Implementation of a multifaceted program to sustainably improve appropriate intraoperative antibiotic redosing.

Background: National guidelines recommend intraoperative redosing of prophylactic antibiotics at defined intervals to reduce the risk of surgical site infections. Compliance with these guidelines is poor.

Methods: A quality improvement project-including education, progress reports, and automated redosing reminders in the anesthesia electronic health record-was implemented at a large university-affiliated hospital to increase rates of intraoperative antibiotic redosing for surgeries lasting more than 4 hours.

Intraabdominal Hypertension, Abdominal Compartment Syndrome, and the Open Abdomen.

Abdominal compartment syndrome (ACS) is the end point of a process whereby massive interstitial swelling in the abdomen or rapid development of a space-filling lesion in the abdomen (such as ascites or a hematoma) leads to pathologically increased pressure. This results in so-called intraabdominal hypertension (IAH), causing decreased perfusion of the kidneys and abdominal viscera and possible difficulties with ventilation and maintenance of cardiac output. These effects contribute to a cascade of ischemia and multiple organ dysfunction with high mortality.

Acute hypotension associated with intraoperative cell salvage using a leukocyte depletion filter during management of obstetric hemorrhage due to amniotic fluid embolism.

Amniotic fluid embolism (AFE) is a rare but catastrophic obstetric complication that can lead to profound coagulopathy and hemorrhage. The role of cell salvage and recombinant human Factor VIIa (rFVIIa) administration in such cases remains unclear. We present a case of AFE and describe our experience with the use of cell salvage and rFVIIa administration during the resuscitation.

Perioperative atrial fibrillation and epidural anesthesia: case report and review of the literature.

A case of new-onset atrial fibrillation subsequent to activation of neuraxial anesthesia is presented. The development of atrial fibrillation was temporally related to placement and dosing of an epidural catheter, and may have been triggered by a vagal response to dosing of the anesthetic or the resulting treatment with fluid and an adrenergic agent. The literature on the acute preoperative management of atrial fibrillation and the implications of atrial fibrillation for the patient undergoing regional anesthesia are reviewed.

Remimazolam, a short-acting GABA(A) receptor agonist for intravenous sedation and/or anesthesia in day-case surgical and non-surgical procedures.

Remimazolam (CNS-7056) is a short-acting GABA(A) receptor agonist, under development by PAION, in collaboration with Japanese licensee Ono Pharmaceutical, as an intravenous sedative agent for potential use in day-case procedures, and the induction and maintenance of anesthesia. A member of the benzodiazapene class of drugs, the structure of remimazolam was modified to produce a drug that displays organ-independent metabolism. The incorporation of a carboxylic ester moiety into the benzodiazapene core of remimazolam renders it susceptible to non-specific tissue esterases and it is rapidly metabolized into its pharmacologically inactive metabolite CNS-7054.
