BACKGROUND AND OBJECTIVES Spinal block is commonly used in cesarean sections and, if some prophylactic measures are not taken, the incidence of hypotension is higher than 80%. The objective of this study was to compare the efficacy of the administration of therapeutic or prophylactic doses of phenylephrine to maintain blood pressure in patients undergoing spinal block for elective cesarean sect...

BACKGROUND Spinal anesthesia is a standard technique for cesarean section but can cause hypotension which may be related to venous pooling secondary to progesterone-induced decreases in vascular tone. This study investigated the use of a sequential compression mechanical pump with thigh-high sleeves with compression cycles timed to venous refilling. We hypothesized that this would recruit poole...

conclusions the addition of 50 mg of magnesium sulfate to a bupivacaine–fentanyl solution for intrathecal anesthesia improved the efficacy and duration of the analgesia without any significant side effects. the addition of 150 µg of neostigmine increased the incidence of hypotension, bradycardia, and nausea and vomiting. moreover, neostigmine failed to prolong analgesia duration. results group ...

www.aana.com/aanajournal.aspx Hypotension should be vigilantly prevented in patients with spinal cord injury. Recent advances in neurological, intraoperative monitoring techniques have allowed Certified Registered Nurse Anesthetists to assess the effects of spinal cord ischemia and compression as they occur. This case report describes a young, healthy man who sustained a cervical spine fracture...

BACKGROUND Hypotension is the most common problem with spinal anesthesia. This prospective study aimed to compare normotensive and hypertensive patients with respect to the hemodynamic effects of spinal anesthesia performed with hyperbaric bupivacaine. MATERIAL AND METHODS Sixty patients who were scheduled to undergo various elective operations under spinal anesthesia were included into the s...

Background: Hypotension or bradycardia after spinal anesthesia for cesarean section remain common and are serious complications. The current study evaluated factors associated to the incidences of hypotension or bradycardia in this context. Material and Method: A prospective cross sectional study from November 1, 2004 to July 31, 2005 was conducted on 722 parturients undergoing cesarean section...

Background: Relative hypovolemia may predispose to severe or prolonged hypotension after spinal anesthesia in patients undergoing orthopedic surgeries. Empirical administration of fluid preload is time consuming, costly and might lead volume overload, especially elderly patients. Therefore, predicting post great importance reserve infusion for susceptible Ultrasonographic evaluation the interna...

The recent widespread popularity of spinal anesthesia can be traced to two events. One is the appreciation that, when used for operations below the level of the umbilicus, anesthetically induced physiologic trespass is less with spinal than with general anesthesia. The other is the recognition that modest hypotension with peripheral vasodilation, that may be seen with spinal anesthesia or intra...
