Introduction: Patient positioning for spinal anaesthesia in patients with femur fracture is extremely painful and various methods have been tried to reduce mobilisation pain.

Aim: To compare the analgesic efficacy of intravenous dexmedetomidine, ketamine and femoral nerve block in patients posted for fractured femur for alleviating the positional pain before spinal anaesthesia.

Materials And Methods: A total of 75 patients (25 per group) of American Society of Anaesthetists Grade I-III patients of age group 18-80 years with fractured femur scheduled for elective surgery.

Background And Aims: Intravenous sedation during spinal anesthesia has the advantages of increased duration of spinal anesthesia and better postoperative pain control. The aim of this study was to compare the effect of intravenous bolus and infusion of dexmedetomidine versus ketamine given intraoperative on the postoperative analgesia in fracture femur patients operated under subarachnoid block.

Material And Methods: In this prospective randomized double-blind controlled study, 75 patients aged 18-65 years posted for elective surgery were selected and randomly divided into three groups to receive ketamine (group K), dexmedetomidine (group D), and saline (control group C).

Background & objectives Spirometric glycopyrronium responsiveness, a new advent, needs to be examined at in terms of degree and frequency in different obstructive-airway diseases diagnosed in real world practise. Methods Serial and willing symptomatic affected individuals of suspected airway disease underwent a pragmatic post-consultation spirometry-protocol on the same day with salbutamol followed by glycopyrronium bromide. The diagnosis of asthma (FEV1-reversibility ≥ 200 ml + 12%), chronic obstructive pulmonary disease (COPD) (FEV1/FVC<0.

Background: The use of silver nanoparticles (AgNPs) in biomedicine has emerged in a big way owing to its antibacterial and anti-inflammatory properties. We hypothesize that combining the AgNPs with antibiotics for coating sutures will enhance the antibacterial property of sutures with the added advantage of the immunomodulatory effect of AgNPs on tissue healing.

Materials And Methods: Polyglactin sutures were coated with AgNPs using the dip-coating method.
