Comparison of Multiple Injection Costotransverse Block and Erector Spinae Plane Block for Post-Sternotomy Pain Relief in Pediatric Patients Undergoing Cardiac Surgery: A Prospective Randomized Comparative Study.

OBJECTIVE: The aim of this study was to evaluate the efficacy of ultrasound-guided multiple injection costotransverse block (MICB) and compare it with erector spinae plane block (ESPB) for poststernotomy pain relief in pediatric cardiac surgical patients. DESIGN: A prospective, randomized, double-blind, comparative study. SETTING: At a single institution tertiary referral cardiac center. PARTICIPANTS: A total of 90 children with acyanotic congenital heart disease requiring surgery via sternotomy. INTERVENTIONS: Children were allocated randomly to 1 of the 3 following groups: ESPB (group 1), MICB (group 2), or Control (group 3). Participants in groups 1 and 2 received 4 mg/kg of 0.2% ropivacaine for bilateral ultrasound-guided block after induction of anesthesia. Postoperatively, intravenous paracetamol was used for multimodal analgesia, and fentanyl/tramadol was used for rescue analgesia. MEASUREMENTS AND MAIN RESULTS: The modified objective pain score (MOPS) was evaluated at 0, 1, 2, 4, 6, 8, 10, and 12 hours postextubation. After all exclusions, 84 patients were analyzed. The MOPS score was found to be significantly lower in ESPB and MICB groups compared to the control group until 10 hours postextubation (p < 0.05), with no statistically significant difference at the 12th hour (p = 0.2198). The total intraoperative fentanyl consumption (p = 0.0005), need for fentanyl supplementation on incision (p < 0.0001), and need for rescue opioid requirement in the postoperative period (p = 0.034) were significantly lower in both the ESPB and MICB groups than the control group. There were no statistically significant differences in both primary and secondary outcomes between the ESPB and MICB groups. CONCLUSION: Ultrasound-guided MICB was effective and comparable to ESPB for post-sternotomy pain management in pediatric cardiac surgical patients.

Comparison of Changes in Thoracic Fluid Content Between On-Pump and Off-Pump CABG by Use of Electrical Cardiometry.

OBJECTIVES: To compare the changes in thoracic fluid content, PaO2/FIO2 ratio, plateau pressure, compliance, and postoperative ventilation duration in off-pump coronary artery bypass grafting (OPCAB) and on-pump coronary artery bypass grafting (ONCAB). DESIGN: Prospective observational study. SETTING: Tertiary-care cardiac center. PARTICIPANTS: Over an 18-month period, from December 2019 to May 2021, 111 patients who underwent CAB grafting were enrolled. Group I constituted OPCAB patients and Group II the ONCAB patients. INTERVENTIONS: After induction, the authors measured thoracic fluid content (TFC), pulmonary compliance, airway pressures, and the PaO2/FIO2 ratio before skin incision (T1) and after skin closure (T2). The input, output, as well as the duration of postoperative ventilation, also were recorded. RESULTS: At T2, the ONCAB group had a significantly higher change in TFC than the OPCAB group (5.4 ± 1.86 kOhm-1v 4.32 ± 1.84 kOhm-1, p = 0.012). The fluid balance was significantly higher in the OPCAB group compared with the ONCAB group (2,159.21 ± 108.73 mL v 1,792.50 ± 151.88 mL, p = 0.0001). The decrease in PaO2/FIO2 ratio was significantly lower in the OPCAB group compared with the ONCAB group (-71.34 ± 23.42 v -123.65 ± 36.81, p = 0.000). The increase in plateau pressure, decrease in compliance, and postoperative ventilation period were significantly higher in the patients who underwent ONCAB than the patients who underwent OPCAB (p < 0.05). CONCLUSION: The change in TFC was greater in the ONCAB group, despite the fact that the fluid balance was higher in the OPCAB group. A higher TFC in ONCAB led to lower PaO2/FIO2 ratio, lower compliance, higher plateau pressures, and longer postoperative ventilation.

A Retrospective Analysis of Clinical Manifestations, Management and Outcome of Acute Respiratory Distress Syndrome Associated with Coronavirus Disease-2019 Infection in Children.

Background: Acute respiratory distress syndrome (ARDS) associated with COVID-19 in children is not well described in the literature, so this study was designed to assess the severity, clinical course, different treatment measures, and outcome of this group of patients. Patients and methods: This descriptive study was performed by retrospective chart review of children admitted in pediatric intensive care unit (PICU) in the age-group of 1 month to 12 years over the period of 6 months (July-December 2020) in a tertiary care pediatric COVID facility in eastern India. Severity of ARDS, ventilator settings, oxygenation and laboratory parameters, and outcomes were documented. Predictors associated with severe ARDS were evaluated. Results: Among 128 laboratory-confirmed pediatric COVID-19 cases admitted in PICU, 18 (14%) developed ARDS, 6 (33.3%) had severe ARDS, and 3 (16.6%) succumbed to death. Outcome was measured by median hospital stay [20 days (IQR 19, 21)], PICU stay [13 days (IQR 10, 16)], and 28-day ventilator-free days [14 days (IQR 13, 22)]. Half (n = 9) of our study cohort had different comorbidities and congenital heart disease being the most common (4, 22.2%). Median positive end-expiratory pressure requirement was 10 cm H2O (9, 11) for invasively ventilated children (n = 13, 72.2%) along with peak inspiratory pressure of 24 cm H2O (20, 29) and mean airway pressure of 17 cm H2O (14, 20). Median oxygenation index was 13.3 (10.5, 18.6). Nine (69.2%) out of 13 intubated children had undergone prone ventilation. C-reactive protein (CRP) and D-dimer levels were significantly high in children with severe ARDS alongside pSOFA and lung USG score. Conclusion: Incidence of ARDS in pediatric COVID-19 though less but is not rare. Elevated CRP, D-dimer values, and high lung USG scores were associated with severe ARDS. Those who died had significant comorbidity. How to cite this article: Sarkar M, Das B, Mahapatra MK, Roychowdhoury S, Das S, Konar MC.

Unforeseen rupture of pseudoaneurysm of common carotid artery: An arduous anesthetic challenge.

Pseudoaneurysm of the common carotid artery (CCA) is exceptionally unstable and unpredictable; it mandates quick medical attention in order to circumvent neurologic sequelae or hemorrhage. Unanticipated rupture is extremely lethal and a potential provocation for the anesthesia caregiver. It is an arduous challenge for an anesthetist to establish emergency airway when a huge bleeding pseudoaneurysm is compressing and deviating the trachea, securing invasive lines in collapsing vessels, volume and vasopressor resuscitation in deteriorating hemodynamics in order to maintain cerebral perfusion without compromising other vital organs, arranging huge amount of blood and blood products in a short span of time, and transferring an exsanguinating patient for the rapid institution of cardiopulmonary bypass. Not only preoperatively it also necessitates appropriate neuromonitoring and neuroprotection during and after surgery. The association of unforeseen rupture of common carotid artery pseudoaneurysm secondary to the tubercular spine and lifesaving management by the rapid institution of cardiopulmonary bypass (CPB) is a rare occasion. To the best of the authors' knowledge, there is not any similar case in the peer-reviewed literature. Therefore, the authors enumerate the clinical experience of an unexpected rupture of CCA pseudoaneurysm requiring lifesaving CPB and emphasize the "Timely Teamed Effort Approach" that can sustain a life in such an inevitable situation.

Effect of change in tidal volume on left to right shunt across ventricular septal defect in children - A pilot study.

BACKGROUND: Pulmonary vascular resistance, an important determinant of shunting across ventricular septal defects (VSD), rises at both extremes of lung volume. AIMS: We sought to determine the effect of changes in tidal volumes (VT) on pulmonary blood flow (Qp), systemic blood flow (Qs), and shunt (Qp/Qs) in children with VSD. SETTING: Single-center teaching hospital. DESIGN: Prospective observational study. METHODS: Thirty children with a mean age of 11.8 ± 5 months undergoing surgical closure of VSD were studied. Hemodynamics and shunt-related parameters were assessed using transthoracic echocardiography measured at three different VT i.e. 10, 8, and 6-ml/kg keeping the minute ventilation constant. RESULTS: Reduction in VT from 10 to 8 to 6 ml/kg led to a reduction in gradient across VSD measuring 23.5, 20 and 13 mmHg respectively (P < 0.001). Similarly, right ventricluar outflow tract (RVOT) diameter, RVOT velocity time integral, Qp (57.3 ± 18.1, 50.6 ± 16.9, 39.9 ± 14.7 mL; P < 0.001), Qs (24.1 ± 10.4, 20.0 ± 8.7, 15.3 ± 6.9 mL; P < 0.001) and peak airway pressure (17.2 ± 1.5, 15.8 ± 1.3, 14.5 ± 1.2 cmHg; P < 0.001) showed progressive decline with decreasing VT from 10 to 8 to 6 ml/kg, respectively. However, Qp/Qs (2.4 ± 0.4, 2.6 ± 0.4, 2.6 ± 0.4) demonstrated a minor increasing trend. CONCLUSION: Lower VT reduces the gradient across VSD, the pulmonary blood flow, and the peak airway pressure. Hence, ventilation with lower VT and higher respiratory rate maintaining adequate minute ventilation might be preferable in children with VSD. Further studies are required to confirm the findings of this pilot study.

Feasibility and Utility of Adenosine Stress Echocardiography in Children Following Post-Arterial Switch Operation: A Comparison with Technetium 99m-Sestamibi Myocardial Perfusion SPECT (MPS).

There is a need for a sensitive, safe, and cost-effective tool for coronary assessment among asymptomatic post-operative children who have undergone arterial switch operation (ASO) for transposition of great arteries (TGA). Adenosine stress echocardiography may be useful in assessing major structures as well for coronary functional assessment. Twenty-six children [median age 6.0 years; IQR 4.9-7.1 years, (22 boys)], who had undergone ASO at a median age of 40 days (IQR 30-75 days), were prospectively included. Left ventricular ejection fraction (LVEF) was calculated in both rest and stress studies (140 µg/kg/min of adenosine IV over 4 min), along with assessment of regional myocardial wall motion. Coronary flow reserve (CFR) was also measured in the left anterior descending artery (LAD). Technetium 99m-MIBI [0.2mCi/kg] was injected after 2 min of adenosine infusion. Adenosine infusion had to be stopped in two children, due to transient atrioventricular (AV) block. The LVEF increased from 55.87 ± 7.27 to 61.20 ± 7.70% (p < 0.001) with adenosine stress. No significant regional wall motion abnormality was seen in rest or stress. Distal LAD could not be visualized in four patients. Basal and peak coronary flow velocities were 41.51 ± 14.12 and 74.18 ± 6.01 cm/s. Mean CFR was 1.91 ± 0.51. Myocardial perfusion scintigraphy (MPS) was normal in all the patients. Four patients were lost to follow-up and remaining children did not develop any adverse events in the follow-up period of 64.5 ± 7.19 months. Adenosine stress echocardiography is feasible as the initial screening test in the assessment of asymptomatic post-operative children with ASO, at minimal to no inconvenience to the patient. The findings concurred with stress MPS.

Comparison of pleural effusion between fenestrated and nonfenestrated extracardiac Fontan: A prospective randomized study.

BACKGROUND: Fenestration of the baffle/conduit is believed to reduce pleural effusion following the Fontan operation. However, equivocal results have been observed with or without fenestration. This study aims to evaluate the efficacy of fenestration on the amount and duration of pleural effusion following the Fontan operation. METHODS: About 40 patients undergoing extracardiac Fontan (ECF) were randomized into two groups: one with fenestration (ECF-F; n = 20) or without fenestration (ECF-NF; n = 20). Primary outcome was the amount and duration of pleural effusions. Secondary outcomes were time to removal of the chest tubes, hospital stay, and readmission to the hospital because of recurrent pleural within 30 days of the operation. RESULTS: Mean age was 11.5 ± 5.07 (range, 8.7-13.5) years in the ECF-F group and 13.6 ± 0.4 years (range, 10.5-15.5) in the (ECF-NF) group. The total drain output was 7.89 mL/kg/d in ECF-NF compared with 6.9 mL/kg/d in the ECF-group (P = .14). Time for removal of pleural tubes was 14.6 ± 0.95 days in the ECF-NF group compared with 11.6 ± days in the ECF-F group. Total duration of hospital stay was higher but not significant in the ECF-NF group compared with the ECF-F group. Two patients in ECF-NF required readmission to the hospital within 30 days following discharge, while there were no readmissions in the ECF-F group. CONCLUSION: Contrary to the literature, the creation of a fenestration in the ECF circuit was not clearly associated with a reduction in the amount and duration of pleural effusion compared with a non-fenestrated Fontan. These findings may be debatable in high risks versus low risk candidates. However in the present study, in a low risk canditates undergoing the Fontan operation, the daily amount of pleural drainage was no different. Larger studies are needed to confirm these findings.

Novel mutation detection in craniosynostosis promotes characterization, identification, gene expression, tissue engineering and helps clinical practice and translational research.

INTRODUCTION: Craniosynostosis (CS) syndrome is an autosomal dominant condition (ADC) classically combining with CS and nonsyndromic CS (NSCS) including digital anomalies of the hands and feet. The majority of cases caused by a heterozygous mutation (HM) in the third immunoglobulin-like domain (IgIII) of fibroblast growth factor receptor (FGFR) 2 mutations outside this region of the protein. MATERIAL AND METHODS: We tried to find out the spectrum of genes involved in CS syndrome caused by the heterozygous missense mutation, the IgII and IgIII of FGFR2. FGFR3, FGFR4, TWIST, and MSX genes were performed and verified through the Indian population with CS children. RESULTS: We find out that at conserved linker region (LR), the changes occurred among the larger families. Independent genetic origins, but phenotypic similarities add to the evidence supporting the theory of selfish spermatogonial selective advantage for this rare gain-of-function FGFR2 mutation. Polygenic novel mutation in both syndromic and nonsyndromic cases of CS promotes the translational research and holds a great promise to reproduce the molecular-based therapy and treatment as well. In this article, we summarized that genes involved in CS as evidence-based approach for characterization, identification, gene expression, and tissue engineering. We also described other related genes and proteins for the CS involvement and improvement of the diseases progression. CONCLUSION: HM again repeated the old story for both groups of syndromic CS and NSCS of Asian Indian children. Here, for the first time, we clearly reported that IgIII of FGFR2 mutations outside this region of the protein and tyrosine kinase (TK1 and TK2) responsible for both in molecular and cellular level for CS. It adds an evidence for future molecular targeting therapy to repair CS.

Left ventricular outflow tract obstruction following aortic valve replacement: A review of risk factors, mechanism, and management.

The presence of dynamic left ventricular outflow tract obstruction (LVOTO) can complicate the postoperative course of patients undergoing surgical aortic valve replacement (AVR). The phenomenon of LVOTO is a consequence of an interplay of various pathoanatomic mechanisms. The prevailing cardiovascular milieu dictates the hemodynamic significance of the resultant LVOTO in addition to the anatomical risk factors. A thorough understanding of the predisposing factors, mechanism, and hemodynamic sequel of the obstruction is pivotal in managing these cases. A comprehensive echocardiographic examination aids in risk prediction, diagnosis, severity characterization, and follow-up of management efficacy in the setting of postoperative LVOTO. The armamentarium of management modalities includes conservative (medical) and surgical options. A stepwise approach should be formulated based on the physiological and anatomical substrates predisposing to LVOTO. The index phenomenon occurs more frequently than appreciated and should be considered when the post-AVR patients exhibit hemodynamic instability unresponsive to conventional supportive measures. The present article provides an overview of various peculiarities of this under-recognized phenomenon in the context of the perioperative management of patients undergoing AVR.

Perioperative Anxiety and Stress in Children Undergoing Congenital Cardiac Surgery and Their Parents: Effect of Brief Intervention-A Randomized Control Trial.

OBJECTIVE: To know the effects of psychological preparation on perioperative stress, anxiety, and mood in children undergoing cardiac surgery and their parents. DESIGN: Prospective randomized control nonblinded trial. SETTING: Single-center tertiary teaching hospital. PARTICIPANTS: A total of 60 children aged 5 to 15 years undergoing cardiac surgery were included in the study. One of the parents, preferably the father, was selected from the respective children. INTERVENTIONS: Subjects were randomized into 2 groups: noninterventional (group 1) and interventional (group 2). Intervention was in the form of toys and video games in children, and counseling and information in parents. Preoperative and postoperative anxiety in parents was measured using the State-Trait Anxiety Inventory (STAI), stress using the Index of Clinical Stress (ICS) scale by Abell, and the Ottawa mood scale. In children, the STAI-C (child version of STAI), Ottawa mood and Ottawa stress scales, and Wong-Baker faces pain scale were applied and serum cortisol was measured. MEASUREMENTS AND MAIN RESULTS: Group 2 children had significantly less (p < 0.001) stress, anxiety, and pain and improved mood. Group 2 parents had a significant reduction in state anxiety (42 ± 4.4 v 54.5 ± 7.8; p < 0.001) and ICS score (68.1±9.6 v 84.2 ± 9.2; p < 0.001) and an improvement in mood (7.5 ± 0.7 v 5.9 ± 1; p < 0.001) compared with group 1. Postoperatively, cortisol levels in group 2 were lower than group 1 (571.3 nmol/L [123.3 -1247.14] v 718.9 nmol/L [53-1642.0]). CONCLUSION: Providing video games and toys preoperatively reduced postoperative stress and anxiety and improved mood in children undergoing congenital cardiac surgery. Parents were relieved of anxiety and stress with proper counseling and information.

Effect of goal-directed therapy on post-operative neutrophil gelatinase-associated lipocalin profile in patients undergoing on-pump coronary artery surgery.

PURPOSE: Neutrophil gelatinase-associated lipocalin (NGAL) is an early biomarker of acute kidney injury (AKI). Goal-directed therapy (GDT) in on-pump coronary artery bypass grafting (CABG) has been associated with lower post-operative NGAL levels in recent studies. The present study aimed at comparing plasma (P) and urinary (U)-NGAL levels following the use of GDT versus conventional haemodynamic therapy (CT) in patients undergoing on-pump CABG. METHODS: A prospective randomised controlled study conducted in a single university hospital. A total of 54 patients in the GDT group and 56 patients in CT group after exclusions. RESULTS: U-NGAL was significantly lower immediately post-surgery (T 1) in GDT group (25.11 ± 1.5 versus 27.80 ± 1.7 µg/L; p < 0.001) and at 4 h (T 2) (38.19 ± 23.6 versus 52.30 ± 28.3 µg/L; p = 0.006) and at 24 h post-operatively (T 3) (34.85 ± 14 versus 39.7 ± 11.1 µg/L; p = 0.047). P-NGAL was comparable between groups at T 1 but lower in the GDT group at T 2 (92.81 ± 4.8 versus 94.77 ± 4.5 µg/L; p = 0.03) and T 3 (67.44 ± 3.7 versus 75.96 ± 5.3 µg/L; p < 0.001). U-NGAL levels correlated well with the peak post-operative creatinine as compared to P-NGAL. On-pump patients manifest neutrophil activation, accounting for comparable levels of P-NGAL in the two groups at T 1. GDT-based haemodynamic management resulted in lower U-NGAL levels at T 1, T 2 and T 3 and lower P-NGAL levels at T 2 and T 3. CONCLUSIONS: Haemodynamic optimisation with GDT prevents further renal insult initiated with the inflammatory activation with cardiopulmonary bypass (CPB), as evidenced by lower post-operative U-NGAL levels.

Genome-Wide Association Study in Craniosynostosis Condition Using Innovative Systematic Bioinformatic Analysis Tools and Techniques: Future Prospective and Clinical Practice.

BACKGROUND: Craniosynostosis (CS) conditions are included with the premature fusion of one or more multiple cranial sutures. As the second leading and most common craniofacial anomaly and orofacial clefts globally. Syndromic and nonsyndromic CS (NSCS) occur as a part of a genetic syndrome unlike Apert, Crouzon, Pfeiffer, Muenke, and Saethre-Chotzen syndromes. Approximately, 90% of the cases of CS arises from NSCS group and it is now a great challenge for the researcher and neurosurgeon for Indian-origin children, a great burden worldwide. MATERIAL AND METHODS: Study design: Prospective study of analysis sequence pattern on CS and NSCS from January 2007 to 2018 was carried out.Inclusion criteria: Diagnosed cases in syndromic and NSCS patients between 3 months and 14 years of age either preoperative or postoperative were included in the study of both groups (syndromic and NSCS).Exclusion criteria: Patients with primary microcephaly (secondary CS), postural plagiocephaly, incomplete data, no visual perception, and who were lost to follow-up, and who had no interest to participate the study were excluded from the study.Bioinformatic analysis: We have performed systematic bioinformatic analysis for all responsible genes by combining with using through the GeneDecks, Gene Runner, DAVID, and STRING databases.Genes testing: FGF family genes, MSX genes, such as Irf6, TP63, Dlx2, Dlx5, Pax3, Pax9, Bmp4, Tgf-beta2, and Tgf-beta3 were found to be involved in Cleft lip and cleft palate (CL/P), and Fgfr2, Fgfr1, Fgfr3, and TWIST, MSX, MSX1, 2 were found to be involved in both the groups of CS (SCS + NSCS). RESULTS: FGFR, MSX, Irf6, TP63, Dlx2, Dlx5, Pax3, Pax9, Bmp4, Tgf-beta2, and Tgf-beta3 demonstrated and find out that in CL/P, and Fgfr2, Fgfr1, Fgfr3, and Twist1 had accurate sequence data with more than accuracy of 95% reported with proper order with additional anomalies CS through newly developed tools. CONCLUSION: Newly developed techniques of GeneDecks, Gene Runner, DAVID, and STRING databases gave better picture to analyze the larger population, patients (SCS + NSCS) with complex genetic, maternal, parental age, environmental, and stochastic factors contributing to NSCS networking, signaling, and pathways involvement. This bioinformatic tools analyzed better prediction of CS and NSCS sequences guiding us the newer invention modalities of pattern of screening and further development of recent future application.

The role of Rajyoga meditation for modulation of anxiety and serum cortisol in patients undergoing coronary artery bypass surgery: A prospective randomized control study.

INTRODUCTION: Rajyoga meditation is a form of mind body intervention that is promoted by the Brahma Kumaris World Spiritual University. This form of meditation can be easily performed without rituals or mantras and can be practiced anywhere at any time. The practice of Rajyoga meditation can have beneficial effects on modulating anxiety and cortisol level in patients undergoing major cardiac surgery. MATERIALS AND METHODS: A prospective randomized control study was carried out in a single tertiary care center. One hundred and fifty patients undergoing elective coronary artery bypass surgery were enrolled in the study. The patients were randomized in two groups namely, Group 1 (Rajyoga group) and Group 2 (Control Group). Anxiety was measured on a visual analog scale 1-10 before the start of Rajyoga training or patient counseling (T1), on the morning of the day of surgery (T2), on the 2nd postoperative day (T3), and on the 5th postoperative day (T4). The serum cortisol level was measured in the morning of the day of surgery (T1), on the 2nd postoperative day (T2) and on the 5th postoperative day (T3), respectively. RESULTS: In the study, it was seen that the anxiety level of the patients before the surgery (T1) and on the day of surgery (T2) were comparable between the two groups. However on the 2nd postoperative day (T3), the patients who underwent Rajyoga training had lower anxiety level in comparison to the control group (3.12 ± 1.45 vs. 6.12 ± 0.14, P < 0.05) and on the 5th postoperative day (T4) it was seen that Rajyoga practice had resulted in significant decline in anxiety level (0.69 ± 1.1 vs. 5.6 ± 1.38, P < 0.05). The serum cortisol level was also favorably modulated by the practice of Rajyoga meditation. CONCLUSION: Mindbody intervention is found to effective in reducing the anxiety of the patients and modulating the cortisol level in patients undergoing wellknown stressful surgery like coronary artery bypass surgery.

Effect of preoperative statin therapy on early postoperative memory impairment after off-pump coronary artery bypass surgery.

CONTEXT: Frequent incidence of early postoperative memory impairment (POMI) after cardiac surgery remains a concern because of associated morbidity, impaired quality of life, and increased health care cost. AIM: To assess the effect of preoperative statin therapy on POMI in patients undergoing off-pump coronary artery bypass (OPCAB) surgery. SETTING AND DESIGN: Prospective observational study in a tertiary level hospital. METHODS: Sixty patients aged 45-65 years undergoing OPCAB surgery were allocated into two groups of 30 each. Group A patients were receiving statin and Group B patients were not receiving statins. All patients underwent memory function assessment preoperatively after admission to hospital and on the 6 th postoperative day using postgraduate institute memory scale. STATISTICAL ANALYSIS: Appropriate tests were applied with SPSS 20 to compare both groups. The value P < 0.05 was considered statistically significant. Multiple regression analysis was performed with confounding factors to determine the effect on memory impairment. RESULTS: Patients in Group A showed significant postoperative deterioration in 6 of the 10 functions and in Group B showed deterioration in 9 of 10 functions tested compared to preoperative scores. Intergroup comparison detected less POMI in Group A compared to Group B and was statistically significant in 8 memory functions. Multiple regression analysis detected statin as an independent factor in preventing memory impairment. CONCLUSIONS: Preoperative statin therapy attenuates the early POMI in patients undergoing OPCAB. Future long-term studies will define the efficacy of statin on POMI.

Novel mutation detection of fibroblast growth factor receptor 1 (FGFR1) gene, FGFR2IIIa, FGFR2IIIb, FGFR2IIIc, FGFR3, FGFR4 gene for craniosynostosis: A prospective study in Asian Indian patient.

BACKGROUND: Craniosynostosis (CS) syndrome is an autosomal dominant condition classically combining craniosynostosis and non-syndromic craniosynostosis with digital anomalies of the hands and feet. The majority of cases are caused by heterozygous mutations in the third immunoglobulin-like domain (IgIII) of FGFR2, whilst a larger number of cases can be attributed to mutations outside this region of the protein. AIMS: To find out the FGFR1, FGFR2, FGFR3 and FGFR4 gene in craniosynostosis syndrome. SETTINGS AND DESIGN: A hospital based prospective study. MATERIALS AND METHODS: Prospective analysis of clinical records of patients registered in CS clinic from December 2007 to January 2015 was done in patients between 4 months to 13 years of age. We have performed genetic findings in a three generation Indian family with Craniosynostosis syndrome. RESULTS: We report for the first time the clinical and genetic findings in a three generation Indian family with Craniosynostosis syndrome caused by a heterozygous missense mutation, Thr 392 Thr and ser 311 try, located in the IgII domain of FGFR2. FGFR 3 and 4 gene basis syndrome was eponymously named. Genetic analysis demonstrated that 51/56 families to be unrelated. In FGFR3 gene 10/TM location of 1172 the nucleotide changes C>A, Ala 391 Glu 19/56 and Exon-19, 5q35.2 at conserved linker region the changes occurred pro 246 Arg in 25/56 families. CONCLUSIONS: Independent genetic origins, but phenotypic similarities in the 51 families add to the evidence supporting the theory of selfish spermatogonial selective advantage for this rare gain-of-function FGFR2 mutation.

Unruptured Sinus of Valsalva Aneurysm with Right Ventricular Outflow Tract Obstruction and Ventricular Septal Defect--A Rare Combination.

Sinus of Valsalva aneurysms are rare cardiac anomalies that may be acquired or congenital. We describe the case of a patient who had an unruptured sinus of Valsalva aneurysm causing right ventricular outflow obstruction, with an associated subaortic ventricular septal defect. Sinus of Valsalva aneurysms rarely present until rupture occurs. However, the unruptured aneurysm of the right sinus of Valsalva caused significant right ventricular outflow tract obstruction, resulting in exertional dyspnea. Intraoperative multiplane transesophageal echocardiography and color Doppler helped in precise identification of structural anomalies, shunt location, and definitive surgical repair.

Double aortic arch as a source of airway obstruction in a child.

Double aortic arch (DAA) is a congenital vascular anomaly. The diagnosis was difficult till the child was symptomatic, and other causes were ruled out. We present the interesting images of a child of respiratory distress because of tracheal compression from DAA.

Efficacy of dexmedetomidine for the control of junctional ectopic tachycardia after repair of tetralogy of Fallot.

BACKGROUND: Junctional ectopic tachycardia occurs frequently after congenital cardiac surgery and can be a cause of increased morbidity and mortality. Dexmedetomidine (DEX) is an α2 adrenoreceptor agonist, has properties of controlling tachyarrhythmia by regulating the sympatho-adrenal system. OBJECTIVE: To evaluate the efficacy of DEX for control of junctional ectopic tachycardia after repair of Tetralogy of Fallot (TOF). MATERIALS AND METHODS: Two hundred and twenty pediatric cardiac patients with TOFs were enrolled in a prospective randomized control study. Patients underwent correction surgery. They were divided into two groups, i.e., Group 1 (DEX) and Group 2 (control). Heart rate, rhythm, mean arterial pressure (MAP) were recorded after the anesthetic induction (T1), after termination of bypass (T2), after 04 hours (T3), and 08 hours after transferring the patient to intensive care unit (ICU; T4). RESULTS: Heart rate was comparable between two groups before starting the drug but statistically significant after bypass until 08 hours after transferring the patient to ICU. Junctional ectopic tachycardia occurred more in Group-2 (20%) as compared to Group-1 (9.09%; P = 0.022). Junctional ectopic tachycardia occurs early in Group-2 (0.14 ± 0.527 hours) as compared to Group 1 (0.31 ± 1.29 hours; P = 0.042). The duration of junctional ectopic tachycardia was more prolonged in Group-2 (1.63 ± 3.64 hours) as compared to Group-1 (0.382 ± 1.60 hours; P = 0.012). The time to withdraw from mechanical ventilation and ICU stay of Group 1 patient was less than of Group 2 patients (P = <0.001). CONCLUSION: DEX had a therapeutic role in the prevention of junctional ectopic tachycardia in patients undergoing repair for TOF.
