Recurrence-free survival after curative resection of non-small cell lung cancer between inhalational gas anesthesia and propofol-based total intravenous anesthesia: a multicenter, randomized, clinical trial (GAS TIVA trial): protocol description.

Background: Surgery is the primary treatment for non-small cell lung cancer (NSCLC), but microscopic residual disease may be unavoidable. Preclinical studies have shown that volatile anesthetics might suppress host immunity and promote a pro-malignant environment that supports cancer cell proliferation, migration, and angiogenesis, whereas propofol may preserve cell-mediated immunity and inhibit tumor angiogenesis. However, clinical evidence that propofol-based total intravenous anesthesia (TIVA) can reduce tumor recurrence after curative resection remains inconsistent due to the retrospective observational nature of previous studies.

Delineating thrombus versus myxoma: Perioperative 3D transesophageal echocardiography to the rescue!

Cardiac masses are a significant cause of patient morbidity and mortality by virtue of their symptoms and surgical removal. Preoperative diagnosis of a cardiac mass is usually based on clinical correlation and transthoracic echocardiography findings. Myxomas are the most common benign cardiac tumors, commonly occurring in the left atrium attached to the interatrial septum near the fossa ovalis.

A randomized comparative evaluation of C-MAC video-laryngoscope with Miller laryngoscope for neonatal endotracheal intubation.

Background And Aims: An efficient neonatal airway management is peculiarly challenging even in the most experienced hands. Considering the recent interest in assessing the performance of various video-laryngoscopes (VL) in pediatric cohort, the prospective randomized study was contemplated to stage a comparative evaluation of C-MAC with Miller laryngoscope for neonatal endotracheal intubation.

Material And Methods: 150 neonates were randomized to undergo intubation with either the C-MAC VL ( = 75) or the Miller laryngoscope ( = 75) performed by an experienced anesthesiologist in a tertiary care perioperative setting.

Plasmalyte-A Based del Nido Cardioplegia Versus Plain Ringer Based del Nido Cardioplegia: Double-Blind Randomized Trial.

In this prospective randomized controlled trial, we compared the standard del Nido cardioplegia solution (SDN) with the modified del Nido cardioplegia solution (MDN) in which the base solution was the plain Ringer solution. A total of 80 patients aged < 12 years undergoing intracardiac repair of Tetralogy of Fallot were randomized into SDN (n = 39) or MDN (n = 41) groups. The primary outcome was a change in cardiac index (CI).

Patient blood management in India - Review of current practices and feasibility of applying appropriate standard of care guidelines. A position paper by an interdisciplinary expert group.

In a developing country like India, with limited resources and access to healthcare facilities, dealing with massive hemorrhage is a major challenge. This challenge gets compounded by pre-existing anemia, hemostatic disorders, and logistic issues of timely transfer of such patients from peripheral hospitals to centers with adequate resources and management expertise. Despite the awareness amongst healthcare providers regarding management modalities of bleeding patients, no uniform Patient Blood Management (PBM) or perioperative bleeding management protocols have been implemented in India, yet.

Renal Replacement Therapy Practices in India: A Nationwide Survey.

Introduction: Renal replacement therapy (RRT) is utilized for patients admitted with acute kidney injury and is becoming indispensable for the treatment of critically ill patients. In low middle income and developing country like India, the epidemiological date about the practices of RRT in various hospitals setups in India are lacking. Renal replacement therapy although is being widely practiced in India, however, is not uniform or standardized.

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.

Structural similarity, characterization of Poly Ethylene Glycol linkage and identification of product related variants in biosimilar pegfilgrastim.

The approval of biosimilars requires demonstration of biosimilarity, which rests on the base of thorough analytical characterization of the biosimilar product. In addition to demonstration of biosimilarity, the product related impurities need to be thoroughly characterized and controlled at minimal levels. Pegylation of peptides and proteins creates significant challenges for detailed structural characterization, such as PEG (Poly Ethylene Glycol) heterogeneity, site of addition and number of attached pegylated moieties.

Comparison of del Nido and histidine-tryptophan-ketoglutarate cardioplegia solutions in pediatric patients undergoing open heart surgery: A prospective randomized clinical trial.

Objectives: We conducted a prospective randomized controlled trial to compare del Nido (DN) and histidine-tryptophan-ketoglutarate (HTK) cardioplegia solution in pediatric patients undergoing intracardiac tetralogy of Fallot repair.

Methods: One hundred consecutive patients 12 years of age or younger, undergoing intracardiac repair of tetralogy of Fallot were randomized into DN (n = 50) and HTK (n = 50) groups. Cardioplegia strategy consisted of a single dose of DN (20 mL/kg) or HTK (6 mL/kg/min for 6 minutes).

Successful surgical osteoplasty of the left main coronary artery with concomitant mitral valve replacement and tricuspid annuloplasty.

A 50-year-old woman with rheumatic heart disease, mitral stenosis, and critical isolated left main ostial stenosis was successfully treated by mitral valve replacement, tricuspid annuloplasty, and surgery of left main osteoplasty and is reported for its rarity. Notable clinical findings included an intermittently irregular pulse, blood pressure of 100/70 mmHg, cardiomegaly, a diastolic precordial thrill, a mid-diastolic murmur without presystolic accentuation that was loudest at the mitral area. Chest radiograph revealed cardiomegaly with a cardiothoracic ratio of 0.

Pulmonary valve reconstruction during conduit revision: Technique and transesophageal echocardiography imaging.

Transesophageal echocardiography can be a useful adjunct in assessing the quality of repair in patients undergoing novel methods of reconstruction of the right ventricular outflow. We present one such patient here.

Relationship between perioperative left atrial appendage doppler velocity estimates and new-onset atrial fibrillation in patients undergoing coronary artery bypass graft surgery with cardiopulmonary bypass.

Background: Literature search reveals that postoperative atrial fibrillation (POAF) occurs in 15%-40% of coronary artery bypass graft (CABG) patients. Although several risk models exist for predicting the development of POAF, few have studied left atrial appendage (LAA) velocity. We hypothesize that an association between LAA velocity and development of POAF exists.

The blalock and taussig shunt revisited.

The systemic to pulmonary artery shunts are done as palliative procedures for cyanotic congenital heart diseases ranging from simple tetralogy of Fallots (TOFs)/pulmonary atresia (PA) to complex univentricular hearts. They allow growth of pulmonary arteries and maintain regulated blood flow to the lungs till a proper age and body weight suitable for definitive corrective repair is reached. We have reviewed the BT shunt with its anaesthtic considerations and management of associated complications.

Bidirectional superior cavopulmonary anastomosis with or without cardiopulmonary bypass: A randomized study.

Objectives: This study aims to compare the bidirectional superior cavopulmonary anastomosis (BDG) with or without cardiopulmonary bypass (CPB).

Methods: 100 patients undergoing BDG were randomized into two groups: Off-CPB or on-CPB groups. All patients underwent near-infrared spectrophotometry (NIRS) and bispectral index (BIS) monitoring and pre- and postoperative serum 100 beta protein measurements (Sβ100) and neuro-cognitive evaluation.
