RESUMEN

We hereby report a child with transposition of great arteries and regressed ventricle who underwent arterial switch operation (ASO) with the aid of cardiopulmonary bypass and “integrated” extracorporeal membrane oxygenation (ECMO) circuit. The significance of lactate clearance as a guide to initiate and terminate veno-arterial ECMO in a post ASO child with regressed left ventricle is discussed.

RESUMEN

Objective(s): This study aimed to determine the prevalence of carotid artery stenosis (CAS) due to atherosclerosis in neurologically asymptomatic patients undergoing coronary artery bypass grafting (CABG) for coronary artery disease (CAD). It contemplated a greater role for the cardiac anesthesiologist in the perioperative management of such patients with either previously undiagnosed carotid artery disease or towards re-assessment of severity of CAS. Design: Prospective, observational clinical study. Setting: Operation room of a cardiac surgery centre of a tertiary teaching hospital. Participants: A hundred adult patients with New York Heart Association (NYHA) classification I to III presenting electively for CABG. Interventions: All patients included in this study were subjected to ultrasonic examination by means of acarotid doppler scan to access for presence of CAS just prior to induction of general anesthesia. Measurements and Main Results: Based on parameters measured using carotid doppler, the presence of CAS was defined using standard criteria. The prevalence of CAS was found to be as high as 38% amongst the patients included in our study. The risk factors for CAS were identified to be advanced age, history of smoking, diabetes mellitus, dyslipidaemia and presence of a carotid bruit. Conclusion: This study points towards the relatively wide prevalence of carotid artery disease in neurologically asymptomatic patients undergoing CABG for CAD in the elective setting. It highlights the need to routinely incorporate carotid ultrasonography in the armamentarium of the cardiac anesthesiologist as standard of care for all patients presenting for CABG.

RESUMEN

Severe persistent hypertension is seen infrequently in newborns and infants, but we came across two infants who developed severe paradoxical hypertension after successful coarctation repair. Treatment of systemic hypertension following repair of coarctation of the aorta is always challenging particularly in infants. Dexmedetomidine was used successfully as an adjunct to the established anti‑hypertensive drugs in the immediate postoperative period in our cases to treat postoperative paradoxical hypertension.

RESUMEN

Indications for extra corporeal membrane oxygenation (ECMO) after pediatric cardiac surgery have been increasing despite the absence of encouraging survival statistics. Modification of ECMO circuit led to the development of integrated ECMO cardiopulmonary bypass (CPB) circuit at the author's institute, for children undergoing repair of transposition of great arteries among other congenital heart diseases (CHD). In this report, they analyzed the outcome of children with CHD, undergoing surgical repair and administered ECMO support in the last 10 years. The outcome was analyzed with reference to the timing of intervention, use of integrated ECMO-CPB circuit, indication for ECMO support, duration of ECMO run and the underlying CHD. The results reveal a significantly improved survival rate with the use of integrated ECMO-CPB circuit and early time of intervention rather than using ECMO as a last resort in the management. The patients with reactive pulmonary artery hypertension respond favorably to ECMO support. In all scenarios, early intervention is the key to survival.

RESUMEN

Chest tube removal in the postcardiac surgical patients is a painful and distressful event. Fentanyl and sufentanil have not been used for pain control during chest tube removal in the postoperative period. We compared efficacy offentanyl and sufentanil in controlling pain due to chest tube removal. One hundred and forty one adult patients undergoing cardiac surgery were recruited in a prospective, randomized, double blind, placebo controlled study. Patients were randomized to receive either 2 microg/Kg fentanyl IV or 0.2 microg/Kg sufentanil IV or 2 ml isotonic normal saline, 10 min before removing chest tubes. Pain intensity was assessed by measuring visual analog scale pain score 10 minutes before removing chest tubes and 5 min and 20 min after removing chest tubes. Level of sedation, heart rate, arterial pressure, oxygen saturation, and respiratory rate were recorded by a blinded observer at the same time intervals. Mean pain intensity scores 10 minutes before removal of chest tubes infentanyl, sufentanil and control groups were 23.88+/-5.2, 25.10+/-5.39 and 23.64+/-6.10 respectively. The pain scores 5 minutes after chest tube removal were reduced to 20.11+/-6.9 (p<0.05) in the fentanyl group and 13.60+/-6.60 (p<0.05) in the sufentanil group, whereas in control group pain scores increased to 27.97+/-8.39 (p<O.05). The pain scores in sufentanil group were significantly lower compared with fentanyl or control group. Sedation scores remained low in all groups and patients remained alert and none of the patients showed any adverse effects of opioids. Heart rate, arterial pressure and respiratory rate had least variations in sufentanil group than fentanyl or control group.

RESUMEN

We have studied the efficacy of epsilon aminocaproic acid in reducing postoperative blood loss in infants and children with congenital cyanotic cardiac anomalies undergoing corrective operative procedures. This prospective study was carried out on 170 infants and children randomly divided into two equal groups. Group A acted as the control group and received normal saline as placebo while group B patients received epsilon aminocaproic acid (100 mg/kg body wt) intravenously slowly soon after anaesthetic induction followed by 100 mg/kg in the cardiopulmonary bypass pump at the time of starting of cardiopulmonary bypass and 100 mg/kg after weaning from bypass over a period of 3 h. In group A the time for sternal closure after separation from bypass and administration of protamine was 75.18 +/- 5.5 min and in group B 50.7 +/- 5.2, (P < 0.001). Blood loss at 24 h in group A was 42.6 +/- 6.9 ml/kg/24 h and in group B 23.7 +/- 5.8 ml/kg/24 h, (P < 0.001). The need for packed red cells in group A was 21.8 +/- 7.1 ml/kg/24 h and in group B 10.7 +/- 7.8 ml/kg/24 h, (P < 0.001). The need for platelet concentrate in group A was 22.0 +/- 6.7 ml/kg/24 h and group B 6.2 +/- 3.2 ml/kg/24 h, (P < 0.001). Fibrin degradation products (split) in group A was 8.2 +/- 0.8 micrograms/ml, and group B 3.8 +/- 1.3 micrograms/ml, (P < 0.001). Reexploration rate was also considerably reduced in group B, 5 of 85 (6%) compared to group A, 13 of 85 (15%), (P < 0.001). It was found that epsilon aminocaproic acid is effective in reducing postoperative blood loss, packed red cells and plasma product requirements in paediatric patients undergoing corrective surgical procedures for congenital cyanotic heart diseases.
