Ashley A. Colletti, Taniga Kiatchai, Vivian H. Lyons, Bala G. Nair, more

Pediatric Anesthesia > 29 > 3 > 271 - 279

Background Traumatic brain injury anesthesia care is complex. The use of clinical decision support to improve pediatric trauma care has not been examined. Aims The aim of this study was to examine feasibility, reliability, and key performance indicators for traumatic brain injury anesthesia care using clinical decision support. Methods Clinical decision support was activated for patients under...

Perioperative hypotension and discharge outcomes in non-critically injured trauma patients, a single centre retrospective cohort study

Nadav Sheffy, Itay Bentov, Brianna Mills, Bala G. Nair, more

Injury > 2017 > 48 > 9 > 1956-1963

There is a lack of information on the effect of age on perioperative care and outcomes after minor trauma in the elderly. We examined the association between perioperative hypotension and discharge outcome among non-critically injured adult patients.We conducted a retrospective study of non-critically ill patients (ISS <9 or discharged within less than 24h) who received anaesthesia care for surgery...

Continuous intraoperative epidural infusions affect recovery room length of stay and analgesic requirements: a single-center observational study

Aalap C. Shah, Bala G. Nair, Charles F. Spiekerman, Laurent A. Bollag

Journal of Anesthesia > 2017 > 31 > 4 > 494-501

Purpose Continuous intraoperative epidural analgesia may improve post-operative pain control and decrease opioid requirements. We investigate the effect of epidural infusion initiation before or after arrival in the post-anesthesia care unit on recovery room duration and post-operative opioid use. Methods We performed a retrospective chart review of abdominal, thoracic and orthopedic surgeries where...

Relative costs of anesthesiologist prepared, hospital pharmacy prepared and outsourced anesthesia drugs

Srdjan Jelacic, Karen Craddick, Bala G. Nair, Mark Bounthavong, more

Journal of Clinical Anesthesia > 2017 > 36 > C > 178-183

Anesthesia drugs can be prepared by anesthesia providers, hospital pharmacies or outsourcing facilities. The decision whether to outsource all or some anesthesia drugs is challenging since the costs associated with different anesthesia drug preparation methods remain poorly described.The costs associated with preparation of 8 commonly used anesthesia drugs were analyzed using a budget impact analysis...

Risks of Routinely Clamping External Ventricular Drains for Intrahospital Transport in Neurocritically Ill Cerebrovascular Patients

Nophanan Chaikittisilpa, Abhijit V. Lele, Vivian H. Lyons, Bala G. Nair, more

Neurocritical Care > 2017 > 26 > 2 > 196-204

Background Current guidelines recommend routine clamping of external ventricular drains (EVD) for intrahospital transport (IHT). The aim of this project was to describe intracranial hemodynamic complications associated with routine EVD clamping for IHT in neurocritically ill cerebrovascular patients. Methods We conducted a retrospective review of cerebrovascular adult patients with indwelling EVD...

Katherine Grunzweig, Bala G. Nair, Gene N. Peterson, Mayumi Horibe, more

Journal of Clinical Anesthesia > 2016 > 32 > C > 214-223

To understand the decisional practices of anesthesia providers in managing intraoperative glucose levels.This is a retrospective cohort study.Operating rooms in an academic medical center.Adult patients undergoing surgery.Intraoperative blood glucose management based on an institutional protocol.Glucose management data was extracted from electronic medical records to determine compliance to institutional...

Intraoperative blood glucose management: impact of a real-time decision support system on adherence to institutional protocol

Bala G. Nair, Katherine Grunzweig, Gene N. Peterson, Mayumi Horibe, more

Journal of Clinical Monitoring and Computing > 2016 > 30 > 3 > 301-312

Poor perioperative glycemic management can lead to negative surgical outcome. Improved compliance to glucose control protocol could lead to better glucose management. An Anesthesia Information Management System based decision support system—Smart Anesthesia Manager™ (SAM) was used to generate real-time reminders to the anesthesia providers to closely adhere to our institutional glucose management...

Smart Anesthesia Manager $^{\rm TM}$ (SAM)—A Real-time Decision Support System for Anesthesia Care during Surgery

Bala G. Nair, Shu-Fang Newman, Gene N. Peterson, Howard A. Schwid

IEEE Transactions on Biomedical Engineering > 2013 > 60 > 1-2 > 207 - 210

Anesthesia information management systems (AIMS) are being increasingly used in the operating room to document anesthesia care. We developed a system, Smart Anesthesia Manager $^{\rm TM}$ (SAM) that works in conjunction with an AIMS to provide clinical and billing decision support. SAM interrogates AIMS database in near real time, detects issues related to clinical care, billing and compliance, and material...

Near real-time notification of gaps in cuff blood pressure recordings for improved patient monitoring

Bala G. Nair, Mayumi Horibe, Shu-Fang Newman, Wei-Ying Wu, more

Journal of Clinical Monitoring and Computing > 2013 > 27 > 3 > 265-271

Blood pressure monitoring during anesthesia is an American Society of Anesthesiology standard. However, the anesthesia provider sometimes fails to engage the patient monitor to make periodic (generally every 3–5 min) measurements of Non-Invasive Blood Pressure (NIBP), which can lead to extended periods (>5 min) when blood pressure is not monitored. We describe a system to automatically detect such...

Improving Documentation of a Beta-Blocker Quality Measure Through an Anesthesia Information Management System and Real-Time Notification of Documentation Errors

Bala G. Nair, Gene N. Peterson, Shu-Fang Newman, Wei-Ying Wu, more

The Joint Commission Journal on Quality and Patient Safety > 2012 > 38 > 6 > 283-288, AP1-AP3

Continuation of perioperative beta-blockers for surgical patients who are receiving beta-blockers prior to arrival for surgery is an important quality measure (SCIP-Card-2). For this measure to be considered successful, name, date, and time of the perioperative beta-blocker must be documented. Alternately, if the beta-blocker is not given, the medical reason for not administering must be documented...

Matching a Wavelet to ECG Signal

George F. Takla, Bala G. Nair, Kenneth A. Loparo

2006 International Conference of the IEEE Engineering in Medicine and Biology Society > Supplement > 1686 - 1689

Conference Proceedings. Annual International Conference of the IEEE Engineering in Medicine and Biology Society

In this paper we develop an approach to synthesize a wavelet that matches the ECG signal. Matching a wavelet to a signal of interest has potential advantages in extracting signal features with greater accuracy, particularly when the signal is contaminated with noise. The approach that we have taken is based on the theoretical work done by Chapa and Rao [10]. We have applied their technique to a noise-free...

Automatic detection of QRS complexes in ECG signals collected from patients after cardiac surgery

Mirela Visinescu, C. Allen Bashour, Mohamed Bakri, Bala G. Nair

2006 International Conference of the IEEE Engineering in Medicine and Biology Society > Supplement > 3724 - 3727

Conference Proceedings. Annual International Conference of the IEEE Engineering in Medicine and Biology Society

A novel automatic QRS detection algorithm that is based on a wavelet pre-filter and an adaptive threshold technique is presented. The algorithm utilizes a bi-orthogonal wavelet filter to de-noise the ECG signal. The QRS complexes are then identified by computing the first derivative of the signal and applying a set of adaptive thresholds that are not limited to a strict range. QRS complexes are identified...
