Comparison of End-Tidal and Arterial Carbon Dioxide in Infants Using Laryngeal Mask Airway and Endotracheal Tube
Effects of inhaled nitric oxide and intravenous magnesium sulphate, alone and in combination, in a porcine model of hypoxic pulmonary hypertension
In order to compare the effects of inhaled nitric oxide (NO) and magnesium (Mg) and their potential synergism on hemodynamics in pulmonary hypertension, we compared the effect of NO and Mg alone and in combination. The fact that simultaneous administration selectively increases pulmonary vascular relaxation would suggest that their association would allow for a decrease in the NO concentration required for optimal pulmonary vasodilation, thus lowering the risk of side effects
Corrective surgery for idiopathic scoliosis after heart transplantation
Cardiac transplant surgery is being performed with increasing frequency as a treatment for end-stage heart disease. In addition to the well-known post-surgical problems of rejection and infection, these patients may present at a future date with other medical problems which require surgical treatment, including orthopaedic pathology. Severe idiopathic scoliosis has been described in association with congenital heart disease, and its surgical treatment poses considerable risks because of heart disease. Spinal fusion in heart transplant recipients involves similar risks due to the particular physiology and pharmacological reactions of the denervated heart. Several cases of cholecystectomy performed in heart transplant recipients have been described, but to our knowledge no orthopaedic procedures have been reported in such patients. We report on a 15-year-old patient who underwent successful corrective surgery for idiopathic scoliosis 14 months after heart transplant
Epidural sufentanil during paediatric cardiac surgery: effects on metabolic response and postoperative outcome
The metabolic and neuroendocrine effects of caudal epidural analgesia were studied during paediatric cardiac surgery. Combined epidural and general anaesthesia (EPI group; n=12) was compared with deep opioid anaesthesia (DOA group; n=12). During anaesthesia and surgery, haemodynamic stability was similar in the two groups. There was no significant difference between groups concerning the metabolic response to surgery but circulating catecholamines were significantly lower in the EPI group during and after surgery. Perioperative release of IL-6 was higher in the EPI group possibly reflecting a longer aortic clamp time. Incidence of postoperative life-threatening dysrhythmias was very low in the two groups. No significant reduction of postoperative mechanical ventilation, intensive care unit or hospital stays was reported with epidural analgesia. The incidence of postoperative infections was higher than expected in the two groups because of the poor properative clinical status of most of the children included in the study
Cardiac rhythm and left ventricular function of infants at 1 MAC sevoflurane and halothane
The implementation of sevoflurane in pediatric anesthesia practice led to a decrease in the incidence of cardiac arrest previously reported with halothane. Nevertheless, the effects of sevoflurane on cardiac rhythm and function have not been systematically investigated in infants. Thus, we compared cardiac rhythm and left ventricular function at 1 MAC sevoflurane and halothane anesthesia and investigated the potential benefit effect of atropine
