BACKGROUND We studied the incidence and relative risk factors for postsphincterotomy bleeding and the efficacy of epinephrine injection in hemostasis. METHODS We retrospectively analyzed the incidence of postsphincterotomy bleeding in 983 consecutive patients with sphincterotomy for common duct

UNASSIGNED Various techniques have been introduced to decrease complications during nasotracheal intubation. A common practice is to use nasal packing with a cotton stick and 0.01% epinephrine jelly. However, this procedure can be painful to patients and can damage the nasal mucosa. Xylometazoline

Epinephrine injection is an effective, simple, and economical method of endoscopic hemostasis for bleeding peptic ulcers. We measured catecholamine levels in 18 patients with actively bleeding ulcers (8 gastric ulcers and 10 duodenal ulcers) treated by endoscopic injection. Injection of epinephrine

Our goal was to determine by direct measurement of drain output whether intraoperative injection of bupivacaine with epinephrine significantly reduces postoperative blood loss in total knee arthroplasty (TKA). The study and control groups were primary TKAs performed by 1 surgeon using a

OBJECTIVE We aimed to assess the clinical effectiveness of oral vs. intravenous (i.v.) regular-dose proton pump inhibitor (PPI) after endoscopic injection of epinephrine in patients with peptic ulcer bleeding. METHODS Peptic ulcer patients with active bleeding, nonbleeding visible vessels, or

Randomized controlled trial comparing epinephrine injection plus heat probe coagulation versus epinephrine injection plus argon plasma coagulation for bleeding peptic ulcers.

BACKGROUND Epinephrine injection with heat probe coagulation is an effective treatment for bleeding peptic ulcer. Few studies have investigated the efficacy of dual therapy with epinephrine injection plus either heat probe or argon plasma coagulation for high-risk bleeding peptic ulcers. This study

BACKGROUND Although the initial rate of hemostasis achieved by endoscopic epinephrine injection for peptic ulcer bleeding is high, bleeding recurs in 14.6% to 35.5% of patients. The aim of this study was to compare rates of recurrent bleeding after endoscopic injection of two different volumes of

Severe depletion of endogenous norepinephrine was observed in the brain, heart, liver, and spleen of albino rabbits in which hemorrhagic shock had been induced. On the other hand, the epinephrine content of these tissues was significantly elevated above the levels in tissues of control animals. The

Hemorrhages of various magnitudes were performed on conscious rats, and arterial pressure, heart rate, and plasma levels of adrenocorticotropin hormone (ACTH), epinephrine, and norepinephrine were measured. Eight rats were prepared with chronic femoral arterial cannulas and received a 10, 15, or 20

Effects of dobutamine, epinephrine and norepinephrine on the hemodynamics of dogs during hemorrhagic shock.

BACKGROUND The present study examined how effective epinephrine (EPI), norepinephrine (NOR) and dobutamine (DOB) were for resuscitating dogs subjected to hemorrhagic shock (HS). METHODS Dogs (n = 42) were randomly assigned to seven test groups: EPI, NOR and DOB infusion with and without HS, and HS

In 8 chronically cannulated fetal lambs between 119 and 127 days gestation the resting plasma norepinephrine concentration was 528 +/- 77 pg X ml-1 and the resting plasma epinephrine concentration 159 +/- 42 pg X ml-1. Hemorrhage of 20% of estimated blood volume at 2% per min produced a 2.1-fold

The aim of this study was to examine the effect of the systemic administration of epinephrine against severe acute gastric bleeding in rats. Epinephrine decreased gastric hemorrhage not only before but also after lipopolysaccharide-induced severe acute gastric bleeding. Epinephrine ameliorated

The role of epinephrine in the reactions produced by the endotoxins of gram-negative bacteria. I. Hemorrhagic necrosis produced by epinephrine in the skin of endotoxin-treated rabbits.

Extensive lesions of dermal hemorrhagic necrosis occurred in rabbits when epinephrine (or norepinephrine) was injected into the skin within 4 hours after an intravenous injection of endotoxin. As little as 5 microg. of intradermal epinephrine, and 1 microg. of intravenous endotoxin, were sufficient

Optimal time delay between epinephrine injection and incision to minimize bleeding.

BACKGROUND The time until maximal cutaneous vasoconstriction after injection of lidocaine with epinephrine is often given in textbooks and multiple choice examinations as 7 to 10 minutes. However, in our experience, there is significantly less cutaneous bleeding if one waits considerably longer than

OBJECTIVE To determine whether, during hemorrhagic shock, the effect of epinephrine on energy metabolism could be deleterious, by enhancing the oxygen requirement at a given level of oxygen delivery (DO2). METHODS Prospective, randomized, control trial. METHODS Experimental laboratory. METHODS Two
