower Extremity Fractures, Joshua K. Radi

Dissertations

This research explores current approaches to managing pain control in patients undergoing operative fixation of lower extremity fractures. As opioid use in the U.S. and abroad increases, alternative methods of treating and preventing opioid requirements are being examined. Patients with lower extremity fractures are susceptible to nonunion when anti-inflammatories are consumed, so alternative approaches are warranted. One such alternative, a peri-operative regional nerve block (PNB), is accomplished by injecting local anesthetic adjacent to one or more peripheral nerves supplying the area of the fracture to decrease pain (Fowler, Symons, Sabato, & Myles, 2008). The goal of this research was to ...

Background

The clearance of cytochrome P450 (CYP) 3A substrates is reported to be reduced with lower age, inflammation and obesity. As it is unknown what the overall influence is of these factors in the case of obese adolescents vs. morbidly obese adults, we studied covariates influencing the clearance of the CYP3A substrate midazolam in a combined analysis of data from obese adolescents and morbidly obese adults.

Methods

Data from 19 obese adolescents [102.7 kg (62–149.5 kg)] and 20 morbidly obese adults [144 kg (112–186 kg)] receiving intravenous midazolam were analysed, using population pharmacokinetic modelling (NONMEM 7 ...
