Normal Saline and Dextrose 5% in Water Do Not Support Bacterial Growth 24 Hours After Being Spiked in the Perioperative Environment.

BACKGROUND: The Joint Commission requirement is that the US Pharmacopeia Chapter <797> is followed, which recommends that administration of compounded sterile preparations should begin no later than 1 hour after their preparation. We hypothesized that simply spiking the IV fluid in a nonsterile environment does not pose an increased risk of infection to the patient. METHODS: Two 1000-mL bags of IV fluid (normal saline and dextrose 5% in water) were spiked and hung in 5 busy perioperative locations, once a week for a 13-week period. A 10-mL sample was drawn from each bag of IV fluid at time zero and 24 hours resulting in 260 samples in total. All samples were inoculated in 2 separate growth media (sheep's blood agar and thioglycollate broth). The primary outcome was growth versus no growth in any of the specimens. If any growth was noted, the sample was marked as positive and further testing to identify the organism was undertaken. RESULTS: A total of 257 samples (normal saline = 127, dextrose 5% in water = 129) were collected over a period of 13 weeks, yielding 514 specimens. Three samples were excluded from the study secondary to the IV bags being discarded accidentally. No growth was identified in any of the specimens. The 97.5% CIs were as follows: normal saline = 127 (0-0.034) and dextrose 5% in water = 129 (0-0.033), correcting for multiple tests. CONCLUSIONS: No bacterial growth was noted in any of the 257 samples collected. Normal saline and dextrose 5% in water do not support bacterial growth 24 hours after their preparation using standard sterile techniques in the perioperative space.

Wireless Monitoring for Office-Based Anesthesia.

Current research on wireless hemodynamic monitoring during anesthesia is limited as the topic is just beginning to be explored. The aim of this article is to stimulate technological advancements in monitored anesthesia care that will increase safety and efficiency. Here, we introduce this exciting new concept and propose an innovative model for monitoring patients undergoing office-based anesthesia.

Postoperative care after left ventricular assist device implantation: considerations for the cardiac surgical intensivist.

Heart failure is a leading cause of morbidity and mortality, the incidence of which is predicted to continue to increase as the population ages. Left ventricular assist devices (LVADs) in particular have emerged as important therapies for the support of patients with advanced heart failure needing short- or long-term mechanical circulatory support. With over 5000 implantations per year, LVADs are the most commonly used durable devices worldwide. In this article, we provide an overview of the intensive care management of patients with LVADs during the early post-implantation period.

Asystole in Orthognathic Surgery: A Case Report.

A previously healthy 26-year-old man presented for elective Le Fort I osteotomy, bilateral mandibular osteotomy, and genioplasty. During the intraoperative course, the patient developed sudden bradycardia and asystole on placement of a bite block. Asystole is an extremely rare consequence of the trigeminocardiac reflex, and awareness of this potentially life-threatening complication is pivotal in its management.

Carotid artery dissection: a rare complication of Eagle syndrome.

Carotid artery dissection is a significant cause of ischaemic stroke in all age groups and accounts for a large percentage of strokes in young patients. Carotid dissection can be caused by trauma, underlying connective tissue disease, hypertension, mechanical injury or can be spontaneous. We present an exceedingly rare case of carotid dissection caused by an elongated styloid process, causing direct mechanical damage to the carotid artery.
