INTRODUCTION: The knee-chest (KC) position is often used for spine surgery. It is considered to promote significant changes in venous return and cardiac output. However, the magnitude of these changes and their consequences on intraoperative haemodynamics and anaesthetic requirements remain to be determined. The goal of the present study was ...

Since laryngoscopy and tracheal intubation may result in hemodynamic responses in the form of increasing blood pressure and heart rate and also lead to arrhythmia and myocardial ischemia in the susceptible individuals and these changes can be even harmful for elder people. The present study was conducted to compare Alfentanil ...

BACKGROUND: The loss-of-resistance test is the most popular method for identifying the epidural space, but it cannot confirm epidural puncture. Therefore, we developed a new method to confirm epidural puncture by assessing indirect changes in epidural pressure using the Queckenstedt-test procedure, which increases subarachnoid pressure by compressing the internal jugular ...

BACKGROUND: Despite prophylactic measures, hypotension remains a common side-effect of spinal anaesthesia for parturients. Electroacupuncture at the Neiguan (PC-6) and Jianshi (PC-5) points influences haemodynamics. We thus hypothesized that transcutaneous electrical nerve stimulation (TENS) at traditionally used acupuncture points would reduce the severity of hypotension after spinal anaesthesia in patients ...

BACKGROUND AND OBJECTIVES: Electroencephalographic entropy is used to measure the degree of brain hypnosis and anaesthesia depth. Two parameters are displayed in the monitor, state entropy (SE) and response entropy (RE). Ageing leads to reduction in liver mass as well as hepatic blood flow, which decreases clearance of propofol and ...
