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.

Background: Short-term peripheral venous catheter-associated bloodstream infection rates have not been systematically studied in Asian countries, and data on peripheral venous catheter-associated bloodstream infections incidence by number of short-term peripheral venous catheter days are not available.

Methods: Prospective, surveillance study on peripheral venous catheter-associated bloodstream infections conducted from 1 September 2013 to 31 May 2019 in 262 intensive care units, members of the International Nosocomial Infection Control Consortium, from 78 hospitals in 32 cities of 8 countries in the South-East Asia Region: China, India, Malaysia, Mongolia, Nepal, Philippines, Thailand, and Vietnam. For this research, we applied definition and criteria of the CDC NHSN, methodology of the INICC, and software named INICC Surveillance Online System.

Background: Short-term peripheral venous catheters-related bloodstream infections (PVCR-BSIs) rates have not been systematically studied in developing countries, and data on their incidence by number of device-days are not available.

Methods: Prospective, surveillance study on PVCR-BSI conducted from September 1, 2013 to May 31, 2019 in 204 intensive care units (ICUs), members of the International Nosocomial Infection Control Consortium (INICC), from 57 hospitals in 19 cities of India. We applied US INICC definition criteria and reported methods using the INICC Surveillance Online System.

Vitamin A is essential for human health, but current intake levels in many developing countries such as India are too low due to malnutrition. According to the World Health Organization, an estimated 250 million preschool children are vitamin A deficient globally. This number excludes pregnant women and nursing mothers, who are particularly vulnerable.

Introduction: To compare pain scores at rest and ambulation and to assess patient satisfaction between the different modalities of pain management at different time points after surgery.

Settings And Design: The ASSIST (Patient Satisfaction Survey: Pain Management) was an investigator-initiated, prospective, multicenter survey conducted among 1046 postoperative patients from India.

Material And Methods: Pain scores, patient's and caregiver's satisfaction toward postoperative pain treatment, and overall pain management at the hospital were captured at three different time points through a specially designed questionnaire.

Objective: To report the International Nosocomial Infection Control Consortium surveillance data from 40 hospitals (20 cities) in India 2004-2013.

Methods: Surveillance using US National Healthcare Safety Network's criteria and definitions, and International Nosocomial Infection Control Consortium methodology.

Results: We collected data from 236,700 ICU patients for 970,713 bed-days Pooled device-associated healthcare-associated infection rates for adult and pediatric ICUs were 5.

Background: Laser therapy, for its established analgesic properties with minimal side effects, has been used for the treatment of chronic pain. However, it has not been used for the treatment of acute postoperative pain. This pilot study was designed to assess the feasibility and efficacy of Class IV laser on postoperative pain relief following off-pump coronary artery bypass graft (OPCABG) surgery, as a component of multimodal analgesia (MMA) technique.

The incidence of eventration of diaphragm before cardiac surgery is rare. We describe the management of a patient with eventration of the diaphragm who underwent a coronary artery bypass grafting (CABG) for left main coronary artery disease followed by left diaphragm plication with video-assisted thoracic surgery (VATS) for the postoperative respiratory insufficiency.

Valvular heart disease in systemic lupus erythematosus (SLE) is associated with substantial morbidity and mortality. Current therapy includes symptomatic measures and valve replacement. SLE can present major challenges because of accrued organ damage, coagulation defects and complex management regimes.

We report on the effect of the International Nosocomial Infection Control Consortium's (INICC) multidimensional approach for the reduction of ventilator-associated pneumonia (VAP) in adult patients hospitalized in 21 intensive-care units (ICUs), from 14 hospitals in 10 Indian cities. A quasi-experimental study was conducted, which was divided into baseline and intervention periods. During baseline, prospective surveillance of VAP was performed applying the Centers for Disease Control and Prevention/National Healthcare Safety Network definitions and INICC methods.

Purpose: We aimed to evaluate the impact of a multidimensional infection control strategy for the reduction of the incidence of catheter-associated urinary tract infection (CAUTI) in patients hospitalized in adult intensive care units (AICUs) of hospitals which are members of the International Nosocomial Infection Control Consortium (INICC), from 40 cities of 15 developing countries: Argentina, Brazil, China, Colombia, Costa Rica, Cuba, India, Lebanon, Macedonia, Mexico, Morocco, Panama, Peru, Philippines, and Turkey.

Methods: We conducted a prospective before-after surveillance study of CAUTI rates on 56,429 patients hospitalized in 57 AICUs, during 360,667 bed-days. The study was divided into the baseline period (Phase 1) and the intervention period (Phase 2).

Transthoracic electrical bioimpedance (TEB) has been proposed as a non-invasive, continuous, and cost-effective method of cardiac output (CO) measurement. In this prospective, non-randomized, clinical study, we measured CO with NICOMON (Larsen and Toubro Ltd., Mysore, India) and compared it with thermodilution (TD) method in patients after off-pump coronary artery bypass (OPCAB) graft surgery.

Background: Patients with severe atheromatous disease of the aorta who underwent coronary artery bypass grafting have an increased risk of stroke and death. We hypothesize that in these high-risk patients off-pump coronary artery bypass grafting is associated with lower rates of stroke and mortality.

Methods: From January 1995 through June 2004, a total of 24,107 patients underwent coronary artery bypass grafting.

Ischemic mitral regurgitation contributes to poor survival in patients with heart failure. The intermediate-term outcome of mitral reconstruction in 15 patients who had ischemic dilated cardiomyopathy with mitral regurgitation requiring surgical intervention was studied. They underwent mitral valve repair along with coronary artery bypass surgery.

Background: Post-myocardial infarction, anteroseptal dysfunction or akinesia is treated by septal reshaping to improve the surgical outcome in patients with severe left ventricular dysfunction.

Methods And Results: Between February 2003 to December 2003, 30 consecutive patients with previous anterior wall myocardial infarction and severe ventricular dysfunction underwent septal reshaping. All the dyskinetic and akinetic septal areas were excluded using an oval dacron patch which was sutured from the healthy septal area to the anterior wall, resulting in formation of a new apex.

Objective: The recent concept of minimally invasive coronary artery surgery in selected patients has dramatically affected surgical management of coronary artery disease. We explored the possibility of coronary artery bypass grafting of anterior coronary arteries with in situ internal mammary artery through a limited anterior thoracotomy on beating heart.

Method: Minithoracotomy and direct coronary artery surgery without cardiopulmonary bypass (CPB) was attempted in 116 patients.

Objective: To achieve complete myocardial revascularisation in patients with diffuse coronary artery disease, patients with inordinately high risk of cardiopulmonary bypass (CPB) like severe systemic disease or diffuse atherosclerosis of the aorta.

Methods: We have adopted the technique of combining coronary artery bypass grafting (CABG) with transmyocardial laser revascularisation (TMLR) using 1000 W CO2 laser machine. TMLR is done to areas supplied by ungraftable arteries, while CABG without cardiopulmonary bypass is done to the left anterior descending artery (LAD) and/or right coronary artery (RCA).
