Magnesium as an Adjuvant to Rocuronium to Improve Intubation Conditions and Shorten the Intubation Time: A Randomized Controlled Study.

Aim And Objective: The purpose of the study is to compare the effects of rocuronium priming with the combined technique of magnesium pretreatment and rocuronium priming and to investigate whether this pretreatment could further accelerate the onset of neuromuscular blockade during intubation.

Materials And Methods:  A double-blinded randomized controlled trial (RCT) clinical study was done on patients at a tertiary care center for six months after obtaining approval from the institutional ethical committee. A total of 150 patients were randomly allocated as Group MP (infusion of 50 mg/kg of MgSo4 over 10 min was given 10 mins prior to premedication and dose of rocuronium 0.

Randomized Controlled Trial Comparing the Effects of Preoperative Carbohydrate and Non-carbohydrate Loading on Gastric Emptying in Diabetic and Non-diabetic Patients Posted for Elective Surgery.

Background Preoperative fasting for six hours and accepting clear fluids till two hours of surgery is followed as a regular practice. Carbohydrate-rich fluids antagonize catabolism and are claimed to be tolerated better. This study aims to compare the effect of carbohydrate-rich drinks on gastric volume and blood sugar control in diabetic and non-diabetic patients undergoing elective surgery with plain water.

A Randomized Control Trial to Compare Hemodynamic Parameters of Patients Undergoing Percutaneous Nephrolithotomy Under Combined Spinal-Epidural and General Anesthesia in a Tertiary Hospital.

Background And Aim: Percutaneous nephrolithotomy (PCNL) under epidural anesthesia has been reported to have few advantages over general anesthesia, like lower postoperative pain and less need for analgesics. There are limited studies on PCNL being performed under neuraxial anesthesia in supine position. Hence the present study was conceived to compare hemodynamic parameters in patients undergoing percutaneous nephrolithotomy (PCNL) in the supine position under combined spinal-epidural with general anesthesia (GA).

A Randomized Controlled Trial Comparing the Effect of Phenylephrine by Intramuscular Route With Intravenous Infusion in Maintaining Haemodynamic Stability During Elective Lower Segment Caesarean Section Under Spinal Anaesthesia.

Background Hypotension is a commonly encountered side effect in patients undergoing spinal anaesthesia, particularly in patients undergoing caesarean section. Phenylephrine is a widely used drug to treat spinal-induced hypotension and to maintain hemodynamic stability. Our aim is to evaluate the effectiveness of phenylephrine given through two different routes prophylactically in prevention of post-spinal hypotension in patients undergoing caesarean section.

Comparison of the time taken for subarachnoid block using ultrasound-guided method versus landmark technique for cesarean section - A randomized controlled study.

Background And Aims: Spinal anesthesia is the regional technique preferred for cesarean section and is usually administered using the traditional landmark technique. Ultrasonography of the spine appears to be helpful in locating the puncture site and increasing the success rate. The primary objective of this study was to assess the use of ultrasonogram in locating the lumbar interspinous space for spinal anesthesia in laboring parturients brought for elective cesarean section.

Intrinsically strained noble metal-free oxynitrides for solar photoreduction of CO.

Metal oxynitrides show promising activity for photocatalytic solar water splitting and CO reduction under solar irradiance. Precise control of cation ratios in oxynitrides is an inevitable challenge that needs to be overcome for achieving effective band gap tuning. Here we report the density functional theory-based calculations for the intricate structure-function relationships of Zn-Ga based oxynitrides and correlate the results with the experimental parameters.

Covalent Organic Framework Decorated with Vanadium as a New Platform for Prins Reaction and Sulfide Oxidation.

Chemical functionalization or docking of transition-metal ions in covalent organic frameworks (COFs) is of importance for calibrating properties and widening potential applications. In this work, we demonstrate the successful decoration of COF with vanadium as exemplified in the context of post-synthetically modifying two-dimensional COF that features eclipsed stacking structure, large pores, hydroxyl functionalities, high thermal and chemical stability using vanadyl acetylacetonate. The potent catalytic behavior of vanadium-decorated COF was systematically investigated in the reactions of Prins condensation and sulfide oxidation, which revealed its excellent catalytic performances in terms of efficacious activity, preservation of framework crystallinity and reusability.

Facile Aqueous-Phase Synthesis of the PtAu/BiO Hybrid Catalyst for Efficient Electro-Oxidation of Ethanol.

In this work, we present a facile aqueous-phase synthesis of a hybrid catalyst consisting of PtAu alloy supported on BiO microspheres. Multistep reduction of HAuCl and KPtCl salts on BiO and subsequent annealing lead to the formation of this hybrid catalyst. To the best of our knowledge, this is the first report of using BiO as a catalyst support in fuel cell applications.
