Filter by:Maternal hypotension after spinal block is a common complication after subarachnoid block in this population. The incidence of maternal hypotension is nearly 60% when prophylactic vasopressors are not used. Therefore, it is highly recommended to use vasopressors, preferably as continuous infusion, for prophylaxis rather than delaying their use until hypotension occurs. Phenylephrine (PE) is the recommended drug for prophylaxis against hypotension during cesarean delivery; however, the use of PE is commonly associated with decreased heart rate and probably cardiac output because PE is a pure alpha adrenoreceptor agonist. Introduction of NE in obstetric practice had shown favorable maternal and neonatal outcomes and was associated with higher heart rate and cardiac output compared to PE. However, there is still some mothers who develop bradycardia and diminished cardiac output with the use of NE. The most desired scenario during hemodynamic management of mothers during cesarean delivery would achieve the least possible incidences of maternal hypotension, bradycardia and reactive hypertension. Therefore, it is warranted to reach a vasopressor regimen with the most stable hemodynamic profile. In the last year, epinephrine was reported for the first time in obstetric practice with acceptable safety on the mother and the fetus. However, there is still lack of data about the most appropriate dose for infusion during cesarean delivery. This study aims to compare three prophylactic infusion rates for epinephrine during cesarean delivery.
Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is the most common complication with high costs, significant morbidity and even mortality. The major mechanisms of PEP is the papillary edema which is caused by manipulations during cannulation or endoscopic treatment. The papillary edema may cause temporary outflow obstruction of pancreatic juice, and then increase ductal pressure, resulting in the occurrence of pancreatitis. Nitroglycerin can reduce the Oddis sphincter tension, the internal pressure of the biliary tract and the pancreatic duct. Therefore, it is widely used in clinical to prevent and treat pancreatitis. Many studies found nitroglycerin might be effective in preventing PEP. And topical application of epinephrine on the papilla may reduce papillary edema by decreasing capillary permeability or by relaxing the sphincter of Oddi. There are reports that epinephrine sprayed on the papilla may be effective to prevent PEP. The investigators therefore designed a prospective randomized trial to determine whether routine using papillary epinephrine spraying in patients received octreotide can reduce post-ERCP pancreatitis.
