Interventions to prevent hypothermia in extremely preterm low-weight infants undergoing cardiac catheterisation.

Background: In January 2019, a new device called the Amplatzer Piccolo Occluder was approved by the US Food and Drug Administration for percutaneous closure of patent ductus arteriosus in infants weighing more than 700 g and of postnatal age more than 3 days. Premature low-weight infants are predisposed to hypothermia when transported outside of the thermo-neutral environment. At our institution, 90% of extremely preterm low-weight infants developed transient moderate hypothermia in the cardiac catheterisation suite.

A Novel Process Audit for Standardized Perioperative Handoff Protocols.

A perioperative handoff protocol provides a standardized delivery of communication during a handoff that occurs from the operating room to the postanestheisa care unit or ICU. The protocol's success is dependent, in part, on its continued proper use over time. A novel process audit was developed to help ensure that a perioperative handoff protocol is used accurately and appropriately over time.

Effects of Circuit Leak Development Over Time and Response During Low-Flow Volume and Pressure-Controlled Ventilation.

Study Objective: To study the effects of circuit leak development over time and response during volume and pressure controlled ventilation using low flow in human patient simulator and to examine the minimum fresh gas flow needed to compensate for such a leak. Design/Setting: Prospective study using a patient Simulation Lab at Wayne State University. Measurements: A human patient simulator was endotracheally intubated.

Intraoperative patient information handover between anesthesia providers.

Currently, no reported studies have evaluated intraoperative handover among anesthesia providers. Studies on anesthetic handover in the US recovery room setting observed that handover processes are insufficient and, in many instances, significant intraoperative events are disregarded. An online survey tool was sent to anesthesia providers at US anesthesia residency programs nationwide (120 out of the 132 US programs encompassing around 4500 residents and their academic MDAs) and a smaller survey selection of CRNAs (10 institutions about 300 CRNAs in the metropolitan area of Detroit, MI, USA) to collect information on handover practices.

STOP-Bang and prediction of difficult airway in obese patients.

Study Objective: To determine if a high score (≥ 3) on the STOP-Bang screening questionnaire for obstructive sleep apnea (OSA) predicts whether obese patients are at high risk for OSA and increased risk of difficult airway.

Design: Prospective, questionnaire-based clinical assessment.

Setting: University-affiliated hospital.

Effective low dosage of mepivacaine in ultrasound-guided axillary nerve block: a double-blinded, randomized clinical trial of efficacy in patients undergoing distal upper extremity surgery.

Study Objective: To evaluate two low-dose volumes (20 mL or 30 mL) of 1.5% mepivacaine solution used for ultrasound-guided axillary blockade for outpatients undergoing distal upper limb surgery.

Design: Prospective, double-blinded randomized study.

Nicotinic acetylcholine receptor gene expression is altered in burn patients.

Introduction: Burn patients have been observed to be more susceptible to the hyperkalemic effect of the depolarizing muscle relaxant succinylcholine. Changes in nicotinic acetylcholine receptor (nAChR) subunit composition may alter electrophysiologic, pharmacologic, and metabolic characteristics of the receptor inducing hyperkalemia on exposure to succinylcholine. No studies have been performed that show the upregulation and/or alteration of nAChR subunit composition in human burn patients.
