ABSTRACT

Objectives: In this study the authors have tried to examine the role of magnesium alone or in combination with diltiazem and / or amiodarone in prevention of atrial fibrillation (AF) following off-pump coronary artery bypass grafting (CABG). Background: AF after CABG is common and contributes to morbidity and mortality. Various pharmacological preventive measures including magnesium, amiodarone, diltiazem, and combination therapy among others have been tried to lower the incidence of AF. Most of the studies have been performed in patients undergoing conventional on-pump CABG. In this uncontrolled trial, efficacy of magnesium alone or in combination with amiodarone and / or diltiazem has been studied in patients undergoing off-pump CABG. Methods: One hundred and fifty patients undergoing off-pump CABG were divided into 3 groups, Group M (n=21) received intraoperative magnesium infusion at 30mg/ kg over 1 hour after midline sternotomy; Group MD (n=78) received magnesium infusion in similar manner with diltiazem infusion at 0.05 µg/kg/hr throughout the intraoperative period; Group AMD (n=51) received preoperative oral amiodarone at a dose of 200 mg three times a day for 3 days followed by 200 mg twice daily for another 3 days followed by 200 mg once daily till the day of surgery along with magnesium and diltiazem infusion as in other groups. AF lasting more than 10 min or requiring medical intervention was considered as AF. Results: The overall incidence of postoperative AF was 12.6% with 11.7% in group AMD, 19% in group M, and 11.5% in group MD, which was not statistically significant. Conclusions: It is concluded that the use of amiodarone and/or diltiazem in addition to magnesium did not result in additional benefit of lowering the incidence of AF.

ABSTRACT

Background and objectives Propofol-based sedation is one of the most commonly used methods for endoscopic retrograde cholangiopancreatography (ERCP). The commonest complications during ERCP are in the form of adverse cardiopulmonary events as a result of sedation. Etomidate has a more stable cardiovascular and respiratory profile than propofol and has been used for sedation in simple gastrointestinal endoscopy but has not been studied for procedural sedation in ERCP. The objective of the present study was to compare the safety and feasibility of etomidate and propofol for sedation during ERCP procedures. Methods This single-center, randomized trial included 100 American Society of Anesthesiologists (ASA) physical status class I to II patients who were scheduled for ERCP. All patients received midazolam 0.02 mg/kg, lignocaine (2%) 1 mg/kg, and fentanyl 1 µg/kg intravenously, followed by etomidate or propofol according to the group allocation. The primary outcome was to compare the mean arterial pressure (MAP) at various timepoints between the two groups and secondary outcomes were to compare oxygen saturation, induction and recovery times, and adverse events. Transient hypotension was defined as any decrease in MAP below 60 mmHg or 20% below the baseline. Transient hypoxia was defined as desaturation (saturation of peripheral oxygen (SpO2) <92%) lasting for more than 10 seconds requiring airway intervention. Results Fifty patients were enrolled in each group (Group E: etomidate and Group P: propofol). Transient hypotension occurred in eight (16%) patients in Group P, and two (4%) patients in Group E (P= 0.045). Baseline MAP was comparable between the two groups but was significantly lower in Group P at three timepoints during the study. Nine (18 %) patients in Group P had a transient hypoxic episode, compared to none in Group E (p= 0.006). The induction and recovery times were similar in the two groups. Conclusions Etomidate offers better hemodynamic and respiratory stability than propofol and can be recommended for use during ERCP in ASA I/II patients.

ABSTRACT

The coronavirus disease-2019 (COVID-19) pandemic has put healthcare services all over the world into a challenging situation. The contagious nature of the disease and the respiratory failure necessitating ventilatory care of these patients have put extra burden on intensive care unit (ICU) services. India has been no exception; by March 2020, the number of COVID-19 patients started increasing in India. This article describes the measures taken and challenges faced in creating ample ICU bed capacity to cater to the anticipated load of patients in the state of Delhi, India, as a result of the COVID-19 pandemic. The main challenges faced, among others, were estimating the number of ICU beds to be created; deciding on dedicated hospitals to treat COVID-19 patients; procuring ventilators, personal protective equipment, and other related material; mobilizing human resources and providing their training; and providing isolated in-house accommodations to the staff on duty. The authors acknowledge and agree that the methodology proposed in this article is but one way of approaching this difficult scenario and that there could be other, perhaps better, methods of dealing with such a problem.
