    Notes: Abstract Objective: To evaluate whether a trial of inhaled nitric oxide (NO) differentiates reversible pulmonary vasoconstriction from fixed anatomic obstruction to pulmonary blood flow after surgery for congenital heart disease in patients at risk for pulmonary hypertension.¶Design: Prospective cohort study.¶Setting: Tertiary care children's hospital.¶Patients: 15 neonate and infants with elevated pulmonary artery or right ventricular pressure or with clinical signs suggestive of high pulmonary vascular resistance in the early postoperative period following repair of congenital heart disease.¶Intervention: 30-min trial of 40 ppm inhaled NO.¶Results: 5 patients responded to inhaled NO, 2 patients were weaned from extracorporeal support with NO. Four were maintained on continuous inhaled NO for 3 to 5 days. All the responders survived. Ten patients did not respond to NO. An important anatomic obstruction was found with echocardiography or angiography in all 10 patients. Reintervention was performed in 6/10 (4 stent placement, 1 balloon angioplasty of pulmonary arteries and 1 revision of systemic to pulmonary shunt). Six of the nonresponders died.¶Conclusion: A trial of inhaled NO after cardiac surgery in neonates and infants may be useful to differentiate reversible pulmonary vasoconstriction from fixed anatomic obstruction and may provide useful information if temporary support with extracorporeal membrane oxygenation is considered. Failure to respond to inhaled NO should prompt further investigations to rule out a residual obstruction.

    Notes: Abstract Objectives: 1. To document the clinical course of paediatric beating heart organ donors. 2. To evaluate the effect of the ICU management of pediatric donors on the immediate function of transplanted organs. 3. To examine the validity of current donor selection criteria. Design: Retrospective chart review and case series study. Setting: Multidisciplinary ICU of tertiary referral paediatric hospital. Patients: All patients who became solid organ donors between January 1980 and July 1990. Outcome Measures: 1. Incidence of major physiological abnormalities of the cardiovascular, pulmonary, renal and metabolic systems. 2. Number of organs retrieved and transplanted, reasons for non-translantation of donated organs. 3. Immediate post-transplant function of transplanted organs. Results: Seventy-seven organ donors were identified from whom 134 kidneys, 31 livers and 12 hearts were transplanted. Sixty (78%) patients developed diabetes insipidus. Sustained hypotension occurred in 41 (53.2%) and was commoner in patients treated with inotropic agents in the presence of a low central venous pressure and in patients with diabetes insipidus who did not receive anti-diuretic hormone replacement. Twenty-seven patients suffered at least one cardiac arrest. The data on post-transplant function were obtained 28.8nfor 129 kidneys (from 70 donors) 30 livers and 9 hearts. Fifty-two kidneys, 10 livers and 2 hearts were transplanted from donors who had suffered at least one cardiac arrest without apparent adverse effect on post-transplant organ function. Thirty-six kidneys from 31 donors suffered either acute tubular necrosis (ATN) or primary non-function. The donors of these organs spent longer in ICU (60.6±45.7 h versus 41.8±30.1 h p=0.045) and had a higher mean maximum serum sodium concentration (163.4±10.9 versus 158.5±9.5 mmol/l p=0.05) than those without these complications. The serum creatinine concentration and degree of inotropic support did not predict post-transplant function. Standard biochemical tests for hepatic function, the dose of inotropic agent received, time in ICU and incidence of hypotension did not predict post-transplant liver function. Conclusions: Aggressive fluid resuscitation and management of diabetes insipidus may promote stability in paediatric organ donors. Donor cardiac arrest does not alter the ICU course or compromise post-transplant organ function. The current criteria used for donor selection failed to predict post-transplant organ function and their use may increase organ wastage.

    Notes: Abstract Objective To investigate the effect of single dose and continuous skeletal muscle paralysis on respiratory system compliance in 53 paediatric intensive care patients. Design Prospective clinical study. Setting Multidisciplinary paediatric intensive care unit. Patients Twenty-three children ventilated for acute pulmonary pathology, and 30 ventilated for isolated intracranial pathology, who initially had normal lungs. Interventions The 23 patients with acute pulmonary pathology received a single dose of muscle relaxant to facilitate diagnostic procedures. Fifteen patients with isolated intracranial pathology received continuous skeletal muscle paralysis for longer than 24 h, and the other 15 received no paralysis. Measurements and results Respiratory system complicance deteriorated by 14% from 0.519±0.2 to 0.445±0.18 ml cmH2O−1 kg−1 (p〈0.001) following a single dose of muscle relaxant in the 23 patients with acute pulmonary pathology. In the 15 with isolated intracranial pathology who received continuous skeletal muscle paralysis there was a progressive deterioration in compliance, which reached 50% of the initial compliance by day 4 of paralysis (p〈0.001) and improved back to normal following discontinuation of paralysis. There were no changes in compliance in the 15 patients with isolated intracranial pathology who were ventilated but not paralysed. The paralysed patients required mechanical ventilation longer than the non-paralysed patients (p〈0.001), and 265 of these patients developed nosocomial pneumonia (p=0.03), a complication that was not seen in the non-paralysed patients. Conclusions Skeletal muscle paralysis results in immediate and progressive deterioration of respiratory system compliance and increased incidence of nosocomial pneumonia. The benefits of paralysis should be balanced against the risks of deteriorating pulmonary function.

    Notes: Summary The effect of hypothermia on the disposition of fentanyl was evaluated in 18 children undergoing corrective cardiac surgery. They received a bolus of fentanyl followed by a continuous infusion which was stopped when cardiopulmonary bypass was established and profound hypothermia was achieved (18 °C–25 °C). Fentanyl plasma concentration remained essentially unchanged during hypothermia (6.45 ng/ml 5 min into hypothermia and 5.26 ng/ml 100–140 min later; p〉0.1). In subsequent experiments, the effect of hypothermia on the pharmacokinetics of fentanyl was studied in 4 piglets serving as their own controls. Both distribution volume (Vz) and total body clearance (CL) were significantly smaller during hypothermia. Our studies indicate that being a drug with a large distribution volume and a high hepatic extraction ratio, both CL and Vz are significantly reduced by hypothermia-induced hypoperfusion. In addition, TBC is influenced by the temperature-dependent hepatic metabolism of fentanyl.

    Notes: Nitric oxide is a potent endogenous vasodilator involved in the homeostatic control of systemic blood pressure. It has also recently been demonstrated that when inhaled in low concentrations it acts as a specific pulmonary vasodilator. The concept of inhaled nitric oxide as a form of therapy is almost an anathema to anaesthetists. However, nitric oxide is being used increasingly for the treatment of persistent pulmonary hypertension of the neonate and in the adult respiratory distress syndrome. One major limitation to its frequent and widespread use is the problem of measuring the concentration of nitric oxide delivered. Currently, the gold standard technique used is chemiluminesence. However, the equipment required is costly and can be difficult to use. If the use of inhaled nitric oxide increases and it develops a therapeutic role then its applications may be limited only to centres which can afford such equipment. Others may be prevented from using a potentially valuable therapy due to lack of a controlled delivery system for nitric oxide. An inexpensive, simple alternative technique to chemiluminesence is described, which will allow most intensive care units the freedom to use inhaled nitric oxide if necessary.

    Notes: Summary Intermittent right-posterior accentuated slow waves (irregular theta and/or delta waves: IRP phenomenon) in the EEG showed an incidence of about 5% in the total in-patients of a psychiatric university hospital. The IRP phenomenon was found in 7.5% of patients with schizophrenic psychoses, 2% of patients with affective psychoses and in 2.4% of patients with neurotic and personality disorders. The IRP groups differed from control groups in a number of sociobiographical and clinical characteristics. Having repeatedly confirmed these relationships with different samples, we regard IRP patients, irrespective of the diagnosis given, as having a maturational deficit of brain function.

    Notes: A rapid laboratory method for processing quality color prints of high resolution two-dimensional polyacrylamide gels has been developed to obtain photographs for data storage or for the presentation of results in poster formats. This method involves the contact printing of a gel directly onto the film so that the final print will be an exact duplication of the size and color of the gel. A variety of papers or films can be used to produce color prints or transparencies. This method has been adapted for use with a color or with a black and white photographic enlarger.
