Carotid Artery Blood Flow Changes Associated with Head Positioning in Patients Undergoing Thyroidectomy.

Background And Aims: There are possibilities of insufficiency in blood flow through carotid arteries during head positioning in thyroid surgeries under general anesthesia which is usually compensated by collateral circulation in normal conditions. This compensation may be hampered in patients with congenital abnormalities or diseases such as atherosclerosis. We aimed to elucidate the changes in common carotid artery blood flow related to head positioning during thyroid surgery by Doppler examination.

Lumbar Plexus Block as an Effective Alternative to Subarachnoid Block for Intertrochanteric Hip Fracture Surgeries in the Elderly.

Background And Aims: Elderly patients with hip fractures pose a medical challenge for the anesthesiologist and are often associated with a high incidence of perioperative morbidity and mortality. We aimed to compare the efficacy of lumbar plexus block (LPB) with subarachnoid block (SAB) in elderly patients undergoing closed reduction and internal fixation for hip fractures.

Methods: In this observational study, 50 patients with femoral intertrochanteric fracture were divided into LPB group and SAB group of 25 each by convenient sampling.

Efficacy of midazolam as oral premedication in children in comparison to triclofos sodium.

Background And Aims: The perioperative behavioural studies demonstrate that children are at greater risk of experiencing turbulent anaesthetic induction and adverse behavioural sequelae. We aimed to compare the efficacy of midazolam 0.5 mg/kg with triclofos sodium 100 mg/kg as oral premedication in children undergoing elective surgery.

Effect of positive airway pressure during pre-oxygenation and induction of anaesthesia upon safe duration of apnoea.

Background And Aims: Induction of general anaesthesia per se as also the use of 100% oxygen during induction of anaesthesia, results in the development of atelectasis in dependent lung regions within minutes of anaesthetic induction. We aimed to assess the effect of application of a continuous positive airway pressure (CPAP) of 5 cm H2O during pre-oxygenation and induction of anaesthesia on the period of apnoea before the occurrence of clinically significant desaturation.

Methods: In this prospective, randomised, and double-blind study, 40 patients posted for elective surgery were enrolled.
