Recently, some scholars suggested that it is important to keep a stablehemodynamic state and prevent the stress responses in geriatric patients undergoing total hip replacement (THR). We conducted this randomized prospective study to observe anesthetic potency of unilateral spinal anesthesia and stress response to it in geriatric patients during THR. We compared the effect of unilateral spinal ...

Objective: To determine the dermatomal level of sensory block after spinal anesthesia traditionally used method is pinprick test. Pinprick test is an invasive and painful method. We aimed to compare the dermatomal levels of sensory block determined by noninvasive simple tests touch and cold sense loss with routinely used invasive pinprick stimulation test in clinical practice. Materials and Met...

Background: General anesthesia with endotracheal intubation has remained the most common technique used for open renal surgeries because of the abnormal body position and its ability to control the diaphragmatic movement during the surgery. Combined spinal and thoracic paravertebral block (TPVB) can be used as alternative technique for open renal surgery, where spinal anesthesia provides fast a...

A simple cryogenic device is described. This device is capable of cooling neural tissue in contact with the probe and maintaining the tissue at the desired temperature for extended periods of time. The cold probe can thereby reversibly block neural transmission through small portions of the spinal cord white matter. Interruption of axonal transmission is achieved by placing the tip of the devic...

PURPOSE Fracture of femur is a painful bone injury, worsened by any movement. This prospective study was performed to compare the analgesic effects of femoral nerve block (FNB) with intravenous (IV) fentanyl prior to positioning patients with fractured femur for spinal block. PATIENTS AND METHODS Sixty-four ASA I-III patients aged 18-80 years undergoing surgery for femur fracture were randomi...
