AIM The aim of the study was to examine whether ephedrine and phenylephrine were different in their efficacy for managing maternal hypotension and their effect of adverse maternal and neonatal outcome. METHODS A double-blind randomized controlled study in healthy pregnant women ASA physical status 2, which underwent elective caesarian delivery under spinal anesthesia. Patients were randomized...

BACKGROUND Hypotension during spinal anesthesia is common and can lead to severe injuries and even death. Administration of crystalloid fluids is advised to prevent occurrence of hypotension; however its effectiveness is still the matter of arguments. OBJECTIVES This study was designed to compare the effects of Ringer`s lactate and hydroxyethyl starch 6% on hemodynamic parameters after spinal...

objectives upon completion of this presentation, participants will be able to: 1) recognize mri appearance of the spontaneous intracranial hypotension and idiopathic intracranial hypertension (pseudotumor cerebri). 2) review their various clinical and imaging presentations. conclusions in this presentation we will review imaging presentations of our several proved cases. as mentioned, there are...

Background: Spinal induced hypotension is the most common intraoperative complication after spinal anesthesia during cesarean delivery. Various adjuvant techniques/drugs had been used in the past to minimize the haemodynamic effects of spinal anaesthesia. Five-hydroxytriptamine (5-HT), a serotonergic receptor, may be an important factor associated with inducing the Bezold Jarish reflex (BJR) th...

The aim of this article is to analyze the vascular dysfunctions occurring after spinal cord injury (SCI). Vascular dysfunctions are common complications of SCI. Cardiovascular disturbances are the leading causes of morbidity and mortality in both acute and chronic stages of SCI. Neuroanatomy and physiology of autonomic nervous system, sympathetic and parasympathetic, is reviewed. SCI implies di...

BACKGROUND Side effects of spinal anesthesia are hypotension, bradycardia and shivering. Five-hydroxytriptamine (5-HT), a serotonergic receptor, may be an important factor associated with inducing the Bezold Jarish reflex (BJR) that may lead to the bradycardia and hypotension in the setting of decreased blood volume. OBJECTIVES This study aimed to investigate the effect of intravenous adminis...

Background and objective: Phenylephrine is the first-line choice for prevention and treatment of hypotension during spinal anesthesia for cesarean section. However, the serious bradycardia caused by phenylephrine is a concern. This study compared the effects of prophylactic bolus norepinephrine and phenylephrine on hypotension during spinal anesthesia for cesarean section. Methods: A total of 1...

BACKGROUND Despite the high frequency of hypotension during spinal anesthesia with proper sedation, no previous report has compared the hemodynamic effects of dexmedetomidine and midazolam sedation during spinal anesthesia. We compared the effects of bispectral index (BIS)-guided intravenous sedation using midazolam or dexmedetomidine on hemodynamics and recovery profiles in patients who underw...

BACKGROUND Various types of lumbar dural punctures may contribute to neurological injury. The etiologies of dural injury include; inadvertent dural punctures due to epidurals placed for labor anesthesia, epidural steroid injections (ESI/transforaminal TESI; approximately 9 million ESI performed in the US per year), deliberate placement of intradural pain devices, and spontaneous cerebrospinal f...

INTRODUCTION Hypotensive episodes are a common complication of spinal anesthesia during Cesarean section. The purpose of this study was to compare the effectiveness and the side effects of vasopressors, ephedrine and phenylephrine, administered for hypotension during elective Cesarean section under spinal anesthesia. MATERIAL AND METHODS The study consisted of 100 selected ASA I/II females sc...
