Comparison of Propofol-Based Total Intravenous Anesthesia versus Volatile Anesthesia with Sevoflurane for Postoperative Delirium in Adult Coronary Artery Bypass Grafting Surgery: A Prospective Randomized Single-Blinded Study.

Objectives: To compare the incidence of delirium and early (at 1 week) postoperative cognitive dysfunction (POCD) between propofol-based total intravenous anesthesia (TIVA) and volatile anesthesia with sevoflurane in adult patients undergoing elective coronary artery bypass graft surgery (CABG) with cardiopulmonary bypass (CPB).

Design: This was a prospective randomized single-blinded study.

Setting: The study was conducted at a single institution, the Sree Chitra Tirunal Institute for Medical Sciences and Technology, a tertiary care institution and university-level teaching hospital.

Intraoperative Three-dimensional Imaging of Ventricular Septal Defects in Children Using Epicardial Echocardiography: A Novel Approach.

Objective: To assess the feasibility and accuracy of intraoperative three-dimensional (3D) epicardial en face images of ventricular septal defects (VSD) in children using the 3D transesophageal echocardiography (TEE) probe as an epicardial probe.

Design: This was a prospective nonrandomized blinded observational study.

Setting: The study was conducted at a single tertiary cardiac care center.

Intraoperative assessment of transient and persistent regional left ventricular wall motion abnormalities in patients undergoing coronary revascularization surgery using real time three-dimensional transesophageal echocardiography: A prospective observational study.

Objective: To evaluate the feasibility of intraoperative real time three-dimensional echocardiography (RT3DE) for identification and quantification of transient and persistent regional wall motion abnormalities (RWMAs) in patients with ischemic cardiomyopathy undergoing coronary artery bypass grafting (CABG).

Design: A prospective observational study SETTING: Single-center study in an academic tertiary care hospital PARTICIPANTS: A series of 42 patients undergoing elective CABG over a 2-year period were included.

Intervention: After induction of anesthesia, a comprehensive transesophageal echocardiography (TEE) examination was performed to evaluate regional wall motion using two-dimensional wall motion score index (WMSI) and RT3D echocardiographic parameters at three specific time points during the operative phase.

Gabapentin premedication decreases the hemodynamic response to skull pin insertion in patients undergoing craniotomy.

Background: In patients undergoing craniotomy, skull pin insertion produces significant increases in heart rate (HR) and blood pressure. We investigated whether premedication with gabapentin would prevent or attenuate this increase.

Methods: Forty-seven ASA I and II patients, 18 to 60 years, undergoing elective craniotomy for intracranial tumor surgery were recruited prospectively and randomly divided into 3 groups; L (oral placebo plus 2% lidocaine infiltration at pin sites; n=12), G (oral gabapentin 900 mg plus normal saline infiltration; n=21) and GL (oral gabapentin 900 mg plus 2% lidocaine infiltration; n=14).

Anesthesia for craniotomy in a patient with previous paralytic polio.

Poliomyelitis remains endemic in many developing nations. Patients may develop residual muscle weakness in one or more limbs after an attack of poliomyelitis in childhood. We report an adult patient who presented for right temporal cortical grid placement.

Case report: alterations in bispectral index following absolute alcohol embolization in a patient with intracranial arteriovenous malformation.

Purpose: We report a case of bispectral index (BIS) falling to zero during absolute alcohol embolization of an intracranial arteriovenous malformation (AVM) under anesthesia. This case highlights the unusual effect of a therapeutic dose of parenteral alcohol on the central nervous system using BIS monitoring.

Clinical Features: A 29-yr-old male with a left parieto-occipital arteriovenous malformation underwent neuroendovascular embolization under general anesthesia.

Effect of lung ventilation with 50% oxygen in air or nitrous oxide versus 100% oxygen on oxygenation index after cardiopulmonary bypass.

Objective: This study was designed to assess the use of 100% oxygen or 50% oxygen in air or nitrous oxide after cardiopulmonary bypass (CPB) on atelectasis, as evidenced by the oxygenation index (PaO2/F(I)O2), after coronary artery bypass graft (CABG) surgery.

Design: Prospective, randomized clinical study.

Setting: University teaching hospital.
