Tricuspid Annular Plane Systolic Excursion (TAPSE) for the Assessment of Right Ventricular Function in Adult and Pediatric Cardiac Surgery: Modified Two-dimensional and M-mode TAPSE by Transesophageal Echocardiography Compared to M-mode TAPSE by Transthoracic Echocardiography.

Objectives: To compare transesophageal echocardiography-guided 2-dimensional and M-mode tricuspid annular plane systolic excursion (TAPSE) to transthoracic echocardiography (TTE)-guided M-mode TAPSE in terms of accuracy, interobserver, and intra-observer variability.

Design: A prospective, observational study.

Setting: Adult and pediatric operating rooms.

A comparison of sevoflurane versus sevoflurane-propofol combination on renal function in patients undergoing valvular heart surgery-A prospective randomized controlled pilot study.

Aim: The objective of the present study was to compare the effect of sevoflurane with the sevoflurane-propofol combination on renal function in patients undergoing valvular heart surgery. The renal protective effect was assessed using a novel marker called neutrophil gelatinase-associated lipocalin (NGAL).

Materials And Methods: This was a prospective randomized controlled pilot study conducted at a tertiary care center in India.

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.

Effect of operating microscope light on brain temperature during craniotomy.

Background: Operating microscopes used during neurosurgery are fitted with xenon light. Burn injuries have been reported because of xenon microscope lighting as the intensity of xenon light is 300 W. We designed this study to find out if the light of operating microscope causes an increase in temperature of the brain tissue, which is exposed underneath.

Oral clonidine attenuates the fall in mean arterial pressure due to scalp infiltration with epinephrine-lidocaine solution in patients undergoing craniotomy: a prospective, randomized, double-blind, and placebo controlled trial.

Background: Scalp infiltration with epinephrine-lidocaine solution in patients undergoing neurosurgery may result in transient but significant hypotension. We investigated whether premedication with alpha2-adrenoreceptor agonist clonidine, which also exhibits alpha1-adrenoreceptor mediated vasoconstriction, would prevent or attenuate this fall in mean arterial pressure (MAP).

Methods: Sixty-six American Society of Anesthesiologists I and II adult patients, 18 to 50 years, undergoing elective tumor decompression were recruited into this prospective, randomized, double-blind, placebo controlled study, and scheduled to receive either oral pantoprazole 40 mg (placebo group) or oral clonidine 3 microg/kg (clonidine group), 90 minutes before induction of anesthesia.

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.
