OBJECTIVE To analyze the clinical agreement between the conventional intermittent bolus thermodilution (TD) technique and a new arterial pressure waveform analysis (APCO) technique (FloTrac; Edward Lifesciences, Irvine, CA) for cardiac output (CO) estimation. DESIGN Prospective observational clinical study. SETTING Cardiac surgery operating room of a(More)
OBJECTIVE To evaluate the safety and efficacy of ketamine in pediatric patients undergoing interventional cardiac procedures. DESIGN A retrospective clinical study. SETTING A single, tertiary referral center. PARTICIPANTS Patients (n = 107) undergoing interventional cardiac procedures between July 1996 and July 1998. INTERVENTIONS Each patient(More)
OBJECTIVE The purpose of this study was to compare hemodynamic data derived from the transesophageal Doppler monitor (Medicina TECO, Berkshire, United Kingdom) against those obtained from a pulmonary artery catheter after coronary artery bypass grafting (CABG). DESIGN Prospective, nonrandomized, clinical study. SETTING Single, tertiary referral center.(More)
BACKGROUND Diaphragm is the most important part of the respiratory system. Diaphragmatic palsy following cardiac surgery is not uncommon and can cause deterioration of pulmonary functions and attendant pulmonary complications. OBJECTIVES Aim of this study was to observe the incidence of diaphragmatic palsy after off pump coronary artery bypass grafting(More)
OBJECTIVE To compare intermittent cardiac output (ICO) with continuous cardiac output (CCO) and stat cardiac output (SCO) measurements in patients undergoing minimally invasive direct coronary artery bypass (MIDCAB) surgery. DESIGN Prospective, clinical study. SETTING Single, tertiary referral center. PARTICIPANTS Twenty adult patients undergoing(More)
Transthoracic electrical bioimpedance (TEB) has been proposed as a non-invasive, continuous, and cost-effective method of cardiac output (CO) measurement. In this prospective, non-randomized, clinical study, we measured CO with NICOMON (Larsen and Toubro Ltd., Mysore, India) and compared it with thermodilution (TD) method in patients after off-pump coronary(More)
The induction and intubation characteristics of sevoflurane were studied prospectively in 23 children, aged 3 months to 6 years (mean 24 +/- 20.25), undergoing repair of congenital cardiac defects. After premedication with syrup chloral hydrate (75mg/kg orally), anaesthesia was induced with 8% sevoflurane and 50% nitrous oxide in oxygen. Nasal endotracheal(More)
Valvular heart disease in systemic lupus erythematosus (SLE) is associated with substantial morbidity and mortality. Current therapy includes symptomatic measures and valve replacement. SLE can present major challenges because of accrued organ damage, coagulation defects and complex management regimes. The peri-operative goals are to maintain strict(More)
Utility of intraoperative echocardiography (IOE) in perioperative management of congenital heart disease has been reported in literature. However, its consistent use as a monitoring tool has not yet been reported from our country. The aim of this study was to evaluate the role of routine use of IOE for intraoperative assessment of surgical repairs in terms(More)
