Catheterization Procedure (catheterization + procedure)
Selected AbstractsEvaluation of Propofol-Ketamine Anesthesia for Children Undergoing Cardiac Catheterization ProceduresJOURNAL OF INTERVENTIONAL CARDIOLOGY, Issue 2 2007F.F.A. (DUBLIN), F.R.C.A. (LOND), Parthasarathi GAYATRI M.D. The aim of this study was to assess the safety and efficacy of the continuous intravenous administration of a combination of propofol and ketamine for children undergoing cardiac catheterization procedures (CCP). Thirty-two children scheduled for CCP in a university teaching hospital were included in this prospective randomized study. Patients in group 1 (n = 15) were given a combination of propofol (25 ,g/kg per minute) and ketamine (25 ,g/kg per minute), whereas patients in group 2 (n = 17) received a combination of propofol (25 ,g/kg per minute) and ketamine (12.5 ,g/kg per minute) for the maintenance of anesthesia. There were no statistically significant differences with age, weight, duration of the procedure, and the number of diagnostic and interventional procedures between the two groups. There was no hemodynamic instability, airway compromise, excessive salivation, or arterial desaturation in either of the two groups. There was more incidence of movements in patients who received less dose of ketamine; however, it did not reach to statistically significant level. The total dose of ketamine used in group 1 was 309.25 ± 90.97 ,g/min, whereas in group 2, it was 148.06 ± 34.05 ,g/min. The time to awakening was significantly less in group 2 (P < 0.05). We conclude that a combination of propofol (25 ,g/kg per minute) and two different doses of ketamine (25 and 12.5 ,g/kg per minute, respectively) are safe and efficacious for CCP in children. Although the time to awaken was more in patients receiving 25 ,g/kg per minute of ketamine compared to those receiving 12.5 ,g/kg per minute of ketamine, it was well within acceptable limits.

Miranda Abstract The aim of this study was to induce and synchronize spawning of pejerrey Odontesthes bonariensis (Valenciennes, 1835), using gonadotropin releasing hormone agonist (GnRHa) implants. In the first experiment, the ovarian condition was assessed by ovarian biopsies and the measurement of the genital pore width (GPW). Females having the leading clutch of oocytes with a diameter of around 800,900 ,m and a GPW between 4.5 and 5.5 mm were treated with GnRHa implants. Eighty per cent of females spawned between 2 and 9 days after treatment, 12 days earlier than 20% of the fish in the control group that presented signs of spawning activity. In order to avoid any possible ovarian injury and/or stress by the catheterization procedure, in a second experiment, females were selected only by visual inspection of the abdomen and GPW measurement. As in experiment 1, 80% of females spawned between 2 and 8 days after treatment, 8 days earlier than 30% of the fish that spawned in the control group. In both experiments, fertilization and hatching success were similar between control and GnRHa-treated groups. These results clearly demonstrated that GnRHa implantation can advance and synchronize ovulation and spawning in pejerrey without affecting egg quality.

In case that such an event occurs, leading to inability to remove the catheter, various different methods have been described to solve the problem, varying from the least invasive to open heart surgery. The formation of large knots requires surgical removal in the vast majority of cases. We describe the successful nonsurgical removal of a Swan-Ganz catheter, after the formation of a large double knot, during a right heart catheterization performed without fluoroscopic guidance in the intensive care unit. This technique could serve as a last resort in cases that surgical removal seems inevitable due to size-related inapplicability of other nonsurgical methods. © 2009 Wiley-Liss, Inc. [source] New Technology and Methodologies for Intraoperative, Perioperative, and Intraprocedural Monitoring of Surgical and Catheter Interventions for Congenital Heart DiseaseECHOCARDIOGRAPHY, Issue 8 2002Mary J. Rice M.D. We review the new technology and methods available for support of intraoperative and intraprocedural imaging in the catheterization laboratory for surgical and interventional catheterization procedures in the treatment of congenital heart disease. The methods reviewed include miniaturized probes and new ways of using them perioperatively for cardiac imaging from transesophageal, substernal, and intracardiac imaging locations. The smaller and more versatile the probes, the better adapted they will be in providing methods to improve the outcomes in babies born with serious forms of congenital heart disease.
