background: obtaining a good sensory and motor block is the goal of performing spinal anesthesia for surgeries. the aim of this study is to compare the effect of trendelenburg position on sensory block level after spinal anesthesia with intrathecal hyperbaric bupivacine. methods: we enrolled 80 men, classified as asa i, scheduled for elective hernia repair under spinal anesthesia. participants ...

background in clinical practice, the level of sensory block in spinal anesthesia in opium abusers is lower than that in non-abusers because of adaptive changes caused by opium use. objectives the aim of this study was to investigate the level of sensory block resulting from the intrathecal administration of 0.5% bupivacaine in opium abuser patients undergoing lower extremity and lower abdominal...

background & objective: outpatient surgery can be performed by general or spinal anesthesia. spinal anesthetic drugs have side effects. many anesthesiologists choose general anesthesia, because of its relative predictability and to avoid undesirable side effects associated with spinal anesthesia. for example lidocaine is frequently associated with transient neuroligic symptoms (tns). bupivacain...

background spinal anesthesia is an important and commonly used method for surgical anesthetic in operating rooms. however, even with identical drug dosage and administration mode, the extent of drug distribution in vivo is highly variable and difficult to control. preanesthetic administration of fluids immediately before spinal anesthesia (preload) is normal practice. the choice of fluid type m...

conclusions the volume of the injected anesthetic accelerated the onset of sensory and motor block without affecting the rate of success in our patients. results the onset of sensory and motor block was significantly shorter in the 1.3% lidocaine group than in the 2% lidocaine group (p ≤ 0.05). the success rate of sensory and motor block was not different. the quality (completeness) of sensory ...

conclusions ct epidurography is not closely correlated with a clinical assessment of epidural block; thus, a clinical assessment of the sensory block is mandatory. the use of opioid analgesia in combination with local anesthetics may compensate for the lack of efficacy of local anesthetics alone. objectives the primary objective of this study was to evaluate, by ct imaging and digital multiplan...

BACKGROUND Neuraxial anaesthesia produces a sedative and anaesthetic-sparing effect. Recent evidence suggests that spinal cord anaesthesia modifies reticulo-thalamo-cortical arousal by decreasing afferent sensory transmission. We hypothesized that epidural anaesthesia produces sensory deafferentation-dependent sedation that is associated with impairment of brainstem transmission. We used brains...
